When recording video using the built in feature, the resultant video isn't realtime.

So it may be because my sim actually only displays like 25fps, but in the end the video is actually 1/2 as long as realtime. Is there anyway to have video actually record realtime and not just based on frames?

To my knowledge, there is no way to precisely control the timing of the frames, as they don't have a timestamp attached to them. The videos are constructed based on the specified frame rate to the video encoder as the frames keep coming.

If you are interested, I have the gazebo_video_monitor_plugins package. I use the timestamps on the videos to keep track of time.
