Shooting Your VideoShooting Your Video
• Shoot to edit
» Always consider how your current shot is going to fit into the overall sequence
» Include a few seconds of “video slop” before and after each shot
» Consider headroom and the rule-of-thirds when framing your shots

• Wear headphones to monitor audio
• Use a tripod and limit zooming/panning
• Level the tripod and camera
• Be careful using autofocus
• Set the camera white balance

Capture Your Video to a NLECapture Your Video to a NLE
• iMovie, Moviemaker, Premier, and Final Cut Pro can all capture & import video
• Most cameras now have a firewire/i.link port for off-loading video
• Either import individual clips from your HD or capture them directly to the NLE
• Captured clips should always be given meaningful names

Edit To Fine-Tune Your StoryEdit To Fine-Tune Your Story
• Editing “shapes” the story and provides emotional impact
• The storyboard should be used as a guide to fine-tuning your story
• Transitions and effects are fun to play with but their use is best kept to a minimum
• Adding a music track to your video can greatly enhance its effect

• You can “sweeten” the sound by using a normalize filter on your audio
• Adding titles not only identifies the subject of your production but also serves as an important way to highlight your student’s participation

Export The Final ProductExport The Final Product
• Most output will require compression
• A codec is software or hardware that enables Compression and DECompression of audio and video files.
• Must balance file size, bit rate, and quality
• All codecs are either Lossy or lossless
• Contained within software “wrappers” • (such as QuickTime & AVI)

A Few Words About Bit RatesA Few Words About Bit Rates
• Audio (MP3)
• 32 kbit/s — AM quality
• 96 kbit/s — FM quality
• 128–160 kbit/s — Standard Bitrate quality; difference can sometimes be obvious (e.g. bass quality)
• 192 kbit/s — DAB (Digital Audio Broadcasting) quality. Quickly becoming the new 'standard' bitrate for MP3 music; difference can be heard by few people.
• 224–320 kbit/s — Near CD quality. Sound is nearly
indistinguishable from most CDs.

Project Ideas For Your Classroom
Things to consider

Video stylesVideo styles
• Instructional – talking head speaks directly to the camera and shares information
• Situational – “candid” shots of classroom activities
• Scripted narrative – students serve as actors and must memorizer their lines
• Voiceover – no actor dialogue. Could be stills or video

Production ConsiderationsProduction Considerations
• One camera or two?
• Wireless or on-camera microphone?
• Ancillary light source or ambient light?
• Location, location, location!
• Copyright concerns
• And what about release forms?
