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.

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 :apple: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.

Yeah, artwork can be added to the meta data by Stubler. iTunes uses that as the poster, dunno what other apps do with artwork in the metadata.

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

OMG thank you for this. Now I can give my client the finished video.

The poster frame feature was dropped even from FCP. Plenty of complaining. But subler works very well for this kind of things. I've been using it for years to tag videos with a number of things.

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.

What app are you using on the appletv? That doesn’t look like one of the apple apps.

Then it's a VLC issue. Artworks in mp4 inserted with Subler works fine in Apple software. Report a bug to VLC or ask them for help.
VLC right now is probably getting the data directly from TheMovieDB or similar.
