Try placing a matte down on video one and moving everthing up.
I have read other posts with things not rendering right sometimes with spaces or gaps.
Others might know of the reason but I forget.
Give it a try and see if it helps.
Why is this always such a problem with Adobe Premiere?
Not sure it is. Mine always come out right.
The choice of player is often a factor. QuickTime or Windows Media Player aren't the best. Try something like VLC or KM Player.
Thanks guys. The problem with players is that clients usually don't have options like VLC or KM and it's frustrating when some videos play perfectly well and others slip out of sync, even if it may not be Premiere's fault alone.
That is the realty of the situation.
Just like a cinematographer, who works so hard making the image look just the way he wants, has no guarantee that the end viewer will have a properly calibrated display and see the film the way it was intended to be seen.
All you can do is your job correctly, and offer suggestions to those whose systems don't work right. Which in this case means using a decent media player.
