It is common that TV channels or internet TV channels (e.g. those regularly post their shows on Youtube) use materials from other sources. For example, displaying photos from the internet, parts of videos already posted on Youtube and other websites, etc.I am curious how the copyright permission is handled for using copyrighted materials in videos.In the past, major TV channels were only in the market, and they had their own reporters and photographers to make their materials. Nowadays, there are many small channels (even personal ones), and I doubt if they take of care of copyright issues at all.As a more specific example, how to obtain right to use a part of a Youtube video in an online show, which will be posted on Youtube ?
Usually in the video you give some kind of credit for music and photos etc used but it all depends on your endgame. If you are producing videos to sell a product or service then I strongly suggest you buy royalty free music at sites like pond5.com and use photos or video from sites like shutterstock.com to avoid any legal issues. However if you are just posting fun videos and using content from the web it should be fair game. Just use your best judgment. I personally stay away at using other peoples videos unless I get written permission. I know many don't but that could lead to ugly law suites in the future and I just wouldn't risk it. I hope that helps.
