Recording day, by the numbers

Mamba Smith is the founder of Queen City Garage, which produces The Grand National Show: a weekly NASCAR panel show on Grand National Today where broadcasters and drivers argue about the last race and pick the winner of the next one.

Both editions of The Grand National Show recorded at 11 this morning. By the time I sat down to write this, the NASCAR O'Reilly Auto Parts Series show had a first master that passed 343 checks and the Truck Series show had a working cut. Here is what happens in the hours after a panel hangs up, with the numbers attached.

The pull

Everything comes down from Riverside, the remote studio we record on, through a logged-in browser: 12 video tracks and 6 transcripts across the two shows, about 8.5 gigabytes. Each file is filed under its episode with a checksum. Nothing is a source until its hash is on record. That is gate two, and it is the reason a corrupted download shows up as a mismatch on day one instead of a mystery on day three.

The two takes

The Truck show ran in two takes. In the second one, a panelist's feed dropped at 23 minutes 21 seconds, before the picks. A third take of 3 minutes 48 seconds brought him back for his pick and a second close. The decision was to run take two in full and use take three as a closing tag, so nothing anyone said was lost and the picks are complete. The compositor, the program that lays the camera feeds into the show's layouts, handles the stretch where he was gone with a three-person layout and returns to four when he does.

One of his tracks had come down at a slightly different frame rate from the others. It was conformed to match before it touched the timeline. A frame-rate mismatch is the kind of thing that looks fine for a minute and drifts for the other twenty-nine.

The first master

The O'Reilly show rendered from the 11 a.m. take at 27 minutes 27 seconds in a three-person layout, with the Burnout of the Week segment placed at 10:19. First quality pass by a person: four dead-air pauses trimmed, three moments where a panelist sat alone beside a driver card moved into the field layout so the card had company.

Then the checks. Version three passed 343 of them with none failing: sync within 30 milliseconds at every checkpoint, loudness on target throughout. The compositor was also rewritten today to work with any number of cameras rather than assuming four, which the Truck show's dropout made necessary about an hour after it was convenient.

The Truck master

Take two in full, take three as the closing tag: 30 minutes 44 seconds, four-person layout with the three-person fallback for the stretch the feed was down. Guest clips came from files the producer left on the desktop, plus seven race clips from the official highlights. The Kansas race details on the boards were confirmed against two same-day releases before they were rendered.

Both masters are held for review tonight. Nothing publishes on recording day.

What the day is for

A recording is raw material. The panel's part is done at noon. The rest of the day is turning four separate camera files and a transcript into something a viewer would choose to watch, and then proving, 343 times, that it holds together.

The person's part of that is taste: which pause to cut, where a card needs company, which take to run. The machine's part is everything that has to be true at every second of thirty minutes.

What a person did: chose the takes, trimmed the pauses, placed the segments, watched both cuts. What the machine did: pulled and hashed 8.5 gigabytes, conformed the odd frame rate, rendered both masters, ran 343 checks.
