Audio boost on video

[Jawloms]

Morning,

 

Wasn't sure which forum to put this in, mods - feel free to move.

 

We have a Quicktime video recorded by the vicar we want to show our students at tutor time. It is ridiculously quiet! We've got classrooms on full volume everything and you still can hardly hear it at the back. Anyone know of a free, simple to use bit of software I can use to boost it please?

 

Thank you

 

Stuart

You can set your volume above 100% with VLC Media Player.

 

You could also try re-encoding the video with Handbrake, that has a volume adjustment option.

Open source video editor Shotcut has got audio normalisation; may be worth a look.

 

edit: Be careful with Normalisation, as it boosts *all* audio, including hiss and room noise.

I downloaded Handbrake and put the gain up full and saved it, then still had to do it again!

 

Sorted now though, thank you.

Depends on how long the video is... and how quickly you need it...

 

Back in the day if ever I wanted to 'acquire' some audio from a video for free, I used Audacity (it does require a specific setting in your soundcard though - if you can enable your input device to something like 'Stereo Mix') then you can just set that to record whilst playing the video.

 

Then you'd need to use Audacity to 'Amplify' the audio and export it, recode the video with that audio track and get it in sync...

 

Hmmmm... that's a lot of hassle actually....

 

Actually, you know what? Never mind... go with the option @Garacesh proposed.
