TMPGE - How can I elimenate chopyness?

[DUKE107]

Great site, I am playing with SVCD's now in NTSC I have tried several settings to eliminate a slight choppyness when the scene pace picks up. My audio is extracted at 44 and I thought I read somewhere I should lower that to 41 to help with this problem.

DUKE107,
Choppiness or block noise? If you seeing some stuttering in high motion scenes it could be a sign that your video bit rate may be set to high. Also if you're seeing jerky playback during scenes where there is side to side panning you more than likely have the field order set incorrectly. Try reversing it if this is the case. If you're seeing excessive block noise in high motion scenes then the opposite is true of your bit rate settings and you need to up it. I wish could offer more help, but you really need to post more details on exactly what steps you took to encode your file in the first place and describe in more detail of what it is exactly your seeing.

I have been trying mostly, interlace, bottom field first,

I have been trying mostly, interlace, bottom field first, 16:9 aspect ratio, constant bitrate, 2520 motion search very slow, burn 4 x speed plus many variations but cant rid the prob. I have not tried lower bit rate as I thought higher was better. tried variable bitrate and now trying 2 pass

DUKE107,
What is your source video? Is it PAL or NTSC and to what format are you trying to convert to? If the source is NTSC Film (23.976fps) are you using a 3:2 pulldown? Need some more info. If the source is PAL the bottom field would be first, the opposite with NTSC. Try and lay out exactly what your source video is and what format you want to encode to.

It is a DVD ( Canada so NTSC) source - ripped with smart ripper - audio extracted at 44 with DVDTOAVI. I just tried ur idea of lowering bitrate, so I did to 2200 and it was the best so far, almost no sign of blockiness in faster motion scenes. I did notice a bit of blocking in the background i didnt see before but that I could live with. I will try field order A and a 2100 bitrate and a 2300 bitrate to see results. Fortunate for a very fast PC. LOL

PS, I use a Apex AD 1100 W DVD player and understand that it can handle a bitrate of 5000, why is it not better to have a faster bitrate when encoding?

[DUKE107]

PS 2 - I am trying to format to SVCD Mpeg 2

i always get choppiness with field order b. try field order a

I also have an Apex 1100w and I found that the video a bit jerky if I encode at anything over 3000. No problems at all as long as I stay at 3000 or a bit lower. Hope this helps!

How do u encode above 2520 - tpm plus will not accept above that bitrate for me?

Most if not all of the DVDs I get in Canada are NTSC Film. If so, you should select the Force Film option in DVD2AVI. Then use the NTSC Film template in TMPG. If you don't, the whole film looks choppy but it is most noticeable when there is a lot of motion.
