What is the Source Timeline and How do I Use it?

☕️ TL;DR - The Source Timeline allows you to view the currently selected Clip in the context of its Source Media.


Why do we use a Source Timeline? 

  1. When you are mixing together multiple videos, you have multiple Source Media files in your Project. It can be confusing when you see a particular Clip on your Timeline and you want to remember which Source Media that Clip comes from. By opening the Source Timeline, you can see the entire original Source video and where in that Source video your current Clip is from.
  2. Kamua does not support quick trimming from the beginning of a Clip on the Main Timeline (you can quick trim the end). The reason behind that is because it's currently not possible to have gaps in between Clips, and trimming the beginning would create a space. We plan to support gaps and full magnetic clip snapping in the near future.

Using the Source Timeline

Underneath the bottom left side of the video Preview area is the Source Timeline button Source-Timeline. Clicking this button will activate it. The Source Timeline always displays the Clip that is currently selected in the Timeline and from here you can:

  • Trim your Clips: This allows you to set where you want the Clip to start and end. Use the
    Startin pointand Endout pointbuttons on the Playhead to Trim the Clip from its current position. You can also drag the end and start of the Clip handles to a desired point. The new length of the Clip will be reflected on both the Source and Manual Timeline.

💡 Pro Tip: Use the keyboard shortcut (I) to create an in point and (O) for an outpoint from your Keyboard. Find out more about Shortcut keys open_in_new-24px in this article.

  • Trim Region: The Trim Region is the blue highlighted space on the Source Timeline and represents the current Clip. 
  • Split Clips: Use the scissor playhead-cut-scissors button on the Playhead or "C" on your keyboard to split the current Clip.
  • Find your KeyFrames: Your KeyFrames are represented as pink diamond icons inside the Trim region. Learn more about KeyFraming open_in_new-24px from this article. 

Important Note: If you wish to make your Clip longer, and you plan to resize the video (e.g. landscape to portrait) you should not expand the Trim Region to do so. Expanding the Trim Region will make it harder to achieve accurate cropping and resizing if you want to create a mobile video from your Project.

Remember, the Clip is on the Timeline and it has a Shot associated with it in the Shot List.

So, if you want to add more material before or after the current Clip, you should

  • go to the Shot List
  • find the Shots that come before and after the Shot from which you created the current Clip
  • add those Shots before and after the Clip on the Timeline
  • now that those Shots are Clips on the Timeline, you can edit them individually, instead of expanding the Trim Region of the first Clip.

If you don't plan on resizing the video for mobile (portrait/vertical, square, etc) then you can expand or lengthen the Clip in whatever way you wish.
