Hi @monajalal The master branch of the rosbag2video repository now states support for Humble. |

@MartyG-RealSense have it recorded it wrongly? I only have a These were my steps (please correct me if wrong -- I am new to ros2) You should do these steps after successfully installing realsense-viewer and being able to run it to make sure you have an RGB feed from your camera. After step 3, you should see something like the following in RVIZ.
^^^ actually I am only interested in depth align depth along with RGB bags (no other bags) similar to NVlabs/BundleSDF#82 (comment) Please let me know if further info may be needed. |

You do not need to launch with ros2 run and ros2 launch in separate terminals. One or the other methods should be used but not both at the same time. I would recommend testing with the ros2 launch command in the first terminal with align_depth enabled and run rviz2 in a second terminal.
Then after launch of the camera has completed, record all currently published ROS topics to a bag file by using ros2 bag record -a, which I see that you have already done. Once you have the bag file then you can use it with rosbag2video to convert the bag file to a video. |

@MartyG-RealSense thanks a lot for your response. I followed your instructions and

@MartyG-RealSense I think I was selecting the wrong topic, I may still be. I selected a different topic from the metadata.yaml but it seems the source is empty. I did capture for a few seconds. Is there a way to check sanity of recorded before converting or why do think I am getting this error? I have: |

In regard to the global status error, what happens if you change Fixed Frame from 'map' to camera_link please? In regard to your other questions, I do not have information about how a rosbag recording could be sanity checked and are not familiar with how rosbag2video works. I do apologize. |

Description
I want to save the capture in .mp4 format for use in upstream app. I am able to view the feed in RVIZ and record the capture in bag files. I don't care about the method or package used as long as I can get a depth align RGB feed along with depth from RealSense D435 camera that I can save to a video file (or a series of consecutive frames).
