R2 generic UK video rec - XPERIA X1 General

Does the new FW improve the quality of sound when recording video?
As I posted long time ago and never get any solution - the sound of the video is always strangely deformed,
WHILE when recording a sound note - it's fine!!!
Is it dependend on any setting OR the fact of storing video on memory card directly?

I actually never had this problem. What ROM are you using? I don't think it's caused by storing it on the storage card.. I mean, how the hell would that alter sound quality?
Try messing about with the settings a bit and also check what apps you installed, perhaps some codec got messed up a bit?

Haven't tested it, but, I would imagine that the bitrate used when recording video (128 kbps ?) is far inferior to the bitrate used while just recording audio only (>1000 kbps ?). Bitrate alone makes a big difference in sound quality.

Hmm
I havn't used it on older ROMs but hae taken quite a few vids of a robot I have been building over hte last few days and it has been fine, although the sound was mostly of myself and my team laughing and shouting, even the very loud sounds didn't clip or anything.

Thanks for reply.

Wizard + A2DP + QVGA Video = Slow

Hi ho
Yesterday I upgraded to the Mr. Clean latest ROM. (Nice ROM, fast boot time)
To celebrate my new A2DP goodness I bought a Blueant X5 headset which is offered by a company out of Melbourne, Australia where I live: http://www.blueant.com.au/x5_stereo_bluetooth_headset_headphones_a2dp.htm
I got it all paired and working fine, however when I try to play video in TCPMP which I encoded in PocketDivxEncoder, it's drops frames everywhere and the audio is out of sync. Benchmark shows like 17fps.
If I overclock using OmapClock to 216mhz (the highest I can go and stay stable) then it does improve the video somewhat.
I've also noticed it lags if you multitask while playing an mp3. I haven't tried any games yet but it would really suck if they slowdown too. I can live with the lag when playing audio, but not being able to watch video sort of defeats the purpose of getting headsets for me.
Does anyone know is this just a limitation of the KJAM's speed and that's it, or is there any way I can get the video to work properly, maybe there is a TCPMP expert who can give me some settings to make it run faster, because besides from the slowness I really love these headsets and would hate to have to return them.
Thanks
In my Case, I didn't get any lag by watching Video or hearing music files, I didn't OCed my device, I use the same program (TCPMP) to watch the video, and the same encoder program as you. I don't do anything special when I encode my videos, just the button and done.
It looks like you may have some applications running in your devic which cause this lags and make it runs slow. I am sorry if I wasn't that much help, but I thought maybe my post will give you a light.
BTW my device is Qtek 9100 , and I use the last Qtek Rom.
be careful what videos you try and play...attach the video so we can test the same thing. Make sure it's a low bitrate and QVGA resolution of course.

Mic recording distortion, due to hardware auto gain

One picture is worth a thousand words
Recorded with Tapemachine. Same conditions, same audio source, same settings... The only difference is hardware autogain control enabled on first sample, and disabled on the second one
How to disable it during video recording? No idea yet
that's a good improvement,maybe supercurio knows how to do it.that would be awesome for a good video recordings.
At least we now know the problem. Very good work.
Hmm i am really waithing for this fix. recording is HD is quite cool and good quality but its useless because the sound always go's bad because its recorded to loud.
New info:
AudioHardwareInterface: AudioHardwareBase::setParamenters(downgain=0)
That's how Tapemachine switch off hardware auto-gain
And auto-gain off seems only to work with mic set to front (AudioSource: VOICE_RECOGNITION)
Thanks to aLogcat app

hohoho. Now we just need someone with the knowledge to do that. Thanks rafalense for find out this
Don't forget that it needs those settings to be optimised for audio calls. Most likely, with theses settings, while in call, the audio will catch more of the surrounding than the vocal itself.`
So the best way for this to works would be to make an apps that does the command then goes dormant. Then you can record whatever and, when done, disable and close the dormant app (kinda like TrackerBooster)
BTW, don't forget that you're recording with a crappy built in microphone from a smartphone. I'll try to do the same with an external microphone to see.
I own both the Galaxy S and the Samsung Wave s8500.... And, i gotta say, that the Wave has MUCH better sound when recording video at 720p + Its much better synced with the actual video... Maybe you could look at the Wave and how i manages sound? It has the Bada OS (unfortunately)
Hi !
That's something I'll fix soon using hardware auto-gain.
For now I'm working on a jitter issue and the gain is the next one in the TODO list
As the jitter one is quite difficult I cannot give ETA yet

Thanks a lot, supercurio, without you, our galaxy wouldn't be as good as it is.
any updates on this item yet? this would make recording video's so much better.
Try this kernel, mic gain issue seems to be solved, plus other sound improvements:

Great efforts by the members of xda, REALLY.
The idiots at Sam**** should have sorted this out though.

video bitrate is already quite high but higher audio bitrate might be a good improvement
Hardware is able to record @48000 and around 256Kbps, but video and audio are out-of-sync
My guess, something coded wrong in the driver, so lets see if voodoo sound new kernel fixes it, and then we will record hd video with hd audio as well
A did a test for you minutes ago, check audio info:

why do you think this fixes it.. from my readings that kernel does not muck with video recording rates or microphone gain...
Hardcores K12L?
Check yourself. I did, and mic distortion is reduced considerably

I would recommend trying 44100Hz.

Also possible:
16000 - 22050 - 24000 - 32000 - 44100 - 48000 tested
How can you get the camera app to record at 44.1KHz?
Edit: Got it. Weird though, even though it's 44.1KHz, the cutoff frequency is 12.0KHz instead of 22.050KHz. Not much improvement over 8KHz cutoff, but better than nothing.

HD2 720P recording and the Noise in Phone7

I have been playing around with my HD2 on Phone 7 for the last few days and i am super pleased with the overall performance stability and user comfort it brings. Only drawback i have currently is that the market is not working but i think i farked up somewhere along the line there with the activation and registration.
Only one issue remains and that is the recording of video in 720P. The sound is to loud it seems and there is a big HISS covering all other sound. Now i was wondering what this sound could be seeing i recorded in a silent room (true silent room for hearing testing) and still the hissing was in the background. So while recording i put my HD2 to my ears and behold the hissing sound is the back speaker emitting static. I have no idea how to fix this seeing i am not an DEV.
But seeing the clutter of posts in the general tread i started this one. Can anyone confirm this behavior on their HD2 running Phone 7 ?

Hi Guys,
please note that though the option says 720P the quality that is captured isnt' 720P.

um buddy....yea it is. check your file props
is there hissing on the computer when you play it as well?
or isit just windwos phone being too loud?

The phone itself is emitting the sound while recording. The second you start the recorder it starts to hiss. And yes the hissing is there when you play back the video. And YES it is 720P i recorded video and checked its auto focus is a tad laggy but it works.
I can confirm both, that it's 720p and the noise in the background.
I have a few solutions in mind, I will try them and post back here so soon. As this noise is so frustrating !
I didnt find any unusual hiss noise. Only thing I found was wind noise, and Im cool with that. THe audio is very very clear in my honest opinion.
i didn't find any hiss either
in fact my phone was rather silent when recording!
although i have changed the maxdbatten to 60 and ui vol to 50
my volume setting was at five
and i listened to it back, and the music i "recorded" was very clear
infact you could hear my computer fans!
...
When i playback the video on my computer, there's no hissing sound. On the phone i hear hissing sound when playing any 720p video, so it has to be something with the format itself.
For the ppl who reply there is no hiss or static sound in the background or at all can you try and confirm the back speaker of the HD2 makes no sound either in video recording modus ?
I found video recorded are a bit yellow. look my own video test at http://youtu.be/rDGcYVOOkbY. Weather was foggy not so clear.

I've just given it a try and I certainly don't have any hissing noises during recording or playback.
noise
I am suffering from this static noise too. And yes, it is definitely eminating from the back of the phone. Tried different rom versions, the noise stays the same. I would appreciate if someone would share the solution with me.
Hiss
Here too !!!

Sound/bass recording quality > worst than SGS 2

Today I realized that the phone don't have any bass response at all when you record a video. You can put the phone right behind the speaker and it won't record any bass... but if you use the voice recording app, it does recognice bass.
Like this video i've found in the internet:
There are any way to deactivate the stereo recording on videos?

Old news, there's a whole topic on this already with like 200 post.
Supercurio is aware of the problem and is already working on a solution to be released with his VooDoo sound and color.
delete it, i've found a lot of threads like this .- Sry

Audio crackling in video

Hi just hoping someone has a solution for this. Notice that if I move with the device I get a terrible hiss or crackle in the audio. This is also noticeable if there is slight wind. Any way to reduce Mic gain or other ways to improve audio in videos. Super disappointed.
Thanks!

I wonder if it is the same problem I'm having, I just bought the phone and don't even have the right size sim yet to test audio in calls but when I recorded a video with the camera it has horrible static throughout. Even recording a silent room.
The only other test I could do of the mic was the voice recorder which worked fine.
I really need to know what is up before I pay to sim unlock it and swap my sim for the right size.
