Favorite Drone Movements for Cinematic Footage
Roberto Pirodda replied to Noah Zastrow's topic in Camera Operating & Gear
Hi all i think that with tele lens you can be very close to aerial takes from an helicopter with gyrostabilized system Notice the difference between wide and tele shot here: https://youtu.be/JZ-ljVAlqFc -

Fantastic work Uli Meyer ! When woman runs it seems higher framerate than 36fps though

Thank you Phil ! -
Hi all can you suggest me a portable HDMI recorder ? I want to record the HDMI uncompressed 4k signal output from a GOPRO hero 5 camera. Thanks in advance. Roberto

Unless you have shot the b/w and color stocks with the same lens with the same focus and f/stop, i think these are prism spots. Do not use f.22, but use a neutral grey filter or better set fast shutter speed if possible. You should set iris at about f5.6 for best definition. It is not so difficult to flip and clean the prism after all.

Angenieux 10mm no focusing ring
Roberto Pirodda replied to Marco Leoncino's topic in Lenses & Lens Accessories
I used that lens years back. To fix perfectly focus you have to screw very well the lens in camera first. Then if you look in the base of the lens ( close to mount) you will find 3 little screws. Unloct them and rotate the lens till you will find perfect focus for your need. Then refix those little screws. That is all -
Hello Margaux, i have some Bolexes, and can sell one of them. It is an EBM model. It is an heavy customized camera. The frame is enlarged from side to side, so in post you can choose wich film format to screen. Example, standard 16 or Super 16 or Ultra 16. I do not know which price to ask, since it is a total different camera from original now, so you can make an offer. I will send pictures on request. This link you can see a video i shot years ago with this camera ( S16 format) . Best regards. Roberto

Looks great ! Is there some vignette on the right side ? I imagine how good it can be on S16. Would not be a bad idea next time to show some girl model instead :-)

Good day Guy, i have a frame by frame scanner for 9,5mm too.It is 2560x2048 pixel uncompressed TIFF output in a folder image sequence. From this image sequence you can convert in whatever video format of your choice. I charge 1 Euro/meter.Are your 2000 feet( 609 meters) loaded in a single big reel ? My scanner can load 120 meters max, but i have not problem to customize for bigger reel. Roberto https://www.facebook.com/265618923958142/videos/268955433624491/

Super 8 wetgate Transfer to HD. Who does this?
Roberto Pirodda replied to Elliott Landy's topic in Super-8
Well, i do a sort of wet gate with diffuse light too. To me diffuse light helps with my sysyem since i have tested collimated light with worse achievement . I soak the film with vaseline oil then pass trough mechanical cleaning system. This way dust and dirt are removed and the film remains wet. Finally i scan the film emulsion for the highest quality. I can scan from sd to 2.5k to image sequence. This system works best with reversal, with negative film the difference is not noticeable aside dust and dirt removed. Here a brief description. (hem , the voice is robot,sorry for some weird pronunciation) https://www.facebook.com/265618923958142/videos/268955433624491/ -
Bolex EBM - Focal Flange issues with new MFT c-mount lenses?
Roberto Pirodda replied to Matthew B Clark's topic in 16mm
I have used Peleng 8mm lens on a Bolex reflex and it delivers very good images for its price , but you can use only f 5,6 iris. More open or closed iris will degrade quality very quickly -
Bolex EBM on/off switch modification
Roberto Pirodda replied to Arthur Sanchez's topic in Cine Marketplace
well, there is electronic inside EBM ofcourse , but you must only connect + and - connectors ( 12 volts) -
cheap camera + excellent glass = same result as.....
Roberto Pirodda replied to Stephen Perera's topic in General Discussion
Well , a good serviced cinecamera can deliver supersteady frames. My Bolex EMB has nothing to envy those pin registered cameras. An electronic video image, with its artificial/flat look can only forget the warm/pastel look of cine film. To me the "brutal " truth about success of video over film is only related to its immediate availability -
Bolex EBM on/off switch modification
Roberto Pirodda replied to Arthur Sanchez's topic in Cine Marketplace
Well, i have done it and never got problems . After all the switch in the handle acts like a remote ( very short in this case) switch along the cable as you want to do. All the best. Roberto -
Solar Eclipse Film
Roberto Pirodda replied to Stephen Baldassarre's topic in Camera Operating & Gear
Well, i was meaning to practice with sun only, to test exposure. Remember that the less glasses you put in front of the lens the better. I upload a test i made just now with a 1/2.3 inch video camera and 200 mm tele lens (iris at f11) with 2 polarizers . The picture is slighty out of focus because these polarizers distort image quality, i can figure how much bad can be with multiple ND filters ! -
Solar Eclipse Film
Roberto Pirodda replied to Stephen Baldassarre's topic in Camera Operating & Gear
May be i read your post too late and your solar eclipse is already gone. Well, whatever camera you will use , video or film, since it is a total backlight you will get always heavy contrast picture, only white disk (sun) and only black (moon) disk. Anyway, i would go in this way: use a double polarizer filter and rotate one of these till you can easily see the sun with your eye (BE VERY C-A-R-E-F-U-L !). Then use a telephoto lens that can fill the frame with sun disk. Adjust exposure either by slighty rotating one of the polarizers and or setting iris . You can test it with a videocamera before to shot film. Hope it helps -

Here the Super 8 SMPTE frame taken with 4K session 5. Well, to me quality is not so good, it suffers from the crazy ( exaggerated) H264 compression, not suitable for telecine/datacine purpose. The lens used comes from a microfilm scanner and it is an ultra-high resolving power lens

If you want to use a gopro you have to remove original lens first, and fit a very high resolution macro lens. To open a hero 3-4 cameras is not so difficult, you can find many samples on the net. Other thing is to open a session camera, since it is all glued and sealed one. the only way to remove original lens on a session is to mill the contour in front of the lens first to enlarge the front panel and free the objective then remove with a needle the glue around the lens. Finally, with a specific tool that clamp around the outer objective diameter, unscrew gently the lens. I have just done it, and now i am building a C mount adapter that fits in this camera. As soon as i will upload some stills from S8 and 16 frames

Hello Tyler thanks for reply, well, the only gears that risk damage ( to me) is the pulldown claw mechanism. The others gears could run indefinitely at faster speed than 100 fps, untill they are correctly lubricated. Anyway, i was curious to know if anyone has tried it before with an external motor for example.
-
Hi all, the motor of my EBM is gone, so i was thinking to replace it with a faster new one to achieve higher speed than 50 fps of the original one. The question is : how higher speed can run a Bolex without damage mechanics ? For my purpose 100 fps is the goal. Thanks in advance
