Creating a video for FHD or UHD Players

This function requires an Advance License or higher. See also Licenses and functions.

This function allows simple creation of videos for the AV Stumpfl FHD or UHD Players. The videos are created using the H.264 codec for the FHD Player or, optionally, also using the H.265 codec for the UHD Player and are ideally suited for the AV Stumpfl Players in terms of their parameters.

Unless you have already done so, take the following preparatory steps:

• Optimize the display data  ...achieves better sharpness of the pictures and reduces the burden on the computer. See Optimizing display data for picture and text objects.

• Optimize the soundtrack level control  ...ensures lossless and correct audio playback. See Sound track peak level.

This is how you proceed:

1. Open your show. If you have just finished editing your project, save the modifications.

2. In the main menu, click Output - AV Stumpfl FHD Player ... and the corresponding dialog will appear.

3. For standard shows the default settings for Timeline, Screen and Display can remain as they are. You only need to choose the corresponding screens or timelines, when you are using several screens and timelines for your project. For multidisplay projects you can either select one individual display for output or All active displays, which allows creation of all videos for all active displays in one go. Option Display Splitting is used for distributed and simultaneous rendering via client computers and can only be used by specialist for very special applications.

4. Checkbox Fill output frame usually remains unchecked, to avoid distortion of screen or pictures. If the aspect ratio of the screen and of the video to be produced differ from each other, black borders are formed. To avoid black borders, check checkbox Fill Output Frame In this case the picture may be distorted as the full output format is forced.

5. For Multidisplay projects using a number of synced FHD Players, you can have the softedge mask additionally rendered into the picture. If applicable, place a checkmark next to this option.

6. Option Allow usage of intermediate video data can be enabled if you encounter problems, e.g. if videos cannot be rendered on the basis of original data. If the box is checkmarked intermediate video data are used for rendering provided the corresponding videos are available. See also Optimization through Intermediate Video Data.

7. Option Adjust display data manually should only be checked if you have important reasons to do so. It deactivates automatic creation of the corresponding display data for the chosen output size. A manual reduction of the display data size may, for instance, be necessary if there is not enough graphics memory for rendering the picture sequence and certain media cannot be displayed in the video.

8. The value for Black border can be left at 0 percent, as it is only required for older TV sets which do not allow deactivation of Overscan. Background information can be found at Border for playback on TV screens.

9. Select the portion to be rendered as video. The following options are available:

7. Complete timeline from 0:00 seconds ...just like the timeline, the video starts at zero seconds, so that a possible leader up to the first object is also included and finishes after the last object.

8. Complete timeline starting with first object ...the show starts before the first and finishes after the last object (recommended for standard videos).

9. Only selected portion of timeline ... the video will only contain the selected portion of the timeline. If no portion is highlighted this option cannot be selected. See Highlighting a portion

10. The target directory is your project folder, the preset filename is "Video 001". You can change these settings by clicking on and making the corresponding modifications. Following this, click Next.

Video

1. For Player model select the device you want to play your video with. Default output is H.264 video. For the UHD player you can optionally create an H.265 video. Check box H.265 for this purpose.

Note: Please note that H.265 can only be selected if your computer has an Nvidia graphics unit with Maxwell chips set or higher (i.e. GTX 9xx or Quadro Mxxx and up).

2. For Width/height enter the appropriate size of the video image. For Picture size note the following:

3. For the FHD Player the picture size is limited to 1920 x 1080 pixels. Use resolutions of 16:9 or 4:3, i.e. 1920 x 1080 pixels, 1280 x 720 pixels or 1024 x 768 pixels for example.

4. The maximum picture size for the UHD player must not exceed 3840 x 2160 pixels. Use resolutions with a ratio of 16:9 or 4:3, i.e. 3840 x 2160 pixels, 2560 x 1440 pixels, 1920 x 1080 pixels, 1280 x 720 pixels and 1600 x 1200 pixels or 1024 x 768 pixels, respectively.

5. For creation of split videos for Multidisplay Shows you click Assign standard screen output size to transfer the picture size. The picture size entered in the fields is larger than full HD but in case of splitting this does not matter as the video image size depends on the displays.

6. Pixel values must be an integer multiple of 4.

3. At Frames/s  click on and select the desired frame rate. 24, 25 or 30 frames/s can be selected. Higher frame rates are not supported by the FHD Player or are not played without any problems, respectively.

4. For Bitrate click also and select the required data rate. This affects the quality - the higher the bit rate, the better the quality.

5. If you want to create a control file for Speaker Support for the UHD player containing automatic stop information during playback check box Create control file for Speaker Support. If you want to create a control file without rendering a new video check box Create control file only (no video). The control file has the same name as the video but suffix *.ctl and is saved to the same folder as the video.

6. Click on Start to begin video rendering. This may take up to several hours, depending on picture size, show length and computer performance. Progress and cumulative speed at x-times real time are shown in the progress dialog.

Please note that powerful modern graphics cards can only process images and picture sequences up to a maximum width and height of 16,000 pixels. The limit for older graphics cards is 8,000 pixels. If an image is too large, it can’t be rendered and will not be included in the video.
