Hello all,

I'm trying to upscale several Red Scarlet 4K shots, anywhere from 10 to 50% in my edit.

I'm wondering: does using detail preserving upscale even matter for 4K footage I upscale like say 10%? In other words, is it beneficial to use no matter the percentage of upscaling? When does it start mattering for Red 4K footage?

More importantly, is the effect even good? Ha.

Thanks.

This is an awfully subjective question.

Seriously, "good" is something only you will be able to determine.

Render a shot scaled 10% with regular scaling then render the same shot with the Detail-Preserving Upscale effect, slap them both in a composition and take a look. Turn the top one on and off and compare. Maybe even try the difference blending mode on the top one. See how much of a difference you notice.

Now try that at a much higher percentage of scaling and compare again.

Not necessarily. What are you DELIVERING? If, for example, you're delivering in HD, you have boatlads of additional resolution: you could re-frame almost every shot and re-scale nearly every shot....

...and it would all look as good as you could ever hope it to look.

I'm wondering why such upscaling would even be necessary. What is the resolution of the playback device? That's the determining factor.

I'm assuming he wants to upscale to reframe the shots. But like you said, it's impossible to determine if there will be any quality loss without knowing what the final resolution will be.

Yup, it's all about the resolution of the final product.

This discussion reminds me of a not-so-old trick.

Before almost every TV station went HD, standard-def ruled, but HD cameras were still coveted items for effects work. If you had a nice key wall, you'd turn the camera 90-degrees and shoot on-camera talent vertically on a key wall. Then in After Effects, you could begin on a head-to-toe wide shot, and just scale it up to a chest-up tight shot and not lose a lick of resolution. Very handy.

You can still pull off the same trick with a 4K camera if you work in HD.
