Quote:And "Enable" - switches back to original previous selected scan type.

... and there is the problem since that would requite to remember some old state, which is something Hybrid does not do by design.
So enabling the option would only do that enable the option, scan type would still be progressive.

Question: Does MacOS come with python3 or did I install it on my vm somewhere along the line?

Cu Selur

When i attempt to use installation fix for newer versions of Vulcan and run command that use "sudo python3 " as it was described here https://github.com/KhronosGroup/MoltenVK...-886281938 - nothing happens. This makes me guess that there is no preinstalled python3 on my system. But note that i still use legacy macOS 10.14.6.

Okay, thanks for the info.

Seems a little bug with Letterbox, or i am doing something wrong:
- import video
- enable Letterbox and it set to 1920x1080
- import new video
- Problem: Letterbox changes to something like 29766x1080. Seems that new Letterbox size somehow depends of input aspect ratio.
It is easy to reproduce. Should i send you a debug?

My Crop settings:

Lower border for letterboxing should be the resize resolution.
If the resize resolution stays the same, so should the letterbox.
Will look at it later.

Letterbox also sometimes changes when i change settings in "Crop". This is really looks strange because user expect Letterbox as a simply fixed defined frame that not affected by other settings.

Also if i use "Crop" and then disable and enable Letterbox, it resets width to cropped size. So i need type 1920x1080 letterbox size again there.

---

Also maybe it was asked later, but why it is impossible to save settings as preset for Crop/Resize tab?

The order is:
Input < Crop < Resize < Letterbox
- Crop has the input resolution as upper boundary
- Resize is based on the crop resolution and the PAR
- Letterbox has the resize resolution as lower boundary
so if:
- resize isn't enabled, lower boundary for letterbox is the crop resolution
- if neither crop not resize is enabled the lower boundary for the letterbox is the input resolution

Sorry, but that does not make sense the way letterbox usually works.

So, if you load a source and 'keep resize for new source' isn't enabled and the input resolution is greater than the letterbox the letterbox naturally needs to be adjusted to the input resolution.

Yep, if everything is so connected, it is no surprise that Letterbox may be changed.
But it don't explain why Letterbox changes to 23040x1080 when i import .MP4 720x576 that have 15:16 PAR
And it feels like something very random.
For example if i import 1920x1080 video - Letterbox changes to 5760x1080.
If i import some other 1920x1080 video - Letterbox keeps size 1920x1080.
If i import some other 1920x1080 video - Letterbox changes to 3600x1080

I guess it is something related to some metadata in video container. Or it may simply some bug that change things randomly.

Sounds like the letterbox gets adjusted by the PAR.
Looks like the input PAR 16:15 get's applied as 16/1 which cuases the problem.
-> will look at it after work.
