  1. That photo... Like handholding a rhino baby :D I absolutely love these kind of projects, please make some photos of the insides if possible. I was looking at ground glasses on ebay for the purpose of testing lens' projected image circle sizes. I have used wax paper for this purpose, it is not that clear but the image can be easily seen and measured. Sensor sizes can be drawn on.
  2. You don't need much power to cut, edit, color footage. You need a lot of power to render/encode your video. One solution would be to make an edit on your tablet and do the final encoding at home on a PC. I searched for android NLE apps, but all I could find was some automatic editors (why?) and some vfx apps. Android 4.0 had a video editor app, so it is possible. It could do basic cutting, trimming.
  3. Thank you, well the project is on pause. I am currently transitioning to Micro 4/3, I bought a GF1 and I am testing the lenses on it.
  4. Warp works for me this way (letterbox 1080p anamorphic): Create 1920x1080 sequence Add 1920x1080 anamorphic footage Add Warp stabilizer Desqueeze (reduce height)
  5. As far as I know these EdMika mounts are reversible conversions. You don't ruin your lens, you can always install the original back part of the lens, the FD mount. There are tutorial videos on youtube about it. You just have to unscrew 3-4 screws, remove the FD mount, install the EF mount, reinsert the screws.
  6. I hope many BMPCCs will pop up on ebay. Cheap, useless, obsolete BMPCCs.
  7. 1. $0 - I have my beautiful Helios lenses. 2. $300 Don't take these as an insult, that is just my budget. Are you thinking of a 49 or 52mm filter thread and adjustable alignment? What size are you planning for the adapter? Sizes like a Century anamorphic?
  8. He probably meant that bigger sensor = more shallow DoF which brings out the anamorphic characteristics, look
  9. I would want good 1080p first, like blackmagic prores 1080p and such for very low price. I think most of the first 4K consumer cameras will have some bullshit codec with low color depth, low bitrate and sharpening pushed to the max.
  10. Yes but that is not video mode, that is burst picture mode.
  11. Noone will release a firmware that allows only 10 seconds of 4K I think. I know about the V1 but it can only do that in raw image mode, no compression, no audio. You need to process and compress raw data for consumer 4K video. Even the better amateur filmmakers and even professionals suffer with raw workflow so that is clearly not an option for consumer 4K which we are talking about. The device needs to be built with component intended for 4K.
  12. 4K is four times as much data. Most dslrs do 1920x1080 by not reading out the whole sensor, but only 1920 colums and 1080 rows and skip the other lines in between so they use less pixels, less data (this causes moiré and aliasing). For 4K it would need to read out 2 times as much colums and 2 times as much rows of pixels. This is a lot of work. It would also need much much higher bitrate compression to achieve the same quality.
  13. You are not exactly right. The fact that the sensor has enough pixels does not mean it can output full resolution images at video speeds (24, 25, 30 frames per second). It all has to do with sensor output, processing power (compressing the video), buffer and output writing speeds. The camera has to read out a hell of a lot pixels from the sensor at least 24 times per second, process it and compress it so you can store it properly on the camera's SD. Check out the still camera, how many FPS do you get from burst mode? 3? 5? 10? That is still not 24. Overheat is one issue, but not the main issue here. You can always use fans, like some pro cameras do.
  14. I too have a 550D and currently I plan to order a Blackmagic Pocket. It would be hard for you to get that wide angle on such a small sensor (16/3 = 5mm, so you will need a lens that has around 5mm focal length for it to be equal to fullframe 16mm). Today I looked at this page for SD Card info about the BMPCC. Recording time are really low for even the highest SDs so I am planning on using ProRes. If you need really wide for skating then GH series is better I think.
  15. I'm not rounding 1.5666 to 1.57 in the middle of the calculation, that is what I meant. Also I would not use odd numbers as resolution, that is why I got those end numbers but you are right.
  16. I would start calculating from a different point but the end results are the same: target aspect / squeeze x vertical resolution = horizontal resolution 2.35 / 1.5 x 1080 = 1692 (1692x1080) 2.35 / 1.5 x 720 = 1128 (1128x720) 2.39 / 1.5 x 1080 = 1720.8 (1720x1080) 2.39 / 1.5 x 720 = 1147.2 (1148x720) This way you have the least amount of rounding errors.
  17. As far as I know it is Möller actually, can be written Moller without the accent or Moeller for more accurate pronounciation (ö=oe). Same thing.
  18. I don't have a super8 but I think the idea is great, would be better if it was not recording the image projected on a ground glass. Instead it could have a super8 sensor directly gathering light from the camera's lens, sensor in the film plane, not a ground glass. This thing is like the iphone Canon EF adapter, that also has a ground glass and the phone's camera focuses on that.
  19. Ridiculous. Just look at crap chinese camera accessories that can work with anything that has power. There are many camera LED lighting panels that work with old sony camcorder batteries, nokia cellphone batteries, AA or AAA batteries, I would not be shocked if you could stuck a potato in it and would still work. That is how it is supposed to be. I have a Canon 550D and bought 5 separate batteries for $5 each, What the hell does the battery matter. For warranty issues just LOG the battery that was used so the service can read it post mortem and tell you it was all your fault your camera died. That is highly unlikely though. I had a Sanyo camcorder with 3 3rd party batteries and the one that died was the original genuine battery, it had a big hump on it...
