Audio video sync - low framerate audio glitches

I'm working on a project that used to be created in Ventuz 6.3 and since I 'upgraded' it to ventuz 6.9.4 we're having a few audio issues.

It used to be that clips would be playing (on high systemload) and skipping frames, but audio kept playing without glitches. Somewhere along the line it seems that audio now stays in sync with video and as a result I get audio glitches - dupes, skips etc.

Is this somehting that can be configured somewhere? As the client has been ok with the slight video glitches that occurred. On my laptop stuf is worse as that machine just can't cope with the massive movies.

Hi Sander,

long time - no see!
Is audio coming from the movie clip or is this a separate file?

Best Regards
Karol

Yes it's been a while that I really played with Ventuz! But old habits die hard and even my muscle memory seems to trick all kinds of cool features I remember from way back when :-)

Audio is combined with the video clip. Actually too very similar clips are running and both have audio but in one it's been disabled in the properties. I used to have more smooth audio and glitchy (out of sync) videos (two videos didn't play in sync on my laptop) but now I see frames are still in sync but everytime my laptop cannot cope (and that happens quite often) the audio glitches too.

On the runtime environment I got a report they are experiencing 'echo''s' (didn't hear or see that myself (yet)) - the machines are probably taxed with the project too as I was noticing glitches with the big videos. (AMD Eyefinity 270* degree canvas)

Did something change in how AV sync is handled? And is that an optional setting that can be reverted? As audio glitches are way more noticable then the video glitches.

Thanks!
