Render 360p from 1080p project (Easy Way)

[sergiob83995711]

So, I have a bunch of 1080p projects, and I want to render them as 360p.

Of course I can create a new 640x360p composition put the original composition into it and scale to 33,3% but it will ONLY scale that composition and the render time will be the same as rendering 1080p.

Tried with the "Scale composition" script that comes with After Effects... Does exactly the same thing, it do not rescale all the tree of compositions and solids, only the last composition and the renderingg time will be the same as 1080p.

Any easy/fast solution?

I found that I can scale the whole thing down in the "Render Settings" by changing the "Resolutions" to "Custom" and  "Render every 3 pixels horizontally and vertically". If fixed the render time for 360, but I can't use "1,5" or "1.5" (because half pixels is not a thing) so I can't do the same for 720p.

Any ideas?

Simply set the resolution to Half From render settings to get a 360p from 720p

and to get 360p from 1080p simply set the resolution to third

What about 720p?

Why not just create a 360p preset in Adobe Media Encoder and send all your renders there?

Doing that is the same as puting comp and scalling it - AE have to count and full res and then scale it. By using half/quater res - AE is just counting that resoulution. F.eg. by my testing - fairly simple particular blurry animated snowy background 10 sec length, full hd composition
- main full hd composition in smaller composition (480x270px) - render time 1min 6 sec
- main composition rendered as quater resolution (final rendered video the same resolution as above 480x270px) - render time 17 sec
