I am so happy you enjoyed the BTS truck video.
We don't use Resolume for Broadcast TV – I have been doing this for 40+ years – from way before personal computers/small workstations could handle video, much less broadcast-quality video.
I am certainly very impressed at what the genius gurus at Resolume have done with their software, and my comments here don't mean to take away from their great accomplishment.
If you can tour a high-end, broadcast TV studio in your area while they are doing anything LIVE, you will hardly see Macs and PCs – except maybe the HUMAN INTERFACE on some devices to 'trigger' and control higher-end machines in the machine rooms. The reason? When it is LIVE, we need instant push-button access for everything – we hardly have time to move a mouse, use pull-down menus, load files, etc. Everything has to be INSTANTLY available in less than 1 second. That is why the server used to record multiple cameras and "cheat" instant replay in sports costs $200,000 – it is nicknamed "ELVIS" because the product is called EVS, and it is a 'glorified TiVO.' Often when you watch an awards show like The Oscars® – we cheat those shots because, say Zoltan here won an Academy Award® just as his name was announced. The director then cuts to him in the audience looking shocked, hugging the person next to him, then standing to walk up to the stage to get his 'Golden Boy' statuette. While Zoltan is giving his thank you speech, maybe Steven Spielberg is sitting there and giving a 'thumbs up,' but the Director and Producer missed that shot and didn't punch-it up on-the-air, so the viewer at home just sees Zoltan at the microphone giving his speech thanking Spielberg.
So all we do is go on the P/L (Production Line, the $100,000 intercom system) and tell the EVS operator to re-cue Spielberg on camera just 1-second before he lifts his hand to gesture 'thumbs up' to Zoltan on stage. The Director says, "Stand-by to ROLL and TAKE 'GREEN'" (we used to give each machine a number, like VTR 27, but that takes too long to say repeatedly, so we started in the 90s giving each machine colors, so EVS Channel 1 would be RED, Ch 2 would be BLUE, Ch 3 with Super-Slomo High Frame Rate would be GOLD, etc). The EVS Operator feeds the Spielberg clip to GREEN, and waits for the Director, who a moment later barks, "ROLL GREEN, TAKE GREEN!" The TD: Technical Director cuts to the EVS and you see Spielberg lift his hand to give a thumbs up, then cuts back to Camera 2 which is Zolton on stage. YOU THOUGHT THIS WAS ALL REAL-TIME LIVE, but it actually happened 35 seconds ago... no different than an instant replay for a football game.
Before the Avid Media Composer could do 'broadcast-quality' around 2003 (it was invented in 1994/95, but was only VHS poor quality for Off-Line editing to do drafts), we had to use VTRs (averaging $100k each) and edit LINEARLY, in the order a show would be. We had to always fast-forward or rewind tape to find the sections we needed.
I still teach Linear editing, and people who start there and then go to a Non-Linear/Mouse-windows based editing are much better editors because they really have to think before doing an edit, because mistakes or guesses waste a lot of time.
Watch the first 9-minutes of this kids show from the late 1970s that on their last episode, showed how they made the show in editing. While the quality is poor because it is a 2nd generation copy (VHS) from a Betamax home/consumer VCR, I remember it well as it aired and the picture was absolutely perfect and sharp – because it came from $120,000 2-inch Quadruplex VTRs (that is like spending $488,000 in 2020 dollars, adjusted for inflation). 2-inch Quad was the first video format invented in America by Ampex in 1956 and was used for 30 years (until 1985). Sony's 3/4-inch cassette (invented 1971) which had sub-standard quality in the beginning and made more for schools and training video, got better and by 1977~1980 replaced 16mm film for News crews, inventing the term ENG: Electronic News Gathering. Until the 3/4-inch format, you couldn't broadcast portable video – everything oustide on location was usually film, because of the size of 2-inch machines (about 2-3 refrigerators in size).
