# The Replay Node

> **Deprecation Notice**
> This page describes features that have been removed or replaced in Luxonis Hub. Functionality may be limited and only available to Hub Original customers. Please refer to the up-to-date guides to provision devices, manage fleets, and deploy applications.

Use the `rh.ColorReplayCamera` node as a stand-in for the `dai.node.ColorCamera` node when you want to feed video files or image
sequences into your app instead of live camera input. Simply point it to a mp4 file or a folder full of .jpg images and it'll
handle the rest, piping those videos or images straight into your pipeline.

This is super handy for developing, testing, or tweaking your app with pre-recorded footage or snapshots. Plus, if you've got an
app running on Luxonis Hub, sending video events, you can loop those videos back in to refine, debug, or further test your app.

Currently, it supports `video`, `preview` and `out` outputs, covering the basics pretty well. The `video` output offers NV12
frames for encoding, `preview` feeds BGR or RGB frames ideal for neural network inputs, and `out` delivers RAW8 grayscale images,
just like you'd get from a `MonoCamera.out` output

```python
rgb_sensor = rh.ColorReplayCamera(pipeline=pipeline, fps=rh.CONFIGURATION["fps"], src="video.mp4", run_in_loop=True)
# when you have .jpg images stored in 'folder_with_jpg/' then you can
rgb_sensor = rh.ColorReplayCamera(pipeline=pipeline, fps=rh.CONFIGURATION["fps"], src="folder_with_jpg/", run_in_loop=True)
# create other pipeline nodes
rgb_sensor.video.link(h264_encoder.input)
rgb_sensor.preview.link(nn_node.input)
```

Substituting a `MonoCamera` node looks like this

```python
mono_sensor = rh.MonoReplayCamera(pipeline=pipeline, fps=rh.CONFIGURATION["fps"], src="video.mp4", run_in_loop=True)
mono_sensor_brg = pipeline.createImageManip()
mono_sensor_brg.setFrameType(dai.RawImgFrame.Type.BGR888p)
mono_sensor.out.link(mono_sensor_brg.inputImage)
# create other pipeline nodes
mono_sensor.out.link(h264_encoder.input)
mono_sensor_bgr.out.link(nn_node.input)
```
