Blunty's Panasonic GH4 - 4K video test shoot



Blunty has shot the video with the Panasonic GH4 and Panasonic 15mm f/1.7 lens.

I've used GH3 and Olympus 17mm f/1.8 lens for creating videos before, and the noise at high ISO practically made my videos unusable.

So I'm shocked to see the high ISO performance of the GH4 in Blunty's video. It's just incredible, nothing short of amazing. There's noise, but it's so well controlled.

GH4 users have been floating around the idea of extracting an 8MP photo from the 4K video, and you will see in the video that even for those stills, the image quality is quite good.

Wow. This camera is very good.

Journey to the West exhibition opening (3 May 2014)

Here's a video shot handheld at an exhibition recently.

For this I used the GX7 and the Panasonic 14-45mm kit lens.

I've had the kit lens for years but this is the first time I'm using it. Never gotten around to selling it, but it proved to be very useful.



I had lent my friend the Panasonic 12-35mm and it's still not back yet. The 12mm is more useful indoors. The 14-45mm is the only other lens with image stabilization.

OIS is extremely useful when shooting handheld. Without it, I've no doubt most of the footage would be more jerky, especially towards the 45mm end.

The 14-45mm performed very well, in terms of clarity of the video. It was shot in 1080P. The noise performance is also quite good, noting that this lens actually starts at f/3.5.

I've turned off Autofocus during video mode, choosing instead to focus by half-pressing the shutter. Sometimes it's fast, sometimes not, but generally speaking it's acceptable. On hindsight, I should have practiced with manual focusing.

Time lapse of setting up the exhibition Journey to the West

This is the first time lapse video I made using the Panasonic GX7.

The GX7 has an inbuilt intervalometer which is really convenient while making time lapse videos.

Setting up the intervalometer is also very easy. There are three things to set up, namely the start time of when you want to start, the number of shots you want to make, and the interval between each shot.

In the video below, I've set the interval to 2s, and the shutter speed to 1/10s.

To shoot a time lapse, you should use the manual mode. Set up the shutter speed and aperture you need, then adjust the ISO -- you can't have auto-ISO or the exposure will flicker. Also important to turn off image stabilisation on the lens and camera. I also use the silent shutter to reduce shutter shock and keep it quiet in the library.



In the video above, the first half was shot with the Olympus 9-18mm. You'll notice the jitter, some slight zoom-in and out, because I forgot to turn of the image stabilisation.

The second half of the video was shot the following day with the Panasonic 7-14mm. I had turned the stabilisation off after reviewing the first day's footage. The jittering is gone.

Generally speaking, a 2s interval for people is what I normally use. If you need more motion blur, just reduce the shutter speed to slower than 1/10s.

The upcoming GH4 will have an in-built intervalometer also.
