Example video capture, GH1+Lumix 20mm

Here is an example video recorded without using a tripod, using the Panasonic Lumix GH1, and the Lumix 20mm f/1.7 pancake lens.



And a larger version of the same video:



As you can see in the video, the focus is hunting a bit back and forth. This could be due to selecting spot autofocus and the smallest focus area. Perhaps it would have been more calm using multi area focus.

Also, in this case I am using the camera firmware v1.2. The new firmware v1.3 available on May 10th, 2010 is said to improve autofocus performance during video recording, and may have solved this focus hunt problem.

When using video mode on the GH1, the camera will focus continuously, even if the focus selector is set in AFS. According to my knowledge, there is no mode that allows for autofocus when starting the recording, but keeps the focus constant when filming. I think this is a drawback with the camera. It is of course possible to select AFS, pre-focus, and then set MF before starting the video recording. But this is a somewhat awkward procedure.

The recording was done with the AVCHD format, at 720p and 50fps. My version of the camera is PAL, hence I am not able to record in 60fps. I used HandBrake to convert the stream to H.264, which is better suited for uploading.

The image is also a bit jerky, but I can only blame myself for not keeping the camera stable.

The video was recorded in Gamla Stan, Stockholm, Sweden. The musicians are singing "Dina ögon är som knivar", a Vladimir Vysotskij song translated to Swedish. The band is called Carl Oscar Nygrens kalas och nöjesorkester.
