Hi
I have another question on this subject.
I checked PNG images of various sizes, and the size returned by
tcprobe is always 720x576:
[EMAIL PROTECTED] ser]$ tcprobe -i big_00.png
[tcprobe] PNG image
[tcprobe] summary for big_00.png, (*) = not default, 0 = not detected
import frame size: -g 1200x900 [720x576] (*)
frame rate: -f 1.000 [25.000] frc=0 (*)
no audio track: use "null" import module for audio
[EMAIL PROTECTED] ser]$ tcprobe -i small_00.png
[tcprobe] PNG image
[tcprobe] summary for small_00.png, (*) = not default, 0 = not detected
import frame size: -g 80x100 [720x576] (*)
frame rate: -f 1.000 [25.000] frc=0 (*)
no audio track: use "null" import module for audio
(I think it is not a coincidence that 720x576 is the D1-PAL resolution..?)
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?
Thank you
Jody
