Removing Aperture info from FCP7 QT files
-
QT Pro doesn’t expose the atoms so they can’t be edited there.
Tell me more about FFmpeg. It can edit a QT file?

QT pro does let you switch the aperture…
Would be the easiest way.
(check the properties, last tab i believe)FFmpeg can handle QT just fine (but not QT ref containing multiple clips)
Experiment with ffmpeg -i input -vcodec copy -acodec copy -aspect 16:9 output.mov
But you’ll loose TC info. (Not sure if that’s important to you…)

No, QT only lets you change the presentation setting (Classic, Production, Clean, etc) not the actual aperture value.
TC is very important, so I guess I’ll have to skip FFmpeg.
Thanks!

That sucks….
I would think that if you set the params in QT, you ‘should’ end up with a clean QT….However, i am able to use FFmpeg AND add the TC to the fresh file.
And i’m probably able to create you some custom code to get from A to B.Contact me direct if you like, we probably can work something out.

Thanks, but we may have written something to strip out this data.

I’m familiar with this problem. And it is the mere existence of the ‘clap’ atom that causes the problem.
I’ve been using Compress 3.5.2 to fix the issue, let me know if you’ve succeed in writing something for stripping that atom.

I was recently having a similar issue, but we seem to have found a solution. JES Extensifier https://www.apple.com/downloads/macosx/video/jesextensifier.html will edit the individual atoms, and it batches. I personally have not used it yet, but it has already been implemented into our workflow, so I imagine it has been approved. Let me know how that works for you. 🙂
