FFmpeg multiple video filters chaining

[pascor]

Environment: Windows 8.1, ffmpeg v4.4 on command line

By trial and error I've found that two video scaling filters can be chained/serialized, in this case the unsharp filter:
SET Unsharp=luma_msize_x=5:luma_msize_y=5:luma_amount= 2.0

... -vf scale=1920:-2:flags=lanczos,unsharp=%Unsharp% -vf scale=-1:-1:flags=lanczos,unsharp=%Unsharp%,eq=brightness=-0.05aturation=1.05 ...

In the second filter 'scale=-1:-1' does prevent rescale processing from happening.
Adding a third '-vf scale=-1:-1:f ...' filter to separate out the brightness/saturation filter causes the first two scale filters to be completely ignored.

1- Can multiple video filters be combined into a single -vf statement ?
2- Can any kinds of video filters be combined ?

The complete CMD script has been attached - remove the '.TXT' extension to use.

You can't chain multiple -vf. You have to chain the individual filters in one -vf.

won't work: -vf filter -vf nextfilter -vf anotherfilter -- (only the last -vf will be applied)

will work: -vf filter,nextfilter,anotherfilter

That's the ticket. Thanks !

SET Unsharp=luma_msize_x=5:luma_msize_y=5:luma_amount= 2.0
-vf scale=1920:-2:flags=lanczos,unsharp=%Unsharp%,unsharp=%Unsharp %,eq=brightness=-0.05:saturation=1.05

(A "Befuddled" emoticon is automatically substituted for the 'colon,lowercase-s' immediately after '-0.05'.)

When you're editing a post there's a option below the edit box: Disable Smilies In Text. You might have to press the Go Advanced button to get it.

-vf scale=1920:-2:flags=lanczos,unsharp=%Unsharp%,unsharp=%Unsharp %,eq=brightness=-0.05:Saturation=1.05

as a side note: either put your "-vf"-call options inside quotes (") or make sure you don't have white spaces in them,... otherwise you will probably run into issues,..
