How to render just a certain section of pixels in AfterEffects

[LarissaBlu]

Hi,

I am starting to create this big composition which has 9 screens next to each othe at the same time.  (1080x20200px)

For editing reasons I need them side by side all at once.

But for the export I would have to render just parts. Either the 9 sections or 3 sections together.

3 years ago I had to do a similar thing so I know it works... I just forgot the steps and I can't find any info.

thanks in advance for the help and I hope I have expressed the problem accurately 🙂

You would simply nest the relevant segments in yet another comp for output. if they follow standard broadcast specs you should not have much trouble figuring out the math. If you need a smaller, irregular section, the Region of Interest and the respective Crop to Region of interest... in the Composition menu are your friend.

Thank you so much for answering! That makes so much sense. 

All the best
