Gain Test -- XF 305 native .MXF files from Nick Wilcox-Brown
From Nick:
"I have just completed a set of tests of gain settings for XF305, XHG1s and EOS5D Mark II - all of a GretagMacbeth / XRite SG Color chart. The XF305 gain settings were tested from -6 to +33db. +21dB looked very clean while I was shooting it. All files from this camera are pre-production and subject to change."

Gain Test -- XH G1S HDV files from Nick Wilcox-Brown

See this thread: http://www.dvinfo.net/forum/canon-xf...mxf-files.html for viewing tips -- the VLC
player is inferior to the free Sony XDCAM Player and other free options. When commenting about a specific clip, please refer to its file name (8601.MXF, etc.). Thanks, |
Very interesting. Chroma noise is filtered out but Luma noise is left in.
Can we match "gain" to an EV (exposure value)? |

Very interesting. The only setting I would never use is +33 (blue noise), the other settings look really good. I would like to see them compared to the Canon HDV models.

Glad this was helpful Floris. I have the matching XH (G-1s) files here (also EOS 5D MkII) and will upload them shortly.
For the XH, I have used the default Canon settings as opposed to my favourite preset. I am sure that Chris will kindly put them on a similar link when he has a moment. |

Is there a higher noise reduction setting? |

Nick, Chris:
Thank you for sharing these samples. |
Nick and Chris, thanks for your effort!
Compared to the XH-Series noise is very fine grain (higher bitrate and 4:2:2 sampling might help the XF) and the registered trademark sign on the Macbeth chart is still readable even at high gain settings. Blue noise seems to start kicking in at around +18dB. I ran your previous clips through some CC tests in FCP and what can I say? I like what I saw! |
