Howdy from ClipWrap

[Colin Mcfadden]

Do the files play properly in QuickTime player? What if you do a transcode to a format like Apple Intermediate?

[Fabio Bressan]

They do play in QT Player, but not very well, and they start getting juddery and frreezing after a while.
I could transcode of course, but the reason I’m evaluating Clip Wrap is because I’d like to rewrap (not transcode) MTS files into MOV so that I can grade my Premiere edits later in DaVinci Resolve.
I have this codec installed, may this be the problem? https://eww.pass.panasonic.co.jp/pro-av/support/dload/avccam_impt/dl_e.htm

I’m on Mac OSX 10.6.8

Thanks

Hmm, it sounds like you may just be CPU bound. Playing 1080p50 h264 without hardware acceleration on an older machine (I assume, since you’re on 10.6) may just be more than the machine can handle. I’d like you to try a transcode just to rule out codec incompatibility.

You can contact us directly at support@divergentmedia.com if you want to dig in further – it’s a bit easier to handle a thread like this via a ticket.

I can handle 1080p 50p MTS, MP4, MOV clips with effects applied with no problem, in realtime. I switched back to MTS clips for the moment, I’ll contact you through support if I’ll try again in the future.

Thanks

Thanks for this post Colin! We are also shooting AVCHD (along with two other secondary formats) and evaluating ClipWrap.

Question regarding the terminal tweak you recommend. What actually does this do to the media and/or wrapped clip? “iMovieHD” I don’t get it. Is it merely faking out Premiere Pro? If it makes Premiere think it’s an iMovieHD file, are there any long-term ramifications, like if we end up switching to another editing ecosystem, etc?

[Colin Mcfadden]

This is an old thread – none of that stuff is relevant nowadays, as we’ve got a special dropdown in the app now to select the optimization.

[Cg Coffyn]

We just purchased ClipWrap and saw the drop down. How will optimizing for Premiere Pro affect the use of the ClipWrap footage in other non-linear editors? What does the optimization actually do, the same as the terminal tweak?

It’s good to post this here I believe, as others will come across it and the info will be helpful. Maybe you had a link too addressing this on your site.

Thanks!

There are two ways to store h264 I frame offsets in a QuickTime file. Premiere and iMovie like it one way, FCPX another. The files work either way, but you won’t get as fast performance if you mix incorrectly.

Thanks Colin, this is helpful as we are trying, as much as one can, to look forward to future workflows. We have decided to keep the original AVCHD structure in addition to the ClipWrap movs. Seems the wisest, all things considered at this juncture.

In our brief tests this new optimized tweak in ClipWrap seems to play as well on the Premiere Pro timeline as the original mts. Looks like the ClipWrap folders are a tiny bit smaller than their mts counterparts. We’re guessing that the crazy AVCHD structure adds a bit.

Thanks again for the speedy reply! Keep up the good work at divergent media. We greatly appreciate it on this end.
