July 7, 2006 | 4:57 pm

Hi I recall seeing something similar to this on the mailing list, but
I failed to find mention of it and the solution.

Im using transform_reset 2 on a videoplane and seeing issues wrt
texture quality

here is the patch

#P window setfont "Sans Serif" 9.;

here is a screenshot. Its not an interlacing issue, its a rendering
problem – as the footage renders fine in a ‘non gl’ window vs a video
plane and gl context rendered window.

I recall something about setting a texture mode static to resolve the
issue, but I couldnt get the syntax right.

it might be a codec issue, as it seems some movies I have dont do it

a movie compressed : Apple Photo – JPEG, 426 x 240, Millions @ 15fps
doesnt seem to do it, whereas

a movie compressed : Apple Motion JPEG A, 320 x 240, Millions @ 15fps
does.

I can host the movs if you need it.

OS X 10.4.6 – 4.6b11 and Jitter 1.6

Thanks -

Thanks for the report. I believe for the meantime, this can be solved
by sending the message "sendtexture mode static" we’ll try to resolve
this problem in the next beta.
