Microstutter

[arehm]

Here's what I'm trying to do. I'm probably missing something stupid, or serached for the wrong things, but here goes.

I'm caturing via firewire from my DVR (Motorola 6412) to .ts files. I convert the .ts to mpg with HDTVtoMPEG (1.11beta) I then want to convert to DVD spec so I can burn DVD's. I've been using this guide here.

The PQ is excellent, but I am getting bad microstutter and am unsure how to remove it. I have been in contact with the guides author and he has been helpful, but has just noticed the stutter himself ad is also trying to resolve it. Here is the .avs I'm using:


#AVS Script for 720p 60fps source

#Load the MPEG2DEC3 and Decomb plugins.
#Mine are located in c:\avsfilters
LoadPlugin("c:\avsfilters\decomb.dll")
LoadPlugin("c:\avsfilters\MPEG2Dec3.dll")

#Load the video and audio files.
video = MPEG2Source("superbowl.d2v")
audio = WAVSource("superbowl.wav")

#Reduce framerate to 30fps and IVTC
video = video.SelectEven()
video = video.Telecide(0).Decimate(cycle=5)

#Delay the audio (according to delay given by DVD2AVI)
audio = audio.DelayAudio(-0.723)

#Resize the video to make it complient for end product specs.
#For NTSC DVD spec (with proper aspect ratio):
video = video.BicubicResize(704,480)
video = video.AddBorders(8,0,8,0)

#Interleave the video and audio together.
av = AudioDub(video,audio)

#Return the video/audio
return av


Can anyone offer any sugestions? Id i've missed something obvious, please let me know kindly....

Just curious, why do you have the selecteven in there? Telecide and Decimate are enough to do the IVTC. Not sure it will make any difference but I don't see the need for it.

I'm using what he supplied in the guide (read: I'm a n00b!) That's why I'm posting here to see what we can do to improve it.

Try getting rid of it and see what happens, cause its pretty much unnecessary. Just to check, the stuttering doesn't happen in the souce does it? Also, some of the software he says to use in his guide is a bit outdated. You want to upgrade DVD2AVI to the latest DGIndex and DGDecode instead of mpeg2dec3 (both can be found at here (http://neuron2.net/fixd2v/dgmpgdec120rc5.zip)). They work the same as the old software and filter but are much improved.

I'm reencoding with the "offending" :P line removed. Single pass with all the bells and whistles turned off since it's about a 10 minute clip, it'll still take 30 min or so to encode. I tried the program you suggested which was newer, but quenc didn't like the .avs file where it referenced the .d2v file. it works just fine with dvd2avi though.....any suggestions?

[KaiserS]

And you used DGDecode instead of mpeg2dec3 correct? Cause mpeg2dec3 can't read d2v's created by DGIndex. Other then that, I don't see a reason why there would be a problem.

[arehm]

I went .ts to .mpg with HDTVtoMPEG 1.11 beta
.mpg to .mpg with .d2v and .ac3 with DGIndex
ac3fix'd the ac3
headach3 the ac3 to a wav
then i tried to quenc the wav and d2v (mpg)

can you simplify this process?

If you put a source clip on my ftp site, I'll have a look at it. Up to a couple hundred meg is fine.

I'm going to try a few thing first, then i'll u/l something to you. Does anyone out there know where thee is another guide other than the one i pointed to to go from a .ts to DVD?
