Replacing audio on older music videos ?

Hello all,

I collect music videos from the 70's, 80's and 90's and remaster them to the best of my ability.  I am looking at what Adobe product will do what I want in regards to replacing audio. I am presuming Adobe Audition, though I am wondering if Adobe Premiere is thew better option ? Regardless, as long as one does what I want I will be happy.

 

In most cases, when I go to replace the older usually poor audio on the video with a  newflac version, they dont match. Sometimes the original will be running faster, other times slower.

So I am trying to find out how to use Audition or Premiere to do this. I have done a lot of Googling and searching, and looked at many Youtube videos but none seem to cover what I want to do. Previously I used to use an old version of Filmora that allowed me to do it, but that version will not run on my new PC.

I do know from someone that he does it on Adobe Audition 3 and it involves stretching the audio file, but after a lot of trying I cant seem to find how to do it on a more modern version of Audition.

 

I am unsure if I should import the video file and new flac audio, or if I should take a copy of the audio from the video and use that and the new flac track. And more importantly, exactly what do I do from this point ? Obviously the new Flac file needs to be adjusted to be exactly the same as the original audio, otherwise it will be out of sync with the video.

 

Any tips or pointers very much appreciated.

Syncing the new audio with the old is, perhaps, the key, as you suggest!

 

I own and use Audition quite regularly but not Premiere so I have no idea whether the latter natively offers the facility you need! 

 

However, there is (non-Adobe) software specifically designed to sync two different "versions" of the same audio, Red Giant Plural Eyes  It is not particularly cheap to buy, but, IMO, it does a pretty remarkable job of fully aligning two versions of the same audio!  If you have Premiere, you will see from that linked page that PE and PPro apparently interface very easily

 

You might need to first convert your flac file to wav (Audition is ideal for that) but you would then place it and the original video file into the PE workspace and press Synchronize.  The software examines the files and "aligns" them (by adjusting in this case your "new" audio to exactly match the "old") and then you can have it create a new, time-aligned version of your wanted audio.

 

You then place the original video file and the "new" (aligned) audio file in your video editor of choice, mute the original audio and export a final version with the "old" video and the "new" audio.

 

The (manual) method you mention (time-stretching etc.) can and should achieve the same final result, but with much greater difficulty for the operator and at considerable expense of your time!

Sorry for the slow reply, I appreciate you both taking the time to reply to me.

I suppose I was curious as to whether there was just some one press option, and thought in this day and age that there would be. Unfortunately its on Red Giant Plural Eyes 🙂 Which is sadly a touch out of my budget, it would be perfect otherwise.

Euan, I didn't get notification of your reply so have just seen it, so will definately take a look. If Audition was the answer, I was looking for some clues on exactly where I should be in the program, so thank you for that and also to emmrecs.

 

Cheers

Hi,

I would suggest a workflow similar to this:

Take your old audio from the video into Audition. Place it on a track in the multitrack mode

On the next track down place the new audio.

Use the pitch shifter effect to change the speed of the new track to match the existing one.

See this video for some explanation: https://youtu.be/oFz3UDCpB4M

 

Best regards, Euan.

Re your comments on the YT clip:

Although I mentioned using the length of the track, you really do need to compare waveforms

especially if the original track is truncated.
Since the original track is degraded, you'll need to work on it in Audition

to make it look / sound better for comparison purposes.

Looking at your YT channel, you seem to do a lot of this, so it will save you enormous amounts

of time to tuse a product like Pluraleyes. Time is money they say.

 

Best regards, Euan.
