Inserting Images Over the Video in Real Time

You are here:
Estimated reading time: 2 min

Unlike the web interface of your encoders, BoraGrid allows you to insert images over the video at any time during your transmission.

Notes

  • The size of the image cannot be higher than the video resolution; otherwise, an error will occur.
  • The image file must be in PNG or BMP format. More recent versions of the encoder also accept the TGA format.
    • Give preference to the PNG format which is more modern and generates smaller files than the other two.
  • In the web interface of your encoders, in the event configuration tab, the “Image Inserter” option must be “ON” and the “Enable REST Control” option must be checked.
Image Inserter and Enable REST Control options in the encoder events settings.

Creating a list of images

In Boragrid you can enter the data for all the images you intend to use.

Go to Settings page then select the Images item.

Tip: Double clicking on an image entry in the list will open the image editing window.
