DVD2SVCD Aspect Issue / Pulldown Problem

[Apaullo]

Hi all, first time here.....

I have an interesting problem. I tried to rip 2 vobs - one a film trailer (4:3), the other a small video interview (16:9 anamorphic), just for testing purposes. They were ripped with Smartripper. The film trailer is obviously 24 FPS, and the video interview is 29.97 FPS standard video.

I first wanted to see if DVD2SVCD (v1.0.7b4) could properly create the correct aspect in 1 mpg for both sources. It couldn't; the first experiment I tried 4:3 in the Conversion setting, the video interview was squeezed in from the sides, but the trailer was fine. In the second experiment, I tried the 16:9 setting - the video interview was fine, but the trailer was squeezed in from the top and bottom. Does that make sense... CAN DVD2SVCD make a single, all-correct mpg/disc image from sources with different aspect ratios?

Now for the main problem I've been having all day. There was something else strange to the look of these experiments, they were kind of "jittery". especially on my Apex AD-660 standalone. The trailer contained lots of action sequences and the high movement scenes seemed to "bounce" all over the place (low-movement scenes looked fine). I tried DVD2SVCD again, just on the film trailer vob, and this time i noticed, during the process, it invoked "Pulldown". I burnt the CDRW and it played back PERFECTLY. So I tried DVD2SVCD on the video interview vob, but during its process it would NOT invoke Pulldown.

Why? Is pulldown not supposed to happen on 29.97 FPS sources? I'm convinced that is how to take away the "jitters". The best results I got all day was selecting "Smart De-Interlace", but that still wasn't perfect (I have yet to try to mess with Smart DeInterlace options). I thought, by looking right at the program, the Pulldown was ONLY NOT invoked on PAL sources.

One more thing: "ForceFilm" in the DVD2AVI tab was set to OFF for the video interview, and ON for the trailer. When I did them first at the same time, I set it to OFF because I know standard video footage looks awful when forced down to 24 FPS.

Thanks in advance for any help. :)

most of your Q's can be answered by reading the guide and faq. therefore i don't think this is an advanced subject. nevertheless, here's some info:
force film should be used in 24fps material. this way the output file is also 24fps. because your tv expects a 30fps signal (in ntsc), pulldown is used to make up for this difference.
if the input material is 30fps, force should not be used. pulldown is not necessary.
for most purposes, just leave the forcefilm at "automatic". it will be just fine in almost all cases.
regarding jerkiness:
--concert, music, documentaries (uncheck CCE Upper Field first to elminate jerkiness) -mrbass
regarding aspect ratio:
different people have different needs. "all-correct" is not what everybody is looking for. there is a sticky at the basic forum about this subject that is very enlightning.

Cheers :)
