No, it isn't :) PAL settings are the defaults. > Now I made a movie from the big images (1200x900) without the Z option > and a i got a video without strange artifacts (as the ones i got for the > 780x450 images). > Is there any way to know what image sizes are acceptable to transcode? > Or asked differently, > for a given image size how can i find parameters (encoding etc) which > will create a nice artifact-free movie with the same geometry as my images? Every image size is fine, except for insanely high values (HD resolution are fine, the limit is roughly 1.5x per dimension, ~4x area).
