With the theory can not serve me, but here is a strong section of an image, where two surfaces seamlessly meet. \u003cbr /\u003e The camera sharpening I set to -10, so the smallest possible value. The normal sharpening of zero results in a significant number of black pixels between red and green, but also the partial overlap in the two colors Einpixelbereich. Do not know if that was as good or even classified as unusable. \u003cbr /\u003e\u003cbr /\u003e url = http://www.fotos-hochladen.net] \u003cimg alt=\

Thank you owner! \u003cbr /\u003e\u003cbr /\u003e I have sometimes the image directly into After Effects with Key-Light keyed. Did the dirt in the mat is not removed extra ... \u003cbr /\u003e\u003cbr /\u003e Here with a blue solid backed: \u003cbr /\u003e\u003cbr /\u003e \u003ca href=\

This can only judge someone who has been the lot of experience in this sector. Taken into account is, of course, that this is an extreme act enlarged, brought the pixel with the repetition of Photoshop only on the size of 500 horizontal pixels was. With this method you can only have the individual pixels of the font seen, with all other interpolating methods would be as pretty everything was blurred.



Antwort von Zworg:

But I wonder how the dark fringes are created by the script. Either sharpen the camera still synonymous at -10 sharpness, or it's a compression artifact (for compression side effect but I think it is pretty hefty for), or was it already there in the original ...? ...



Antwort von domain:

Yes, it sharpens slightly more synonymous with -10, but no Comparison with zero. If you get the ISO test image from the camcorder compared with zero look at factory preset but you will notice that the sharpening is relatively low, there's this white stuff with really very different distinct edges to the lines. \u003cbr /\u003e A certain degree of sharpening must be easy to get around because the noVideokamera and has been synonymous with analog films have always been. \u003cbr /\u003e Somewhat misleading in this image is synonymous, that I have left over it auto contrast and the contrasts were divided hereby enormous. In the original it looks very dull.



Antwort von Zworg:

@ Domain \u003cbr /\u003e\u003cbr /\u003e Thanks for the info with the sharpness. \u003cbr /\u003e\u003cbr /\u003e Have again today at the Canon Support Just Checking, and because I was told that my request had landed in the wrong department, namely at the printers ... well then cheers! \u003cbr /\u003e\u003cbr /\u003e So that is nothing but with the sale ...



Antwort von domain:

Charge you some test images downloaded at 1200 lux of the XF300 and XF100 from Slashcam of the camcorder comparison and look at Photoshop in a very strong increase in the margin especially the tulip against the dark background. You see the difference then. I can not detect, at least none that could be relevant for the green screen. \u003cbr /\u003e And then make the time for the JVC GZ-HM150. As you will see where the differences lie. \u003cbr /\u003e The statements ofCanonwerden probably meaningless, or theoretical in nature, even the man himself is called for analysis.



Antwort von Zworg:

Yeah, I've made. But to compare it is not fair ... \u003cbr /\u003e\u003cbr /\u003e Why? because the JVC is simply grottige images, and this is not a.4: 2:0 color sampling. I've included two Panasonic namely the Sisters AG-AG-HPX250 with AC160 and the Comparison. The one has 4:2:0, the other 4:2:2. Since not much is happening synonymous - and this is a.Folgendem: only during heavy manipulations in color space (such as keying and is an extreme color space manipulation) is the difference of 4:2:0 to 4:2:2. \u003cbr /\u003e\u003cbr /\u003e The XF100 with the JVC is to compare grottigen already almost common-I have long been NOSO images from an HD-Cam handicapped seen. I was shocked when I saw the test images the JVC. There is so much better my alteCanonhf100. But when there's keying with the hf100 been one or the other difficulty. Sure, I like the imagery the XF100's better than my hf100, but that alone would not justify the purchase for me. \u003cbr /\u003e I hope for my future cam on a packed 4:2:2 signal for keying. \u003cbr /\u003e\u003cbr /\u003e Just look mer mal ... \u003cbr /\u003e\u003cbr /\u003e\u003cbr /\u003e Thank you for your help, \u003cbr /\u003e Zworg
