Problems with render!
Hello,
I’m with a technical problem.
I had created a project with all compositions in NTSC DV default settings.
I Added to Render Queue, selected Best Render Settings & Lossless Output Module and Rendered it.
But the avi file it generates isn’t in the same size of the composition. The video looks squared and all the elements distorted.I’d checked the file info and there is everything OK. (720×480)
But when I run it in any player still looks the file is in a different proportion.Anyone have an idea what’s going on?
Maybe something about the Pixel Aspect Ratio???I hope somebody help me.
Thanks & bests.
Fabricio.

Hi Fabricio,
NTSC DV uses non square pixels (0.9), but your monitor uses square pixels (1). For this reason, AE gives you the option of viewing your comp with pixel aspect ratio correction on or off (viewing in square pixels which is clearer on the screen, or in non-square so you can see the aspect ratio as it will appear on a TV). See the button on the bottom right of the composition panel that looks like a square with an arrow on top?
This button will not affect how the comp is rendered. It will always be rendered according it its settings (ctrl+k to see them). The correction is just for viewing purposes.
Now, when you have the rendered video the pixels will be 0.9 – but some video players do not make corrections for aspect ratio and will play in square pixels. Quicktime, for example, will appear to squash the video horizontally because it displays in square pixels.
Perhaps the difference you perceive is due to your not setting the correction in AE (so you were used to it appearing squashed, and now your video is played correctly it looks stretched), or it could be due to your player squashing the video (you were used to it appearing in proper DV aspect ratio in AE because the correction was toggled on).
Anyway, hope this helps. The bottom line is that if you have rendered a video according to DV NTSC settings, it will be fine for broadcast on US television.
