Schlechte Bildqualität mit Canopus A/D Wandler

Poor image quality with Canopus A / D converter



Frage von beaver:
Februar 2007

Hello, I hope someone here can help:
My source file is a video cassette. This I had from the VCR with DVD recorder on DVD. Then, the VOB to AVI with vitualdub converted it into Premiere and imported processed.
In slow motion in Premiere creation has led to strong shakes.
Therefore I now have a Canopus 330 A / D converter and borrowed directly from the VCR via the converter included in Premiere. The slow motion are now fine, no bucking.
BUT: the overall image quality is significantly worse than on the first path (visible box). I understand that at all. How can this direct path to the image quality worse than Viderecorder-> DVD-> Virtualdub-> AVI-> Premiere?
I think when the converter does not control for the "pixel size" (if this is the correct term for the rough "box" is.
Council Who knows?



Antwort von Erich:

Hello!
I use de ADVC110. The quality is very good.
If the 330 is not defective, then the picture would have rather better - at least stable.
If several changes made?
Greetings!
Erich

PS
What's that for a device?
330?
I know only from the Canopus ADVC-300

By default, captures what you want? (Target: DV-PAL, as would a DV camcorder connected).

The ADVC-300 (I assume that my test Du) provides an outstanding digital quality. I have this model synonymous in use. If you see pixels is something wrong.








Antwort von beaver:

Tipfehler, I mean of course the 300.
Premiere Project is correctly DV PAL.
Switch 6 s.Wandler is PAL. Otherwise, all other switches to OFF.
The Picture of videotapes (if I remember correctly from the 1.Versuch without the converter on my Movie Maker to work) and 320x240 pixels is yes then (in the converter?) Converted to 720x576.
It would have been my first guess, in the magnifying the pixels just appear. However, as described at the first road on the DVD and virtual dub so synonymous is increased to 720 and the pixels are not visible there, I understand the whole not.
Has anyone an idea?



Antwort von StefanS:

What do you picture?
Schaust You may s.Calculator nim fullscreen mode?
If yes, is not that meaningful.
Can you times a single upload?

Greeting
Stefan



Antwort von beaver:

I have test clips from both paths (A: Video Player -> DVD recorder, DVD -> Virtual dub -> DV-AVI -> Import in Premiere B: VCR -> A / D converter -> in Premiere Recording) in the same Premiere Project and brought a DVD created. Result: A looks good, such as the original video tape (with the only drawback that slow Jerkiness), visible at B pixel (box).
I do not understand.



Antwort von beaver:

... and then of course the whole thing s.TV considered, not just in the PC monitor.

In the course of this contribution, I had time to switch positions in my ADVC-300 listed: Operation problem ADVC-300

The Picture of (S) VHS (-C) is analogous -/Video8-/Hi8-/Betamax-/Video2000-Videokassette and knows no pixels. Only when the digitization of the existing Picture in a pixel grid placed. It is not enlarged, but it will be digitized, as it is.

Now, if pixels are visible, check the times Resolutionder gecaptureten recording. If the Capture settings in Premiere?



Antwort von beaver:

The gecapturte Studio has 720x576 pixels. Apart from that I do not know where you at the premiere recording in the set could be?
The only setting I see in the choice of the type of project is correct and the DV PAL
Gruss



Antwort von Markus:

Maybe a hardware defect exist? - Or is your operating system randomly WinXP/SP2? There were reports of synonymous times verpixtelte DV video images, but the effect was more pronounced as well.

Try synonymous with times
