Frage von michi meier:
hello together,
have a question s.die experienced wg a bluebox aufnahme:
the material is available as a digi-beta 16 / 9 before and I have no sdi input.
it could be now for the blue boxes
- With an EDIROL vc-300 at 1080/50p output after HDV (Canon HV20) überspieln (but this has to give a more stable picture?)
- Or do I just to 1080/50i (HDV?)
or as a normal DV and stream everything else anyway in AE
I like it later s.einfachsten when keyen?
Thank you for your efforts
michi
Antwort von robbie:
Digibeta is SD. Why do you want on HD hochkonvertieren I do not know.
What is your final format / product?
AE has a very good keyer, in my opinion you have no difference between i and p.
At a DV stream is to convert the easiest solution would be the best quality, of course, an SDI input, which may let you get the cutter to make another on an external hard drive ...
Antwort von michi meier:
hallo robbie,
sincere thanks for your reply. has helped me.
wg on HDV high copy - had thought that the EDIROL the 16 / 9 and I better make this quality with HDV getting better as a dv-with large pixels. but it's looks like I only do 'nen datenwust unnecessary ... (?)
with regards from schwabistan

Antwort von tommyb:
You only resize your data high. Here you win nothing, but lose again s.Qualität.
If you Digibeta available, then you should restore it via SDI (synonymous if you do not have it) and then s.Besten uncompressed.
Otherwise there is the J30 Player (rent!) Of SONY, which gives you hardship to a DV firewire signal out (makes no sense, however, synonymous since data loss).
Antwort von Christian F:
Hi Michi,
I would just drop in EDIROL call to hire a test can get.
They are quite as straightforward.

Hi Michi,

They are quite as straightforward. And what is this now available?
I think the tip is via SDI s.ihn yourself, as has been frequently mentioned. The rumgepfriemel about the Edirol converter brings nothing s.Qualität.
Antwort von WoWu:
@ Michi
And nothing brings SDI synonymous, because it only describes the hardware interface. The video goes on synonymous Base tape.
SDI So in your case involves only additional AD / DA conversions and is anything but a better picture.
Antwort von tommyb:
SDI So in your case involves only additional AD / DA conversions and is anything but a better picture. Better Picture may not be, it is clear to us all.
But the loss may be at a lower transmission than say Firewire (DV 4:2:0).
This can be seen in every elderly AVID to restore the original color, etc. and that would deliver the best result to keyen.
Antwort von WoWu:
SDI is just a hardware interface.
You have to SDI in this case a digitized analog signal. If you like the analog output of the Digi-Beta and go in the AVID encodierst save you a D / A conversion. Baseband You searched for DB way or another, SDI is a pure transmission line. Prior to that, it is behind Baseband and initially synonymous.
One must distinguish between a digital format and a digitized signal. The digital format of the beta is proprietary and will not be made available to the outside.
And FW, the DB does not (as synonymous?)
This can be seen in every elderly AVID to restore the original color, etc. and that would deliver the best result to keyen.
But this has nothing to do with SDI.
Antwort von tommyb:
Wait a minute. This means that on the 1st Digibeta tape no and 0 be saved? Why is it then Digital Betacam? Or you talking about the analogue of particles on the tape?
Antwort von robbie:
I understand this as follows:
band of the digital signal as an analog component signal "output" and then either as an externally managed, or back into an SDI stream changed.
So no tape -> tape but sdi -> analog component -> sdi
However, I must confess that I have is new. I must look at the datasheets of maz detail ...
Antwort von WoWu:
So it is ... You must be very exactly between an interface and a coding differ.
This is precisely the difference between, for example, a DB and a DVCPro.
When the DB to get with the encoded signal is not next, because it is not outside, is in the DVCPro but very comfortable.
DB does ... from a YUV (analog) signal 10bit DCT Compression. The compressed signal to the outside but is not available and therefore synonymous nowhere can next be processed. Even if it has an SDTI rausgeben could no standard decoder so something.
It will therefore be an analog signal YUV s.Output changed back again. Now you can and reciprocating it either directly from the analog signal (YUV), in a re-encode the AVID you can of course be only a "digital transfer" in SDI make it and then transported to AVID, the ensuing until YUV then be extracted and Encoding .
It remains, however, that once the signal is analog.
Advantage of SDI, SDTI, as is that Picture, Sound and TC (sometimes synonymous metadata) has only one coax running.
When the base is DVCPro coding as a record and can be transferred without additional coding next processed.
At IMX to get through SDTI s.die encoded content, but can only synonymous IMX decoder so as to start. No standard MPEG2 decoder can utilize the signals. But at least you could cut in IMX ... and then again on an IMX output device .... or just in a different codec transcode. But with Digi-Beta, the nix.
Antwort von tommyb:
That's scandalous!
And I always thought SDI> SDI = 1:1 copy ...
