Video Facts

A large amounts of hard drive space is required for digital video editing

  • One gigabyte (1 GB) of hard drive space will hold approximately 5 minutes of video
  • 5 minutes of HD video can occupy 2-4 GB of space depending upon the format (HDV 720p and 1080i)

 


Exporting Facts

Know your purpose -- You need to know how you will present your video before you export it. Its use will dictate the export options you choose.

  • If you want to show multiple video clips in class consider a DVD
  • If you want to use the video in a PowerPoint presentation then choose To Quicktime > CD quality
  • If you want your students to view it within WebCT then choose To Quicktime > Web quality.

 

Remember, when posting your video on the web size is important! You have to assume that your students will view the video on a slow modem connection so make it a small file size.

 


Size vs. Quality

While size is important sometime a high-quality is more important. If this is the case and you need a high-quality video delivered via the web then consider streaming. Streaming delivers a large video in small, manageable chunks that a modem connection can handle. This allows anyone with any network connection to view the video.

 

Things that effect video file size

  • Length of Video (how many minutes long)
  • Number of Transitions
  • Audio: Stereo vs. Mono
  • Amount of movement in the video (use a tripod when possible)
  • Height/Width of the final product
    • 720x480 for DVD/TV/VHS
    • 640x480 for CD
    • 320x240 for Web
    • DVD/VHS
      • DVD will hold 4.6 GB of video (note: iDVD only hold 1.5 hours)
      • VHS will hold 2-6 hours (not based on file size of video)
