I've searched all over the internet and I can't find a solution that works. Basically after I finish editing my movie in iMovie and save the file, the program automatically picks an image from the video to display as a thumbnail and it looks terrible. How can I change which thumbnail iMovie decides to use? Thank you.
Got a tip for us?

You are talking about what are called poster frames? You can pick poster frames with QT pro, iTunes, or MPEG stream clip I think.
Also can be done on share/export in some versions of iMovie see this:
Later versions don't work, but for youtube you could do something like this:

I saw both of the videos already. The first video works with only old versions of iMovie and in the second video I don't share these videos on Youtube so it doesn't help.

If your goal is to have something that looks better on an 
TV screen, I suggest using MetaZ, Subler or a variety of other such tools and basically make your own poster. I usually shoot a few good photographs of anything I video and then use the photos to build an attractive poster. MetaZ, Subler or similar also lets me tag each video with description, dates, etc too.
I'm not sure that that is your objective here but if so, that's the way I'd do it if I was you.

I called Apple, They literally have no idea... I'm shocked.

Miltz, I’m wondering if you ever found a way of creating a poster frame for an mp4 you’ve created? I have been searching all over the place and can only find a way of doing so via iTunes and Subler, which is good but doesn’t address my problem.
I’m looking for a way of creating a poster frame for an mp4 file that will display in tvOS (the Apple TV 4K operating system). The Subler solution only works when the icons are viewed in iTunes.
What I’ve got is generally a group of blank icons, but there are a few exceptions where the file name (somehow) allows tvOS to locate a publicly available graphic for a movie and tvOS displays that. Screenshot attached.
If anyone could help that would be great.
Thanks.

Finally a answer that makes sense, doesn't use a 3rd party software, and works a treat, thank goodness for woodmantech. Just put your curser on the timeline in iMovie where you want the thumbnail and share it again, simplicity at its best.
