Saw this film last night and I was wondering if anyone knew the make of the camera and lens used. They actually showed quite a lot about the workings of a film crew in the broadcast industry. I'm not quite sure it was realistic, but it seemed believable to me, except for the use of lights in some of the shots. -
Well if that is the case, it’s maybe a little too extreme even for me…but maybe not… My 28-70 will become a 58- (classic focal length!) 145mm (a focal length that has probably never existed, but who cares). Outdoors, no problem. Indoors, hmm… The 18-50 crop lens is going to become more like a 37-104mm which might be better. Or there’s always 6k 30p open gate with just the EIS crop but max 80% slow mo which might work… I’ll have to play… -

This would also explain why Panasonic doesn't offer any 4:2:2 in H.265, only H.264. I think when the Canon R5 came out, many were complaining how uneditable the footage was because it used H.265 and 4:2:2. With the S5ii, I think Panasonic wanted to avoid that. They really seem to be paying attention to professionals. Are you interested in the Frame.IO feature? You can tell a difference if you pixel-peep to 200-600% and A/B the images. I've also noticed a slight color shift too. There are also a few artefacts, but it's still 5.9k downsampled to 1080p 10 bit- not bad. If you slap on a touch of sharpening, no normal view could tell the difference and you have something that would be 5% the size of a 6k image. Thinking of the crop, I think the more interesting EOIS setting is 25fps FF with the 1.43x crop and that 10-18 Sigma. That's the one I'd like to try. -
AFAIK, the GPU in the 'Ice Lake' CPUs has hardware decoding for up to 10-bit 4:2:0 HEVC i.e. 'Main 10' profile, assuming you have a Retina MacBook Air - https://en.wikipedia.org/wiki/MacBook_Air_(Intel-based)#Retina_(2018–2020) Any higher HEVC profile e.g. 10-bit 4:2:2 has to use software decoding on those machines. Not surprised. I often upload stuff to YouTube as 4k 50p using HEVC at 15-30 Mbps (using 'constant quality factor' encoding). I used to use higher bitrates, but decided it wasn't worth the extra storage space/upload time. HEVC is generally a very efficient (quality versus bitrate) compression codec. -
I tend to agree. I associate green/brown with Sony and you’re saying that more magenta (canon?) images can be had in Sony? Simple correction in camera white balance? Or only in post? Maybe a 1/4 black mist? 1/8 may be better? Makes it look less sharp maybe - I fear existential crisis but like c70 colors lol.
