I’ve got a couple of requests to upload the Arduino Code for my Motion Controlled Dolly again. Since I’ve updated my homepage, some of the old Blog links and resources do not work anymore. Therefore I repost the whole thing again:
Here is the final code for my Motion Controlled Dolly (based on Arduino and Easydriver) with super smooth acceleration and deceleration ramp: You can download it here: Arduino Sketch ver.03
(you’ll also need to download the „Accel-Stepper library“ v1.5 from Mike McCauley) A big thank you goes to the programmer Brian Schmalz from www.schmalzhaus.com
The motor I’ve used is a hybrid stepper motor from Trinamic that is optimized for micro stepping. The code works out of the box with this motor: QSH4218-51-049 (I’ve got it from www.reichelt.de
for EUR 29,- ) If you use a different motor you might have to ... Read More...
The new version of DaVinci Resolve 10 is finally out there and it works now very good with the „Magic Lantern RAW“ footage from a Canon 5D Mark III. No more fringing or aliasing in the footage! The quality is just amazing!
Some great footage from Andre Meyer can be seen here: Beauty in Nature (5D MK3 RAW)
If you want to learn DaVinci Resolve I can highly recommend the video tutorial „DaVinci Resolve 9 Core Training“ by Alexis Hurkman found on rippletraining.com
Just finished building our 2nd editing / color grading suite. The old trusty Pentium 4 was way too old and had to be replaced with something faster. I’m still doing my main work on a 17“ MacBook Pro but I’m toying with the idea of getting a full fledged new iMac (late 2012) in july.
Yay! - The sun is shining again, enough with the rain! Caro is flying.
After searching for days I’ve found a promising adapter (pdf datasheet FB4658 VER:1.1
) that could work with a special SSD that has an IDE/ATA port already integrated. This adapter is sold in germany through the company ES&S Solutions GmbH. I’ve asked them already and Im waiting for a response. The SSD is an OWC Legacy Pro SSD 2.5“ IDE/ATA
and they claim on their page it’s very fast with Read: 285 MB/s / Write: 275MB/s. It is available in sizes from 60GB - 480GB.
In theory this would be fantastic because the CF controller inside the 5D Mark III maxes out at 167 MB/s and this will be sufficient to capture the RAW video data even at higher resolutions than FullHD. I still don’t know if this whole concept will work and also if the adapter pins support UDMA. These CF to IDE adapters are used in embedded PC systems. So if someone has such an adapter please try it out and let me know. Btw. this IDE/ATA SSD needs of course external power.
Just exploring new ideas and developing concepts on how to alternatively capture 5D Mark III RAW Video to SSD. This concept is very broad and applies to all cameras on the market because they work more or less in the same way. Faster and bigger CF cards are coming out soon but the CF controller inside the 5D Mark III is still limited to max. 167 MB/s. Until then Im thinking on how to get to the RAW stream inside the camera the easy way (maybe without opening it at all). I still don’t know if the HDMI LSI is directly behind the MPEG CODEC IC.
It might be a long shot but maybe there is a way to redirect the RAW data to the HDMI OUT port on the camera. I can imagine that Canon faced the same problem redirecting the uncompressed 4:2:2 signal to HDMI with their new firmware 1.2.1.
Canon EOS 5D Mark III can record super high quality 14bit RAW video! This is so AMAZING! I can’t believe it. I knew it all the time that Canon, Sony, Panasonic and other companies are playing games on us by crippling their products intentionally to gain more profit.
Now that Magic Lantern team made the impossible possible (Thank you guys! You’re amazing!) getting super high quality RAW Video from a Canon 5D Mark III
we need to find a way to store that huge amount of data. It works with 1000x CF cards but there are still dropouts. Trying to store the data directly to an OWC Mercury SSD bypassing the CF card. When faster cards are available this bulky setup will be obsolete anyway. Still not done yet.
--- UPDATE ---
Need more info about the electronics in this camera. Please contact me if you have the Canon 5D Mark III Service Manual
Seems like someone has found a proof of concept that „60fps 4K RAW“ is possible in a 200$ consumer cam.Link to EOSHD BLOGOriginal Vimeo Link
