Is Superview just stretching to 16:9?

[RustyToad]

Hi, I've had a quick look at the source and unless I'm missing something, the "superview" function is just stretching the input file to 16:9

function superview() {
    for i in *.MP4;
        do name=`echo $i | cut -d'.' -f1`+S;
        echo $name;
        ffmpeg -i $i -q:a 1 -q:v 1 0 -vcodec mpeg4 -acodec ac3 -aspect 16:9 -strict experimental $name.MP4
    done
}

Isn't this missing the clever dynamic stretching that superview actually does, where the centre is unstretched and the edges are over-stretched to compensate?

I've been searching for a way to do this in Ubuntu, but not found anything yet.

Yes it is missing that.

Thanks for the reply. Have you ever found a way to do this (create a genuine superview-like stretch) on Linux?

[KonradIT]

No, it can be done in Premiere.

too bad - was about to check the issues for the same thing. Thanks for clarifying

Not possible in kdenlive?

[RustyToad]

Not possible in kdenlive as far as I have found, no.

@RustyToad you could use this: https://github.com/Niek/superview, the "algorithm" is fairly basic, but it's at least better than normal stretching

@alexagv I've only just seen this (gmail filters things a bit oddly these days), thanks for the link. I'll download and check out that project this afternoon.

I've actually bought a gopro Hero 5 session since starting this thread, but would still like the option of generating this style of footage with other action cams.
