We usually export our timelines to MPEG or Windows Media, so I don’t think this sort of freeze during an export to tape has happened a lot in the past. The exports to .mpg or .wmv are trouble free. This is a large production environment with multiple users. The Promax computer is less than a year old. We use a Convergent SD-Connect (sold by Promax as a Pro Media Converter) with a generic OHCI card to get the footage into and out of the box.
The 1.6 TB video raid drive is fairly unfragmented, with 86% free space.
Regarding the project settings in the “frozen” project, it was a DV-NTSC 48K Standard project, 720X480, 29.97 fps, D1/DV 0.9, 48Khz, millions of colors, non drop, etc.
The General settings were all default, with all the Capture options checked.
The Video Rendering settings were all default, with Optimize Stills checked.
The Default Sequence settings were 3 Tracks, Stereo, all other boxes on 0.
