👏👏👏 Love a nerdy breakdown for reasons that may seem counter intuitive! Awesome video for the info (how to desqueeze) but also awesome background and explanation. Chefs kiss
Great explanation man! It makes me want to shoot with anamorphic lenses now, although I don't own any. 😂 The short clips you showed look amazing though. When do we see the travel film for wherever that was? 😉
Thanks so much, Brad! I'm going to start working on it in the next couple of weeks, but I'm not sure what it's going to become yet or if it'll even make it on the channel. The review for this particular lens with a ton of B-roll will be posted either next week or the following week though.
I believe it's because when downscaling, you're cutting away resolution. Whereas with upscaling, you're not cutting away any of the original 4k resolution. You’re actually adding to it by expanding the resolution width through the process of interpolation. However because it’s just the software guessing how to add more pixels, it can lead to some quality loss. Less than downscaling which actually cuts resolution though
when you downscale the vertical dimension, you are discarding vertical pixels, you are throwing away information -- but on top of that, you are *still* stretching the horizontal pixels, which forces the NLE to interpolate that information. it makes intuitive sense, to me anyway, that it is better to leave the vertical pixels completely intact -- to retain all of that information. therefore ONLY modifying the horizontal pixels, which as the footage shows, results in a sharper image with less artifacts.
