Hi,

What to do when I got horrible blocks during payback of the movie ? I tried to change the settings of DivX5 decoder but in vain.
I also tried to re-encode the part of the movie which contains these blocks but how to do this in GK ?

Thanx

you didn't really give to many information with your question so this going to be a bit a guessing game :-)
please provide more information like movie titel, bitrate, how many cds, audio settings (mp3, ac3 ; bitrate etc)

ok as i believe this was an action movie you probably tried to encode to one cd this is probably normal, just because you had to reduce the resolution and the bitrate significantly.
if there's a lot of movement in a movie, it need's quite a bit of bitrate. so in an action movie with a lot of fast scenes you might consider using two cds in order to get a better quality. if the movie is too short to be resonably fit onto two cds you might consider adding another audio track (like comentary or another language)

anyway with re-encoding you won't have any luck, it almost always reduces the quality and since you can't increase the bitrate anyway(because it wouldn't fit one cd) it wouldn't make any sence. even if you could, you can't really increase a videos quality by reencoding, since the quality has been wasted already.

the only thing you could do is to do the whole encoding process again, this time choosing two cds.

the other possibility would be, if there's only one difficult to encode scene, that you redo the whole encoding, but choose 2 pass encoding this time. this let's the encoder use more bitrate in the one scene that it probably doesn't need in other scenes anyway.

hope that helps
