Hi, Business A was looking for someone to create a video for them and approached Business B. Business B could not provide this service and engaged my video business. No contracts were signed and I was paid by company B for the work. The video was created 4 months ago and highlighted many of the services that Business A performs. 6 weeks ago, I made a promotional video for my own business demonstrating my video making capabilities . I used 3 scenes (8 seconds) from the Business A video. These scenes did not contain any identifiable features of Business A nor did they contain any people. This video is now generating interest in my services from competitors in the same industry as Business A. I have worked really hard to get my video ranking on page 1 of Google. Business A has now threatened to sue me if i do not take down this video from Youtube. Funnily he has agreed to let me keep it on my website, but I can not have one without the other. Can I use the footage that I filmed even though it can not be traced back to Business A? Thanks.
