    Reszing MOV video with Alpha Channel

    Posted by Steve Wilson on August 6, 2015 at 8:53 pm

    Forgive me but at times I struggle with what words to use but here goes.

    I have several mov videos that are 1080p with the alpha channel set to yes

    I want to resize them to 720p and still keep the alpha channel set to yes

    I installed FFmpeg and have been searching for days on how to do it but so far no luck.

    Can any explain how to do. Please explain as if I’m a complete newbie. A lot of the things I do find when searching the net goes right over my head.

    thanks

    [steve wilson] ”

    I’m not sure what you’re referring to here. What says it is set to “yes”, and what is that supposed to mean?

    Please show the complete console output of:
    ffmpeg -i input
