Video Editing Tutorials
Summary of important Technical Information for Video
- Video is made up of a sequence individual images that when played in create the "illusion of motion"
- Each still images is based on pixels - raster graphics - limit scaling
- Resolution of the video frame - 1920 x 1080 pixels for "Full High Definition" video - there are other resolutions. ie. 4k video
- Video historically works in a frame rate of 30 frames per second - expressed as fps - film typically uses 24 fps
- 30 frames of video = 1 sec in time when working in 30 fps
- 15 frames = 1/2 sec. 60 frames = 2 sec.
- "Timecode" counts the frames of a video clip and the length of the video on the timeline
- 00:00:00;00 = hrs. mins. secs. frames
- at 29 frames the timecode rolls over to the next second
- Duration of a clip on the timeline tells how long that clips is in secs and frames - useful information when adding images
Trimming Video Clips on Timeline
Shotcut but principles are the same for all video editing software programs
Shotcut but principles are the same for all video editing software programs
Key Concepts - applies to all video editing software - location of buttons will vary
- Importing Files to project
- Adding an image to the project - Large size
- Adding clips to the timeline
- Trimming clips
- In point/Out points
- Trim by dragging on Timeline
- Trim by splitting clip on timeline
Editing a Sequence in "Realtime"
Editing to Compress Time
During your editing assignments you will be "compressing time" at certain points in the video
What does "Compressing Time" mean?
Compressing time achieves a couple of things
1. Leave out all the boring or uneventful parts of a video
2. Advances the story much more quickly to hold the interest of the audience - the most important reason
Look at the scene you are editing, are there portions of the characters travel through the scene that aren't included? Does the scene take less time to happen that it would in real time?
Imagine watching a person walk to school It might take them 15 mins. to do so. Would that be exciting to watch? Not really, we only want to see the highlights of the walk along the way. We can compress time for the somewhat uneventful 15 mins. walk to perhaps 30 secs. and include anything interesting or exciting along the way. We cut out the bring non-eventful walk.
That's what compressing time in editing does. It moves the story along without having to show us every single step along the way.
Below is an excellent video that demonstrate the concept of "compressing time" in a film or video. By doing so the attention of the viewer is maintained and only the relevant actions/activities are shown. As a viewer we have become accustom to compressing time and still believe the scene we are watching without question how the character or activities have progressed.

Compressing Time Example
Drew Kellar of Story Guide
He demonstrates the value and technique of compressing time in a video edit. Notice how the first half of the scene is in "real-time." As he enters the house we see every second of him approaching the house, finding the key and entering the house.
Once in the kitchen to make breakfast the concept of compressing time is explained.

Audio Adjustments for Gym Class Hero in Shotcut
Let's talk audio
Audio Technical Specifications
Sound is important!
Sound tells half the story
Listen to these 2 clips - the sound completely changes the story:

Audio edits will expose poor edits as much as video
Technical tools (audio meter) help set "levels"
Your ears will make the ultimate decision to decide if audio in a scene sounds natural
This is called audio mixing - realistic balance of audio between voice, background sound and music.
Technical facts:
Units of measure for audio is the “Decibel” - written as db Example “0db” “-3db”
All audio levels must stay below "0db so the level is a negative number
“0 db” is at the top of an audio meter - highest level for any audio source
Audio that exceeds 0db goes into “distortion”
Distortion is buzzy or unclear audio because the level is too high
Audio shows as an “audio waveform” on the clips of the edit timeline
The higher the audio appears on the clips waveform on a clip the louder the sound
Audio Mixing Process:
Audio mixing is a craft and a technical skill - Academy awards are presented for audio design and mixing!
Many jobs in video production involve just the sound mixing of a video edit

Called “Natural Sound” - or “Nat. Snd.”
The Nat. Snd. is usually heard much lower than voice levels
Typically in the range from -10db to -20db - depending on the sound
5. Music must compliment voices NOT compete with voices
Music must be heard in the background “under” voices and mix well natural sounds of clips

- All audio levels with vary over a clip - be louder in some points and quieter in others
- The loudest points of the audio is called the “peak audio level” for that clip
- Always set voice audio levels first:
- Include all natural background clip sound
