[BUG] 1st-pass stuck with SSIMD.

[DevSker]

Without details (encoder settings etc.) -> no clue.
Can't say anything atm. without a debug output.

on a first try the preview failded for me since

clip = core.resize.Bicubic(clip, matrix_in_s="2020cl",range_s="limited")

complained about:

Resize error: Resize error 3074: invalid colorspace definition (10/2/2 => 0/2/2). May need to specify additional colorspace parameters.

I know what's causing this and can fix this, but I have no clue whether this is related to your issue.
Will look at it  after work.

Cu Selur

Sorry, I forgot about the debug output, it's attached.

Extra info: Also, I did the exact same steps but added "Scale output frame rate" to 30, and now the progress bar is stuck at 197.62%(?)
