Okay, I just got done shooting a music video. A-camera HVX, B-camera DVX.
I shot everything 480i 24pa squeeze on the Hvx so we wouldn't have to render when trying to edit it with the dvx footage. The problem is that we also shot multiple slow-mo takes at 720 24pn. I want to be able to edit without rendering.
Ideally rendering isn't very practicle for our music video situations because we shot 5 different individual takes for each band member plus the whole band as well. Our editor views all five clips at the same time and would have to render after each cut.

I've tried to media manage a 720 file and compress it to ntsc. It looks pretty bad.
The other option I'm going to try is print to tape (dv) from the 720 footage and and then capture that into the existing files and edit everything in dv ntsc sequence.


My questions are.

1. Has anyone shot using the hvx and dvx for a and b camera's. What was your workflow for post?

2. Is there anyway in the future to shoot all of the HVX stuff HD and still intercut dv footage without rendering.

3. Does anyone have any suggestions on how to make this situation any smoother for the future?

I will post the video when it's done. It looks pretty good. We shot in a old dirty warehouse with a metal band. we shoot narrative for the story part of the video tomorrow.

Please help...

Downrez the HD stuff to DV in-camera, and then digitize the resulting DV footage. That way you'll be working with only DV all the time.

Set the P2/Tape switch to TAPE, then go to PC/DUB mode. You can select which clips you want dubbed over, and select the pulldown sequence you want to use, and then execute it and it'll convert the HD down to DV. You can then digitize that tape just like you did the DVX tapes.

With advanced pulldown - because you stated above that the footage was 24pa

Depends on what pulldown you choose to apply when downrezzing. I'd advise using 24pA pulldown if you know you're going to be editing in a 24p timeline.

Dubbing to tape is going to be time consuming. If I shoot 20mins of 720pn, then I would have to wait 20 mins while it dubbs. I guess having the dvx as b-camera doing some shots while down converting on the hvx would be possible but I wouldn't be able to shoot 2 cameras at the same time.

Is there any othere way of doing this without dubbing to tape.

this might work. the hvx and p2 cards can do a log and capture through firewire, the principle is the same as tape. do a capture of the 720p footage. the device control is the hd firewire, but for the codec switch it from dvcpro hd to "dv ntsc". see if that works..

If you already have the 720 footage on your computer, I'm sure you could use Compressor to batch convert all your 720 footage to 24p DV. Hit go and come back when it's all done.
