detailed questions on professional tape formats



Frage von chew:
Juni 2007

Hi,

I have for my FH unit for the subject 'professional tape formats "enschieden. However, I see in some areas after a long search not quite through. Would be glad if you take a look at the following questions could throw.

1. What is the current market situation? Mart Sonyist guide (HDCAM, IMX), how widespread are the tape formats of Panasonic DVCPRO50 DVCPRO HD? DVCPRO semiprfessionellen more in the area used?

2. Sony cameras offer for MPEG IMX and XDCAM to. I thought as synonymous stores XDCAM IMX (MXF).
What saves cam Sony's MPEG IMX MSW-970P? on Prodisc?

3. Is there an XDCAM at MOD (predecessor of the ProDisc?) Stores?

4. Saves DigiBeta IMXs as synonymous metadata MXF file? What are the advantages of bringing the metadata?

5.IMX has a worse than Bildqual Digit Beta IMX since only a maximum 8-bit quantization (DigiBeta 10bit) and by offering an mpeg compression of 3,3:1 in contrast to 3:1 in DigiBeta arises?

6. When you use HD-SDI? Should Kinoroduktionen yet to HDCAM cassettes or stored directly on hd-sdi to raid systems? sdi is the system with a normal IP based network comparable?

7. What is the difference between SDTI and SDTI-CP?

8.redcode is a file format such as MXF?

EDIT
9. gibts ne it with the full list of standard Dx as D1, D5, D9, which is standard of sony or panasonic?

To these questions I find on google only sparse information and then answer the question.

I will try in my spare time on some of your issues, but I will not have the time for extreme details.

1. What is the current market situation? Mart Sonyist guide (HDCAM, IMX), how widespread are the tape formats of Panasonic DVCPRO50 DVCPRO HD? DVCPRO semiprfessionellen more in the area used?

Yes, Sonyist leader, however, not only with HDCAM and IMX, but especially with Digibeta.
DVCPro is available in different designs. DVCpro25 is with Sony DVCAM of comparison, a mixture of semi and the lower end of Professionally. Differences between formats of Sonykannst you find on Wikipedia as I think.

2. Sony cameras offer for MPEG IMX and XDCAM to. I thought as synonymous stores XDCAM IMX (MXF).

XDCAM is NOT the name of a recording medium or format, but for the entire workflow.
XDCAM moments may include the following format: 25MBit DVCAM, IMX 30Mbit, 40Mbit, 50Mbit. This format will be as one. MXF - File stored on the disc. There are still XDCAM HD, which in turn DVCAM 25MBit and mpegHD with 18Mbit, 25MBit and 35MBits to disc stores. 2007/2008 appears XDCAM HD 422, which is probably all XDCAM format and XDCAM HD, MPEG HD and an additional 422 with up to 50Mbit or more is processed.

What saves cam Sony's MPEG IMX MSW-970P? on Prodisc?

NO. IMX - Cameras' save 'the data on tape (with 50Mbit). The tapes have the same sizes as DigiBeta or Betacam. You are in the green shell.
Very important: IMX tape format means no, but a file format. The files are then used. MXF - Files responsive, synonymous on the MAZ.

3. Is there an XDCAM at MOD (predecessor of the ProDisc?) Stores?

No..

4. Saves DigiBeta IMXs as synonymous metadata MXF file? What are the advantages of bringing the metadata?

No, DigiBeta stores no metadata, because no DigiBeta filebasiertes system.
Metadata: This is the same material as the primary data, only with lower Resolutionund poorer image quality. These are very small in Gegensatzt to the original material. Benefits of the whole lot. They ask the relevant s.besten Sony - through brochures. There is an XDCAM workflow - Guide. www.sonybiz.net

5.IMX has a worse than Bildqual Digit Beta IMX since only a maximum 8-bit quantization (DigiBeta 10bit) and by offering an mpeg compression of 3,3:1 in contrast to 3:1 in DigiBeta arises?

So I have exactly the data is not in the head. The question is, how much of this quality difference is still visible.

6. When you use HD-SDI? Should Kinoroduktionen yet to HDCAM cassettes or stored directly on hd-sdi to raid systems? sdi is the system with a normal IP based network comparable?

HD-SDI is always there, where a high quality must be transferred. Application areas are diverse.
Live transmission, dubbing the intersection place, ...
Yes, always run with cassettes. These synonymous s.besten Sony, through brochures, many PDF files online.

No, SDI is not an IP-based network. SDi - specifications and application areas such as safe can be found at Wikipedia.

So, for the other 3 questions I have now unfortunately no more time. Enjoy yet.

Schöne Grüße,
Robbie

1. No.. DVCPRO (50) is standard on ZDF and other individuals. Nevertheless, it is more commonly used for EB. DVCProHD is rather scenic used. Shorts, movies, Intermediates for cutting. For example, for the channel as Dicovery MAZ format.

2. IMX can tape and optical disc are stored as MXF. XDCAM HD MXF is always packed.

3. Afaik no.

4. No.. Scene selection and control, independent and safe time code, erasure of garbage directly s.Drehort, more data codes such as recording time / Aperture / Technical values.

5. No.. The Compression of IMX (MPEG-2) is better than Digibeta. But the disadvantage with the 10 bit remains. And this is not always used. In the post-production visually demanding productions during grading or intermediate Exports (advertising, CGI elements) make 10-bit color or just when gradients quickly noticeable. Nevertheless, they always sent in 8 bits, therefore we are arguing about the meaning may be.

6. No and no. HD-SDI Application: Monitoring s.Set, studio recordings, Umkopieren (as well as SDI today in the studio technology) or direct recording of high-quality productions. For example, Russian Ark was with HD-SDI via a 10-bit 4:2:2 HD signal. Directly into a HDCAM SR recorder. The SDI-definition, you can even really read. The recording is under budget and purpose. Meanwhile, set things in movies, and more on 2k cohorts, because on HDCAM. Counter-example 2001, Lucas, Star Wars rotated only on HDCAM - today he would no longer make.

7. No clue.

8. Redcode is primarily a new codec, which is a 1080i signal memory effectively in a secure file. With MXF afaik has nothing to do. REDCODE (RAW) seems to be proprietary.

Can it be that you just "metadata" with "proxy data" would confuse? You've just "proxy data", explains, while "metadata" additional information about the picture and sound, for example on the selected resolution, the date, time, the name of the cameraman, comments on the scenes and so next. Now I know not what of now both the Ursprungsfrager wanted to know.

Pianist is right.



Antwort von chew:

thank you for your reply.

Of course, I've been in the wikiedia etc SDI viewed items. There is talk of coaxial cable. Wen coaxial higher I think I s.die old ring network topologies my old school. So a network system before today's RJ45. Is there a composite handle between this old system and sdi or only the same cable strands used?

MPEG IMX and XDCAM cameras save it as so as IMX. MXF files, only the storage media is another?

On what kind of band saves the MPEG IMX camera? HDCAM tape?

Metadata are also with those of comparable digital cameras only the addition geringaufgelöste Videofile a quick sighting store?

k there is MPEG IMX Tapes

I see this correctly the einzgste the RED ONE digital cinema camera is a file stored?

In what one media stores such as the viper genesis and Arri or d20?



Antwort von PowerMac:

Sorry, but the last question you find yourself synonymous raus! There is not only the Wikipedia in the world. The Sony-Business/Panavision/Arri/XY-Page helps you next synonymous.
SDI has absolutely NOTHING with IP technology to do so. Cable similar nunmal: everywhere electricity flows through:) The only question is HOW the currents flowing ...?



Antwort von PowerMac:

Metadata unequally proxy data. When you read is not what you wrote?

The point is what you called "digital cinema camera," described. Do you include a camera, which for the production of feature films is used? Or any electronic camera, a Resolutionvon at least 1920 times 1080 pixels offers? Then came the Ikegami Editcam HD synonymous in your list. Maybe yes sometimes synonymous someone a cheap movie with an XDCAM HD (PDW-F350) ausbelichtet and rotated, then the synonymous to your list. And like the previous cameras Arri D20 usually draw on a HDCAM SR recorders (SRW-1), so a digital video stream and not a File.

Oops, yes. To quickly read or thought ... there was probably the thought process "to metadata gibts eh no questions, which certainly says proxy data" ...

But luckily there are so many people in the forum:)

Beautiful Sunday
