Raw Video / Re: Canon 5D Mark III Vertical and Horizonal Lines
« on: December 27, 2020, 09:36:30 AM »
Hello ML Community,

    Thanks so much for your quick feedback. Below are my responses...


    Ok I understand. Thank you for your quick responses. Much appreciated.


     I don't think it's the picture profile honestly because I chose Cinelog-C in Adobe Camera Raw. I first exported a DNG Sequence from MLV App, then chose Cinelog-C. I'll see if I can do more tests. The ISO is 1600, but to my understanding that ISO value is safe to use with the Canon 5D Mark III. Any more details on fixing Cyan? Where is the fix for banding? I tried the most recent 10 bit/ 12 bit Raw build from the ML Experiments Page. Same issue. I can try the nightly builds but recording in 10 bit is really important to me since I can get continuous raw recording, which is important for filming skateboarders. Don't want the recording to stop in the middle of a trick. I think is 4:3 is better (more resolution, wider) with 1080p 30fps, I'll have to test that out, but I don't think it's continuous... More fps is better for capturing skateboarding tricks.


    Yes the problem is the two dots in the red ellipse. What's odd is there is a horizontal banding line where those two dots show up. As well as vertical banding lines. I don't remember seeing the lines before, but I have seen the dots. Bad pixels? Not sure the best way to fix this except for pixel maps which I'm not too familiar with. I have done it in the past. I thought this was an issue with the Canon 5D Mark III I have, but it's happening with both cameras. It's possible if I use the newer high quality 50fps preset that this issue won't be there, but in that mode I won't achieve continuous recording, to my knowledge.

Hello Danne,

    You're absolutely right, sorry for my negligence. It's been a while since I've posted here. The reason I included the video in my room is because I know the issue shows there. But yes, I probably should've shown the issue not in a messy room. Here is a link to a trimmed MLV exported with MLV App:

    It's a bit difficult showing the exact issue, since there are multiple faint horizontal and vertical lines, but in the 4 seconds of the MLV there is a horizontal line you can see.

    In this 300% cropped image, where the white wood is next to the window, there are a few black pixels, and this is where the horizontal line comes across:

     Thank you for the quick response by the way. Thanks for all you do.

Raw Video / Canon 5D Mark III Vertical and Horizonal Lines
« on: December 25, 2020, 09:53:27 PM »
Hello ML Community,

    Below are two clips filmed from two different Canon 5D Mark III's.

    I'm having an issue which involves horizontal and vertical lines showing up in the video. These were shot in 4:3 aspect ratio at 50fps in Magic Lantern Raw Video with 10 Bit Lossless with Alter Bit Depth set to 10 bit. Sound is auto, no mic attached. I used an external monitor, and didn't use fps override. The Build is:

    I've tried not using the external monitor, tried 23.976fps, and different MLV App settings as well as all MLV App settings turned off. I've even tried Batch MLV App. I'm using Cinelog-C in Adobe Camera Raw and SmartImport2 Script with After Effects. Clips are ProRes 4444 XQ. All software is up to date.

    I tried using Neat Video V5 but it made the clips look worse...

    I honestly am boggled as to what is going on. It's possible it's a build issue, but I'm hoping there's something I'm missing that someone can point out. I'm hoping to film some skateboarders soon, so I'm doing all the preparations I can in time for when it's warm out.

    I hope everyone is having a good holiday. Thank you for any input. Please let me know if you need more detail or have any questions. Thanks.

Has anyone found a way of displaying grayscale ML Raw on an external monitor? I keep seeing 5x in color, but cannot get grayscale to show.

Hello everyone,

     There's an odd spot between 23 seconds and 24 seconds of this clip. I've noticed it some of my footage. It might be sensor dust but I'm not sure. Is there anyway someone can take a look? The reason I'm posting it the same topic is it could be an artifact. Any help would be great. Thank you.

- Paul

Hello Danne,

    Ok I understand. I'm hoping this new way will avoid the artifacts. I will report back if the artifacts are in the clips or not. Will record at ISO 1600 and not crop mode. If I get a chance, I'll try recording 14 bit as well as 12 bit lossless for the same scene. I might try 14 bit lossless too since 14 bit does take a lot of card space.

- Paul

Hey Danne,

    I did some tests today but couldn't replicate the artifacts. I saw 3-4 dead pixels when recording all bit depths and even with vertical band fixing on there were still vertical bands. I think it's best to apply vertical bands correction only on clips that need it (unless there is a setting I don't know about). The dead pixels were there even though I had Bad Pixel Fix on and Aggressive. However, after my tests I read your recent response. I was using Crop Rec Module and Raw Video. Only using the Raw Video Tab, 3.5K raw is still possible with 1.63 crop. When turning off Crop Rec Module and just using the Raw Video Tab, I was able to record 10 bit lossless for a long time. 12 bit lossless wasn't as long as a record time as I had on the Experimental Build July 22nd on the Experimental Builds page. So, for my next testing, I am going to record 14 bit at 2:35.1 (1920x818), then when shooting 3.5K, will still use 2:35.1 (3520x1320) but with 10 bit lossless. I will report back here with the results. Hoping to work around this issue! Any additional feedback would be great. Thanks.

- Paul

Hey Danne,

    Thank you for the quick response. Ok I understand. I'm going to record a really long take in 12 bit lossless and 14 bit. I'll try 14 bit lossless and the other bit depths as well.

- Paul

Hello everyone,

     Forgot to mention I only recorded in 12 bit lossless, and forgot to test 14 bit. I'm going to take pictures of all of the settings and provide an MLV, DNG Sequence, and XQ file. I'm using MLV App. The only adjustments I'll use are Cinelog-C and lens vignette correction. I won't touch any settings in MLV App. The DNG sequence will be lossless. I'll post here when I have the files ready.

Hello everyone,

    I'm currently using Danne's October 15th Build: found on this page:

    I filmed at a park in Delaware on Monday 10-28-2019. I decided to record in ISO 1600 with an nd filter on (SLR Magic Variable ND MK2). Last weekend I went to a park in Pennsylvania and shot at ISO 100 with Danne's build, and got no artifacts/dead pixels/focus dots (whatever these artifacts are). No artifacts at all, a few clips had vertical bands.

    When I shot at ISO 1600 in Delaware, I now have artifacts in my videos, and even though I had 3.5K module enabled with 23.976fps override at 2:35.1, only 1920x818 was recorded when I used 5x crop. When I shot at ISO 100 I didn't have this issue. At ISO 1600, I did still get vertical bands on a few clips (both ISO 100 and 1600 I have had vertical bands on a few clips).

    So, I've tested the artifacts issue on 3 different days/shoots. I've found ISO 1600 1920 x 818 (no x5 crop) is where the issue occurs. What can I do to figure out this issue? Is it possible to share an MLV that has this issue and for someone to take a look? If I take pictures of all my settings, is there something I need to look for or maybe someone can take a look? I'm worried my camera might have an issue, but am not sure how to tell. Any advice would be greatly appreciated. Thanks.

- Paul

Hey Danne,

    I still have the July 22nd, 2018 1.2.3 Crop Rec 4K Build on my other CF Cards. This build is on the Experimental Builds Page found here:

    I'll see if I can reproduce the issue when I have some spare time. The artifacts occur with 1920x818 12 bit lossless ML Raw video with frames per second override on at exact fps and ISO 1600.

Hello domo94,

    I just sent you an email regarding the VAF-7D.

- Paul

Hello everyone,

     I tested Danne's recent build from October 13th, found here:

    I haven't encountered the artifacts at ISO 1600 with long takes. I used MLV App and tested 12 bit lossless and 14 bit lossless. Tested 3.5K and 1920x818 with frames per second at 23.976 and exact.

    It was really hot out, and in order to test ISO 1600, I had to use a variable nd.  I tried to reproduce the issue by shooting long takes out in the heat. The only issue I saw was vertical banding. Other than that there was some of lens flaring with the Canon 16-35 f2.8 Mark I.

    I'll have to test more, but so far I haven't encountered the issues I was having before.

    Also, before installing Danne's build, I uninstalled Magic Lantern (was using the July 22nd, 2018 Crop Rec 4K Experimental Build) by formatting both the SD and CF card. I used Sandisk Extreme Pros. I then used a card reader to copy the files from Danne's build to both memory cards. Then I updated the firmware, rebooted, and experienced a few issues with loading modules. There were errors. Fortunately I was able to get the modules working by loading mlv lite. I will provide a link when I get a chance of all the settings I used. I decided to restore ML settings to default, then changed settings from there. There were no error files on my SD card or CF card.

    Thanks for all of your help. I'll continue testing, but so far, so good :)

    - Paul

Hey Danne,

    Ok I understand. I will test a new build soon as well as 14 bit on the current build. I'm hoping there is a way to fix this issue without a focus pixel map. If the same artifacts occurred in Canon 7D ML Raw, and there is a fix for that, then there should be a solution. Did you by any chance check the ML settings I have in the Google Drive link? Maybe it's a setting in the current build I'm using?  I'll make sure to do the tests though. It will be great to avoid this issue in the future.

    Oh and one other idea. Do you know if reflashing the 1.2.3 firmware would make any difference?

- Paul

Hey Danne,

    I haven't tried a your new build yet, but I noticed something. The artifacts I'm having with the Canon 5D Mark III 1.2.3 Experimental Build July 22nd, 2018 are the same exact issue with the Canon 7D when shooting slow motion ML Raw 14 bit. This happened with 2 different Canon 7D ML Nightly Builds. However, disabling cold pixel fix in Batch MLV fixed the issue. Another resolution was passing through original raw data without processing. I believe disabling vertical stripes fix would solve the issue as well. So, I'm starting to think there is a way of solving this issue without focus pixel maps. If the issue is resolved with the Canon 7D ML Raw 14 bit, then Canon 5D Mark III 12 bit lossless should have a solution. I've tried disabling cold pixel fix, disabling vertical stripes fix, both fixes combined, and passing through original raw data. None of these solutions which work with the Canon 7D work with the Canon 5D Mark III. Here is a link to the post I made on this forum about the Canon 7D:

    Here is a link to a long take a couple days ago with the same artifacts issue with the Canon 5D Mark III:

Hey Danne,

    I just sent you a message. I am using the 4K Crop Record Experimental Build for 5D Mark III 1.2.3 July 22nd, 2018. I messaged you the settings I use as well. Here is a link to the settings and build I'm using:

I noticed this issue again from filming yesterday. The artifacts were in my footage, and it was a long take. Just like the choir concert... Might have to do with recording too long or overheating.

- Paul

Hey Alex,

    I thought it was a bit odd to face this issue with the 5D Mark III. I messaged Danne and dfort and they gave me advice on how to fix this issue. I was told they are focus dots. In MLV App, with the fpm file installed, I chose Fix Focus Dots. This is the experimental build, the most recent one. Are you saying I won't face this issue with a nightly build? I'll make sure to check the (lv_af_raw) settings.

If you already mapped your bad pixels - in the FPM file - you know what you have to do: shift them into the right place.

In regards to shifting the dots in the right place, is there a certain order you're referring to?

     Thank you for your input Alex. I do appreciate it.

- Paul

Hey Danne,

     No need to apologize. I really appreciate your help. I'm on Windows and have used batch_mlv_in-out before. I'll try your fpm file next to the MLV file and see how it goes. Should I be worried about a faulty sensor? I found it strange at ISO 1600 to have so many focus dots. It does seem fishy.

- Paul

Hello Magic Lantern Community,

     I've been editing a choir concert lately, and have noticed several Focus Dots from 1080p 12 bit lossless raw video from the Canon 5D Mark III. I used ISO 1600 and a Sandisk Extreme Pro CF Card. I messaged Danne and dfort, and they have helped me a lot. I created a fpm file with coordinates of where the focus dots are. I used Fix Bad Pixels On, Aggressive, and Interpolation 3. Also, I have Fix Focus Dots On. However, I keep seeing more focus dots in my footage and have had to move on and edit the project with how the footage currently is. My questions for the community are: How can I avoid this in the future? & What is the best way to remove Focus Dots? Here is a link to the files:

    Any input on this would be greatly appreciated. Thank you.

Hello pedz,

    Please be careful when purchasing memory cards from Ebay. There are a lot of fake memory cards being sold.

   I've purchased memory cards from Lens Authority. Here is a 128 GB Sandisk Extreme Pro CF card used on their site:

    You can also try looking for used memory cards on BH Photo or Adorama or Amazon. Be careful with Amazon because there a fakes sold. Usually you can tell which seller is legit or not.

    Sandisk Extreme Pro SD Cards are great for Magic Lantern. Should be fast enough for proxy recording.

   Any other questions please let me know.

General Help Q&A / Re: 60D SD card size max?
« on: November 12, 2018, 11:22:42 PM »
Hello gwizz00001,

     I used a 64 GB Sandisk Extreme Pro 95 MB/SEC card for an event and the files were all corrupted. I was able to find a software to fix this, but now I don't go over 32 GB cards for the Canon T3i. Different camera than 60D but I believe it's the same sensor. I also used a Transcend SD card with the Canon T3i and couldn't recover a file and had to reshoot it. Just my 2 cents. Hope this helps.

Hey Danne and Kharak,

    Thank you for responding. I found disabling vertical stripes fix did not remove the artifacts, but disabling cold pixel fix did. Just to make sure, does the Canon 7D ever get cold pixels? I've gotten dead pixels and hot pixels, but I'm not familiar with cold pixels. Is cold pixels and dead pixels the same? I think Adobe Camera Raw removes hot pixels, not sure about dead pixels. Anyways, here is a link to the tests I did regarding your (Danne) recommendation:

     If anyone can tell me whether the 7D has cold pixels I would appreciate it. Thanks.

« on: September 08, 2018, 08:44:58 AM »
Hello everyone,

    I found a solution. When using batch_mlv_in-out to convert MLV files to DNG sequences, I would hit R on my keyboard for Run. This includes all of the processing. For some reason, there are artifacts when shooting 59.94fps raw video in the DNGs. However, if I enter 3 on my keyboard, this enables "pass through original raw data without processing, it works for lossless or uncompressed raw" there are no artifacts. Here is a link to the files if anyone would like to view:
