Royalty Free AV Data for Benchmarking?
Foredecker asks: "I'm developing some audio and video encoding benchmarks. (yes, they will be open source), and I need royalty free high quality audio and video. Unfortunately, I can't simply rip CD's and DVD's for distribution. I need to distribute the content with the benchmark to provide a consistent data set. I'd like both stereo and 5:1 audio and regular and high-def video. Anyone have any ideas where I can get such content?"
All over the U.S. aspiring young "film people" make all kinds of cute little shorts. They would love the exposure; most would be glad to release under the GPL, or GDL, or whatever public license you want.
If you need some good cartoon footage I saw a link to a short with a little rodent scurrying about the house in a translucent ball around here somewhere....
Try going to the forums area of www.CGTalk.com and ask over there. It's a website dedicated to computer generated art and animation. There are lots of professionals there who work at tv/movie/game studios. I imagine you'd be able to find people willing to donate what you need. (or at least put you in touch with somebody who might)
;)
It's worth a shot.
"Derp de derp."
the public domain? try educational type videos, etc
http://www.archive.org/movies/movies.php not that HQ (mpeg2), but still...
What about, Archive.org -- they seem to have a large selection of Public domain videos, who knows if they are any recent ones though..
Free means no restrictions, ironic the FSF's GPL forces restrictions, isn't it? What's your definition of free?
Fair Use: Overview and Meaning for Higher Education
Copyright law begins with the premise that the copyright owner has exclusive rights to many uses of a protected work, notably rights to reproduce, distribute, make derivative works, and publicly display or perform the work. But the Copyright Act also sets forth several important exceptions to those rights. Key statutes make specific allowance for concerns such as distance learning, backup copies of software, and some reproductions made by libraries. The best known and most important exception to owners' rights is fair use.
The Fair-Use Statute
The following is the full text of the fair-use statute from the U.S. Copyright Act.
Section 107 of the Copyright Act of 1976. Limitations on exclusive rights: Fair use
Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified in that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright.
In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include --
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors. (Emphasis added)
The Meaning of the Four Factors
While fair use is intended to apply to teaching, research, and other such activities, a crucial point is that an educational purpose alone does not make a use fair. The purpose of the use is, in fact, only one of four factors that users must analyze in order to conclude whether or not an activity is lawful.
Moreover, each of the factors is subject to interpretation as courts struggle to make sense of the law. Some interpretations, and their subsequent reconstruction by policy-makers and interest groups, have been especially problematic. For example, some copyright analysts have concluded that if a work being used is a commercial product, the "nature" factor weighs against fair use. By that measure, no clip from a feature film or copy from a trade book could survive that fair-use factor. Similarly, some commentators argue that if a license for the intended use is available from the copyright owner, the action will directly conflict with the market for licensing the original. Thus, the availability of a license will itself tip the "effect" factor against fair use. Neither of these simplistic constructions of fair use is a valid generalization, yet they are rooted in some truths under limited circumstances. Only one conclusion about the four factors is reliable: each situation must be evaluated in light of the specific facts presented.
The following are brief explanations of the four factors from the fair-use statute. All four factors which affect fair use must be taken into account before reaching a conclusion.
Purpose
Congress favored nonprofit educational uses over commercial uses. Copies used in education, but made or sold at monetary profit, may not be favored. Courts also favor uses that are "transformative" or that are not mere reproductions. Fair use is more likely when the copyrighted work is "transformed" into something new or of new utility, such as quotations incorporated into a paper, and perhaps pieces of a work mixed into a multimedia prod
working in a video/image compression lab, we always ran into that problem of not finding GOOD source that hasn't been messed around with or other artifacts.
our solution to getting Hi-Def material? Sony's HD-CAM a little pricey, but damn, even george used it for a movie.
you just can't go wrong here.
We've been collecting what freely-redistributable clips we can find at media.xiph.org. There's not much there, but it's still worth a look. Particularly interesting for your case are some public domain HD test clips made available by TU München LDV. Of course, they're quite short given the size of uncompressed HD frames.
Please let us know if you find anything else, that's exactly what the collection is for.
In general, the suggestions of contacting copyright holders for permission is the best one. There are various collections of test clips and movies online, but they're generally either small and without audio, or already compressed. Plus, the more content we get under free licenses, the better the world will be. :-)
The Internet Archive does have a collection of movies with contact information, so that might be an easy place to start.
Good luck!
I believe they use some sort of per-frame based compression, similar to MJPEG.
You are not alone. This is not normal. None of this is normal.
