Video Opacity Adjustment
Reading time ~2 minutes
The video track opacity can be adjusted by adding and manipulating the keyframes (KF) using the rubber banding Timeline feature.
Note
|
The objects added to the V1 video track are always non-transparent, so video opacity adjustment is not available within the V1 track. |
By default, all V1 video tracks are with disabled "Alpha transparency" mode. The corresponding information is displayed in the context menu while right-clicking the V1 track name:
For other video tracks the "Alpha transparency" mode is disabled by default.
To enable "Alpha transparency" mode for a video track, right-click the required track name and selected the "Alpha transparency" option from the context menu:
If the "Alpha transparency" is enabled, the corresponding "AT" icon will be displayed next to the track name, allowing to work with video opacity rubber banding:
If you drag-and-drop a Titler template or an image into a regular track without "Alpha transparency" mode enabled, the following message appears:
The following options are available:

|
