Clip Extractor Fixed Length Clips

Fixed-Length Clips

Use this when every clip should be the same length, for example a series of 5-second segments. Instead of marking In and Out, you set a length and slide a box along the timeline.

Press L (or the Fixed length button) to turn it on.

Setting the length

Type the length in either box:

• Seconds, down to hundredths (for example 4.46).
• Frames (for example 107).

The other box updates to match. Whichever you typed last is the one that is exported exactly. A length longer than the video is clamped to the video.

The selection box

A red box on the timeline shows the selected clip.

• Drag the box to move the clip.
• Click outside the box to jump the clip start to that spot.
• Click inside the box to move the playhead within the clip.
• Shift+drag scrubs without moving the box.

Playback stays inside the clip

While fixed length is on, Play, frame stepping, keyframe jumps, Home and End all stay inside the selection and stop at its last frame. Pressing Play at the end starts again from the clip start.

The Move clip row

A row of buttons appears that mirrors the playback buttons, but moves the selection box instead of the playhead:

Button	Key	Effect
Start	Ctrl+Home	Move clip to the start of the video
◀K	Ctrl+Shift+Left	Clip start to the previous keyframe
◀	Ctrl+Left	Move back one frame
▶	Ctrl+Right	Move forward one frame
K▶	Ctrl+Shift+Right	Clip start to the next keyframe
End	Ctrl+End	Move clip to the end of the video
Start at playhead	I	Clip starts at the frame you are looking at
Next clip	N	Clip starts on the first frame the current clip does not include
Playhead to clip start	Home	Jump the playhead back to the clip start

Mark In moves the clip to start at the current frame; Mark Out moves it to end just before the current frame.

Cutting a whole video into equal clips

1. Set the length and press L.
2. Move the box to the start and press Ctrl+Shift+E (Quick export).
3. Press N to move to the next clip, then export again.

Next clip uses the true frame count of the clip, so consecutive exports line up with no overlap and no gap. When there is no room for another full clip, it moves to the end of the video and says so in the status bar.

Exporting and lossless

Export and Quick export use the selection. Lossless is still offered when both ends happen to land on keyframes and no crop, flip or colour match is active; otherwise the clip is re-encoded. Crop works at the same time. See Exporting.

Turning fixed length off restores your In/Out marks.

Defaults

The starting length and unit are set in Settings > Preferences > Crop & clip. See Preferences and Themes.
