The Tiffen 125mm Coarse Thread 85C Color Conversion Filter helps to decrease the color temperature from 5500 to 3800K, allowing the use of tungsten-balanced film in daylight conditions. The warming effect of this filter requires a 0.3-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 2. Audio Channel Mapping - SDI Audio 1&2 - Can SDI Audio 3&4 be mapped to 1&2 and still maintain original source of 1&2. In other words, can the Decimator MD-HX be used to combine 1&2 + 3&4 into 1&2 without destroying original 1&2? Why? Audio Mixdown for Streaming. If this would work, would be a less expensive alternative to Teranex 2D.

A: I do technical support for Symbiosis, Decimator's master distributor in the US. The MD-HX can remap audio channels to move incoming embedded audio from a pair to one or more outgoing pairs, including between groups. It cannot currently combine audio pairs to perform a mix-down.

A: Unfortunately I don't have this specific camera, but I have used many different HDMI sources and exported the audio with no problems out of the HD-SDI output. Sources include Canon C300, Canon C300MKii, PS4, GoPro Hero 3+, PC with NVIDIA 1070 GPU, and even a SCART to HDMI converter I use with vintage computers. Perhaps you should slo check that you have your camera set to output sound via the HDMI output.
