Hi, Does anyone know of a good tutorial on how to do this? Especially syncing audio properly. I would LOVE to be able to lay some better quality audio down over some videos, but every time I have attempted this the audio has been out of sync, and shuffling audio by ms until correct does my head in. Maybe there is an easier method that I am missing? Thanks.
Try Handbrake https://handbrake.fr/ One of HandBrake’s strengths is its ability to open a wide variety of video formats. HandBrake uses FFmpeg under the hood and generally can open whatever FFmpeg will, in addition to disc-based formats like DVD and Blu-ray. Note: HandBrake does not defeat or circumvent copy protection of any kind. It does not work with video files employing Digital Rights Management (DRM). See About HandBrake for more information about what HandBrake does and does not. https://handbrake.fr/docs/en/1.2.0/technical/source-formats.html or try MKVToolNix https://mkvtoolnix.download/
Hey, Thanks for the reply. It's not the muxing that's the problem, or copy protection I'm having trouble with though. It's the new (better) audio that I am trying to replace is out of sync with the video file.
Hello, there was a tutorial on a private tracker, all I can remember is that there was a software where you could load both audios an see their waveforms so that you could adjust the new audio to match the old one based on waveform. This was 12 years ago and I no longer have an active account there. if anyone knows which software has this feature to let us visualize and then cut/shift accordingly without reconverting the audio file please let us know
P.S.: I don't think this should be too difficult, there are already lots of vhs rips with replaced audio tracks and with perfect sync. Searched a bit on reddit, there are some programs which help you sync two or more audio files but the question is if those apps could handle ac-3/pcm formats and let you save your new audio as wav or flac
Import the vob into Audacity to see its original audio, then import the new audio below it, and move the new audio around or chop up the intro silence enough to sync them.
i use Adobe Audition to do this kind of work. it is a little snazzier than Audacity which i have also used. you can lay the tracks on top of each other to see how they compare, and align their starting points; Audition can snap one to the other's position. sometimes you have to chop sections out of the new audio if you can't find the exact video edit they used; Audition is a lot easier for this i've found, enabling you to blend and do micro crossfades and such.
