working with uncompressed video

Hi,

From the uk. I absolutely love the interace and facilities of Vegas. We use Vegas for pure audio applications as well as video. It absolutely rocks. The only thing that I would like to discuss, and this may well be addressed by sheer computing power and disk/media playback speed over the coming years, is how to use the Vegas interface to edit uncompressed or higher than DV quality, video.

Assuming that I can capture the video (?)as an less/uncompressed avi that Vegas can read how will it play it back? (Anyone have any thoughts on this?) Would a scsi disk array provide the speed required? Is there a threshold of CPU speed required?

Would members of the forum maybe edit with a compressed set of files then replace them with uncompressed files which would then be intergrated into the project and then render them as uncompressed but then how would you lay it back?

This posting also once again begs the question of the qualitative differences between formats. I understand that DV and DVCam have virtually the same picture quality the main difference being the way audio is better synced and a more robust tape.

I use Vegas for everything I do from Web to Broadcast, the results are fine for everything but would like to be able to 'up the ante for/to certain people by saying yes I can capture component, edit it and then lay it back....

Any thoughts? Are we talking semantics?

Thanks

Alex

I don't have any good means for getting uncompressed video into my computer; all i have for that is an ATI Rage Pro card with analog video in/out, but it will capture 720x480x24bit 29.97fps, more or less. Vegas has no trouble opening and working with these files. They are huge, almost 1.8GB/minute, but they work fine. I can capture and edit them on an 866MHz P3 with 256MB RAM.

I'm sure there is better capture hardware out there that would produce broadcast quality uncompressed captures. I can get DV captures from analog through a SONY DVMC-DA2 that are much better quality than the ATI's captures, so there really isn't much point in me using uncompressed.

Hi Alex,

There a few folks on the cow forum working with uncompressed.

You might search there for uncompressed or SDI to get some good info...

(I believe some folks do edit in DV, then swap files for UC prior to rendering too.)

Are you doing this for scientific/medical purposes? There are some lossless capture codecs out there that will give you the same results with out the inordinate system and disk space demands.

Thanks to those who responded to my posting, this is my first time out here and I am impressed.

I will certainly check out the Cow forum re compressed and would love to know more about the lossless codec....I am working on a variety of things from multicamera band shoots to corporate stuff. I just got back from Vegas a couple of days ago where I was filming then editing with Vegas and uploading to my server as a WMV file. I just love this program, so happy not to be using Avid.

I am seeing that Vegas will recognise an analogue card,(Possibly an SDI input?) just got to figure out which one to get for best quality capture with quality codec but first stop - the Cow forum

Good luck everyone

boyesen,

I switched to the Canopus ADVC-100 from analog capture and I am much happier with the quality. If you absolutely need to capture analog, look for the hufyv codec to get lossless avi.

oops, make that "huffyv" not "hufyv"...
