When i convert a AVI to SVCD the picture has some digital bl

[kangoll]

i converted an AVI to SVCD with TmpgEnc and watched it on my dvd player the first few minutes was fine perfect quality and all but in some scenes like the fast moving scenes i get some blockiness in the movie is this normal or am i missing some filters or settings that i should of checked? i used NTSC template for the encodings

It is NOT normal for me..
I got a Nintaus dvd player, and have convertet a lot og divx movies to svcd. And it works like a charm. Even if i put up to an hour pr cd, the quality is good. Just watched Driven. It is on 2 cd's and no blocking there. I use the quides on this page to make the conversion. And i use TMPGEnc for converting the movie. Do you remember to calculate the bitrate? And how high is it? I think the lowest i gone is with driven, and it was about 1500 with 224 bit sound. I dont activate any filters.
Give a little more info, and maby a can help.

God luck.

First, it is normal for there to be some blockiness depending primarily upon bitrate. The encoder is trying to approximate how many different colored pixels it can fit into a certain area. The blocks are a result of simplifying the colors while retaining the most pertinent information.
So, instead of a man wearing a charcoal grey suit with millions of shadows, you get a man wearing a charcoal grey suit with only tens of thousands of shadows. The difference lies in the complexity of blending these different colors together.
Now, with high motion scenes, the encoder does the best that it can by finding the median color between two separate items (i.e. a fist and the background)and blending these two colored objects together because it can't tell the difference between a hand and a background. It can only see differences in color. Thus, we have blocks which represent averages in detail.
Possible Solutions:
1)Try setting motion quality to high or highest (a lot of people say that there is no difference, but highest DOES take out more macroblocks).
2)Try playing around with the blur filter on TMPGEnc.
3)Try NTSCFilm. Less frames means more information per frame.
4)Try using a bitrate calculator to see how much video bitrate you can squeeze onto your cds. Then try lowering the audio bitrate to squeeze even more video(you can usually go down to around 128 kbps audio and keep the quality at a decent level)It's a movie, not an album.
It's a bit of a long explanation, but hopefully it's in laymen's terms.

well my bit rate for this movie i tried to squeeze onto 2 74min cds and the highest was 2496 and the lowest was 1783 at 224bit sound
i used 2pass VBR on TmpgENC and i put it on high quality and i still get macroblocks in the movie. is there a gop setting i should put it to to soften these up or should i just go with putting it on 128bit for sound to get more video info per frame
but what is the blur filter on tmpgenc?

[henrik25]

Hmm. Dont know what to say then. I use only one pass, with fixed bitrate, and i dont se the blocks (well maby 2-5 sec on a mavie). I always use 224 bit sound...

Well have you tried another movie??

if it was a d'lded avi, then you will always have problems.....I know I do...some turn out great..others I cant do a thing with them. A dvd rip done by you will be great...a dvd rip done by someone else may not be so great. I have pearl harbor and had to dump it...but my star wars are perfect. just something to keep in mind.
