    Pardon me I’m a noob to this.
    The video started turning black randomly. Originally I wasn’t having this issue, but as time passed over the past few days it started up. First it was when I was using 1080x720p videos. I went down a res to fix that. Next it was when I had three v002 Movie players in my workflow. When I disabled the third it stopped. Then it happened with two playing. Now I see it happening in a simple composition with one movie player. The composition in the viewer and video feed recorded in the Syphon Server both have the issue.

    I have closed every application and allocated the most memory I can to Quartz Composer via renice, restarted and opened only Quartz, etc. It still happens… Any help would be very appreciated.

    Datamosh is slow. If you blame the movie playback, see if you can play back movies without any effects at full framerate. Check your codec and bitrate.

    To be clear – ensure you can play back all 3 movies with no effects – this will incriminate either your CPU or your Disk.

    If you have super high CPU usage and drops frames, change codec to something thats more efficient to decode like MJPEG or AIC or Pro Res 422

    If you have high disk access and you cant “keep up”, use a lower bandwidth codec like MJPEG, AIC, or h.264.

    Datamosh is very intensive, not necessarily ‘slow’ – just needs to be tuned and treated with care. Its not GPU accelerated 🙂
