Encapsulated HDV in MOV using Clipwrap

beigemmp 8 Oct 2009 05:46
Are MOV made with clipwrap for mac acceptable? It's basically taking my original HDV clips and wrapping in a MOV file without transcoding. I uploaded a file and it worked. Only down side is the video thumbnail doesn't look very good. Like a low quality render. I haven't submitted to curators, it was more a test to see if it would work.

But because it's only a wrapper, the HDV virtually remains untouched so the file stays small.

Thanks!

And while we're on the subject - if you don't mind me, beigemmp, adding to the question list - has anyone had any other problems with wrapping HDV with ClipWrap? I'm on a PowerBook G4 with Final Cut Express, and wrapped HDV files in FCE don't show any video, just a grey screen with audio.

But to try to give you an answer, beigemmp, my guess is that .mov wrapped HDV isn't going to work. While that would take care of P5's request that the file format be .mov, the codec the video is in will still be .mpeg-2, when they request it be PhotoJPEG or MotionJPEG-B.

.Mov files, if I understand correctly doesn't determine the codec of the video, it is only a sort of wrapper - a bunch of metadata - that tells Macs and software how to handle the video. It's one reason why .mov files are supposed to be more versatile, but at the same time more unclear and complicated. So, wrapping your video as a .mov file is only one step. The other is transcoding your video to one of the two JPEG codecs.

For everyone's reference, here's the link to P5's video specs:

Which is fine I've upload according to their requests. I want to know if anybody else has tried successfully using clipwrap and if there are any issues or problems. I've searched the board with no mention of it. I can only assume if it were being used, it might be working successfully.

I didnt use Clipwrap for submitting, only to make some win-captured HDV files ready for FCP, but I know it works.
The problem of using only CW is not the quality of the footage (which is original as there is no generation loss). Its the fact that you cant trim or otherwise edit the clips (esp. drop the audio in most cases) before the output. Basically, its just a conversion tool.
Apple HDV (i.e. mpeg2.mov) does only work with FCP 5 or later, not with other mac- or win-based editing suites.
AFAIK, the only current option to transcode an Apple HDV clip to another format (like mjpeg or Prores) for win or mac, if FCP is not installed on your system, is a 70 USD tool from convergent media***. There is no free or puchaseable plugin for Quicktime.

(*** correction: "Divergent Media" makes Clipwrap and I think "Calibrated Software" makes the PC tool for Apple HDV.

Cheers (from the I-Cafe),

Ah, that makes sense. Thanks stefgo and truss for clarifying.
