capture DCRTRV17 in tape mode only saves fragments
on Mar 9, 2019 at 1:01:03 am

Thank for any help -
capturing DV tapes from DCRTRV17 in "tape" mode.
process seems simple, but does not work:
I press record on premiere capture, I press play on DCRTRV17 -
tape plays for usually 30min+
I press esc to end, I log the clip
however the resulting clip is always usually only 1 or 2 minutes long (and from the beginning of the clip)
happens regardless of tape

any ideas?

thanks

What connection type? How much available storage?

And the dirty little secret of miniDV - are these tapes recorded at LP speed? If so, is this the cam they were recorded with? If not, they may not play back properly no matter what you do. LP often will only play back clean on the unit it was recorded with.

System:
Dell Precision T7600 (x2)
Win 7 64-bit
32GB RAM
Adobe CC 2017.1 (as of 8/2017)
256GB SSD system drive
4 internal media drives RAID 5
Typically cutting short form from UHD MP4, HD MP4, and HD P2 MXF.

Thanks so much for your response Jon,

Dv tapes were filmed on the camera.
running from camera via rca to canopus advc55 which is then connected to computer with a fw600->fw800 cable w a thunderbolt adapted
into macbook pro retina 2015

multiple TBs of avail storage

the capture window show the video playing the entire time until i end capture with esc but then only a fragment appears to be captured

tried in imovie and it generates a series of individual fragmented clips that have slight jumps in time.

the camera is still operational and the problem is systemic over all tapes. so i'm not sure what the weakest link is.
but would love to some sort of brute capture that ignores any problems on incoming material / rewrites tc / just ingests the raw footage warts and all, clean or unclean.

I think I would skip the mess you got and simplify connections - i.Link out from camera. What Sony says here:

I don't know the Canopus, so I don't know if it has any kind of TBC options. But you could be getting some kind of degradation causing the problems. I don't know, I'm guessing. But you should be able to easily simplify the setup and not go through the A/D conversions.
