I bought a 2nd hand Oneplus 8 Pro (Android phone from 2020) to try shooting raw video with the motioncam app - the app is pretty stable overall with that phone. Below is a quick video I shot yesterday with it on the Emirates Air Line cable car in London. Worth watching on a large screen and set the video to 5K. The phone has 3 lenses (ultrawide, wide, 3x tele). They all work fine at 4k up to 60fps (limited record time at that frame rate). This video was shot at a resolution of 4000x3000 (full sensor area) at 24fps using the RAW10 mode (which I guess means 10 bit raw?). The data rate is about 12.5gb per minute of footage. I exported it as cDNG uncompressed raw files, and edited it in Davinci Resolve. The individual DNG photos from the video look very nice with lots of details. It's incredible what these phone sensors are capable of without any processing. The rolling shutter is a bit of an issue - but I was on a cable car which was moving around quite a bit. I stabilised the footage in Resolve but that occasionally introduces some wobble in the image. The shutter speed was high on this as I didn't use an ND filter. I later found out you can record video straight to an external Samsung T5 SSD drive, which makes things much quicker since you can completely bypass the phone's internal memory. I made the music in the video on a Sequential Prophet 12 synthesizer.

@projectwoofer Yes prices for those synths have risen - let's see if they continue to do so in future or go down again! Video Enhance AI can be good, though it does make things look a bit plastic - but you can add grain to make it a bit more natural looking. @PannySVHS Thanks so much for checking the Fuji XT4 video! That's actually my brother's video - I share the channel with him. He has the Fuji and a Canon 30D. I have a Panasonic S1H, Canon EOS M and the Sony point and shoot cameras. I'm not used to writing in forums in general - but good to know it might be better to use the main forum for this kind of stuff! @kye they should add these high frame rate modes on larger sensor cameras, but maybe it's too complex to do for reasons we don't know? Or at least they could make an interchangeable lens version of the ZV-1, keeping the same 1" sensor. It's true though that in the smartphone examples linked above the quality looks better than what you get on the RX100 / ZV-1.

Thanks so much for all your comments and for reposting @PannySVHS! The colour that comes straight out of camera on the Sony RX100 VII and ZV-1 cameras is great using standard colour profile. Haven't really tried the s-log formats as couldn't work out how to colour correct. Standard profile has terrible dynamic range but the colours look absolutely fine - good enough for me. 1000 fps on these cameras isn't good though, and it's cumbersome to use. You have to set focus, focal length and exposure in advance, and lock those settings before you can shoot. Then if you want to change the settings, you have to get out of locked down mode. @Owlgreen You have a 1 second record time with the ZV-1 and a 3 second record time on the RX100 VII in quality priority mode at 1000 fps. You can double those times if you select "Shoot Time Priority", but I'm guessing that halves the quality. I haven't tried that mode - the "quality priority mode" is bad enough as it is. After you record, you have to wait a long time for the camera to save the footage. For example if you shoot for 1 second, you then have to wait for 40 seconds for the camera to save the clip (i.e. if shooting at 1000 fps and saving to a playback speed of 25 fps, that's 40x slow-mo). Don't think there are any affordable interchangeable cameras that shoot at such a high speed? It would be nice if mirrorless cameras had such an option, even if cropping into the sensor a lot. @projectwoofer the Roland JD-990 is nice, you're lucky to have one! Was looking into get one but they're quite expensive nowadays. I've recently ended up with a Roland D-550 rack though which sounds very impressive too. Below are two more 1000 fps videos I did, without using the vhs filter this time. I did use however use Topaz Video Enhance AI on these videos... otherwise the quality is awful, especially in lower light. This video was a 3 second or so clip of a plane landing at Stansted airport using the RX100 VII, which turns into 2.5 mins of footage when played at 1000 fps: And this one is combination of normal speed and slow motion, again with the RX100 VII:

I've been making some creative videos for the synth music I compose, mostly recording them with the Sony ZV-1 and Sony RX100 VII at the moment. I've been trying out recording high frame rate 1000 fps on those cameras - it looks awful but it's a nice feature to have! Here's a video I recorded entirely at 1000 fps on the ZV-1 (40x slo mo), since it looked so bad I added a VHS filter on Davinci Resolve to fully embrace the retro style.

ntblowz reacted to a post in a topic: Making a retro style factual program with Panasonic S1H
-
I've started working on a new series of slightly light-hearted youtube videos which parody old British factual / educational TV programmes (i.e. inspired by Tomorrow's World, Look Around You etc...) - complete with a classic continuity announcement after the end credits. I'd been doing synth music demo videos and simple camera tests on this youtube channel for years, but wanted to try something different and hopefully a bit more creative, and also to be able to collaborate with friends. Here's the first video. It's not perfect but was a helpful exercise to see what I can potentially improve on in future. Let me know your thoughts! I used the S1H - shooting in 6K. Shame I added the retro filter as it looks amazing without it, but I thought it went well with the video's style - won't be using it on every video in future though. I'm also using stock footage for b-roll from a website I'm subscribed to, which hopefully fits the style of the video. The text was written by a friend many years ago for a university radio show. Maybe we could have revised it a bit to make it work better for the screen - will keep that in mind in future. My channel's main topic is synths so I've kept that theme in this video, having composed the background music with one specific synth.

Highly contradictory reviews on EOS R6 overheating limitation
Alpicat replied to Andrew Reid's topic in Cameras
Johnnie provides some info about how long he was filming for in his comments: "Looking at my interview timeline, the max i could record was around 9 minutes. Saying that, I guess the camera “gathered heat” while filming some short clips before and when left on “standby” in order to arrange my framing and light." "I did’t get near the 40 minutes benchmark Canon measured. I guess what they did, is taking a camera “out of the box” and let it run up until it overheats. In reality, we work a bit differently. We film short clips. We leave the camera “on” in standby mode for composing the shot and take care of other (Little) issues like lighting and sound. All this is building a certain heat inside the camera body, so it can be that by the time you need to film your main interview, the camera will shut off much earlier than the claimed 40 minutes." -
For the S1H it would be nice to ask if they could add the ability to record open gate 5952x3968 (full sensor area / 3:2 aspect ratio) in Prores Raw up to 24 fps on the Ninja V. The data rate at 24 fps would be less than shooting 5888x3312 30 fps 16:9 Prores Raw on the Ninja V, so it should be feasible? The ability to film with the entire full frame sensor area on this camera is unique and it's my favourite feature - I prefer it to the cropped 16:9 look. It's just a shame that the h.265 codec is awful to edit with (on WIndows at least) It's actually already possible to record regular Prores HQ with the full 3:2 sensor area on the Ninja V, the resolution is limited to approx 3240x2160 though, which is ok - but Prores Raw at full resolution would be better!

It would be amazing if Metabones did a speedbooster to compete with the Kipon ones, but ideally made it 0.64x or 0.58x to make better use of the 645 imaging circle. The current price of the SL to Mamiya 645 version isn't that bad in Amazon UK, compared to the prices on ebay at least (where you have to order from China). Here it is: https://amzn.to/3dOKTUK The test I did with the Kipon on the S1H is in the thread below. I mentioned the speedbooster was a bit soft with the Mamiya 80mm wide open at f1.9, but have since discovered that it's actually the lens that is soft, not the speedbooster:

Yes they have medium format speedboosters options for nearly every full frame mirrorless camera mount - also Canon RF, Leica M and Sony E. They're not always easy to find online though. @zerocool22 the build quality of their speedboosters is completely fine and very solid - there are no moving parts on those. The only thing on the Mamiya 645 version is that the lens locking pin has little resistance and the lens could potentially fall out fairly easily if you're not careful.

I have the Mamiya 645 Kipon focal reducer for the S1H and the 80mm at f1.9 it's a bit soft and the image seems to glow a bit. I think that might possibly be an issue with the speedbooster not being able to handle fast apertures, rather than the lens. I heard someone else who had the same issue with this combination. You can very briefly see this in the video I shot below, at the 1:20 mins mark, when I open up the aperture to max for a second. It's more noticeable in bright conditions than in low light. f2.8 it's fine though - even around f2.4 it's ok. Can't find the Pentax 67 one, but with the Mamiya and Contax ones, linked below, you can add an additional adapter to mount Pentax 67 lenses (and also have the option to use 645 lenses) so it's probably a more versatile option? GFX to Mamiya 645: https://www.ebay.co.uk/itm/Kipon-Adapter-Focal-Reducer-Speedbooster-for-Mamiya-645-Lens-to-Fuji-GFX-Camera-/122599541498 GFX to Contax 645: https://www.ebay.co.uk/itm/Kipon-Adapter-Focal-Reducer-Speedbooster-for-Contax-645-Lens-to-Fuji-GFX-Camera/333350155153 You may get vignetting on some lenses if using this with the GFX due to speedbooster limitations, however I may be wrong. Alternatively Metabones make a speedbooster for the GFX which definitely won't vignette, but it only takes Hasselblad lenses: https://www.metabones.com/products/details/MB_SPHV-FG-BM1

Panasonic S1H review / hands-on - a true 6K full frame cinema camera
Alpicat replied to Andrew Reid's topic in Cameras
Here's a test I did with the S1H using Mamiya 645 medium format lenses on a Kipon Baveyes 0.7x speedbooster. Shot in 6K H.265 using the whole sensor area which works really nicely with the medium format lenses as it maximises their field of view. The resulting equivalent speedboosted frame size is approximately 51mm x 34mm - slightly larger than what you'd get with 70mm film (definitely taller due to the 3:2 aspect ratio). It's still quite a bit smaller than IMAX though - equivalent to around half the surface area. I mostly used a Mamiya 645 Sekor C 80mm f1.9 lens and also a 35mm f3.5. I had an SLR Magic variable ND filter on at all times as it was a very sunny day. This is shot in V-Log and edited in Adobe Premiere which is able to handle the H.265 files pretty well. Would have preferred using Davinci Resolve Studio but it struggles a lot with these files even though I have a fairly good computer (AMD 3950X with an RTX2080 graphics card). I have updated the camera to firmware version 2.0 and set the noise reduction to -1. One of the shots was done at 180fps / 1080p. The IBIS works pretty well, but can get quite jittery - it's difficult to keep the camera stable handheld when pulling focus on the Mamiya lenses as they have quite a long focus throw. I composed the music using a virtual version of the Mellotron instrument. -
He's making a documentary about himself: https://afroditefilms.com/chroniclesofketchrossi he kind of reminds me of Bhagavan Antle from Tiger King - benevolent and almost like a god. He does seem like quite a legend - he said he wants to produce, direct, dp and act in his coronavirus film, as well as cook for cast and crew every day. Not even Tommy Wiseau was capable of taking on quite that many roles on his film. I'm sure he's a very nice person (at least from what I'd read in the past), but I'm just not sure about some of his ideas.

With the amount of subscribers he has, it's possible some companies have provided him with kit to review - at least in the case of Insta360, Kinefiniti and DJI maybe? As for the Arris and Canons, if he's a DOP or there's a DOP he works with who has a good relationship with a rental house - sometimes the rental house is happy to provide a good deal or return a favour if the DOP has brought them a lot of business previously. Who knows if he does something like this. Although he does say he bought an old Alexa so he must have some money

Panasonic S1H review / hands-on - a true 6K full frame cinema camera
Alpicat replied to Andrew Reid's topic in Cameras
I picked up my S1H from the shop in the UK on Tuesday! I had ordered the S1 originally in late August, but the day after I heard that the S1H would be able to output Prores Raw and I changed the order straight away. I only have a set of Mamiya Sekor C 645 lenses and the Kipon Baveyes L-mount medium format speedbooster at the moment. These work really well with the IBIS, the stabilisation definitely isn't perfect at all but the movement feels fairly natural. I decided to shoot an unboxing video, the first time I've tried this! Also shot a little bit of footage but it was already nighttime so couldn't do much (jump to 02:50 for the test footage). That was shot in UHD 10-bit 422 All-I 25 fps, with the Mamiya 80mm f1.9 lens, at ISO 10,000. It's soft at f1.9 but stopping down improves things. Not sure if the speedbooster reduces sharpness too. Not sure I'll have time to shoot more any time soon as this arrived just when I'm very busy, but look forward to shooting more! It's a heavy camera and does get a bit tiring if you need to hold it a long time, but it's not that bad!
