Here some information about what I use to make the videos for the podcast.

recording

camcorder

To record my videos I use a Panasonic HC-V707EG-K. It was one of the first to offer 50 fps at 1080p. It's not bad, but lacks a couple of things:

  • no headphone connector
  • no manual focus ring
  • 60 fps only for the US model
  • no remote control or connection for a remote
  • the external microphone recording is sometime very noisy

For the audio I have Audio-Technica ATR3350 omnidirectional condenser lavalier microphone. But when plugged in the camera it generates a lot of noise in the background. I could not figure the cause, but it prevents me to get better audio recording. And the camera built-in microphones aren't too bad.

screencast

To record the screen I use SimpleScreenRecorder. It's simple and does the job well.

The audio is recorded using a Samson C01U USB microphone.

editing

video

Currently I am using blender to make my videos. Most know it for its 3D modelling, but it can also do video editing. It is slick (I avoid software bigger than 100 MB), stable, and does the job quite well.

I tried several non-linear video-editors:

  • I started with Kdenlive (v0.9.10). But it crashes to often, it has to be restarted because some actions can't be performed in the timeline for unknown reasons. What made me change was the speed video effect. It does not stack with the rotate effect, and it does not work correctly (it uses video before the beginning of the video part, and does no go until the end)
  • Pitivi freezes when I open a folder with H265 videos, and does not provide speed control.
  • Lightworks (v12.0) does not work. I shows a empty screen in Linux Arch.
  • Shotcut does not provide speed control.
  • Cinelerra does not support a lot of input media. But I would like to test it further.
  • Blender does not provide Motion-Compensated Frame Interpolation. This means that the input video frame rate has to match the project frame rate, else it gets unsynchronized.

To encode the video before and after editing I use ffmpeg. It does a good job at transcoding videos. And for the final video packaging I use mkvtoolnix.

audio

Audacity does the job well and provides a nice noise removal function. But it does not provide a command line interface and can not be scripted.

SoX is small and fully scriptable. It's noise reduction is not very good, but the rest works well.

subtitles

To make subtitles I use Aegisub. On the first pass I transcribe the video with approximate timing, only using the keyboard. I correct the timing with the mouse on the second pass.

work flow

To help me making videos, I have a bunch of scripts which do all sorts of side tasks:

  • compress the raw recordings
  • clean the audio
  • render the video
  • extract the chapter marks
  • export the transcript
  • package the final video
  • create a torrent
  • upload to my server
  • upload to youtube

But I correct and extend them for each new episode.

I just have to make the recordings, put them together, transcribe the the audio, run the scripts, and finally click on the publish button.
