webrunner5 Posted March 30, 2018 Share Posted March 30, 2018 There is this ungraded RXO footage to play with, I would presume S Log 2, which is on Vimeo from the comments. Not too fond of no auto focus during video recording! . Quote Link to comment Share on other sites More sharing options...

Not too fond of no auto focus during video recording! . I downloaded the "original". It is a 15 Mbps file! Junk. This is not what the camera produces internally (50Mbps XAVC S). I will upload to Vimeo later both 50Mbps internal HD XAVC S Slog2 and 4K Slog2 ProRes video clips, not processed.

markr041 Posted March 30, 2018 Author Share Posted March 30, 2018 Here is the Vimeo upload containing original ungraded, untouched FullHD 60P XAVC S Slog2 clips straight from the camera. I had to delete as their was an error. Stay tuned. In contrast (literally), here is the graded REC709 version of the originally-posted uploaded video shot externally in 4K 10bit 422 in Slog2 so you can see what you get externally: I will upload the original ungraded 4K ProRes clips for the above video early next week.

Then I discovered it was discontinued and was stunned. If you were using the RX0 as an action camera (ie, mounted and used 'blind' - unlike most of the examples here which treat it as a normal camera) then the Ninja Star would be the perfect companion. Maybe Atomos is the Canon of external recorders and protecting the higher models in their range.. Quote Link to comment Share on other sites More sharing options...

But, does this model record 10bit 4K via HDMI? Unfortunately not, just 1080. We need an upgraded model. Quote Link to comment Share on other sites More sharing options...

A new model that did 10bit 4K (and maybe a 'premium' model that does 10bit 4k60) would be excellent. However, it's worth considering that the RX0 isn't as much of a shooting-blind-action-camera as others because of it's 25mm equivalent lens, as compared to the GoPro at around 14-17mm. For the RX0 the rig where it's mounted to the top of the monitor makes more sense. Considering that the RX0 isn't fixed focus, how much of a challenge is it in getting focus? I'd imagine it's got a relatively deep depth of field. Quote Link to comment Share on other sites More sharing options...

This is perfect for blind shooting. You just press one button to go from one to the other and one press back (you can actually use this to do a focus pull while shooting!). kye 1 Quote Link to comment Share on other sites More sharing options...

markr041 Posted March 31, 2018 Author Share Posted March 31, 2018 A graded version of the above Slog2 internally-recorded 1080 60P video. Alistair Chapman Slog2 (+2) LUT, a little saturation and a little sharpening (I think the in-camera Slog2 has none). Quote Link to comment Share on other sites More sharing options...
Don Kotlos Posted April 1, 2018 Share Posted April 1, 2018 I can't say I am convinced with this camera. I am really disappointed by the internal recording quality. They should have downsampled from 4K as in A7s. And unless BM releases a ninja v2 with 4K, recording externally makes it as large as any other camera. The M43 conversion looks interesting but again ~$1400 is too much for this. webrunner5 1 Quote Link to comment Share on other sites More sharing options...

The $249 Z Camera E1 gives you real m43 in a box almost as small, and it does 4K DCI internally. webrunner5 1 Quote Link to comment Share on other sites More sharing options...

cantsin Posted April 3, 2018 Share Posted April 3, 2018 Yep, that's true 10bit footage. Extracted one frame as a 16bit TIFF and counted unique colors (with Imagemagick's "identify -format %k " command) and got 1,024,646 unique colors. After changing the color depth of the TIFF to 8bit, the result was 191,761 unique colors. If the recorder had just recorded an 8bit signal into a 10bit codec, the number of unique colors would have remained the same after the color depth change of the framegrab. - This means that Sony's consumer camera chips are now 10bit capable and that we should expect external 10bit on the next A7s.

cantsin Posted April 3, 2018 Share Posted April 3, 2018 More tests: When I convert the 16bit TIFF to 9bit, 819,542 unique colors remain. When I convert the 16bit TIFF to 10bit, then it's back to 1,024,646 unique colors. That means that the camera's external video signal is true 10bit indeed.

markr041 Posted April 14, 2018 Author Share Posted April 14, 2018 Another first! A 4K HDR time-lapse from the RX0: Recorded in 4K Slog2 using the Shogun Inferno. Converted to HDR HLG in Resolve Studio. The Shogun does the time-lapse using the 4K 10bit 422 from the RX0 HDMI. I can't wait for the Ninja V!
