So after I export my project into mp4, i watch the video and it constantly flickers between what's supposed to be shown and a black screen like a strobe. I exported it as h.264 and match source. It is a very big project (7 mins, 600 MB after export) with a lot of effects, adjustment layers, etc. What i assume is part of the problem (but may have nothing to do with it... idk) is that I have footage that is 59.94, 23.976, 25, and 30 fps all in the same sequence but the sequence settings are set to 23.976 (so it exports as 23.976). I was under the impression that it would work fine to put various fps footage in a sequence and for example, Premiere would just cut out every other frame of a 59.95 fps piece of footage to fit in the sequence. Is this not the case?
I have changed the renderer from OpenCL to Metal to Software only and it still flickers after export every time. Please help!!
EDIT: I have also tried rendering out a small portion of the video (like 20 seconds of it) and it turns out fine, with no flickering. Could the issue maybe be with my computer not being able to handle such a large export?
Hi Jake, were you able to solve this issue? I have the same problem
I think I just set it to Software Only (file>project settings>general>renderer>Mercury playback engine software only) and that did the trick. I also set the bitrate encoding to vbr 2 pass. I don't know if that helped with the flickering though. I think it was just the software only that helped.
I was having this problem when queuing through media encoder with Premiere 2018. I found if I exported it directly from Premiere it wasn't happening. Maybe I need to update Media Encoder, but my Premiere 2018 runs very slowly on my computer so I had to reinstall 2017. If I upgrade media encoder it might not work with 2017. So I guess some experimenting is in my future.
Even though this post is over two years old, I struggled with the same issue today. I believe my problem was using b-roll that had a higher frame rate then my main interview footage. I dropped the Effect "Posterize Time" on my b-roll and that took care of the flashing after exporting the video.
Here's another quick example. I just googled this topic because I was having the same symptom. After trying some of the solutions in this thread without luck, I realized that I had shadow/highlight effect applied twice to each clip. Removed the redundant effect and the flickering went away. I think I've done this more that once (accidentally applied the same effect multiple times). I need to figure out how I continue to do this so easily...
Can also try nesting the footage in a sequence that matches the footage frame rate settings. So main sequence is 25fps or whatever, your b-roll is 59.95, put b-roll in a 59.95fps sequence and nest that sequence into your main 25fps sequence. Should clear out any frame rate related problems.
