How much can you zoom in 4K to 2K filmout

[Manuel puig lopez]

Hi guys, I am editing a short film on FC and in some scenes the coverage is to short and I was thinking in reframing/zooming some shots. How much can I zoom in until I get to 2K or even more if it not to noticeable.

Thank in advance from a new user of this forum.

Not at all in FCS, but you can zoom in with RA/RR up to about 150% with full decode.

Try a 2K crop of your 4K footage in RC, it will show you how much you can zoom in... Cropping will allow you to stay in the 4K image without downsizig it. For a zoom effect, my guess would be to import 4K footage in a 2K project in AE and then zoom in wherever/however you want, if that's a zoom effect you want... You'd then keep the 4K quality in a 2K output... It's a bit tricky but should work and preserve. If it's just a matter of "reframing" a 4K image, without a proper "zoom" motion, then cropping in RC seems the best way... Then again, I don't know what you wish to achieve exactly.

On a tip stand point, I can say that I'm often making zoom effects in FCP, thus blowing up the footage, and before you can notce a degradation in quality, you have a very acceptable margin... Nobody really notices unless you zoom too much, say to a crazy pixellated level :)

Thanks guys, As I said, footage was originated on 4K(2:1), framed to cinemascope(2.35:1), there is pixel loss already here, would be nice to know how many, and final output is gonna be, 2k, I am editing with prores tobe able to see effects and to be able to see zooms, I am using a 150 zoom and one or two at 200.

All this as reference as I am gonna be finishing in a Baselight and would replicate all the effects there.

Thanks again from a new user to the forum and apologies if this is already here in the forum

Just to be clear if I am doing it right (please say yes or no):

I am editing ProRes1920 on Final Cut.
I crop 200 percent into an image. I can see quite a resolution loss.
I go to Shake (dont have AE) and load a "Full" proxie and replicate the crop there.
Render out to ProRes1920, import into FC and replace the shot.

Ok??

All the best,

Jochen
