My notes

Initial Setup

Properties Section

• Start Blender
• Select View layout to Video Editing
• If you see graph Editor, replace it with Properties window (with "drop-up button")

Properties

Dimensions

• Change the preset to your format, e.g. HDTV 720
• Check the Resolution
• Check the Frame rate. E..g. 30fps for youtube (should match the source video).

Output

• Check the location of the output file
• Set File format (e.g. H.264 or Xvid)
• Select RGB (for color)

Encoding

• Set preset to the same video format
• Bitrate: 6000 is ok
• Select Audio Codec (e.g. AAC or MP3)

Timeline Section

Playback menu:

• + Audio Scrubbing
• + AV Sync
• + Frame dropping

Save as defaults

• Menu -> File -> Save Startup File

System settings

Open: Menu -> File -> User Preferences -> System

• Sequencer / Clip Editor:
  • Prefetch frames: 500 (later versions may not have this setting any more)
  • Memory Cache limit - set to reasonable memory size in gigs: e.g. 10G out of 16G total RAM

Sequencer

• Right click selects a stream
• Box select: Press B, then draw a rectangle over the target strips

• Add media: Sequencer Menu -> Add -> Movie...
  • Make sure the frame rate matches.
  • To match the size for the whole movie, select the strip, then go to Sequencer-Menu -> Strip -> Set Render Size

Meta Strips

Make meta strip:

1. Select multiple target strips (with box select)
2. [Ctrl+G] Sequencer-Menu -> Strip -> Make Meta Strip
