encoding an Xvid to DVD is jerky

[Flash.Today]

Hi
I have a problem encoding 23.97 frame rate xvid files to DVD.
The problem is a slight jerk on playback not all the time but at regular intervals about every 5-10 seconds.
I have searched through the forum and got some great help but I still can't get rid of these jerks.
My PC is a P4 with 512 DDR.
A typical file properties from GSpot are
Codec - Xvid/yv12 (which are installed)
xy - 592x320 (1.85:1) [=37:20]
FPS - 23.97
Bitrate 876
Qf 0.193 (what ever that is?)
The problem occures when encoding with TMPGEnc Plus, the settings I have used are:
Video tab
720X480
16:9 Display
23.976fps (internally 29.97)
CQ 65 max 8000 min 2000
Main Profile & Main Level [MP@ML]
NTSC
3:2 pulldown when playback
Advanced
Non-Interlace (progressive)
Top field first
16:9 Display
No Margin (keep aspect ratio)

My knowledge on 3:2 pulldown isn't the best but my understanding is that with this form of encoding I am placing tags on the file for the DVD player to decode from 23 - 30.

I have had better results using Ulead Studio 7 and just encoding to PAL DVD but that doesn't explain what I am doing wrong with TMPGEnc.

Any help would be appreciated

I had the same problem a while back and just couldn't figure out what was wrong. Then I read the comment here, uninstalled ffdshow, and problem solved.

If that doesn't do it, try switching your field order around, using interlaced.

Thanks for the reply
Already tried swapping the field order which didn't help will try uninstalling ffdshow, reencode and let you know.

Thanks

Good luck. Just make sure you have the latest XviD codec installed. It was just those 23.97 frame rate XviD files to DVD in TMPGEnc with 3:2 pulldown that were causing me trouble, too.

Hi are you trying to encode to NTSC or PAL. I ask because you said the following.

have had better results using Ulead Studio 7 and just encoding to PAL DVD but that doesn't explain what I am doing wrong with TMPGEnc.

Also change your aspect ratio in your video tab to 4:3 since you are converting to 720x480 fullscreen. Also if you are trying to make a PAL DVD you do not need to do the pulldown (I think) since PAL is 25FPS which is close to 24 (again not sure on this).

Hi,

What a coincidence, i'm having the same exact problems...it's not really a jerk for me but more of a slow down and speed returns to normal. In the end it looks like a jerk, but it's more like a newbie driving a stick shift for the first time

I haven't tried to check if my Xvid codecs were the latest, i'll try tonight to see if that corrects the problem, but for now here are my specs and procedure i was using...

Trying to convert a XVid to DVD. What I tried to do is use AVISynth and VirtualDub's Frameserver to process the avi into CCE. I extracted the audio using VirtualDubMod's stream option, Save as WAV file. I then converted the wav file into a AC3 format using BSweet through AC3Machine. I then fixed the ac3 output file with ac3fix.exe, no bad frames were found! After running VirtualDub's Frameserver I run CCE. I then run AuthorDVD to create my DVD files.

Here are the settings used for each steps in my conversions:

XVid Specs
---------------
Video Codec: xvid
length: 1h30
Frames: 130,699
bitrate: 946kbps
Resolution: 512x384
Ratio: 1.33:1 (4:3)
fps: 23.976
Audio Codec: Mpeg-1 Layer3 48000Hz VBR 2 Channels

AVISynth Script
----------------------
AVISource("VideoSource.avi")
ResampleAudio(48000)
#For 1.33 Aspect Ratio (4:3) or 1.77 Aspect Ratio (16:9),
LanczosResize(720,480)
ConvertToYUY2()

BSweet Settings
-----------------
BeSweet.exe -core( -input "F:\Source.wav" -output "F:\Output.ac3" -logfilea BeSweet.log ) -ssrc( --rate 48000 ) -ota( -d 0 ) -boost( /b=1db ) -ac3enc( -b 192 ) -profile( The AC3Machine v0.4 )

CCE Settings (SP Trial version 2.67)
--------------
Video Mode: MPEG-2 (ES, 1st pass of Multipass VBR)
Bitrate Avg: 6000
Bitrate Min: 3000
Bitrate Max: 8000
No Audio File
Aspect Ratio: 4:3
Video Gop Sequence M: 3
Video Gop Sequence N/M: 4
Check Add Sequence end code
Check Close all GOP
Luminence Level: 0-255
Quantization Matrices: Standard
Quantizer Characteristics: 16
Intra Block DC Precision: 10
Block scanning order: ZigZag
Check progressive frame flag


I've tried diferent bitrates all the way down to 1000 (AVG),interchanged a few settings, but no luck. A lot of these settings i'm not even sure what they do, they are set that way because I use the following tutorial from this site: AVI to DVD MPEG (CCE or TMPGenc encoders) by DJRumpy

Ok, this was long and painfull to post, i hope we get this fixed!

Remove the resample audio line from your AVS script. The athlon bug is only present in 2.5, and below, so you should be able to open the AVS file without it. Also uncheck"Close all GOP"

I'm not sure what this line is for. #For 1.33 Aspect Ratio (4:3) or 1.77 Aspect Ratio (16:9). I let CCE handle the aspect ratio, which in your case is 4:3.

I hope this helps. I have just finished writing a guide for this, but I can't find a good asp host to host it

Here's a link to my IIS server it might take a few minutes to load up since this is my main computer I use.

Check it out and let me know what you think.

I removed the SampleAudio line, I unchecked "Close All GOP"...I even tried installing more recent XVid Drivers (I had old ones from 2003)...

None of these changed my results! Tonight i'll check a different XVid file to see if the source is the problem. I doubt it is since it runs XVid file runs fine on the computer. I might also try a different Frameserver just to see if vurtualDub is the problem. Any suggestion for an alternate Frameserver?

Besides that i dont know much else what to do...anyone have anymore bright ideas pass them on

btw chobo321321, I checked yesterday and your site was not up...maybe you could send me that tutorial via a PM so i can check it out

Thannks for trying
