Out of synch sound with TMPGenc output with SVCD MPEG2

[giguy]

Hello,
I saw several messages on the forums talking about synch problems, but couldn't quite find the answer to my quetion.

I use Smart Ripper, then DVD2AVI, then TMPGenc to produce an MPEG2 for SVCD. Then TMPGenc MPEG tools to cut it into 35 min pieces. Then VCDEasy to burn. When I play the SVCD, I see a quick succession of pictures of what was the menus on the DVD then the movie starts. By the time the actual movie scenes play, there's a good 20 second sound delay (the picture shows earlier than the sound).

(When I picked my VOB on DVD2AVI, there were 3 sets: vts_1xxxx, vts_2xxx and _3. I picked 2 as it had the longest IFO file, which means it is the main movie. Don't know if that means anything here.)

Thanks
Kevin

which movie did you rip...there are some movies that have a delay...

also, there's a version of dvd2avi that has sync problems when forcing film...

The movie was Sword Fish, My DVD2AVI is 1.86. I did not force film

well...i've done swordfish awhile back, and personally would suggest u to turn on force film and encode as 23.976 fps + 3:2 pulldown in tmpgenc...the quality will be much better than w/o force film

c if doing it this way will give you outta sync audio....

(also, if there is a delay, it usually states that in the audio file name)

I thought you can't use FILM if you want an SVCD? I know pulldown is what happens when you have different input and output framerates, but I don't know how, or why, you would customize it to 3:2?
I tried coding with DVDx, worked. But not sure what's happening with TMPGenc
Thanks

NTSC framerate is 29.97 fps...when you use force film, the framerate you encode at is 23.976 fps...so in order to make it 29.97 fps on playback (as required for NTSC), you need to use 3:2 pulldown. this basically adds extra frames during playback...

but anywayz, 3:2 pulldown + 23.976 fps is usually going to be higher quality than 29.97 fps + interlaced. if you have a chance to do so, which in the case of swordfish, then you should go ahead and turn on force film in dvd2avi...the quality is much better.

dvdx's quality isn't that good...if u want an all-in-one proggie, then dvd2svcd seems to be getting lotta good reviews

OK. I think I'm beginning to understand things better. One more thing: I've been doing something wrong, but can't quite figure what it is: I always get a squeezed in 4:3 from TMPGenc even when I tell it to output the MPEG2 as 16:9
This is probably basic, but couldn't find an answer in the tutorials.

no, no....the output ratio depends on what you're gonna watch your rip on...either regular 4:3 TV or the 16:9 widescreen HDTV...i'm guessing you're like the 99.9999% of us who still have the 4:3 TV. hence, your OUTPUT VIDEO should be 4:3 display NTSC...

your problem most likely lies in wut you put for SOURCE VIDEO. in dvd2avi, there was an "info" box that appears when you make the project .d2v file. that info box will tell you the SOURCE aspect ratio (either 4:3 or 16:9).... this is what you will choose as your source aspect ratio in tmpgenc (either 4:3 525 line NTSC or 16:9 525 line NTSC...i'm assuming you have NTSC DVD) as for IMAGE POSITIONING METHOD, choose either "fit to frame (preserve aspect ratio)" or "full screen (preserve aspect ratio)" depending on which version of tmpgenc u have...

a note on dvd2avi's info box...99% of the time it's accurate. however, there were some times where it screwed up...so if you did everything right, then try changing the source aspect ratio.

I have a regualr TV, but I like to keep the aspect ration to the original 16:9 to avoid distorting the picture.
I must be doing something wrong in the settings.
For example, I was trying to code The Matrix yesterday. The info screen in DVD2AVI said it was FILM with an aspect ration of 16:9.
Then I started TMPGenc, used the wizard. Selected SVCD output, made sure the source is set to FILM and 16:9. Then selected 16: 9 for the output. Tried with/without 3:2 pulldown. Tried "full screen" and "fullscreen keep aspect ration". But no matter what I did, I always end up with a squarish picture with tall thin people. This even happens with 29.97 non-FILM movies. I am just not sure what I'm missing. I looked at the TMPGenc guide here. I think I'm doing everything right, but apparently I am not..

- output is not dependent on the source..it is dependent on the TV you're gonna watch it on...

- so if you have a regular TV, u need to set your OUTPUT VIDEO AS 4:3 DISPLAY NTSC, NO MATTER WHAT

- full screen (keep aspect ratio) is correct

- 3:2 pulldown only goes when you are encoding at 23.976 fps (forced film in dvd2avi)

- interlaced and NO 3:2 pulldown is when you're encoding at 29.97 fps (NO forced film in dvd2avi)

Thanks for the input, poppyhead.
Any suggestions about the out of synch sound I've been getting with TMGPGenc?

if the audio is outta sync by the same amount throughout the entire movie, you can use the audio skew feature in the source range filter in tmpgenc....tmpgenc can start the audio earlier or later in milliseconds (ms)
