Ask HN: How do you produce product/feature demo videos?

I use the following on Linux to create things like this: https://vimeo.com/641668961

- OBS Studio to record video

- Google Sheets to keep track of different segments of the video

- ffmpeg to split the original video into separate chunks (one per 'scene')

- openshot to arrange the scenes into the full video (speeding up some scenes and maybe slowing down others)

- (don't remember) for recording voiceovers

- sox for normalizing volume of voiceovers

- openshot for adding the voiceovers in the right spots (with the help of my Google Sheet) and background music

Recently I've been learning kdenlive to edit videos. I believe it uses ffmpeg on the backend. It's been great! The open source tooling around video recording and editing actually seems fairly good.

Thanks for sharing your workflow on Linux :)

Love the video. How long did it take to make?

Once I had the raw video footage (single unedited file), it took me something like 5 hours to create the final video. Some of that time was recording/re-recording the voiceovers, writing some spreadsheet formulas to create ffmpeg command lines for splitting the video file, finding background music, and learning to use openshot (I'd never used it before).

I think something similar would take me 1-2 hours today, and half that time would be rewatching the video to decide what to adjust.
