BEFORE YOU START

Before you start

Prepare a video you can use. Decide whether it fills the background or appears beside other material.

Screenshots show actual sample projects. Your interface may vary with your plan and updates. Instructions describe desktop browser operation; this guide can also be read on a phone.

STEP01

Import and add a video

Import the file through Add media → My media, choose it under Video and add it. You can also use a suitable preset video. Select the new video clip on the timeline to inspect its settings.

  1. Action Open My media
  2. Action Upload your file
  3. Action Select video, then Add
A selected video in My media. Uploading and adding it to the timeline are separate actions. The product screenshot is in Japanese; the instructions explain the controls.
STEP02

Choose full-frame or free placement

Use Fill frame for a background. It preserves the source ratio while filling the canvas, so mismatched ratios crop edges. Use free placement to preserve a product or text in full, then fill spare space with a background.

  1. Action Fill the frame
  2. Enter Free position and scale
Video placement controls for fill frame and free position and scale. The product screenshot is in Japanese; the instructions explain the controls.
Check faces and text
Filling the frame does not mean the entire source is visible. Check all four edges.
Layering
If the video hides a presenter or caption, check layer order and placement.
STEP03

Set source in and out

Open Video source range in Properties. The example uses source seconds 1 through 5, a four-second range. Leave Out empty to use the source ending. Changing this range is separate from changing the clip’s timeline duration.

  1. Enter Source in and out
Video source range. Source in/out and the clip’s time on the timeline are separate. The product screenshot is in Japanese; the instructions explain the controls.
STEP04

Combine timeline duration with looping

A four-second source range does not itself set the screen duration. For an eight-second repeating background, combine Normal loop with an eight-second timeline clip. Ping-pong alternates forward and backward playback; check that people or action do not look unnatural.

  1. Enter Loop and speed
Video source range. Source in/out and the clip’s time on the timeline are separate. The product screenshot is in Japanese; the instructions explain the controls.
No loop
Choose this when an action should play once, and adjust the clip duration to fit.
Playback speed
1 is normal speed. Review motion and duration after changing it. For video with audio, also check at normal speed rather than judging audio solely from speed-adjusted preview.
STEP05

Hold the ending frame for an explanation

Choose Place end frame after under Add still frames. The ending frame of the selected source range becomes a separate image clip after the video. In this example, a two-second image clip was added; adjust it to fit the explanation. Leave space before or after the video if there is no room for the still. Place start frame before is useful for explaining before playback begins.

  1. Action Add a still frame
Video source range. Source in/out and the clip’s time on the timeline are separate. The product screenshot is in Japanese; the instructions explain the controls.
STEP06

Review the transitions and the MP4

Play the entry, loop boundary and transition to a still, not just the middle. Check picture continuity, audio and caption overlap, then generate any required avatar clips and review the exported MP4.

  1. Action Click near the beginning of the ruler.
  2. Action Click the triangular Play button.
  3. Check Check Saved.
The generated preview. Play it to review the avatar and speech. The product screenshot is in Japanese; the instructions explain the controls.

BEFORE YOU FINISH

One final check.

Check source time versus project time, fill-frame cropping, loops and still-frame duration.
