Aspectical Ratios

I always get myself turned around when trying to calculate percentages. Let me start from the beginning -- Adobe Premiere Pro does not have a letterbox plugin. This is irksome to me.

Vashi Visuals has some .png files to download with all the different aspect ratios at all sorts of resolutions

At first I thought that there were only 4K images in that download, which is cool but we shoot in 3840, so the image has to be ensmallened slightly. How much? Luckily there are calculators on the web for that.  The answer is 96%, which is how much I scaled the image to by eye, but it was nice to check the math.

That said, there are "ultra HD" .png files, I just didn't see them because they're at the end of the list and I can't read.

Remember Jarl's Premiere Presets? That's where they are.

Why would it need to have a letterbox option? Like, whatever aspect ratio you want to export, just start a sequence with those specs, then drag your original timeline INTO that sequence. Click on it and tell it Scale To Frame Size, and you're now exporting at whatever size/aspect ratio you want. Not sure why, nowadays, you'd wanna introduce fake letterboxing...

Our delivery specs are always 16x9, so "lines on the top and the bottom of the screen" are necessary if you want deliverables that are 1.77:1 but using (say) a 2.35:1 aspect ratio of actual picture.

I dunno, still don't get it. Export at 1920X1080, and that's 16x9 with no artificial letterboxing(so they ask for an aspect ratio, but don't specify a frame size?). And if your specs are 16X9, you're using an aspect ratio of 1.78, not 1.77, right?

I'm giving them 16x9 video, but with a letterbox so that the image itself is 2.35:1. At least that's what I want to do.

My head is exploding. So I think we can agree aspect ratios are just fucking confusing.

It's nice to have a little extra room on top and bottom in case I need to reframe to get actors' eyes in the right place.
