Construct archive file from video that have already been downloaded into a directory?

[jeffreyschultz]

Anyway to create the archive file after-the-fact if you have a directory of videos, instead of having to use the option before-hand?

Just run the same command you've used to download these videos with plus --download-archive - it will skip the actual downloading. Alternatively if you have ids in filenames - write a script that will extract them and put in an archive.
