Frame rate? Resolution? MLV or RAW? ExFAT or FAT32? How much free space remaining after break?

ExFAT? . . . ExFAT is not supported on the 50D. FAT32 only - unless someone has figured out how to do it.

in non-crop mode, i can record 15-20 minutes using a Komputer Bay 64Gb 1000x card, 23.976 fps, Global Draw OFF, MLV Recording, and keeping the 50D in a shaded area. Here's what you also need to know - The most important factor - as far as length of recording - for the 50D is camera temperature. You must try to keep the camera cool. My recommendation is that you shoot in short takes pausing for a short period and turning off LiveView if possible before doing the next take. For example, on interviews, you can treat your questions as takes that way you have a chance to let the camera cool down a bit in between questions. Letting the camera cool a bit is especially important if you are shooting in hot sunny day.

umm . . . so It's my laptop's GPU that cannot handle it? Or is it MLRawViewer that can't handle it in combination with that GPU? It's an Early 2012 15" Macbook pro.

-2.6GHz quad-core Intel Core i7
-8GB of 1600MHz DDR3 memory
-Resolutions: 1440 by 900 (native)
-Intel HD Graphics 4000
-NVIDIA GeForce GT 650M
-1TB SSD

I'm gonna try it on my Mac Pro - it's a more capable system.

I'm getting the same thing on my Mac Pro:

NVIDIA GeForce GTX 660
Type:  GPU
Bus:   PCIe
PCIe Lane Width:  x16
VRAM (Total):   2048 MB

On the other hand, MLVMystic has no problem extracting the DNGs from the MLV file and they look fine in ACR. It must be something with MLRawViewer not being able to handle 4K MLV files. This is what I get - all dark:

I compiled Full-Res Silent Pics from the full-Res branch. It works on my 50D. The only thing thing that did not work is Full Resolution saving as MLV file. When I open it with MLRawViewer it's all dark.

Is this the case for everyone using full resolution silent pics?

-I was also getting:

/bin/sh: rst2html: command not found


-I got it to work by putting "rst2html.py" in "/usr/local/bin/rst2html" directory:

sudo ln -s rst2html.py /usr/local/bin/rst2html

Looks like the the remote and the active canon mounts will be funded . . .

with only 2K let to reach their goal and still 3 days left in the campaign, I believe they might just have enough to make the remote...

Help! Does anyone know if these corrupt frames can be recovered? I shot this footage with the 50D during a hot day and I was pushing the camera to it's limits. Some of the footage looks like the frame below. Is there any way to recover these frames? I've included my log file with the camera settings in case it will help. Here's a link to two original dngs - one good, one bad:

Well, I just put in my two cents worth. It is now at €88,723 . . .

Just select the first DNG and click import, the whole thing will be imported (don't worry about the check box). Or you can just use the "Media Browser", the DNGs should show up as a single clip and you can drag/drop it into your timeline.

Great thanks guys! That works in Premiere and Media Encoder. It does not work in After Effects CC 2014 though- I get an error

https://www.dropbox.com/s/67k7r7mjhfxgn8x/Screen%20Shot%202014-09-10%20at%207.28.46%20PM.png?dl=0

I installed it and works pretty well on my mac pro. Only thing is, for some reason Premiere  Pro CC 2014 won't let me import the dngs as an image sequence - the check box is greyed out. Anyone knows how to fix it?

Anyone knows if full-res silent pics is now part of the nightly build for 50D? I'll be shooting a time-lapse this weekend . . . . Please, please, please . . . .

Is it possible to make an H.264 playback module on the 50D? For certain projects, using 3X bitrate is just much more practical than raw. Not being able to play back is a killer though.

+1

That's a great idea, if it could be done . . . . Play back at 30fps or even 24fps on the 50D would be icing on an already very delicious cake!

OK, the DNG's don't look like that, they have a much finer and more acceptable grain. is it just MLViewer that is displaying it weird?

I just got very good results by exporting dng from mlviewer and importing as camera raw sequence into adobe after effects. I adjusted the white balance and crushed the blacks a little bit then exported lossless avi. Can someone please tell me if SRGB is the correct setting for mlrawviewer for this process? Or should I used rec.709, I couldn't find a clear answer on this.

Yes. MLViewer's window is only for reviewing footage, not for quality output.

Compare ISO 100 1/100 f/4 with ISO 800 1/100 f4, both graded to look the same. Which one is noisier? Post the results.



(of course, you can choose other shutter and aperture values, just keep them the same in both images)

Graded to look the same or graded with the same settings? - You probably meant exposure wise right?

Here is a screengrab to show what I am describing:


This is shot at f2.0 1250 ISO (1600 pulled down to 1250 with ML-3)
shutter speed is 50, FPS is 23.97

Now this is a scene lit only by a 100w table lamp, but at these settings I can get a great exposure with reasonable level of noise on 600D, is there something wrong with my 50D's sensor? Or is this normal? It looks fine with adequate light, but in low light the noise is unbearable....

BTW, does RAW Video benefit from the iso's pulled down?

Am I just not used to seeing this noise because H.265 clips the shadows and applied a picture profile? Or is this an unusual amount of noise? I really don't know what to expect because I have no experience with this sensor... I see small black blotches that come and go and a strange criss-cross pattern of vertical and horizontal banding. It looks like a defective sensor to me..

Is h.265 out?

I am experiencing iso noise that is sooooo bad I'm afaid to shoot anything higher than 320. Can someone tell me is everyone just removing it in post? Or am I the only one who feels this way? I have used the t3i for the last two years, and I'm comfortable shooting all the way up to 1250, but 400 on the 50D looks worse than 1600 on the 600D. (to me) am I spoiled? Should I just treat it like a slow film stock and avoid high iso's or is there post magic that makes the higher iso's acceptable?

For a camera such as the 50D, your lens speed is directly related to the quality of shots in low light. A fast (say 1.7) lens will give you more light. And if the lens is made for m43 (APS-C) sensors,  you'll also improve your images in low light because the sensor will be collecting more light. Both of these features translate into using lower ISO settings. Low ISO = lower noise. Couple that with some fair amount of lighting and you have a decent low-light camera - it's not a 5DMIII. So keep that in mind when using the 50D. 

Note:  You may still get images with color casts, depending on other settings used in MLV.  These can be fixed very easily in post:  http://www.magiclantern.fm/forum/index.php?topic=11664.0

ExFAT? . . . That's a 5D Mark III. Right?

Hi podkan,
    My guess is you haven't enabled the raw_rec module in the modules menu. In the Magic Lantern menus, the modules are one of the menus toward the right. In there enable all the fun stuff; raw_rec, mlv_rec, etc. Then turn your camera on/off, and RAW options will appear in the magic lantern movie menu.
    Don't know about your second question, haven't tried that yet.
    Good luck!

PS, was just rereading your question. Also make sure you're using one of the nightly builds, not the main Magic Lantern Stable 2.3 (that won't have RAW recording), http://builds.magiclantern.fm/#/

Actually, don't enable raw_rec and mlv_rec at the same time - one or the other.

Dual ISO video is the same as on 5D2 (so once I'll get it working there, it will work on 50D too).

Silent pictures are limited by FPS override (not sure what's the lowest limit on 50D, you can try and tell us). But you can average a few frames and get a long exposure (with higher dynamic range - if you average 16 frames you get 2 stops, if you average 64 frames you get 3 stops and so on). I have an old patch that does this averaging directly in the camera, if anyone wants to get his hands dirty:

Wonderful Alex, I'll try it . . . Thanks for the help.

I have another question: Does bulb mode work with silent pictures when using intervelometer? In other words, does a 30 sec buld exposure apply to silent picture?

Maybe menoc is asking for dual ISO video?  Certainly dual ISO photos work fine for me.

Yes. Sorry for the confusion. I meant video. So I guess there's some hope? Alex, let me know if there's anything I can help with . . .

@sync24fps - try deleting the .idx file associated with the clip before converting

In fact, it is best to move the mlv file to a hard disk, then convert from there.

Hey Alex, is there any hope of getting dual ISO on the 50D? The 50D could benefit from this even more so than the 5D3.

Your footage shows it! It is even better than what I expected! 50D + VAF is killer combination. I cannot wait longer for my VAF filter - just ordered it few days ago ;o)

Here is what I got last weekend - shot mostly in full sensor without VAF: https://vimeo.com/91965491
Using Cineform RAW workflow to Adobe Premiere - that is pretty awesome too

Ordered a VAF for my 50D last week! Should be here within a week!
