Exporting

Use File > Export to export a sequence of images to disk. The export dialog will save all Save image nodes, so make sure you have those in your network.

tip

Exporting will not work if you don't have any Save Image nodes in your network.

Frame rate​

Because input nodes can have different settings, we set a frame rate to give an indication of the speed at which to export. As an example, exporting 60 frames at a frame rate of 30fps would export a 2 second sequence. The frame rate is important for real-time nodes like webcam, because it will try to capture that many frames per second, if it can.

Options​

Export takes a number of options:

  • Node The node to export. Defaults to the Out node.
  • Frames The amount of frames to export.
  • Frame rate The frame rate to export, e.g. exporting 60 frames at a frame rate of 30fps would export a 2 second sequence.
  • Folder The folder to export to
  • Prefix The file prefix. Files will have this prefix and then a number, e.g. a prefix of hands will have files called hands-0001.png etc.
  • Image Format Choose between PNG and JPEG here. PNGs are lossless, JPEGs are smaller but with a reduced quality. For machine learning we often use JPEGs with a quality setting of 90.
