[QUOTE="Steve McDonald, post: 3790094, member: 22915"] I bought a Canon camera a dozen years ago, before there were very many discussion forums to exchange the information, that is not provided by the manufacturers. The controls for features such as Contrast, Sharpness and Color Saturation were hidden in a place that was accessed by a button that was separate from the main controls. Nothing was explained about it in the printed manual. It took me months, before I learned that those controls even existed or how to work them. For the small number of us who come to these forums, this is no longer a problem as we can help ourselves. But the other 98% of camera users have not discovered this option. One suggestion is to read the manuals in other languages, as sometimes, more information is provided in them. Many online translators are available to assist in this. I'm impressed by how many of those from other countries are becoming so fluent in English, mainly due to their school systems, that teach it from the first year of enrollment. In the newly-released manuals for the SX70 by Canon USA, there seems to be nothing about the video bit-rates for various modes. But on their website, they have separate information pages with these details. The bit-rate for the highest quality level of 4K 30p or 25p, is 120 Mbps. For 1080 60p or 50p, it's 60 Mbps. These bit-rates are higher than is used by other manufacturers of similar models. The Nikon P1000 uses a variable bit-rate (VBR) for 4K 30p or 25p video, of about 78 Mbps. A higher bit-rate actually makes it easier to decode and render in editing, as there's less compression, although the file sizes are larger. If you experiment with the bit-rates of edited 4K production output, it's surprising how low a rate is needed to provide playback quality of an adequate level. [/QUOTE]
