[TIPS]A/V out of sync when compressing 720p videos

I'm sure you noticed that when you record a 720p/1080p video with a smartphone, the bitrate will be pretty high, in the 10-15Mbps area.
This is not really necessary if you watch the videos just on your smartphone or on a limited size LCD TV, and you can just recompress it using x264 codec at about 2Mbps without severe quality loss (unless it's a sport video).
However you'll notice severe audio video out-of-sync issues if you compress both audio and video tracks and DON'T CHOOSE MP4 (which is the default container for the videos recorded by the smartphone) as default container for your x264 video.
Furthermore, if you want to compress and then JOIN different videos, you have to compress them one by one and THEN join them, otherwise you'll notice glitches in the playback.
I tried with mkv and avi but I kept having sync issues, so I thought that it was worth to share this tip.

SUPER @ video conversion program
Have you tried a video conversion program called SUPER @? Here's its link:
http://www.erightsoft.com/SUPER.html
The program can be pretty intensive in terms of memory used but it usually does a great job for me and bitrates can be chosen for just any vid type you might want to save to. Usually, I turn off my internet connection prior to executing it (so it can't do an update check) and run it by itself.

Yep, I guess it's something similar to Wondershare Video Converter Ultimate, it's just that I prefer more control over encoding parameters (so I tend to use programs such as Avidemux)

You've probably already thought of this but you can load your video in virtualdubmod and have it change framerate so video and audio match perfectly.
No re encoding needed and even on large files it takes less than a minute or two.
If you find virtualdubmod won't recognise the video you can download a suitable vfw codec and it should then.

The problem is that vdubmod won't help, because framerate is not constant and it varies from some 19 to 30fps, at least on Vibrant.
In a lot of cases the fps number gets lost during encoding (and you'll obtain a video which has a constant framerate of 29.97fps), because softwares such as Avidemux doesn't have an option to leave the FPS untouched (or at least it seems that the fps number gets lost if you want to use MKV as container).

I've used it in similar situations so it might be worth a try as it doesn't need a constant framerate, it looks at the audio length then adjusts video framerate to match.
If it is just a problem created while actually recording, ie if the video itself records at varying framerates it would suggest that it can't write to storage quick enough and is dropping frames.
In that case you would need to record in lower resolution or perhaps find a replacement camera application and see if that could fix your problem as sometimes default apps are not all that good.
It also makes a difference if you can close un needed background apps to free ram if low on memory. That can cause frames to drop as well.

Actually it seems that the framerate is lower in case of dark scenes, which seems to be a behaviour found on other phones. I'm writing on the internal storage and I always kill everything before taking a video, so I gotta try another Camera app and see if anything changes.
I'll also take a look at that interesting vdubmod feature, I didn't know it.
Thanks.

Is there a setting where you can change encoding parameters of your x264 on your phone?
On a pc the codec has a feature that can compress more data per frame in darker areas, on a phone I don't know if that is active or not but might be worth checking. Sorry I couldn't help more but hope you find a solution.

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

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

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".

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...

[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.

Video not recording in HD

I am currently running stock unrooted ROM 32.1.A.1.185 with unlocked bootloader. The video is currently to record in Full HD at 30 fps. When I inspect the details it says 1920x1080 but the file size does not look right. A 7 second video is around 15 MB or so. When I upload the video to Facebook and YouTube it's not recognised as HD. YouTube reports the size as 360p!
Has anyone else had this issue? I have trawled around as well as I could and found nothing reported. Do I just have a faulty phone?
Thanks,
D.
Further findings:
If I upload a video by recording it through the FB app then the HD option is available when viewing. If I record the video outside FB, then share it through the FB app, the HD option is not available when viewing! Go figure...

thats very odd and I dont know any solution aside to reflash the stock firmware of your device
I havent tried with youtube but anywhere where ive uploaded a video recorded from my phone it shows as 1080p

Very strange indeed. It seems to be weirdly network connection dependent. If I watch the same YouTube video on my desktop, on wired network, the 1080p option is available. If I watch it on the same network, but WiFi, it's only showing 480p!

Very odd im not sure what could be causing this but i know of some similar odd issues where youtube wouldent load on wifi for me some time ago, this was with my xperia z2 and a reflash and reset of the device solved this.

How do you change video frame rate to 60fps.

OK, now I feel like a newb but this is my first Pixel device and the Google camera seems simple enough but I can't find how to set my video framerate to 1080p 60fps. I have it on 1080p and the only options I can find are on the top bar with color temp and flash and all it gives me is Auto and 30fps. Auto seems to go anywhere between 120 and 30 fps, I can't figure out the logic behind how it chooses. I really just want to lock it to 60fps for 1080p. Can someone help me out?

Turn off video image stabilization?

I turned off IS and am still not seeing it, I tried 720p too and nothing but auto and 30fps. Open Camera and Filmic both give me 60fps.

I'm thinking anything over 30 fps is "slow motion" only. Still looking around myself b/c I'd love the 240 fps for videoing my golf swing

Woah. This is a near deal breaker here. I can't seem to find 60fps on my $850 phone.
Update I found the place where you set the framerate, but unlike the Pixel 2 (which shows 30 and 60), the Pixel 3 only shows Auto or 30. W. T. F. This "auto" icon is located in the lower left when in video mode.

For what it's worth, I've gotten near the proper framerate with 3rd party apps. Both Open Camera (free) and Filmic Pro (paid) hit 59.667 on 60fps mode. The proper framerate is 59.94 (60,000/1001). Filmic Pro can do an exact even 60fps too if you force the framerate. I may try to gen some answers from Google directly if I don't figure this out over the weekend.

I tried open Camera, and it looks like 30fps when I force 60fps. It just says about 30.095, Min 22.222 and max 43.103 in Media Info. This is fail.

Can't find it myself! help

Was wondering the same thing. Selecting info on a recorded video doesn't show framerate either.

Automatic FPS Switching
First, a new option to automatically switch FPS during video recording has been added. According to a Product Manager that we spoke to at the event, people have trouble deciding what the best framerate is before recording a video. This new feature lets the Google Camera app decide what framerate to record at – either 30 or 60 fps – depending on what’s on screen. The feature can even switch framerates in the middle of a recording. It doesn’t work with 4K videos, though.

Hold the phone horizontal and select video mode. On the lower left corner you will see a little icon "A". Touch this icon and you will see "Auto" or "30fps".

Great, so 30fps is working as intended on an $850 phone. Thanks for finding this gem. Glad I don't have to wait 6 months to a year for this quote from Google to find out it essentially will never be fixed. Hopefully they don't regress on the Pixel 2, because this isn't a improvement in my book. How about Auto, 24, 30, 50, 60 option on an $850 phone?

This is not acceptable.
I want to be able to lock it to 60fps, not to leave Google device the frame rate for me.
Guys, we need to send feedbacks via the Camera app and try to involve the media (@madebygoogle on Twitter).
That's the only thing we can do to hope they'll release an update enabling 60fps selection.

I just confirmed on their support chat that there is no option for 60fps, like we didn't already figure that out. They suggested going to 'settings -> about phone -> send feedback about this device' and sending feedback that way. I am already posting what I can on social media as well. Wish we could get this in the front page of xda.

I just used Open Cam set to 60fps and the Google Cam on auto to record the same scene and I must admit that they look identical. I cannot see the difference with my naked eye.

This is exactly my observation. Which means, this could be a limit of the new hardware and/or part of the Visual Core stuff which might be a harder thing to fix. We shall see how Google responds.
I think it will be "working as intended" or the hardware is limited to auto, because (insert some sort of white wash excuse). I would prefer darker video of 60 fps over brighter 30fps variable frame rate hogwash.

So today at my son's baseball game I used open Cam locked in at 60fps and goggle at 1080 auto and the open Cam video looks choppy and looks like it skipped frames. The Google Cam video looks very smooth like 60fps does. So I'm gonna say that Google Cam does a dang good job of chosing the best fps.

Video recording is an afterthought on the Pixel series. Stabilization is top tier, but everything else (image quality, audio quality, etc) takes a back seat. I'm actually not upset since I rarely ever record videos, and when I do, they are short clips at home that have ZERO production value. I'd be willing to be 95% of consumers are the same way.
Heck, have you noticed how every amateur video that goes viral on the news is shot in portrait mode and not landscape?! #PetPeve
