You actually build your video collections on
Huzzaz, which lets you add YouTube/Vimeo video links, search YouTube/Vimeo at the same time, import YouTube playlists, and even add YouTube/Vimeo videos from other websites/blogs using a bookmarklet.
Then you embed the video collections wherever you want. Once you embed the video gallery, you don't have to touch the code again. You can organize the video gallery on Huzzaz using a pinterest-style interface or just using the bookmarklet so you never even have to go to Huzzaz either and the video gallery automatically updates.
Another bonus is that you can set it up so that the youtube videos will play in 1080p instead of the default.
