Downscaling your footage

[rtf]

If you record in -say-1728x736 and put in a 1280x720 timeline (so you downscale your footage), will this still give higher quality footage than when you record it in 1280x544?

So in other words: is it worth recording as big as possible even if you downscale your footage afterwards?

yes. but

..as big as possible..

its a decision of memory consumption. the crop-mode delivers really good quality.

Alright.

I did a little test just now and the higher resolution (1728x736) has more detail than the smaller resolution (1280x544) - even when downscaled .

[chmee]

because its a bayer-patterned sensor, sensor-resolution and picture-detail differ. a bayer sensor with fi. 2000px horizontal cant differ 1000 pairs of lines. multiplicate it with about 1.41 (sqrt(2)) and you're somewhere in that region. in short words: to get a real detail resolution of 1280px hor you need about 1800px hor. (very simple described) thats why an arri alexa works with ~2880px - just to get real 2K detail-resolution.

and then you understand i say, "the bigger resolution the better" isnt generaly true, there's a point, it cant help anymore.

Great point @chmee!
