Dear Epic Development Team and Community,
We have encountered a frame-skipping issue when rendering Media Plate Actors using image sequences in Unreal Engine 5.5.3.
This issue has been verified and reproduced consistently by multiple users.
Issue Overview
- 24fps → All frames render correctly
- 30fps → Unless the Temporal Anti-Aliasing Sample Count is set to 1 or below, only every 2 frames are rendered
- 60fps → Only every 3 frames are rendered
- In Sequencer playback, the media appears smooth with no frame skipping
- The original footage, image media source, Sequencer, and Movie Render Queue are all using the same framerate (fps)
- The PC used is sufficiently powerful (i7-11700 / RTX 3060 Ti / 64GB RAM)
What we tested
- Source footage shot at 60fps, converted in After Effects to 24fps / 30fps / 60fps image sequences and tested individually
Theory
It seems the Media Plate Actor (or image-sequence-based Media Source) may be internally optimized or limited to 24fps playback.
This could be a bug or a design limitation affecting how Media Textures are rendered at higher frame rates.
Request for Help / Advice
- Is this a known bug or intended behavior?
- Are there any settings or workarounds that allow Media Plates to render every frame at 30fps or 60fps?
- If this is a design limitation, we’d greatly appreciate it if it could be considered for improvement in a future release.
Thank you for your time, and we’d be grateful for any insights you can offer — even small ones.
Looking forward to hearing from you.
Test Environment:
Unreal Engine: 5.5.3
OS: Windows 11
CPU: Intel Core i7-11700
GPU: RTX 3060 Ti
Memory: 64GB
