Concert video with GH2 and Lumix 20mm

Here is an example concert video recorded using the Panasonic Lumix GH2, and the Lumix G 20mm f/1.7 lens. I recorded the movie in 1080i, 50fps. However, it was scaled down to 720p, 25fps before uploading to YouTube.

I recorded by pressing the red video button on the top camera plate. This gives automatic handling of most imaging parameters. Sadly, these parameters are not visible during video recording, so it is not possible to see what aperture, ISO, and shutter speed the camera has chosen. However, since this was recorded during dim light, it is natural to guess that the aperture was the maximum, f/1.7. The shutter was probably around 1/60 second, and I guess the ISO was around 1600.

One difference between the GH1 and the GH2 is that the latter supports manually adjusting the microphone recording levels. In this video, I let the camera set the levels automatically, which worked well. I think the sound quality is good.

I used the free software Openshot to edit the video. The editing in this case was limited to cutting off the start and end, as well as the downscaling to 720p.¨

The camera was handheld. To get some more stability, I had the strap around my neck, and rested my hands on the camera. By using the tiltable LCD display, I can record the video without getting much attention at all.

Compared with a similar recording using the GH1 and the Lumix 20mm lens outdoors, this camera manages to keep the focus pretty well throughout the video recording.

The band is the Frank Znort Quartet, playing "Mink Schmink".


  1. How did you record 25p with GH2?

  2. Sorry, I was being sloppy. It was filmed in 50i, and then converted to 25p with Openshot.

    Thanks for pointing out the inconsistency!

  3. Nice audio from that concert. My assessment is that the GH2's 4-level manual gain has varying degrees of limiters. Not confirmed, but my tests with numerous mics indicate that possibility.

  4. Thanks for your comment.

    I am not familiar enough with digital audio to comment your assessment.
