Video Editing (NLE): Time results of rendering in non-native resolution I understand (I believe) that when I select a resolution smaller than my native, pixels are dropped from each frame. I'm wondering how much of a burden this is on my CPU.

I have a 1440p monitor, options to downscale resolution in Dxtory (recording gameplay), and options to downscale resolution in Blender when rendering. Would it be best for me to downscale when writing to file from Dxtory? Or perhaps, to downscale when rendering in Blender? Or (doubtful), would it simply be less hassle to write to file and render in 1440p?

Essentially, if I'm only going to do one (which I assume is the best method), when should I do it?

Thank you.
Blender's VSE always scales the image, unless the source is the same size as project.

The project's render properties determine the speed of the scale process.
In the properties panel look for Anti-Aliasing.



For best speed of scale turn this off. However the image will have jagged edges.



To improve quality of the VSE scaling or other transform effects, you must turn on the Anti-aliasing. There are many levels and algorithms to choose from. The render-speed change may not seem to great, but you must multiply the difference out over the total number of frames rendered. And this example was based on a very simple image.
