It all went smoothly. I used G3 lav for speaker audio and Sony PCM-M10 to record ambient sound and questions. HF G20 used to shoot slides, G7 with 12-35 f2.8 lens to film audience, GH4 with 35-100 f2.8 lens to film the speaker.
Here is my post workflow:
- Copy all the footage into editing workstation.
- Import the footage into Sony Vegas Pro. Work around Sony bug of importing Panasonic footage.
- Sync all the tracks. I do it by waveform. HF G20 requires adding extra frame of silence between MTS files. Sony PCM M10 is typically skewed tward faster clock so requries added silence (fraction of a sec) as well.
- Do multi-track editing.
- For all video tracks: add these filters: white balance, brightness and contrast, levels. Set those using reference card footage I captured during production and color correction GUI. Sometimes this does not work - e.g. G20 footage can look so different I use color match filter instead for just G20 track.
- For all audio tracks: add compression.
- Add credits, lower thirds, etc
- Render for YouTube
