Hello
these articles have good read of rudi
www.slashcam.de/artikel// In-the-depths-of-color - The Horse-of-behind Conclusion ------ --- or-what-you-to-learn-kann.html my question:
what is the consequence if one is filming in 8 bit and then finishing with after effects makes
what must be considered and how should we proceed with the color?
Thank you
Antwort von domain:
As I have understood the article, it means an internal 32-bit float calculation no particular consequence, but on the contrary, that very few adverse effects can occur and most of corrections virtually synonymous reversible.
Otherwise means Farkorrektur IWS first times the contrast of an image, for example with the Waveformonitor on a true black (Bit Values about 15) and on a real white trim (Bit Values between 235 and 255) and preferably without the simple tools of the general simple NL-editors such as contrast and brightness, but with the primary 3 Wegefarbwerkzeug, is synonymous with the lights and shadows separately and specifically beeinfussen can.
After only one progresses to a general assessment of image correction and color in terms of the strict sense, but then usually only slight corrections in the shadows, midtones or lights and are selectively required per color or synonymous times a general lifting or lowering the midtones or saturation.

The article is nich so doll .... Generally you have to give it to you just imagine: Due to the scope limitation are in color or 16bpc Integer 8bpc all colors permanently converted into new color. This means that there is no way back there again to reconstruct the original values, man can only return of the now converted values expected, but not necessarily 100% back to the original values (by rounding and quantization errors). In 32bpc or float 16bpc other hand, will retain all the values first and only shifted (offset). In contrast to the false information in the article, the far wider than 1 or even negative. Only then will be converted for example to Bildschimrdarstellung. Because of a known offset, to reconstruct value, it is synonymous remove this and you come to the original. But this is obviously synonymous only half the truth, of course, synonymous since the precision of s.größer is the beginning and so the rounding errors that somewhere s.der behind the decimal point zweimillionsten happen visually not noticeable, which in turn scih in non-linear corrections for gamma effects etc. ... Is a relatively complex topic, but you usually just for color generally inthe highest possible color depth available to work.

super
Mylenium many thanks for the detailed reply
two requests
- This means that I, for example, a psd into 8 bits of "visual-mode-16 bits per channel" should be converted and then - as described here (synonymous of rudi) to work?

would be important to me this again qualified enough to get
thank again
Antwort von Mylenium:
If you do everything in AE, you need to even do nothing. AE makes such conversions "on the fly." A Vorkonvertierung in PS brings überhaupt nix - yes makes no difference whether it is fully white as 2567256/256 or 1024/1024/1024 is stored. Where nothing is, nothing comes out. ;-) If you have any material from a source you can use it in AE fully ready to go. Color play a role only when you are mixing different materials, such as DV footage with rendered animations from 'nem 32bpc program in 3D mode. If the times, then read the online help (livedocs.adobe.com), because there are many helpful links and PDF documents relating to color. For a normal (amateur) film you do but not usually. Even if you look in the technical sense, the colors wrong bend, which would be visually nothing to remember, because you are all the same bend. The only stumbling block could then render the final output, since several other Quicktime codecs and formats so have their quirks and causes incorrect conversions from 32bpc mode may occur. In that case would be to recommend a level again and Effect as a compander Adjustment Layer above all to forget it, in order to ensure correct conversion to 8bpc / 16bpc values to force.

- What does this mean for filmed material (dv pal) - how do we proceed as
would be important to me this again qualified enough to get For 8-bit original material - depending on the platform for the available programs - a lot of things to consider. Very clearly stated in Stu Masch joke 'Book "DV Rebel's Guide". A simple workflow, this is not the salvation of the circumcised RGB values begins in NLE, and the work does not end with the issue in AAE, as is so often turn an 8-bit format (or a) target, and when the return can be re-gift quality. Generally the processing is already in non-native color depth with a quality loss, but if it is properly made, unique and not visible.
What WoWu always recommended, namely 8-bit color depth synonymous in this to stay, otherwise dithering and banding threatening to take to wherever the color correction is not complex (as complex as it is explained) and the material allows .

In contrast to the false information in the article, the far wider than 1 or even negative. Only then will be converted for example to Bildschimrdarstellung. Only to your criticism into perspective, that is exactly synonymous but the article inside:
And secondly, you are synonymous for values below 0 or above 1 are defined. If that is an overflow in the meantime, it will be without distortion or clipping in the float value is stored. Only the color reproduction will be Clipped or compressed, which in several processing steps can be quite handy. Many greetings
