One of my previous posts dealt with the task of creating a video file out of a still frame. That is as low as video editing can get. Perhaps Assembly rasterisation could be the next lowest level.
All this to prove that simple tools(like VirtualDub, MSpaint, and batch or AVIsynty scripts) can become extremely useful when dealing with problems such as a capture program such as Camstudio not allowing screencapturing its own video options menu.
There are other FOSS(free and open source) screencapturing programs, but that will be a left for a future blog post.
For now, learning that VirtualDub will only append equally formatted video files together(this includes the audio bit depth and sampling frequency) is more than enough.
By the way, recording at a faster sampling rate(AKA frequency) and changing the audio to a lower sampling rate, will turn the sound graver, whilst the contrary, that is from a slower sampling rate (i.e. 44.1Khz) to a faster sampling rate (i.e. 96Khz) will create an acuter sound. Thankfully I dealt with silence on those parts, as the narration is appended later in the post-processing of the video.
