DV and HDV

[videopetur]

I have a JVC GY HD100 camera, that can film DV and HDV.

For any pressent normal use I would only need DV, but could I film all the time with HDV, and use the same fottage in a DV project?
The benifit with that would be that I in future will have all the fottage I shoot now in HDV.

[zoobie]

exactly...shoot HDV all the time
most HDV cams allow output of DV or you can convert HDV to DV later

[videopetur]

So i supose there is universal agreement on this :P

[Soopafresh]

HDV all the way

[turk690]

SHoot HDV. Tapes will always shed material every time they're played. HDV is much more critical than DV and with that in mind, use NEW tapes for every shoot. Never re-use. Which is a moot point anyway because you'll be archiving all your HDV material now for your future all-HD workflow.
And for the moment, with the correct s/w & h/w, for my eyes, HDV material downconverted to DV looks more gorgeous than it if I shot it originally on DV.

In US I supose you have 16:9 as standard screen ratio?
Here in Europ we have 4:3 ... so, when I film HDV I get a lot of 16:9 fottage.
So I see 2 ways to end up with a 4:3 SD finishproduct of my 16:9 HDV fottage.
1. I make a new project with SD-settings (720x576) and import the HDV fottage ... put it in the timeline and reduce the size down to 80%. That makes it fit in hight, or

2. I produce a finnish HDV edit, export a HDV movie. Then I make a new project with SD resolution, and import the HDV exported movie, and por the size to 133,4 % so it fits the whole poicture.

What would be the best way to go?
I realy dont want to mess opp the quality of the fottage in the editprocess.

Corect s/w and h/w?

I have made a HDV and a SD version of my 4,5 min long fottage. Both of them are 0,97 GB

[zoobie]

HDV is squished on the tape at 25mbps...same as DV...but using a different codec
bwahahahahaha

[videopetur]

uhh :P
Yes, I think I have understood that part.
HDV is packed and fit on the mini-dv tape.
I just dont know how to get the HDV fottage out of the camera with out it being 16:9 and supersized. I have understood that I can import the HDV fottage in 4:3 DV format directly? Wrong?

That all depends on the specific gy hd100 modes available. I don't have one but you can find modes in your manual.

A typical HDV cam records HDV only in non-square pixel16:9 1440x1080i (with display h expansion to 1920x1080). This is all standard HDV.

Some like yours also do 720p usually as 1280x720p (square pixel) or 960x720p (non-square pixel).

If you want 4:3, shoot with masking tape on the viewfinder then crop the center 1080x1080 for 4:3 then resize to 720x576 for 4:3 SD.

Well, thanks very mutch for answering me, but ... there are several things I dont understand with your answer ...

Look, the only tutorials I find are about basic stuff. I know that.
The manual is no use of you dont understand what 1080i is, or 720p ... the manual dont explaines.
Where do I find that expleined?

ATSC and DVB broadcast digital standards are well defined. Use Google.

Both use square pixel 1920x1080i and 1280x720p HD standards and non-square 704x480i/p (ATSC) or 704x576i/p (DVB) for SD.

HDV camcorders record to non-square 1440x1080i or square 1280x720p or some non-square 960x720p.

ATSC standards are either 59.94 fields per second or 59.94 frames per second (720p and 480p only). DVB is usually 50 fields per second or 50 frames per second (720p and 576p only).

What part of that is unclear?

Question: Is your JVC GY HD100 camera a North American or Euro model?

øhh .. well, first. Its a Euro model I supose. I didnt know there were differences.
I can change from 25/50 and 30/60 I thought it was for euro and us, so I could shoot both, I guess not.

well, there are many things that ar unclear to me.
I looked up DVB and ATSC, there are standards, DVB retiring any time sone, and HD-standards coming along?
Well ... so HDV is not a fixed resolution? And I can chose progresiv or interlace scann freely? It dosnt effect the result? I dont understand this.

Why would I not as default chose to film the higest resolution my camera would offer anytime whenever I film?

[edDV]

But is it the North American model (59.94Hz.) or the Euro model (50Hz)?

This is a major issue.

Well, I dont know, and I dont know how to find out.
Im prity sure its a euro-model. Its sold here in Europ.
How do I tell? It dosnt say on the cam or in the manual.

[videopetur]

acording to http://www.ofview.com/wiki/index.php?title=JVC_GY-HD100_FAQ I cant output DV directly from the camera.
In the manual to the camera it says: HDV fomat can record and play back HD or SD video on mini DV casettes.

[edDV]

This N. American brochure says HDV and DV are supported, also 720/576/480 progressive at 50/60fps and 576/480i at 25 or 29.97fps so it looks like you are set for either side of the Atlantic. This should all be in your manual.

Yes this is in my manual. Thats what I said I thought I could film for europ and n.a.
But, I still dont know how to get my HDV downconverted to SD :P

Thanks for the booklink, I will purcast one.
