H.264 > HDV Conversion / Acquisition
 
I recently hired out for a video project due to being double booked and the professional I hired out to did not deliver raw footage from the cameras (I assumed he would), rather delivered the footage pre-ingested into Apple FCPX. I personally still use Apple FCP 7 and typically ingest from my Sony HVR-Z7U in HDV straight into Final Cut from the CF cards. The footage he delivered reads in FCP as 1920x1080 frame size and H.264 as the Compressor. I would like to convert this footage to HDV (my preferred editing codec) (via FCP's batch export) but it is taking FOREVER... about 24+ hours for a 1 hour clip. I have also tried doing this with Adobe Media Encoder (I am slowly but surely migrating to Adobe) but still having the same problem. Is there a better way I should be doing this? I have about 5 hours worth of footage to convert which would take about 5 days which I think is pretty outrageous. Any help or light anyone can shed here would be immensely appreciated. Thanks in advance!

ProRes HQ is my intermediate codec of choice for FCP. If you re-compress to HDV, it will look worse than the source because of HDV's MPEG-2 compression.

No need for ProRes HQ, you can use ProRes "plain vanilla" or ProRes LT. h264 is an 8 bit 4:2:0 type of codec and there isn't enough information preserved in it to warrant the larger file size of HQ.
