timestampfile.txt missing for VirtualStage

[superfluousIT]

It fails when reconstructing the video. It is looking for timestamfile.txt file which is not there. What am I missing? I assume this file should be created/generated somewhere? I am running with --no_kinect_mask option

Traceback (most recent call last):
