I love czkawka (and it's new replacement, krokiet), but specifically for video, I prefer Video Duplicate Finder. It has more flexible adjustment options, and a better UI with more information (comparing file sizes, bit rates, resolutions, durations etc. right in the listings along with picture previews). It's available cross-platform, here's the GitHub: https://github.com/0x90d/videoduplicatefinder

Especially for high-production or just high-quality scenes (4K scenes or longer movies), re-encoding to AV1 (and depending on the original audio codec and bitrate used, re-encoding the audio to a more efficient codec like Opus as well) can save a lot of storage space and make them easier to download and access for members. The same is true for large collections that can take up a lot of space, but if re-encoded, even if every individual file doesn't shrink by that much, the overall size shrink can be significant. So I wanted to ask if downloading existing torrents, re-encoding the video to save file size, and re-uploading them is considered uploading duplicates, or if the re-encoding is considered transformative enough to count as a unique torrent?
