Out of Sync audio on older projects.

Hi.

I'm finding on opening old projects, that if video is re-exported, the audio on secondary tracks go out of sync.

Not always, but with specific sections. So for instance I have music as track two (main sound track to edit to) and then add the sound from the clips. The the first section of each clip is fine, but if I edit a clip into more shorter clips (editing any unwanted bits), that the next clip is slightly out of sync and the one after that slightly more out of sync and so on. At the start of a new different clip and the sound is back in sync. It is only clips that have been edited down to a concise group that seem to suffer.

I have now tried this on four different videos, all with the same result. Even trying to realign the clips doesn't help and in fact while playing the video within MEP everything is in sync. It is only on exporting the problem occurs. These are files with no variable frame rates and worked fine in all previous versions of MEP from 2018 onwards.

OK.

I know what's wrong but not how to correct it.

The clip that gets edited moves and closes the video and audio portions of the clip as it should do but on export the audio portion keeps to its unedited length. I have no idea what is causing this or how to correct it short of completely re-editing.

@CubeAce Delete all the HDPs and HOs?

Hi Alwyn.

Thanks for the suggestion. What happened then was audio is still out of sync on export but showing it is in sync in the same places and playing in the correct places within MEP but I've lost my mix levels pans etc. and now I have additional 'Ghost audio' from parts of the clips I had removed (using the 'cut' and not the 'delete' command) when initially shortening clips.

My work around has been to mute the offending audio tracks after exporting them as wav files and then re-editing them on a new track to fit in and remix. That has worked but is a faff to do.

I feel it has made a bit of a mockery of storing projects for future use and come back to at a later date unless I have done something wrong in making the project in the first place that I'm not aware of.

I suppose I could download the 2018 version again and try somehow to get all versions of MEP on my system but not sure if I can do that as they were upgrades and not bought as new versions. I don't think I can have enough licences to do that.

I know other programs I have will upload old projects and that if I save them in a new version that they are no longer backward compatible. I get warnings to that effect and I accept that as I don't really want lots of different program versions on my hard drives anyway. Also I know some old effects will no longer work and need replacing with newer versions. That is all OK and reasonable. I expect an amount of work has to be done but losing timing on basic track layouts is a new one on me.

Still, it's a problem I won't have that often as I seldom go back to redo stuff. It may also make me go back and delete all old projects and save disk space and just accept if I want to resurrect an old project just to start from scratch with a new one.
