4. Scripting
Edit Scripts and Outlines: The “Paper” Edit
An edit script or outline communicates a general idea about how the video might flow.
This step, although optional, can make sure the structure of the first rough edit matches
your vision. To prepare an edit script, simply copy and paste the complete information for
each clip (the full line of text) into a new document in the order you wish.
* Prepare visual elements
o Provide existing print or other graphic designs
o Create a list of participants and other titles
o Write text for full-frame graphic screens
o Prepare a full list of credits including all participants
* Music preparation
o You can choose music from several libraries for a reasonable fee
o Remember that commercially-recorded music is protected by
copyright
o Use a rights-clearing house to purchase rights
o Use local musician’s recordings for a small fee or in exchange for credit

• more…

7. Editing - Digitizing
Capture your video elements to your computer
• From Tape = real time
• From Disk = time varies
- Do you need to use a special application or
additional transcoding to be able to use with
your editing suite?
• Importing other files: music/audio, images, etc.
* Stay organized: use folder/bins, label as you go

8. Editing - Basics
Parts of Editing software:
(terminology may vary depending on software used - below is Final Cut Pro terminology)
• Browser - shows and organizes your source files/clips
• Timeline - where you piece it together
• Canvas - shows what you have made in your timeline
• Viewer - your editing window
• Effects - transitions, filters, generators, etc.

9. Editing - Basics Cont.
Keep it short and sweet
• Limit shots to 3 - 10 seconds if possible
• Use only what tells the story, not just something pretty
• Keep the scenery/angle changing to keep interest
• Use music/other audio to help tell the story.
- Make sure it’s not too loud to overpower your speaker
-Use cross-fades to help audio remain smooth
• Use good B-roll and illustratives to visually tell the story.
- They can also help hide edits :)

10. COMPRESSION
Getting your file to the right size
http://techtv.mit.edu/

11. Compression - Basics
Why Compress/transcode?
What format?
• Quicktime (.mov)
• Windows Media (.wmv)
• AVI (.avi)
• Mobile (.mp4, .m4v, .ogg, etc.)
• DVD (Mpeg 2, AIFF)
• Flash (.flv)
Software:
• Quicktime Pro, On2, Mpeg Streamclip, Handbrake,
Compressor, Sorenson Squeeze, VLC, FFMpegX, etc.

12. Compression - Settings
What each setting means/does:
Video:
Compressor/codec: a specific set of algorithms that removes
data from your video to make it smaller. (ex. H.264)
Quality - just like it says
Frames - how many frames per second are shown. The less
the smaller the file and the choppier the video looks. (ex. 30fps)
Bitrate - amount of data per second of video. The lower the
smaller the file and the lower the quality of the picture image.
http://techtv.mit.edu/

13. Compression - Settings
Video continued:
Key Frames - how often you want a clear frame and one that
the web video can seek to, to show. The more spaced out,
the smaller the file, but the less accurate the seek online
(ex. every 150)
Screen Size - how large the final video looks. The smaller the
dimensions the smaller the file size, but too small can be
hard to see what’s happening (ex. 640 x 480)
*be sure to maintain your aspect ratio to prevent distortion
Interlaced v. Progressive
http://techtv.mit.edu/

14. Compression - Settings
Audio:
Format - similar to compressor/codec for video (ex. AAC)
Sample Rate - how many times a waveform is “sampled” to
in compression. The lower the rate, the smaller the file but
the lower the quality of the audio. (ex. 32.000 kHz)
Channels - mono, stereo, other surround sound. The more
channels, the larger the file size.
Bit Rate - how much data per second of audio. The lower
the rate, the smaller the file butthe lower the quality of the
audio. (ex. 48 kbps)

17. Hands-on / Q&A
http://techtv.mit.edu/

18. Homework
Pick a subject (something new to you on campus,
a person, a place, a thing, etc.)
Make a 1 - 2 minute summary video of your subject
• write your outline and scene shots
• get your footage
• compile your extras (graphics, music, other)
• digitize and log your footage
• start editing a rough cut if you’re up for it
