![]() You can upload just about any kind of video to YouTube, from the video you just shot with your mobile phone to your latest 4K video production. Some codecs are still in use for compatibility with older cellphones, and newer codecs such as VP9, are used to deliver 4K content. H.264 is the codec used by most of YouTubeâs video streams right now, but there are also other codecs in use such as VP8. For starters, YouTube uses more than just one codec, and each codec is encoded to multiple resolutions and bit rates. Well, thatâs a good idea, but it doesn’t exactly work that way. So what video format does YouTube transcode your video to? Maybe you can match its settings and keep it in the same format so your video doesnât need to be transcoded. Instead, you always want to upload a high quality video to YouTube. You don’t want to upload a highly compressed, low bit rate video. The important thing to remember is that anything you upload to YouTube will be transcoded. The individual video streams range in resolution and video quality from tiny postage stamp sized videos, all the way up to 1080p and 4K. This allows your video to playback smoothly on everything from mobile phones to desktop computers. When you upload your video to YouTube, its video servers kick into action and start transcoding your file into a set of optimized video streams. When you know what’s going on behind the scenes, you’ll understand the best settings to use and why you should use them. Good when you have critical info in the lows and can't lift the overall exposure because it will blow the highs.To answer these questions, it helps to know how YouTube processes your video once itâs been uploaded to its video servers. ![]() Also good on high contrast scenes where you want to preserve details in lows and highs at the cost of mids. Necessary when delivering out of the camera without post work. Uses the entire 8 bit range, so it's the best you're going to get for mids and overall image. Not good if you aren't planning post work. Works for most situations, especially recommended when mids are more important than lows and highs. I.e., which part (lows, mids, highs) gets preference in terms of space on the 8 bits. See comments on the page for the difference and effect on banding. Yes, we know both capture the same info (nothing gets dropped at the top or bottom), the difference is in how they get ENCODED. Basicaly the guy says that there is nothing to gain with 0-255 vs 16-235. Interesting article about this topic but for GH4. You can try applying some dithering noise in post though. 0-255 allows for 256 so that isn't to blame, the compression is. Banding on the NX1 is mainly caused by the scaling from 6.5K to 4K internally and compression, plus the fact that at low ISOs the image is extremely clean so there's no noise to dither the 8bit bands smoothly together. A blue sky for example could have such subtle variation in tone that it gets compressed away and you end up with 4 coloured bands. We are talking luminosity here with the 0-255 'steps' not tonal precision which is what causes the banding. You will not see more banding with 16-235 compared to 0-255. are less discrete steps that might result in banding when grading.Īs far as the lut I doubt there is a difference since the data are mapped in the 0-255 range and rgb space when you are in the nle program. But as soon as it puts them in the smaller range you loose some information. The camera tries to fit the same data into two different ranges.
