1. A method comprising:
receiving, by a computing device, a video stream;
encoding the video stream to generate a first encoded video at a first bit rate; and
encoding the video stream to generate a second encoded video at a second bit rate, wherein:
a first plurality of intra-coded frames in the first encoded video is aligned with a corresponding first plurality of intra-coded frames in the second encoded video, and
at least one intra-coded frame in the first encoded video is aligned with a corresponding non-intra-coded frame in the second encoded video.
