Makes for bad video, sports videos are unwatchable. 2) Any movement, even a wave or lifting an arm, while in front of a recording consumer level HD camcorder, results in screen ghosts and artifacts being left on the video track, following the movement. 1) Blurry, fuzzy, out of focus areas closely around people in videos taken by consumer level HD camcorders. Consumer level HD camcorders have 4 problems. Maybe you need Updates or Lion for proper graphic drivers.A. atMonitor reports disk read i/o between 1.3-1.8 MB/s during playback of these 2 clips. Blackmagic Speed Test read results for these drives: Boot SSD 180 MB/s, Internal storage SSD 259 MB/s. No monitor, external 1920x1080, and triplehead2go at various resolutions all exhibit the same problem. Composition size matched to display resolution, to ensure no output scaling. No scaling for either clip, no scaling for either layer. Composition contains 2 layers, 1 column, and only these 2 clips. It should be noted that one of these clips is a stock Resolume footage shop clip (RebelOverlay-DigitalWarfare_digi_1.mov) DXV 800圆00 30fps. However, this is not accompanied by a drop in FPS. I have random periods of 'stuttering' of all (2) clips synchronously. hardware controlled.Ĭgion wrote:I am having similar issues with playback smoothness.

Any thoughts?įresh install of Mac OS X 10.6.8 with only Arena 4.0.1 demo, MPEG Streamclip, and atMonitor installed.īoot Drive: OWC Mercury Extreme Pro SSD (3G) I am having similar issues with playback smoothness. I hope that sheds some light on the situation. We recommend using SSD drives with DXV encoded footage for the best results. Either the problem is the CPU is overloaded because a non-optimized codec is used, or the read speed of the hard disk is not fast enough to read all the data.

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.
