In the unlikely case of you not finding a setting with a horizontal resolution of 480, choose the one with the next higher setting. In the screenshot, the vertical resolution is 480, but it could be different if your screen aspect ratio is not 16:9, and that is ok. Note 4 : A horizontal resolution of at least about 480p is required. Other options here use GPU, which reduces the load on CPU, but the file size will be larger. It uses CPU*, but compresses more efficiently. If your recording is terminated ungracefully, MP4 file will be unusable. The recording should not take more than a few 100s of MBs, but the performance will suffer if your drive/partition is close to full. Note 1 : Make sure your drive/partition corresponding to the path has at least 3-4 GB of space left.
