Is this different than #1166 ? Possible duplicate.

Different, 1166 is a known issue with that video. The annotations just need to be cleaned up on disk due to incorrect fps in the csv file.

This one is a video and pipeline alignment issue when running pipes on the data, or related

Possible solution: use a KWIVER pipeline for trans-coding the video when it's available now that KWIVER has an ffmpeg video writer node?

Matt could you verify that running that pipeline through extra_video_frames.sh at 1 FPS is giving the proper frames. I took the video embedded frame numbers and ran the extraction and the frames it was giving back were not what I expected. Let me know if you want that version of the video with the embedded frame numbers and times.
