Shoot HDV for SD Delivery?
I'm just venturing into the "prosumer" HDV world and have a couple upcoming corporate projects... I'm curious if folks out there typically shoot HDV (with the A1) for SD delivery? There will be no HD version of the project needed.
Pretty much all my HD experience comes from the high-end world of the Panasonic Varicam and Sony F900 HDCAM. We shoot HD with these cameras for shows that are never seen in HD - mainly for archival reasons (future proofing), but also because the downconverts look so good. Kind of like shooting film for commercials, etc. never doing a film print, but starting with the highest quality and going down from there. Is this the same with HDV? Do the HDV downconverts hold up? Or should we simply shoot SD? And BTW, I'm not too worried about future proofing these shows, just want them too look their best. Thanks, Blake |
People thinking about the HDV->Sd always look at it from the wrong angle. The advantage of shooting higher quality and going lower later isn't just the downconverts (yes they look good, HDV to SD) but because of what you can do with the footage in HD as opposed to SD. The image is very crisp and clear, I think shooting HD is worth it.
Sometimes though I shoot SD because certain things in the video I might only be able to do in SD, to each his own. I think shooting in HD first is a better idea. - Kyle |
I would normally agree. But I just don't have experience working with HDV and the Long GOP media.
I prefer HD video even for SD for reasons like you say... for example you can zoom into a shot or reposition/reframe something. Thanks for the feedback. |
Pluses: better image quality

Which NLE does realtime to DVD?
|
I use Avid Xpress Pro (with a Mojo box) and it's realtime as far as playing, editing, most effects, etc. and the HDV doesn't really seem to bog down the computer too much.
I have a Dual Xeon 3.4Ghz HP xw8200 workstation with 4 gigs of RAM. I have not output/exported HDV yet though, so I'm not sure about that. Also, I've tested transcoding the HDV to the DNxHD 145 codec (intra-frame compression) and that works great. I can also downconvert on the fly in realtime via my Mojo (with component or firewire out to a deck), but of course that's SD output and not HD. |

I will say if you wanted to simply burn a DVD to a set top burner with S-video in or firewire in you could play the video off the timeline directly into the DVD burner. I do this all the time for client approval dubs. But again, it's SD not HD. However, it is in realtime.

The challenge for me has been getting "good" SD DVDs from HDV. Just editing in Final Cut, Compressor to DVD Studio doesn't always produce good results.

Actually, if it's an option for you, i.e. if you have about 200-300GB of hard-disk space, you can render your timeline to uncompressed 720x480, and then encode it to MPEG2. That way you are avoiding one extra compression step.

My best results have been rendering to DV50 timeline or letting the camera downconvert and editing DV.
