This provides the compression to encoding speed ratio. Refer to the documentation of your specific streaming service for bitrate recommendations. Make sure you understand what they mean, and visually inspect your output. by customizing the -b:v/ -crf, -preset, -maxrate, -bufsize, and -g options. It may not be relevant for your use case, but these three params are very useful in certain circumstances.Note: You may have to tweak the commands and settings listed below, e.g. *always* check your audio-visual (aka lipsync), especially towards the end of long assets in case there were any adverse effects. These three are really useful for HLS and DASH to "sharpen" up the frame rate to create a segments with very even durations. vsync cfr sharpens it all up and, I believe, has the added advantage of setting the appropriate CFR metadata
I'm not usually a fan of applying significant changes in frame rate (such as 30>60fps motion interpolation) unless there is a very good technical or creative reason, but, if the source has an annoying fluctuation in frame-rate, the following can be used to bring a slightly fluctuating frame rate to a constant, target cadence. If you are not targeting a particular frame rate, but just want it to be constant, -vsync cfr is great. It is a bit of extra processing, but all three do a great job. And to add to e-Rotoscope's reply, if you want to meet an exact target frame rate, using all three of -vf fps filter, -vsync and -r (after the input) together gives you a very constant frame rate.
