Very special case. But you can save the import part. However, some manual steps are required:
Copy the pq1-amiga.svm to the ~/RetroPie/roms/amiga/ folder.
Find the Amiga video (I guess you already did that).
e.g, https://www.screenscraper.fr/gameinfos.php?gameid=34415&action=onglet&zone=gameinfosmedias
Navigate to the ROM/ISOs latch and pick a checksum and use it in the query parameter.
Run Skyscraper -p amiga -d /tmp --flags videos -s screenscraper --query="md5=2c4827513db0e45eed77d20d290fa17d" ~/RetroPie/roms/amiga/pq1-amiga.svm.
Find the video for "Police Quest" from screenscraper in the scummvm Skyscraper DB file, usually ~/.skyscraper/cache/scummvm/db.xml (type="video" source="screenscraper" with the matching resource id for Policy Quest). Note the resource id.
Copy the amiga video into the scummvm cache, e.g.:
cp /tmp/videos/screenscraper/494148112002ee474500cc10cbd212b1dedc5bd0.mp4 ~/.skyscraper/cache/scummvm/videos/<just-noted-resource-id>.mp4
It could be that the resource id is identical between Amiga and ScummVM, as the Skyscraper resource id is calculated from the filename and not from the file content for *.svm files. I did not verify this, but I assume it will be the case.
