Try zipping that quicktime file. I understand you are a computer science major. Then you know that quicktime uses heavy compression. Which in it self is like being zipped. I don't know if they teach it at the school you are, but compressing compressed files is to hard. When you compress these heavily compressed files, all you are doing is compressing the header info. I hope you understand.
oh yeah, i just compressed it, and you save just under one meg.
Quick time is the most complex compression of video. As a matter of fact, it plays different on different machines. The slower your machine, the less decoding will take place. Thats why some people on this forum are suprised by the screen caps. There machine can't decode the compression fast enuf. Dont argue this point jedi. you are in my territory on this. Doing webpages is my job. And i already have my degree in computer SCIENCE, with a minor in math. So i know THIS
you can't argue about Quicktime being the most complex compression of video. the file format is proprietary, nobody (except apple) knows what kind of compression techniques are used.
MPEG4, and in particular XviD, offers the best compression these days. it even uses motion prediction/detection and psycho/neuro-based (forgot the exact name, the idea is this: certain things, that cant be accurately processed by the human brain, are compressed more aggresively without noticable difference) compression.
Check your facts, Quicklime does use MPEG4. Then they tweak it. It.s no accident that most movie trailers are offered in quicklime. Apple is the industry leader when it comes to production. There are two schools of thought on compression. loss of quality and utilization of hardware.
Real loose quality, so that slower computers and faster computers see same image. Although with a real server you can compress various levels of quality. Apple uses the computer to decompress the image. slower processor see lower quality images. Divx uses a combo of the two. Some loss of quality, ans some use of computer power.
There is a race on for compression. The one thing that all CEO's of tech companies agree on. The person that developre the latest and greatest compression will be richer than Gates.
To prove this point, pause any video, especialy full motion video.
