7D Conversion to ProRes Loses .THM File
I have successfully converted my Canon 7D H.264 clips to ProRes422LT with Compressor, Streamclip, and FC Log and Transfer. All proving to be perfectly acceptable paths, with one exception. None of them carry over the accompanying .THM EDIF files.
I utilize the information in these files via Canon’s ImageBrowser (Mac).
So, question: Is this just a reality I have to face if transferring to ProRes, that I will lose connection to that EDIF info, or am I missing something here and those .THM files should be transferring over as well?
BTW, I realize I could always go back to the original H.264 files where the .THM lives if I need, but without complicating this thread question, suffice it to say enough things change in my process that makes this idea difficult.

Carry over how? WHen you convert the footage, the H.264 file, it becomes a new QT file…ProRes or whatever you designate it. The THM files aren’t brought over too…they don’t go into the CAPTURE SCRATCH drive. I don’t know what you mean by this. The QUICKTIMES are converted…not the secondary files.

As you know, 7D media clips are accompanied by a .thm file with EDIT information from the camera (ISO, fStop, Shutter speed) valuable information that I can see when viewing the original clip in ImageBrowser.
However, and as you know, Log & Transfer ingests clips,converts them to a single QT file and ignores this companion .thm file.
My question/post was to verify if I was understanding this correctly and accept the fact that proceeding with this traditional FC conversion routine with 7D clips, that I would also have to accept losing the .thm file EDIT data (unless, of course I reference the info from the original clips via ImageBrowser).
Was hoping I was missing a FC import setting that would somehow “pick up” that companion file and merge the EDIT info into the single QT file.

FCP does reference that file. That’s how it gets timecode onto the clip…the TIME OF DAY data from that file. It just doesn’t bring over the other information…it ignores it. FCP ignores a LOT of metadata…and from a format that it has worked with for a long time too, P2. There is much metadata it doesn’t deem Necessary.
But, I don’t think as an editor you need to know what lens and F-stop were used on each shot. Certainly that’s nothing I’d need. But, I know the frustration.

Okay, thank you for taking the time to confirm what appeared to be the obvious to me, but wanted to make sure.
My desire for that info was to have the luxury of working within FC to view, sort, and “play” with various test shots and see those settings while I learned using this camera. But I can do this through ImageBrowser and the original footage.
