theora dev - Jun 2009 - Response to your questions about my suggestions i sent in yesterday

I sent in some suggestions regarding Theora yesterday and I got some
questions from you guys so I'll answer them.?i said this:Theora should
have a feature that disables print screen and video recording software
from capturing Theora videos.?Alot of you asked me about the Fair Use
law. My answer is this. i do know about fair use.?The?problem is, alot of
people don't obey the fair use law as u see with companies getting
youtube to take down full videos of their tv shows.?People can still have
fair use if u disabled printscreen etc. They can get a digital camera and
take a photo of the screen. But it will waste more of a person's time who
uploads full tv shows which is not fair use, and anything that makes it
harder for?a person who breaches the fair use law is a good thing.? Think
of it like plasma and lcd tv's, most of them do not have a hard drive
recorder built into them?to record?tv shows. You have to buy a dvd
recorder seperately. There
is no law that says lcd/plasma tv manufacturers have to have a hard drive
inside?the tv's?so people can record and use the video for fair
use.?Musicians don't have to provide written lyrics to their songs so
people may have to listen to the entire song and write?down the
lyrics?themselves.?Alot of dvd's have copy protection on them so people
don't make?copies and sell them.?So that's why if it's possible,
Theora
should disable printscreen and video capture software from recording
videos using the Theora codec and people can still have fair use. I think
there is some Actionscript code that can disable printscreen etc for
Flash videos so Theora should try.?Some of?you thought my suggestions are
not for this mailing list. i'm sorry for that but i am only a technology
newbie so i didn't know.?i also said this:Theora should have a feature
where when a user plays a video using the?Theora player, the video will
be compressed so the file size is smaller and??it will be faster to load.
The quality of the video should remain the same.??For example, some 2
hour 16:9 Widescreen High definition 1080p videos are??4Gigabytes in
size, so Theora should compress this 4GB video into 100MB??without losing
any quality.?Now for those that found this funny because?you think it's
impossible, well all i can say?is new technologies are coming out all the
time. 100 years ago they didn't even
have cellphones, and now we do.?Just this year, researchers have found a
way to store 100 DVD's of information onto a single DVD that can be found
here:http://news.cnet.com/8301-17938_105-10246057-1.html?So maybe there
is a way to compress a 4GB movie into 100MB without losing any quality.

The reason I found this funny - a) theora is a codec (data), not a
program (code). You should look up the difference. and b) even if it
were code, it is simply not possible for one program to affect another
in this way. For the same reason, I cant send an email that
automatically disappears after 1 week - because it is up to the email
reading program whether it deletes the email or not. Do you understand
this ?

I read the article, they talk about storing 100 regular DVDs on a
special new type of DVD, (which obviously has at least 100 times the
storage capacity).

don't you even read the articles you post 
it is talking about Holographic Versatile Disc see
http://en.wikipedia.org/wiki/Holographic_Versatile_Disc

theora is lossy like Mpeg 1/2/4

if you want lossless use ffmpeg's ffv1

I like that idea. I think seeing as Theora utilitizes compresion
itself already, the fact that it doesn't already shrink a video
normally 4GB down to 100MB just shows that the developers are paid by
M$ and other companies. I like how you say it should do that, when it
sounds like you have no understanding of how compression works. I'll
make a statement: Open Office should never let any document get above
1MB without sacrificing the storage capacity, and should load any
document in less time than it takes for my harddrive to seek to the
spot on the disc. Do you see a problem here?

Now, Theora possibly might be able to give you a 2 hour 1080P video in
100MB if it was just blackness.

It's all about perception. Compress the same movie to 100MB and 4GB
from the original. If 100MB is a tight squeeze, give it to the person
who has never seen a movie before, and they may think it's amazing (if
they can make out the different between a person and a dog in the
movie), while the 4GB might even look cheap to someone else. So I am
proposing to put a 32bit signed integer in the Theora header format,
for perceived quality suitable. Video fidelists might have something
like 0x7EADBEEF and the blind might have 0xDEADBEEF.

FYI: Increasing storage capacity != increasing compression. It's a lot
easier to increase storage capacity than increase compression,
especially without sacrificing quality.

Cheers!

PS: It's okay to not understand this, but I do think you are a little
narrow on this topic for how much you seemed to push this.
