Presenting videos

For very complex shows in particular, a mixdown of all media into a video is the only chance to present  at high quality without any problems. For this purpose, Wings Vioso RX offers powerful functions, which require the Advanced License or higher:

• Wings Vioso RX offers Exclusive Mode for video tracks. Exclusive mode ensures that all other tracks containing visual contents are temporary disabled. The track remains unconsidered during scrolling and playback in Preview Mode. Due to the extensive usage of hardware rendering via 3D graphics card this requires an up-to-date, middle-class graphics card. Exclusive Mode can be enabled in the Video Track Properties.

• Simultaneous, synchronized playback of multi-channel soundtracks from the timeline (via the Pro License). See also Multi-channel sound.

• Position markers and triggers allow navigation within the show without any windows or buttons being visible to the audience. See workshop Optimum show presentation.

• Playback stops automatically at stop markers and is continued after pressing a button, e.g. for Speaker Support. The show can be continued both via the keyboard or the mouse and via a remote control unit connected to a serial computer port.

• Variables and triggers control the alpha value of track groups and allow spontaneous dissolves from one video to another during the presentation (requires the Pro License). See Controlling track contents via triggers.

• In the event of a power failure or a system crash during the presentation, playback can automatically be resumed from the position where it stopped. See Power failure.

• All the actions programmed in the timeline for lights, switches and other devices are controlled and synchronized via the device ports.

Creating a multidisplay video presentation (sample project)

Starting / stopping playback

1. Create a video file for your project. ...See Methods for creating a video. For video creation select option Insert as presentation into the current project under Further actions. Following this a Video Track in Exclusive Mode containing the appropriate video is added to the timeline.

2. Using the mouse, move the Locator to the position in time playing back of your show is to start.

3. In the main menu, click on Presentation and select the type of playback by clicking either Start in fullscreen mode or Start in window.

The Presentation Mode can only be terminated by pressing the Esc key twice or by hitting Shift + Esc!

4. Playback is now in Pause Mode. Press the space bar to start playback from the Locator position. In Fullscreen Mode playback can only be controlled via keys/key combinations. Make sure you remember them!

Fullscreen mode   F5

Play / Pause Space bar (fullscreen remains)

Continue playback   Enter or space bar (fullscreen remains)

Stop   Press Esc once (fullscreen remains)

Terminate Press Esc twice (Wings Vioso RX reappears)

• As the soundtrack is played back from the timeline during the presentation, video file and sound track must be placed synchronously ... See also  Aligning objects. Moreover, the video files should also be available on hard disk. This is the only way to ensure that pictures and sound are played back synchronously.

• Presentation of a show can be started from a position marker. But it is also possible to jump to the previous or next marker. See Playback from position marker.

• Playback of a presentation stops automatically 10 seconds after the last active object.

• If the video is not played from its very beginning, it may take a few moments – depending on the number of keyframes – until the correct position is found. For DivX-videos, for example, with a keyframe interval of 300 frames and a frame rate of 25 frames per second, there is only one keyframe every 12 seconds available, which makes starting in certain locations difficult. When recalculating the video, you can choose a different setting for the keyframe interval ... See also Tips for video rendering.

• High-resolution videos with fast moving picture elements make high demands on the data projector signal processing system. For production you should use a tube monitor for reference purposes. Being an analog device it is able to display the video signals virtually without any delay – which is not true for LCD monitors. This is the only way to find out whether what you have produced with Wings Vioso RX is played without any jerks on your computer. See also Valuable information about data projectors and PC optimization.

• If the video is to fade in from darkness, you need to provide for a black leader when creating your video.

• During the period the video is presented Wings Vioso RX will disable screen saver and energy saving mode, provided they are enabled.

• By defining a password, a project can be protected against unauthorized editing and saving, as well as closing of the Control Panel. This is particularly important for permanent installations and presentation with touch panels. See Password protection.

Speaker Support Presentation

1. Place Pause markers at the positions in the show where playback is to stop automatically. ...This is how you set markers.

2. Upon starting Presentation Mode using F5 and playback using the space bar, the video will stop at the pause markers. To continue playback press one of the following keys:

3. Space bar

4. Enter key

5. Left mouse button

6. Play key on the Speaker Support remote control unit

3. Presentation Mode can be terminated any time by pressing the Esc key twice.

• According to the playback mode pressing the space bar causes either Play or Pause. Therefore, pressing the space bar too early may cause playback to be stopped prematurely.

• A professional way of controlling your show is via a Speaker Support remote control unit connected to a serial computer port. This, however, requires the port to be previously selected in the Media Pool under Devices.

• Use the Tascam US 224 for comfortably remote-controlling various playback functions. This device is also a high-quality audio interface, which allows connection of a microphone. It is therefore the ideal supplement to notebooks in particular. ... See also Remote control via Tascam US224.

• An alternative would be to use a good wireless radio mouse with the corresponding range as a remote control unit.

• For presentations in permanent installations, warning messages can be suppressed as they would interfere with the presentation. See Enabling/disabling all warnings.

• Videos with an aspect ratio that differs from that of a monitor or a projector can be moved from the monitor centre to the sides when presenting them. This function is actually an extended shift function for projectors. See Project Options – Presentation.

Continuing a video presentation after power failure

A power failure during the video presentation is the nightmare of every presenter. Wings Vioso RX can't prevent the power failure itself, but it allows the presentation to be continued from the point of interruption.

1. When the video presentation was aborted by a computer crash or a power failure, restart your computer.

2. Start up Wings Vioso RX. When starting up will be queried whether you want to continue the aborted presentation. Click Yes to load the project. Following this the video is started in Fullscreen Mode at the location where it was aborted.
