iPhone heic videos - suppress or filter?

iPhone heic images often come with associated videos. If I download someone’s iPhone heic images, I get a *.heic file and a *.mov file.

Is there a way (in DigiKam) to suppress or filter only the downloaded *.mov files that are associated with *.heic images?
But not filter/suppress any video *.mov files that were deliberately captured?

For example, is there a way (in DK) to filter/suppress videos of (say) 3 seconds and less?
