720p vs 1080p in terms of render times

[High1ander]

I have read that the difference in resolution between 720p and 1080 on the HVX200 is about 20%.

But how much longer time does it take to render stuff in Premiere and After Effects?

I am gonna do a short that will be directly geared to to a film festival which might show it on the big screen. So I would like to have the possibility to shot 1080p, however if it is like 4 times more time consuming in editing, etc. then I might reconsider.

I will do, CC, add 3D-animations, composites and so which has it pros and cons for larger originals.

My gut says 720p, but my pride says 1080p.

edit: When I do the math on pixeldifference, then 960*1280 and 1280*1080 sums up to, first 691200 and then 1382400. Which means that 1080 is twice as much in terms of pixels. Which I guess should equate to 4 times the render time, however, where is the 20% resolution difference from? Is it resolution charts?

It should take twice as long to render, since it's twice the number of pixels (assuming the same frame rate, meaning 24P to 24P; if you're comparing 720/60p to 1080/60i, they should take the same time to render.)

The res difference comes from the fact that the HVX can generate more detail than 720p can record, but not enough to fully take advantage of all that 1080p can record. It's somewhere in between.
