DVD2DVD-R Frame Drop

[wanderance]

Not sure if this should go in the CCE forum or DVD2SVCD. Currently to take a DVD-9 down to a DVD-R I use DVD2SVCD with some tweaking. It currently works great, and I am using the default CCE setting with DVD2SVCD. Recently I am taking my X-FILES season DVD's and backing them up. I noticed in certain parts of the episode there appears to be a stutter or frame rate drop, like it is going down to 15 or so FPS. There is no loss of syncs and seems to happen only when there are fast moving object. For example a car speeding down the road, or at the end of each epside the Fox logo with the spotlights.

Is there something I am doing wrong? Or should I take this up with the CCE Forum?

Thanks!

Ok have you checked to see if your dvd player is compatible maybe try lowering your bitrate .

All problems when using dvd2svcd that your having belong in the basic forum.

It occurs regardless of player. The resulting MPEG file that CCE creates has the "stutter" if that is what you want to call it.

If you are encoding with the setting of 16:9 no border encode as 16:9 to create an anamorphic SVCD, many players have issues with this setting. See the Q + A for more info.

Use either 4:3 encode as 4:3 for a no border for widescreen TV or use 16:9 add border encode as 4:3 instead.

Hi there,

I wonder if this is caused by the wrong "Field order" setting for CCE. From my experience and from some others that did some investigation on this CCE behaviour the best setting is "Bottom Field first (field B)" to prevent CCE to mess things up.

Here's a good explanation by stanwebber (I don't link his homepage as it also contains some adult material and porn popups):

Contrary to the obvious, the upper field first checkbox has nothing to do with setting the TFF (top field first) flag. In fact, Cinemacraft encodes with the TFF flag ON regardless of any setting. Enabling upper field first in reality inverts the field order by shifting the entire image up 1 pixel....even scanlines become odd and vice-versa

CCE v2.5 field dominance switch bug

orig           upper    post            TFF          end
field          field    field           flag         result
order          first    order
-------------------------------------------------------------
top-first      on       bottom-first    top-first    mismatch 
top-first      off      top-first       top-first    correct 
bottom-first   on       top-first       top-first    reverse 
bottom-first   off      bottom-first    top-first    mismatch

This causes order reversal or mismatch problems if your source is anything other than top-first as indicated on the chart. The solution is to pre-empt Cinemacraft from altering anything (upper field first OFF) and set the TFF flag with Pulldown at a later stage. Progressive material (IVTC/forced film or PAL standard telecine) is unaffected other than being shifted 1 pixel and thwarting attempts to letterbox on 16x16 macroblock boundaries

So you should try to encode a chapter where the problem is visible with the "Bottom field first" setting and see if this helps with this issue.

At least for PAL I haven't found a movie yet that causes problems by using this setting as default - this applies to true interlaced PAL DVD sources, DV AVI sources and the biggest portion, the progressive material I've done so far - so I now use this as my default setting.

HTH,
Gerti

P.S. There's a little bug in the latest DVD2SVCD - it does not save the settings of the "Field order" pulldown and always reverts to "Automatic" on a re-start. But you can edit the "dvd2svcd.ini" and add this parameter "CCE Field Order=1" under the "[Settings]" section to cure this. (0=Top field first, 1=Bottom field first, 2=Automatic)

Well, I tried all the suggestions and the behavior still exists. I have seen some other posts about people encoding the x-files dvd's, I wonder how they did it, and if they had the same problem.
