are there any benefits to
Capturing HDV tape via an HD/SDI and RS-422 rather than a firewire as the footage is so heavily compressed as it is? I’m sure there is a reason, I just can’t see one, please prove me wrong.
Much Thanks, Matt

We convert all HDV material to ProRes by capturing via HD-SDI through our AJA Kona 3 boards. Why? Because HDV is a mess of a format to edit with being a Long GOP format.
In addition, all graphics and titles that are added to the timeline remain crisp and clean instead of getting hit with the heavy HDV compression.
And finally, we can work in full raster square pixel 1920×1080 instead of anamorphic 1440×1080. Makes it easier to create graphics and work in third party programs.

Hi Walter,
Thanks for the response.
Can you not capture prores 422 via the firewire out on a deck?
-
Yes you can, I do it al the time.

[matt shires] “Can you not capture prores 422 via the firewire out on a deck?”
absolutely, but it remains anamorphic instead of full raster. This creates issues, especially if you want to use Color.

Once it’s all captured is it possible to bring it up to full raster in compressor? or will this degrade the picture?

If you have the time to sit and wait for this to happen, you probably can. I have never tried this.

Hey Walter,
I have to disagree with your comments 100%. Native HDV is very easy to edit and even key if you have a Quad Core system. I know everyone that uses FCP brags about the 4:4:4: color space of the Pro Res as opposed to a 4:1:1 color space of HDV. While I will admit 4:4:4: is better than 4:1:1 all PC programs can key just fine with 4:1:1 codecs so should FCP.
I can put the HDV codec in a P2 project timeline or even a custom uncompressed 1920 X 1080 timeline. The realtime is still there. My video link below should prove this.

The Mac Pro along with FCP should edit native HDV with ease. Perhaps FCP can do it but if it can why make use of the Apple Pro Res? You are just going to make a bigger video file than the native HDV video file. I have a medicore $600.00 Quad Core PC not a $2500.00 Mac Pro.
