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.
