> I couldn't use my Canon SLR to record more than 30 minutes of video continuously
Large sensors optimized for still photography overheat when operating continuously for video, so they feature safety limits. Sensor heat dissipation is a big problem and a major differentiating feature of top end cinema cameras.
My Sony doesn’t have this length limit, but will readily overheat and turn off after several minutes of highest-bitrate recording. So no, overheating is trivially protected against via temperature sensors, not some arbitrary timeout.
