Playblast same size as render

[brooney]

I am looking to playblast files and later replace footage in AE with the rendered images.  Right now the Render images are coming in at a different size as the playblast.  Is this possible?

You can set the size in the playblast options. Either specify a custom size or set Display Size: to From Render Settings.

Thats where the issue is.  I am using From Render Settings and it is not matching up in post.

make sure you turn off your frame/title/action safe boxes and that your camera view is the only view open, then click the use render setting box (or specify your own settings in the custom field). Also, you can't playblast an area bigger than your viewport. So for example if you want a 1920 x 1080 output but your screen area only goes up to 1600 x 1200... you're out of luck.

Not quite. You can make a low quality hardware render in the background. should be more or less the same speed but has no size restriction.
