Error (19) while trying to boost volume of video

[FubarTheInsane]

I am trying to boost the volume on my .mp4 video too and I've followed the instructions in this thread however when I click start to convert it gives me an 'Error (19)'. When I play the video that's created, the volume completely cuts off halfway through. Any help offered would be much appreciated!

It's not entirely clear which 'instructions' you followed since there is more than one possible scenario in the thread you linked to. Specify what you did.

Like, for example, what the hell program gave you an error (19)?

Did you try searching for what error 19 on whatever the hell program it was means?

What is the video/audio format of the input file? 'mp4' is just a container. It doesn't actually tell you what the format or codec is. Many formats can have a .mp4 extension. Use mediainfo.

Sorry I'm using MediaCoder (0.8.26.5566). Container is MPEG-4. Video codec is AVC1. See screenshot for more info. Is there any other info which would help?
