Depending on the settings of your instance, you might be able to upload videos directly into PieFed. I don’t know of any instances that allow that because of the storage problem but if you’re self-hosting your own then the only storage being used by local videos will be ones you put there yourself.

Also, PeerTube works. You can add any PeerTube channel as a community (e.g. https://piefed.social/c/piefed_announcements@peertube.wtf is the PieFed view of the original channel at https://peertube.wtf/c/piefed_announcements) and then cross-post from there into whichever Lemmy/PF community you want.
