Respuesta: Calibrando JVC HD950
Deja que ponga en duda eso de por vencido...,por lo demas tranquilo me he estado empapando de información,puede que en algunos casos tengas razon como que los reproductores recorten la señal a (16-235),como muestra puede ser el reproductor de windows media que si he obserbado que para el todo color negro inferior a 16 directamente lo iguala a 16, pero en reproductores tipo el VLC si que muestra toda la paleta al igual que en el media player clasic.
Si el video de resident evil se hubiese querido mostrar en la escala 16-235, lo hubiesen tenido muy facil igualando la información,pero no ha sido el caso, y cuando quieras te pongo numeros de niveles de la grabación.
Y para los que no entiendan lo que digo os lo pongo facil,si hay una imagen de una chaqueta de color negro y los colores de las arrugas son del tipo RGB (10,12,10) o RGB (13,12,14) directamente no veremos esas arrugas al igualar todos los colores a RGB(16,16,16) de minimo..
Pues me da que vas ha tener que seguir empapando muuuuuuuuucha más información de la que te has empapado hasta ahora ...................
Otro poquito de ayuda.................:
"The Decoder’s parameters are explained in details below. Depending on the DV input
material some checkboxes may be disabled.
Decode to CIF size is a special option for decoding. It decodes DV-AVI with a quarter of
the resolution, which can be useful on older PCs. This option allows fluent playback of
files. It allows the following settings:
Manual MainConcept DV Codec • page 3
Quarterly PAL: 352x288
Quarterly NTSC: 320x240
Fast Decoding decodes in fast computing mode. Although this option enhances speed it
is prone to errors.
The option Change field order reverses the field order of a frame.
Disable 16:9 turns off the widescreen format.
Using the setting RGB 16..235, particular black and white values are preserved. During
encoding and decoding the RGB color space with R=G=B=16 is used, which corresponds
to the color black. Furthermore, the RGB color space with R=G=B=235 is used, which
corresponds to the color white. Normally the values for white are R=G=B=0, and for black
R=G=B=255. The specification ITU601R now defines black (Y=16) and white (Y=235),
i.e. the real video signal receives values which are “blacker than black“ or “whiter than
white“ (so called super-black and super-white values). These super-black and superwhite
values get lost in the normal PC RGB 0..255 color space, but they are preserved
with the RGB 16..235 option."
"The option Create DVC-Pro 25 MBit is self-explanatory. It simply creates the DVC-Pro
format. This format is mainly used in the broadcasting area.
Suppress DIF-Pack header enables you to hide the Dif-Pack header. It is only used for
special DV hardware, which works with Dif files. Dif files are a kind if raw format.
The settings for Video for Windows almost correspond with the DirectShow settings.
However, here are a few remarks about the differences:
Using the setting RGB 16..235, particular black and white values are preserved. During
encoding and decoding the RGB color space with R=G=B=16 is used, which corresponds
to the color black. Furthermore, the RGB color space with R=G=B=235 is used, which
corresponds to the color white. Normally the values for white are R=G=B=0, and for black
R=G=B=255. The specification ITU601R now defines black (Y=16) and white (Y=235),
i.e. the real video signal receives values which are “blacker than black“ or “whiter than
white“ (so called super-black and super-white values). These super-black and superwhite
values get lost in the normal PC RGB 0..255 color space, but they are preserved
with the RGB 16..235 option
If you tick the Clamb YUV to ITU601r option, the super-black and super-white values of
the decoder are clipped in the ITU601r valid range during export.
After you have adjusted all parameters, click the OK button to confirm the settings. Otherwise,
press the Cancel button in order to abort the process. Click the Apply button so that
all settings are accepted."
