• Scene detect is not available when capturing HDV in native Premiere Pro. Use a third-party plug-in like AspectHD or as Trent points out:
It's a few more steps, but if you really wanted to capture clips via Scene Detect, you could:

1) set your HDV camera to do HDV to DV conversion.
2) Open a DV Project. Do your Scene Detect captures. Export a Batch List from these clips.
3) Switch HDV camera back to HDV mode.
4) Open an HDV Project. Import the batch list and capture.
