use ffmpeg or handbrake to "hardsub" the movie and convert it to MP4 if it isn't already, and then upload it to some file host.
The mp4's video track should be h.264 (8-bit), audio should be AAC (I usually do it at 192k bitrate). VRC does not support subtitle tracks which is why you have to burn it into the video.
I do this for anime and it works quite well.
