HDV / Intermediate codec / Workflow
I’m doing a multi-screen project for an exhibition installation. Three simultaneous streams video, eventually played back from either synced DVD players or hard drives (SD MPEG-2).
Three screens of PAL-res video butted together in my composition (with a bit of overscan overlap) work out at about 2000 pixels across and 576 high.
I’ve shot in HDV. Currently test-editing in native HDV. About three streams of HDV running simultaneously, sometimes four. All looks great. But when I add my blends, masks, titles, blah and blah, my dual 1.8 G5 with 4Gb RAM wants to take 19 hours to render a minute of video at this size.
So I reason my CPU can’t handle decompressing all those streams plus doing the blends etc. My understanding is I would be better off converting my footage to either DVCProHD or Apple Intermediate Codec, or something else…
Before I recapture from tape – any advice on what codec will look better? Any advice on whether I could just do a Batch Export from my already captured files to either codec, rather than recapturing?
Thanks in advance –

No need to recapture. Your best bet is to convert the native files to DVCPro 100 HD. Its a good looking codec, universally considered to be better than Apple Intermediate, and it takes up way less hard drive space than the compressed HD codecs.

DVCPRO100 (HD) is a compressed HD format. no?

They are all compressed actually, but 8bit and 10 bit are referred to as uncompressed. DVCPro 1000 while farily highly compressed vs. the so-called uncompressed codecs, is considered to be one the best intermediate codec available, with minimal artifacts, excellent resolution, definition, and color.

thanks for the replies –
…ummm, DVCProHD and DVCPro100HD are the same thing, right?
If not, where do I get the DVCProHD100 codec ? – can’t see it in my menu..
