This is this process of joining both the audio and sound together ready for broadcast or whatever source, be it for YouTube , terrestrial TV, on demand services or the big screen. The render time for this 16 minute project was just over 3 hours for a 1080p version.To put that in to context, it took us 4 minutes to render 16 minutes of audio at 24/48k,  roughly 4x real-time speed , compared to the render time for the video which was 11x slower than real-time. With such a long render time its something  you have to consider when approaching a deadline  , especially when you get an hour in the the render and the system glitches meaning you’ve just lost an hour.
