> Hey,
I’m using VCS via Homebrew Install (https://formulae.brew.sh/formula/vcs#default) and since the last update of imagemagick (?) I get dozens of error messages:

>convert: Expected operator at ‘.mean*100’ @ error/fx.c/GetOperator/2408

Confirmed to happen on ImageMagick 7.1 on Linux, the contact sheet is generated but blank frame evasion is skipped

FS#377: Allow screenshotting half of the video (for side-by-side VR videos) Toni Corvera Wed, 03 Feb 2021 17:11:00 +0000 Asked by Bob on the blog

Would it be possible to somehow specify to only screenshot half of the video image (for 180 side-by-side VR videos)?

Or would this require new features to be added to the VCS?

Hi I am trying to thumbnail some HDR content is there anyway to insert ffmpeg filters in
-vf zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=mobius:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p

Thanks

I’m also trying to do some HDR content and pass the -vf info to ffmpeg. I can’t get it to work even using a wrapper script.

It always comes up with awk errors, starting with “unterminated regexp”.

Is there any chance of updating vcs to support manual passing of those -vf arguments to ffmpeg?

HDR content is very common nowadays…

I’m using vcs 1.13.2 on ubuntu and ended up doing it by adding the line:

-vf ‘zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p’ \

at line 2203, in the ffmpeg_capture() function where it sets the ffmpeg command line options.

Couldn’t work out how to do it with a wrapper script.

Run vcs on sample#.avi -> sample#.avi.png is created.
Run vcs again. sample#.avi-1.png should be created, but sed generates an error.
