Codec - Capture ?

Codec - Capture?



Frage von Fridolin:
Juni 2006

Hello,

must annoy you again!

For several days I was a little busy with the matter codec and must admit that I'm probably too stupid ;-) I just do not understand it. Ok, that a codec is the responsibility of a format eg AVI to MPEG compression, I have buckled. How does that look when capturing? Here are just 1-1, the data stored on the hard drive was no preference for a system or be converted by a codec in a different format. Can I get as capturing in VirtualDub and then edit them in without any problem with the Magix formats with no loss of quality and expect to have?

Perhaps someone can even pity me and enlighten me :-))
Thank you!
LG
Fridolin

macht ja nix :-)

to your question:

So ... You have a camera that takes mini-DV format .. (minidv an uncompressed format and is) in this "raw quality" very good. If you are via Firewire eg dubbing case you create a kind of '1to1 copy "in the same quality (we recognize s.den vast amounts of data - several GB for a few minutes) on the PC. Stop! And now the crucial question is ... What I want to do with the material or ... medium on which I want it now "immortalize"?

As a rule, on a DVD! So the material means of procuring suitable codec to DVD size is minimized rendered /. This happens eg with the MPEG2 codec. Eg something like this could take synonymous Virtual Dub ... or any other editing program. It can be used to integrate various codecs, of course, synonymous to a Schnittprgramm /. After rendering you now will get a DVD compliant MPEG2 file that can be burned to DVD or find erstmal in an authoring program further use. Importantly, if there will be a video DVD, it still convert VOB files to "." This now play almost all video editing programs automatically.

Do you want to use another medium eg Divx (to get it to a CD, you're on a DIVX codec ... for one VCD MPEG1 codec etc. everything clear?



Antwort von Fridolin:

Thanks SteveB!

Compliments for this forum !!!!! ;-) You been very considerate

What you have written, yes, I understand. I have become synonymous understood that there are different for the compression of MPEG codecs synonymous. maybe I'm on the line, but then why do I need a DV codec, if the Rohmateriel is uncompressed eh?








Antwort von steveb:

But then why do I need a DV codec,

what do you want to use it?



Antwort von Fridolin:

what you would use it? :-)

Objection, Your Honor. MiniDV has a compression ratio of 5:1.

The material is not minimized, but also optimized (quality to data rate / data) and synonymous not rendered, but encoded or transcoded.

This is ONLY with an encoder and one MPEG-2 codec with. There are applying cutting programs, which includes an encoder and a codec or codecs installed on your PC.

true ... my formulation was wrong.

render the wrong name is true - that code is correct.
material is optimized when not coded because the ergebniss "will be worse" than the original ... so would minimize correctly.

I can integrate multiple codecs into my cut programs, of course, not simultaneously use ... but I had not written synonymous ..
