Yes, I indeed converted with ConvertToYV12(). It was AssumeTFF().ConverttoYV12(). Does the AssumeTFF() argument change anything? If not, then you found the reason for ghosts playing drums:-) Thank you for finding and for explaining that to me. I learn things here that I never would have thought I'd need to deal with... Really appreciated!

I converted to ConverttoYV12 because I had Despot in my script. I just read on Despot's description that it also supports "special planar YUY2" format (is that YV16 then?), so maybe I can change that to stay in 4:2:2. Which I'd prefer either way. Also, that script is not final yet, so requirements from plugins may change. I'll keep an eye out for proper conversions.

Thank you again Emulgator & Sharc for this excursion.

Back to my task to find a good way for chroma shift, but maybe I'll wait for my CUDA-compatible GPU first...

Your Sample3_unaltered.avi is interlaced, Bottom Field First, hence AssumeBFF() would be correct, regardless what MediaInfo may tell you.
If you want or need to convert to 4:2:0, use ConvertToYV12(interlaced=true)
If you want/need 4:2:2 planar use ConvertToYV16(interlaced=true) instead.

(In any case you should always know whether your video is interlaced or progressive before applying a certain filter, and use the filters accordingly. Take note that many filters work on progressive video only and are not interlace aware. Filtering of interlaced video is a topic of its own).

from 4:2:2 interleaved (YUY2) to 4:2:2 planar (YV16) the parameter interlaced=true is not needed

from http://www.avisynth.nl/index.php/Convert:
Note, interlaced=true has an effect only on YV12↔YUY2 or YV12↔RGB conversions. More about that can be found here.

Yep, thanks. I left it routinely in as it does no harm either
