The watermark will appear in upper right corner of your output display, during the playback of Video/CD+G clips. The watermark will relocate when a video with a different aspect ratio is played.

Note: The watermark will disappear automatically when playback is stopped, or the Slideshow is running.


Options -> Video/CD+G -> Watermark ->

Enabled: Enable/disable the watermark.

Visibility: Sets the transparency/visibility factor of the watermark.

Custom -> Use Custom If Available: If enabled, OtsAV will look in the C:\OtsLabs\VideoAssets\Watermark folder for custom Targa (TGA) files to use as the watermark (see below for specific information). If a compliant file can not be found, the Ots Labs watermark will be used instead.

Custom -> Apply Outline/Drop-Shadow (Recommended): If enabled, adds a drop-shadow to watermark making it more visible in varying underlying content conditions.



Customization of Watermark Instructions

Note: OtsAV TV Broadcaster allows full watermark customization without any co-branding. Other OtsAV video products also allow watermark customization, however, with the co-branding component of the OtsAV splash logo which will very briefly sweep across the screen after a video transition has occurred (it is normally suppressed for shorter items).

C:\OtsLabs\VideoAssets\Watermark is the folder where you may place image files to be used by the OtsAV video subsystem as part of the custom watermark feature.

Files *must* be in the Targa format (ending with .tga) and must be full 32-bit with a transparency/alpha channel. You can use an image editor like Photoshop or Gimp to create such files. Also have a look at the sample files already in C:\OtsLabs\VideoAssets\Watermark

Note: When saving the file in Gimp or other software, it is important the RLE compression is disabled as the Targa files must be in uncompressed form to be compliant with OtsAV. In Gimp, Save A Copy will always present the RLE compression choice before saving.

OtsAV supports multiple internal resolutions and a different file will be chosen depending on the current resolution in use by the application.

You only need to create files for the resolutions you plan to use. If a specific file is not found or is non-compliant, OtsAV will fallback to using the Ots Labs watermark.

* means you can actually go one pixel higher than this if necessary (the true maximum), however the ideal "maximum" rounds to the value shown.

Note #1: Not all resolutions are supported by all products.

Note #2: The sizes listed above are maximum sizes only. You can (and in many cases should) create image files smaller than the maximum sizes shown here.

Note #3: It is strongly recommended you keep a master copy of your Targa files elsewhere than the working folder as it is possible re-installing the software could copy over your files by default if your files are dated older than a given installation.


Tip: The Options -> Video/CD+G menu can also be accessed by right-clicking your mouse on the middle video display (when visible). This is the suggested method, as it is the quickest way to access the Video/CD+G features.
