I’ve been struggling the same playback/render issue but finally solved just now!
My case:
- UE5 EA2
- RTX 3080 / 96GB RAM
- Five Media Players playing mp4 videos (later switched to image sequences)
- MRQ render necessary
My problems:
- Either video (mp4) playback speed was about 100 times faster on rendering, or
- playback (image sequence source) completely stopped on rendering
What I tried (solution found on this thread):
- RHI to Default, DX11, DX12, Vulcun, none worked
- ProRes plugin enabled and/or video transcoded to prores: none worked
Final solution to my case:
- Increased two Cache Size in Project settings > Plugins > IMG media from default 1.0 GB to 20GB both!
Found this hint from here:
Media Texture video playback too fast in sequencer render output - #13 by S-Dot
Now finally MRQ renders media playback (image sequence source) correctly. Yeah!
