Trim original footage to a new, shorter file

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

It doesn’t work on any interframe codecs (which are increasingly common on the production side).

If storage/archival on the back end is an issue…

then it makes a case for transcoding on the front end.

the ideal would be to be able to edit native and have a transcode option as part of the “Project Manage”

I would build a preset in Media Encoder that matches my footage and transfer/transcode all the selects that way. I did this just last night with a bunch of GoPro footage and timecode matches and image quality seems identical. Plus I got to rename the clips to match the project. Three days worth of 5 minute camera rolls on average. Biggest clip I marked was probably :30.

Paul…

is this starting in Prelude?

what’s you exact workflow….

and how do you handle cameras with lot of channels of audio?

thanks!

It’s all in Prelude. The stuff last night was just .mov and the audio didn’t matter. Mike doesn’t mention the audio set up on his stuff so I can’t say what he would do with that. So, you might have to go to MXF OP1a/XAVC Intra 4k to get access to more than two channels of audio, but even then PPro loves that stuff and given that he’s only looking to use 10-15 seconds off of each shot Media Encoder would whip through that. And the originals would remain untouched of course.

My workflow was simple: Opened Day 1 folder on the drive the DP gave me, marked the parts of the clips I wanted, selected Transfer, picked a location and created a subfolder called Day 1, selected Transcode and selected QT/DNxHD, selected Rename and called them Day1 with auto increment.

Rinse and repeat for Day 2 and Day 3.

Normally I’d mark subclips so I’d always have access to the whole clip, but these shots were pretty obvious as to what was going to be needed.

ahhhhhh….

so that answers a big question for me. Cool….

The other methods mentioned would be more efficient for lots of files, but I just wanted to point out that there is a more direct way in QuickTime than copying and pasting to a new player. Once you’ve got your in- and out-points marked, go to Edit->Trim to Selection. Then File->Save As to your new file, making sure “Save as self contained movie” (as opposed to “save as reference”) is selected.
