  Hi Posing1010  There is a ROS bag to mp4 video conversion tool called bag_to_video.py

  jsk_rosbag_tools appears to be for ROS1.  

   

  There is a ROS2 converter called rosbag2video but it was designed for Foxy rather than Humble.  I could not locate an equivalent tool for Humble, unfortunately.

  Alternatively, an indirect way to obtain an mp4 of a bag file would be to playback the bag file whilst running a video screen capture tool to record the contents of the screen to a video file.  The link below has some examples of screen capture tools for Linux.

  Hi MartyG, I prefer to uninstall the Humble for Foxy, although it takes more time.

   

  Thank you for your help and time ^.^

   

  Cheers
