SVCD blockiness

[spenney]

I've converted some DV that I'd shot to the SVCD MPEG-2 standard.

When I play this SVCD on my stand alone DVD player, most fast left-right movements appear momentarily blocky. Vertical movements and slow left-right ones are fine.

What gives?

Most of the time when a camera Pan's back-and-forth the file will get blocky in that scene. It could be also due to a low bitrate that the file is getting blocky. I have the same problems as you and so do other's on this board. Try searching your problem and see if you find good answers. :P

Did use DIS in your fliming ?
Turn it off, see wether it help ?

What bitrate are you using ??

[SingSing]

The dv cam export avi over the firewire.
I encoded it to standard 480x480 2520kpbs SVCD.

@SingSing,
Not to start another war over CBR vs. VBR, but you might want to try doing some test encodes using 2 pass VBR even if the max/min rates are the same. The should result in better bit rate allocation in high motion scenes reducing the amount of block noise.

Normally, after editing, home video is normally pretty short.
2520kpbs can get your 40 minutes, on SVCD.
This is more than enough for most event, unless this
is a 2 hour parade.

Hi SingSing
Maybe you could try 352x480 2520kpbs instead. It is a little lower on resolution but that may offset the macroblocks that you are seeing.

I was doing quite a few CVD before. I do think visually
352x480 look a bit better than 480x480, maybe because
352 is half of 704 ( DV and DVD horizontal resoltuion ).

But I don't think it ever help to reduce blockiness.
