x264 encoded streams have the original encoding parameters included by default.

  Encoding settings metatag can be striped. Regardless, I don't think these software are "matching" anything. TMPGEnc for example has settings to choose what quality you want for these re-encoded frames.

    The parameters being matched would be those that maintain decoder config. Usually, bitrate/quantizer values don't come into that.

      Oh yeah, the level would (should) definitely be kept.
