strange bit noise problem.

[thegecko]

i got a mpg2 file. ive checked it with bitrate viewer and it says average of 2400 and max is at 2900

so i set up tmpg to convert to full dvd using CQ = 75 and max = 3000 min = 300

thing is im getting block noise that isnt ther eon the original.

even tho my max bitrate setting is pretty high im still gettting noise in higher motion scenes,

any ideas guys?

Here's an idea, don't convert.
There are several guides on putting SVCD video onto DVD, plus a tool (SVCD2DVDMPG) specifically designed to help with this. Most DVD players will handle this OK even though it is not fully DVD compliant. Give it a try.

BTW, the appropriate guides are in the AUTHOR section <======

yup ive already tryed those but just get a little screenw ith movie in the corner and the rest is all pixelating green blocks.

Thats a shame.

In that case, I suggest a higher max bitrate. If you think about it, to get the same quality as the source (if this were possible), you need the same number of bits for each pixel for each frame (average anyway). You are going from 480*576 (SVCD res) to 720*576 (DVD res). You are also going from a max of 2900 to a max of 3000. The increase in bitrate is not enough to cope with the increase in resolution. Do the math and find the max bitrate you need.

Another option is to use 2-pass VBR. In this case, do the mats on the Average bitrate required, as well as the max.

Hope this helps.
