This is my first post question. I am familiar with NLE (Adobe Premiere, Final Cut Pro, Sony Vegas). I want to work in Linux Ubuntu, use Kdenlive and promote it. I am making a HD video. Video+Audio (1) was recorded on a webcam and I recorded a separate sound track with Audacity. Video+Audio (1) on timeline, audio waveform doesn't show. I have tried the show audio thumbnails button, bottom right and top menu bar Timeline/Show audio thumbnails clicking on an off and it doesn't work.
I have tried menubar Settings/Configure Kdenlive/Display/Thumbnails/Audio [tick] on and off. still doesn't work.
I have searched Google to no avail. What do I do, to see the audio waveform so I can sync up the sound?
