This is caused by the system not being able to keep up with getting all the data. Jittering playback in all clips, where the playhead also struggles (most likely accompanied by a drop in the fps). We are experimenting with different techniques to lock this down, and have made some progress in the update mentioned, but it continues to remain noticeable if you are indeed 'glued to the screen'.Ģ. This causes a tiny perceptual slowdown of the footage. If your clips are 25 fps (or 50, or 60, or 29.97) and the refresh rate is something other than 25 (or 50, or 60, or 29.97 or an exact multiple of that), sometimes the screen has to display a particular frame longer than other frames. This is caused by discrepancies between the clips fps and the refresh rate. Jittering playback in slow moving clips, where the playhead continues to play smoothly (most noticeable on clips with horizontal scrolling content). There are two main problems being lumped together in this thread.ġ.
totally noticeable and totally NOT pro.Īny feedback on how to optimize osx or get rid of the stutters would be awesome! is there something i could do for my system to make this problem go away? this is a fairly top of the line mbp but with the stutters, it's like having your music glitch out in the middle of a set. i've recently reinstalled osx so there's only ableton on there and the res 4 demo. i bought it brand new in march, 2011 with all the highest features added in. unfortunately the material within the footage clips is subtle and slowly evolving with allot of lush detail that helps keep the eyes glued to the screen so when the stuttering happens, it feels really obvious and really bad. they range in time length from 30second to 3minutes.
and i'm only playing one clip at a time, no layering. I've been running the res 4 demo for a few days now and am noticing a few random stutters here and there when i play clips.
