Compressing Video for TaskStream

Currently, TaskStream allows users to upload videos up to 100 megabytes in size. Therefore, in order to upload a video to TaskStream, you will need to compress the video to make sure it is smaller than 100 megabytes in size.


Below is a list of issues that may prevent you from uploading your videos on to TaskStream:


  • Videos over 100 megabytes in size

  • DVD video.  DVD video is usually much larger in size and cannot be uploaded directly into TaskStream using conventional means.  The DVD must be transcoded into a compatible digital video file, such as .wmv, .mov., or mpg.

  • Streaming video from sites such as YouTube cannot be uploaded to TaskStream as is.  It can be embedded if you have knowledge of HTML, but we do not recommend embedding video since it is not archival, meaning the video may be removed from the streaming service.

  • Upload size restrictions from your Internet Service Provider (ISP).  For more information on your upload size restrictions, please contact your ISP.

If your video is larger than 100 MB in size, you will need to compress (make smaller) your video to ensure that you can successfully upload your video to TaskStream. Luckily, all the tools to compress video files come free with your computer, either PC or Mac.  There are also free programs available for download. A basic web search for compression tools should give you more options if you do not wish to use the software listed below.  




How to Compress Video using a PC

1. First open up Windows Movie Maker from the programs menu.


2. Click the Add videos and photos icon. Then choose the video file you want to compress.

3. Your clip will show up on the right with a preview window on the left.




4. To trim the video, click on the edit tab. Click and drag the black bar to the point where you want the clip to start and select Set start point. Then click and drag the black bar to the point where you want the clip to end and select Set end point.

5. Once you have the clip that you want to upload to TaskStream go to the Home tab and select Save Movie. You will want to create a custom setting in order to make the file under 100 mb.

Click here to create a new setting.

6. Set the width to 320 and the height to 240. You can set the bit rate as low as needed to make the file small enough. The estimated file size per minute is at the bottom, use this to determine how low to set the bit rate. A bit rate of 100 should guarantee that it will be small enough. Click save to save the new settings.



This gives you an estimate of how large your clip will be.

7. Give the settings a name such as TaskStream and save the setting. You can then close the custom setting dialog box.


8. Click on Save movie again and select your custom setting.



Click here to use new setting.

9. A new window will appear. Name your file with the date, level, title

  1. Choose where you will save your movie and click Save.




Trouble shooting – if you misplace your video file, use the Finder to locate it.

You can now close Movie Maker and open TaskStream to upload the video. See next page for directions.

UPLOADING TO TASKSTREAM:


  1. Go to TaskStream.com & look under My Programs or My PACT.

  2. Click on your PACT program (or other drf). -- PLC 400 has its own TaskStream program.

  3. Click on the task or area you are working on. (PLC 400: Weeks 10-12 for the Video Monitoring Project)

  4. Choose Add: Video (bottom left).

  5. Click Browse to find your file (on your computer). A screen will pop up. You usually can find movies by scrolling down to the movie icon.

  6. On the pop-up screen listing your files, find yours and click Open.

  7. On the main screen, click Add File

  8. Click Save & Return

  9. Double check that it worked by clicking on the movie and making sure it plays. (You will need to download a free copy of Quicktime if it is not already on your computer.) Note: If you can’t hear the sound, go to your computer’s control panel, select Sounds Speech and Audio devices, and make sure that it is not on mute & the sound is turned up.

  10. Follow the same procedure to attach your Commentary/Reflections as a Word Document.

Trouble shooting: If you have trouble uploading your Quicktime file to TaskStream, it is probably too large. There is a 100 MB limit for any single file. Go back into i-Movie or Quicktime Player and save a copy as web or low broadband quality, then upload. You can also contact TaskStream for hints on how to reduce file size.

Reminder: Once you are finished with your complete teaching event or Project, be sure to go to the Scores/Results tab and submit it for evaluation. If you are not yet finished, you can use the comments tab & click on “Request comments” to share it with a reviewer.

Last Step: DELETING VIDEO FILES FROM THE COMPUTER

Once finished converting your work & uploading it to your TaskStream PACT drf, check to make sure it plays. Then delete the files off of the computer & empty the computer trash (You may wish to keep a back up on your flash drive.) To delete files:



  1. Use the Find function to search for the title OR go to where movies are kept in the file directory.

  2. Delete the files (select/highlight file & press delete or drag to trash).

  3. Click on the trashcan icon on the bottom & chose “Empty Trash” from the scroll down menu.

* Privacy Issue: If you are using a public computer such as those in the LARC lab, be extra sure to delete all of your files. The waivers parents signed are for specific limited use only. Your video clips should never be open to access by the general public nor should they be used for job interview, etc.
