here is some steps to save your time of exporting.
I am using Prores HQ for Editing. (You can choose your own compressor except H26h Codec).
1. Frist Convert all the footage in Prores HQ.
2. Make ur timeline Prores HQ for editing. If that timeline is very heavy for your system then change the timeline setting to prores proxy.
3. when you finish your editing, change again into prores HQ and render the full timeline.
4. After render finish make in an out and export (command+e for exporting in the default settings) into the same compressor.
5. When exporting is finish open that file into MPEG streamclip and convert your file whatever format you need. it will save your 2hrs time.
