Frage von Martin:
Hello!
I am going to film some reports with a Betacam. Normally this will be cut then s.einem Avid editing suite. But I wonder whether I can somehow convert the material and can then edit at home. (such as DV via firewire in. ..)
The image resolution is indeed the same, would be a data-compression to visible or should I take a different compression. I can then cut at all well at home and spend again? The final product will of course again there on a Betacam cassette.
I have a smaller, project. mov files edited at home, but all too jerky and it was too big to burn to DVD (as. mov) to ...
I hope someone here has experience or is to be managed so that an idea like s.besten too!
Thanks

Copy and paste the material on Mini DV and play it at home of your Camera on the calculator.
The minute plus minus costs ¬ 1.60. Without any costs that are confined not.

But then we would have a loss of quality? Beta has indeed a higher Resolutionwie Mini DV! Or?
Antwort von Markus:
Hello,
Betacam's analog, digital MiniDV. Therefore, the format can not be directly compared. Both formats deliver an SD picture, but the
Resolutionder Color
Antwort von Strahlemann:
The question of which beta format you even talking about?!?
I am going to film some reports with a Betacam Beta SP?
Digi Beta?
Because, if it is analog, then helps you s.ehesten a component input on your PC (Y / C synonymous lot s.Farbinfos) reject ...
If it is to be digitally then SDI would be the right connection ...
I'd play me all in a "modest" quality on my calculator and then s.Schnittplatz, by EDL, the new material (so you do not need to load additional Equiptment-out any video input on your calculator and the Camera)

Hello!
So, Betacam SP has no 4:2:2 sampling! This is very similar!
Visible Resolutionist the same (720 x 576 or 720 x 575), so no problem.
Some of the ways you've already heard this synonymous works:
You can go to Betacam SP Camera Playback s.einen Connect Adapters and of the purely in the MiniDV camera (or a converter). If your MiniDV camera, the signal can be looped through the same, it goes directly into the PC via firewire. You'll get around a little more hardware so unless it can just copy what it costs synonymous.
If you as a reasonable use of the codec can not figure Normalbetrachter was no difference in quality.

@ Chris: "Betacam SP is working with 4:2:2 component recording of a color difference, so) for the luminance (Y a bandwidth of 5.5 MHz and the color difference (RY & BY) each 2 MHz are available."

@ Luke:
Martin could actually only "Betacam" as the format of previous BetacamSP have meant (see link).
Antwort von chris:
@ Mark
So yes, the fundamental frequency is 3.25MHz, therefore 4:2:2 means that for Y are 13 MHz for the disposal or Cb and Cr for each 7.5 MHz.
In general, this term is used only for digital recording. Thus, if 5.5 MHz is available for the 4 and 2 MHz for the 2 is definitely not right! For the double of 2 is 4 and not 5.5!
Betacam SP uses the rest of YUV, where the color difference signals are synonymous reduced, but not 4:2:2.
U and V are in fact not exactly Cb and Cr, but only similar. The names 4:2:2 and 4:2:0 and 4:4:4 are really only in digital format in use. YUV is usually used in analog format and YCbCr in digital formats.
So if there is at Betacam SP, it uses 4:2:2 that is not quite correct.

Antwort von Chris:
What struck me is still just that the samples of YUV 4:1:1 and 4:2:0 ComputerBase with your link ( "link below) are completely wrong. There is 4:1:1 to 4:2:0 the same, only the color difference signals are slightly shifted. So I would not think to give the lexicon. As someone has pebbles something that has no clue!
4:1:1 means that the color difference signals are sampled with 3.25MHz, that is expected in the Picture Only every 4th Obtain the color difference column, but each line as well.
In 4:2:0 falls to 4 Y values each one Cb and Cr. So the color resolution is halved horizontally and vertically!
Here's the link:
http://www.computerbase.de/lexikon/Farbdifferenzsignal#4:2:0
So, the bottom two images of 4:1:1 and 4:2:0 are wrong! Actually, would need to be 4:1:1: 4:2:0 (which requires that the interpolated Darstellng, because in the middle between the pixels can not scan!). The illustrated 4:2:0 is actually equal to the illustrated 4:1:1, as the Fardifferenzsignale are synonymous for 4 Y values.
So the dictionary there is clearly wrong!
