    Hi there,

    Yes, you have corresponding keyframes with the same time stamp for streams 1-4 which means keyframes are aligned.
    The difference between pts and dts is not the concern. The concern is that for each video in your multibitrate stream, the corresponding keyframes have the same timestamp.
