improve camera quality

Quality of camera for trinity is quite good but I don't like the 15 fps movies.
So I went to
HKLM/SOFTWARE/HTC/Camera/Recparam/MP4Large/Framerate
and changed the value from 15 to 30.
I get fluid movies but bitrate stays the same and picture quality is going down.
so I tried to change the BitRate value (384000 by default) but there is no effect. You can put whatever you want, the compression is controlled somewhere else.
Is there a way to increase this bitrate? I don't mind if movies get big as long as quality is improved.

Can you tell mi what is the maximum available video recording resolutin with Trinity and what frame rate?

maximum recording resolution is 352*288 (mode CIF).
In fact I checked that if you change the value:
HKLM/SOFTWARE/HTC/Camera/Recparam/MP4Large/
"Bitrate"=384000
Then whatever value you put the resulting file will be encoded with a default value of 192000.
Nobody has a clue of how the real bitrate is defined for the encoder???

192000 is the value for MP4medium and MP4small profiles.
Isn't it strange?
It's like if you change the value for MP4Large it falls back on MP4medium bitrate value...

Are you sure that trinity actualy record video in 30fps after registry hack? To bad bitrate can't be changed, is mp4 only available format for recording?

I tried it too, indeed de 30 fps tweak works, but bitrate is terrible.
I hope anyone got an idea how to fix this thing.

Did you try a slower frame rate, like 25 fps? It is still a pretty good speed.

I'm wondering how powerful that ATi chip in the Trinity is. If it can handle 30fps with a higher bitrate... let's see if we can squeeze the most of it!

From what I've read, the ATi video chip is not being fully utilized by the ROM, maybe when we get an upgrade that will change.

Not much is being utilized by the current ROM is there? I mean, it's seriously disappointing that HTC decided to release the Trinity with so many features disabled or toned down.

Agreed that most of the build-in features were disabled or not turned up fully, GPS, USB-Host and now Ati Chips. How HTC can release a "Full features" ROM soon.

Just wondering if anyone's who flashed their Trinity with one of the latest test ROMs noticed any changes to the video performance.

Anybody solve this problem?

also want to im prove videobitrate...
any clues?!

push need help
how to increase videobitrate

1. total amount of memory must be constant (I think)
2. more fps less bitrate
3. decrease fps and increase the bitrate

Video recording on the Nexus and Bitrate vs 3GS

I have an iphone 3gs and the nexus one. Ive recorded video on both and when I transferred the video to my PC, I noticed the bitrate is on the low side compared to the iphone 3gs.
The 3gs gets 7,000+kbps while the Nexus one gets 2,000+kbps.
Knowing this, is there a way to get that bitrate to be higher? Closer to that of the 3gs? Is it due to the app or the camera on the nexus one? As good as this phone is, isnt it suppose to be better at recording video than the iphone 3gs or at the very least on par? What can I do to get the bitrate up? Its bad enough the FPS is around 17-20 compared to 30fps for the iphone 3gs but bitrate being so important to me, what can I do? I really like android OS but cant keep the phone if its video recording is going to be a couple notches lower than the 3gs. What do I do here?

That's really stupid I expected this phone to have a more capable camera. The comparison YouTube video I watched made the iPhones video recording look brighter and more vibrant with equal clarity but I thought the nexus had better specs in video recording. I know the iPhone has 3.2 MP to nexus's 5mp but I thought recording was supposed to be better on nexus.
Can anyone explain? I've read the respective specs but my eyes don't lie. And are software modifications/updates capable of increasing the quality of photos and recordings? Thanks
Also, why did I stop having a cursor when typing in xda? I had one when I got the phone...I didn't want to start a whole new thread to ask that...

I assume it may be the compression where 3gs = mov and nexus one = 3gp. However it is possible that this may be more of a hardware limitation than something as simple as compression.
I didnt even mention the audio recording which is pretty sub par. Im talking audio recording equivalent to phones from 2002. 8khz bit rate, seriously?

The wrapper doesn't mean anything. Bit-rates don't either. Both .mov and .3gp are merely the headers and footers of video files. The main block, and the one that really matters is the codec being used. I can tell you that iPhone 3GS uses H.264, and the Nexus one probably does too since it's the exclusive codec of youtube , which is today's gold standard in video compression. Now, if each phone is using the same codec, you can turn on and off settings suit your needs. If you have more processing power, you can use that to shrink the file more. If you want the best battery life, you don't compress it as much.
Having said all that, 6Mbps is rather lousy compression for VGA output if Apple is using H.264. Full frame DVD quality is around 3Mbps properly encoded, and even taking into account the 3GS has to encode in real-time, and shoots 30 progressive frames a second (DVD's are around 24fps) 4Mbps would be the max if the camera was good, which is isn't (not bashing the iPhone specifically, all cell cams suck). 7Mbps would be reasonable if you were shooting 720p, but the 3GS can't do that.
So...summarizing
The Bitrate on the iPhone video seems insanely high, wastefully high. The Nexus One seems better, but is a little too low. Then again, I don't know what you're shooting so I'm just guess. 2Mbps could be perfectly fine if there isn't much movement.

The camera has nothing to do with bitrate. Here's a random frame from an ep of House, ripped from one of my DVD's and re-encoded using the same codec used by these phones, just with the quality settings set REALLY high. The bit rate on this episode is...drum roll please...2,000Kbps. It looks far better than anything the iPhone can shoot because 1)The camera used to shoot it was really nice and expensive and 2)It was encoded and re-encoded using software and hardware a lot nicer and more capable than you can fit on a phone.

You're seriously basing your smartphone decision on its videorecording capabilities? If bitrate and/or video quality is 'so' important to you, why are you trying to record video with a phone to begin with? You can get a much better video camera for $600...

Video recording question

I'd like to use my Note to record a mini training session (on the computer monitor). I guess I'd be recording about 1-2 feet from the screen for a total of 20 minutes. I think it's far enough to be able to still read the words on the monitor.
Anyway, I tested out the recording options and here's what I found so far:
3840x2160 for 20 seconds of recording is 130 MB (~400MB/min of recording)
1280x720 for 1 minute of recording is 92.5 MB (~90MB/min of recording)
The next lowest resolution is 320x240. This would be great for memory but the resolution is so bad that I can't see the monitor clearly.
So for roughly 20 minutes of recording a tutorial, with storage space being of some concern, I would have to go for 1280x720. This would equate to about 2 gigs of space for 20 minutes. This seems rather high since DVD movies are about 2-8 gig for 1.5-2 hours. Or am I comparing apples to oranges.
Do you guys have a better solution on what video settings I should use or maybe there's something that I haven't figured out yet?

first of all DVD has 720x480 (480p) resolution, less if it's wide screen, so Note 3 1280x720 (720p) will take more space since it has more data. Also compressing video on the fly is more difficult, since you have to do it in specific time, before you fill up buffer with following frames, so it's less efficient.
Now for solutions:
1. get micro SD card, they're really not that expensive, just make sure it's x10 speed. They even have 128GB albeit those are expensive.
2. recode video at higher compression rate later on your computer
3. resize the video from 720p to 480p on the computer since Note3 does not support 480p resolution, but it could be best balance between size and quality, but this could be tricky quality wise, since every time you uncompress and compress video you loose detail.

I would say: install screen recording software on your pc, that will give you the best quality.

[Q] Note 3 Camera - Slow Mothion Function - Original (real·time) Speed! -–-?

Hello, you surely already know about the 120fps-Recording of the Note 3. [TAGS TO THIS THREAD: SlowMo|SloMo|Record|Video|Speed]
Like (almost) any other Slow-Motion-Camera, there's something, that really disappoints me!
What disappoints me:
If you record a Slow·Mothion-Video, then the Video will be saved as Slow Motion too!
-Better: Save in Original Speed and in the Player you can slow down - and choose if the Sound keeps the pitch-level while speed adjustment.
IF i record 4 seconds @ 120 Fps, then i want to get a 4sec. Video with 120·FPS.
and not a 16 seconds-video with 30 fps with lost sound.
What i'd like: Save in Original Speed and Includes Sound while Recording!
But even worse: If you get asked to edit the video after that - INFORMATION WILL BE THROWN AWAY!
Well... Xperia Z2 includes the Sound and the WHOLE Scene but the Slown-Down parts
The not-slown-down parts will be saved at normal framerate, so information gets lost.#
The Output file has 30 Fps.
„An Example“ said:
Here's one good example -
IF i record one hour Slow-Motion at 100 Frames per Second, then i don't want 4 Hours with 25 Frames-per-Second in the Output-File.
The outputfle must have Sound and 100 Frames per Second and must be 3600 seconds long in this example!
Click to expand...
Click to collapse
Click to expand...
Click to collapse
But the manufacturers think, that all the people like the sucking method!
The sucking method example:
I record 10-Seconds in real-time at 480 fps.
Then the output file has a length of 2 Minutes and 40 Seconds with 30 fps.
Then the Output-File isn't in real time.
That does suck! This sucks!
I want output file with no information loss (full framerate) but at real time with REAL 480 fps.
Click to expand...
Click to collapse
What you'd probably think right now:
Just play the Video at a higher speed in the Video Player!
My Answer:
Oh, i'm soo lucky, that 60 fps at real time is possible! With sound!
I simply want an output file without information loss.
Now what you'd think:
Well, that not-realtime-video which is slown down does have ALL Frames!
My answer - Well, yes... but then in the Video-Specs
What i'd simply wish:
If i record a Video (example: 00:00:10, 96 fps) then i want an output file with the SAME SPECIIFICATIONS.
What i don't want:
If i record a Video (00:00:00:10, 96fps) then i get a Video with a Length of 40 Seconds and 24 Frames per Second.!
NOW DON'T SAY:
„Why is slow-motion called SLOW-Motion?
Because you want to get a Video with SLOW-Motion!“
Click to expand...
Click to collapse
Then my answer would(avtuallý ) be:
My Personal answer:„Well... ýes but this is what I want. And it is more pratique! The players display real-time-equivalent speeds (1.00x Playing Speed= Original RealTime-Equivalent Speed ) and a Higher Bitrate/REAL second would be maybe worse for devices with weaker processingPower but the filesize would be the same. (4x Higher bitrate but 4x shorter video. Why not 5x higher bitrate? Less detail-loss! (WooHooo!)) “

I Forgot to finish writing here!
Both Videos ([email protected]) and [email protected] both have ALL Frames.
But the RealTime-Equivalent Video with REAL 120 fps is simply better!
Well, it's got 4x higher bitrate but is also 4x shorter.
So the Quality will be approxmintly the same.
If you see a 50fps or 60fps Video (real time), then you'll see how awesome smoothly it is!
120fps at 720p ([email protected] 120/100fps for LUMIX FƵ1000, great!) has a little bit lower resuoloution but runs even more smoothly.
Which mode you choose depends on situration.
4k is for detailed moments if 24-30fps is smoot enough but 60fps for a little bit more movier moments...
120fps is useless because there's no sound and the output file is slown doen.
120fps would be useful in some sitouarations, if the output file would have a RealTime-Equivalen-Speed (1.00x Plaýback Speed ≜ 1x Realtime Speed) and also sound, in the Full Microphone-Quality of the device(can do.!).

Did you know... ?
In (the )most more Advanced Players (Windows and Android) you can slow down playing. 0.125x/12,5%/⅛ Playback speed are also ⅛ in REAL WORLD.

In the Sucking method:
4x or 8x Playback Speed= Original Speed in the Reality. And no sound. I hate that.
[Hide="Did you know - ?"]So did ýou know? : that you can slow down in more advanced players? And they show those REAL-TIME-EQUILEVANT speeds. 0,25x Playback Speed= 0.25x Real-Time-Eq. Speed! Better method!
And it's quite stupid to think, that everybody likes a slown-down output file - and even without sound (mutid). Muted sound=lost sound information in [umgebung] and 4x playback speed = 1x Speed in Real world? - „Oh no!“ But those manutfacturers think, that everybody likes it. What do you think of it? Simply post it![/HIDE]
So you just need to slow down inside of the player, to see all those small moves.

Is the method (that the Manufacturers use) [REALLÝ] BETTER?
...and WHAT is the Advantage of the method, that i don't like soo much for slow motion?
I don't think so- every player must have a Feature for Slow Down, Reverse Playback:laugh: and Ƶoom while Playing/Pause/Preview Frame. (Rotation is very Funny.)
And it must have a Feature to adjust sound mode at Speedup/Slow down! (Keep Original pitch or make it Lower/Higher at Slowdown/Speedup.)
And it may also would be a good idea to use te trick in the Média Players, which one the High-Advanced SmartTV's - „Calculating“ the Frame(s) between 2 Frames. (Works almost perfect for flowent running text ).

GSMArena said:
The slow motion clips might look cool on your iPhone, but they look quite disappointing on a TV or a monitor. Which reminds us of our other disappointment about the feature – when we tried to play those iPhone 5s slo-mo videos on a PC we found that unlike all previous slow motion-capable smartphones, the iPhone 5s actually encodes the video at 120 fps and your computer will play it on 120fps unless you explicitly force it to slow the video four times in order to achieve the desired slow-motion effect. It would have been way more natural the iPhone 5s to process the frames and output a standard 30fps video as most of the phones do, which doesn’t require special players and tools to play properly.

For example: VLC Always keeps x1.0, indipendant from Playback Speed. But MPC-HC► makes the Pitch-Level dependent from the Playback Speed (► x2.0 = ♫♪x2.0)
Pitch Level is Tone Height. aka Pitchbend.

No Sound and not Realtime.

I can't believe that the FƵ1000 and the 255 HS also have that issue.
But the SX50 HS and the RX100/3 are completly free of this issue .
...also, the S5 (not the Note 4) are able to adjust the Playback-Speed in the player...
and... duh, forgot what.
Have a nice day

Links and Info
The Canon IXUS 256 HS would be actually nice - it IS nice. (And also low noise at high iso and full resolution iSO6k)
...but it has this again.
Look here, many people also want AUDIO on Slow Motion.
Link 1
Link 2
Link 3,4,5
Link 6

One Advantage
If you want to see the Slow-Motion effect on a Friendly RT-Slow Motion (Output file is the Same as Sensor Records), you've got to slow down inside of the player to see the Slow-Motion effect. And also... not every player has this feature.
This is a big advantage of the Sucking Method but i think, that it's really the one and only advantage.

For those that have it. Quick 4K info..

Whats the 4K recording bitrate and hows it compared to other phones . Also, is there a 5 min limit like on my note4?
--Thx

I did a quick test and got 90MB for 15 seconds, around 6MB/s.
But, I wasn't sure if there was some way to stress the bitrate of the codec - bright scenes? dark scenes? high contrast? If anyone has any insight into which are the hardest scenes to compress I can repeat the experiment.
Or, is the codec somehow a constant rate codec (as in fixed rate MP3 vs variable rate)?

how about the time limit? how long can you record 4K?
I think 6/MB is average. I heard of people that root note 4 able to up the bitrate. Even if it is the same it still might look better then other phones with the same bitrate due to the lens and so forth. I think the main issue is going to be with the stabilization. OIS helps but I guess you can run it through adobe or some other program to get software to add to that. I wonder if I record in 1440 if the software will work for that.
