General Help Q&A / Re: RAW fps override time lapse

I know, I use triple stages Peltier to cool low flux cameras ;)
(Delta T ~40°C below the ambient temp is usual for me)

But the stability is also important.
With the thermal bridge body/CMOS there's no way...

I don't think my 550D last too much, I can crack it open after warranty expires. then I'll try to hook up some copper inside.

Has anyone heard of any progress on the Mosaic Engineering VAF filter for the 50D?

this should fit to 50D, since they have the same size of hole in front of the lens. http://www.mosaicengineering.com/products/vaf/txi/main.html

Probably they are changing the encryption used on the firmware. Let them keep their under performing 1DC.

its about time, they're changing it in every 3 years or so.

on the movie tab you can adjust fps override option, from 0.2 (on eos m min 0.455 to 35 possible) to 65 frames, there is a video in the forum, he used 48fps 1080p RAW on 5D Mark III, looks nice. if you'd like to shoot a timelapse or sth else you must click to advanced tab to adjust shutter speeds for your needs, I'm using mostly 25fps with 1/40 to 1/1600 option for RAW video and 1fps for timelapse 1/1 to 1/15 with ND filter

Insulting other users isn't helping your cause.

Also, if you feel that a developer has not fully understood your proposition, you should probably,

A)  Take note of the other features that have been described to ensure that they do not fulfill your current requirements. 
B)  Explain to the developer calmly, and in a manner that shows respect to the knowledge they have over the code they look at for hours/day, how exactly their suggestion does not fulfill your requirements so that they might have a better idea on how to accomplish your goal.

Please watch your tone in the future.

just did to you. use the information. I probably see the results in 12 months released by a1ex.

DPI only affects print detail.  It has no affect on video.  Video displays have a fixed number of DPI that is tied directly to resolution.

tell me something I don't know. they are marketing guru's.

Looks good from the video, I just got CC at work so I will test it out once I get it installed. Thanks.

I just did, CC hasn't got that module yet.

had a led panel with me but the battery died after a few mins, time for a replacement.

sucks isn't it. I'll go with pack of li-ion 18650s to shot. little things with lot of juice but seriously dangerous when you accidentally shortcut them

ML community is falling apart :(
nah, just ignore those comments, btw can you do 120 fps and hack the 1dx? or do i have to make a kickstarter campaign?

I'm not talking about impossible stuff - language -

seriously, why are people getting snappish if they want things and they got told that there is another way?
this is not making any fun.

there was *no* offense, *no* pun or anything like sarcasm, just a hint what will already cover the expectations and the response is:
  "have you read my post?"
  "go use your little toy!"
  "delete thread and I'll start a kickstarter campaign!"

damn, this is not what the magic lantern community is built on.

Interesting ...

So, I assume that using an intermediate codec is not beneficial in regards to h.264 , correct?

thanks for your post

np, you just increase sharpness or decrease chroma noise but not the bit depth.

This is what I'm referring to ...>

Here is a post I just found on Vimeo's ML group.  The post title is a bit deceiving, but read further down, it gets into upsampling, and some interesting post by Mark Randall, Yellow and Tom Majerski.


http://vimeo.com/groups/magiclantern/forum/topic:253056

I strongly suggest you to read "yellow"s post again, just the 1st paragraph. this video describes it better

if 4.2.0 to 4.4.4 were possible, arri workers had to shut down the facility. from what I know and experienced, its impossible to recover information lost with compression, you can always interpolate it but no luck, here is the thread for upsampling http://www.magiclantern.fm/forum/index.php?topic=8116.0

It helps. When a 400f/2.8L is on the camera (or this inverse, question of weight ^.^) this lens _massive_ is 'cooling' the camera through the magnesium body. I ever noticed ~5°C less on the CMOS.
But it's not enough to be efficient: The cooling device has to be directly back on the CMOS, the thermal bridge between CMOS and body is to small.

peltier can freeze cmos to death if you know what it is :))

you will still have to deflicker the output, no matter how precisely you compute expo parameters
ettr exposes optimally (want math proof?)
you can do any kind of ramping in post
so why bother?

ok, nevermind, delete thread and I'll start a kickstarter campaign!

isn't turning intervalometer and silent pics on at the same time a good idea?

of course it is, you keep your shutter count but resolution is much much lower than normal.

You seem to be suggesting that knowing the approximate sunrise/sunset time would help the camera decide what to do? Determining the correct exposure is impossible from that - you'd still need to allow for current sky conditions, moon phase and location, streetlights/light pollution, altitude (since it affects sunrise/sunset times), shadows from landscapes or buildings, latitude, camera direction (into/away from sun), ...

If you simply want to know when sunrise or sunset is on a given day so you know when to go out shooting, you'd be MUCH better off with a mobile app like Sun Surveyor to help you plan ahead for the sun and moon conditions. Those apps are far more flexible and powerful than anything that could be built into the camera.

Having said that, I can see a little bit of merit in being able to lookup sunrise/sunset times on camera. I just don't see what it would have to do with the timelapse functionality.

well, I think I'm having hard time explaining myself. go use your little toy!

@dmilligan, yep, I've read the other post about refocussing for stars, its cool and definitely worth to try, so bad winter is coming but we still have time for that

Indeed, the only way to get constant and low noise with long duration frames is to use a temperature stabilised cooling device, like we use in astronomy cameras.
And more the CMOS is big (24x36, etc.), more the temperature inertia is big.

Beside, you can find companies who propose modified camera with this kind of device. But it's not cheap...

maybe we can connect peltier's cold side directly to the magnesium alloy bodies?

I don't have one with completely magnesium alloy, but its worth to shot I think.

i bet he did.

the question is, why do you want helpers for problems that you wont have when you used what he suggested?

and I bet I've used his suggestions but my idea is totally different than what he put in magic lantern!

The 1100D is undergoing work to support raw if possible. The builds will resume shortly

magic lantern complier / VM gone too, where can I download it?

have you read my post?

well,

most of us likes to shoot timelapses and our biggest problem is "flicker" on those. so, is it possible to put a calculator, script or a module in the unified to shoot timelapses without spending 10-15 minutes before shooting?

for example, a script can read from camera clock and location set to it then creates a projection for shooting timelapse, from 1/500 to 1/4 at iso 100, f/8 etc.

also, If I can help with it I'd like to build a database of 10 degree GPS coordinate* for sunset, sunrise times from this site http://www.esrl.noaa.gov/gmd/grad/solcalc/sunrise.html

*in the future 6D can shoot everything automatically, we don't have to input anything at all, just power on and run the module.

so, what do you think?
