Steps to reproduce: 1. Put any file in Content/Movies 2. Create a Media Source Asset 3. Link the Sample video on it 4. Create a Media player 5. Play the sample video by double clicking on the media source inside the media player Cheers, maxzerr Edit: Same thing happens in 4.13.1 as well. 4.12 plays it perfectly! ---

What file format is the video you are putting into the movies folder. UE can be picky with the files ---

This was recently fixed in Dev-Sequencer (CL# 3168760). As a temporary workaround, do not use videos with dimensions that are not multiple of 16 (i.e. 360 in your video is not a multiple of 16). ---

Hello there, I have a similar problem too as I’m trying to upload .mp4 file but it can’t find the pathway to the file. Initially it worked with my 4.27 and I could upload the video and posted on plane and everything went well until I forced deleted the video to change to different video and then the nightmare started. As I don’t use C++ for my project, please advise what should I do. My project is created by using 4.27 assets so I can’t go to a version below which is the media source still working. I tried to uninstall and reinstall 4.27 and still doesn’t work.
