KB-000265: How do I Create Custom Video Speeds for Full OnCue Presentations?

Encoding your presentation to play at speeds other than the default speeds

 

As part of a “Full Presentation”, Impatica OnCue can encode the video component of your OnCue project for playback over dial-up connections (“still”) and at 64, 128 and 256 kbps. To encode your presentation for playback at speeds other than these (typically higher speeds), you can follow these instructions. Even if you do not intend to play your OnCue presentation at any of the default playback speeds, you must first produce your OnCue presentation with at least one of the default speeds selected.

 

  1. Copy your converted OnCue project to a new location on your hard drive.
  2. Open the new copy of your OnCue project by double-clicking the .ipj file contained in the project folder.
  3. Once it has launched, select the “Video Only” project type radio button. The correct video file and corresponding marker file should already be selected. If they are not selected, browse and select the correct video file and corresponding marker file. It is not necessary to select the remaining asset files.
  4. Click on the Video Options tab.
  5. Select the desired Target Connection Speed(s). For connection speeds higher than 256 kbps, select Custom and specify the desired connection speed.
  6. For each selected Target Connection Speed, use the default setting for Frame Rate and Network Overhead (recommended) or select another value for either or both of these parameters. NOTE: If your source video is 30 fps, then select 15 fps as the frame rate. If you are delivering the content on a CD then select “0” as the Network Overhead. 320x240 pixel frame size videos convert best at 960 kbps and should not exceed 15 fps.
  7. Click Impaticize.
  8. While the custom video clips are being created, the next step is to create an “HTML Launch file” that will play your presentation at the higher speed(s).

 

a)      Using Notepad, open the launching html file for your original project.

b)      Within the “VALUE” area for the “SPEED” parameter, insert a comma and the custom speed value that corresponds to each set of custom video clips. If you will only have one speed of video in your final OnCue show then no comma is required. NOTE: The OnCue presentation will begin playback at the first video speed listed in the “VALUE” area of the “SPEED” parameter.

c)      Save the HTML document preserving the original OnCue project name. Make certain the Save as type box is set to “All Files” so that the document will not be saved as a .txt document. Ensure that the file is saved with a “.html” extension.

d)      Place this new HTML launch document in the original OnCue project folder and overwrite the original HTML launch file.

  1. Once the custom video clips have finished converting, copy the .imv files (there will be one clip per slide (12 slides = 12 imv files)) from the “custom speed” project“video” folder and place them in the “video” folder belonging to the original OnCue presentation.
  2. Once the custom speed .imv files have been placed in the “video” folder of the original OnCue show, you can view the result by double-clicking the launch HTML file.
