With adaptive resolution on, anamorphic footage flips and stretches while scrubbing

[Eugene Mogrts]

It is an old-time bug still present in 2023 I've experienced it in around 2016 when I encountered with the anamorphic shooting for the first time.

When the adaptive resolution is switched on in the compositing panel, anamorphic footage that is within it flips and stretches itself while scrubbing or dragging playhead.

Steps to reproduce:

1) Insert any red anamorphic footage like 6k with 12:5 squeezing ratio (could be any different from square pixels) into the new composition

2) Set to adaptive resolution in the composition panel

3) try to grab the timecode to shift time or grab the playhead and drag

4) Also you can either try different render resoulutions in composition panel or in Edit -> Preferences -> Preview and try changing the adaptive res limit like to 1/16 and try to srub the footage and see how differently it behave with different limits...

Thanks for reporting this. I've created an internal bug ticket for this so we can take a look further.

@Eugene Mogrts Are you able to share the footage with us? Just want to make sure we are reproducing this as you are. Thanks.

[Eugene Mogrts]

Sure, let me do this later today, as soon as I get home

Thank you for the files. I can definitely reproduce the issue. Will look at what's going on further.

I also find these tweaks in the preferences file work a lot better for revealing the rendered image while scrubbing
