I'm trying unsuccessfully to insert a PAL VHS audio RIP into a Blu-Ray RIP of the same movie. The PAL source is 25fps so the ripped audio from that VHS is 25fps too.
Now, when I try to put this alternate audio dub into the Blu-Ray movie of the same film, the sound never matches up and I've been racking my brains for years to achieve
this result but to no avail. All Blu-Ray's seem to be 23.976024 fps. I've tried converting my uncut original audio track from 25 fps to 24 fps and to 23.976 fps to match the Blu-Ray but it simply does not and after about 30 seconds it lags and falls behind or goes ahead of the Blu-Ray causing me a massive headache. I have tried everything. I have tried converting the Blu-Ray from 23.976 to 24fps and 25fps to see if that works but it is the same. And I have tried converting my VHS PAL video from 25fps to 24fps and 23.976fps all to no avail, also. The audio WILL NOT match up with my Blu-Ray no matter what I do and it's so frustrating. Please help me to understand/fix this annoying issue of mine. There must be a simple program I can use to convert and get the VHS audio matching the Blu-Ray. I came across similar questions on this site whilst searching for help on this and you all seem to know what the best free programs are for me to achieve this so I'm hoping someone on here can help me. PLEASE HELP!!!
P.S I also need to know if there is a simple video editor that will closely match the crisp BluRay colour of a film to an older VHS of that same film
just by putting them both together so it gives you the best colours to get it closely to match and vice versa? Is there an easy way to do this with a
free video editor? The colour of the VHS is darker in tone than the crisp brightly coloured BluRay and I need them to match as close as possible.
What is also the best free program to convert a VHS version of a film in 25fps to BluRay by closely matching the colour and same framerates so
that my audio still matches? I've been working for years in my spare time doing this but always run into a brick wall and I want to get it completed.

clever FFmpeg-GUI. Load your PAL VHS Audio (from 25.fps source), select audio modify, in "Change Audio Lenght" insert 25 as source fps and 23.976 as target , set "Lenght and pitch", set as output wav (for uncompressed audio) and convert the audio. Then in the multiplex section load your BR-Rip Video as video and the new created audio as audio and mux them. If in synch, convert the new wav audio to aac or ac3 (your choice) and mux this with your BR-Rip Video.
You can control sync with VLC Player and eventually find the correct audio delay.
Logically, the video content must be the same.
For example, if one film is the normal version and the other a special edition (e.g. directors cut, or similar), then the audio track may not match.

I will try this Thanks. if all else fails are there other easier methods around?
theundertaker180, find out the framecount for both sources. If not identical, it can't be done just by stretching and delaying the audio (unless the difference is only at the very beginning with different logos before the film begins). And if the framecounts are different - as they surely are - you'd have to find all the places where one version is different from the other and either add or remove audio. This is not an easy project and I suggest you give up.
Re-encoding your source will reduce quality, especially if you don't kow what your're doing. Haven't you heard of lossy final delivery formats?

The best way to do this is to ignore frame rates. Find an audio event near the start of the video, then another near the end of the video. Stretch/shrink the audio so that the time between those two events match. Then add an advance or delay so that the first events are in sync. But don't be surprised if even that doesn't work because releases in different countries are often different cuts of the movie.
just keep the FPS, SD on Bluray do that too
I managed to try a tool called TFM AUDIO and with this I was able to change the VHS PAL audio from 25 FPS
to 23.967 FPS and after joining them together, I pleased to say that the audio now matches the 23.967 BluRay
without lagging or overtaking. It was very simple to use and just what I was looking for. Now I'm looking forward to
editing the films together to include my ultra rare uncut audio to an amazing BluRay copy.
