VIDEO FORMAT QUESTION [newbie]

September 11, 2006 | 10:21 am

Hello all!
I need to tell to a video maker wich kind of video format do I need
to import my movie into Jitter and to play with it , projecting the movie back in real time.
I told him it is Quicktime, but would you please list here for me all formats supported, mostly the highest quality formats, considering that i need to project my movie on large walls for a big audience.

Thank you in advance, and sorry for my "newbieness"

ps

i’ve been scrolling jitter reference with no results

Tommaso,

I suspect that there are too many QT codecs for anyone to give you a
quick listing along with the benefits of each. You can find available
codecs on your system listed in Apple’s QuickTime Player Pro when you
export a movie (see options, video settings from the export dialog) or
in various Jitter tools that access the QT interfaces for saving
movies. There is documentation on the web for these various
compression/decompression plug-ins, and plenty about QT at:

http://developer.apple.com/reference/QuickTime/index.html

You might find this useful:

http://mac.sillydog.org/qt/compare.php

though incomplete.

Quality is subjective, of course, and depends very much on what you
want–speed or visual detail, etc.–balanced against CPU usage which
in tuirn depends on framerate, image dimensions, the codec used, and
other factors. There is no "optimal" encoding for all situations.

There has been lots of discussion on this list, too. It seems to me
that the general consensus is that you might as well use .dv for most
purposes, at least for full frame video.

HTH,

i made a list, extracted from jit tutorials, of the available formats:

HEURIS MPEG
TOAST VIDEO CD
QUICKTIME MOVIE
HINTED MOVIE
PICTURE
AVI
DV STREAM
QUICK TIME MEDIA LINK
IMAGE SEQUENCE
M-PEG4

and also a list of codec types:

raw, cinepak, graphics, animation, video, componentvideo, jpeg, mjpega, mjpegb, sgi, planarrgb, macpaint, gif, photocd, qdgx, avrjpeg, opendmljpeg, bmp, winraw, vector, qd, h261, h263, dvntsc, dvpal, dvprontsc, dvpropal, flc, targa, png, tiff, componentvideosigned, componentvideounsigned, cmyk, microsoft, sorenson, indeo4, argb64, rgb48, alphagrey32, grey16, mpegyuv420, yuv420, sorensonyuv9;

this is what i’ll show to the movie maker, hope that this will be enough. About quality I agree with you completely.

thanx for your kind and exhaustive answer

thank you very much

:-)

I also agree. I usually prepare video with Dvpal codec -720×576 (being
in Europe) for large scale projections; it seems to give good balance
between quality and performance on Mac OsX and Jitter 1.5.3.

Ciao,

do it in photo-jpeg
certainly not the apple recommended h264
h264 is good for playing just one file without rx

i’m using photojpeg most of the time and i’m happy
for using aplha layers in you movies use animation+

you want high quality for projecting on large walls
then first check the native resolution of you beamers (most of the
time it’s xga 1024×768)

even better is let him deliver it in dv quality so you can convert it
to the right codec

for general realtime use, the time tested codec is – PhotoJPEG at 75%
quality
note that higher then 75% is exponentially cpu expensive
