relationship btwn Camera and Comp sizes
Hello all. I feel like I should know this after so much experimentation but I am thoroughly confused right now…
What would be the science behind the camera settings when going from the HDTV comp preset to ntsc DV preset? I have some complicated 3D projects where everything was built using the HDTV preset. I’d like to downconvert the project and rerender but ofcourse when I simply change comp settings, my view of the 3D world shrinks dramatically. up until now I have been simply “eyeballing” new camera settings to re-frame things.
I’d like to know if there is some math I can use to apply new camera settings to go with the new comp settings so that I’m basically dealing with the closest rendered output in the end (ignoring ofcourse the diff between 16:9 and 4:3).
Thanks. whew.

ok just did another one… in the HDTV version of the project, the 3D camera zoom is at 1000. after changing comp settings to ntsc DV 720×480, i had to set the camera zoom to 350 to get what seems to be the same framing. Thanks for any help people.

Just drop your HD comp into an SD comp and scale the comp size using the normal scale parameter.

Yeah, that works but then all processing is happening at 1920×1080 resulting is super long rendering. by changing project settings for all comps to 720×480 rendering times change drastically. Eyeballing it isn’t sooo bad but I thought someone could explain the science of the camera to me… thanks for the replies.
