Topaz Video - Starlight HQ bug

1.5.0 has a bug exporting a video to Starlight HQ if crop is enabled; pre-cropping and then exporting works fine.

The actual crash is this Python traceback:

File “…/AstraHQ.parse_ffmpeg_filters”
AttributeError: ‘list’ object has no attribute ‘split’

Crop filter triggered it --ffmpeg-preproc-filters crop=w=318:h=360:x=0:y=0

This is a bug in how Topaz passes arguments to the AstraHQ model when cropping is enabled. Disabling crop is a workaround; starlight-precise 2.5 and starlight mini worked fine with the crop.

Thank you for reporting this, we are replicating and sharing with the devs for review to get it patched.
