Video editor enables to work with different objects, namely: "Sprite", "Duplicate", "Line", "Rectangle", "Ellipse", "Tooltip", "Image", "Sound", "Video", "Movement" and also with a large quantity of video and audio effects.

You can add these objects using the same methods which are divided into three stages: choice of object, setting up its position in time and on the scene. For more information about the first and the third stages see example of adding video and image to the scene in section "How to open video file or image for editing".  In the present section we shall explain how to set object when it is added to the scene.

When you add object to the scene or when you apply effect to object you see the following window which sets object/effect position in time:

In this window you may set time of object appearance to the scene (effect start time), duration of display (effect duration), as well as its dynamics upon change of parent object duration. Let’s review in details each parameter:

• By work area – sets time of appearance and duration as per the marked working area on timeline (duration of video and audio objects is set not according to working area duration, but in accordance with duration of video and audio material in a file).
  

  

• From cursor position - sets time of appearance starting from cursor position on timeline and automatically sets duration to the end of the scene (duration of video and audio objects is set not to the end of the scene but according to video and audio material in a file).
• To cursor position  – sets time of appearance starting from beginning of parent object (scene or sprite) to cursor position on timeline (duration of video and audio objects is set not to cursor position but according to video and audio material in a file).
• Whole parent duration - sets time of object appearance and its duration equal to parent object duration. Connection of object duration with parent object duration is also set ("Lock end position").
• From scene begin - sets time of appearance starting from parent object. Object duration is manually set (except for video and audio objects which have duration set according to duration of material).
• To scene end - sets time of object disappearance equal to time of parent object disappearance. Duration is manually set. Connection of object appearance time and its duration with parent object duration are also set ("Lock start position  and "Lock end position").
• From manual position – time of object appearance and its duration are manually set.
• To manual position – time of object disappearance and its duration are manually set.
• Lock start position  - sets connection of object appearance time with parent object duration, i.e. if parent object duration is changed object appearance time will be automatically recalculated.
• Lock end position -  sets connection of object duration with parent object duration, i.e. if parent object duration is changed object duration will be automatically recalculated.

We recommend to choose "Whole parent duration" option for filters and other effects covering the whole duration of parent object, because in this case "Lock end position" option is set and when object duration is changed, effect duration will be automatically changed.

At the same time for transition effects we recommend to choose "From scene begin" or "To scene end". In such case options "Lock start position" and "Lock end position" are set the way that when object duration is changed, duration of effect will not be changed, and effect finish time will always coincide with time of object disappearance if you choose option "To scene end".
