Chroma Key - HDV vs DV

L_Town wrote on 5/29/2009, 5:32 AM

I have an upcoming shoot and will be using a green screen (a bright screen sheet actually). What format is better to film in, HDV or DV? I know each has different color subsampling but don't know which one is better in regards to green screening. I will be using Sony Vegas 7.0.

Any suggestions? Thanks!

HDV is far superior to DV for chroma key. It's not only the color sampling but the 5x increase in resolution. Pull a key on both and see for yourself. You'll get a much cleaner key with HDV.

I did a comparison between NewBlueFX's Chroma Keyer and Sony's and NewBlue gave a much more usable key than Sony's.

I wanted to also try Cinegobs but I can't get it to work on my main editing station- just my laptop.

Just an FYI

I can get a much better key with Boris FX than I can with New Blue Video Essentials 2 or the stock Vegas chroma key filter. It's a pain the first time and a bit complicated to figure out, but once you have a couple of your own presets it is pretty simple after that.

I guess I need to try it out (Boris).

The link below will show you a key done from a less that perfect green screen background.

For the wide shots I used the NewBlue keyer and for the close-up shots I used the standard Vegas keyer. This was shot on a Canon GL2 standard def camera.

Depending on what you have to work with you may need to select the background that works best for your key.
