Infoseite // Loss of quality when importing as DV



Frage von UliS:


Hi,
I'm here just before despair. No matter where you read anywhere is that when reading it as a DV-AVI is no loss of quality. Is there yet: I clasp the Camera to TV s.ist everything beautifully, already dubbed the DV-AVI 's pathetic to see out. Water glistens so that one is glad to be able to weggucken, the sky is white instead of blue, the colors are pale, all in all, the recordings are simply modest. I burn them to DVD, watch them closely so s.TV. No Comparison to the tape.
No matter what program I suppose, always the same. Szenalyser, Video Studio, Windows Movie Maker, Virtual Dub, everything no preference: the result is the same. Did someone perhaps a hot tip for me? I know that is no longer next .....

What did you do for a camcorder?
What captures you? About FireWire or analog?

Antwort von UliS:

This is a SonyDCR HC42, and I capture via firewire.

Antwort von UliS:

So, I've a short test video with Scenalyzer recorded, ie directly by the Cam of Firewire on the plate captured. Perhaps sacrifices and yes someone is looking at the times (40MB)? Wäre echt nett.

Thanx,

Antwort von Meggs:

Well - really bad.
What I noticed besides the colorful reflections of the water:
Extreme chromatic aberration, vignetting strong above 32kHz with 16 bit sound.
The image errors are in direct connection s.den Television can not see?
Chromatic aberration is actually a mistake from Lens, the vignetting synonymous. So regardless of capturing always be there.

Codec? I thought if I select DV-Avi, the transmission without compression? How can I check for / adjust?

Antwort von SusinaBerlin:

Technically, dubbing a DV tape via Firewire a 1:1 dubbing. With it would be new if it Quallität lost.

However true s.PC monitor for two reasons to see video images are not so great. Firstly because of the interlaced material on a PC screen progrssiven (results kammartige disorders s.senkrechten edges) and then the color differences remain synonymous. Because it can come to irritation. Do you have the opportunity to watch the video image on a reasonable path from the computer to a TV monitor (eg AD-converters s.Firewire port)

To Clip: First round surprised me the above disorders s.Bildrand. It seems to me with a not so great optics or a lens to have been worked. These images should be considered s.TV really look better?

I have in any case with DV AVI files captured via firewire Quallitätsprobleme had been no ...

The pictures are with a Helmcam and an external Micro (see

Antwort von darg:

Again, with what you've captured this? About Scenelyzer? Although some of the program hold a great capture but I would not. I have times for the separation Scene used but more so I would not make synonymous.

Maybe show that it looks like the original better than VCD 360x288 but I would not judge

Well, then maybe you have chosen an unfortunate example. I can imagine what the HC42 for images makes the Helmcam I can not say.
In principle, the digital data from the tape are identical with the digital data stored on the hard drive. This is regardless of synonymous Capture Tool. I capture everything with Scenalyzer years and have never seen a bad experience.
What each is different, is the player. Time, the HC-42, sometimes a PC player, now a hardware DVD player. Possibly. yes you see when you play on a PC other than what I do. Maybe yes synonymous conceals the HC42 when playing exactly the things that disturb you.

Szenalyzer I have now only taken to quickly upload a short film, but it looks really Progs with all the same. Usually I capture movies directly to video with Pinnacle Studio, which is synonymous in policy or?
Previously, I had s.liebsten with Ulead VideoStudio worked until it suddenly just jerky movies ausspuckte. The only prog, with which it ran smooth again, it was just Pinnacle.

Perhaps this is because your problem (or your computer). Something is no longer the way it should be.

A question about your receipt remark: You're saying if you put the camera directly connected s.einen TV it looks good. You mean so that the live image of your camera, the live image of your helmet camera or the recording of the helmet camera to tape? This is something I have not yet so clear.

The recording of the Helmcam on the tape looks better. When the Camera with interleaved tape is connected to the TV, and I have already burned DVD to play left, I can even switch between the middle of recording tape in the Cam and burned DVD, and just because one sees clearly that the recording on the DVD much paler, and simply überlichtet quality is worse.

This is not directly comparable, because this is a picture from the DVD player and the other comes from the camcorder. So these are two different DA-transformations, and maybe even different types of signals used by the Television uneven process. For me, the synonymous quite different from, if only because my DVD player via RGB and composite via the camcorder is connected (in my case is the quality on the tape detour computer DVD even significantly better than directly from the camcorder). In any case, never the same on the screen at.

In between, there are nonetheless Kodierschritte!
So the DV-camera optimizes its output to PAL norm. Since everything looks good. The camera knows halt their own weaknesses. In addition, the Television Camera as well as the apparently synonymous Interlaced a working device. So the whole fit together well.

To view the same on a DVD player for a pack, the DV material into MPEG2 transformed. This is a Kodierschritt required! This much can go wrong.

I have looked at times viewed the video (although on Linux) and can no special "About Radiation" recognize. There are just the usual Interlacedartefakte highly visible. The sky is cloudy but synonymous a sky blue is clearly visible.
