Square blocks during playbacks

[stevemei]

I'm using TMPGEnc for encoding. I am getting square blocks during playbacks. I am encoding SVCD at 2300 bit rate. Are there any setting changes in TMPGEnc to get rid of them ?

Thanks for your help

i need way more info, bud, like the following-

U playing it back on home dvd player or pc?

Are the blocks bad quality blocks, interlaced blocks, or damaged video\cd blocks-----(these types of blocks are green\purple and so on ONLY on home dvd player units)

[stevemei]

These blocks are scattered throughout the picture when view on the TV screen. These square blocksappear and disappear. They also appears to shift colors and turining lighter than darker.

I encode the movie using a D2V file. I have tried making XVCDs using the 720x480 resolution. I've also used the standard 480x480 resolution. I encode at a Constant Quality bitrate of 2300 at 100 quality. I have also made changes in the Quantize Matrix Tab by checking the soft block noise box and tweeking the intra box and non-intra box to 100.

Are there any setting changes I need to do.

I do notice the blocks do get smaller when I encode at 2520.

I would appreciate any help.

Thanks
Steve

ok, i dont know if they fixed this for new versions of tmpgenc but v 2.02 i know and lower for a fact that if u set the quality to 100, blocks will ALWAYS appear no matter what ur bitrate is.

Try lowering it down to 65.

Now, when u say lighter and darker, make sure u r not running it thru ur vcr, even though some vcrs decrypt it quite well, u can still have light\dark phases and static lines slowly going up the screen.

Now, i see these are normal blocks so this is easier.

These blocks should only appear when there is motion.
If i were you, i would suggest first, practicing encoding at 352x240 standard vcd resolution.

You will get a nie picture indeed but not as crisp as dvd, as conpared if u used svcd which is at 480x480.

For the processing power and time needed to get good pic out of 480x480, u better have a fast machine.

U would have to do 2 pass, highest quality(highest is beter than high, noticable on fast motion scenes and longer movie durations) and that should be the most part of it.

Hope that helps
