FFmpeg: Extract Audio from Video, Edit and Reinsert

In this video, I extract an audio track from a video file using FFmpeg. Then I edit the audio in Audacity. Finally, I use "map" to combined the new audio with the original video.

My neighbour asked me if it was possible to “copy her wedding tape to bvd" (bvd isn’t a typo) she wanted to surprise her husband for there silver anniversary. I said I would do it, it turned out was just filmed by a guest at there wedding on the really cheap vhs-c camcorder, the video quality was dreadful and the sound even worse.
I captured it, in 720p and 1080p the 1080p copy was horrid and far worse looking than the 720p. The sound volume was low it also suffered with wind nose and other interference I found the audio filters in ffmpeg really good, run it through low and hi filters and increased the volume all from command line without the need to export to external apps.
(I know you properly know this but others watching the video might not)

I appreciate you sharing this. I haven't delved into audio filters much in FFmpeg. It is pretty amazing what FFmpeg is capable of. I tested a couple of compositing input techniques a while back. I found a composite to HDMI adapter plugged into an Elgato Game Capture gave me the best video quality. That isn't exactly a cheap option if you don't have an HDMI capture device. It also doesn't matter much if the source video is bad. ua-cam.com/video/tsgD3x1N2KI/v-deo.html I have a cheap HDMI capture device coming in the next few days. It will be interesting to compare it to my Elgato.

RickMakes I’ve very very lucky about 15 years ago I bought my self a Panasonic dvd recorder. It was really expensive.
I thought it was good but it was until 5 years ago I didn’t realise how good it actually was it has
component
Composite
Scart (rgb) (Sorry you guys in North America missed out on this)
DVI/FireWire
S-video
I just use this to convert to hdmi, the dvdr allows me to select what I want out putted from 480i all the way through to 1080p in pal or ntsc-m or j.
I couple this is a avermedia stand alone pvr and it will capture up to 1080 at 60fps.
About 12 months ago I finally finished my converting 35 years worth of home movies on vhs, video8, digital8 and dv to a digital format. Having the stand alone way of capturing was a blessing as I could then trim, adjust and compress to x264 (now x265) while capturing more footage.
Ffmpeg is such a good tool what it can do is vast, I think the reason I like it so much as I grew up with dos.
