I'm experiencing issues with some clips I've downloaded from Beeple's Vimeo page (
https://vimeo.com/channels/beeple). Playback is not smooth with some of the clips, sometimes it will freeze for a second then come back. I've been using the HD 1080p MP4 versions, not the MOV versions. Looping is not always seamless either, sometimes there's a visible pause when it loops back to the beginning of the clip. Is there something I can do to remedy this? Is anyone else experiencing this?

Cache set to 300 MB (recommended)
1024 MB of video RAM on my NVIDIA GeForce GT 650M
GPU-accelerated video decoding enabled
What is the CPU usage doing when this happens?
Perhaps you could try disabling GPU-accelerated video decoding and see if there is any change? (and restart MixEmergency after you've enabled/disabled this setting)
I will track the CPU usage, try playing videos from the SSD, and disable GPU acceleration, and get back to you with the results.
Thank you Nick.
Any chance there's an issue with the file itself?
CPU usage was steady, between 65-75%, no spikes.
Forgot to mention above that I have 16GB of RAM and my processor is 2.6 GHz Intel Core i7
There may be something else going on with my system, I used ME 3.0.2 with Scratch Live 2.5 yesterday and noticed that even other videos were freezing for a second or two during playback (no scratching or video effects applied).
Will test with GPU-accelerating on and off, and play from the SSD and HDD, and let you know what happens.
Thanks for the tip spotter, I'll be trying that as well.
Please report your test results, I would be interested in them. I too use Beeple clips regularly and have noticed similar chopping and freezing, and I also have a recent MacBook Pro with SSD.
I've encoded the original MOV files with Handbrake. It seems rather irregular which clips play smoothly and which don't, so my first idea too was that if it is an keyframe issue.
After trying several different combinations of encoding settings and file locations, I found that I had the best results by downloading the original MOV from Beeple's Vimeo, then re-encode with MPEG Streamclip as a HAP video. GPU-accelerating is enabled. File location (SSD vs HDD) didn't make a difference.
Re-encoding the original as an H.264 video was OK, but it is not as reliable as HAP. Sometimes there is still a slight hesitation when the clip loops back to the beginning.
The obvious downside to using HAP is the file size (18 MB H.264 vs 518 MB HAP).
In any case, downloading the original MOV file from Vimeo and re-encoding to something else performs significantly better than downloading the HD MP4 file.
Hope this helps you guys.
Say I want to put the visual on another song by having it in my media bank to be used when playing just audio tracks with a different BPM does it respond to the new BPM or does it use the BPM of the song that beeple encoded it with.
