Is it possible to copy text from image? Is there any tools to copy text from video's or images?
You can upload the image to Google Drive and it will use OCR to get the text from it. Or you can use a specialized software like Abby Fine reader for more advanced work. 

The quality of the text recognition will vary with image quality. I would use a screenshot to get texts from video. 

In Google Drive, you need to set Upload settings below the cogwheel on the right top to „Convert text from uploaded PDF and images files“.  He will copy the recognized text in the document below the image.
