I think it is a thing which can be done. I'd like to try and hack one but I don't have a gimbal as I don't have use for them. If you get one open, I'll be interested to see what ICs are inside and see if we can override one
-
Have you tried using linux ? Ubuntu should be able to access the card in read-only at least.
-
Looks more like compression artifacts to me. Where you recording internally or externally ? It wouldn't surprise me if this happened using the internal recording as the bitrate is not that high.
-
The problem doesn't come from sensor size actually but more from pixel size. So you could make a great low light m4/3 sensor. But only at smaller native resolutions
-
There is also the bitrate problem, let say you record in FullHD, AVCHD (24 Mbps). Using a 2x strech scope, you would end up cropping the sides to get a 2.4 aspect ratio which implies cropping 1/3 (approximately) of the image you get. Decreasing the overall bitrate in use. You then end up with a 16 Mbps 2.35:1 image to work in post, which doesn't really allow a proper grade. That is the reason why I don't use the anamorphic on my main camera (AF100). I may very well be wrong, but I'd like to be proven otherwise. Any thoughts on that ?

I'd say both, it's great to have more vertical resolution, but having to crop less is more "storage efficient" to me. (with magic lantern being limited by the card write speeds, it's easier to achieve more vertical resolution in 3:2 or 4:3 than in 16:9 ) I actually shoot more in 3:2 with magic lantern as it allows slight movement in the shot in post if wanted, but 16:9 is just too much cropping to me.

Or you can get a nice set of samyangs (12mm T/2.2, 21mm T/1.5, 50mm T/1.3) So you get a get a nice set of cine lenses

2048*1536 is actually closer to 3K. Would stretch nicely to 4k anamorphic. The bitrate and IQ is not great however from the very few reviews I've seen. I'd like to be wrong on that though
-
What resolution are you using ? According to http://rawcalculator.bitballoon.com/calculator_desktop, you can get continuous recording on the 5d3 at 1776x1184 (3:2) in 14 bit. (1696x1130 3:2 for the 5d2) Are sandisk cards recommended ? I thought only the lexar and komputerbay are able to deal with the bit rate. Anyway, do a write speed test and see the resolution you can achieve according to that
-
Man that is a great great deal you got there
-
Were did you get a BMPCC at that price ? I'll buy one right now !
-
Can we see some pics please ? I'd like to see how much fungus we're talking about.
-
Unless you want to frankestien the hell out of it and rewire the bmpcc's encoder and recording circuitery and magically get the cpu to still communicate with the encoder to control it .... NO
-
10 bit just isn't enough for raw as the data is encoded in linear space and not log space. You would get too much noise (see examples on ML forum). 12 bits looks the same than 14 bits though, so that's great
-
Go MFT and use dead cheap old lenses with a speedbooster :D That is if you like vintage glass.

I bought a 50D just for using it with magic lantern. I get full HD raw for €250 (using anamorphic). If you go with a 5d mk2, you get full HD raw (13+ stops DR with dual ISO) for ~€1000. Yes it is a hack, but you have to love what it gives you for the price. If you don't wanna go with blackmagic in a tight budget, this is the only way to get raw ! But as you said, the 5D mk4 is an expensive camera, and it doesn't offer much. I think the ML team should concentrate on the unfinished projects first (Dual ISO video for 7D/50D & 10-12bit raw for 5d mk2 / 50D). There is still some humph to get from these 5+ y-o cameras I wonder how the apertus project is going, if I remember correctlyctly, some developpers came from ML dev team.

The number of BMPCC and BMMCC that have been sold show that some people are not onto the sensor size race too. Full frame is great, but I prefer S35 or S16 myself, depending on what you shoot, but the clients seem to only care about shallow depth of field :s

Anamorphic for high speed photography (Sankor vs Schneider)
Justin Bacle replied to Hubert Napierała's topic in Cameras
Wah, these pictures are gorgious ! Can you explain the setup a bit ? DO you need macro rings or is the close-up ability only done with the diopters ? -
Anamorphic for high speed photography (Sankor vs Schneider)
Justin Bacle replied to Hubert Napierała's topic in Cameras
The Isco Ultra Star is equivalent to the Cinelux in terms of IQ and close up distance is 1.5 meters too. I don't know a thing about the Sankor Ultra HD though :s -
Sorry, I just began working with it, I don't know eveything about it (yet)
-
If you use Resolve, you may wanna try to convert your F3 Slog footage to ACES and then you can convert to whatever you want. (Not sure there is a specific F3->ACES profile but I can check if you want when I get home)

I have to try that next time I'm playing with my camera. Thanks for the tips
