Here is a cropped screenshot from when i was viewing it in MLVApp (unedited)





The spokes more so on the right seem to have orange and blue stripes. Not sure if it's an exposure issue, a bug, and if it can be corrected. I don't know what to call this problem, the zebras looked fine on the spokes and i only made an exception for the bright sky. Probably struggling with a narrow transition from highlights to darks. Any ideas?

EDIT: Duh, it's moire. Not sure if there is something to help control it in ML. If i can't find a solution then i need to get a much wider lens and shoot in 5x crop (pans would be super shaky on my 35mm x5!). Kind of an annoying workound... again suggestions are super appreciated!

Yes, a few frames or a MLV would be great. Recently rewrote aliasing handling to this script meant to be used in Mlv App but there are a few quirks with command script handling in there atm.

This kind of moire is interesting; mind sharing a few DNG frames?

These might help:

Here is the MLV. Kind of embarrassed about this shot to be honest, didn't turn out the way I wanted but it's going to be re-shot anyways  :-\ ignore my stupid voice

Wow that's pretty cool! Seems to have desaturated the moire but i would still like to get rid of the stripes. Thanks for the tip! Definitely less noticeable.

Downloading the mlv. Rather big. I suggest you shorten it in Mlv app and upload a smaller MLV file. Think something like 50 frames will do.

Danne does it again with his magic scripts.

Big improvement. Don't notice it until you zoomed way in. Wonder what it looks like in motion. Aliasing artifacts are uglier in video than in stills.

Right now I´m trying several passes on a file. Takes a while to perform testing but I´ll upload any improvements...

whoa thank you so much for tackling this! is this something that will eventually be part of MLV App? and sorry for the file size, I'm still new to this and wanted to leave it untouched in case I did something wrong that i'd be unaware of.

Yes, as a post script solution. I will try and refine it a little further and hopefully masc fix implementation after holidays.
It's a processor heavy process but I guess it will be worth the extra time for critical recordings.

ok cool, I really love you guys and what you're doing. wish I could give something in return.

I'm also looking at Mosaic Engineering anti-aliasing/anti-moire filters but they're out of stock.

Do we have to use it with MLVapp Or can we execute it by itself?

Here is a version of Mlv App with the tif_clean script included.
Just select the script from within export settings then export to any format:


MLV_App_tif_clean.app
https://bitbucket.org/Dannephoto/mlv-app-danne/downloads/MLV_App_tif_clean.app.zip

If anyone tests please share results. For best results use it on footage with moderate motion but do test any footage to see if it helps...

Is this also available for Windows?

This is quite amazing Danne. What method is it using? It's like Tlsophote, where he has a edge-detection algorithm and them blurs the areas or it's something more complex like superresolution?

@50mm1200s
When it works it can be really good.
It's an idea based on a1ex thread pointed at above:
https://www.magiclantern.fm/forum/index.php?topic=20999

 In my script I use programs based on this:
https://www.magiclantern.fm/forum/index.php?topic=21089.msg193622#msg193622

How does it work? Speculating enfuse average surrounding images yielding the positive side effect of reducing aliasing rather effectively.
Caveat. Motion will increase the effect while to much motion might cause side effects as bluriness. Can be reduced by weighing more pixels from enfuse base image which my latest script does atm.
Sorry, only mac for now @LICK_THE_BUTTER

This is really amazing, Danne!  I can't wait to test it on Win x64.  Now that the 100D works so well with the overclocked SD-card interface, I expect your script to be God sent for improving moire at higher frame rates in critical high-contrast situations.  Congratulations to another excellent result!

Yes, overclocking is great.
I would recommend anyone wanting this for windows to check into powershell or cmd scripting. I could give some pointers about the general idea but don't see myself digging into windows anytime soon.
