OK, this is simplified since codecs typically don't distribute data perfectly per frame like that, but you get the idea.Īs codecs become increasingly sophisticated, they can deliver the same quality with less data thanks to advanced algorithms, The flip side is that they become more computationally intensive. If you have a bitrate of 10.000 kb/s and you have a clip that is 25 fps, you'll have 400 kb per frame at your disposal. But as it turns out, normally we can do quite a bit of compression before visually losing image quality.īitrate is "data over time". Jpeg compression is destructive and data gets discarded. If you add more compression you'll get smaller files, but at some point they will start to fall apart. jpg you know that there are variable levels of compression.

But if something is going to take 10x longer and take up 10x more space, I need to see some improvement. I honestly don't really even know what bitrate means and what number I should use. But anyone have any idea why the default bitrate went from 10,000 to 125,000? I know I can manually change the bit rate, and I think I will from now on. When I view a project that is 125,000 vs 10,000 kb/s, there is no difference in quality(very similar projects). This must be an overkill and perhaps even an error. This means the rendering takes 10x longer, the file size is 10x larger and uploading to youtube takes 10x longer. Now the automatic bitrate is about 125,000kb/s! A huge jump. When selecting one of these options there are preset settings, one of these is the "Quality" which is referring to the bit rate.Ībout 2 Davinci Resolve versions ago, the automatic bitrate for 1080 was about 10,000kb/s. Under the "Deliver" tab, there is a "YouTube" option with 3 sub options(2160, 1080, 720).
