jittery video...Help?!

[aussiemac]

I have captured from Digital 8 camera thru firewire via WinDV to HD.

Then I used GSpot to check captured file details...

720 x 576 PAL DV

Then loaded avi into FitCD to get Avysnth script for CCE 267
Here is the script:

****************

# -= AviSynth v2.5.6.0 script by FitCD v1.2.8 =-
AVISource("J:\capture\schubert\schubert.00-11-27_14-40.00.avi",pixel_type="YUY2")
SeparateFields()
LanczosResize(688,208,0,35,720,218).Weave()
AddBorders(16,80,16,80)
Trim(100,1000).FadeOut(150)
ConvertToYUY2(interlaced=true) # For VirtualDub or CCE

********************

Then dropped this into CCE 267

only change to CCE settings was to change from 'ZigZgag' to 'alternate'
and deselect 'progressive'

and change flat area priority to 28

Played out put with PowerDVD ...getting jittery video
short jitters ...not jerks
its not interlacing lines...ie jaggies.... but slight jittering

I changed output file to mpg
and burnt to DVD...for testing on TV

Still same on TV

Is this "weave" setting in the Avisynth script causing this jttery output
or is there another field issue I havent noticed...????

Appreciate any help
+++++++++++++++++++++++++++=
Edit:----I had the source as YUY2...in FITCD

# -= AviSynth v2.5.6.0 script by FitCD v1.2.8 =-
AVISource("J:\capture\schubert\schubert.00-11-27_14-40.00.avi",pixel_type="YUY2")


removed that...and redid encode

output in Powerdvd still looks jittery

Any thoughts or suggestions???

Probably wrong field order. Use restream to reverse the field order on the output from CCE. Play the output from restream.

Thanks for tip Abond...

I am only doing short test encodes at moment...1000frames

So how do I change field order ...is it in avisynth script part

or in CCE 267 settings???

Thanks

[aussiemac]

I went back and looked at FitCD settings

it has a bff->tff setting ...or tick box

I ticked it and output another avisynth script...for CCE

did short encode with CCE...

played mpg with PowerDVD

...DAHDAH!

It looks like it fixed the jittery video

Its been a while since I have played with DV



Thanks...Abond...for future reference!

[Abond]

To save the time you can use restream directly loading in it the mpv output from CCE. On the left middle part you will see that top field first is marked. Unmark it and click write. It will write new file name.0.mpv. Play it to see if the problem disappear.
For avisynth
....
AssumeBFF()
Separatefields()
.....
But you must take in mind that CCE encodes always top field first. If you want to reverse the field order (I think) there is something like Offset line setting in CCE. This will delete the top scanline of the video making the bottom field to be top field and CCE will encode top field first (TFF).
If you want to preserve everything use HC encoder.

Thanks...Abond

I hadnt done the whole DV file ...just doing test short ones as mentioned

...Thanks for the avisynth code change ...
will use that in future scripts
I have another 6 DV tapes to do

I noticed that field in CCE....thought it may have some relevance
but am always nervous changing settings in CCE

that it is also going into the memory bank..if any other problems
like this occur...

Do you use prefer HC encoder ??
or is this just a suggestion to fix the CCE top field problem?

[Abond]

Well, I wouldn't say this is a problem with CCE, simply this is how the encoder works. Usually I preffer HC for low bitrate encodings at best mode. Though I really don't know how it performs with interlaced material.
I am making relatively rare DV conversions. There was something strange with avisynth field orders and CCE, but I could not remind what it was exactly. Anyway, try samples with different settings to check it. Well, good luck.

yep..restream saves me a ton of time when i goof up and accidentally encode in the wrong field order. Takes care of the mix-up real quick!

Under Advanced change Offset Line from 1 to 0
