Gameplay footage audio is really out of sync. How do I fix it?
« on: September 05, 2014, 09:21:18 pm »
Gameplay footage audio is really out of sync AFTER I take it into Adobe Premiere, and then Export it to H.264 .MP4 format. How do I fix it?

The audio of the recorded .avi is in sync and is fine, but if I take it into Adobe Premiere, do absolutely ZERO edits, and export it to H264 .MP4 format, the audio becomes out of sync.

Basically, as the footage goes on, the audio becomes more and more out of sync for some odd reason. This is VERY apparent during fight scenes & during conversations with NPCs. (Dragon Age 2)

Anyone have any ideas as to what I can do to fix this? I have over 1 hour's worth of footage that this is affecting.

Thank you.

I'm not familiar with this issue. Your LAME MP3 audio codec might be the issue.

Try recording with default PCM Audio Codec and check will you experience the same issue when you export the video through Adobe Premiere.

Agree, only thing i can think of is Decoding issues.
It's likely that the AVI file has non-zero delay positions, and that may perhaps not be supported. Somehow doubt this though (This would cause a fixed desync, not a gradual).

I have plenty of material here. Can be used in daily life, not really.

This could be due to Premiere Pro's problem with handling video files that have a variable FPS rate.
I notice this with h264 Streams inside mp4 containers from nvidia shadowplay too.

The simplest fix is to set dxtory to record at a constant frame rate (30, 25, 100, whatever). This obviously only works if dxtory records at the set frame rate, even if FPS in game fall below that value. (I only just aquired a license and am at work, I will fiddle around with it tonight)
To fix your already recorded files, just run them through handbrake.
Take an h264 preset, set it for a Q level with minimal quality loss and select a constant frame rate.

I had to do this for all the files for an XCOM The Bureau LP. Was a bit of a hassle, but I'm just glad someone found a workaround (which I shamelessly copied). :D
