View Full Version : Pure NTSC interlaced content gives weird playback..

I've encoded a region3 DVD (Dark Water) ,
DVD2AVI gave me a pure NTSC interlaced reading,
CCE did a great job,
Maestro gave NTSC Drop reading,
I tried to insert chapters and got an error message , did that manually and compiled dvd, my set top box (Pioneer 454) gave me jerky playback ( on fast scenes you can notice that one second old frames would play as action would progress ).

I tried pulldown with the drop frame flag - false and nopulldown, Maestro gave NTSC reading without the Drop and the chapters were inserted without error message, dvd plays fine in PowerDVD but my set top box still gives me the same jerky playback.

I've run out of ideas, should I use pulldown with some other parameters ?
Should I give you guys any more details

Sounds like the interlaced source may need the fields reversed on playback, and you may be suffering from CCE's less-than-ideal treatment of interlaced fields.

1st, make sure you don't have 'Force Film' turned on in DVD2AVI.

Then, when encoding in CCE, follow these rules: (posted elsewhere in the forum, thanks to Tsui for this info):

for tff-source :
deactivate 'upper field first'
deactivate 'progressive frames'
deactivate 'zigzag scanning order'

for bff-source :
deactivate 'upper field first'
deactivate 'progressive frames'
deactivate 'zigzag scanning order'
correct the field-order flag with darims easy changer or pulldown.exe or restream

for progressive-source :
deactivate 'upper field first'
activate 'progressive frames'
activate 'zigzag scanning order'

To run pulldown on the resulting stream for the BFF option, use:

pulldown <source> <target> -nopulldown -norff -tff even
If that doesn't eliminate the jerky playback either, switch to TMPGenc for encoding rather than CCE, it handles interlaced video without this workaround.

I'm also having that problem.
I'm trying to backup a dvd from a concert by Yanni (region 1) and:
-DVD2AVI reports as 100% NTSC (sometimes, during the preview it says 99% NTSC), so i left the forced film option unchecked.
-I tried cce with the values i got from bitrate viewer
-I imported the resulting m2v file on Maestro, and i also couldn't import the chapter list, so i made it manually.

After burning to DVD+RW, i saw it in my standalone player (pioneer DV-444) and the picture is jerky everytime there is a horizontal movement.
I also tried TMPGenc, but i must be doing something wrong, because i can't get rid of this problem.

Any suggestions ?

I'm used to PAL movies...
