How to Solve the “Poster Frame” Problem

izzyvideo 347 frame

I received an email question about poster frames the other day, so I thought I’d make a video that shows how to solve a problem you might encounter with them.

The problem is basically this: When you have a video file on your computer, the operating system automatically chooses a poster frame to represent the video file.

The poster frame is a single frame from the video. Sometimes the frame the operating system chooses is great. Other times, it’s not ideal.

And the challenge is that not all apps allow you to choose your own custom poster frame when you export a video. For example, Final Cut Pro X doesn’t let you choose the poster frame when you export a project.

That said, there are ways of dealing with this. In the video, you’ll see me use a couple different options for setting a custom poster frame. One of the options feels like a hack, but it can get the job done.

If you’re someone who stores video files on your Mac, and you like to see a good visual representation of those videos, this quick tip should be useful.

  1. Another excellent video, would you be open to sharing your compressor settings for your MP4 1080, 720 and 360 encodes?

    1. Hi Steve. Thanks, and yes I’ll put that down as a possible upcoming article. :)

  2. Great video! I solved the poster frame problem for my purposes by adding a single frame at the very beginning of my project, in fcpx before exporting the video. It worked for me (e.g. iOS video posters), but I dont know, if this is always shown up in other applications like e.g. finder.

    1. Thanks, I’m glad you liked it!

      My experience is that the MacOS will automatically select a poster frame exactly 10 seconds into the video file. If the video is less than 10 seconds long, it selects a frame halfway through (from what I can tell).

  3. Thanks Izzy. More stuff learned today!

    1. Glad to hear it, Gil!

  4. Hey Iz…

    Great stuff! But here is a real world issue…any ideas on how to set a poster frame that will hold up on Facebook (for example). We post a lot of vids for our clients on FB and always have to pull a still of what would be the poster frame to post separately as a custom thumbnail. Any idea how to export & post a video on FB with a poster frame set that FB will recognize?

    1. Mike, I’m not aware of a way to do that. I do the same thing as you — upload a separate image for the poster frame.

      1. If all else fails, you could post your movie to Vimeo, which has a ‘choose poster frame’ facility, then use that as your Facebook reference either by downloading it or by referencing it.

  5. How the heck did you figure all that out?!!
    I’m impressed.

    1. Thanks, Joe! I’m glad you like it. :)

  6. Great tips, thanks. However, you can set a thumbnail in FCPX. Place the playhead on the selected frame you want, then export. The frame the playhead is currently on will be the thumbnail.

    1. Hey Bruce, thanks for the note. Strange, when I tested that myself the other day, it didn’t work for me. I was exporting a Prores file. I’ll try testing other formats to see if that works.

    2. Okay, I just tested it again exporting both with Prores and the Apple Devices preset, and it didn’t work. When I look at the files in Finder using the Icon View, the poster frames are the standard, automatic frames generated at the 10 second mark. When you look at the file in the Finder, the poster frame is the one you had the playhead on when you exported? That’s not working on my system. Maybe someone else reading this can test this too?

    3. Same thing for me. No change. I just tried with ProRes export myself. The position of the playhead determines the image in the export window, but does not seem to make any difference in the .MOV file that shows up.

      1. Same result I’m getting. I’m not sure why it seems to work for some, but not for others. Thanks for testing it! :)

  7. Nice tips Izzy.
    Quicktime 7 has an option under the view menu to “Set Poster Frame”.
    Looks like finder ignores it if you simply “save” or “save as”. However the new poster frame displays properly in Finder if I used QT7 to “Export” to a Quicktime movie. The play button also works if you roll the mouse over this exported file in Finder.

  8. Thanks Izzy! That was something I wondered about.

  9. I go with Bruce. There’s a direct connection between were you left the playhead in the timeline when you choose the share destination window and what will show up in that window and later as a poster frame
    The great thing with your tip, Izzy, is that it solves how, if you must, to change it afterwards. Thanks.

    1. Thanks for the comment, Jan! For some reason, that process doesn’t work for me. Not sure why it’s inconsistent. Strange.

  10. Ok, yesterday I tested it and the playhead dictated what the thumbnail was, today I have the same results as Izzy. Strange.
