I have a long show to shoot (4+ HRS) on 3 cameras. Two of the cameras must be unattended and locked down on wide shots. The third, I can stay with. The cameras are the JVC GY-HM100u (2 cameras) and one JVC GY-HM600. The data usage for the HM100's will only get 1:53:00 of time per 32 GB SDHC card if I shoot at 1920 X 1080 30p. If I change that to 1440 X 1080 60i I will get 2:37:00 on each SDHC card and I will get the whole show on 2 SDHC cards. The JVC GY-HM600 can be changed to match the HM100s. The question is this:
If the ultimate goal is to have the show rendered to a DVD set, will the difference in resolution result in an obviously inferior product? I realize that the higher the resolution usually makes for a more crisp video. But, if I shoot at the lower resolution, will the subsequent DVD set suffer?
Thanks for anyone that can assist with this.
BTW, I will be editing with Sony Vegas Pro 12 and have several options as to rendering.

I've shot with HDV cameras at their native 1440x1080 resolution for many years. This will have NO impact on the DVD quality, which is knocked down to 720x480 anyways.

Even if you wanted to post the finished video online (like YouTube) you can edit in a 1920x1080 project, using 1920x1080-quality titles and graphics, and just export as 1920x1080 then. No worries, will look good.

Thanks

I had an HDV camera. One thing I occasionally ran into was when creating text graphics, then exporting, the aspect ratio of the text would be thrown off & look awkward because when you're exporting you're taking narrow pixels & making them square (or something like that). There were ways to overcome it, you just had to use a certain workflow (tbh I think it was when I was using After effects anyway, not Premiere)

Just something to think of, if you're planning on alot of graphics is may be a concern or you might wanna test out your workflow & software in advance to test how it handles it.

Lots of my stuff includes archive footage - so I shoot and edit these in 720, and SD going up and 1080 going down are seamless going into DVD, and entering out 1080 versions leaves the 720 pretty good, and just the sd a bit soft.

David and Jeff,

Thanks for the replies. That takes a load off my mind.

And, Thanks Paul.

I edit with Adobe Premiere, and it is smart enough to figure out the pixel aspect ratio differences. If I edited in a 1440x1080 project, I could still create my Photoshop graphics at 1920x1080 (1.0 PAR) and drop those into the 1440x1080 project (1.333 PAR) and they looked perfect. And likewise, dropping 1440x1080 footage into 1920x1080 project sequence looked fine, all compensated for automatically, so I had no issues ever in that regard. Was all transparent to deal with.

Thanks
