The footage here is shot with the EOSHD Intra-esting patch (AVC Intra at 88Mbit), which you can download here. Edit in Premiere CS5.5 on an AVC-Intra timeline for best workflow performance.
Myth busting time! Yes the GH2 really can do clean, detailed ISO 12,800 in low light, and it is the best current DSLR for low light shooting, with an organic fine grain noise pattern like the Canon C300. How? It all depends on picture profiles, as EOSHD shows in this video tutorial.
