I’m attempting to use the VSE for editing a short animation I’ve been working on, and it seems to have great difficulty keeping up to realtime playback. This is especially becoming a problem now that I’m adding audio, as the playback seems to be even slower with accompanying audio tracks.
A little info on my setup:
-Phenom X4 2.5Ghz
-Nvidia GT240 1GB RAM
-8GB main memory
-Ubuntu 10.10 64bit
-Nvidia proprietary driver (v260.19.06)
-Blender 2.49b 64bit
I’m using image strips from PNG files, at 720p (1280x720)
So what’s the problem here? My setup isn’t screaming, but it should certainly be sufficient for some simple video editing! It seems like blender is just being incredibly inefficient. I have noticed that during playback on the VSE, blender is completely maxing out one of my cores; perhaps it’s bypassing hardware acceleration and doing everything in software for the video display? I can’t comment on that really since I don’t know anything about Blender’s internals, but it seems to be the case.
It would be really great to do the editing work in Blender, but this isn’t usable. Can anyone share what their experiences have been? Perhaps it’s better on Windows? Any tricks to speed this up? Am I missing something? Is it any better in 2.5? Any thoughts/suggestions appreciated. It’s looking like I need to use another NLE; kdenlive perhaps?
And yes, I should move on to 2.5, but I didn’t want to migrate my project to alpha/beta software in the thick of things:-\
