Adding subtitles to a Turkish video

hi, Our video is an interview with specialists at banking sector. They speak in turkish and subtitles will be in english. The hardest part of the film is that you should delete the turkish wordings which we wrote them with animation and write their english version. Please look at the attachment, this is the screenshot of the video to show you the place of the wordings. The bad news is, we don't have the editable version of the film. So you should be very professional to delete it and write the english versions. Thanks
