Overlap Mode defines the result of transforming a strip so that it overlaps another strip.
The overlapping strip will be moved to the nearest free space so that it does not overlap.
The overlapped strip will be overwritten, trimmed or split by the overlapping strip.
All strips on the right side of (each) transformed will be shifted forward to accommodate the overlapping strip.
It is possible to enable snapping in the header of the VSE. The snapping behavior can be configured as follows:
- Snap to
- Current Frame
Snaps the transformed selection to the Playhead.
- Hold Offset
Snaps the transformed selection to the Hold Offset.
- Muted Strips
Muted Strips are not considered as snap targets.
- Sound Strips
Sound Strips are not considered as snap targets.
- Current Frame
- Snap to Strips
Snaps the Playhead to all strips.
Pressing G moves all the selected strip(s). Move your mouse horizontally (left/right) to change the strip’s position in time. Move vertically (up/down) to change channels.
Holding down Ctrl while dragging enables or disables snapping.
You can also lock the direction to time with X or to change the strip’s channel with Y.
It is possible to move strips using mouse by dragging them while holding LMB. Currently it is possible to move only one strip by dragging.
Start Frame Offset
The Start Frame Offset for that strip can be selected by clicking LMB on the left handle of the strip; holding it down (or pressing G and then moving the mouse left/right) changes the start frame within the strip by the number of frames you move it. The frame number label under the strip displays the start frame of the strip.
If you have a 20-image sequence strip, and drag the left handle to the right by 10 frames, the strip will start at image 11 (images 1 to 10 will be skipped). Use this to clip off a roll-up or undesired lead-in.
Dragging the left handle left will create a lead-in (copies) of the first frame for as many frames as you drag it. Use this when you want some frames for a transition at the start of the clip.
The End Frame of the strip could be selected by clicking LMB on the right handle of the strip; holding it down (or pressing G) and then moving the mouse changes the ending frame within the strip. The frame number label over the strip displays the end frame of the strip.
Dragging the right handle to the left shortens the clip; any original images at the tail are ignored. Use this to quickly clip off a roll-down.
Dragging the right handle to the right extends the clip. For movies and images sequences, more of the animation is used until exhausted. Extending a clip beyond its length will render as a copy of the last image. Use this for transitions out of this clip.
You can select several (handles of) strips by Shift-LMB clicking: when you press G, everything that is selected will move with your mouse – this means that, for example, you can at the same time move a strip, shorten two others, and extend a forth one.
Move/Extend from Current Frame
With a number of strips selected, pressing E lets you interactively extend the strips. This is similar to moving but is useful for extending (or shortening) time around the current frame.
All selected strip handles to the «mouse side» of the current frame indicator will transform together, so you can change the duration of strips at the current frame.
Extend is a convenient way to adjust the time of rough edits such as an «animatic» (sequential storyboards). Where it’s possible to select everything and adjust the length of strips around the current frame. This can be especially useful when adding in audio or other elements that could cause the timing to need adjustment.
When performing this operation you may want to enableso markers are updated too.
This simply a convenience operation, instead of manually selecting strips on one side of the current frame, as well as handles on one side of overlapping strips. Then selecting and transforming markers as well. This avoids the manual process, so re-timing can be accessed quickly.
Slip Strip Contents
The Slip tool allows you to change the position of the contents of a strip without moving the strip itself.
Snap Strips to the Current Frame
Moves the strip or control point to the current frame.
Clear Strips Offset
To reset the (soft) start/end frame handles.
- Left Alt-Left
Swaps the active strip with the strip to the left.
- Right Alt-Right
Swaps the active strip with the strip to the right.
Remove blank frames between the current frame and the first strip to the left, independent of selection or locked state of strips.
- All Gaps
Remove gaps to the right of the strip along with the left.
Insert blank frames between the current frame and the first strips to the right, independent of selection or locked state of strips.
Scale to Fit
Adjusts the strips Scale Transforms so the visual contents of the strip to fit exactly within the project’s Resolution while maintaining the original aspect ratio.
This may mean that the transparent areas may be added along the content’s border to fit the content in the rendered area.
Scale to Fill
Adjusts the strips Scale Transforms so the visual contents of the strip to span the project’s Resolution while maintaining the original aspect ratio.
This may mean that portions of the original image no longer fit the content inside the rendered area.
Stretch to Fill
Adjusts the strips Scale Transforms so the visual contents of the strip to fill the project’s Resolution. Note, unlike the other two methods described above, Stretch to Fill does not maintaining the original aspect ratio.
This may mean that the original image becomes distorted to fit the content inside the rendered area.
Resets the strips Position Transforms to a value of zero.
Resets the strips Scale Transforms to a value of one.
Resets the strips Rotation Transform to a value of zero.
Resets the strips position, scale, and rotation Transforms to their default values.
This splits the selected strip in two at the current frame. This will result in two strips which use the same source, fitting the original strip’s timing and length.
This can be thought of as a quick way to duplicate the current strip, adjusting the start/end frames to form two non-overlapping strips showing the same content as before.
Like Split, it splits a strip in two distinct strips; however you will not be able to drag the endpoints to show the frames past the split of each resulting strip.
Although you can adjust the Hold Offset number fields in the Strip Info panel.
This can be thought of as a way to simulate splitting the video file in two parts at the cut-point, replacing the current strip with each.
Duplicate a strip to make an unlinked copy; drag it to a time and channel, and drop it by LMB click.
Delete the selected strip(s).
Update Scene Frame Range
For Scene strips only – Updates the strip’s Time properties to match the referenced scene’s frame range. This operator should be used when the referenced scene’s length is extended or shortened.
For images sequence only – Converts the strip into multiple strips, one strip for each frame. Useful for slide shows and other cases where you want to bring in a set on non-continuous images.
You have to specify the duration you want the resulting strips will be.
Set Render Size
Sets the render resolution and aspect to match the strip’s resolution.
Converts interlaced video into progressive video.
Change Effect Input
Swaps which strips are the input for the effect strip.
Change Effect Type
Switch the effects on a selected Effect strip.
This tool can be used to assign (reconnect) effect strips in a different way. Select three arbitrary strips and press R. If you don’t create a cycle, those will be connected to a new effect chain.
Swaps the first two inputs for the effect strip.
- Lock Strips Shift-L
Disables the strip from being transformed.
- Unlock Strips Shift-Alt-L
Enables disabled strips allowing them to be transformed.
- Mute/Unmute Strips H, Alt-H
Mute or unmute the selected strips.
- Mute/Unmute Deselected Strips Shift-H, Ctrl-Alt-H
Mute or unmute all strips but the selected.
- Reload Strips Alt-R
Reloads the strips from their external saved location.
- Reload Strips and Adjust Length Shift-Alt-R
Reloads the strips from their external saved location and re-adjusts the strip duration.
- Change Path/Files
Changes the source file contained in a selected strip.
- Swap Data
Swaps two sequence strips.
This submenu contains tools to add or remove fades to strips. In case of visual strips the tools will animate the opacity or volume in case of audio strips.
- Clear Fades
Removes fade animation from selected sequences.
- Fade In and Out
Fade selected strips in and out.
- Fade In
Fade in selected strips.
- Fade Out
Fade out selected strips.
- From Current Frame
Fade from the current frame to the end of overlapping sequences.
- To Current Frame
Fade from the start of sequences under the Playhead to the current frame.
Strips can be sped up or, slowed down using retiming tool. When tool is activated, retiming controls can be used on active strip.
Retiming tool will not work with effect strips.
Adding Retiming Handles
When tool is activated, retiming handle is added at the end of the strip. This handle is not visible, but can be moved in a way similar to resizing the strip. Retiming handles are added by clicking on + button displayed on the strip next to current frame. This button is only visible when current frame intersects the strip.
Moving Retiming Handles
Retiming handle can be moved by dragging it with mouse. The handle is mapped to particular frame of strip content, so moving handle effectively means moving a frame to new position. When handle is moved, all remaining handles to the right will be moved by same amount. Handels can not be moved past each other or start of the strip.
Only strip content is retimed, existing animation is not handled by the tool
Removing Retiming Handles
Handle can be deleted by clicking on triangle. When handle is deleted, strip size will not change and speed will change to average between 2 affected sections.
Retiming split strips
When strip is split, retming handle is created on both strip edges. If split happens on frame where there already is retiming handle, it is reused, so existing retiming is not affected. These retiming handles will be invisible and handle on left strip edge can not be moved.
