Capturen von MiniDV's auf PC - Qualität abhängig von Grafikkarte?

Capture of MiniDV 's depending on PC - the quality of graphics card?



Frage von MiXMaster:
Januar 2006

Hello estimated community

is the capturing of a miniDV camcorder via firewire to a PC depending on the outcome of the used graphics card?

Because of the already digitally transmitted data to the PC's gross profit would, therefore, the AVI file, regardless of the actually used its graphics card - or am I wrong here?

Best regards and many thanks for answers!

Peter



Antwort von Crippler:

The quality is independent of the graphics card, because the signal does not even happen at all, the card graphics. You're going via Firewire, and clean the transmitted data of the camera are stored directly capture of your program on the hard drive. The quality of the resulting AVI file is therefore completely independent of your graphics card.



Antwort von Ripley:

Thanks for the answer! :-)

A "salesperson" trying to convince me that the quality of the AVI files of the quality of the graphics card and depending on me, of course synonymous Sell one like superteure graphics card. In my rejoinder, that it makes no difference when importing, which graphics card is present, it is easy to "become angry" and said that this was perhaps earlier times, but now no more. * g *

Well, try some people's stop with all means.

Thank you again!

Peter








Antwort von Jan Peter:

Hi, would there ne other question, how is that when playing off on MiniDV? Does it make a difference because that graphics card (or if it's a good or less good) is the material renders before playing off?

Antwort von Jake the rake:

The graphics card is only relevant in the presentation!

This does render your CPU and the quality you decide on your settings!



Antwort von Jan Peter:

Ok, cool, thanks. (Ie, only a short time relevance for understanding for me;)) is the graphics card just for showing it on the (closed s.den PC) Screen, but not for the video itself, then what ends up on the tape, right? Thanks again for the quick response!

Originally, the graphics card a pure output device, and had nothing to do with the data processing. Today, graphics cards have often synonymous computing power with them to the processor for some tasks (such as rendering of videos can help). The impact will affect the speed, but not on quality.



Antwort von Jan Peter:

Cool, wieder was gelernt!
Thank you!



Antwort von beiti:

Especially in IT, it is indeed that, normally, the bulk of the material will not be rendered, but again 1:1 output. Really only be rendered transitions, expansions and effects (one speaks synonymous of "smart rendering").



Antwort von Jan Peter:

Yes .. I only have the problem that I've recorded with nem (inexpensive) miniDV camcorder in widescreen mode. That is this "fake" widescreen, so that he was just the picture so distorted that it has in the broadening of the correct proportions. I then got into a Premiere project settings with PAL widescreen recorded and processed. When I play it now, he's playing again distorted ( "with eggheads out." And if I were the tape on the camcorder and playback via AV / Scart transfer to a television that plays synonymous distorted. So now I probably need a new Premiere Project to PAL 4:3 create, import the old project and play by the whole "movement"-effect scale and with bars at the top and bottom. Here it must unfortunately everything is rendered.
Or if I stand on the hose, and there are ne other, far simpler solution?

Believe it or not: You have taken very well in the "real" widescreen format. PAL video is always x 720 576 pixels, regardless of the aspect ratio (keyword) "rectangular pixels". Distorted ( "egg heads"), it seems only when it is not interpreted correctly in playback. This is a problem of reproduction. The material itself is perfectly fine.
Television 4:3 in 16:9 format or later-Television recognize the format is correct and switch to auto. If they do not recognize it automatically, you can switch synonymous manual. But perhaps you still have a very old-Television, which can no 16:9 display.

Some camcorders (such as most of Sony) can (16:9 display - Video when played back on TVs such as the old letterbox can be set somewhere in the menu). Other camcorders (such as most of Canon), but it can not. Then you have a problem.

That would work. It is called the format "letterbox". From a technical perspective, it is annoying but the worst (because quality-) solution, and the latest after-purchase a 16:9 TV you would yourself about your recent films have played like that.

Do you have a DVD-Burners? Then you could burn of the movie DVDs. The current DVD player can output the 16:9 format flexible (true 16:9 for Television with corresponding function + 4:3 letterbox for old Television). Probably needs to be so because the vast majority of feature-length DVDs in 16:9 are stored, and which would be shown without corresponding function as distorted as your own videos.



Antwort von Jan Peter:

Yes, I had thought that synonymous, that the camcorder that outputs as a letterbox - but, unfortunately, is not synonymous and have found nowhere one menu item for it. Is a Canon "MV650i.
Hm DVD burn was possible, however, have since made the experience of their quality. Pretty gaudy colors and distinct artifacts (at least I think there are any), such as an iris-circuit video transition effects to black very distinct "spikes" s.Kreis .. is a question of Qialitätseinstellungen? Respectively. I get space problems on the DVD, the video is about 67th Minutes, dual-layer DVDs, I can not burn, however, only "normal" ... ?

Canon has such a letterbox function unfortunately never brought to pass. My MVX3i it can not synonymous.

Up to 120 minutes you would normally get without a significant loss of quality on a single-layer DVD. If that's you is not so, You used a bad encoder - there are huge differences in quality. Even when adjusting you can do something wrong, ideal is a high data rate (so that the film stop, it should fit on the blank), and 2-pass VBR encoding.
