Need help for converting 3gp video format

Post by gyht69 »

Description of problem or question:

I am converting .3gp videos shot on a Nokia phone from 2010. The videos convert fine but the audio does not convert. I have tried different audio settings with the same results - the converted files have just a distorted audio sound. More info on this format below:

https://fileinfo.com/extension/3gp

I can import this into Mac's editing software iMovie and reexport from there with no issues except a far bigger file size. Would really like to use handbrake but need to know if this audio format is properly supported. Thanks

Steps to reproduce the problem (If Applicable):

HandBrake version (e.g., 1.0.0):

1.6.1 (2023012200)

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

MacOS Ventura


HandBrake Activity Log ***required*** (see How-to get an activity log)

Code: Select all

Wow, that's a very short clip. Would you mind sharing the source file somewhere?

I would think, encoding such videos only can make it worse.

I assume you cannot play the 3gp files natively? If it would be my video, I probably would have just re-encapsulated it in a MKV container, as the video and audio format should be playable on a computer.

Either way, if the audio doesn't decode correctly, we'd want a sample so we can fix it.

Dear All,
Thanks for your response. Yes, .3gp files can be played natively but I am sending these clips to other people via mobile and it does not play on some devices. I also want to convert these for future proofing. I can use an NLE to convert (iMovie, etc) but it does take more time and steps.

I've attached a link for another video: https://1drv.ms/v/s!AkV5JVFUe_lzhKFcpgk ... Q?e=Jbe0sg

The visual quality of the videos are fine after conversion. Just the audio.

Thanks for any advice.

Got the file, was able to reproduce the issue with both HandBrake and (correction: but not) ffplay (accidentally tested it on the output, my bad).

Let's see if we can get his fixed before 1.6.2 (no guarantees) :-)

Looks like it's fixed in git master; I think I may know which FFmpeg patch to backport, so it may make its way to 1.6.2 as well (otherwise, development snapshots will have the fix anyway).

Can you confirm that unlike 1.6.1, https://github.com/HandBrake/HandBrake-snapshots is not affected by the issue?
