While recording Battlefield 3, in "Games and Applications" mode, audio is synchronised with the video at the start but gradually desynchronises with video more and more over time. Has anyone come up against this problem and, more importantly, does anyone know of a fix for this issue?

This was previous versions problem. Do you use latest Action! version (1.9.1)?

Yes. Infact it only seemed to occur after I upgraded.

I'm about to uninstall out of frustration. I almost bought this program.

How long do you need to record to see the audio/video desync? And can you estimate a difference in seconds or miliseconds?
We have run about 12h tests (also with bf) with perfect a/v sync as a result.

Did you try to export recording to see if it is desynced in exported file too?
What software do you use for recording playback?

Can you provide us your video recording tab settings?

The desync begins roughly 5 minutes in and it's the game sound that suffers. The difference gets progressively worse over time so what starts out as a 1 second difference at 5 minutes into the video will turn into a 3 seconds difference 20 minutes into the video.

I believe I exported it, I can't remember. I'll do another test recording and make sure I export this time.
I use Media Player Classic v1.6.3.5818 (2320902) to play back video. I also run the exported video through FFMPEG to make sure it doesn't crash Adobe Premiere before importing it into that. I should note that FFMPEG has never created this issue on any other videos.

I did another test recording and uploaded it for you guys.

Looks like I'll be sticking with FRAPS then.

Do you experience this a/v sync problem with all games or only with bf3?

We are investigating this but cannot reproduce problem in our labs so far.
Will keep this thread updated if we have any news about problem.

I'm afraid I haven't tried it with anything else. I don't need it with anything else.

I got some desync audio too while recording Trine 2 for my website, it happens also in other games, but in this one it's more noticeable as I recorded files of 20 minutes.

It seems synchronized while playing the Action! AVI files, but when I encode it with AviSynth scripts in VirtualDub, it gets delayed (500ms) at start and synchronized at the end.

Maybe it is tied to the playback codec reporting wrong timecodes or frequencies for the audio ?

I'll try some audio export to compare it to the original AVI file.
