Because I am building slide shows - I use 30fps Timecode. I usually export at 10fps without any issues. This evening's exports were at 10fps (like I had always done).
I just exported at 30fps: no unwanted transitions.
Why no problems before, but now?
Try a 10 fps export with frame blending turned off for all of the stills.
Thanks. Unfortunately, that didn't work.
What works: Export at 30fps.
What works: Copy entire Timeline and paste it into 10fps Timeline and Export at 10fps.
Something is definitely not working correctly. Don't know if it is here or with the updates to Premiere Pro and Media Encoder I recently installed. Just tried a 10 still 30fps Timeline exported at 10fps and each still was overlayed with the adjacent still. Export at 30fps and no problems.
Deleting all you render files (menu option) and then re render the workarea bar.
