Perhaps --restrict-filenames could be changed to also handle the case when filename is too long?

workaround is to use --id:

This issue affects a large number of twitter videos as youtube-dl attempts to use the full tweet as the filename. EXT4, NTFS, and HFS support only 255 characters per filename, but the current max-tweet is 280 characters.

Truncating filenames to 255 characters (including extension) should fix "File name too long" in all conceivable use cases.
