I'm trying to use Kinovea (version 0.8.15) to combine pairs of videos together into a single video. Sometimes they work, but most of the time the two videos in the combined video don't stay in sync (i.e. one plays at a normal-ish speed while the other is much slower)

Things I've tried include:
> Trimming both videos to be the same length within tenths of a second of each other
> Using the "Synchronise Videos on Current Frames" button
> Setting the save format to different formats
> Converting the Original File formats to other ones before combining them.
> Trying different computers

Any ideas?

I have a similar problem with 8.21.

If you set, or reset, the 'working zone' after 'sync' has already been set, the 'Motion, High Speed Camera' speed will change.  Check the speed for each side and correct!

The synchronization mechanics has been rewritten and many issues should be fixed in 0.8.22.
