What entitlements do I have if someone uses my video on Facebook and gets millions of views? I posted a video on Facebook and a page asked if they could use the video. I said as long as I get credit. That video now has almost 10 million views on their page and countless other pages and sites have used my video. Am I entitled to any of the money they make off of advertisements? Are pages legally allowed to use that video if I did not give them license?
Copyright law requires permission of the rights holder to e.g. post material. The terms of that permission could be very complicated, as seen in royalties contracts with publishers, but they can also be simple. If someone asks "can I post your video on my website" and you say "Sure, as long as you give me credit", then they can post the video on their site as long as that say something like "This video was made by Jake" or something like that. There is no exception to permission where permission is retroactively withdrawn just in case it turns out that one can make money off of the video. However: you gave That Guy permission, and that does not mean that the hundreds of Other Guys have permission. So you can pursue all of the Other Guys and demand that they take the video down, or require some payment to get your permission.
No, one cannot safely assume that because some people have done a thing without being sued, that it is OK to do a similar thing and no suit is possible. It is possible that people who upload a video, or a section of it, have permission. It is perhaps more likely that the copyright owner does not choose to sue, for whatever reason. But a different owner of a different video might make a different choice. Uploading a video, or even a section of a video, without permission, will be copyright infringement, unless an exception to copyright such as fair use or fair dealing applies. Such an infringement gives the copyright owner valid grounds to bring a suit. But the owner can choose whether or not to sue. An owner can sue in one case of infringement but not in another, for any reason or none. If the expected damages are small, it many not be worth the time, trouble, and costs to sue. In the US, one must register a copyright before bringing suit for infringement of that copyright, and there is a fee for registration. Some owners feel strongly about the use of their work, and will sue on any pretext. Some may prefer to tacitly support uses that they approve of by not bringing suit. One cannot tell the attitude of a particular owner unless that owner has stated what his or her view is. Short films are just as protected as full-length feature films, and suit can be filed for infringing the copyright on a short film. But the more expensive a film was to make, and the more money the owner expects it to earn, the more likely it is that the owner will choose to sue. Many people infringe by uploading short films or videos, gambling that the copyright owners will never learn of this, or will not trouble to sue. Sometimes such infringers are correct, and sometimes they get sued. I do not understand what the OP means by the part of the question that reads &quot;There should be more detail and complex lines over here&quot; What additional detail is wanted? Who does the OP expect to provide it? What sort of &quot;lines&quot; does this refer to?
No You are limited to “your ... use only”. You are not given permission to make this available for 3rd parties either commercially or for free.
Reproducing someone else's copyrighted material without permission is a violation of that copyright. This includes using it to promote your Twitter account. This is a violation of copyright law and of Twitter's TOS. There may be Fair Use exceptions- this question is arguably fair use. However, it's extremely unlikely your intended post counts. In the case of the image in question, royalty-free means you pay for a single licence for that image and can then use it as much as you want (according to that licence). You can post that image in as many of your tweets as you like- you don't have to pay each time. If you don't want to pay for images you use, use public domain images, images with licenses that allow you to use them, or create them yourself.
If the blog author holds the copyright on the ebook, they can distribute the ebook anyway they choose, either via download from Github or elsewhere, or sell it in an online store. They hold the copyright, they alone can decide how to distribute it. If they also sell the ebook in the Microsoft press Store, they may have an agreement with the store to also allow their own free downloads; it's hard to say without knowing the agreement. If there are ebooks on Githb available for viewing or download, the owner of the Github page should hold copyright of the ebook, both 1) for their own protection against copyright infringement, and 2) to not break GitHub's TOS against copright infringement: https://help.github.com/articles/github-terms-of-service/#f-copyright-infringement-and-dmca-policy
Am I as the user of this site in any way liable if the music turns out to violate copyright? Yes. In a similar way to if I give you “permission” to take my neighbour’s car. Only worse. Because stealing requires intent - you have to mean to do it - while copyright violation is strict liability - if you do it, you’re guilty. If the user that uploaded the item did not have the authority to give the site permission then the site does not have permission and neither do you. If you take reasonable precautions such as performing a reverse image source and verifying that the item appears to be owned by the same person everywhere and, perhaps, reaching out to them then your violation will be an “innocent” infringement which mitigates but does not eliminate damages. The only way to be sure with copyright is to know the provenance of the copyright/licences back to the original creator.
Pay him the $1,000: it's his video so it his money. If you're lucky he won't sue you for copyright infringement. If you're very lucky he won't sue the TV station for copyright infringement (because they would immediately sue you under the indemnity clause you undoubtedly signed when you submitted a video you said you owned but didn't). If you're extremely lucky he might buy you a beer.
You are asking the wrong question. It should be: When you have downloaded the content and metadata, what are you allowed to do with it and what is forbidden? Somebody owns the copyright to the text and images in the thumbnail. This could be the operator of the third party website, or that site has licensed the content from yet another party. You haven't licensed it from anybody. So you can watch the content in accordance with the TOS, and your computer can evaluate the metadata to do it, but you cannot display it on your own site. Details will differ between jurisdictions, of course. You might also be held responsible for illegal content in the thumb you generate. Follow-up: There seems to be some question of what 'thumbnail' and 'card' mean in this context. This answer assumes a somewhat scaled-down representation of the content of the entire page, not just a collection of actual metadata like content length and expiry.
