[PD] tips for loading a long video with GEM

[enrike]

hi all

We tried to open a whole movie with GEM but PD really struggled. The 
frame maximum rate we achieved was very unstable and around 1 / 0.5 fps. 
The file was an mp4 with H264 compression and it was around 1.1G if I 
remember well.

I kind of remember that compression settings (intraframe) might help as 
some of the problems might have to do with compression being too high 
any tips?

thanks
