Video adds about 500 kb/s. This is at the standard rate of HD491 and HD492 encoders, which send 1-5 frames per second. The frames are designed to clearly show on-screen graphics, but action will generally not look smooth at this frame rate. The compromise is intended to preserve reliable low-latency performance even on limited network connections. Note that the caption monitoring overlay seen by the transcriber is produced locally at up to 30 frames per second, and will scroll smoothly despite the limited video frame rate.
