How to use avconv filters after encoding?

Question

I have this avconv command:

avconv -i file -s [new size options] -vf "[filters]" /root/converted/1.mp4

Avconv uses the -vf filters before the -s scaling, but I need one avconv command to:

1. Resize video first
2. Use filters second

How can I do it?

Answer 1

Create a chain of filters, where you add a scale filter in the first part of the filter. E.g.:

avconv -i file -vf "scale=w=1920h=1080, [filter B], [filter C]" /root/converted/1.mp4
