Henry Gentles Posted January 18, 2014 Share Posted January 18, 2014 Found this mock up comparison, thought some might be interested. http://wolfcrow.com/blog/a-fun-comparison-between-the-late-blackmagic-production-camera-4k-and-the-rumored-panasonic-gh4-4k-camera/ matt2491 1 Quote Link to comment Share on other sites More sharing options...
Guest Posted January 20, 2014 Share Posted January 20, 2014 "the best data rate from the GH4 is 25 MB/s at 30p" WTF? Quote Link to comment Share on other sites More sharing options...
tosvus Posted January 20, 2014 Share Posted January 20, 2014 "the best data rate from the GH4 is 25 MB/s at 30p" WTF? about right. MegaBytes, not megabits, hence upper case MB Quote Link to comment Share on other sites More sharing options...
Guest Posted January 20, 2014 Share Posted January 20, 2014 about right. MegaBytes, not megabits, hence upper case MB Ah yes, thanks. That also makes the Production camera bitrate HUGE! (I'm used to H264 and avchd) Quote Link to comment Share on other sites More sharing options...
Julian Posted January 20, 2014 Share Posted January 20, 2014 The biggest point is missing: the BlackMagic is a video camera, the Panasonic is a Hybrid Stills/video cam... Quote Link to comment Share on other sites More sharing options...
HurtinMinorKey Posted January 20, 2014 Share Posted January 20, 2014 The article says that Thunderbolt can only capture HD, and not 4K. How is that possible? Thunderbolt has plenty of throughput. Plus, if it can capture raw from the BMCC, it should be able to capture 4K compressed. Quote Link to comment Share on other sites More sharing options...
odie Posted January 20, 2014 Share Posted January 20, 2014 for 4k…has the 5d mark 3 become obsolete? odie 1 Quote Link to comment Share on other sites More sharing options...
Ben Prater Posted January 20, 2014 Share Posted January 20, 2014 for 4k…has the 5d mark 3 become obsolete? Most digital film shot today is on the Alexa. The Alexa is not shooting 4k, it shoots sub-2k. ML on 5D3 is freaking amazing. Properly upscale your 5D3 to 4k and I promise you -- nobody will ever be able to tell you were shooting HD or 4k. No, the 5D3 is not obsolete. I suspect it'll be an important camera body for budget filmmakers for years to come. Axel 1 Quote Link to comment Share on other sites More sharing options...
Sean Cunningham Posted January 21, 2014 Share Posted January 21, 2014 I think you meant to say the Alexa shoots sub-3K but for all intents and purposes you can round it to consider the Alexa (some models) a 3K camera with its 2880 horizontal resolution when recording ArriRaw and very much a true 2K camera given it down-samples to 2048 when shooting 2K ProRes. Some models only do 1920 when shooting ProRes but even this is, essentially, a "2K" resolution based on KODAK's own precedent. If you were to scan a non-silent 35mm negative at "2K" you ultimately have 1828 pixels across for picture information. Lots of films have been posted this way either because the filmmaker/DP wasn't interested in jumping on the Super-35 bandwagon or because they didn't want to shoot some portions of their film with one standard and the rest of the film with a different standard. That post was still considered "2K" even though you don't have a full 2048 across of actual picture information. I say "was" because I don't know that it's that common anymore, given the proliferation of Super-35mm. But, yeah, you can scale good looking 2K up to 4K and none would be the wiser, especially starting with RAW footage. Quote Link to comment Share on other sites More sharing options...
