    3. Set the frame rate, e.g. 25 for South Africa (50 Hz power to prevent light flicker).
    4. Then set the default output dir

https://www.youtube.com/watch?v=n2m2uN9pH-w&list=PLjyuVPBuorqJb1AwUu-wh61cLWMBVWS3N&index=2

  • Each panel is a Editor Type. Can change any panel to a different panel type.
    • Not there are two types of Video sequencers, Sequencer and Preview.
  • Can make a copy of a panel by going to top left of the panel, should get a cross hair, then left click and drag. To reverse the process drag outward into another space to take that space (shows a carret).
  • Global hotkeys apply to the panel the mouse is currently over.
  • Hence be aware of where the cursor is when trying to use shortcuts.

3. IMPORTING

https://www.youtube.com/watch?v=zslAZxC29rk&list=PLjyuVPBuorqJb1AwUu-wh61cLWMBVWS3N&index=3

  • There are three ways to import media:
    1. From the OS drag and drop into the sequencer, will be placed at the playhead (blue line).
    2. Using the built in importer.
      • Has a filter to filter the types of files.
      • Can select the display type, e.g. list or thumbnails.
      • Big advantage is that is has a Recursion option, e.g. show 3 levels deep.
      • Click and drag from the center of the image/icon.
      • Only uses the framerate from the first import, then ignores every subsequent movie's frame rate that is added.
    3. At the top of sequencer, click Add then select Movie/Sound/Image
      1. Top right gear allows us to set default import settings.
      2. Can only add multiple movie via this method.
      3. When importing multiple movies, places them one after each other.

3. IMPORTING ISSUES

https://www.youtube.com/watch?v=n7qeKekS10E&list=PLjyuVPBuorqJb1AwUu-wh61cLWMBVWS3N&index=4

  • Goto Help -> Manual, on left nav click on Files & Data System -> Media Formats
  • Blender can't support variable framefrate movies. Use Handbrake to convert the movie before importing it into blender. Can install it with scoop install handbrake.
  • Encoders add an extra audio frame to their output. Can remove this frame:
    1. Select the audio strip
    2. Goto it's properties and expand Time, and set Hold offset end, and click right arrow to set it to one.

Video Sequence

https://www.youtube.com/watch?v=S6Ti9-eM5mw&list=PLjyuVPBuorqJb1AwUu-wh61cLWMBVWS3N&index=5

  • Can toggle sidebar options with "N"
  • Higher layers sit ontop, but layer 0 is special, and is the topmost layer.
  • Can select a video strip, then in the sequencer options change the blend/opacity.
  • If you select an audio strip, and check Display waveform.
  • Can move the playhead by clicking/dragging on the Time area (time + framerate bar at the top of the sequencer)
  • The orange knotches below the scrub area show the part of the video which are cached.
  • If right click on a video strip, can see it's meta data by going to the sidebar, expanding Source, and look at e.g. dimensions.
    • If you wish to change the projects resolution to match the strips resolution, RMB on the video strip, and select Movie Strip -> Set render size.
  • If goto preview, presss n, then select the View tab, then expand View Settings, the channel number shows from that number down. E.g. if you set it to 3, will show channels 3 down to 0.

CUTS & MOVING STRIPS

https://www.youtube.com/watch?v=qNrt0RFQCYY&list=PLjyuVPBuorqJb1AwUu-wh61cLWMBVWS3N&index=6

  • 3 Ways to cut
    1. Top tabs of video sequencer Strip -> Cut/Hold Cut
    2. K or SHIFT + K
    3. RMB to bring up the context menu and select Cut
  • Hold cut called so since it just keeps the frame the same. That's how one does a freeze frame in blender.
