Edit To Tape – Poor Quality Issue
Good evening…
I’m trying to use the Edit To Tape function for the first time.
My clip is a concert of an hour and a half, at the front of which I have bars & tone, and a broadcast clock. I’m working in DV PAL and I’m sending the clip to a Sony DSR80/80P DV Cam deck with a pre-striped tape.
Everything works fine – no problems with timecode, sync etc – it’s just that the recorded picture looks pretty poor in terms of quality. It has a slight flicker, almost like the wrong field dominance, and it looks progressive rather than interlaced.
I’ve tried adjusting the capture format settings between AJA KONA LH 625 25 DV, and DV PAL 48Khz but it doesn’t seem to make much difference.
I’m sending the video signal via SDI from the KONA card to the deck.
Anyone have any experience of this? Have I got some settings confused along the way?
Thanks very much…
Steve.

When I output to the deck using the Print To Video facility everything comes out fine, it just appears to be poorer quality when I use Edit To Tape. However, I have to use Edit To Tape because I require my programme to begin bang on 01:00:00:00 timecode.
Edit To Tape tries to deinterlace the clip, or records it in the opposing field dominance. I just can’t seem to get around it…

Perhaps it doesn’t like your stripped tape. Try an assemble edit instead. I usually leave :30 black between bars and the start of program. I stripe the start of the tape at 58:50:00 and record black to 59:40:00. Then I mark in the timeline and assemble edit at 59:30:00. That way the assemble edit is :30 before program start. May or may not make a difference, but worth a try.

Thanks Lee,
I already tried a different tape but no joy, and I also have all the correct leaders set up too. Everything looks fine when I play to the machine direct from the timeline, but the picture is awful if I play out to the machine using Edit To Tape. I assume it has something to do with how Edit To Tape processes the signal…
I’ll keep experimenting…
Cheers,
Steve.

I fixed it! I changed the field dominance of the clip from “Lower” to “Not Set”, and hey presto…all my stress disappeared into a puff of smoke!

Is the sequence fully rendered? Print to Video tends to make sure that is done.

Hi Steve,
I point the same than Shane. Have your sequence fully rendered?
If you are getting two different video qualities is because one of them is not rendered.
Don’t mess with the field order. Your PAL DV must be Lower First when going to tape.

Guys, Edit to Tape automatically renders everything first, just like Print to Video does.
ETT and PTV should be identical. The fact that Steve had different results between them is pretty damn startling to me.
Steve, I would consider trashing your preferences at the very least. What you experienced should not happen under any circumstances.
