HELP – DVCPRO HD 720p60 to HDCAM 1080i

[Shane Ross]

Why are you messing with any of that? The Kona 3 will cross convert 720p to 1080i on the fly as you output. What do you need? 1080i29.97 from 720p59.94? No problem.

What settings to change? Not sure…I do this at a post facility. Next time I’ll arrange to sit in the drivers seat. But I know you do this thru the Kona Control Panel.

[Serac Adventure Films] “OK, i have a timeline that’s DVCPRO HD 720p60 and I need to layback on HDCAM 1080i.

i have FCP 6 and a Kona 3”

You do this in realtime using the Kona 3 Control Panel. Leave the 720p timeline alone in FCP and leave FCP in the Easy Setup for AJA Kona 3 720p/60 DVCPro HD

In the Kona Control Panel

Primary Output – set to 1080i/60

Secondary Output – set to 720p/60

Kona will cross convert the 720 to 1080i in realtime to the HDCAM deck and it will be pristine. We’ve done it here and it works perfectly.

Walter: can you tell me some about up conversion with hardware from SD to HD? How it works? Get we a better quality than using software? Why?

Yes, the Kona will convert the 720 to 1080 – but in the final cut pro timeline, the TC goes up to ;60 frames, whereas I need it to go up to ;30 frames. Just like a 24p timeline goes up to :24 before turning over to the next second.

HD is all 60 frames ( 720p) or 60 fields ( 1080i) for this workflow

1080 29.97 is a different way to say 60i (29.97 frames x 2 fields is 59.94)
the timecode will match what you set when you black and code the tape on the HDcam deck.

This is the same process we all use and I have mastered literally 100’s of tapes in the very same workflow.

great – so when i go to edit to tape – even if in my final cut pro timeline if i’m at 1:10:15;59 – if my tape was coded at 29.97, my deck will be at 1:10:15;29. I’ll try it today. Thanks!

BE SURE you calculate for difference between the DF 1080i TC vs NDF TC for the 720p material.

and by this you mean? The total length will change or something.

[Serac Adventure Films] “and by this you mean? The total length will change or something.”

720p in FCP uses non drop timecode.
1080i60 uses drop frame timecode for most deliverables.

the length does not change, the counting does.

Well, so i went in to layback this morning.

with my aja kona dvcpro hd 720 59.94 sequence (wouldn’t let me make it DF in sequence settings) – told the kona to make it 1080i. Picture is no problem, but couldn’t get it to edit to tape. It would just hang a couple seconds before the edit ‘in’ point and not start. give some servo lock error. I striped the tape both DF and NDF and tried it both ways.

i tried my 1080i pro res timeline to the tape and it worked perfectly.

is there any ‘eureka’ here?
