# The SequenceWindow

## Sequence Toolbar

### WindowType

As with every window header, the first button allows you to set the type of window.

### Full Window

Maximise the window, or return to the previous window display size; return to the previous screen setting (CTRL-UPARROW).

### Home

All visible Sequences are completely displayed, centered in the window (HOME).

### DisplayImage

The window shows the result of the Sequences, i.e. a picture.

### View Zoom

Move the mouse to zoom into or out of the SequenceWindow. This is an alternative for CTRL-MMB and MW. View Border (IconBut) Draw a rectangle to indicate what part of the SequenceWindow should be displayed in the full window.

### Clear

Force a clear of all buffered images in memory.

## SequenceWindow

In the SequenceWindow you arrange your scenes, external pictures or movie files for the postproduction of your animation. The Strip in row 1 is a sequence of numbered jpeg-pictures. It will play for a few seconds and then `SCENE 1` in row 2 will be superimposed with the `ALPHAOVER` effect in row 3. The `ALPHAOVER` generates some shadows, which can be seen in the film-strip below. In `SCENE 1` (which is a normal Blender-scene) the titeling is done with the usual animation features from Blender, which makes that system a very flexible titler.

In the end a transition of strip in row 1 and the folowing in row 2 is done with the `CROSS` effect. The numbers 1-2 are representing the row numbers the effect applies to. The result is a smooth fade between the two strips in row one and two.

## The mouse

### LMB

The position of the mouse cursor becomes the current frame. If DisplayImage is ON, the Sequences at this position are read or calculated at this position.

### MMB and drag

Depending on the position within the window:

- On the sliders; this can be moved.

- The rest of the window; the view is translated.

### CTRL-MMB and drag

Zoom in/out on the IpoWindow. For ease of use, you can only zoom horizontally. Use the HeaderButton if you must zoom vertically as well.

### RMB

Selection works the same way here as in the 3DWindow: normally a maximum of one Sequence strip is selected. Use SHIFT to extend or reduce the selection (extend select).

### RMB and drag

Selects something and immediately starts translation mode, i.e. the Grabber.

### SHIFT-RMB

Extend

selection.

## The hotkeys

### NUM+ , NUM-

Zoom in, zoom out.

### SHIFT-NUM+

Insert gap. One second is inserted at the current frame position. This only applies to strips that are totally to the right of the current frame.

### ALT-NUM+

Insert gap. As above, but now 10 seconds are inserted.

### SHIFT-NUM-

Remove gaps. All strips that are completely to the right of the current frame and do not start past the last frame are repositioned so that there is no longer an empty space.

### NUM.

The last selected strip is displayed completely.

### HOME

All visible Sequences are displayed completely, centered in the window.

### AKEY

Select All / deselect All. If any strip is selected, everything is first deselected.

### SHIFT-A

Add sequence. A PopupMenu asks you to make a choice. The first three are possible sources:

- "Images"; Specify with FileSelect (with RMB select!), what pictures will form a strip. If only 1 picture is selected, the strip is lengthened to 50 frames. Directories can also be specified; each directory then becomes a separate strip in the SequenceWindow.

- "Movie"; Specify with FileSelect (with LMB or RMB!) what movie will comprise a strip.

- "Audio"; Specify with FileSelect (with LMB or RMB!) what WAV file will comprise a strip.

- "Scene"; A PopupMenu asks you to specify the Scene that is to be inserted as a strip. The Scene is then rendered according to its own settings and processed in the Sequence system.

The following menu options are effects that work on pictures; two strips must be selected for this. The order of selection determines how the effects are applied.

- "Plugin"; a File Window let you choose a sequence plugin.

- "Cross"; a fluent transition from strip 1 to strip 2.

- "GammaCross"; This is a gamma-corrected cross. It provides a more 'natural' transition in which lighter parts are inserted before darker parts.

- "Add"; two strips are added together.

- "Sub"; the second strip is subtracted from the first.

- "Mul"; the strips are multiplied.

- "AlphaOver"; the second strip, with its alpha, is placed over the first. pictures with alpha are normally 32 bits.

- "AlphaUnder"; the first strip is placed behind the second, with the alpha of the second strip.

- "AlphaOverDrop"; like "AlphaOver", but now with a drop shadow.

### BKEY

Border select. Draw a rectangle with the LeftMouse; all strips that fall within this rectangle are selected. Draw a rectangle with the RightMouse to deselect.

### CKEY

If one of the ends of a strip is selected (the triangles), the current frame is moved to this end. In all other cases, the Change menu is invoked. This menu allows you to change specific characteristics of the active strip.

If this is an Image strip:

- "Change Images". The FileSelect appears and new pictures can be specified.

If this is an Effect strip:

- "Switch a-b"; change the sequence of the effect.

- "Recalculate"; force a recalculation of the effect.

- "Cross, Gammacross, Add, ..."; change the type of effect.

If this is a Scene strip:

- "Update Start and End"; the start and end frame of the Scene is processed in the strip again.

### ALT-D

Add Duplicate. All selected strips are copied. Immediately thereafter, translation mode is started. The images in an Image strip are reused; they take up no extra memory.

### FKEY

"Set Filter". An extra Y filter can only be activated in Movie strips. This filter is for a stable video display with no flickering.

### GKEY

Translation mode (the Grabber). This works on selected strips or the (triangular) ends of selected strips. Alternative for starting this mode: RMB and drag;. The following options are available in translation mode:

- Limitors: SHIFT with finer translation.

- MMB limits the current translation to the X or Y axis. Blender calculates which axis to use based on the already initiated mouse movement. Click MiddleMouse again to return to unlimited translation.

- ARROWS: These keys can be used to move the mouse cursor exactly 1 pixel.

- Grabber can be terminated with:

  - LMB SPACE or ENTER: move to the new position.

  - RMB or ESC: everything returns to the old position.

### MKEY

Make Meta. The selected strips are combined into a Meta strip. This only occurs if no unselected strips are linked to the selection by effects. Use TAB to view the contents of a Meta or to leave the Meta. Metas can be inside other Metas, and behave exactly like a normal Sequence strip. When Metas are duplicated, their contents are not linked!

### ALT-M

Un-Meta. The selected Meta is 'unpacked' again.

### SKEY

Snap menu. The PopupMenu offers you a choice: "Sequence to frame"; the selected strips are placed with their starting point on the current frame.

### XKEY

Delete Sequence. The selected strips are deleted.
