As with all of these Avid tips, if this looks like gibberish to you, just ignore it and enjoy the other less-technical posts on the blog. I make these notes because a) I couldn’t find an easy answer on Google and b) I want to be able to find the answer again myself.

I had a sequence with mixed SD 23.976 clips and HD 23.976 1080p clips in a 1080p/23.98 project. Foolishly, I thought I could batch capture straight from the sequence. Instead, I got this error:
Error on clip 0J0011.new.18: This clip cannot be batch captured because you are in a 1080p/23.976 project and this is not a 1080p/23.976 clip.

Error on clip [clip name]: This clip cannot be batch captured because you are in a 1080p/23.976 project and this is not a 1080p/23.976 clip.

This happened even when I decomposed the sequence, creating new clips at DNxHD 175. But the Format on those clips remained SD 23.976, even when I tried modifying the sequence to 1080p before decomposing, as suggested on forums. (That gave its own message: Your sequence is already in the project format you selected.)

The solution, loosely based on this Creative Cow thread, was to export an Avid Log Exchange (ALE) of a bin with all of the SD 23.976 formatted clips. Dragging this into a new bin in the same 1080p project created new clips that finally read HD 1080p/23.976 under the Format heading. Then I captured these clips and relinked them on the sequence.
