My full review of the Panasonic GH4 (final retail unit) is coming next week. Until then I am enjoying Philip Bloom’s views on the camera here!

A big thanks to B&H Photo & Video in the US for shipping internationally a GH4 unit with no recording limits, I got it before it was even available in Europe. Delivery took just 2 days! Impressed! Also thanks to Susanna, the star of my video above shot in Berlin.

A few days ago Thomas Worth of Rarevision (5DToRGB and RAWMagic) asked me for some original files from the GH4 so he could develop an experimental app he had in mind. The result is an embryonic new command-line app for the Mac, which takes 8bit 4:2:0 4K H.264 files from the GH4 and resamples them to 10bit 4:4:4 in 2K DPX format.

The GH4′s internally recorded 4K files can be converted to a chunky 2K 10bit ProRes 4444 image which grades extremely well.

To test this theory I call on colourists to have a go at it.

Arri Alexa ProRes files are available from their FTP server. Details below.

Andrew Reid shoots KineRAW MINI

Thanks to Michel and Ludwig at HD Videoshop in Berlin for the test unit. Essential primer details on the MINI are here.

The KineRAW Mini is a very cool option in the emerging raw market. With an almost identical range of features and the same 4K Super 35mm CMOS sensor found in the larger, more expensive KineRAW S35, this baby version has a form factor I absolutely love. It is not just small but light as well – very suited to the kind of art-film-on-location shoots I love.

EOSHD takes a brief hands-on look at what the camera offers.

The spec sheet is impressive. 14bit linear bayer raw is sub-sampled from a 6K sensor, giving 1280 lines of extremely clean resolution with an anamorphic compliant 4:3 aspect ratio.

This is in a similar league to the image quality of the Sony F35 (Superman Returns, Tim Burton’s Alice In Wonderland) which cost $250,000 just 5 years ago.
