Fastest way to export video

Say you have around 30-40 videos, about 5 to 10 minutes each.
They are all encoded in a similar format, but not with the same exact properties (bitrate, etc...)

The goal is to concatenate them and to export the timeline, without adding any effects whatsoever.

Does anyone know what render settings to use, to make this render as fast as possible ?

Thanks

Mac or PC? If Mac, Apple silicon?

How will the export be used?

FFMpeg

You can give it timecodes of just the bits you want to keep. It won't re-encode, so it only takes a few seconds.
