Hello, I've seen many people have this problem, but I've tried some solutions I found in forums but none work.
I am using two clips I saved in Premiere using the folowing setting: H.264 i HD 1080p 29.97 and H.264 i HD 1080p 25 ( I just found I saved them using a different frame rate)
1) .MP4 1920x1080 25 frames, 30 minutes. Time stretch: 3 minutes
2) .MP4 1920x1080 29,97 frames, 25 minutes. Time stretch: 15 seconds and a mask,
I've tried using a different clip instead of clip 1, so both clips have 29.97 frames per second.
I am changing the position of the second clip, and when I get close to the end of it, around 14 seconds, I get the message
I've tried conforming to the same frame per second.
I've tried importing the project to a new project.
Don't use H.264. Simply use image sequences. These are usually MPEG decode errors - for whatever sickening reason.
