Only the Rec.2020 Hybrid LOG Gamma picture profile is available in this 10bit mode, there is no standard picture profile. In the stills mode it only shoots 8bit 4K. You have to be in creative movie mode on the dial to access the Rec. The camera uses a broadcast safe RGB range in 10bit of 64-940… A bit like shooting 8bit at 16-235, this prevents the clipping of highlights and shadows by your display, PC or NLE. The file format wrapper is MP4 but no option for MOV. The H.265 4K 10bit files are recorded to the DCIM folder with photos, so there’s no PRIVATE directory folder to navigate as there is on a Sony camera, thankfully. Everything they have told me so far says that the S1 is a video oriented model, but it clearly isn’t to the extent that the GH5 is.Ĭlip sizes are incredibly compact given the quality. I do wonder if Panasonic held back on certain advanced codec options on the S1, to leave room for a S1H or video orientated model later. Unlike the Fuji X-T3 10bit H.265 there is not yet an option to select a constant bitrate mode. The bitrate is listed as 72Mbit in the menus but that’s not a constant bitrate and varies depending on the workload presented to the encoder by the images you’re shooting. The 10bit 4K offered out of the box right now on the S1 is equivalent to 140Mbit H.264 (similar to a Nikon Z6 or D850) but half the file sizes. The Nikon Z6 will get ProRes RAW via HDMI “from May/June onwards” and that’s free, so something for Panasonic to consider there. Initially the Panasonic S1 will use normal H.265 at quite low bitrates, no raw, before a paid firmware update later unlocks higher bitrates in 10bit and V-LOG, but still no raw. Blackmagic of course now have BRAW on the Pocket 4K camera. Sony for example, on the upcoming A7S III is said to be using H.265 compression in their RAW codec which is an interesting hybrid of the two. Rec.2020 colour is used in 10bit mode along with a Hybrid LOG Gamma curve, which make the source files particularly good for grading.īroadly speaking, the Panasonic S1 H.265 codec carries on a trend that began with the Samsung NX1 in 2014 towards replacing H.264, but it’s been such a slow trend that advanced compressed RAW formats are now available that balance smaller file sizes, ease of playback and editing with image quality as well.
So now’s your chance, if you’re wondering how good the initial 10bit codec is at just 72Mbit or how well it grades, to download my files and have a look for yourself… I couldn’t offer any original files from my shoot in Barcelona as the firmware back then was version 0.7. The 4K full frame S1 is on my desk at EOSHD HQ and for the first time it’s the final released camera that is shipping to stores, with firmware version 1.0.
