Einen haufen Fragen zur SONY PMW-EX1 XDCAM EX Camera ???

A bunch of questions about the SONY PMW-EX1 XDCAM EX Camera?



Frage von Channel19:
Januar 2008

@ all

hallo erstmal s.alle and thank s.die who try me in this normenjungel Wust and ask to get to come legally. Thank you!

So ...

I am planning a SONY PMW-EX1 XDCAM EX to buy a MacBook Pro with 2.6 GHz/4GB/SD/17 "with 200 GB - 7200 rpm. and FinalCut Studio 2

but meanwhile I'm still not the perfect interaction of all components convinced. the opinions of the professional traders are quite apart. maybe someone can think of so you help the whole.

1) if I have two 8 or like an 8 or 16GB and a 16GB SxS (ExpressCards) in the record and sony did, I can find out that if the first (slot A) he is full without bildvelust on the second (slot B) next record. But if I remove the first card (in concessions! SxS is allegedly hotplugfähig?) So while recording, and the card in the mac and put the mp4 file on the mac, copy, or verscheibe, and then again this is empty ...
I like the empty back into the insert slot A, and if it is with the second SxS card is full, he then jumps back to the first car SxS card (which is now empty again and back in the camera), so the A slot without visual loss as previously of A to B, and I can fully if the second is the second card in the mac and insert the data move, and back into the cam ... etc. .. to just a kind German endless loop for very long shots. A> B> A> B, etc. ...
Does It Work? what problems are there for when yes / no? someone has already tried?

2) I have the SxS cards synonymous with the time code preformat as the bands that can predict with a black image with the time code preformat need to work professionally and to be able to restore and then yet to know. ;-) If so, how do I make the skin on the SxS with the time code before and how does that then interact with endless A> B> A> B, etc. .. I have always given all the files with the same time code of either the first or the second card. I am not into knitting, files with the same time code, etc. .. says what about Final Cut Pro? knows the outstanding? sschon because someone has tried?

3) What is the maximum data rate, the SxS card? According to wiki 2.5 Gbit / s? can that be? which means 2500 MB in the second? This is not a read error? because if it 2.5Gbit / s would be the 312.5 MB / s. is probably not? nity as synonymous only SATA 3 Gbit / s ie 300 MB / s. (I know because he is conversion 1 / 10 and not like the other 1 / 8) I mean the play on the notebook is certainly faster than the recording. there's even trying, how long does a full 16GB card with full hd with 35MBits / s recorded on the macbook pro to copy? the SONY PMW-EX1 can with a maximum data rate of 35 Mbit / s recording. that is if I am not mistaken 4.375 MB / s. this is not much? apparently, I am mistaken or there? I am in what order the statement?

3) I could tell the record in full hd, also with 1920x1080i or 25p on the synonymous sdi or firewire port directly on the macbook pro to stream?
I get my order to circumvent the kartenwechslerei. The problem, however, when the lecture takes 8h say, I have 1 File, because I will be so mad at the cut, how big is the maximum Filesize the mac, ie when HFS + I believe 16 EIB (according to wiki), or 16 exabytes. na bravo!

4) What HD-SDI output, the Sony PMW-EX1?

Default Name bitrate video format
SMPTE 292M HD-SDI from 1485 Gbit / s 720p, 1080i, 1080p
SMPTE 372m Dual Link HD-SDI s.2.970 Gbps, 720p, 1080i, 1080p, 2K
SMPTE 424M 3G-SDI from 2970 Gbit / s 720p, 1080i, 1080p, 2K

Metadata SMPTE 292M HD-SDI support the transfer of metadata, in addition to the Picture-and Toni formation. Examples include text information, time code, or encoded signals in EDH, VPID, and SDTI.

can be the PMW-EX1? what they can and what is not?

5.) the files on the SxS cards are supposedly. MP4 files. it means there are LONG GOP MPEG2 data, so in real MPEG2 embedded into MPEG4 files? can FinalCutPro with the MP4 files of the SxS cards immediately to go? can I get this file immediately cut in Final Cut Pro? without lästi



Antwort von WoWu:

Phew, have lots of questions but I will try, a part of it to answer.

I can tell you any specific answers to questions EX1 because I did not. There would be one of the proud owners demanded.

Basically to
1)
Yes, tickets are hot swopp bar, when the speed of transferring and deleting the external fast enough, will work with the Wechselei. I would recommend, but a third card.
I do not synonymous, the clips if you do not even have the need to delete Camera menue, because at the time of initial use of the card is a file that is located in the bath blocks are registered and of course can not be accidentally erased, because the listing at Initial installation is created, because the card will usually do with "bad blocks" Dealing with these meta-data is to be treated with caution.
It is likely, but the manual information.

The Mac supports the EX1 format in version 6.0.2
http://www.apple.com/support/releasenotes/en/Final_Cut_Pro_6.0_rn/

2)
Before you can encode the cards, because the TC in the transport stream data are integrated and integral part of the record is.

3)
SxS cards to make about 800 Mbit / s and only in the burst, and under very limited conditions, they are up to 2Gbit / s, but only in short bursts.
But the 800 Mbit synonymous depend on the flash type, and word length with which the Registry.
P2 incidentally makes 640 Mbit / s. But the inner workings of such a storage technology, especially for real-time applications is not just words, as explained in 2 different but rather of the use of photography.
If you are interested in such issues, I recommend the uALink

The main difference is synonymous is that file every few seconds, closed and verified, in order to check data errors and losses in order to avoid image.
That you have not in HD ... if you have to work, nothing can really happen synonymous. Therefore, I would always recommend Capture program, which supports such mechanisms.

3)
Sure, you can both about one thing, as synonymous to the other, depending on the hardware interface your computer. The MacBook for example, has no HDSDI, so FW is only in question because you have but the coded signal on it. About HDSDI normally get when the cameras good signal before encoding offered. As for the EX1 because raustut times you have to explore in the manual.
About the MAC Filesize you need not worry about it ... And finally, no PC, but as already mentioned, a capture program has additional features and makes several files from the current signal.
Good Capture Programs make the files available even in parallel, so while you will still, they can already be retrieved.

4)
HDSDI single link you need for more 1080i25 not synonymous.

5)
MP4 is only the container (File) format, in which everything is possible, that is synonymous MPEG2 can be scanned.
To Cut and Final Cut Pro how to handle it, do not worry. Also, the cut is obviously frame-accurate possible but a bit too long to explain.

6)
You can not say what is better or worse. The fact is that the PCMCI Association has advised its members to refrain from any further development towards more PCMCIA to make, because the format will no longer supported.

7)
Skip your break times, I now

8)
This really is here on the fast does not explain ... synonymous since the recommendation link below.
Or at least the small-format HD-Overview:
http://www.auberge-tv.de/Whitepaper/High_Def._Formate.html

8)
If you are from your camera HDSDI output from the signal (semi) transparent synonymous did you find out after all the possibilities, even without an MPEG codec (IMX) to go.

Supplementary question: The Pfilichtenheft are of the ORF. Very friendly people there and a phone call is enough.

Do you have the recording with bands actually still made? This procedure is actually a relic from the analog days, and on closer inspection is no longer advisable.

Antwort von radiohead3:

the requirement specification of orf, briefly summarized:
IMX everything, if you're very fond of is synonymous DigiBeta ok. gaaanz unless you have special shots, then everything is permitted. and the remaining obligations (audio..) are standard anyway;)

That all depends on. For HDV it can be advisable to vorzucodieren tapes, for example, time code inconsistencies in DV editing with subsequent batch capturing in HDV avoid.



Antwort von Sakas:

That is now a bit off topic, but fits in well with the question:

For all professional productions, it is customary, each tape with an individual time code to it.
In Tape 1 begins with the time code to 01:00:00:00,
for tape 2 at 02:00:00:00, etc.

The advantage is that the editing system every snippet of footage clearly to a tape can match.

While consumer camcorders usually no opportunity to set arbitrary time code, the s.der Semi-Pro class usually do (eg SonyV1E, FX1).
, JVC HD-100, etc)
An unpleasant effect when recording on tape is that the camera time code each of the front (ie, usually at 00:00:00:00) can start when the tape or battery from the camera away and were brought back.

You have manual or via "End Search" function to connect s.das turned it on the tape to restore a continuous time code.

"Preformatted" tapes do not have this restriction, because the camcorder to the existing time code does not clear, but simply used.
The exception would be a tape with several clips, each of which with a time code of 00:00:00:00 begins. If this tape in a camcorder s.Stück recorded, is the first time code and existing bodies s.denen he starts again at 00:00:00:00 will be overwritten. Ultimately, you get so synonymous with a universal time code (except for tape or camera battery in between will be removed and used again).

I have, however, the pre abandoned, as I believe the Kopfverschleiss s.Formatierungsrecorder no relation to the expense of the use of the "End Search" function.



Antwort von PowerMac:

Your questions are all really interesting. Normal HD-SDI, no dual-link. Why synonymous? The cut works. The SxS Rüberziehen of the Mac is five to ten times as fast. Times, times like that. Time codes you can forget it. The course will be during the written. That has nothing to with the band of operation to be done sooner. 1920x1080 you can not record directly via firewire.

I have the PMW-EX1 only borrowed and must re-emit. When I turned the MP4 files to play on my calculator and my Final Cut Pro 6.0.2 buy next week, then I can import these files and easily edit?

Thank you
