Which is better, recording in 16:9 mode or editing to 16:9?
It’s best to work in one format or aspect ratio when you can.
If you shoot in 4:3 then you should edit and output to 4:3.
If your camera is native 16:9 [meaning your chip/s have a 16:9 aspect ratio] then you should shoot it, edit it in 16:9 and output in the same.
Most everything is moving to 16:9 so you’ll find/have many options to work with.
I agree with what hidef1080 had said.
When you shoot in 16:9 and edit in 16:9 there will be no lost on the video quality.
Currently I am shooting in 16:9 regularly, so when I burn it to DVD to my friends I make 2 verison. One is for the Wide screen format TV and the other I convert to 4:3 with the 2 black bar on top and bottom of the video during the rendering. All my edit I use 16:9 format.
I got good feedback from the viewer, for those who are using 4:3 format TV they feel that the wide format give them a film look.
