    Hi !
    I want to build a AV sequencer that can play about 50 video files at once (using alphablend). The movies are short animations that appear mapped on the screen and form a composition. These 50 files belong to 1 set, and I have more sets. I want to be able to change between sets instantly.
    How would I load and play such large amount of video's?
    I was thinking about using the HAP object and video textures.
    Can anyone point me in the right direction? Thanks!

      50 simultaneous clips sounds like a lot. i don't know if hap would help in this case but maybe. my recommendation to try first is to read all the clip frames into memory using either jit.matrixset or jit.movie @engine viddll loadram.
      the clips should all be exported at the dimensions you expect them to be displayed at. i would implement this in javascript for the most ease and flexibility while experimenting.

      Hi Rob. Thanks for your answer! I've no experience with javascript yet. ps: I'm working on a mac. Do I still use the viddll engine then?

      if you're dealing with 50 videos to form a composition, they could probably be super super small? I would load the videos inside jit.movie objects in 50 instances of a [poly~ 50] and then you load your new "set" by loading a new poly~ with the message {patchername blablabla]

      If I use poly~ , can all the files be different? (I have 50 unique movie clips)
