I have to deal with similar

I have to deal with similar situations quite often. The person usually sends me the link for the video on YouTube. I usually never trust the version they send or link me to. I search for it myself and use a YouTube downloader program. The program analyzes the video and gives me the options for which one I want. I then download the highest one possible and then make changes and then re-render using the presets (YouTube or Vimeo) in Adobe Premiere. I have done similar process in FCPX
