Whenever we embed or encode captions or subtitles…

Whenever we embed or encode captions or subtitles into your video, we’ll need a master video, which requires certain specifications, as follows:

  • The program must be ready to air
    1. Be sure to check the tape specifications
    2. Be aware that Metro Audio/Video clones/dubs your master straight across, thus we cannot be held responsible for off-spec masters.
    3. We urge you not to send us your original master. Make a clone or dub to send to us, so that you can protect yourself from potential damage or loss during shipping.
    4. Metro Audio/Video does not offer technical evaluations. If your presenting network does requires a competed technical evaluation form, you may include this form with your master, and we’ll forward it with the captioned master.
    5. We cannot fix off-spec masters, and will request fixed master if necessary.
  • Have locked pictures, audio and supers
  • Be sure the master is free of hits and distortion
  • Supply bars and tone that match the program video and audio
  • Provide SMPTE drop frame timecode if this is for broadcast. If your master is a NTSC non-drop frame, indicate this on the label
  • Provide continuous LTC (longitudinal time code) on the timecode (address) track
  • VITC on lines indicated by the network (generally 14 & 16 or 16 & 18)
