I have a DV video that I want to have more cinematic look. I usually do that with deinterlacing and some color corrections- But now I have video that can't be deinterlaced fine. It is PAL DV with bottom field first and has lots of panning and handheld shots with horizontal text scrolling. I think I tried every deinterlace plugin I could find for PC and Mac - different smart, motion adaptive, area-type, mumbo-jumbo etc. deinterlacers for AviSynth, VirtualDub, Premiere, After Effects... I tried standalone deinterlacers too and even tons of plugins and tools for Final Cut Pro and even some tricks like blending multiple different deinterlaced videos in several tracks, separate fileds and manipulate them with joining again and frameserving to VirtualDub etc.

No luck.

Whatever I do, I get crappy stuttering pans and completelly unreadable scrolling text.
I'm experimentig for over a week with this and I stumble to somethig interrested - AviSynth blur function (vertical bluring only), VirtualDub fieldBob (1/4 up or down for both fields) and Flicker Filter in Final Cut Pro (set to minimal), produce cinematic look and motion without deinterlacing! Video is still interlaced and has film look! I tested it on TV (tested on CRT, LCD TV, Plasma TV and LCD projector) and picture looks prety much like film (or HD video which is also fine for me) with "film-like" fluid moving shots and not flat "video-looking".

I assume that this is caused by adding little ghosting/shadows to the edges of fields because that's only common thing for these three filters (as I see when I separate fileds and inspect them). And that is also a problem with these filters - they give cinematic look and motion and leave interlaced video (although that is not their primary functionality but more like sideeffect) but shadowing/ghosting (that obviously produce cinema-look) are a bit visible during some pans and scrolling text. And moreover, some parts of video are not affected with these filters and stays in "video-look" (even moving parts with lots of interlacing!)

All this problems are not very annoying (much less annoying than stuttering after deinterlacing) but what's bother me is fact that I have several DVDs with DV documentaries shot on cheap interlaced DV cameras like mine - but they post-processed video somehow so on DVD it looks like film and have film-like motion and it is smooth in panning and other shots without any artefacts. And are interlaced. So, any ideas how to reduce that ghosting or have some other ideas how to get cinematic look and motion without deinterlacing?

Or even better, how to deinterlace PAL video with pans and horizontal text without jerky and stuttery results?

This is obviously possible but I can't figure out how
I am out of ideas
