Jeryky SVCD playback after DVD2SVCD conversion

[noaht1980]

1st of here is the process i went through

___PREPARING FILES____
1.Rip the files off the dvd
2.Created the d2v video file
3.Created the m2v audio file
4.Converted audio to Wav file

___CONVERTING TO SVCD____
1.Started Up TMPGEnc
2.Loaded Up Video = dv2 file
3.Loaded Up Audio = wav file
4.Loaded up NTSC CQ Template (From DVDHelp.us site)
5.Converted the file to MPEG

Here is the settings i used in the advanced settings in TMPGEnc

Video Source Type = Non interlace (Progressive) (I ALSO TRIED INTERLACE)
Field Order = Top field first = (field A)
Source Aspect Ration = 4:3 525 line (NTSC)
Video Arrange method = Full Screen (Keep aspect ratio)
I also used CQ 100

Here is the info about the dvd i get from Bitrate Viewer

Num. of picture read: 31
Stream type: MPEG-2 MP@ML CBR
Resolution: 720*480
Aspect ratio: 4:3 Generic
Framerate: 29.97
Nom. bitrate: 9000000 Bit/Sec
VBV buffer size: 112
Constrained param. flag: No
Chroma format: 4:2:0
DCT precision: 10
Pic. structure: Frame
Field topfirst: Yes
DCT type: Field
Quantscale: Nonlinear
Scan type: ZigZag
Frame type: Interlaced
Notes:

Ok now on to my problem lol

when i play this file on PC and also on Standalone
i get jittery playback when there is movement in the movie (ITS NOT PIXELATED) its actually jittery instead of people walking/running smoothly
its stutters its something i have never had a problem with before

Its getting really frusterating lol 3 days in a row i have tried figuring this out luckily only 2 coasters (bought CD-RW Disks)

1) reverse field order

2) don't use CQ above 75. when you use CQ = 100, it's basically the same as if you used CBR at your max bitrate. basically, every scene will have the same bitrate as the max bitrate you set. that defeats the purpose of VBR. you need to let the encoder vary the bitrate between the scenes, so that less bitrate is given to slow action scenes and transferred over to fast action scenes.

So you think if i do the following i wont get that jerkey playback

1.Change from Top Field First (field A) to Bottom Field First (field B)
2.Change from CQ 100 to CQ 75

You think will stop this jerky playback

Also why would i have to change from Top Field First (field A) to Bottom Field First (field B) ?

Sorry but im new to this and i have never had to change that so i was just curious on the reason behind that

Thanx for your help all the time hopefully pretty soon i will have this all figured out lol

1) the CQ is just for efficieny purposes...it has nothing to do with jittery playback.... personal experience and others have suggested that CQ above 75 would be waste of filesize will little improvement in quality...basically, the increase in filesize is not worth the little improvement in quality

2) field order can sometimes cause this...just a guess....

oops, you know what...i just read your choices in tmpgenc..there's a problem......however, i need more info from you first.

when you create the .d2v project file in dvd2avi, an info box should appear to the right. it will mention the video type as FILM (or some percentage of FILM) or NTSC (or some percentage of NTSC)....

can you give me those numbers??? be sure to watch it completely through the movie, as it may change throughout the movie...

--------

if the movie is basically 90+% FILM, then you should turn ON forced film in dvd2avi and in tmpgenc, your output video should be 23.976 fps + 3:2 pulldown (NOT INTERLACED).... in advanced settings, video source type should be non-interlaced, progressive. field order shouldn't really matter in this case because the output is NON-interlaced.

otherwise, you need to turn OFF forced film in dvd2avi and in tmpgenc, your output video should be 29.97 fps + interlaced (NOT 3:2 PULLDOWN). in advanced settings, video source type should be interlaced. field order will make a big difference in this case because the output is INTERLACED....

Here is a screenshot of what shows up on the right side of the screen and i watched it through and it stayed the same

so what should i do now?

Thanx for everything

Use Eazy VCD from the tools menu, nice and simple.

[poopyhead]

VIDEO type is NTSC...

so in dvd2avi, you need to turn forced film OFF.

in tmpgenc, the OUTPUT VIDEO needs to be 29.97 fps + interlaced (NO 3:2 PULLDOWN)

in advanced, source video type needs to be interlaced

as for field order...this gets tricky...you may need to do a little test on cd-rw....field order will definitely matter...if you choose the wrong one, the video will be very, very jumpy... i am not sure which one is the case...as sometimes it is different from movie to movie..even i still test on CD-RW for cases like these...

keep in mind, the jumpiness will only show up on TV, NOT on computer monitor..so you need to test the short clip on CD-RW on TV, not on comp.

also, keep in mind that since the output is interlaced, you will have hard time watching this on your computer. the reason is that a computer monitor is progressive. meaning it's designed to play progressive video (i.e. non-interlaced). by making your output video interlaced, it will NOT look good on the computer. however, your TV IS designed to play interlaced video, so it will still look good on your TV.

ok thanx i will try a sample here in a minute and see what happens

[noaht1980]

ok im about to do a sample here are settngs i have

Super Video-CD NTSC (MPEG-2 480x480 29.97fps CQ 75, Layer-2 44100Hz 224kbps)?

Does that seem fine?

also

Video Source Type = Interlaced
Field Order = Top field first = (field A)
Source Aspect Ration = 4:3 525 line (NTSC)
Video Arrange method = Full Screen (Keep aspect ratio)
CQ = 75


and if this doesnt work i will try
Field Order = Bottom field first = (field B)

[noaht1980]

Well i just ran a 10MB sample = 36 secs and i didnt see the jitterness anymore but i will encode the whole thing right now while i goto bed and report back tomorrow

Thnx

[noaht1980]

Thanx for everything poopyhead

I just burned the whole thing on a CD-RW and that jerkyness is gone

Sweet i aprpeciate all your help

[poopyhead]

np...

--------

but if dvd2avi's info box tells you the DVD source video is FILM, you should turn ON forced film in dvd2avi and encode in tmpgenc as 23.976 fps + 3:2 pulldown (NOT INTERLACED)

i.e. Super Video-CD NTSC FILM (MPEG-2 480x480 23.976fps CQ 75, Layer-2 44100Hz 224kbps)

of course, video source will be non-interlaced, progressive

------

you should do this way if you can...because this will improve the video quality, as there are less frames per second to encode, so each frame gets more bitrate...but ONLY IF source video is FILM.
