Hola a todos,

He notado una diferencia en la respuesta del Vectorscopio del VMix comparado con el vectorscopio del Davinci Resolve en tiempo real.
La prueba puede hacerse en tiempo real seleccionando la misma entrada en ambos softwares y comparando la lectura de ambos scopes.
Los puntos de colores claves son precisos en ambos casos pero los tonos de piel por ejemplo dan un error de unos 10º entre ambas "skin tone line"

I have also felt that there was about a 10 degree off issue, but I have not had any time to put together a test.

pabloloc,

Can you send us some video from the source for analysis?

It could be due to the colour space conversion on the source, we have seen this on systems using
Intel graphics and on some video formats where the colour space is reported incorrectly.

Regards,

Martin

Thankyou for your help with this.
The latest update to vMix 21 (21.0.0.55) includes a re-calibrated skin tone line that should be a lot better.
