Again unexpected jumping frames

[dplaton]

On a RAW YUY capture AviSynth-> MPEG2 I have some jumping frames.
Looking at the source in 2 ways I found 2 different things.

AviSynth separatefields shows messed fields a much earlier field is inserted between 2 current field.

VitrualDubMPEG2 viewfields() shows a duplicate frame.

What is the true?


Can I use dup220b1 to identify the duplicate frames, there are very few 3-5 at a 5 minutes clip, but they are very dusturbing.

I encode interlaced.
The field order is TFF.

could you provide an unprocessed sample of this video?

I am a little bit irritated by you explantation.

maybe deshaker could help out. (brute force method)

Now I don't have one, I'm at office and my clip are home.
The material is huge 1.2 Gb per minute.

Encoded directly with TMPEG VirtualDub-MPEG2 shows 2 identical frames.

Also I experienced some green frames.
I found that the frame order is set oposite AVISynth generate
this green frames or frames with green splashes/spots

I think it's an AVISynth bug.
To solve the problem I
1. open with VirtualDub-MPEG2
2. frameserve to test.vdr
3. AVISynth script with source test.vdr and dup() maxframes=1
4. start DebugView
5. load avs to a player
6. save the debug log
7. sort by difference the debug log.
8. identify the duplicate frames.
9. search the avi to see if is a static or a changing sequence
10. encode the avi without the duplicate movement frames.
