VSE not playing in realtime (not caching)? I have some exr sequences in the VSE, but they won't playback at 25fps.
Some parts play fine (random), but then it feels like it is caching again at 6fps or something. No matter how often the loop is running it always gets these hickups.

The 'cache memory limit' is set to 16000, but that doesn't help.
Is there a way to see if/how much of the cache memory is used, or is there anything else I can do about it?

thx
While you're playing your sequence, you should see a little fps counter in one corner of the preview. If it's red and below your frame rate you set beforehand, than your computer can't handle the preview rendering in real time. This can be related to memory, but (at least from my experience) it more likely depend on your CPU.

What you can do to improve the playback, is setting up proxy files. They're typically smaller so playback is easier.
