Hi,

At a conference a few months ago, I shot a ton of stuff over 4 days. A few (very few) of those clips were timelapse files. The edit is finished and they didn't include the timelapse. I inquired as to why and no one had seen it. On further investigation, the files didn't make it on to the edit system. I loaded the raw cards and the timelapse files aren't on there either. I recall the date and time I shot them, and surrounding that, I can see clip 128, 129, 130... then we skip 131 (the timelapse), and at 132 we have the shots I took after the lapse. Looked both in the file structure and via Catalyst Browse. Even searched files for anything that had "131" in it. Nothing.

What happened to these files?

I record simultaneously on both slots - A and B. 64GB in A and 256GB in B. We edit off the 64GB card and the 256GB card stays in the camera as a backup. By some miracle the 256 card from March had not been re-formatted or re-used yet, and the timelapse shots were there right in order on the B card.

Why they are not recorded on the A card I have no idea. Luckily we still had the B card.
