I'm trying to create an avi file from a sequence of images using the
freeware tool pjbmp2avi.exe!
I want these files to be played from a CD. I've tried Cinepak Codec with
the following settings: Compressionquality 100, Keyframe: 1, Datarate:
300 KB/s.
I've also tried other compressions but I can't get it to work. The file
is fine when started from the harddrive. I asume the player loads the
whole thing into memory first. It's just way to slow (0.2 fps!) when
running from CD (40x CD drive).
Any suggestions regarding alternate (free) tools for creating avi files
and which settings should best be used would be VERY helpful.
Thanks a lot in advance,
Rene

I've tried Smaker too. If I create an AVI there are the same options to choose
from. Can somebody explain to me what exactly key frame rate and data rate
options do? Smaker and Bink look very interesting but I don't really like the
advertisement at the end of the movie and I really need a format that will run
from a CD on (almost) ANY system (OK I could make an exe... I agree... great
option...but...).
(By the way what are the differences and advantages between Smaker and Bink
formats? Which one is better for gray scale animations and which for color?)
Thanks for your help!

Bink is better for mpeg quality animations/movies.
Frame rate is the number of frames that are displayed per second. Think of a
flip book. You know the little books that have an image on each corner of
the page. Each images is slightly different (i.e. the location of an arm or
leg, a frown turning to a smaile, etc...) Well if you flip the pages and
look at the images, the images seem to come alive, or animate. The faster
you flip the pages the faster the animation runs. This is the same idea of a
frame rate...
Hope that helps

The term "frame rate" I understand, but what exactly is "key frame rate" ? If I
use different settings for "key frame rate", for example 1 or 10 and keep the
"frame rate" set at 20 per second for instance the speed of the animation stays
the same of course. So what does it do?
What about data rate?
Any other ideas about the avi compression.... what codec settings are best?
Thanks.

If memory serves me right (always a gamble with me...). A "Key Frame Rate"
is a method of creating variable animation speeds in an animation. For
example, lets you have 3 key frames (A, B, C) and 30 frames. From frame A to
B you have 20 frames and from B to C you have 10 frames. So when you play If
the "key frame rate" is 3 key frames a sec, then animation will play faster
over A to B, than it will from B to C. Because A-B has more frames to play
in the same time as B-C...
I hope this is right because it has been a couple of years since I read
anything on the subject, let alone done anything with it....
I hope that helps

warning : All this is IIRC and unchecked
* "key frame" is an uncompressed frame (image) in the resulting file. "key
frame rate" then could be "put a key-frame every [n] frames" or "every
[time]".
* "data rate" setting is a way to limit the size of the file in a particular
but very useful way. If your anim is to be read from a slow device (eg 1x
CdRom), you are limited by the transfer rate of the device. If the anim
exceed that data rate, it will stutter. "data rate" makes the compression
amount vary locally in the anim to guarantee the resulting file never
(nowhere / nowhen) does exceed the data rate.
Povingly,
Philippe

Nope, your memory is defective, you will have to upgrade ;-)
The key frame rate has nothing to do with the frame rate. A key frame is
just a complete frame, while the frames following it just describe the
difference based on this frame. The key frame rate just determines how often
a key frame is inserted.
In practical terms: If you have a lot of movement, a high key frame rate can
help (but will increase the data rate, too), while if you have little
movement from one frame to the other a high key frame rate will just reduce
the compression you can reach. Of course the details are different from one
codec to the next. Note that some modern codecs can insert key frames
dynamically (and support a dynamic key frame rate, too) and you don't need
to bother setting it at all.

DOH!
If I understand this correctly....(brace yourself and try not to laugh).
An example might be, an animation of a man walking across the screen (left
to right).
when the man get to the other side the scene changes. So the key frames
would be the start and scene change frames. All the frame between are just
(data frames?) that describe (or display?) the man walking. since the
background does not change you can get a higher compression of the animation
as a hole?
