Proper Render size for TV output

Proper Render size for TV output

Proper Render size for TV output

Hi again
I have always rendered animated frames at 640x480 but someone told me that was the wrong size for standard TV output, He didn't know the actual render size. Can anyone help?

RE: Proper Render size for TV output

hello !

you are right to work in 640 480 with a pixel ration of 1...
this is for a "basic" ntsc
but there is other format... like NTSC DV wide screen, NTSC D1 with a pixel ratio of 1  or a pixel ratio of 0.9...
For TV work, today in my post production company, the final output we deliver is  720/486  with a pixel ratio of 0.9.

and when i work with video footage comming from a inferno grab,  i use this setup.

 but if I need to create an animated sequence with footage that i create in illustrator, flash, photoshop, my setup is 720*540 pixel ratio 1.0,  and after i comp the final work in a 720 486 pixel ratio 0.9 , by applying a 90% scale on X and Y it fit the comp perfectly.

with this method the circle shape doesn t look like a oval and the square to a rectangle on the computer screen.

for graphic animation with very thin edge, if your computer allow you to do so, i would suggest you to double the resolution  of 720*540 and after do the scale to video res output. this can avoid hard edge on high contrast area of the screen by creating a "natural" blur with the scale.

I really hope this will help you !
feel free to ask again things that seem obscure!
because i am french and my english not so good...

last tips
when you render or setup a composition in after effect, there is something called PRESET to help you to choose what you need.

good luck!
