SVCD 2 DVD - unsmooth video on NON SVCD DVD-Player

[JohnnyGE]

I would like to transcode an mpeg2 of a SVCD to DVD.
The reason: my older DVD-Player does not support SVCD, but VCD and DVD.

Using the latest TEMPGenc (Audio 44100->48000 und Video: 480x576->720x576) and finally a DVD authoring program to create the DVD structure files, the video of my burnt DVD does not play smoothly in the DVD-Player BUT on PC!!!

The Audio stream is not the problem, but the unsmooth playback in my DVD-Player.


The following information to the basic mpeg2 is given:

Program/System Stream:
- Stream Type: MPEG2 Program Stream(ISO/IEC 13818-1: 1996)
- Flags: Audio Lock, Video Lock
- Video Stream: Stream ID: 0x00e0

Video:
- Stream Type: MPEG2 Video Stream(ISO/IEC 13818-2: 1996)
- Frame Rate (fps): 25.000
- Video Frame Size: 480x576
- Display Size: 480x576
- Interlacing: Upper/Top Field First
- MPEG Aspect Ratio: 4x3
- Video Bitrate (kbps): Max bitrate: 2400 (Variable Bitrate Mode (VBR))
- VBV Buffer Size (KB) : 224
- Profile@Level: Main Profile @ Main Level
- Chroma Format: 4:2:0


THANK YOU!

How did you do the conversion?

@JohnnyGE

Hi!

Since your player can handle VCDs, try the following simple and quick solution:

Use TMPGEnc as follows:

File>>MPEGTools>>Simple Multiplex

Load your SVCD file

Change mode to "MPEG1-VideoCD"

Enter a new filename in the "Output" box

Press the "Run" radio button

(Do not be concerned about any "Buffer underflow" messages you may see)

@Boulder:

Here my settings in TEMPGenc 2.524.63.181:

-> Setting -> Video:
Stream type: MPEG-2-Video
Size: 720x576
Frame rate: 25 fps
Rate Control: Constant Bitrate (CBR)
Bitrate: 2400
VBV buffer size: 0 (automatic)
Profile & Level: Main Profile & Main Level (MPQML)
Video format: PAL
Encode mode: Interlace
YUV format: 4:2:0
DC component precision: 9 bits
Motion search precision: Normal

-> Setting -> Advanced:
Video source type: Interlace
Field order: Top field first (field A)
Source aspect ratio: 4:3 Display
Video arrange Method: Full Screen
! no activated filter !

-> Setting -> GOB structure:
Number of I picture in GOB: 1
Number of P picture in GOB: 5
Number of B picture in GOB: 2
Output interval of sequence header: 0 GOB
Output bitstream for edit (Closed GOP) - no tick
Detect Scene change - tick
Force picture type setting - no tick

-> Setting -> Quantize matirx:
! no changes in the matrix ! - Default
Output YUV data as Basic YCbCr not CCIR601 - no tick
Use floating point DCT (While using SSE, always ON) - tick
No motion search for still picture part by half pixel - no tick

I even tried the PAL DVD template!!!



@setarip_old:
My target is to convert three mpeg2 files to one DVD. So VCD might be possible, but not wanted.



@all:
Who is interested: here is a long (lang) and a short (kurz) version of the file:

... and klick: "GMX MediaCenter starten"!



==> Notice: Each conversion run well on PC, but not with my non SVCD DVD-Player!

My target is to convert three mpeg2 files to one DVD. So VCD might be possible, but not wanted.Perhaps you don't understand that the method I've provided will retain the original MPEG2 quality - without having to do any "heavy lifting" conversion...

[JohnnyGE]

@setarip_old:
I tried the “MPEG1-VideoCD” template und burnt a VCD. The playback in the player was well, but there were some little stripes in fast scenes.
Might a DVD run well with a reconverted VCD MPEG1 stream?
Why cannot the player handle the SVCD stream although each DVD has a mpeg2 stream as VOB?

[Boulder]

Your source is probably interlaced, hence the lines you see. VCD (MPEG1) doesn't support interlacing so your only option is to re-encode. My guess is that you have an incorrect field order which is why the output is jerky.

SVCD has a resolution of 480x480/576 which is not supported by all old players. This resolution is not DVD compliant so the support is not mandatory for a standalone.

Perhaps try using Step 3 of this guide:
http://www.doom9.org/index.html?/mpg/svcd2dvdr.htm

I tried it myself and made a test from the longer clip for you:

[JohnnyGE]

@setarip_old:
The VCD bitrate and VBV buffer size are less than the SVCD. - So why should your method retain the quality of the original MPEG2? Or should I load the PAL DVD Template and force the program to produce an MPEG1 stream?
How can I burn this MPEG1 on the DVD?


@Boulder:
You are right, the source is interlaced, but a default VCD not.
What do you mean by "an incorrecet field order" and where can I change it?
I changed the resolutin many times, even to 720x576 in TEMPGenc. Each output was unsmooth, too.


@Mr_Odwin:
I tried this guide in the beginning. As I have already wrote Boulder, I kept and changed the resolution very often, without success.
I tried your file, too. But the unsmooth video was still there.
- Which program did you use to author the DVD?


@all:
The resolution seems not to be the problem. Transcoding to VCD works well, the original SVCD-MPEG2 stream not.
What is the small differnce of that stream compared to an ordinary DVD?

[Boulder]

What exactly do you mean by unsmooth motion? Deinterlacing will make the video look jerky compared to the original. If you encode to MPEG2 and make a DVD out of the file, you can encode as interlaced and keep the motion as smooth as it is in the original.

I couldn't download any of the samples, could you upload them to some other place, like rapidshare.de or similar? EDIT: it would also be good to see a sample of the VCD you created.

JohnnyGE I checked the lang.m2v sample and it is interlaced - while you did encode it as interlaced you (or TMPG) set the field order wrong.
You have to set it to Bottom Field First (or lower field first) for this clip.

@setarip_old:
The VCD bitrate and VBV buffer size are less than the SVCD. - So why should your method retain the quality of the original MPEG2? Or should I load the PAL DVD Template and force the program to produce an MPEG1 stream?The method I described, which has NOTHING to do with "templates", was established years ago (not by me), to deal with players that could play VCDs but not SVCDs. It apparently changes only the most basic header information to "fool" such players into playing the file, without changing any of the actual playback parameters. So it plays the SVCD, "thinking" it's a VCD.

Once you've followed the procedure I've described, I'm sure you know how to burn it to a CD (no need for a DVD) as a VCD...

[JohnnyGE]

@Boulder:
With unsmooth I mean fast scenes look like a video tape in pause mode.
I will upload the long and short m2v's tomorrow to rapidshare.de.


@communist:
I will change this option and see what happens.

[JohnnyGE]

THAT'S IT!
Communist solved the problem. The source was "Top Field First" although it has to be "Bottom Field First".

@Communist:
Witch progam did you use to identify the wrong fields?

[communist]

Loaded it up in DGIndex, created a d2v file, loaded this in Avisynth and checked with:

MPEG2Source("blah.d2v")
AssumeXFF() #replace X with T / B
SeparateFields()

Check the resulting avs in VirtualDub, the one that has smooth motion is the correct field order - with the wrong field order it will be one frame forwards, one back one forward one back etc.

[JohnnyGE]

Is there a quick possibility (tool) to change only the field order without unnecessary reencoding of the whole m2v?

[Boulder]

You could try ReStream.
