@Tony,

Glad you found it helpful! Enjoy your video projects!

Also, there’s so much more you can explore with Linux for your video projects. Feel free to reach out if you have any questions along the way.

I’m fairly new to Linux and need to convert some .m4v files to .mp4. This webpage will help tremendously with the conversion and also opens the door to other cool video projects.

Thanks!

Elsewhere (https://larryjordan.com/articles/change-your-movies-poster-frame/) a solution was provided several years ago – Can I ask if you think this command (by PAJ) will work to change a movie files poster-image and hence finder icon on Big Sur in 2021

ffmpeg : ffmpeg -i in.mp4 -I yourposterimage.jpg -map 0 -map 1 -c copy -c:v:1 mjpeg -disposition:v:1 attached_pic out.mp4

in.mp4 = target movie file
yourposterimage = new image for poster
out.mp4 = new movie file w/ new image for poster&icon
-- (? or is it "attached_pic out.mp4")

Thanks

Try to understand the command syntax, it is easy. Give it a try. You can start by running the same commands in the guide.

thank you
