I have stayed up for finals and walked into class the next day with nothing useful to say. When a coach asked what I learned, the best I could offer was "that athlete was really good." Hours of footage, almost nothing in my hands. The problem was not the stream. It was that I chased highlights and never wrote anything down.
Hi, I am Quartz, building the jiu-jitsu journal app Post Black Belt. This is not a tournament prep checklist. You do not need to compete. Open a notebook while the stream runs. The same idea as the 4-line after-class journal, applied to competition footage: the smallest note that still changes next class.
Two Events Worth Studying This Season
Late 2026 stacks two big events close together. Both usually have solid live coverage and replays, which makes them easy to study from.
- Abu Dhabi World Professional Jiu-Jitsu Championship (professionals): November 19–21, 2026, Mubadala Arena. The broader championship runs November 9–21. Check the AJP Tour event page for the schedule.
- IBJJF World No-Gi Championship: December 10–12, 2026, Las Vegas Convention Center. Details are on the IBJJF event page.
Watching a gi major and a no-gi major in the same season makes grip changes easier to see. Even with no plan to compete, treating these two weeks as a study window is enough.
What to Watch For (Not Just Who Won)
The first instinct is to hunt submissions. That is fun, but the detail you can take to class usually sits just before the finish. I look for three things first.
- Grips before the pass: where the hands were — collar, sleeve, wrist. In no-gi, which came first: wrist, elbow, or head control.
- Where they put weight: shoulder or hip, knee on or off the mat. A clean pass is often weight placement more than force.
- What they do when stuck for three seconds: quit the direction, push once more, or change the angle. This is the part that looks most like your sparring.
The winner is already on the screen. What you need to write is why that exchange worked. One sequence is enough. You do not have to note the whole final.
The 4-Line Watch Template
Same shape as the after-class template. The subject just shifts from "I" to "they." When one exchange ends, pause and fill these four lines.
- Position: where the exchange starts — closed guard, half, standing.
- What they did: the sequence in technique names. Short is fine: "guard → knee slide → mount."
- Why it worked: one reason. They cleared the sleeve first, blocked the knee line, or the opponent stood up into a bad angle.
- Steal for next class: exactly one drillable thing. "Break the sleeve grip before entering the knee slide" is enough.
Here is what it looks like in practice.
- Position: closed guard, on top
- What they did: broke the sleeve grip, knee-slide passed, held mount
- Why it worked: clearing the sleeve first removed the heel-hook threat before the pass
- Steal for next class: drill breaking the sleeve grip before the knee-slide entry
Two or three four-line notes per video is plenty. Write more and you will not want to reread them. Same rule as the training journal: consistency beats polish.
After the Stream: Turn Notes into Next Class Focus
Notes pay off when they reach the next class. When the stream ends, collect only the last lines ("steal for next class"). Pick one as tomorrow's focus. Leave the rest for later.
Keep the names consistent too. If you write "knee slide" today and "push the knee through" tomorrow, you cannot group the same idea later. That is the same rule from the after-class journal. Fix technique and position names in your watch notes, and a month later you can see what you meant to steal that season at a glance.
Log It as a Short Diary Entry
On days I watch competition footage, I still write a short journal entry. Category can be freeform or something sparring-adjacent. Title gets the event name and date; content gets the four lines. Techniques I noticed become hashtags, so I can find them later under My Hashtags by area — guard, pass, submission.
For the exchanges that really clicked, I favorite the entry. By the end of the season I forget which notes mattered. Favorites give me a starting point for the next study cycle.
A notes app or a paper notebook is fine. If you want technique names collected as hashtags and grouped later the way I do, Post Black Belt can help.
FAQ
Can white belts learn from black belt matches?
Yes. Keep the steal small. Trying to copy a black belt's whole chain will not survive next class. Bring one frame — where the first grip goes, what they clear before a pass — and white-belt training can use it immediately.
Live stream or replay?
Replay is better for notes because you can pause and rewind. Use live for atmosphere and flow; do the study pass on a replay or highlight. If you only have time for one, one replayed match beats a whole night of live with no notes.
Should gi and no-gi notes look different?
The four-line structure stays the same. What changes are the words inside "what they did" and "why it worked." Gi notes fill up with collar, sleeve, and pant grips; no-gi notes lean on wrist control, underhooks, and head position. With World Pro and No-Gi Worlds in the same season, comparing similar positions under both rule sets starts to show what you can drop from your own game.

Pick one match this weekend. You do not need to finish the whole card. One exchange, four lines, and you will walk into the next class with something to try. If you have feedback about the app, feel free to share it anytime. 😇
