Thanks Kurt, for the very interesting response.
Assembling videos
The problem for me is – being able to assemble video chapters into an evening's presentation, and have it look like you're in a cinema. We put on Classic Movies in our home theatre once a month for a group of friends, played from Blu-ray. The first half consists of newsreels, shorts, cigarette ads, and home movies. All these items have been exported from Premiere, and archived as blu-ray compliant m4v and m4a files. I've gathered thousands of them over the last 12 years. Come movie night, I decide which ones I want for that particular evening. If I'm showing All About Eve, for instance, the newsreels and cartoons will be chosen from 1950.
Encore (and Toast) can assemble an hour of Before-Interval video files in about 10 minutes, because I've archived those files as blu-ray compliant. No encoding is necessary, just assembling.
Like in a cinema
The friends turn up and it's just like in a cinema. There's a special menu on screen, with a button ready to start the show. No fooling around with computers and all the junk that comes with that, and all the possibilities of things going wrong (the mouse appears on screen, warnings crop up – "Keyboard battery flat", "Download in progress"). Whew. An endless supply of interference.
QLab?
The theatrical presentation software, QLab, lists pages of settings to change before a presentation. I think they even have a script that does most of it. I tried QLab. No good. It cannot assemble m4v files.
MP4, Quicktime, Oppo and Smart TVs
In hundreds of classic-movie nights, and dozens of public showings of my own AVs, the Oppo has never faulted playing a blu-ray disk or a blu-ray folder from USB. Never, no matter the bit rate. I've tried playing mp4 files and Quicktime files from the same player, and the video stutters.
I've tried playing a blu-ray disk from the Oppo with other people's Smart TVs. Works every time. But try playing the same presentation exported to mp4, using the Oppo or any of my Macs (playing from VLC or Quicktime Player), and the playback is unreliable, depending on the TV. Some TVs play reliably, most I've tried, don't. I'm talking high bit-rates here, above 30Mbps.
Mickey Mouse
So, for two reasons, mp4s and computers are not for me. There is always the hassle of the presentation looking mickey-mouse (all that computer junk appearing), or the playback is problematic. I've been there. I've tried it. It doesn't work. I want the feel of being in a cinema.
Blu-ray players do one thing superbly. Computers do lots of things, and some of those things are sub par.
Thus Encore > Blu-ray folder on USB > to Oppo BDP-93 > BenQ DLP projector. Works beautifully. Never had a hiccup in front of an audience.
Toast?
Toast 11 can also assemble video files. I can still present a seamless movie night, but during the assembling of the chapters and the final build to blu-ray folder, I have to use workarounds. That's okay. But because Toast only offers a Playlist for videos, and not a Timeline (Encore offers both) I cannot jump between chapters. If something does go wrong during a presentation from the Oppo (has never happened, mind you), I would have to revert to Top Menu, and fast forward to where I wanted to be. Not a good look in front of an audience.
I'm hoping someone who uses Toast 20 for blu-rays can run a few tests for me.
