Make a tutorial video/screencast for how to merge Releases in MusicBrainz [HARD]
Make a video targeted for uploading to the MetaBrainz YouTube channel that goes through how to merge Releases in MusicBrainz. Have a look through the how to for which things to cover at a minimum, but don't just read it aloud verbatim. You may also want to touch on some of the reasons for why/when merging is preferable to other ways of dealing with duplicate data, such as deletion.
The video should be 10 minutes long at most (the shorter the sweeter).
Be sure to read the "Making videos" guide for what steps are expected to be done during this task.
The video should be made available for use by the MetaBrainz Foundation under the Creative Commons Attribution-ShareAlike license, so make sure you're not using assets (e.g., music) that are not compatible with this license. If assets you're using require you to use another Creative Commons license that might also be acceptable—discuss this with the mentors.
NOTE: This is a difficult and time consuming task. Don’t expect to do this in one go and do expect to spend several days of work on this task and have multiple iterations.
