Loving this phone so far except for one thing. When recording in low-light, there is a significant decrease of fps.
I realize that the 28mm f/2.0 lens is the best out there so why would HTC pair it with such a crippling software feature???
I'd rather have the software crank up the ISO or lose a little exposure to keep the video at a steady 30 or 24 fps instead of the stuttering/lag effect.
Some of my videos in low-light areas are averaging 20/fps.
Do any of you know if HTC usually updates the camera software or if an outside dev would come out with a camera hack allowing us to lock the framerate?

alot of expensive video cameras will do this also.
it has to slow the shutter speed to let in more light. otherwise if you increased the shutter speed you wont see anything. i guess they could add a shutter speed control to let you increase that and ramp up the ISO.

Shutter speed is for pictures, lol. I am talking about frame rates for videos.
I am more than happy with the htc one for pictures but for low-light videos, I would love it if I can lock my frame rate at 24 or 30 fps for my entire video.
I would rather have less light/more ISO instead of choppy videos.
I think HTC allows the drop in framerate to keep the ISO the same.

I've never facepalmed so hard before.
Shutter speed applies for both pictures and videos; with videos, it's the amount of time the sensor (or that particular slide of film, in the 'old days') captures light for a frame in said video.
If it's low light, the video needs to let in more light by increasing the amount of time the sensor captures light for a given frame. Thus increasing the shutter speed.
Now, here's where frame-rate comes into the picture (see what I did there? ;D)...
For example (I'm not using real numbers here, as I don't know what numbers are used for the One, plus maths isn't my strong point. But...) in normal lighting the frame rate is 1/30th of a second, and it's shooting at 30fps. All's well.
However, if it's in 'low light mode', it'll need to lower the shutter speed to 1/20th of a second (again, just example numbers). It'd then need to lower the fps down to 20fps.
TL;DR: pictures and videos both have shutter speed.
Um, I'm sorry OP, can you point to the phone that is currently shooting usable 60fps video in low light?
Maybe in a few years. Right now you just have to deal with the current state of the art instead of complaining that HTC is making crappy decision decisions.
You could probably have 30fps video in low light right now. It will just look very very dark.
I'm guessing if they went that route, you'd complain about that decision too.

Gotcha. But the shutter speed isn't always controlled by the fps. On my T2i, I can record at 30fps while leaving my shutter speed at 1/30th or change it to 1/400th while changing the f stop or ISO, which results in crystal clear motion captured. I always believed shutter speed is always independent of framerates. For the HTC one, i would love it if the fps was locked regardless of shutter speed per frame or iso or aperture.
The choppiness really creates unusable footage.

Actually, that's exactly what I am asking for. The option to choose a choppier footage with more light or have 30fps video in low-light at the compensation for darker exposure or more ISO.
Recording at 720p @ 60fps in low-light still results the framerates dropping below 24 which I consider is unusual footage.
I guess I'm the only one feeling like HTC made a poor decision by not locking the fps but when my footage goes from 30 fps to 20 fps in less than 1 second, the footage is really undesirable. They could've easily just raised the ISO or aperture like the s3, lumia 920, or iphone 5 do.
Actually, that's exactly what I am asking the choice for.
So noted.
Raising ISO is a fancy way of saying turning up the gain which will also amplify the noise in the sensors, creating some very grainy video.
That probably wouldn't be very desirable either.
It's all about tradeoffs.
Phones, more than other devices, tend to have a very fluid idea of frame rate. If you need it nailed up at 30 fps no matter what, you're right, this may not be the camera for you.

Grainy videos can be treated or processed with filters. There is no alternative to frames that are lost.
I didn't mean to go on debates about ISO or shutter speed.
Instead of returning the phone, I was asking the community if they happen to know if HTC updates the drivers for the camera at any point or if someone would develop a camera hack that addresses this loss of frames or the choice.

Because the T2i doesnt fit in my pocket, lol.
I had an HTC Evo, and in those days they would drop frames in *good* light. It was extremely frustrating. I bought faster SD card storage, overclocked, switched to performance governor, BFQ scheduler, the works.
I searched high and low for mods that would lock the frame rate. I wasn't the only one searching, gamers are always interested in fps as well.
If that mod was made, I missed it. Maybe it's possible. I'm as curious as you are to see if anyone has info on this. My expectation is no. HTC's camera drivers are closed source and seem to defy this kind of hacking.
Anyway, now you see why, coming from older technology, I'm so grateful for the excellent low light video the One *does* have. ; )

OP, you aren't the only one who feels the fps in low light video recording drops too low. I'm also annoyed by it. Furthermore I know higher fps is possible because if you record in HDR mode the fps are higher in the same lighting situation. I believe this is because it cranks up the ISO/gain in order to get double the fps or more since it needs high and low exposure frames to combine together behind the scenes. Try HDR mode and see if you get better fps. Downside is it is definitely noisier in low light, can have higher filesizes, and also the sides of picture are significantly cropped to leave some room for electronic image combination/stabilization during the HDR processing.
One other trick you can try is setting the exposure lower, this seems to result in faster shutter speeds/higher fps.
So yes I also wish the ISO and/or fps would be more controllable in the varios video recording modes. I tried some of the other special modes and no luck. Also I wish there was an infinite focus lock, so far I can't find that either. Seems like such a basic feature missing?
You will get a laggy video in a low-light scenario even you managed to lock the fps. Because the device dose need more time for capturing more light in one frame.
So,smoother = darker.Vice-versa.
FPS drop is not acceptable. My 4S can shoot in low light without any drops...so I'm pretty sure it's a software problem that can be fixed by HTC.

I did some more testing. ISO and exposure settings only seem to effect pictures. When it comes to recording videos, we only get one set of options (slow mo, 720 @ 60fps, and HDR). I recorded a bunch of similar situation videos with various ISO and exposures and while it does change on screen, the moment you press the record video, it reverts back to all auto except for the 1 set of options reserved for video recording.
Various ISO/Exposure settings resulted in most videos looking similar and averaged from 20-22 fps. The one I recorded at 720 @ 60 was unwatchable at an average 15 fps. The HDR was well lit and had a tremendous amount of noise yet averaged 17 fps.
For comparison, I recorded the same situation with my iphone 5 on auto and my galaxy s3 on night setting. The iphone 5 had a little more noise than the HTC, exposure was slightly darker than the HTC, but was the video was fluid and yielded an average of 25 fps. GS3 @ Night setting had less noise than the iphone, visibility was darker but the video was smooth at 27 fps.
My conclusion is that both apple and samsung have coded in their recording software to NEVER dip below 24 fps while HTC allows the camera software go as low as 15 frames per second.
In a world where the iphone 5 and HTC one share the same camera technology and share the same lens, this would make sense. But in this world, the HTC has a far superior lens. A wide angle 28mm with OIS at f stop of 2.0 definitely has power to deliver better results against lesser lenses.
I truly hope that somebody or even HTC can unleash the lens to its full capabilities.

spot on, thanks for explaining this to the OP. i didnt want to start a discussion about it so thanks.
Completely agree that they need to tweak the vid recording modes to increase fps. Regarding the exposure "working", I have found using a 3rd party recording app (in this case, the dashcam software VideoRegPro) it has exposure settings that do work, and not just in the preview. The upside of cranking down the exposure all the way is you get a much darker picture, but this can somewhat be fixed by also cranking down the contrast setting. You end up with a very flat looking image with not enough color, and also get some blueish noise in black areas. Still hoping a future HTC update improves the low light FPS, at least in one or two of the special video modes. And also hoping for a working infinite focus (useful for a dashcam).

When recording video with Cupcake, what framerate are people getting for their videos? You do get the framerate by going to Gallery. Long click on the video and select info. I'm only seeing 4-9 frame/sec. I think it's because my memory card is class 6. Thanks.
I've seen frame rates range from 19fps to 4fps. I've found that videos of well lit areas or outdoors produce higher frame rates.
I got 19 fps (outdoor shot)
/Mats
The brighter it is, the shorter the required exposure and therefore the higher the framerate that is possible. If its so dark that you need a 2 second exposure, you'll only get at best 1/2 fps.
Does anyone know of the ISO sensitivity of the camera is adjustable? If someone could figure that out, I bet the still camera AND video recording would be faster. I've seen the ISO adjust a little, but not much.
Max frame rate is locked at 20. A note in the source says anything higher and it becomes unstable.
but why? the cpu can handle up to 8mpix still and 30fps recording video afaik oO
The framerate I'm usually ok with, it's not great but usually 15+ which is decent. The resolution (CIF, 352x288) and video quality (super compressed mp4/H.263) blows chunks though. Absolutely horrible and a disgrace for a smartphone in 2009, it's as bad as my three year old Samsung U600 dumbphone. A two year old Nokia N82 can at least shoot video at VGA resolution and use less video compression, at up to 30 FPS, despite a much slower processor. I can't express how disappointed I am. Is the camera and/or hardware in the Dream really that bad or is this a software thing?
In other words, this is merely a software incapability, not a hardware issue. Meaning, I'm sure one day we will be able to see significantly increased video quality and so forth.
Topic says it all, when shooting video in dark situations framerate drops to 10 - 12 -17 so it's frustrating! Since the specification of the video says that the variable frame rate if there is a chance to somehow locked at 30fps!
Great magicians of hacking help please!!!
Nope, wait for a update from HTC and hope for the best... (for now anyway)
Even if we set Exposure to -2 and ISO to 800 we can't achive 30 fps, so, if we lock frame rate to 30, in low light, it is possible that the video is to dark for us to do anything with it.
IMHO DHD have a poor camera sensor for low light.

I really dont care how much noise will be introduced. 30 fps is most important. Is this even possible for a developer here to work on since this is HTC's own app and i think HTC dont release their source?
Have you tried shooting with flashlight on? Or setting the white balance manually, I'm sure I read somewhere that helps, turning off automatic white balance removes the annoying changes in brightness and helps improve framers alongside setting exposure to manual.
Be nice if it just shot un 30fps all the time like iPhone, I'm sure it will be sorted.

Do you own a Desire(old one)?From what you say I guess you don't.With the Desire,if you set the ISO to 800 you can record anything between 25 and 30 fps,even in low light.It introduces some more noise,but not that much more that what the iPhone does in low light.Dunno why the DHD doesn't change much with the iso...
So, is there a way to record at 30fps at night?I searched all over the forum and didn't find a way.(besides reducing the exposure which makes videos very dark)
I noticed a thing that when I focus the objects aren't so shadowy because of low fps but only just for a moment like half of second and then it returnes to the normal 10-15 fps.

Nah dude there probably is no way. It's the hardware here that's the problem here.
The problem is that the sensors in your camera need a certain minimum amount of time to get the picture to look correct.
I could tell you how to get it locked at 30, but then you would hate me because your video would turn out extremely blurry, and to that extent, so dark that you might as well have just recorded a black sheet of paper.
(This would of course come with rooting your phone, which I wouldn't think is a problem)
The thing is, its been coded into your device to reduce the frame-rate, so that you at least get a scene in a video at a bad frame rate, instead of black in a video with good frame rate
Yeah, but as I said before, there is a thing that when I focus the video there is a small interval of time(about 1/2 sec) when the frames seem to be normal(25-30).I don't know if this happens only on my device but before the gingerbread update I didn't notice this.You could try it or I can even send you a recording.And why does the camera sensor state that it can record @60 fps in light and 30 fps in dark?(according to this thread p=13510330)
I don't know very much about its camera and I don't say that I am right about this, but I want to improve the recording as much as possible.Even my friends MOTO Defy is better in low light.
Also will a custom rom improve the performance of recording?

I don't think any sensor manufacturer can specify framerate in "dark" because how do you define "dark"? What your eyes percieve as "dark" is more like "pitch black" for a camera sensor. Especially a small crappy one that sits behind a small crappy lens. Remember that to have 30 fps, you should be able to "gather" enough light to make a properly exposed image for a 1/30 of a second. Take your point-and-shoot camera, or even a DSLR, set it to manual mode, set the ISO to 800, set the shutter speed to 1/30, set the aperture to f/8 for a 28mm equvalent focal length (if you are using DSLR, for a point-and-shoot with a smaller than DX sensor, you have to dial it even higher) and see what picture you can get with those settings. This is how much light hits the sensor for 1/30 of a second. This is how your videos will look like.
EDIT: You should not compare video recording framerate on phones that record in different resolution. DEFY can record up to 640x480 (if I'm not mistaken) which is 1/3 of the frame recorded with the DHD (1280x720). With a good recording algorithm this means three times more light per pixel (if the sensor is the same).
Hey guys,
I know a lot of people with this phone are happy with the frame rate of videos in good light (30 fps constant). But one thing that really does my head in is the shocking frame rate in low light (like indoors).
Well fear not chums, supremebeaver is here to put your fears to rest
Steps:
- Open camera (not camcorder) app. Set ISO to 800
- Open Camcorder app, set Exposure to -2.
- Notice improved frame rate in viewfinder.
- Smile
I will admit, the quality suffers a little. The video gets a lot darker but imo its a good compromise for smoothness. At least for me. I was able to go from 9 fps with stock settings to 25 solid with those settings changed.
Enjoy
if you want to know why this works, heres how:
at 30 Frames Per Second, each frame of video has a minimum exposure time of 1 thirtyith of a second, or 1/30 seconds.
in low light this is does not give the camera enough time to gather light to expose an image, so it slows the exposure time down, saaaay, 1 fifteenth. this reduces the frame rate to 15fps. this gives the camera twice as long to expose an image.
by changing the exposure to -2 you are telling the camera not to increase the exposure time and so you end up with a darker image but better frame rate.
this is not something that can be magically fixed by a firmware update, its simple photographic physics.
the only thing a firmware fix will do is turn the default ISO up.

but why is the cam on htc hd7 have faster fps than hd2 when they got the same specs? hd7 has WP7 and hd2 has WP 6.5. is it the o/s?
The HD7 has the same chipset as us, the HD2 has the last generation of snapdragon (the same one as the classic desire).

Consider using the built-in flash to compensate for that darker image issue
it would be nice if we had a brightness setting, like LG camera does. There, you can also boost ISO to 1250.

but the noise will be too high.. like on the iphone 4, they raise the ISO so high to maintain framerate but all u get is a super grainy video that looks rubbish.
Technology for phone cams still has a long way to go...
I'm a video editor and have been shooting and editing video professionally for the past 7 years. I don't work for Samsung, Sprint, or any affiliated companies.
The camcorder lags in low light because the shutter rate of the camera has to slow down in order to capture the image. The shutter rate is how many times the shutter has to open and close in order to take in light to make an image. On a nice sunny day outdoors, the light sensor can easily take in the light. Hence, you get a high shutter rate. Sometimes up to 1/5000 depending on the camera.
When you're shooting in low light situations, the sensor has to be open long enough in order to take in enough light to make an image. Thus, the shutter rate decreases to about 1/10 or so. When the shutter rate decreases, your camera can make a nice low light picture... but you get blur, grain, and what looks like a slower frame rate.
So, this camcorder "lag" you speak of in low light is NORMAL. It's inherent to all video cameras in low light. If you want a better image... get some lights!
If the low light performance on the camcorder was better with a different build, like in DI18, they probably locked the shutter rate at about 1/30 in order to keep a good framerate, but the low light performance wouldn't be as good as you have now.
TL/DR: It's normal. They just reduced the shutter speed so you can get a BETTER image in low light. Want a better image? Film in better lighting!
Edit: What Samsung should do to fix this is to lock the shutter rate at about 1/30. You won't get a good low light image, but the motion will be consistent. Seems to me you guys want good motion and not a good image. You can't have both in low light situations. You have to choose one or the other.
Thanks for your expert advice.....but we'll wait to hear back from someone that actually writes code

The camcorder lags in low light because the shutter rate of the camera has to slow down in order to capture the image. The shutter rate is how many times the shutter has to open and close in order to take in light to make an image. On a nice sunny day outdoors, the light sensor can easily take in the light. Hence, you get a high shutter rate. Sometimes up to 1/5000 depending on the camera.
When you're shooting in low light situations, the sensor has to be open long enough in order to take in enough light to make an image. Thus, the shutter rate decreases to about 1/10 or so. When the shutter rate decreases, your camera can make a nice low light picture... but you get blur, grain, and what looks like a slower frame rate.
So, this camcorder "lag" you speak of in low light is NORMAL. It's inherent to all video cameras in low light. If you want a better image... get some lights!
If the low light performance on the camcorder was better with a different build, like in DI18, they probably locked the shutter rate at about 1/30 in order to keep a good framerate, but the low light performance wouldn't be as good as you have now.
TL/DR: It's normal. They just reduced the shutter speed so you can get a BETTER image in low light. Want a better image? Film in better lighting!

Wrong. You failed to understand the issue. This eb13 has either flawed drivers or the wrong ones. The dk28 froyo beta works flawlessly. I personally tested both builds. This is a programmers error that should be patched soon. When the patch is given, it should work as good as eclair or dk28.

It appears that on the older builds the camera gained up to deal with lower light situations. On the current build it slows the frame rate (not the shutter rate) even normal indoor lighting. You shouldn't do that with video. This would be fine on a still camera but totally unacceptable in video, even amateur video taken with a cell phone.

Here's the problem: You didn't say what the problem is. You just said "it doesn't work". What doesn't work? Please accurately explain and DETAIL the problem with the camcorder in EB13.

Theres nothing wrong about what he said. He said that the programmers did it. They locked the shutter rate in DI18, to prevent lag. It just causes a lower quality video. The videos in low light were darker in DI18, but faster. Which is what he is saying.

The shutter rate slows down the GOP, but the frame rate remains constant.
It's not "normal". If you're really a video editor, you'd know that. Being able to explain an effect doesn't make it "normal".
That's like saying "I can explain your cancer. Cancer is just when cells mutate and crowd out other cells. It happens to a lot of people. It's perfectly normal!"
Phone sensors are smaller and therefore not as sensitive to light as sensors in professional or even semi-professional cameras. (Larger sensors can capture more light; just the laws of physics.) So image quality on phones is always a compromise.
However, the solution to this lack of light-gathering ability should not be to hold the shutter open for such a long time that it ruins the frame rate. That's cutting off your nose to spite your face. And no one should accept it.
I think we are all fine with a little graininess in the artificially boosted low-light images from our Epic camcorders as long as it means we have a stable frame rate. This is the way every other low-end camera works and it's the way this phone used to work, and should still work.

Fine, I figure everyone is aware of the bug. Go to a very dark room and launch the camcorder. Maybe turn on the tv so that's the only light source. Now pan around the room. You see that god awful blur? That's because the camera is barely pushing 5 fps. Compare that to eclair or dk28, in which keeps a steady healthy 30 fps with absolutely no frame drops.

correct. Being a pro photographer should hint him that its not normal. But we ask make mistakes. Just like samsung or sprint made resulting in what we are experiencing. Btw, sprint acknowledges the camera bug aswell.
It would be nice if they could just make options like the gain user adjustable so that we could tailer that setting to whatever lighting environment we're in....like the iso on a still cam.
I know that before when I had DK28, my videos would not capture past 3 seconds, I would get a message saying Recording Failed. With the new build this doesnt happen.

How long do your recordings last now? Mine fail around 2 minutes, using a class 6 sd card. Never happened before.

There's an option to free record and to limit for MMS. However, I've had recording fail a few times on DK28 when I was on free record. I figured I had too many programs running in the background.
I've recorded a few times at varying lengths in EB13 and haven't had any problems so far.
The point is, something that worked fine before, (smooth video recording indoors) doesn't work now. It's not normal, anyone who has seen it can tell it's not normal.

Samsung probably wanted you to get the best picture out of your camera and lowered the shutter speed to not add any artificial gain.
It's damned if you do and damned if you don't. Add gain and people complain about grain and artifacts. Slow down the shutter rate and get slower playback. Don't shoot the messenger here!

True. I'll add this to my original post.
I'll gladly take graininess over a what looks like a blurry Peter Gabriel video.

Here is a video I shot of one of my DJ friends in low light using only the camera flash as the light source on my phone (along with the various disco/club lights). Even in low light, the frame rate was very smooth.
After the EB13 update, the fps is horrible and I would never be able to shoot this same video in the phone's current state.
Hi community.
One of the major reasons I got this phone is its claimed 60fps video capture capabilities which I was told was comprable to the iphone 5s'slowmotion mode. Thing is, I have come across something that I was wondering if other G2 owners could confirm.
60 fps video seems to only work under optimum lighting conditions. When indoor or under low light conditions, it drops to as low as 15 fps captures. Thus something Ive confirmed when importing into Adobe premiere. Capture fps is actually variable and depending on lighting conditions, the file is recognized at its slowest framerate. This is very disappointing and raises other questions for me:
1. 60fps is interpolated by cpu and not sensor capable?
2. Sensor cannot compensate hfr with autofocus/shutterspeed?
3. My cpu is too underclocked (24k antutu) to handle hfr.
Any insight would be much appreciated since i have only one more week to exchange for a iphone 5s.
Have you checked out this thread?

also constant 60fps issues will cause light issues - likely the cause of the problems here : http://www.imore.com/how-quality-your-iphone-5s-low-light-video - check out morac's comment at Nov 12, 2013 at 9:19 pm
Thanks Andybites.
I didn't expect to be relying on mods to get capabilities they have been marketing to function properly. Nice to see I would have encountered similiar low light issues with Iphone 5s, though their frame rate is still constant as opposed to framerate AND low light issues of the G2's stock camera.
15fps is unacceptable and would rather have consistent framerate so when my footage moves outdoor to indoor within the same shot, my footage won't look like its chugging like a video game being run with a bad gpu.
I'll try the camera mod you suggested and report back. Thanks again.
Rumor has it that both Google and LG are working on a software fix for both their cameras.
Steady frames > light compensation. Simply bad software.
