Is there any tools to copy text from video's or images?
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.
I often also want to quickly copy text from images and videos. However I wasn't able to find a good solution on OS X, as procedures like uploading to Google Drive are far too cumbersome.
You can use Optical Character Recognition (OCR) for the job
