eac3to The Audio Delay Thread

[Colek]

Thanks but I don't get what the * means. What are the delay to apply?

Blade Runner has

42*41.7ms

And Dracula

24*41.7ms

I'm confused LOL shouldn't one of them be double if the first number is the frame differences ?

It's multiply sign - literally. Just multiply these two numbers and check with the code snip he gave You'll have your total delay in miliseconds.

Oh I get it. Yeah I read the delays, but was wondering what are those numbers. Thanks for Legend it'll help me get it done.

Hi Chewtobacca, i'm trying to sync some Predator original audio, and I have 7 frames of difference between the two masters.

The old BR @ 23.976 is 7 frames ahead ref frame is at 3027

The tracks I want to sync are from the first DVD @29.97 ref frame is at 3020

Second DVD open matte @23.976 ref frame is 2980

How do I convert those 7 frames in milliseconds?

And the 47 frames of the second.

Is 42ms one frame?

Then my account would be: 7x42 and 47x42?

Thanks if you can help.

How do I convert those 7 frames in milliseconds?

1000ms/23,976fps=41,71ms -> 41,71ms x 7frames = 291,97ms -> 292ms delay

7 frames:

Code:

eac3to input output +292ms

47 frames:

Code:

eac3to input output +1960ms

To sync the standard BD to the UHD BD, apply a delay.

Code:

eac3to input output -2002ms

Fistful of Dollars, A (1964)

This syncs the DE BD (00021.mpls) to the IT BD (00000.mpls).

Code:

eac3to input output -22981ms

(551frames)

Before remuxing, slow down the IT BD.

Just bought the Italian blu for the improved colours and a German one (cheaply!) for the lossless mono, so this was precisely what i needed. I'm happy to report that this works with just mkvmerge as well!

1. Load the Italian blu (ripped to mkv with makeMKV in my case) in MKVMerge, de-select the audio track (don't need it) select the video track and put default duration / FPS to 24000/1001p. Start multiplexing.
2. Load the German blu (ripped to mkv with makeMKV in my case) in MKVMerge, de-select the video track (don't need it),  select the audio track and put -22981 in delay (in ms). Make sure you put the minus (-) there as well. Start multiplexing. This will result in an .MKA file, which is fine.
3. Load the new, speed-improved Italian MKV and add the new MKA file. Start multiplexing.

Done! You should now have the the best of both versions.

Thank you very much Chewtobacca!

You're welcome. I'm glad that you found it useful.
