What is bitrate?? And what bitrate should I use??

[BillyVlogsTV]

I am using a advanced video editing software called Filmora and when I finish my video in the options there is something called "bitrate" and there is numbers such as 8000, 15000, and the maximum is 30000 Kbps.

But I don't really know what bitrate is for or is very good for?? Does it make the video goo a lot smoother when having lots of multiple things in that frame or 2 in the video??

Because I am making some BIG improvements and changes to my video and one of them is the "Types of Drunk People" video and when I separate the audio from a video file and that audio playing over the top of the video file(in some cases 2 video files at once) and when my characters talking and after when I finished the video there is some noise when it goes on that audio in the video and the noise only takes only a frame only right at the very start or the end of the audio and and the noise stops and the audio is fine and I really want to get rid off that noise.

So I am wondering will having the bitrate on like 300000 Kbps instead of 10000Kbps will get rid of the noise that I am having??? If not then how to get rid of the noise then??

And what about the audio?? When I have the audio on 320 Kbps instead of 256 Kbps?? Will it get rid of the noise that I am having at the moment??

Bitrate is pretty much how much information each pixel has, so the more information a pixel has the more clearer it is (usually) but it also makes the file size bigger. For some reason I can't links in my reply so to find out what YouTube recommends for the video just search "YouTube Bitrate" and click on the first link.

Bitrate= bits per second. Bitrate x video length = video file size (eg 500MB or 3GB etc. Note there are 8bits per byte - 800Mb = 100MB and 8Gb=1GB etc.).
The higher the bitrate the more accurately the final video file represents the video and audio from your edit.

I'm afraid changing the bitrate settings for video or audio is not going to solve your noise issue. You need to sort that out in your editor or source files. Bitrate is one setting when you export and can only effect the export. The process of exporting is just writing all your data in your edit to one video file that anyone can play. Changing bitrate just changes how accurately your computer is able to represent your video, audio and yes noise. Hence a high bitrate will just result in a crystal clear rendering of your noise with all its pitch, tone and detail subtleties!! By contrast a low bitrate will result in a rendering of your noise that sounds like its been played down a telephone line.

To put it bluntly, changing bitrate is just fine tuning how both the good and the crap in your edit gets exported, so just get rid of the crap in your edit in the first place and 95% of your problems should disappear. Then worry about fine tuning export settings.

P.S: sorry don't mean to sound harsh if it comes across that way - I do feel for anyone that has to for the first time wade their way through the complexities of video exporting with so many video containers, codecs, each with millions of settings like bitrate, variable bitrate, pixels, 2-pass encoding, progressive/interlaced... Enough to make anyone feel dizzy/sick!
