Xvid - DVD problems. Need detailed help Please!

[tbird2340]

I'm sorry for this post but I've been searching and reading endless guides to no avail. I have some videos that are encoded with the Xvid Codec. Gspot tells me they have a 23.97 FPS, a video bitrate of 975 kb/s, an audio bitrate of 150 kb/s, and a resolution of 640 x 352. The files are roughly 350MB and about 45 minutes long. I want to burn these over to DVD.

Just by using TMPGenc I get an MPEG with no audio. I tried using VirtualDub and extracting the audio to a WAV and then using that as the audio source in TMPGenc. The completed MPG locks on video while audio still plays, skips around, and in some parts correct. What do I need to do!!!??

TPMGEnc Settings:

Video -
Stream Type: MPEG-2 Video for the stream type
Size: 640 X 352
Aspect Ratio: What should this be?
Frame Rate: 23.976

Rate Control mode: Constant quality (CQ)
Quality Setting: 80
Maximum Bitrate: 4000
Minimum Bitrate: 0

DC Component Precision: 8 bits

Motion search precision: Motion Estimate Search (fast)

GOP Structure -
Number of I picture in GOP: 1
Number of P picture in GOP: 3
Number of B picture in GOP: 2

Output interval - 1
Max number of frames - 15

Output bitstream for edit (closed gop) - checked
Detect Scene Change - checked

Audio -
Stream Type - ???
And all other options under audio ??

Again, sorry for the very long post but I wanted to be as detailed as possible. What can I do differently to fix this problem? The source files are excellent quality. Thanks so much!

How big is the wav file when you extract it? If it's about 50-60 megs (well, anything under 100) you're not dealing with a wav file. If it's closer to 500 megs, you are.

If it's under 100, do wav to wav with besweet to get a real wav, then use that in tmpgenc (make sure to use 2lame for the external encoder).

What does Gspot report your audio to be?

[tbird2340]

Wav file size is 484MB.

Gspot has it as 150 kb/s bitrate and 48000Hz.

tbird2340 try this..

I will list everything even if it does seem like overkill.


1. Open your file in VirtualDub, If VDub reports an improper VBR Audio error hit OK (you will need to extract the audio)
2. once opened select File > File Information
3. Under Video Stream make a note of the video size and fps (600x320 23.976fps is an example)
4. Under Audio Stream make sure it is 2 channel mpeg-3 and not AC3

if you have encountered an error in step 1 or your audio stream is AC3 you need to extract to a WAV. Otherwise GOTO step 10.

5. Select Audio from the Pulldown Menu >> Full Processing Mode
6. Select Audio >> Compression
7. Click on <No compression(PCM)> and hit OK.
8. Select File >> Save WAV
9. Enter a savename, Hit SAVE, and wait for VDUB to extract the audio

Now To Reencode the AVI to a compatible DVD standard.

10. Open TMPGENc (assuming you are not using the project wizard I will supply all the necessary parameters).
11. Select your AVI file for the Video Source (and if you extracted a WAV file in steps 5-9 use this as the Audio Source input). select an output filename.
12. Hit SETTINGS.
13. Under the Video tab the following needs to be set

STREAM TYPE >> MPEG-2 Video
SIZE >> 720 X 480 (NTSC 23fps) or 720 X 576 (PAL 25fps)
ASPECT RATIO >> 4:3 Display
FRAME RATE >> 29fps (if vdub reported avi as 23fps) or 25 fps
RATE CONTROL MODE >> Constant Bitrate(CBR)
BITRATE >> 2520
PROFILE & LEVEL >> Main Profile & Main Level
VIDEO FORMAT >> PAL or NTSC (depending on the fps)
ENCODE MODE >> non-interlace
YUV Format >> 4:2:0
DC COMPONENT PRECISION >> 9 Bits
MOTION SEARCH PRECISION >> Motion Estimate Search(FAST)

14. Under the Advanced Tab make sure the following is set

SOURCE ASPECT RATIO >> 1:1 VGA
VIDEO ARRANGE METHOD >> Full Screen(keep aspect ratio)

15. Under GOP structure

NUMBER OF I PICTURE IN GOP >> 1
NUMBER OF I PICTURE IN GOP >> 5
NUMBER OF I PICTURE IN GOP >> 2

OUTPUT INTERVAL OF SEQUENCE HEADER >> 1
MAX NUMBER OF FRAMES IN A GOP >> 15 (for PAL) 18 (for NTSC)

HIT the OK button, and then START in TMPGENc. Sit back and wait for your fully DVD compliant MPEG2 file to be created.

This works for me 100% and is excellent video quality and never any audio sync issues either. Have a go and let me know how you get on.

The above is a fine method but it presumes there are no errors within the actual avi itself. Use this guide to check for bad frames. By the way, steps 6 and 7 are not necessary. Once full processing mode is selected PCM is the default setting.

Sorry for the long delay I've been on vacation.. I just have a few questions before I try this. My video size and fps are 640 X 352 and 23.976 fps..

tbird2340 try this..


1. Open your file in VirtualDub, If VDub reports an improper VBR Audio error hit OK ( I do get that error and I just click "OK" )
4. Under Audio Stream make sure it is 2 channel mpeg-3 and not AC3 (It is.)

13. Under the Video tab the following needs to be set

SIZE >> 720 X 480 (NTSC 23fps) or 720 X 576 (PAL 25fps)

My source file is 640 X 352 and 720 x 480 is not a 1:1 ratio of the 640 X 352 so will that change the look of the video?

FRAME RATE >> 29fps (if vdub reported avi as 23fps) or 25 fps

So I'm supposed to change it to 29 FPS although vdub reported 23.976 fps?

Thanks for all the help.

Mostly it's all OK. But if you're dealing with NTSC Film (23.97 fps) you shouldn't really convert straight to NTSC (29.97 fps), even though NTSC Film isn't valid for DVD, you can either encode it using the 3:2 Pulldown & Framerate of 23.97 (29.92 Internal) options in TMPGenc. Or simply encode as 23.97 then run the resulting m2v file through Pulldown.exe.
