  1. 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.

  2. 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."

     

  3. 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!

    I've got quite a few Metabones products and don't disagree necessarily but its difficult to be definitive in this particular case when they don't make a comparable medium format reducer product for any format.

    It would be good if Metabones did provide Baveyes with some competition for these products as the price is pretty steep in Europe at least, though whether this price reflects it being a thus far niche product or Kipon having a monopoly is up for debate.

    I've seen quite a few reviews of the Baveyes MF reducers on Sony A series cameras but not on the SL but I think someone on here has done some stuff with one on an S1 or S1H but I can't remember what thread its in.

     

    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:

    Kipon doing an amazingly wide range of adapters at the moment.

    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.

    Alternative would be the Mamiya focal reducer. That way you could put a 80mm 1.9 on there giving you the eq. of 0.81 x 0.71 x 80mm = 46mm, with 1.1 DOF.

    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.

    I'm still keen to give one a try though. How much are they?

    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

    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

  7. 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.

    Somebody should do a documentary on the guy, Tiger King style.

    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.

  9. 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

  10. 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!

    Do you know what build and settings were used for this first video? I would love to get to that. Thank you so much! First time putting ML on my EOS M and even though I've been a photographer and built my own computers when i was 15...I still find this software a little alien and confusing at the moment.

    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.

    In Magic Lantern RAW (MLV) I had equal sharpness, detail and almost zero moire from both the 5D II with Mosaic AA and 5D III. Without the filter the 5D2 isn't so bad and definitely a lot less moire & aliasing than in the stock Canon video mode.

    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.

  12. @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?

    This place sells them, but they are not giving them away lol.

    I managed to find one of these filters for a Canon 50D on ebay for cheap (I bought the Mosaic Engineering VAF-50D Optical Anti-Aliasing Filter), and got round to making a video with it yesterday in mv1080p rewire mode (full sensor 3x3 line skipping). It works, doesn't get rid of the aliasing 100%, it's still there in extreme situations, but the reduction is substantial.

    I stuck the filter into an EF-M to EF adapter with sellotape, it's impossible to fit it directly in front of the sensor as it's too large - I actually tried to fit it by cutting the filter's frame off, but the glass started cracking straight away so stopped that attempt immediately (you can see a crack in the photo on the top right corner of the fulter, but it doesn't affect the image luckily).

    yeah yeah but, seems there's no way how to properly monitoring... That is, the basics, framing. Have I misunderstood it? Please tell me so...

    That's true and is a big consideration if you're thinking about getting this camera. In general the eos m has never been very usable for video and things haven't really changed that much. If you want a camera that's easy to use - i.e. with proper framing - you'd be better off with a bmpcc or something else. With the eos m you're basically shooting partially blind in some of the modes. 

    I'm sure it's already been mentioned, but in all the raw modes on the eos m you have a choice between shooting with a real time preview that is cropped, sometimes not correctly centred and in some cases stretched vertically by ~ 2x or more extreme in the case of 1x3 mode (the preview looks like uncorrected anamorphic with the bottom half of the frame not displayed)... or you can shoot with correct framing preview but then the display is very pixelated and plays at slow frame rate. It's hard to shoot anything in this mode, unless it's a static shot. I only ever use this mode briefly to check framing before I start shooting.

    The exception to all the above is movie crop mode which we'd spoken about in the previous eosm thread - that mode provides a fully correct preview, but the crop is 4.66x (approx 1/2 inch sensor size) and max res is 1800x1024. Here's an example video using that mode: https://www.eoshd.com/comments/topic/26577-is-the-eos-m-the-digital-super-8-camera/?page=4&tab=comments#comment-227334

    What about 1504x1920? Not continuous without dropped frames?

    With the latest build Danne posted the max resolution that I can set is 1184x2000 (i.e. 3552x2000) in 1x3 mode - I don't know why, maybe beyond that it becomes too unstable and he set that limit, or maybe I'm doing something wrong - but for me it's a nice resolution, it comes out exactly as 16:9 aspect ratio.

  16. It's incredible how much progress has been made on the EOS M in the last few months! I've tried several builds with the 1x3 binning setting but was getting corrupt footage every time, until today - with Danne's latest build I'm finally getting good results in this mode. The max res in 1x3 seems to be 1184x2000 in this build (which stretches out to 3552x2000) - I'm getting continuous shooting in 14-bit lossless. As @Brian Williams mentioned the rolling shutter is really pronounced though, and there's noticeable fixed pattern noise in the shadow areas which I hadn't seen this camera do before. Don't know if these things can be improved in future builds.

  17. 16:9 would be 1736x976 - in the magic lantern menu select 16:9 aspect ratio and that's the resolution that should appear. You'll probably get close to continuous recording without the sd card hack in 12 bit lossless at this resolution.

    I've just seen that the eos m can now shoot 3k (3032x1436) at 24fps in 5x zoom mode. Look forward to trying this later this month when I can. The crop in this mode is  2.76x, or 2x with the speedbooster. Record times will probably only be a few seconds even in 9 or 10 bit lossless raw. 

  18. @henricus If you want to shoot this resolution you have to enable crop mode (I think it's called mv1080p 3x3) - otherwise you're limited to 720p vertical resolution with excessive aliasing. The aspect ratio is what you see in the video,  I guess it's close to 1.5:1 since this mode nearly uses the entire aps-c sensor space. I get continuous recording at this resolution in 14-bit lossless raw if the sd card hack is enabled - i.e. you can record for minutes, until the camera starts getting hot and then it's probably a good idea to stop. Without the card overclock at 10 or 12 bit lossless raw you should still be able to get fairly decent record times from what I remember.

    @Alpicat

    there is some interesting stuff Happening in the magic kantern eos m Thread, if I got. it right they found the 1x3 Mode, which gives 5dmkiii type binning, I don't have the time to get it, maybe you do and come back and Tell us ;) 

    Hi yes I tried it and it works fine. although liveview is a bit crazy with the screen heavily stretched vertically. When corrected in post, the image comes out at an aspect ratio of 4.6:1 which isn't very useable. You can crop the sides off down to 2.35:1 ratio but then you loose quite a bit of resolution. I'll test it further though.

    There's someone who stuck an anti-aliasing filter into their EF to EF-M adapter using sellotape, sounds like an interesting solution! I might try that one day!

  20. At long last I've received the Viltrox speed booster for my EOS M, which means it's now a full frame raw video camera! Seems to work nicely so far, here's my first footage using the whole sensor area. Sorry I keep doing videos of the same thing, hopefully one day I'll do a more interesting video:

     Youtube description:

    First test using the Viltrox Speedbooster with Magic Lantern raw video on my Canon EOS M. Resolution is 1736x1042 (14-bit lossless raw) in 3x3 mv1080p mode, using the full sensor area. The Viltrox speed booster provides 0.71x magnification which makes the EOS M camera practically full frame (1.14x crop compared to 35mm full frame).

    As always, youtube compression makes the footage look mushy compared to what I exported from davinci resolve. The Viltrox seems sharp enough for video, although it doesn't perform so well in the corners for photography, which may bother some people. I used a Tamron adaptall 35-70mm f3.5 for this video. I didn't use the SD US overclock card hack as at this resolution you usually get decent recording times without the hack. Also I forgot to remove the focus pixels on mlvapp. Sorry for the shaky video, this was a very quick test! 

  21. Thanks Andrew for this eye opening article, didn't realise the situation was that bad. Interesting to hear about what you experienced in Berlin.

    It's not passed into law yet. 

    It isn't yet but I've had to start preparing for it (for commercial projects) - had to redo contracts last minute before a shoot to take GDPR and article 13 stuff into account, and had to get everyone to sign again. Have to be extra careful on set now with getting release forms signed from absolutely everyone even if they're hardly visible in the background. If buildings are also considered copyrighted material, that's going to make things even harder!
