I am making a short video for a website for the homepage. I need it to be a custom size to fit the specific area (556px x 323px). My comp is the correct size, but whenever I render it, it renders it to a different aspect ratio making it 673px x 323px. I am relatively new to AE so I'm not too familiar with render settings and how to have a custom aspect ratio. How can I render out my video at the same size/aspect ratio as the composition? (I've tried clicking resize and locking the aspect ratio, but this didn't work).
I would appreciate any insight! Thank you!
Here's a screen shot of the "output module" settings I've tried as well as the "format options"
Check your composition settings again and make sure that you're set to use "Square Pixels." My guess is that you're not.
Assuming that you've been working at another Pixel Aspect Ratio (1.21?) your composition probably looks okay as is in AE and you probably can't simply switch the composition to Square Pixel now (it will make things look stretched out).
If that's the case then you'll need to create a new 556 x 323 composition with Square Pixels, drag your old composition into it, then with your old composition selected go to Layer > Transform > Fit To Comp.
Everything should look good in your new square pixel comp now. Use the square pixel comp to render.
