How do you handle multiple movie formats in Jitter

Hi . .

I have a piece I've completed that uses different QT movies from multiple sources including video I've shot and clips I've found on Archive.org and others. the piece works fine and actually looks decent but I'd like to get at the core of the best way to optimize visual clarity in a situation like this.

The majority of the movies are: AIC/512X384/Millions/29.97

others include:

H.264/960X540/Millions/24
Mpeg-4/640x480/Millions/25fps
DV/720x480/Mills/29.97
photo-jpeg/320x240/Mills/29.97

jit.qt.movie is set to play 512X384 and everything is being rendered on the graphics card using jitter shaders and jit.gl.videoplane.

I'd like to record the piece using jit.vcr which is set to 512X384

Anyway, how do other people handle a situation like this in order to get the best image resolution? again, its not a huge deal but I'm curious. my thought to experiment is too convert all of the movies to

AIC/512X384/Millions/29.97

and see what happens.

thanks /

Cycling mentions this in jitter reference.

If you haven't seen it I've pasted the link below, the section on codecs and dimensions gets at your question.
https://cycling74.com/docs/max5/tutorials/jit-tut/jitterappendixa.html

That section of the reference hasn't changed since I started using Jitter, so the idea of processing time and cpu power might have been totally outdated.

In the past I've always used quicktime to encode videos with the Jpeg codec.

Let me know what you come up with.
