- tialaramex 7y agoYou can defeat this for VoIP by using a codec in CBR (Constant Bitrate) mode. You should look for this feature in secure audio software. Unfortunately for video CBR is generally thought to be too expensive to be acceptable. 50kbps CBR Opus wastes 22Mbytes of data in an hour if you're silent compared to a good VBR codec. A small price to pay for improved security. But a CBR Netflix encoding might move several gigabytes per hour of extra data compared to a visually similar VBR encoding, and that's going to really hurt both Netflix and quota restricted customers.
