Frame Track

---

This track like interface represents the total length of a scene in frames. It's a dual purposed reference bar for both scene navigation and object composition. In navigation mode the interface of the track is materialized as a Frame Slider. In object mode the Slider changes itself into 2 arrow shaped In/Out Marks. The interfaces switch contextually depending on your composition activity.

Frame Slider (Navigation Mode)

The Frame Slider is basically a 'scrubber' for you to move through the internal frames of a scene on a track. When you drag it along the track (right or left) you can see the screen pictures (along with soundtracks) changed with your movement. The Frame Counter is also dynamically reflecting your current scrub position at all time. You can use this Slider to quickly glance through a scene and/or to locate a particular frame in that scene.

In/Out marks (Object Mode)

When an object is dropped onto the Compose stage or is being selected (with bounding box around it), the Frame Slider interface will change to become 2 arrow marks in the track. These marks represent the frame space of a scene occupied by the selected object. The left arrow denotes the 'IN' frame position of the object and the right one denotes the 'OUT' frame position of the object. When an object is first dropped onto stage, the IN frame is default to the current slider position of the scene and the OUT frame is default to the last frame of the scene. For instance, if the total length of a scene is 60 frames and the current slider position is at Frame 26 (with its picture showing on screen), a dropped-in object will occupy a frame space from 26 to 60 (which is 35 frames long). Of course, as in most cases, if the slider is at the beginning of the scene, a dropped-in object will occupy the frame space of the entire scene.

Click and select an object already on stage, the 'in' and 'out' marks show up indicating the corresponding frame space it occupies in the given scene. Click on either mark will bring you to the frame where the mark denotes and the Frame Counter will display frame number accordingly.

To adjust the on-stage duration of an object's, you select either mark (IN or OUT), then drag it left or right to the desired track position (frame). A selected mark is in orange color and an unselected mark is in gray color. Adjusting an object's property (position, size, color and etc.) from any frame within its occupied space will affect the the whole course appearance of this object in the scene.
