Cinema tools - conformed 720p60 down to 30 can it go back?

The subject explains it, I guess!

I had footage at 720p60 and conformed it down to 29.97 for slomo. I need to bring it back to original speed. I can't conform it in Cinema tools to 59.94. Is the process just to speed it up 200% in FCP?

Yup, gotta speed it up in FCP 200%. The conform is destructive...can't go back.

Or just import the clip from the original source...

It's been my experience that the conform
is not destructive. You might want to Duplicate the media, though. That way you can have a 60p and 30p copy.

It is destructive Jeremy. The file is actually being changed. Unlike in FCP where if you do a speed change, the main file is left alone, while the speed effect is part of the project file, or when rendered, a separate render file. Destructive means that you are changing the file...and that's what happens.

Yes, it would be better to duplicate the file before you Conform, because the process is destructive. If you want to have both a normal speed and slow motion version of the clip.

[Shane Ross] "It is destructive Jeremy. The file is actually being changed"

Not really, all that's happening is that the part that tells Quicktime or whatever device to play it back @ 59.94 fps tells it to ply back @ 29.97, this doubling the playback time. You can easily just conform back to 59.94 as if nothing has changed, that's why it's so fast to conform in CT. I see what you're saying but it's not totally destructive as you can easily get it back by another trip to CT. There's no transcoding or losing of any frames or making up of new frames. It's all the same frames played back at different speeds.

I've never been able to conform back.

I'm an idiot. CT doesn't go back to 59.94, I forgot.

At this rate, you would have to use Compressor, or recapture/relog and transfer your original clips.

Sorry for the confusion.

I'm laughing at this discussion because it just confirmed what I thought. You can only reduce the frame rate...thanks for your guys help. I'm using gopro footage, so it's transcoded from h264. I'll just create one 29.97...then just speed up the clip I want at full speed.

[Jason Brown] "You can only reduce the frame rate...thanks for your guys help. "

Really sorry for the bad info. If Cinema Tools had a 59.94 option, you could do it. I used to go back and forth between to 23.98 and 29.97 all the time.

[Jason Brown] "I'm using gopro footage, so it's transcoded from h264."

I would simply keep the stuff you have now and make a new version from the h264s @ 60p.

That's the plan Jeremy.

Thanks so much for all your help...you and Shane are an amazing resource for all of us.

BTW, what would it require to get a log and transfer option for GoPro footage? I use quite a bit of it, I've created droplets in Compressor....but I'd like to not have to archive the ProRes transcodes.

Is that something the software manufacturer has to create as a plug-in for FCP? Or can anyone develop something for that? I'd pay for it if just anyone could create the plug-in.

That's up to the manufacturer (like the Canon Plugin was), or up to Apple. I wouldn't count on it. They aren't as popular as the canon cameras are.

It's possible, someone can write a log and transfer plugin, you'd just have to find the right person.

Haven't tried, but this application from Bouke Vahl should make the trick:

Nice one, Raf! That does look like it will work.
