[MOD] 2.3.6/7 Video Recording audio improvement -- WIP

Hi everyone
when you record a video on your original SGS 4G camera, your audio sampling is :
66 kbps bit rate.
16 KHz sample rate.
which is pretty lame...
If you ever tried to record live shows or concerts, you probably noticed audio is awful on recorded video...
Introducing Video Recording audio improvement MOD
found and very well explained by rafalense (http://forum.xda-developers.com/showpost.php?p=10980448&postcount=268).
Performed on SGS 4G camera by me. So, now recorded audio sampling is :
118 kbps bit rate.
32 KHz sample rate.
file size change is barely noticed.
Still camera is not modified.
I took, as a basis, the Team Acid modified camera - done by DSexton702.
So it is capable of taking pictures when battery is low and also by using the power button.
This is still in beta as :
1. Currently Audio-Video is out of sync. I need to check if this can be fixed by changing Video sampling rate....
In the meanwhile, you can fix this on PC very easily.
2. This mod does not use the media profile xml for greater video frame rate.
I actually put the original file back. I found the result to be not supported by all players and having some side effects like visual waves (and much larger file size).
3. Actually I examined DSexton702 media profile and it defines some various audio sample rates but always create 16KHz at the end.
If someone here has the knowledge in A/V synchronization or a good setup that works - please let me know so i will fix it.
Thanks.

Awesome work! Thanks.

Glad to have u aboard thanks for this man this is well needed!!!!!

Now having AntonX kernel supporting Vodoo Sound - I will test audio HiFi record option enabled on video recording and update.

Would love to see this become final. You certainly are right about the audio during concert recording. All we hear is pure bass... Thank you for working on a much needed video recording mod.

Yeah.. would be awesome.
Thanks for the work, itzik2sh.

Edit : guys working with Voodoo sound (with supporting kernel)
need to run the Voodoo sound app and choose 'Recording Preset' - then change default to 'Loud environment - with DRC'
This should improve the recording level of loud shows.

Hi
Did anyone here test this MOD with live concert recording ?
If it doesn't help than I'll drop all further work.
I thought this problem is SGS 4G unique, but it turns out it exists on all Sammy phones,
even Nexus and SGS 2. See this bounty thread for SGS 2 :
http://forum.xda-developers.com/showthread.php?t=1172048
and this :
http://forum.xda-developers.com/showthread.php?t=896826
I'll try to ask AntonX to take a look or maybe ask supercurio on kernel implementation...
I also tried installing LGCamera from the market, which supposingly has an audio gain control, but it fails to launch and I had to uninstall it.

Nice improvement

After voodoo digital recording, video and audio are repacked and converted to the device analog sampling rates, that this tweak changes (but also unsyncs)...
So if you have the time and effort, I'd appreciate if you share your experience with us all.

Bad sound in videos w/ N5

I like recording videos when I'm at the disco, or a music festival, but the sound is awful
It's probably because of the too loud sound, I think that the bass make that disgusting noise
Do you know of any solution to this?
Thank you!

You can't solve anything, you must accept the fact. It is quite impossibile to record a live concert, either it will be in disco or a metal one. Even with professional cameras the sound will be bad. In these circumstances you must record the sound directly from the mixer, and you should use the camera/phone only for the video. Then you mix sound and video, and the final result is a good thing

Very Bad audio quality in video recording

Hello guys First of all it's my first post in the nexus 5 group (i've did a pre-search) and i contact you with this problem
Last night i went out with friends at a pool party and used my nexus 5 for recording some videos from the stage. The music wasn't to loud, just like normal club music, in open space. Today when i took a look on the video i got scared...the sound quality is insanely BAD !. It's like the phone is set to +100 gain in the microphone... I tried normalizing audio in premier pro but with no chance. So i ask you guys, do you know any solution on how i can repair the problem. The best audio quality i had in recording videos in club (audio especially) was with my Nokia E51 that had the best mics i can find one a phone...
so here is a comparison:
In club music (closed space) shot with my Htc One S (no dual mic or things like that) -> https://www.facebook.com/photo.php?v=487777791348118&set=vb.100003477036350&type=3&theater
in club music (closed space) shot with my Nokia E51 (a 5-6 years phone that still records audio crispy clear for a phone ! - don't look at video quality) -> https://www.facebook.com/photo.php?v=247706518688581&set=vb.100003477036350&type=3&theater
last night with my nexus 5 ->https://www.dropbox.com/s/3vtisokit5ontwl/VID_20140727_032412.mp4
All the link are so you guys can see that exact problem that i have. I want to repair it, if it is possible in the stock rom (with a app) or if i need to install a custom rom, what is the best rom that resolves my problem and has best performance .
Thank you in advance !

I have exactly the same problem. Tried recording at a couple of indoor parties(so a little louder than your situation. Couldn't recognize any music when playing the video's afterwards. Terrible quality
Sent from my Nexus 5 using XDA Premium 4 mobile app

Partial fix - i think
Ok so last night i got an app from play store called microphone that has a setting on the mic called mic gain. it was set to +32 dB....overgain ! so i set it to 0 and did some recording in the house with my audio system on a high volume and afterwards put the phone next to the speaker and seem that it records decent . but i think it is a problem related to software settings... will keep you updated on what i found

Sounds awesome. Thanks for your effords
Sent from my Nexus 5 using XDA Premium 4 mobile app

Problem solved?
I can't post links so if anyone wanna fix this or just post the links from my post that would be great, thank you.
So I've found a solution, or at least a temporary one
Get the camera app called Lgcamera. In this app you can manually set your audio settings.
Set it to AAC and set the stereo option to On (this did it for me atleast).
/store/apps/details?id=rubberbigpepper.lgCamera&hl=sv
I made a little video about it since I couldn't find this solution before, hope it helps!
/watch?v=RVWcE3dQoMk
Please help spread the video on forums where this issue is discussed so more people (and perhaps even Google?) can record without that awful noise reduction/cancellation! If enough people complain then they will probably (hopefully) implement these settings in the "Google Camera" app!

Thanks for the video! This is the video.

BE CAREFULL though with LGCamera, because I found that no matter what you choose in settings, fullHD (1024p) videos are ALWAYS recorded with 15 frames per second only (vs 30 as normal), making the videos look very choppy. So I deinstalled LGCamera again. Otherwise great app.
But I found a good substitute, it called Open Camera, link to the (free) app and also a possible video mic fix (reduces mic gain).

Hmm, strange. I do not have that problem. I record with 30FPS without any problems. Maybe something is wrong in the settings? Have you tried changing the video format around? The app is not that great but it does the job for now, atleast for me.
Edit:
I noticed that the front camera is not that great in Lgcamera, but the back I have no problems with. I recorded a video on my instagram if anyone wanna check it out. I'm still changing the bit values around hoping it will sound even better.
Speakers are "semi-loud" and i recommend watching the video in your phone or atleast lowering the bass if you're watching it with "real speakers".
instagram.com/p/rCDsh5xX9C/?modal=true
Here are my settings for this particular video:
Back camera
1920x1080
H.264
Vid Bitrate 17mbit
Vid framerate 30
AAC
44100 Samplerate
128000 Bitrate (unsure of what value is best here)
Stereo OFF

Ok thanks, I might give it another try... Open Camera works well for me, though.
Did you check the actual framerate of your resulting video with a tool like mediainfo or VLC Player codec Info?
Nice guitar work btw

Open Camera works too, but I still get the audio artifacts when recording with a backing track. I get those in LG too, just not as much. Lg is in no way perfect, but the sample and bit rate allows a bit more customization if you ask me.
I'll upload one with OC when I get home! And thanks
By the way, what settings did you use in Open Camera? Or did you just lower the gain?

higher bitrate = better quality/higher filesize :good:

HUUUGE discovery today!
Update your LG-camera, go to settings and set audio to "voice communication" = headset. You can now record with your headset, see my instagram @Callemusicman for results!
It completely removes the noise cancellation!!

Isn't there any other solution? Because if i use, for example, Instagram, the sound is still very bad... so this LG app isn't usefull for recording with Instagram or other apps...

🎥 A better Slow Motion Recording Experience►

Hello, everyone‼:laugh:
Thank you for reading this.
Almost any phone of today has a Slow-Motion / High-Framerate feature.
Well, i've got nothing agianst it but there's something about it that truly sucks.
Here's my old thread about this.
The Bad method:
You Record: 00H:00M:10s@240fps (Resolution doesn't matter)
You get a Video with 80 Seconds @ 30fps
...and Muted Audio ♫♪
So that ►x1.0 isn't realtime!
Well, the iPhones record in realtime, but they can only record for 20 Seconds (real time equilevant)
kryz70fr said:
With the iPhone 5S camera software, you can edit your video to active slowmotion or not on the timeline ... how to do this with the Note 3?
Click to expand...
Click to collapse
Yes, you're right!
...but the Smartphones which use the sucking method of taking Slow-Motion Videos encode the output file being Slown Down.
The one and only advantage of this method, is for Media-Players which haven't got a Fast/Slow motion playback mode so that ►x1.0 makes the Slow Motion Effect Visible.
But i'd like to have ►x1.0 is Realtime-Equivalent!
So the Correct way in my opinion [IMO] is this:
If you Record 00:00:[email protected]
The Output File must be also 00:00:10 encoded at 204FPS and with ♪♫ Audio from ALL Microphones of the Phone!
Also some other Devices use the WRONG Method:
Lumix FƵ1000 - Great Camera but Slow Motion Feature uses WRONG WAY.
Canon IXUS 255 HS
But those Devices use a Good Method!
Sony RX100/3
Canon Powershot 510HS and 50HS
Sony FDR-AX100
Samsung NX1 (i think)
Example Videos ? :
Good
Only 720p BUT
XAVCS
And Audio
And Realtime
BAD
1080p but...
No XAVCS
Not Realtime
Muted Audio
Sucks
All Example Videos are taken by DKamera.dé!
Feel free posting your opinion! :laugh:
All the best Have a good and nice day ...

High Framerate Recording
Has anybody an Opinion about this?
There are many users who want Audio on Slow-Motion.
That, what i described there ↑↑↑, also covers this.
I'd be thankful for some feedback on my suggestion.
It's also nice, if every media player in the world has following features:
Speed Up / Slow Down
If adjust speed, enable/disable adjusting Sound Pitch
...so that 120FPS with output file encoded to 30FPS and muted sound is not there anymore
With ►x1.0 i mean Original Playback Speed of the Output File.
I'd always like to have 1.0x Playback Speed being Realtime-equivalent and Sound from every microphone that the device has (not just 2), independent from the Video's Framarate . (And no time limit until the Deices Battery/Storage runs out)
Example: Samsung's Galaxy Note 3 and Note 4 have 3 Microphones. But they do only use them all for the Sound-Memo and only 2 for video recording. They also record Slow-Motion the wrong way
Feel free giving your Feedback

Slow Motion - Redefined :·) (•:
I'd always like the Output file being always RealTime ►x1.0
That means, that i'd always like to get an Output File to be Real-Time-equivalent at x1.0 Playback Speed.
►1.0 to be Real Time Speed
And surely Audio from all Microphones of the device
(In FLAC Format, 1.6 Mbit/S )
(See Video04.Mp4✔)

Just like [email protected]
If i record 00:00:[email protected] then i'd also like to have an output file with 0:00:[email protected]FPS with sound.
...and not 00:00:[email protected]FPS without sound.
It feels like Recording REAL [email protected]FPS, i don't know how to explain.
Just like normal Video Recording but with a Higher Framerate - not additionally encoded to be slown down so that Original ►x1.0 Playback Speed is 0.25x Real Time Speed or 0.125x.
And also see this
Scroll down to see what i mean.

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.

They've got another Opinion. But their described opinion is caused by the only advantage of the sucking way to take Slow-Motion Videos.
Here’s hoping Apple fixes this promptly with an update – it certainly can’t be that hard.

I hope not so lol

Sensor output / Output File
The Output File should have the same framerate, as the Sensor is Capturing.
(Exceptionally HDR-Video. HDR Video needs a Higher Framerate/Sensor Speed but the Outputfile is still Realtime at ►x1.0 )

But yes, it will be very useful :laugh:
Many Smartphone Manufacturers write in their User Manuals, that Slow Motion Recording with Audio {Sound} Recording is not possible.
So why don't manufacturers simply use the method for Slow Motion Videos that i Described?
Maybe it's just because of the „One and Only advantge of the Sucking way to take Slow Motion Videos:“
Not every player has an Adjustable Playback Speed--.....
The Galaxy K Ƶooom has also a Menu Option for PlayBack Speed for the Ouptut File.
But you only can use the 120FPS-Mode @ ¼ or ⅛ Speed for Output File, but i'd prefer it always to be x1.
I'd like 1x Playback Speed to be Real-Time Equilevant.
Accordingly, Every Player should have a Manually Settable Playback Speed, Sound Pinch, Reverse and Recording Feature.
VLC Media Player has ¾ it all - exceptionally the Reverse◄ Playback Feature.
If manufacturers fix this slow motion problem, have fun

This iOS-App uses Optical Flow.
I hope this app also uses ?▶► Real Slow Motion...
If you REALLY want the Output file to be not ►1.o Realtime, then you can convert it after recording it into a second file.
There are Programs to do that.

There's a very high Request on Slow Motion-Audio and being able to adjust the Playback Speed in the Media Player.
http://forums.androidcentral.com/samsung-galaxy-note-4/464112-slow-motion-video-sound.html
I also don't understand, why manufacturers use the Way for taking Slow Motion Videos that i mentioned, because the other frequent way sucks.
Isn't there an app, which can record slow-motion videos the way i mentioned?
However, the iPhones only use Mono-Audio for any kind of Video-Recording. Horrible.
Sony:
Their Cameras (RX100 and FDR-AX100E etc.) record slow Motion the Proper Way. Congratiulations!
But their Smartphones only allow editing before saving - once saved, you can't adjust any speeds anymore.
Canon:
Newer models like SX50 HS and 510 HS use the right way - even for 240 fps - no specific time limit!. Respect!
But the beautiful SX255 HS also sucks recording them - 120 and 240 fps. And there's a limit of 20 Seconds (in Real-Time.)
Conclusion:
There are many - also free Video-Editing Programs for adjust the speed and Sound-Pitch (Pitchbend) of vidéos - so there's (almost) no reason for the (i call it the sucking way) of recording slow motion videos. (Only reason is the missing Playback Speed Pitch in many Media Players. S5+ aka S5 LTE A had it - from x0.5 up to x1.5 Playback Speed - even for 4k-Videos up to 61.2 mBit/s Bitrate!)
And also - setting playback is a small additional step before enjoying the Motion but if this step is too much, you're lazy.

Finally, in Slow motion mode the camera goes back up to 48Mbps but is now shooting 720p @ 120fps. Videos are actually recorded at 120fps, but you can edit them on the phone - trim beginning and end and choose between half, quarter and eighth playback speed. Here's how it looks when we drop to 30fps (playing at a quarter of real time speed).

I hope the Slow Motion also includes Audio.

Confirmed:
The S6 records Slow Motion WITH Audio and Realtime - like iPhone and SX50 and 510 HS and also RX100m3 (aka RX100 III)

GSMAréna
I was reading a Review on GSMArena.
Then i saw this:
A note about formats - the iPhone records and saves 720p videos with 240fps framerate so you'll need to either edit them on the phone to create the slowdown effect or use a video editor on your computer, just copying them would only get you an extra smooth normal speed video. The Galaxy Alpha videos are slowed down to 30fps so the slow motion is easy to share. There's an option to slow the videos down to 15fps, which matches the iPhones 8x slowdown but the result isn't as smooth

With the Galaxy S6, Samsung finally goes the Right way, because you can Export a Version of your Video, that is actually Edited and Costumized yourself, to share or so...
It's always recomennded to keep the Original Slow Motion Video File with the Audio and the Real-Time.
The Galaxy S6 has no MicroSD-Card, no Changable battery, etc........
But in Slow Motion, the Galaxy S6 is finally the right thing.
I mentioned the Galaxy S6-Disadvantages right here.
The FDR-AX100E also uses the right way.

For Galaxy S6 users (very rare):
Too bad, that so many older phones cam't set the playback speed in the mediaplayer, so if there's trouble, sharing your high-framerate-videos, you can edit the parts with the lower playback speed and export the shareable video, and keep the original real-time HFR Clip.
That's exactly, what i wish, every manufactueres do.
Simply make a Video Editor and Set Playback Speed, instead of recording the HFR Video the wrong "sucking" way.....

Treat like normal
I just like this type of recording the videos at a high framerate, because it treats Video Recording with a high fromerate as normal video recording. Just with a higher framerate.
Many devices have the ability to treat 1080p with 60 fps as normal video recording.

I was wondering if there's a posibility to record in slow-mo with my K900...

[Q] LgCamera App bad quality video on Samsung S4

Hey everyone, I have a stock Samsung S4 that I like recording concert videos on.
I had a real big issue with the audio. I might have that fixed with BootlegMic. I have also installed LgCamera in hopes of finding a fixed focus for my video. I found that this app did let me use an external mic that my stock app did not, but I cannot seem to get a decent quality video from it at all
I have tried changing video resolution, video encoder, video bitrates, and file formats. Every conceivable combination that's possible, (I realize any video res past 1920 X 1080 is not supported), but cannot get any video quality even close to the stock video app.
Is there anyone with experience with this problem that can help me get it sorted out?
Thx. Jerry.

This may be late
This may be a late reply, but just in case any one else happens upon this thread, it might be worth looking at Open Camera app. Lots of tweakable settings, fixed focus, exposure lock, external mic, etc.
BTW, I just put together a bootlegMIC and it is fantastic.
