There should be no need for this.
When you import a video in Ardour, it is transcoded to a proxy video:

  - mjpeg codec
  - fixed fps
  - intra frames only, no grouped frames

trading off file-size (and quality) to be able to reliably seek to any
video-frame with little CPU overhead (also audio is stripped off the
proxy video).

Did you select "Reference from current location" without transcoding the
video? and if so, why?
