Isaac Sim 2023.1.0 movie capture can't combine video and with some bugs!

Hi, I found Isaac Sim 2023.1.0 version movie capture without the combine .mp4 file function.How can I add this function?
When I use the move capture to record a video, only fps60 mode is used, other fps settings will make the system crash.
When I recorded the video, some frames displayed strange visions as following picture.

Normal picture.
Strange vision.
