>> Thanks. I'd like to say "it was nothing" but it was a lot of time spent.
At <<
i can tell!
>> But what I want to be able to do is produce AVI files that can be
distributed to others. I'd like to keep them in the <10MB range without
sacraficing too much in quality. I just don't understand why Renderize is so
effecient. <<
one might as well ask why any AVI standard is different than another. Indeo
seems very reliable, okay quality, fast… and yet i've had cases where is was
readable by another's player at all.
we're opening up a dreadful can of worms here… that AVI is not a standard,
and neither are CODECs, and neither are truecolor image files (such as TGA)…
one again has to know what kind of system a movie file was generated on, and
will be played on. it's not ASCII text. <gg>
>> Hmmm… The Intel codecs didn't work so well for me. One was too large (26
MB) and the motion was jerky. The other was bad visually. As far as working
with lossy and lossles versions: I understand this and will work this way
whenever possible. <<
much of the practicality of a gievn codec also stems from the task at hand. an
extreme example… Tugboat Willy (first mickey Mouse cartoon). if my foa was to
do only black and white cellular animation, any of these lossy codecs would do
perfectly and the matter would be to use the fastest and smallest options. as
color becomes an issue, we start taking "acceptible losses".
>> Thanks for the tips. Someday I hope to have a PAR and be able to dump to
tape for the final product but for now I have to settle w/ AVI. <<
before you do, you ought to also check out Digital's (PAR makers) new PVR.
