Converting animated gif to movie format to embed in pdf

[rhaynes74]

Hi, I am attempting to embed a movie into a pdf file using the latex movie15 package.

It doesn't appear possible to embed an animated gif this way. So I need to convert it to a different
format.

convert file.gif file.avi produces a nice movie but again it doesn't embed properly.

.mpg files embed ok but

convert file.gif file.mpg results in a huge loss of quality. What flags do I need to keep the quality?

Or are there other formats I can use?

The question is, is an animation or movie in a PDF even possible. I've never heard of it!

[rhaynes74]

absolutely - just search google for "latex pdf movie15".

Hi Anthony - so I have a way to embed .mov files in my pdf using LaTex.

I have a sequence of 20 (or so) high quality .gif files. I use

convert -delay 200 file*.gif file.mov

to produce the .mov file.

But the quality is terrible - the images (after the 1st it appears!) become very "blurry/grainy", what options do I need to keep the integrity of the original images ?

I am not an animation expert, but you probably have too many different colors from all the images, so that you exceed the gif 256 color limitation. You many need to produce a common color map and use that. see

Hi - the same thing happens if I convert all the images to jpegs first and then attempt
to convert to a .mov file (.mpg or whatever).
