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.

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.

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.

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: crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Oct15.5D3113.zip found on this page: https://www.magiclantern.fm/forum/index.php?topic=23041.msg216899#msg216899

    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.

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:

https://builds.magiclantern.fm/experiments.html

    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.

- Paul

Hello domo94,

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

Hello everyone,

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

    https://www.magiclantern.fm/forum/index.php?topic=23041.msg216899#msg216899

    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

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:

https://www.magiclantern.fm/forum/index.php?topic=22771.msg205825#msg205825

    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:

https://drive.google.com/open?id=1MtVsdi6GTOsyAUkSYOAjkF7ip8vXPGRc

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: https://drive.google.com/open?id=1gi9tnSDQenCl32aRLhaXNFLlRqpyWdWa


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

You're welcome govindvkumar!

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:
https://www.lensauthority.com/products/sandisk-128gb-extreme-pro-udma-7-compactflash-card

    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.

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.

- Paul

Hey Danne,

     Ok great. Thank you for the quick response.

- Paul

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: https://drive.google.com/open?id=19e4pcwYq-1h2h47jUFN8okjT53zNpVG-

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

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: https://drive.google.com/open?id=190chDIMC3lxG0FGZ6j1znpWGlwSi8lsI

Hello everyone,

    I have noticed something odd happening with my Canon 7D when shooting 60fps raw video with the VAF-7D filter. Lenses used are the Canon 100mm f2.8 USM and Nikkor 35mm f2 ai. This could be because the VAF-7D wasn't designed for 60fps in 720p, or the VAF-7D filter small scratches are showing, or the sensor is scratched (I wet cleaned once and while back. I now just stick with the rocket blower). I'm hoping you can look at a few photos and a video so I can pinpoint the issue.

Here are a few links:

Photos: https://drive.google.com/open?id=1LmvzCQ-Bi6sBGbgn2Z0Zut8ufz4fv2VM

Video: https://vimeo.com/207039459

           https://www.youtube.com/watch?v=B-YXux3ofjU

The artifact can be seen in the video in the beginning where the kid is throwing candy from the back of the truck. The artifact is near her face.

As for the photos, I showed wide shots, and then zoomed in shots. It's a bit difficult to tell, but I did my best showing it. I'm hoping there is a way to remove it in batch_mlv_in-out. Sorry if this is vague, please let me know if there is more information needed, or more examples. Thank you.

Hello Majkovic,

   I really enjoyed this video you created. I am intrigued by the colors, the extent of dynamic range achieved, and music choice. I look forward to more work from you. It's definitely good to just go out and film and clear your mind. Filming can be super relaxing when it's just myself out in nature. I can relate to you on this.

- Paul

Hey Nickm45,

    Sometimes when skies are blown out, especially the sun, you'll have magenta (or purple?) in the highlights. You'll need to fix when converting .mlv files (whichever ones have the incorrect white level) to dng sequences. So, click this link:  https://bitbucket.org/Dannephoto/batch_mlv/downloads/ , then download batch_mlv_in-out. Then, extract the .zip file. I still don't know if you're using Mac or Windows, however here are the instructions for white level fix in Windows. It should be similar for Mac. Click on the batch_mlv_in-out folder. Inside you'll find batch_mlv.bat. Right click it, and choose open. You'll be prompted with a window that is asking for your input folder. Choose the destination where you have the .mlv files (keep them inside a folder). Next, type 17, then type Enter. This will ask you to specify the white level. From there, type 12,000. Then, type Enter. Then type R (for run batch_mlv). Then where your destination folder is, there will be a new folder created called ORIGINALS. There also will be separate folders for each dng sequence. Then, you can create a folder called DNGs, place all the dng sequences folders inside the DNGs folder. Then, you can import the DNGs folder, which will import all the dng sequences folders. I suggest using the SmartImport2 After Effects Script. This will save you a lot of time when importing dng sequences. I have provided a link below. Also, I suggest purchasing Cinelog-C, which works with Adobe Camera Raw. I will provide a link below for you to check out. Then adjust white balance for any dng sequences that need it (you should try to custom white balance with a grey card in camera if possible), add any lens corrections (for vignetting and distortion), make sure Cinelog-C is applied, save a preset for your settings, and add the preset to any other dng sequences you shot at the same time and place. You can create a folder before importing for a codec you wish to use. I suggest ProRes 4444 XQ or GoPro Cineform 12 bit RGB, or Avid DNxHR. For each codec, with Cinelog-C added in Adobe Camera Raw, you will be able to recover highlights. After you have adjusted all of your dng sequences in Adobe Camera Raw, and have chosen a codec in SmartImport2, this script will create dng sequences in compositions. Then the compositions will be in your After Effects Render Queue with the codec you have chosen. Click Render Queue. Also, make sure in After Effects, in Preferences, set the frame rate (aka fps). For example if you shot in 23.976 fps, then enter that. This will set the fps for all of your future compositions. If you have different clips with different fps, you can change the frame rate in Preferences after you have imported all dng sequences for that fps. For example, if you have 5 .mlv files with a fps of 23.976, then add 23.976 into Preferences. If you have 5 more .mlv files with a fps of 1, then enter 1 for frame rate, then import those dng sequences, and compositions will be created with 1 fps. You can keep each fps in different folders once you process the .mlv files in dng sequences. I usually have a 23.976 fps folder and a 59.94 fps folder. Also, SmartImport2 works with audio as well. I realize this is a lot of information, and some of it might be confusing. You will get the hang of it if you keep shooting and editing. Just stick with it because the results are amazing, trust me. Please let me know if something I said was confusing. I hope this is helpful for you, and feel free to post more about the purple colors issue you are having.
