Cinelerra: artifacts in resulting DVD mpeg
I have Mandriva Linux 2008.0 x86_64 PowerPack on a Dell Inspiron 1720 notebook with Cinelerra from the Penguin Liberation Front cinelerra-2.1-1.svn1008.1plf2008.0.
I want to render an mpeg-2 movie from my JVC Everio GZ-MG505 harddisk camcorder to a format for DVD. I follow exactly the manual of Cinelerra CV version 2.1: 20.9 Making a DVD 20.9.1 Rendering to mpeg2 20.9.1.1 yuv4mpeg pipe through mpeg2enc Copy in ‘~/cine_render.sh file’ the following lines: #/bin/bash mpeg2enc -v 0 -K tmpgenc -r 16 -4 1 -2 1 -D 10 -E 10 -g 15 -G 15 -q 6 -b 8600 -f 8 -o $1 I added -M 3 to improve performance on my Core 2 Duo T7300 processor. I played with -q (3 and 8) and -b (11000) parameters after reading the manpage of mpeg2enc. The problem: there are horizontal artifacts in the rendered mpeg in a certain scene. I can describe it as a horizontal line with the image below the line not corresponding to the image on top of the line. No block but line artifacts that are very disturbing. Did someone struggle with the same and found a solution? Thanks. |
