How to film a BJJ round for useful feedback
Useful feedback starts with footage someone can follow. You do not need a polished highlight reel: a clear view of a round and a focused question are more useful.
Ask before you record
Check your gym’s recording rules and get permission from everyone who will appear. Explain where you intend to send the footage and who may see it. Permission to record does not automatically mean permission to share publicly. If someone does not agree, choose another round or camera position.
Keep both practitioners visible
Use a stable position outside the training area. A landscape view often gives you more room to keep both bodies in frame. Check the start position and leave space for movement. Keep the camera and its operator away from people training.
Check the actual recording
Record a short test and play it back. Check light, focus, and whether a person passing the camera blocks the view. Avoid relying on a digital zoom that makes grips and movement hard to see. Audio is optional for understanding the positions.
Keep the context around the moment
A submission or position change may begin before the obvious ending. Keep enough footage before and after the moment to understand the sequence. Note the timestamp and describe which practitioner you are.
Add one question
For example: “At 00:38, what should I pay attention to before my opponent changes position?” This is an illustrative question, not feedback from a customer. Keep the original clip so you can compare it with your notes later.
Personal feedback on your rounds
BJI is being built to connect your footage with a human reviewer, clear corrections, and a drill for your next session. Waitlist signup is free; reviews aren’t open yet.
