new soundtrack sync issue
« on: February 19, 2020, 08:07:56 PM »
I'm trying to replace original audio track (because it's dubbed Russian onto French and not split) that is separate from a film.
The add goes OK, but I can't seem to get the sync right.
Source video is .avi @ 23.975
Source audio is ac3.
When I don't delay, sound is late by :02 (aka 2000ms).
When I delay by :02, sound is still off.
I'm watching the result, pre and post, with Plex.

Is there something I could try or am missing?

First of all, have you tried with the latest nightly? --> https://avidemux.org/nightly/osx_catalina/
Even if the latest macOS nightly is far from being current, a lot of changes have been added since the last release (2.7.4).

What codec does the video use? What container have you specified to mux video and audio into? Unless the video codec is some legacy divx / xvid, please don't use AVI as output container.

the 2.7.5 nightlys all crash upon launch.
I'm on High Sierra.
Though I assume by Catalina, this means the nightly is, in theory, compatible with Cat; and backwards as well.

codec 4CC is XVID.
I tried MP4, then .avi, then .mkv.

Could you please launch it in Terminal

Code: [Select]
/Applications/Avidemux_2.7.5.app/Contents/MacOS/Avidemux2.7
and post the error?

It might be backward-compatible, but not sure about it. You could build Avidemux yourself, this is not difficult on macOS. Basically, with Xcode and command line tools installed and Homebrew set up, you do

Code: [Select]
brew install git cmake nasm yasm qt xvid x264 x265 opus fdk-aac lame mad libass mp4v2 a52dec
git clone https://github.com/mean00/avidemux2.git
cd avidemux2
git submodule update --init --recursive
bash bootStrapOsx_Catalina.bash --with-system-libass --with-system-liba52 --with-system-libmad --with-system-libmp4v2

If the build succeeds, the app should be in the "installer" subdirectory. I assume that the Catalina build script should work on High Sierra as well.

(IMVHO Catalina is really awful, especially for Avidemux testing and development)

Please send a personal message then, CleanTalk is very prone for false positives, unfortunately, and completely not tunable for me.

(Clearing browser cache and / or changing IP address helps sometimes).

Ah, I see, the compatibility is indeed limited by

https://github.com/mean00/avidemux2/blob/master/bootStrapOsx_Catalina.bash#L49

to Catalina. I'll check whether a lower value for MACOSX_DEPLOYMENT_TARGET still works on Catalina and if it does, will ask the maintainer to refresh the macOS nightly. This may take a few of days though.

Please try and report back whether the new macOS nightly (200313) is capable of running on High Sierra. It was built with MACOSX_DEPLOYMENT_TARGET set to 10.13 which is High Sierra.

https://avidemux.org/nightly/osx_catalina/

Thank you.

private didn't change.
but as I use VPN most of the time.
As you prolly know, most of the time those IPs get bumped from many public forums.
Try to remember the exception here.
