I have a mkv hdtv video that was encoded at 25fps but will not play on my Sony Bdp-s301 when I convert the video to Avchd.
So I adjust the settings in Tsmuxer to change the frames p/s to 24 and it now plays but the audio is out of sync.
What adjustment to the audio do I need to sync this video going from 25fps to 24, or even 23.967fps?
Thanks experts!

If you demux the 25fps audio and load it into BeSweet GUI, you can stretch it to 24.000 ('Change frame rate') or 23.976 (Presets)
The interface is odd, but you:
1 select the input file (it assumes the same path for output).
2 choose 'Change frame rate' or the Presets.
3 the output format
4 click ac3 to ac3
Then mux it back with the video.

I converted a two hour 5.1 AC3 stream through it twice without any failure.
The log reflects different versions of BeSweet and azid.dll from your own - don't know if it's relevant.

Ok, I was using the stable version, upgraded to the beta, newer version.
It worked in ac3 mode but, the file converted 5.1 to 2ch stereo.?
I have the "create 5.1 Ac3" checkbox selected under AC3/OGG/PCM, what am I doing wrong?
Thanks!

Program seems a little buggy at times when changing settings, you have to restart the program sometimes.
But I got the 5.1 (ac3 to ac3) fps change to work and it looks like a success!

Is there any pitch change going from 25fps to 23.976 with Besweet?
I heard its better to produce 6ch wav files with Besweet and convert to Ac3 with Soft Encode but apparently the program has been discontinued.

From what I have read, the -r is supposed to convert the framerate without changing the pitch.
"C:\Program Files\old_BeSweet\BeSweet.exe" -core( -input "C:\Documents and Settings\Superuser\Desktop\clip.wav" -output "C:\Documents and Settings\Superuser\Desktop\clip-New.wav" -2ch -logfilea "C:\Program Files\old_BeSweet\BeSweet.log" ) -ota( -r 25000 23976 -hybridgain )
Notwithstanding, I can hear a slight pitch change in this sample.
Compare the original to the BeSweet version.
Then the BeSweet version after it has been adjusted with Audacity.

So you use Audacity after besweet to adjust the pitch?
How about subtitles with .sup extension, how do you adjust the frame rate for those as well?

The latest release of Audacity can input/output AC3 files - so BeSweet can possibly be by-passed.
Load the original 25fps AC3 into Audacity, select Effect > Pitch and Tempo > Change Tempo and adjust by (25/23.976)*100 = 104.27093
Insert -4.27093 as the percentage change.
Re-drag the original audio in with the adjusted and compare the pitch.
In this sample, I used a wav file from an avi that was 63 seconds.
After adjustment it was 66 seconds (which matched the length of the video where I changed the frame rate using VirtualDub).
SubtitleCreator can adjust frame rate of sup/idx files.

I believe SubtitleCreator is for .sup from Dvd's.
BDSup2Sub is supposed to be from a Blu-Ray disc, like from the mkv I posted. Will give em a try...
Thanks

Audacity
How do I download and install the FFmpeg Import/Export Library?
Windows:
1. Download the FFmpeg installer (avformat-52.dll)
403 - Forbidden
Can't download the FFmpeg installer to import ac-3 files.?

Thats what I did, clicked download, it took me
to a website, when I tried to download the link,
I got the forbidden message
Ever try Besweet to convert ac-3 to 6 mono wav files, then Soft Encoder to convert to ac-3? Heard the quality is a lot better...
