Using the Clipstream™ Video Premiere Plug-in

It is advisable to print out the Clipstream™ Video Technical Guide document for easy reference while encoding. In the case that the preset settings are not preferable, the Clipstream™ Video Plug-in settings can be manually configured to adjust to the exact desired specifications. Please follow the recommendations below for more detailed information on how the settings interact.

Adjusting Plug-in Settings

There are many factors to consider when selecting custom settings or deciding to load one of the pre-set Clipstream™ Video Premiere Plug-in settings. The ability to play a movie smoothly may need to be compromised to allow playback across a variety of connections. Uploading and testing may need to be performed more than once in order to arrive at an acceptable video for various connection speeds.

Step-by-step:

Audio Settings:
When creating a Clipstream™ Video movie, the audio settings must be selected with the video quality in mind. If the decision is to select better quality audio, the quality of the video will need to be slightly adjusted accordingly. In general, the audio settings in the pre-set settings files (and in the table below) are appropriate for the related speeds.

  • Set the rate to 8000 Hz
  • Enhanced Rate Conversion; Be sure to always select 'Best' from the pull down window. Otherwise, the result will be poor audio quality with a lot of ringing, hiss, etc. Also note: there is a bug in Premiere whereas it will not use the new setting after a movie has already been exported without Best selected. Premiere must be restarted and the setting changed to 'Best' if something such as 'Good' was previously selected. View a Screenshot.
  • Click Advanced. Select the Audio Data rate and Optimization. If the file has speaking in it, it is advisable to try 'Voice'. Voice may not provide good results at lower bit rates (8-12)
    -After configuring advanced audio settings (click to view), Premiere 5.x will crash during the next usage (due to a bug in Premiere) unless the preference file prem50.prf is deleted before restarting. Remove the Preference file Prem50.prf (click to view) before launching Premiere again to resolve the problem and avoid a crash. Default path: {C:\program files\adobe\Prem50.prf}.
    ***This problem has been resolved in Premiere 6.0. We strongly recommmend that users of Premiere 5.xx upgrade to Premiere 6.0.
  • Connection Speed minus audio data rate divided by 8 equals data rate. Therefore, data rates should coincide with each other (example: for a 56k sample, if the audio data rate has been set at 16, the data rate should be set to 4)
  • Here are some general guidelines for Audio settings at various speeds:

8. Special Processing. Click modify.

  • Premiere has a few features that will be found useful during Clipstream™ Video Encoding. First note that 'Better Resize' should be selected.
  • In some cases, it is also necessary to check the box at 'Deinterlace'.
  • In the case that the video is too dark or too light, the gamma can be adjusted. (use the preview screen to determine desired brightness) Note that adjusting gamma can affect the ultimate image quality.
  • There is a preview screen with a seek bar at the top of this dialog that allows you to view your video file here. Adjust the various settings there to crop unnecessary and unwanted pixels from the file.

9. Click okay and then Save after double-checking your settings. Save your Clipstream™ Video file as *.vcs to the desired folder.

10. The Plug-in will prompt you to visit the Clipstream™ Video Applet Code Generator. Generate applet code to place in your html document.
