Panasonic GH3 72Mbps ALL-I Sample Movie
  • The website Photography Blog has published a 14 second sample move shot with the Panasonic GH3 in 72Mbps in ALL-I.

    http://www.photographyblog.com/previews/panasonic_gh3_photos/

    I have attached a screen shot taken from the movie. Unfortunately I am disappointed with the quality of the movie which I find inferior regarding sharpness and compression artefacts to driftwood's ALL-I hacks for the Panasonic GH2. Hopefully the 50Mbps IPB mode is better.

    Below is the specifications of the movie.

  • It looks like a typical video image quality from a few years back, sharpening is not too nice looking.

  • I think; it does not rain. There is very noise in the background!

  • hope it is due to high iso, it could be an excuse for the quality!
