Re: Kdenlive + Audacity noise reduction
I've done something like this with audacity, but not a good while to remember exactly how. Some 6-7 years ago I was excited about starting a business, and was playing with building a call IVR system that I recorded my own voice audio for voice prompts, but picked up the rest of crap in my house too. I used some basic noise filters through standard installed filters to remove stuff almost brainlessly. I remember a buddy of mine checking it out for me, he asked me if I did these professionally edited or something, and was just like "nah, me screwing around", but it ended up being really clean audio recording through my Jabra 510 speakerphone. For your use case with video, you'll probably need to extract the audio stream, run it through audacity with the noise filter, re-mux it back in. I don't deal with video editing really to tell you the best method there, but probably containerize it as a mkv. I'm sure you ought to be able to mux the audio/video feeds with existing tools, mostly what folks do with video all day for pira^H^H^H^Huploaded videos all day.

Re: Kdenlive + Audacity noise reduction
I was using an iPhone to record the Video. I wonder if that was contributing.

Re: Kdenlive + Audacity noise reduction
I've never had that problem. I actually do this for every video I've made for plug. I just use the export audio function from within kdenlive and then do whatever processing I need to do on it and then simply save it back out as a wav again (or more recently a flac file so save space) and load it into kdenlive, making sure to line the beginning of the audio clip up with the beginning of it's video. They've lined up every single time. You just have to make sure that you don't cut any parts out from either the video or the audio before reassembling them in kdenlive. That being said if you somehow did get your audio off, you'll need for look for some visual clue as to when things happen and simply slide the audio over until it lines up. I used to have to do this for every single plug video when I first started because I was capturing the audio completely separate from the video. Ideally you would use a clapperboard or just simply have someone on camera clap once so you could see the clap and line up the corresponding clap sound with the clap motion.

Kdenlive + Audacity noise reduction
All, I have a video that I want to reduce noise. I can extract the audio and cancell the noise via Audacity. However when I try to join it to the video clip in Kdenlive it is out of sync. I have looked and cannot find a solution for this. Any help would be appreciated.
