Wonderful! thankyou for the article. Iv done more testing and with a fully charged battery the camera is shooting at 6.033 fps on M mode. So i guess when the battery is dying like around 32% is when the fps decreases. Does this happen with anyone else? Is it a dud?

sorry i modified my old post but heres what the new one says:

So I did what was described and came up with 4.80 frames a second. Obviously that is slow. Now the question is, is magic lantern the problem or is the camera? and would cannon be able to fix it under warranty?


Iv read up on how magic lantern works and this drop in frame rate doesn't make sense because ML shouldn't be affecting it

After installing magic lantern on my 5D Mark 3 I have noticed a slight decrease in shutter speed FPS rate. If I had to guess probably between four and five frames per second not the standard six frames per second. I took it into the local camera store and compared it with a standard 5D Mark 3 on display and both the camera store supervisor and I concluded that my Mark 3 is shooting slower.

Has anyone else experienced this similar phenomenon? And if so have they been able to fix it?

The store-owners recommended that I sent it into Canon and the cameras only 2 1/2 months old and said that there still is a warranty however, because I installed magic lantern it is probably not covered under warranty anymore so I'm turning to the experts and hope that one of you would be able to help me out with this problem. Thank you so much for your time :-)

I am using the August 22nd build If anyone knows a more stable version and can provide a link please let me know! 

Question about when recording with an external monitor on the 5d mark 3.

1) When you press the record button does the monitor turn off and on and then show the image being recorded on the external monitor? Kind of like a delay.

2) Also, is there a way to turn off the LCD on the 5D Mark 3 and just use the external monitor to prevent the camera from heating up?

Im going to be buying a Lilliput 7-inch LCD monitor with HDMI found here:

http://www.amazon.com/Lilliput-monitor-interface-dedicated-high-definition/dp/B0041I8UAO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1378288510&sr=1-1&keywords=lilliput+monitor

to connect to my 5d mark 3. My hope is that I will be able to shoot raw with the monitor attached with no issues. Please forgive my extreme lack of knowledge on this subject

My first question is,
Has anyone tried this and did it work? if not what were the issues?

Second, when you press record button does the monitor turn off then on and then records?

Third, Is the monitor going to be cropped or is the full screen going to be utilized?

And lastly is there anything I should be aware of when using an external monitor with the 5d mark 3? This will be my first external monitor and I know you guys are the experts

I understand that cannon released a firmware update for HDMI output but unfortunately magic lantern will not work with the new update installed. Thankyou so much for you time and sorry for all the noob questions, long live Magic Lantern!

+1 also. I get frames like the first photo I posted of the building with the black line going down the building. I think it has to do how the data is being written to the card. thoughts?

raw2Cdng is just another converter. It takes the raw files from the card and converts it into Cdng files so you can grade in Davinci Resolve or another program.

Thats not your file messing up. Its the converting process and I had the same problem today.

If your on a PC:

1. use rawanizer to converge all the files together
2. Go to where rawanizer select the converged file (Where you designated them, click the file to make sure you are on the correct one. It should say how many GB's it is and should be over 3.99 GB ** remember to pay attention to the file name)
3. then put the converged raw files into raw2Cdng NOT raw2dng... It might work with raw2dng once converged but i havent tried it I just like raw2Cdng better.

This is the way I fixed this problem
I can send you the programs if you want just message me ur email. Its not your card or files its your conversion process. Hope this helps! Cheers!

So scrambled data like this but worse? :

So theres no picture at all? Can you post a photo so we see what you mean? Is it the entire clip when card is near full or is it just 1 frame? Are you getting an error? For example error corrupt file in slot 13

Have you gotten frames like these:

So I have done more testing with the new and the old card and they both are creating frames with white discolored data on them. I doubt that it is the cards that are bad now because while it is possible that both cards are defective its more likely the camera or when they are being converted (but doubtful because Iv tried 2 different converting programs previously and have had the same problem on the same frames with both). Has the white bands or discolored frames happened to anyone else, is this common and could magic lantern be frying the sensor? I read that all the code does is copy the raw data before its compressed to H.264 and put it onto the CF card so that wouldn't make sense that it is..Sorry for all the questions I just want to contribute and make sure that this doesn't happen to anyone else. Cheers!

Thanks gdicus! Would anyone also happen to know if you can record RAW and HDR at the same time or would that blow up the sensor?

Ok, couple of things:

First of all, your write speeds are ok, but not great, and that could be part of the problem. Hopefully all of these write speed issues will start going away as soon as those new 1200X cards come to market.

Secondly, it sounds like you're shooting in crop mode, I haven't had particularly good results in crop mode. If you're shooting at standard 1920X1080 resolution, you probably shouldn't shoot in crop.

IMHO crop mode isn't particularly stable and I have gotten weird frames myself. I don't use crop mode unless I'm doing very short and very specific shots where I really need that extra magnification.

Thankyou Midphase and everyone involved! you guys are the bomb! It seems that the problem was the card. I have been testing the new Komputerbay 64gb card today and havent been able to produce the same problem yet so everything looks good (*knock on the biggest piece of wood available) I will continue testing tomorrow and will report if there are any problems. On a side note how can you tell if its a good card in terms of speed. I was under the impression that any card that writes over 83mb/s is going to be able to film 1920X1080 is that true? Also, iv been looking at the 1200x cards and JESUS they are expensive!

One thing that I have recently noticed is that every time i turn the camera back on I have to manually change from the SD card to the CF card. Has anyone else had this issue?

Here is the newest 5min benchmark with the new card, Is this a good/fast card?

** one that I have noticed is that at the top of the benchmark test is says "CF SMI Corporation SILICONMOTION SM2236AC" and my previous card (the corrupted one)
only had "CF CF CARD". Why is that? Does that make a difference? Could one be a counterfeit card that Iv been hearing so much about? And again thankyou so much you guys are the best! 

 

What resolution and frame rate are you shooting at?

Do you have Global Draw enabled? What about FPS Override?

Are you getting reasonably fast write speeds on your card?

Do the errors appear when you convert or import in specific apps? Have you tried different conversion/playback methods?

1920 X 1080 @ 24p

I seem to only get the white bands near the beginning of recording IE: 4-6 frames in. The weird frame was 199 frames into the clip.

I was zoomed in 5x or 10x i cant remember when i was shooting one shot and thats where the weird frame came in (I believe). I will test more with 5x zoom to try and replicate the problem again to make sure that is what i was doing. If i get another problem when Im shooting 5x doesn't that mean that the cards not corrupt cause its a consistent problem that is able to be replicated? I mean if the card is corrupt then it would mess up at random times not when I am able to set it and get the same weird frame result sometime, right?

I believe I have a fast enough card (komputerbay 65gb 1000x) Below is a benchmark test-- [it is the aug 22nd build not the 21st sorry!], I ordered another another one to compare and see if possibly the cards corrupt. Now just waiting for it to arrive. [Dont kill me but I cant afford a hoodman steel (._. ) ]

Here is the 5min benchmark test from the first card that may be giving me problems (below)

I convert the raw files with raw2cdng and then open them in Davinci Reslove, I also tried last night with raw2dng and I had the same result with the same frame. So it has to be when its written to the card, right?

Hey guys so I updated the firmware to the august 21st build (THANKYOU Midphase!) and everything is working pretty good however after some more test shots I got the digital line as well as a super weird frame. I was hoping since this frame is different from the previous ones that maybe you would be able to know whats causing this problem and how to fix it. I have noticed that all of the digital lines are near the bottom of the camera and I was wondering if that has anything to do with how data is written to the card? Again thankyou so much for all your help!

here is the first frame that malfunctioned after the update today:


and here is the weird frame:


any help would be appreciated. Is this the wrong place to post these two images on the forum? Should I start a new thread? Thankyou again!

Does anyone have the August 6th build  or a link on where to get it. The august 21st build has a bug when your in the magic lantern live view its gray and shows a bunch of pixels. cheers.

May 18th build? That's two months old. Shouldn't you be using something more recent, like August 6th perhaps (if not the current August 21st one)?

Yes its an old build so forgive me for the noob question Im about to ask: Where can I get the  August 6th build and how would I install it since i already have magic lantern on the camera and cant remove it. Thankyou for your help its seriously appreciated!  I was freaking out that its the camera but it seems like its the card or the build.

Hey guys so i did more testing and the digital line happened again

here is the photo the first time it happened:

and here is the second time:

Does anyone know what is causing this? It only recently started happening. and has anyone experienced a lower frames per second when in photo mode? IE: instead of the manufactured 6 fps its lower? 

also heres an article on if ML voids the cannon warranty: http://www.diyphotography.net/dear-canonnikonpanasonic-can-i-use-custom-firmware-my-camera

Here are the 5 minute benchmark test results for the Komputer Bay cards

Looks like your 64gb card is good [(make sure your doing the benchmark correctly as weoul stated)] also.. you might have trouble with the 128gb card. You need 83MB/s to film at 1080p at 24 frames

Build says v2.3.NEXT.2013Aug22.5D3113, it's lourenco's latest Nightly.

Is that a pretty stable build in your opinion? Would you happen to have a link to it? thankyou in advance! 

Does anyone know how much the frame, or the minute, or hour file size is?? Aprox. of course!! So I can know how many drives to buy!!!

have you shot with 5D raw? Test it first to see if it meets your needs because there are some bugs. How long is your shoot? What are you filming?

* on a 64gb CF card it can store 12 min and 30 seconds of 1080p at 24p -- If its a big project you either need to buy quite a few of the CF cards or buy 2 and do a footage dump on sight while filming with another. Note it takes about 25 min to take the data off of a full 64gb card
10 gb is 2 min
32 gb is 6 min 25 sec
64 gb is 12 min 30 sec
128 gb roughly 24min ** at 128gb some cards have trouble keeping up with the data write

In this music vid: https://vimeo.com/groups/192344/videos/72468916 The artist said that it was 150GB of rushes.

So has anyone experienced the digital blue line during their filming? Any ideas on what could be causing it if its not the card? thanks again! It would really help. Cheers!

This great guy from Youtube named Charlie helped me out. The issue has a lot to do with 32GB SD cards being too large for the firmware. I went out and purchased an 8GB SD card and lo and behold the install worked and the firmware is functioning properly. What a relief. Camera is turning on normally now, everything seems to be fine.

So were you able to remove ML fully? Will we be able to upgrade to a stable version once released? Thankyou for everything, love you guys!

This won't help. Solution is not invented yet. Read this:

http://www.magiclantern.fm/forum/index.php?topic=6035

Thanks Weoul! From the link posted it seems like jkells figured it out so it sounds like its possible. Have you successfully removed ML before? And going back to the digital blue line/ Komputerbay CF cards. Have you ever experienced something similar to the blue lines or vertical lines? Also, heres a video that was filmed on the same day that I got that digital blue line:
https://vimeo.com/73065962

I have done the ML Benchmark CF+SD write benchmark, think it is the write that is the most important and I have test results of 83.4 and 77Mb for the 64Gb and 128Gb KB cards respectively.

Is that too slow?

You suggest the 5min benchmark test, I haven't done that one yet, just the CF+SD write benchmark with the results above.

I would run a 5m benchmark. The results are gonna be saved as a BMP image on the CF card in the root directory. The benchmark results are what the best case scenario for a 1000x card for shooting raw at 1080p. You wanna look at the numbers that have high write speeds figures in megabytes generally write buffer = 16384k.  **Make sure that you are in movie mode because if your in photo mode and have the live view turned off your benchmark could be higher. Once done post a link to the results. Also, you could buy the cannon raw shooters guide by EOSHD which will help you get on track for RAW shooting which is how I learned. You can find that here: http://www.eoshd.com/eoshd-5d-mark-iii-raw-shooters-guide-pdf-book-download

This may also help with the CF card question SteveTownsend: http://www.magiclantern.fm/forum/index.php?topic=5471.0
Hope it helps! Cheers!

Komputerbay cards are not too reliable - just sent back 1 corrupted  card of  4 bought at Amazon. One frame is not a problem, I hope.
BTW how are you going to switch off the bootflag in camera before exchanging it?

I was going to update the firmware back to the original settings on the 5d mark iii, take out the SD and CF card and exchange the camera. I originally had the cannon 6D and realized that it only could record a max of 50mbs so I returned it for the 5d mark iii and I was never contacted about the 6d yet, (*knock on wood) so it seems alright.

So its the card thats the problem? Has anyone else had this problem?

I think I have done everything OK but this si a question whether my KB cards are OK.  Both perform similar and cut out stopping recording at around 1 minute rec time.  The cards I have are 64GB and a 128GB.

Is this OK or are the cards duff?

Have you benchmarked them? [click the trashcan button and scroll over to the Debug menu and then scroll down click benchmark -- then Card R/W benchmark (5min)]

*Tip: Make sure your 5D Mark III's sleep mode is set above 5 min otherwise the camera will shut off during benchmarking

See how fast they can read or write and post the results. Komputerbay cards, it seems,  are all over the place you may get a good one you may get a bad one. I heard that the bigger KomputerBay CF cards (128gb) have trouble handling Raw footage from the 5D mark III at 1920 X 1080 because its max write speed is around 73 MB/s and read speed is around 122 MB/s.

Check out: http://www.eoshd.com/content/10433/which-compact-flash-cards-for-5d-mark-iii-raw-video for more info on CF cards

Hey guys so I have been using the ML 5d mark iii hack for a while and everything is working (minus a few bugs) but today during the conversion process of Raw to Cdng. One of the dng files had a blue digital line across it (for only one frame). I have also noticed vertical lines (most notably around the umbrella) my understanding is that its from a high iso setting however I wasnt shooting high (1600 maybe). I was recording at 1920 X 1080 with a Komputer Bay 64gb card with the 2.3 version May 18th build.

Now Im not an expert which is why i figured you guys would know:

Is having digital blue lines or vertical lines normal/is there a way to prevent this?
Should I exchange the camera? (its only roughly 15 days old)

Again thankyou so much for your time and any help would be greatly appreciated!
