Hello guys!
I was setting a sequence I made in Blender, for my timer widget. I restarted UE for an Electra plugin, and then it all went down. (media source, media texture)
I have tried to reimport my animation sequence several times, but I keep getting these errors and have no idea how to fix them. 
(I also tried to add the directory that hosts the mp4 in the project settings too)
It doesn’t work anyway.
Suggestions?
Thank y’all!
For anyone who might have the same problem in the future, here’s how I solved it:
For the file path excluded from the packaging, go to your ue project directory, and in the content folder create the “Movies” folder, physically move your videos there, restart ue and re-import the video/videos into the content drawer in the exact same Project/Content/Movies folder..
For the Electra plugin error that prevents the video from playing, make sure that the format/encoder you used for your video is compatible, if not change it. In my case the problem was the encoder, I solved it with “H.264”.
