TMPGenc settings ?

[Desperate Jip]

Hi, ...I converted this avi...

File : 658 MB (658 MB), duration: 1:35:10, type: AVI, 1 audio stream(s), quality: 51 %
Video : 549 MB, 807 Kbps, 25.0 fps, 512x384 (4:3), DIVX = OpenDivx v4, Supported
Audio : 108 MB, 160 Kbps, 44100 Hz, 2 channels, 0x55 = Mpeg-1 audio Layer 3 (MP3), Supported

....with TMPGenc+ using the SVCD-PAL template and the following settings...

Non Interlace
Top Field 1st (A)
1.1(VGA)
Full Screen (Keep Aspect Ratio)

I did not alter any other of the other settings apart from lowering the bit rate from 2520 > 1950..(so it would fit on the disc)...
My prob is that when i burnt it it had a jerky playback ..and i thought that u only get that when converting from 1 framerate standard > another...

Any offers would b greatly appreciated ....thx in advance

Jerky playback how?

Is it stopping and starting, or is the scene jittery?

If it's jittery, then I would look at the field order.

[Desperate Jip]

Thx M8, I think it would b classed as jittery and so i will try swapping the field order round. btw, is there a way of checking the source to find out whether it is interlace / non-interlace and which field order it is aswell ...would save me alot of time using the wrong settings in TMPGenc...thx again m8

Or incorrect frame rate conversions ?

Read my comment in that thread to determine what your field order is. Using that method you will also be able to tell whether your source is interlaced or progressive. You know by just looking at the frames. If you get the comb effect where each frame only shows every other line of pixels, then you know you have interlaced footage.

Thx adam, for a very helpful reply. I have reviewed my source as u advised and am pretty sure it is "progressive"-( so as u said, the field order does not matter ). Could u poss know of any other settings that might be causing this jerky playback.
If theres any other info about my settings that might help u help me, plz let me know and i will post them here ....thx m8

Could it be that your stand alone player doesn't like it?
What happens when you play the SVCD back in your computer using WinDVD or PowerDVD etc?

If it plays smooth on the computer but not on your stand alone DVD player then your stand alone DVD player (like 50% give or take of players out there) don't like SVCD.

If however it plays jerky on the computer as well ... then you got other problems.

I agree with FulciLives. If this is the only SVCD you have ever attempted to make, then it seems that your player just does not support SVCDs. Another possibility is that it is having difficulty reading your media.

Is this jerkyness uniform? In other words does it randomly stutter, or is there a pattern to it? If its random then its either the media or poor SVCD support all around.

I know you said you used the PAL template but double check the settings. Its possible you could accidentally overwrite the default settings (hey anything's possible) or perhaps you downloaded your TMPGenc build from a shady site?

In regards to your settings when dealing with progressive footage, there are really only 3 things that could cause jerky playback.

1) make sure aspect ratio on the video tab is set to 4:3.
Using an aspect ration of 16:9 on a SVCD almost always results in jerky playback.

2) ensure that your output framerate is 25fps since that is the framerate of your source.

3) double check your bitrate. If its too high it can cause jerky playback. The 1950 you said you used is definitely low enough, just make sure TMPGenc listened to you. It sometimes has a habit of defaulting back to previous settings.

Thx 4 the replies folks...I dont think its my player as i have burnt a file which i didnt actually encode and it plays fine on my "Cyberhome CH-DVD 400" player. as 4 the jerkyness..well...i notice it more on certain camera pans and so its hard to tell if its random or not ( sorry bout that one )...and as 4 the medium..well...i used "Verbatim" CD-WR which my player says it will happily accept, anywayz i will do some more testing and post back.

[lordsmurf]

As a point of reference, I have a 23.976 AVI NTSC film source that is jerky. The source has issues. Even with TMPGEnc high settings, it won't go away.

The original source was not NTSC film, just the encode I am using as source was done that way.

Nothing can be done but live with it or seek out the original source.

I have a CYBERHOME CH-DVD 500 which is the step up from the 400 model and it is well known that the 500 model does not like SVCD discs. I'm not as sure about the 400 model but since the 500 doesn't like SVCD and it is a step up model ... well it would make sense that the 400 model ALSO has SVCD playback issues.

1 disk or 2? Also, you have a fairy tricky re-size issue to deal with. You definately should letterbox it. Making SVCD's out of DivX eats bitrate due to artifacts induced from the DivX.

I have reviewed my source as u advised and am pretty sure it is "progressive"-( so as u said, the field order does not matter ).

You set it to non-interlaced and arent leaving it as interlaced right? If its progressive, you shouldnt have the option of setting field order.

If you have it on your DVD player, try pausing the video in a scene where you are seeing the jittering. Step thru the scene frame by frame, are some frames duplicated, and I dont mean basicly the same, I mean exactly the same.

[Desperate Jip]

Well Fulci...I really dont get that coz i have just played a section of the disc which i burnt ( but didnt encode ) and as i said b4 it plays super smooth on my Cyberhome 400...couldnt ask 4 better.

1 disk or 2? Also, you have a fairy tricky re-size issue to deal with. You definately should letterbox it. Making SVCD's out of DivX eats bitrate due to artifacts induced from the DivX.

Hehe... that all sounds a bit technical to me , i think i understand what letterboxing is....but have no idea how to do it at all. could u poss point me to a guide or something that is helpful to ppl ( like me) who aint up to scratch with technical jargon.

btw, i aim to put my film on 2 discs.

would be very greatful if u could help....thx

If you use the Project Wizard then TMPGEnc will analyse the source video and make some settings as regard whether the source is interlaced or not.
All automatically

So if I use the wizard I don't need to mess with the interlace/deinterlace setting? I ask because I am having a hard time seeing this comb effect. Is it very obvious? I just want to make sure I'm doing this all right. I am using divix/xvid files and authering as svcd by the way. Thanks.
