Hi
Downloaded OK. Very nifty video with 32 tracks. Well done! As you can see it all played OK in preview. Currently exporting as a 3840 x 2160 mp4 at 29.97 fps.
33.5% exported so far...........
I'll edit this post when it completes and let you know if it's all there. Currently using VP 8.20.
Hmmmm! Exported video stopped after 18 secs.
I'll try another export....
1280 x 720 mp4 exported correctly. No idea why first one stopped.
