Do you mean my system specs? 1080p FFV1.mkv plays back with just a little stuttering on a core i5 3570k in VLC, but FFV1.mov just doesn't display video at all, I only get audio on any PC I've tried and the VLC cone appears in the video display window.

Anyhow it seems that the issue I'm having may have nothing to do with resolution. It seems that the issue is with the codec id? This error pops upin ffmpeg with ffv1.mov "[mov @ 0324ac40] Using MS style video codec tag, the file may be unplayable!" . 

The codec id, as displayed by mediainfo for ffv1.mov is 'FFV1', the codec id for ffv1.mkv is "V_MS/VFW/FOURCC / FFV1"

Here's two ffmpeg logs, one for ffv1.mov, one for ffv1.mkv.
