SVCD is choppy

[Boomer8]

I followed this guide= https://www.videohelp.com/forum/userguides/166237.php found on this site to convert a pal svcd to an ntsc svcd, I followed the guide to the letter. One thing I don't understand but has been partially answered is in tmpgenc just before the encode process (the setting up part) when you select svcd film which is 23fps tmpgenc displays the frame is actually 29fps I've been told that its just a misprint in the program. So I just ignored it and encoded it anyway after that was finished I mulitplexed the files together viewed it with windows media player and noticed the audio was out of sync but it actually wasn't after alot of hair pulling I read that windows media player puts the audio out of sync in some cases so I opened it up with powerdvd and sure enough everything was fine. So then I opened up nero Burning Rom and burnt the file to a cd-r I put it in my svcd compatible, centrios standalone dvd recorder and the video was choppy as if somehow the video was actually encoded into a 29fps video anyway, I did this entire method twice to the letter because the svcd has two parts, disc one and disc 2 both turned out the same I even checked the files with gspot and avi info both tell me the FPS is 29, but it is supposed to be actually 23FPS does nero somehow convert it back to 29? Also when I play the video in my pc using powerdvd there is no choppyness it plays perfectly alright.

I do think that in SVCD NTSC or NTSC Film, TMPGenc convert them always in 29fps. Only in VCD NTSC film it converts them in 23.976fps. I have many SVCD movies and all of them are in 29fps regardless of NTSC Film or Just NTSC. I do have a PAL SVCD and I am not sure what to do with it because my dvd player won't play pal SVCD. SOrry I couldn't help you

I do have a PAL SVCD and I am not sure what to do with it because my dvd player won't play pal SVCD.

the link I posted that refers to a guide will help you out alot. Alot of people have had succes with that mthod including me except for this one somwhat minor flaw. which I really need help with.

One other thing in gspot it says the FPS is
29.970 (59.939 fd/s, 23.976 p/s)
can anyone tell me what the 59.939 fd/s, 23.976 p/s
in brackets mean? those numbers are in the same box with the FPS.

I just checked the FPS with virtual dub mod (file, file information) and the fps is 23 and the bitrate 1500kbps. Hopefully this is enough information for someone to help me.

29.970 is the framerate of the file at which it will be played. (29.970 frames per second)
59.939 fd/s means fields per second. Every frame has two fields - TV display fields.
23.976 p/s pictures per second I think - the original framerate of the video.
This is possible due to 3:2 pulldown during playback setting in TMPG. It set pulldown flag in the headers which tell to player to repeat fields from adjacent frames in order to achieve 59.939 fd/s from 23.976 p/s..
VDub recognizes correctly the original framerate.
And the last - better use VCDEasy to make CD image (cue/bin) and burn the image with nero.

To be blunt, no one who is serious about PAL->NTSC conversions uses TMPGenc to do it. I'm sorry, but that is the truth. The same goes for NTSC->PAL conversions. I have read in other forums that people have had great success doing 2 things - 1) Using Canopus Procoder to convert. Procoder is REALLY expensive though. 2) Using AVISynth scripts to convert. A web search should locate some scripts on how to do this. The forums at http://www.doom9.net may have some info on this kind of conversion using AVISynth.

Is it a choppiness in the video or more of a flicker? This could be caused by the Field Order option (is this correct? I can't remember the labels) You need to make sure that it places "B" frames first instead of "A". Damn, I really wish I could remember what I was talking about. Only been about 3 years since my last SVCD so go figure.

Bottem field first (field b) was selected when I encoded the file but in the one image of the tutorial it shows top filed first (field A) as the selected one. So I'll tru that and lowerthe bitrate, VCDeasy says it won't fit on a 74min cd-r and suggests I use a 80 min cd-r which I have anyway but in nero it won't allow me to burn it because the actual file size is about 80mb too big.

I just tried something else because I didn't have too good of a feeling about this whole svcd thing and I really didn't want an svcd anyway because it would not play on the dvd player I wanted it to (doesn't support svcd only vcd).So I would have had to move the one I have in my rec room to the living room just to everytime I wanted to watch a svcd movie. So I combines two tutoirals together and result was perfect (not qaulity wise, not the greatest but O.K.) What I did was I used THIS guide first, to get my svcd .mpg (every step of it), the mulitplexing part possibly could be left out because when I use dvd lab (other guide) it suggests you de-mulitplex the file anyway and it might do a good job keeping things in sync even if you load the files seperatly (have not tried this) then I just used THIS guide to make dvd compliant folder in dvd lab and then I burnt the video to a dvd with CopyToDvd. Worked like a charm. Also I could have fit 4-5 other movies on there if they were svcd's but the quality would have obviously not have been as good as an actual dvd. One thing I didn't quit understand was why did it work on my dvd player that doesn't support svcd? the resolution was still 400x400. only SVCDs come in that resolution. Unless it's an audio issue instead with my dvd player becase dvd-lab transcodes the audio when you import it to make it dvd compliant file. Either way this worked great for me and Many thanks to these people that tried to help me and many thanks to the creators of these guides, Reboot and Machine514. Major props to them.
