The latest version of Premiere (12.1.0 (Build 186) seems to be extremely buggy.
Currently I have a file with 3 Sequences built into it.
Each sequence contains the exact same set of clips, except some clips are shorter or longer.
When the mixed sequences were played in Premiere, the playback was perfect.
But the first problem occured when exporting the mp4's.
1st a png which was set to scroll, stopped scrolling completely when played back as an mp4
2nd A translucent Png which is inserted as an end card, turn from a bright white with a logo to a bright magenta upon export
3rd After a series of quits and relaunches of the program, the end card png would occasionally the translucent portion of the png would turn magenta while simply reviewing the playback within the app.
Does Premiere no longer accept png's?
What's going on?
I have never had these issues with any of the past versions of this app.
A new update became available today.
Updated and problem has been resolved
Please update to the latest version - 12.1.1 which was released earlier this week. It has a fix for a couple different PNG issues.
