Problem with deinterlacing a video in Avisynth

[elektro]

I'm trying to deinterlace a video (see the sample) but it seems it was weirdly interlaced in the first place because it produces ghosting. Does anyone know how to get the best progressive output with the least ghosting as possible? Maybe it's a separatefields() trick?

Could you clarify a few details:

1. Can you share the current FFmpeg command you're using for deinterlacing?
2. Are you seeing horizontal or vertical ghosting?

for deinterlacing with minimal ghosting, FFmpeg offers several methods:

Deinterlacing Techniques
| Method | FFmpeg Filter | Best Used For | Ghosting Potential |
|--------|---------------|---------------|-------------------|
| Yadif (Yet Another Deinterlacer) | yadif | Most common scenarios | Low |
| Bwdif (Bob Weaver Deinterlacer) | bwdif | Higher quality, more processing | Very Low |
| Blend Deinterlacing | blend | Slow motion content | Moderate |

ffmpeg -i input.video -vf yadif=mode=send_field:parity=auto -c:a copy output.mp4

The key parameters I recommend experimenting with are:
- `mode`:
- `send_field`: Sends both fields
- `send_frame`: Sends one frame
- `parity`:
- `auto`: Automatically detects field order
- `tff`: Top field first
- `bff`: Bottom field first

he does not need to experiment with type of deinterlacers (again or read some google general something), he needs to fix his video, possibly re-arrange fields to progressive frames, if it is still possible, using avisynth (as he actually suggests),

You can try qtgmc with srestore, for example

lwlibavvideosource("c:\users\davex\downloads\sample.mkv")
qtgmc(preset="medium")
srestore()

Thanks.
