DUMPMOVIE or anything to record Matinee with Media Player?

Hello guys,

for a whole month I have been working on a project, and I cannot seem to export it in any way. Dumpmovie doesn’t work, because it lags and leaves out frames. Record movie in Matinee doesn’t work because it doesn’t sync up with my video textures, which are super important in this project. I have tried making console commands, bat files, custom matinee tracks, panner textures, but nothing works.

Please, could you help me with this?
