Recording broke into segments MXF packets

Need help - recorded for 1 hour straight with my XF300 and when i downloaded files off my card i had 10 MXF packets making up that hour - why the segmentation? shouldn't i have just 1 packet? each packet was exactly 5:13 in length... thanks in advance - steve

I work in Avid MediaComposer 5.5 and there is no problem with this segmentation. The media can be segmented, but a clip in timeline is not. I link all clips from the card with AMA (AvidMediaAccess), it's very simple (one click), then I can consolidate media to another hard disk or transcode into a different media codec. There is no problem with the segmentation.

I always copy the entire structure of the card when backing cards.

Re: Recording broke into segments MXF packets

The filesystem being recorded to the CF card has file size limits, hence why it splits into 10 files. If the camera used a proprietary file system, it would possibly defeat file size limits at the cost that the CF card will not work on a standard PC or any other device. This is not ideal so most of the manufacturers stuck to the universally accepted FAT file system, which has a 4GB file limit.
