Well I download 4k video with it. However, I have been using it for a while so it is possible they have changed what you can do with the free version.Thanks looks good. Is it limited to low resolution though, as there's an advanced edition which says download HD?
This. It is so good that I gladly bought the paid version. Being able to download playlists... definitely worth it.I have been using 4K Video Downloader for a long time and it's by far the best I have seen:
It is free, offers a premium version (rather useless) but is not obnoxious about it and never nags you.
It lets you download any quality level and file format that is available for a particular video.
