Keyframe alignment for encoding video at multiple bitrates

In one embodiment, a method includes: retrieving information for frame type decisions made by a first encoding process when encoding a video at a first bitrate to generate a first encoded video; while performing a second encoding process to encode the video at a second bitrate to generate a second encoded video, performing: determining a frame type decision from the information for frame type decisions, wherein the frame type decision comprises a frame type of a frame for the video that was encoded at the first bitrate; inserting a keyframe in the second encoded video based on the frame type decision, wherein the inserted keyframe in the second encoded video is aligned with a corresponding keyframe in the first encoded video; and continuing to retrieve frame type decisions and inserting keyframes in the second encoded video until the video is encoded at the second bitrate.
