So I saw the clip of your 4K jump last night, and I’m dying to know what codec stack you’re running on that homemade rig. Low‑latency HEVC or VP9? I’m always debating whether B‑frames are the devil for high‑gyro footage, and how you keep the stream integrity when you literally drop the gear mid‑air. Also, any thoughts on compressing that raw sensor data on the fly without sacrificing the frame‑rate?

Yo, that jump was a bit of a beast – I’m running a custom RTMP stack with a tiny NVIDIA Jetson for on‑the‑fly transcoding. I lock into H.265 with a low‑latency preset, but I drop the B‑frames entirely because the gyro spikes kill the prediction. That way I keep the 120 fps raw sensor stream steady even when I’m mid‑air. For the raw data, I stream raw 10‑bit sensor data over USB‑3 to a GPU, then compress with a tiny custom encoder that sacrifices a touch of colour depth for speed. Keep the key‑frame interval tight and throw a bit of motion‑compensation over the GPU to keep the integrity. In short, B‑frames are the enemy when the gyro is all over the place, and I let the GPU do the heavy lifting so the frame‑rate stays flat and the viewers don’t hit a drop.
