Antwort von Stefan:

Avisynth can do that

However, I no automatic fault finder known and I am afraid you have a lot of work to find the missing fields.

But so far I am not familiar with Avisynth not synonymous. A very good forum to Avisynth is forum.gleitz.info.

Good luck

Hello Stefan,

Thanks for the quick reply. By avisynth I had read, and once it downloaded into the folder video tools ;-)

Hm .. I must now, through well. Is there a avisynth Instructions for the impatient? If only I knew where to find time for: - (

I will then report on my failure / success. Ah, yes: The phenomenon occurs once or twice per movie, so the effort is just about acceptable, if it's going to be easy to solve with avisynth. The sound makes me to still make something ...

Hello,

So yes avisynth is properly care for. Something Crafts Optical brings the wanted result: No longer in the stepped-stairs effect moved files:

clip = DirectShow source ( "test.avi")
fclip = SeparateFields (clip)
even = SelectEven (fclip)
odd = SelectOdd (fclip)
Weave (Interleave (odd, DeleteFrame (even, 0)))

Now I have two new problems:
There is a lack of direct processing of the codec for "fourcc dvsd" well above command only brings the picture with.
How do I get the avi to Scenalyzer? Windows Movie Maker reads the clip of one avisynth not correct, then breaks off easily. Also a different video editing software could not import the avs.
Let's see if I make a "cheap" video editing software for testing can muster.

I was certainly surprised with how fast was a bit trying the avisynth script ready.

Antwort von Stefan:

Ah yes, the infinite wisdom of the good Bill. Give its Windows only enes DirectShow DV codec with ...

You can instead try to put a VFW compatible DV codec installed in addition to as the Panasonic DV codec and (!) On firewire transfer as previously type-1 AVI Type-2 AVI save. For good transfer programs, you can select the ... (WinDV, CaptureFlux, ScenalyzerLive)

You may save the Avisynth output as AVI, I'm always with VirtualDub. Virtualdub can cut synonymous and include recently (1.6.12) synonymous DV over DirectShow. Saved as AVI Type-2.

Good luck

Hello Stefan,

Thanks for the tips.

Yesterday was completely displaced in VOX, a film, so easy.

Panasonic codec installed, AVISynth script OK, output works fine in Media Player, sound seems to be synonymous synchronously. Virtual Dub installed, but now I've finally arrived s.Anfang my stupidity to march out of it this way around ...

I can open the video in Virtual Dub and play. If I save as AVI, the file is extremely large, and the video jerky. How do I get the video changed or saved as DV-AVI?

Antwort von hjreggel:

Hello,

Looks like I would have had two fallacies. Thus, I surmise times:

The output of AVISynth DV-AVI is no more, but any other format. Thus, "Direct Stream" not good, but I have to use the Panasonic codec.

The thing with the half frame Verschieberei not possible without re-coding, because the surgery even Frame Cross work.

How is it such a lossy re-coding of DV-AVI?

Let's see if I accidentally s.Wochenende, durchzunudeln complete the film. In any case, I'll keep you up to date ...
