I wish my DV - Video capture osae.! In the Prog can I set different codecs: Nativ, DV Codec, etc.. What exactly is virgin video?
Gruss UE
Antwort von HPS:
Video = native uncompressed video. For example, digitization of analog images (Betacam, S-VHS, Hi8) in an NLE without compression rate. FAST Video Machine used this for further rendering. Playable) was the clip (not too large data streams. New, modern NLE systems in the broadcast sector now dominate this possibility.

Hello HPS! So when I capture analog images and digitize it wants, I have to choose virgin video so as not to compress all this?
When I capture my DV material, I have to select DV codec? If so, this will in turn place a compression? If it is compressed but here again what I have to set the then so that the computer hardware unchanged (no loss passes) from tape to hard drive to it, then edit in Media Studio?
Thank you for your answers!

Antwort von LuFaHa:
Yes, you need to select the DV codec, you if the capture of DV. No this is not compressed AGAIN. Has already been compressed in the recording. DV (Digital Video) stores the captured video directly in digital form (with ones and zeros ...). In the DV codec is used. When capturing of DV material is copied these ones and zeros on the calculator, but in real time, speak for Picture Picture, Sound on Sound. There is no way to record uncompressed DV, since it is already compressed. The DV codec uses a picture compression, ie it is not time (MPEG), but compresses each picture. There are in fact similar to JPEG grouped similar areas. Important terms is to the sampling rate (4:4:4, 4:2:2, 4:2:0). In any case, the data-compression for the Bildqulität is quite good and makes only keyen or really demanding finishing problem. In this case, you should not rely on compressed devices with 4:4:4 sampling rate.
I hope you understood everything. Otherwise, you can even googled a bit under those terms.

Hello "UE"
With what program Dost Thou by the capturing?
Antwort von HPS:
Hello, the issue of DV material digitize the previous speaker has dealt with comprehensively. Analogue video could you need einzuspielen synonymous but not natively as it brings no advantage in quality. With adjustable compression you go out with analog material without subsequent Qualitäsverlust of the following rates:
Betacam 1:3 to 1:5 S-VHS / Hi8 1:5 to 1:8 VHS / Video8 1:8 to 1:10
In many nonlinear editing systems can become the compr. factor will no longer be freely chosen, so that it is not necessary then. With analog recording of material and conversion to DV-AVI is predetermined before the fixed value of 1:5.

Does this mean that the appropriately selected DV codec while capturing it (in terms of quality differences!) Is irrelevant?
I assume that the DV codec is only there during this process, which (to see) So Decoding?

No, there is a wide flood of codecs on the market with different quality characteristics. One thing they all have in common, the compression factor of 1:5. And as I say, give me my old FAST Video Machine with Motion-JPEG codec (HW), because I can choose the compression factor and achieve outstanding images. By natively 1:1 to 1:200 for the foremen.
