I'm new to Avid ediitng and recently upgraded to Media Composer 7.0.3 on my MacBookPro (OSXMaverick 10.9.1).
I imported a 5.17GB .mov HD video file at 1080p/29.97 with raster dimensions of 1920x1080. This does not play smoothly in the Avid. I have attempted to output, left it running all night, and finally aborted. The partial file was over 80 GB.
Output settings were 16:9 (1920x1080) Fast export Quick Time NTSC. I'm stumpted about why this is such a big file when the original was so much smaller - and of course, embarrassed as I'm sure it's something simple and obvious.
Can anyone help?
