Am I missing the ball totally?

Using v29.1-60-gaf5d819671

I use mythtranscode and it just works outa-da-box.
For h264 I wrote a script that uses ffmpeg to recode the video. It takes MUCH longer.
To transcode an OTA movie with say 10 ad breaks takes say 20 secs.
I use ffmpeg to cut from an h264 then copy the streams. That may take 5 minutes.
Ummm I think I’m doing lossless. Am I wrong?

A real transcode. using shotcut takes 1/2 hour (4 cores at the endstop)
