All of the proprietary tools I know of for doing frame-perfect cuts (VideoRedo, TMPGEnc, SolveigMM) work by determining (guessing?) the original encoding parameters and then only reencoding the first and last GOP. The rest of the video is just remuxed.

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.
