I am creating videos for teaching classes online, using the Screencast-o-Matic Pro version and a basic Logitech headset with a microphone. I am getting a low video bitrate between 150 kbps to 250 kbps whereas the website on which I host the classes has a minimum bitrate requirement of 300 kbps, and they say that 3000-5000 kbps would be ideal.
I tried to create the same videos differently, first by re-recording them using SoM, then using Audacity and the Ocenaudio separately for audio and then inserting it into the video, but to no avail. The bitrate is always low and I don't know what to do. I also used Handbrake to increase bit rate but the result was just a marginal increase.
I am unable to figure out whether the low bitrate is because of the recording software or the audio output of the microphone or something else. I may not want to use something more expensive for recording the videos like Camtasia immediately, or get a top-end headset microphone, but if there is no choice I may have to.
Any help would be appreciated.
