Frage von silentzero:
Does any of you, which subsampling the EOS 550D has recordings on video? 4:2:0, 4:2:2 or 4:4:4? Or someone knows a tool with which I can analyze a recording on it?
Thank you and Merry Christmas.
Antwort von deti:
4:2:0

Antwort von silentzero:
The images in 4:4:4 but already, right?
Antwort von deti:
The images in 4:4:4 but already, right? No. JPEG makes 4:2:0, 4:2:2 RAW

Wow, now I'm disappointed. Is that true of all cameras? Why never refers to a the full color?

Ok, thanks.
Antwort von deti:
I must correct myself: the JPEG format, Canon is synonymous 4:2:2 - and more in a Bayer sensor, as I understand not. This is how the SOF0 header from an EOS 550D-image:
Component [1]: ID = 0x01, Samp Fac = 0x21 (Subsamp 1 x 1), Quant Tbl Sel = 0x00 (Lum: Y)
Component [2]: id = 0x02, Samp Fac = 0x11 (Subsamp 2 x 1), Quant Tbl Sel = 0x01 (chrome: Cb)
Component [3]: ID = 0x03, Samp Fac = 0x11 (Subsamp 2 x 1), Quant Tbl Sel = 0x01 (chromium: Cr)

The JPEG I do not really care less anyway, RAW is better to me anyway.
Antwort von deti:
The JPEG I do not really care less anyway, RAW is better to me anyway. Subsampling said on Raw makes absolutely no difference!

Antwort von silentzero:
But something has to be RAW's better, right? Otherwise it makes no sense.
Antwort von deti:
But something has to be RAW's better, right? Otherwise it makes no sense. You have no DCT and a dynamic range of 14, instead of 8 bits.

Antwort von silentzero:
Oh, and what is DCT?

Oh, that I have read my views alone. Thank you.
