Sony HD Cam to Dvcpro HD

[Peter McAuley] “Gary if we can not transcode how can I do this through the Kona 2 to dv 50 24p. It only uses firewire.”

The Kona 2 will not cross convert between 1080 and 720- this is a known.
IT is not an issue with conversion to other fame sizes only these 2 HD formats.

– HOWEVER it will convert from either 1080 or 720 to NTSC On the fly – you have the ability over HDSDI to capture the 1080psf datastream and directly convert that content to DV50 on the Fly with the K2 using the HDSDI source ( you can also do this from Dual Link)

I do not understand where the FW comes in Peter? this is totally a function of your Kona 2 reading an HDSDI stream and converting your HD footage via hardware to a DV50 stream so that you will be able to edit offline and does not have anything to do with anything FW.

Yep, Upconvert and Downconvert are great functions of the Kona 2 via SDI. The ONLY thing it can’t do is the cross convert between 720p HD and 1080 HD.

Peter,

The question here is whether you want to cut in HD or not. Gary is right in that the Kona 2 will not cross convert HD 1080 to 720.

Going back to your original posts:

HD OFFLINE
1. So you can easily cut 1080P by capturing the DVCPRO HD codec at 23.98 but the 11MB file size is to big.
2. You can only cut 720P if the footage is transcoded (media managed or compressed) from 1080P to 720P

SD OFFLINE
3. The Kona 2 downconverts to SD onthe fly and you can pick any SD codec to capture to. Anything from 10bit uncompressed to DV.
4. You want to maintain a 23.98 workflow the KONA 2 will do the 3:2 pulldown o nthe fly as well.

My only two questions?
1. Is this a film finish?
2. Will SD downconvert mean having to run the project through Cinematools?

No cinema tools needed if capturing directly to 23.98.

We will be conform back to 10 bit 23.98 HD master that will go out to film and creating a 1080i master as well
I think I’m all clear on this offlining worflow now Thanks David and Gary for youe expertice.
Cheers
Peter

Well I seemed to be able to bring in dv50 at 23.98 fine and dandy, but it is anamorhphic not letterbox in a 720 X 480 frame. I guess the letterbox down conversion on the Kona 2 only works when you have a hd file and you want to play it sd out. Now the HDCAM deck has the letterbox downconvert for sd out but that is at 29.97. Am I stuck with anamorphic in dv50 in order to get 23.98.

Cheers
Peter

I think you grabbed the wrong setting. does your capture setting say anamorphic? did you try turning that on in the seq presets so that the footage plays correctly?
This is a operator error problem – you just did not get the settings right.

Thanks Gary

I just did another test. I captured two clips .Clip 1 was checked 16 X 9in its’ capture setting, clip 2 was unchecked. Sequence 1 had 16X9 checked in its’ sequence settings. When I edited clip1 (16×9) into seq 1 my canvas showed thje omage to be 16×9 but my SD sdi out monitor showed anamorphic (squeezed). Clip 2in the canvas appears 16×9 but in the sdi out it is pillar boxed. In Sequence 2 (16X9) not checked clip 1(16×9) appears as 16×9 in the canvas and 16×9 in the sdi out. This is what I was looking for except that it is showing with a green line on the timeline asking me to render this. Although my machine is ffast enough to play it , it is neverthe less asking me to render. clip2 in sequence 2 apppears anamorphic in both canvas and sdi out. I guess the question here is whether or not I can capture a 16×9 clip that doesn’t require rendering in the timeline in order to have letterbox out to my sdi and composite monitors?

Pete,

Why not just switch you monitoring to 16×9 when you are editing.

David

[David Battistella]

Pete,

I do not think that the KONA will convert SD anamorphic to Leterboxed on the fly. I think that it only does this when it is downconverting. I would capture everything anamorphic and then switch only your output monitor to anamorphic (if it has this capability and then the monitor will be doing the corect aspect.

If you go to tape (d-beta for example) then you will have to cerate a letterboxed sequence by nesting the anamorphic sequence into a 4X3 sequence and doing that render.

You are getting the render bar because you are asking FCP to do this render from anamorphic to 4X3 on the fly. It’s actually pputting the 16×9 footage into a 4X3 frame for you. This is the same as doing a motion effect. If you were to look at the motion tab in the “green bar” footage you will see that it is correcting the aspect for you. The render free way of doing this is to capture 4×3 already letterboxed, I think that the F-500 will do this on the downnconvert for you and you can put thte source TC in the letterbox and mask it when you are outputting.
