Of course you are...
So how many movie length x265 encodes to you do ??
And I'm sure as hell happy I don't have to pay your power bill !!!!
Just imagine how much time (and money) you would save it RB didn't spend so much time gathering information & indexing & demuxing & remuxing, it would be nearly an hour per job.
For example, if I had a Job Queue that had multiple x265 jobs, and I set it going, it would take approx 30 minute before it would even think about encoding, then a day later (if you're lucky), it would then take approx another 30 minutes to mux it all back together, then on the next job....same again, so over several jobs, hours have been wasted doing nothing
Like I said in a previous post, MKVToolNix does it's job in minutes, admittedly there's no DE, or filtering, but if the movie quality is good, (and most 4K movie's are), why does RB have to pull it apart, and put it back together. That's what takes all the time (other than the encoding), and why that has to take so long, when the file is already "up to scratch".
