Like Tomovo above already said; your workflow would benefit from using an intermediate format that is faster to encode. You can then automate the conversion to the output format to occur unattended at a more convenient time. The use of intermediate formats is a well proven technique in video editing where encoding real time to AVC/HEVC at high quality is not possible. Codecs like ProRes are used that are much easier to encode to at the expense of storage space.
