Share Your Videos / 50D and Magic Lantern - Documentary
« on: July 18, 2016, 04:58:14 PM »
Here's a little documentary I did for my artist friend about a group of artists out of Fort Lauderdale, Florida. The Doc was shot with a Canon 50D in RAW mode. Audio was done with a shotgun mic. Syncing was done with a slate and synced manually in post.

Right now, it seems to me that ML is putting all it's efforts in developing for Apertus. You can sort of tell because of little news coming from ML in the longest I can remember . . . or they could be holding out for maximum shock and awe...

This is going to be like the 7D. It was a loooong time before it got ML.

i heard some rumour that you can override the frame rate on the 50d to at least 35fps and some have said 40fps. can 50d users confirm any of this please.

This is misleading. The software will show more than 30fps but "ACTUAL" fps will remain at 30. 50D just isn't fast enough to go past 30 as far as I know. Perhaps there may be a way to do it at a lower resolution such as 480p or lower. The problem is that canon hardware dictates how fast the sensor can be read. Perhaps an idea would be to implement a crop mode hack that would essentially bring the sensor read area down to 1/2.3" or Four Thirds size. The less area the camera has to read from the sensor, the faster it could capture a frame. To do that you'd have re-write new firmware and that won't happen - from ML. (...unless you write new firmware with linux :-))

:).  this is going around in circles.  I have no idea what you are referring to.  Anyway...nevermind... I removed ML

Patience is a virtue. Simply.... Once ML is installed, press the Trash can button to bring up the magic lantern Menu. To access the Video Modes, you must first start Live View, then load the "mlvrec.mo" module from the modules menu, then re-start the camera. Once the camera is back on, start Live View once again and you should have ML Raw ready to shoot. Set FPS overwrite first in the video menu.

...or Just follow this:

I just saw videos from this guy. he claims he is using non crop mode. why is his image so clean?




Yes. It does not look that clean to me either. But there is a way to clean up non-crop mode - use Mosaic Engineering's VAF filter for the 50D. I have one. That's the one I use to clean up the image in non-cop mode.

i understand crop mode gives a clean image. how long can you record 1080p raw on a 1000x card? will a faster card help?

A faster card will help stabilize recording but you will also have to take into account that more CPU heat will be generated by recording at a higher resolution. Crop mode does a full read out of the area being cropped which gives you more detail and cleaner images but it also requires more processing power. The CPU will be working harder so it will generate more heat. The only way to know how long you can record in crop mode at 1920x1080 - using a faster card - is to actually run tests to see how long you can go before CPU temperature stops the recordings.

I'm using the 50D for RAW filming for some months now, and it is really great!
(By the way, thanks to all developers who made this possible! It's unbelievable.)

RAW-Video and also MLV-Rec are working really great.
But sometimes I would like to use the usual movie mode with MOV video files, and not RAW-Video, for filming events etc.
When I record MOV files I set the FPS to 23,976. But when I playback the video files on my PC, it plays back very fast, looks like it plays back in double speed or something.

Everybody ever has the same problem, or know how to fix this?
Thanks!


That's because your MOV file is most likely playing back at 30fps, not 23.976. If you're using quicktime, quicktime will play back the file at 30fps if it cannot read metadata from the file. To playback your files at the correct speed, you may have to conform the video file using something like apple's old cinema tools utility. Or you can also put the file in an NLE's project with the proper playback speed set in the project's properties.

good work bro, what is your work flow was this done with the crop mode, share some more info, the audio ide of things I have covered, jus curious about different wrok flows

Thanks.

Most of the interviews were shot with ML RAW (Non-crop mode) and most other scenes were shot with MLV RAW. The RAW files were exported with the now defunct RAWMagic and most of the MLVs were exported to DNGs with MLVMystic. I processed the RAW DNGs with Adobe Camera RAW. The debayer in ACR did a good job of removing most of the color noise. In later shots I improved the aliasing by using Mosaic Engineering's Moire / Aliasing Filter for the 50D. There is a mix of scenes with and without the filter throughout the film. For example, the scene at 7:40 was shot without the VAF filter and the scenes of the credits starting at 14:19 were shot with the VAF Filter. The VAF filter does a pretty good job of cleaning out the image and fixing the aliasing especially around sharp edges. Some shots were filmed in crop mode such as the one at 00:40 and 00:24. The quality of crop mode was much better but it limited my lens' range so I couldn't use it for most shots. So here's my step by step workflow:

1. Camera's PictureStyle was set to Neutral and the option for "Absolute zero sharpness" was turned on in ML.
2. Scenes were shot in RAW or MLV Raw.
3. RAW files were exported to DNGs with RAWMagic or MLVMystic.
4. DNGs were brought in to After Effects as DNG sequences. In AE Moire and aliasing was corrected and interview audio was imported and synched.
5. From After Effects, DNG sequences with synched audio were sent to Adobe Media Encoder.
6. In AME I exported to Apple ProRes 4444 (I selected the options to rendered at Maximum depth 32-bit, and use maximum render quality).
7. ProRes files were imported into a Premiere Pro project. Further color, slo-mo, and audio corrections were done in Adobe Premiere with round trips to SpeedGrade, After effects and Adobe Audition.
8. Finalized Premiere project was sent to Media Encoder for final file export to upload to vimeo.
9. Media Encoder setting for Vimeo MP4 upload file:

Format: h.264
Size: 1920x1080
Profile: High
Level: 4.2
*Render at Maximum bit depth
*Variable Bit Rate, 2-pass
Target Bit Rate (Mbps): 35
Maximum Bit Rate (Mbps): 35
*Use Maximum render Quality
*Use Frame Blending

Audio:  AAC, 320kbps, 48khz, Stereo

external as in the battery pack or a plugged in power supply?

Either one. But that will not help that much. The best way to manage the 50D is to understand that there is a time and temperature limit to recording RAW whichever comes first - If you're shooting in a hot day, your max temp will be reached quickly and the camera will shut down or lock. If the room temperature is cool, then the maximum temperature will be reached during recording. The bottom line is, with the 50D you have to plan your shots with it's limitations in mind. For example I shot the documentary below in it's entirety with the 50D. All shots lasted 2 minutes or less with a bit of a break in between to let the camera cool off. During the scenes in the roof I kept the camera in the shade when idle and of course, audio was recorded externally.

I got my 7DII last week and had a chance to take take it for a spin over the weekend. It's a superb camera for stills - from the autofocus to the frame rates, to the 16000 native ISO! It's a great Camera! I slapped the Sigma 18-35 F1.8 Art on it and the images are beautiful.

The video capability though was disappointing. It is as bad as the h.264 video on the 5DMIII. But we all know that what Canon gives us is not what is really under the hood and I am willing to bet that Magic Lantern RAW on this camera will be as good as - if not better than - the 5DMIII. The 7DMII in my view is to the 5DMIII what the 50D was to the 5DMII - just a smaller version of the same camera. Video will truly shine on this camera once ML is running on it. Focus tracking especially is going to be really useful for RAW video.

For now I will continue to use the 50D as my RAW workhorse but I think ML RAW on the 7DMII will be a leap!

Raw Video / Re: [ALREADY DONE] Seamless RAW/MLV recording +30 minutes
« on: March 07, 2015, 08:58:18 AM »
Astrophotographers mod their cameras with cooling all the time. There are plenty of solutions out there for that.

I had an idea last summer for a shoot (I live in South Florida) to cool my 50D by insulating it with a rain protector then encasing the bottom in dry ice. A little extreme but never actually tried it. Although, I think it would have done the trick to keep the camera cool. . . or it would have petrified the camera solid. :P

And the question is?

 . . . larger files than 4GB on FAT32? . . .Is eXFAT enabled on the 50D? Heat is a big issue with 50D. I have not been able to do 30 min continuous in RAW.

Does anyone has the .fir and silent.mo with full-res-silent-pics compiled to the 50D?

Have been trying to compile it but can't get it working.




This is from the Jan 29th full-res branch.

@ devs: can you please tell me whats the fastest shutter speed with silent pic right now (with canon 5d mk3 1.1.3) and would it be possible to update the silent.mo from time to time in the #1 post with all the newest additions for the different cams, especially canon 5d mk3 FW 1.1.3 :)))
or for simplification: would it make sense to add the new full res silent pic module to the nightlys.


thanx very much :))


I believe A1ex is working on getting silent.mo in the nightlys. Posting the silent.mo alone may not be a good idea as some dependencies may also have to be compiled. It is best to compile the ML core along with the modules to avoid crashes. I'd suggest you setup a machine to compile and compile the full-res branch.

« on: December 30, 2014, 06:58:24 PM »
No expert here , but due to users wanting 4K on their DSLR's it may be that the new 5D Mark IV have this feature.
If porting ML to it was possible is there a way to Reverse-Engineer the feature?

The real problem is the Hardware. You need faster hardware to do 4K. Trying to implement 4K with hardware that was not designed for it will cause many problems - such as heating (which has many side effects on a clean image). My guess is that the the 5D Mark IV will have a faster processor and will use CFast - a faster storage solution.  There's not much you could do unless you hack the camera, install a faster hardware and make it work with the firmware. That would be a big no, no! (you will be voiding your warranty and not to mention that you'd also be on the wrong side of the law!)

We can't go past the hardware limit. You have to program for the hardware and not the other way around.

i'm considering buying the 50d to shoot wedding videos. do you think using the settings above to get 15 min per 64gb card is reliable?
can you clarify what resolution i will get when you said non crop mode?
also, does this mean the 50mm lens will behave the same as on a standard aps-c non ML hack canon camera?

also confused about resolution. this camera cannot shoot 1920 x 817  ? if not what is crop mode and how does it affect things. does it crop the view of every lens used ?

thanks

A few things in addition to simulacro.

If you're going to shoot weddings, you probably want some fair amount of shooting time. I'd recommend you shoot in non-crop mode. Non-crop mode has a drawback though - you will get Moiré and Aliasing when shooting wide angle and scenes with very fine details. To get rid of Moiré and Aliasing you might want to consider getting the Mosaic Engineering's Optical Anti Aliasing filter.
