Thank you, s_option is very powerful as I can see!

I will play with it in this "24-to-25 audio" case and with another case where we try to deal with "normalization to FullHD" of unpredictable Apple Dolby vision 4k using nvenc (to free procs).

Hehe great that you found something useful :D
Not to mention that the internally generated ffmpeg command can potentially change not only with every source file type/flavour but also with every update. So if you use this, you'll have to ensure that it still works as expected before you update your ffastrans installation.

Some things are more upgrade safe of course, e.g. inserting "pre input" parameters might work forever becauese "-i" was always there, while working in filter strings is considered to be highly unstable because filtering can change not only depending on source file but also because we just have to or want to change it internally.
emcodem, wrapping since 2009 you got the rhyme?
