I have successfully record the bag file of realsense camera(D435i) topic using:

ros2 bag record /camera/color/image_raw

when I use ros2 bag play rosbag2_file to play this bag file,I use ros2 topic hz /camera/color/image_raw to check the fps of the topic, the average rate only have about 8.

No doubt, I checked the fps of the same topic when directly launch the realsense node.It's about 20.

There were something wrong about the ros2 bag record?

Thanks.

Are you using the latest master (from source) or dashing? I haven't tried that on my machine yet, but does the amount of messages in the bag correspond to the 8hz or 20hz? Meaning if you record for 5 seconds, do you have 100 or 40 messages in the bag?
