  How to receive (download) videos on-line for private screening using Ki Pro

  Posted by Craig Alan on September 20, 2012 at 5:56 pm

  We want to organize a small private screening of videos. These will be no longer than 5 minutes each. They will be shot with a variety of cameras and codec’s. What is the best way I can have people send me these videos (on-line) so I can download them, then copy to KI Pro which will be connected to a projector for playback. It’s ok if I need to tell the producers to send the films in a certain codec (must be QT, but will any QT work?).

  I want to retain the best quality possible.

  In order to help clarify the creation of QuickTime files for use with Ki Pro, here are some basic guidelines for your consideration.

  – For applications that can export QuickTime movie files (such as Final Cut Pro 7, Compressor, QuickTime 7 Pro, etc.), choose the appropriate Compressor type – Apple ProRes 422 (Proxy), Apple ProRes 422 (LT), Apple ProRes 422 or Apple ProRes 422 (HQ); for screenings, using Apple ProRes 422 or Apple ProRes 422 (HQ) for best quality would be recommended.

  – Set the frame rate for the exported material to match the source material/edit/timeline: 23.98, 24, 25 or 29.97 fps for 1080p material, 25 or 29.97 for 1080i material and 50 or 59.94 fps for 720p material.

  – Most QuickTime export tools will allow the user to define whether the material is interlaced or whether it is progressive. If you are in a 59.94Hz region, HD interlaced material will be top field first and SD interlaced material will be bottom field first. In a 50Hz region, HD and SD are both top field first if interlaced. If material is not interlaced, do not select any interlaced options and the material will be tagged as progressive.

  – Size is determined by pre-determined standards for NTSC, PAL and HD raster sizes. Select the one that is appropriate for your material. 1920×1080 for 1080 HD or 1280×720 for 720 HD or 720×486 for NTSC SD or 720×576 for PAL SD.

  – Sound Settings should be as follows:
  Format: Linear PCM
  Channels: Stereo (L R) or 2 Discrete Channels (either is acceptable)
  Rate: 48.000 kHz
  Render Settings: Best
  Linear PCM Settings, Sample size: 24 bits, Little Endian

  – Remember that to be visible to the AJA Ki Pro, an Apple ProRes 422 QuickTime file needs to be placed in the Ki Pro Storage Module folder named “AJA.”

  If you have any additional technical questions about using files on the Ki Pro, please feel free to contact AJA Technical Support via phone or email, Monday through Friday, between 9am and 5pm PST.
