About "Skipping Identical Frames" on Eac3to?

[theliver9x]

Sometimes I get the message "Skipping identical DTS or AC3 frames (seamless branching).
That means it removed some frames from the original disc. So does it cause loss of original movie data and I am very worried that the software will cause the movie to lose some images making it not full content like the original movie that the producer made.
Can anyone explain this to me. Thanks.

Audio frames are groups of digital-audio samples.

(Yes, the tech terminology sucks, the "pros" love to be unimaginative and prefer adding new meanings to old words -_-)

Therefore, no, eac3to doesn't remove images from the video streams.
BUT the removal of audio frames MAY cause loss of synchronization,
generally speaking,
but I admit that I have no experience with seamless branching :-/

No, the point of removing the audio frames is to maintain sync for seamless branching.

Thanks for erasing the part that says that I might be wrong.

This is how multiple M2TS files are generated: the cut is exact in video frames, but it cannot be exact in audio frames at the same time.

Therefore, audio frames are repeated at the end of one M2TS file and the beginning of the next, compensated for by timestamps, and these must be removed to generate complete audio while maintaining synchronization.

Yes, exactly what I said.

Of course, I just wanted to explain the reason.

Got it, thank you.
