  1. 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.
  2. 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.
  3. The 8K is 10-bit 4:2:0 (XAVC HS) according to the Sony website
  4. 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."
  5. 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!
  6. 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:
  7. 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.
  8. 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
  9. 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.
  10. 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.
  11. 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
  12. 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!
  13. Hi, the video is from February 2018 so I used the build that was available at that particular time. The video description mentions that I used 12 bit lossless recording, so it would have been one of the experimental builds from the main website (not from the forum) - this was a few months before Danne started doing the SD overclock hack for this camera. Given that the resolution was 1392x1028 I'm guessing I was using 'movie crop mode' which gives you a full realtime view of what's being shot, the preview is zoomed in 3x in relation to the whole sensor in that particular mode (rather than 5x). The Schneider lens was mounted to the camera with a C-mount to EF-M mount adapter. That's good to know! I only ever used the 5D mkII without magic lantern (back in 2011) - didn't realise there was less moire and aliasing than when shooting with the regular video mode.
  14. @Emanuel yes the 5D mkIII is an exception because it uses pixel binning, I meant most of the other Canon dslrs that shoot 1080p with line skipping. From my experience they're worse than the bmpcc.
  15. @webrunner5 thanks! yes this camera now basically has the same capabilities as other Canon dslrs with magic lantern, only it's cheaper and very light. @Emanuel I guess it does look a bit space-age with all that sellotape floating around in front of the camera! @thebrothersthre3 mosaic engineering make these filters for Blackmagic cameras too, it's worth getting one that was specifically designed for the camera you have as then you should get the best results. However I don't think Blackmagic cameras suffer from that much aliasing compared to most Canon cameras?
