Yes, you're right. But I think the real problem is in the way avisynth processes the frames. Ideally, avisynth should first deinterlace the entire video before proceeding to the next step (the firstpass Deshaker part). And then it should do a full first pass and after that the full second pass. But I think avisynth kind of works on a frame-by-frame basis, so it does not deinterlace the entire video before the the firstpass Deshaker part is called. And that's the real problem I think. And about the skipping of the firstpass: I think that the avisynth interpreter first looks to the entire script, and then sees that in the output (eval statement) only "secondpass" is present. So it thinks that firstpass is not explicitly needed and therefore skips that part. In other words, avisynth does not run the script line after line. Could someone confirm this behavior of avisynth? Or is there still another way to accomplish my goals?
