The purpose of this guide is to catalog common errors you may face while transcoding/converting videos to .moflex for CTR with Mobiclip Multicore Encoder. Hopefully by the end, you will have successfully converted a video!

Each entry will consist of a description and solution(s) for the error. There may also be theoretical and/or untested methods worth looking into later.
