The Brackley Drive-in has a digital projection system that requires media files in the DCP format to project. This page outlines how I helped them convert animations from Animoto.com for things like "Show Starts in 4 Minutes" into DCP.

Save Animoto File

  1. Save the Animoto file as an M4V file (select Actions | Download and select the highest resolution you have access to).

Convert Audio

  1. Load the M4V file into Quicktime and select File | Export and then Audio Only to save the file as an M4A file.
  2. Load the M4A file into SoundStudio.
  3. Select Audio | Mixdown to Mono
  4. Select Audio | Sample Size | 24 bit to convert to 24 bit.
  5. Select File | Save As and save as a 24 bit WAV file.

Convert Video

  1. Load the M4V file into GraphicConverter, a Mac OS X graphics application.
  2. Save the M4V file as a series of TIFF images from inside GraphicConverter (File | Save As and then select TIFF and Export All Available Frames).
  3. The result is a folder filed with TIFF images.
  4. Download and install OpenDCP.
  5. Follow the instructions here.

Notes

  1. In OpenDCP you need to prepare two MXF files, one for audio and one for video.
  2. We ran into issues with the audio MXF -- OpenDCP needs mono audio files, but even with two mono files, one for left and one for right, sound on the projection system was still only being fed to the right channel. Still unresolved.
