File > Export to export a sequence of images to disk. The export dialog will choose the Out node by default.
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.
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
handswill have files called
- 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.
