Why do you need to read out the binary data?

I do not, but if I don't then the conversion will need to happen every time
the movie is loaded.

Yes, in that case I would do the conversion in system memory and save
out the compressed form to a cached folder/file. This will speed
subsequent loads. Storing lots of uncompressed frames in memory will
eventually exhaust video memory and result in texture thrashing
between system memory and video memory as you run through the video
frames.
