Trim original footage to a new, shorter file
Hello
I have a bunch of Apple ProRes 422 HQ 3840×2160 footage. In a lot of cases, the camera was rolling for several minutes, but I really only need a 10-15 second part of the clip. I would like to cull this section into a new movie, but retain the original codec and size, as well as keep the original time code.
I thought maybe ingesting with Prelude would be the answer, because you can mark an in and out on a clip before ingesting. However, I find that it only works if I am transcoding to a new codec. If I mark and in and out, but keep “Transcode” unchecked, it actually just duplicates the entire original, ignoring my in and out marks.
Any advice on a way to cull my footage? Maybe there’s another method or software I should be using. I do have a workaround, which is to open the video in Quicktime 7, mark an in and out, copy, then go File >> New Player, and paste, then save. This seems to work, but also feels like a clunky way to go about this, especially since QT7 is so old.
Thanks much –
Mike

I totally understand wanting to pick selects out of long camera rolls. Is there a space requirement/restriction that you’re working with that you wouldn’t want to copy the whole clip?

Hi…
1) Can you transcode to the same codec/settings? This shouldn’t recompress.
2) a) if it’s quicktime (true)
b) if it’s marked (true)you could essentially drop it all into a sequence…
then Project Manage it and that would allow the creating of a trimmed set as well…

Yes, pretty much a space issue. First time the crew has shot 4K footage. They way overshot, particularly on the first day when they weren’t really thinking about how large the resulting files would be. The other solution, of course, is to just buy more storage, but I was hoping to keep the clips to a more manageable size.
I found that my Quicktime 7 method also works in MPEG Streamclip, though with Streamclip it doesn’t show me source time code when looking at the footage. The original time code does carry over to the new clip, so that’s a plus.
It seems like Prelude is almost there for this task – I don’t understand why it ignores your in and outs if you are transferring clips to a new destination but not transcoding. Maybe a feature request is in order.

Yeah, I hear ya. But it’s kinda looking out for your best interests there too. You ingest all the clips you want, mark subclips of the parts you want (including multiple and overlapping parts of any single clip) and just stop there. Then when you import any of those clips into PPro you get the whole clip AND the subclips. I think they did that for those “I think there’s another shot on this clip I might want” moments. Or you could open original Prelude session, select the the subclips and just send them to PPro.

Thanks for the advice. I’ll give it a try…

As to “Project Manage it and that would allow the creating of a trimmed set”, I’ve tried it.
It doesn’t trim the footage. -
it doesn’t support a lot of formats….
it should work with quicktime.

Just tried it, it worked for me. Thanks for the advice.

Well, I guess one of the “lot of formats” is AVCHD/mts.

yep.
