DVCPRO HD to DVD

[Noah Kadner]

Try an export of your FCP timeline directly to Compressor. Then use the Quick NTSC presets- not the High Quality ones as they are buggy in the current release.

I’ll be getting my camera and manual pretty soon but I wanted to ask about this question. How can you shoot in interlace and progressive at the same time? (1080i 30p) The SDX900 sort of makes me ask the same question because it lets you pick between 24p, 30p or 60i but then there is also a sub menu which asks if you want to shoot interlaced or progressive. Its an active choice and the footage doesn’t look any different to me one way or the other. Can Someone explain that one to me?

As for the DVD’s how mch 1080, 720, native and un-native HD content can you put on a 4.7gig DVD? What about a dual layer dvd?

Chris that sub menu choice that is referencing the interlace or progressive is really a resolution question and is aimed at giving you all the resolution that your delivery medium can handle. If you are delivering to a TV station, you should use the interlace setting as that will roll-off the excess resolution that will cause a problem in broadcast TV. Progressive setting is perfect for a film out.

Hope that helps,

Oh thanks Jan!!! That has been a question for months now that I haven’t gotten a good answer to. Thank you. I suppose I still don’t know what is happening technically but that’s ok. Is there and explanation in a white paper? I suppose if a client asked me to explain to them whether or not we’re shooting actual progessive or interlaced footage I’d still have to go back and give the utility of each. So is this also a feature on the HVX200? Does it really shoot 1080i 30P? Does the 720 30pn footage you shoot with the HVX200 fallinto the true progressive for film out catagory or the interlaced broadcast ready progressive?

[Jan Crittenden Livingston] “Chris that sub menu choice that is referencing the interlace or progressive is really a resolution question and is aimed at giving you all the resolution that your delivery medium can handle”

Then Jan, is the camera shooting interlaced or progressive with that setting?

The reason I ask is because I trust shooting to this resolution with improve a SD DVD from this source over 720/24pn?

So I think if the camera does shoot in 1080i 30/24p then it explains why Barry Green referred to this camera in a DVUSER forum thread as a 1080p camera. Obviously the menu settings only let you select up to 1080i which would make someone think that the camera is shooting in interlace, but since you can choose 24/30p instead of 60i… it makes a Broadcast ready InterProgessivelaced image… I feel like I’m being asked to chase my tail here. Especially since the rumor of a firmware update is possible that would allow for 1080pn shooting.

Its not the end of the world either way I just want a full and complete explanation. Again if there is a white paper or what have you available somewhere I’ll read up on my own.

{{I have no inside info on this, but I can say with a great degree of assurance that the whole premise of this thread (a new 1080p model etc) is without any factual basis. Especially since the current version *is* a 1080p model…}} — Barry Green

This is not a choice in HD, only SD, and it is really referencing a filter for excess resolution on an NTSC monitor. That monitor can only display about 350 lines, the SDX can genrate close to 450 in vertical. So in interlace mode it filters off the excess resolution, in Progressive, it is retained for film out or bump to HD.

The camera is always capturing progressive as long as you are in 24P or 30P, and we are referencing the 480i domain part of this camera and the SDX900.

I hope this helps,

Hi,

Take a look at the resources and about pages here:
https://www.panasonic.com/business/provideo/hvx200microsite/index.asp

There is a Guide Book on the normal website and that may also prove to be insightful.

Best,

In the SDX, that setting is equivalent to the “THICK/THIN” setting in a DVX.

But the HVX, DVX, and SDX all use genuine progressive-scan imaging for their 24p and 30p modes (and, in the HVX, for all frame rates in its 720p mode).

Think of it like this: in 1080 (or on the SDX & DVX, in 480) it’s genuine progressive footage, being carried in an interlaced bucket. The CODEC is interlaced. The footage is imaged truly progressively. But the codec expects 59.94 fields per second. So the camera slices each progressive frame into fields and divvies them out in a way that the codec can handle it. In post you can un-do that process and end up with exactly what you started: genuine progressive-scan imagery.
