General Chat / Cinema wide aspect crop question

« Last post by ItsMeLenny on Today at 10:41:53 AM »

A question for anybody who has the correct answer;

When I see behind the scenes stuff for movies, they have their 16:9 monitor with multiple crop marks, but for the "cinema wide" crop mark (greater than 2:1 (the 2.39:1 or what not)) it is never positioned at the centre vertically...
Why?

Scripting Q&A / 3k script for nightly build

« Last post by lightspeed on Today at 09:34:21 AM »

I have noticed a conflict with the crop_rec and mv_lite for the bit rate.

therefore I do not turn on the crop_rec module. I have a 2.5k script that enables the crop but when I try to change the resolution to 3k I can not. can someone tell me what I'm doing wrong or tell me how to write a script to enable 3k.

thank you for the help.

Share Your Videos / Re: Magic Lantern Cinema Camera - Dual ISO without aliasing & without quality loss!

New build for 700D:
https://drive.google.com/open?id=1qnhTArl_DsfyHaLLfQJDPbLD85OBtMxB

-White Level is correct for Analog gain (thanks Danne)
-Now once you load sd_uhs it will patch during start up, no need for script and enabling it manually (thanks Danne)
-There is no 11-bit lossless , it will start from 10-bit lossless to 8-bit lossless depending on ISO (I removed 11-bit lossless to enhance recording time in ISOs 100-800)
-Included Dual ISO fix for ISOless 8 & 15
-Shutter flickering has been fixed (Thanks a1ex)
-Removed Crosshair in crop_rec
Note: Once you enable crop_rec and change Y or X resolution the actual bit-depth Will be 10-bit lossless , there is no 14-bit lossless (You should always select 14-bit lossless from mlv_lite if you want to use crop_rec in this build , and the final bit-depth will be 10-bit lossless , I did this to enhance recording times and I couldn't figure out how to chose between 14-bit to 12-bit lossless when using crop_rec) and once you disable crop_rec you can use the bit-depths from mlv_lite normally .

How to use 1x3 Binning:
Load crop_rec and restart the camera, activate crop_rec , go to crop_rec submenu by pressing Q button , chose 1x3 Binning , press Menu button to refresh LiveView , That's it! --> To increase the Vertical resolution Just change Y resolution to 2214 (Sweet Spot) and refresh LiveView by pressing Menu button and getting back to LiveView.

Note 2: When you do any change in crop_rec you Must/Should/Have to refresh the LiveView manually ! How? by pressing Menu Button and going back to LiveView otherwise your settings will not be applied , if the settings were saved and crop_rec was activated and you turn on the camera You should also make a refresh .

You can do a build for the 650D Canon, I would like to try all this on my camera and make better videos.

General Development Discussion / Re: The MLV format

« Last post by Ilia3101 on Yesterday at 05:17:44 PM »

How cool is that. I guess dng or tiff into mlv would be really convenient here. Or even jpg h264 maybe?

I saw in MLV headers that it can have h.264, but IDK if it has ever been tested or put to use (MLV App certainly doesn't handle h264 MLVs ). DNG or cr2 would be easiest to convert to MLV though, especially if it is one of the already supported ML cameras, and masc found some nice libraries we could use.

The library also seems like a good idea but I have little experience i this field. Maybe contact g3gg0 and a1ex directly too?

Yeah I guess I should reach out to them. I'm just not sure about the licensing, I remember loads of something about Martin Herring's Footage app (Footage was completely closed, this library WILL be open source, but I would want it to be usable in proprietary software). As MLV headers are LGPL it should techincally be allowed... as long as raw_info can be dealt with, maybe using byte offsets

Would be nice to see resolve and premiere implementing mlv support .

It would be so satisfying if any of the industry giants were to implement MLV support. Maybe this is wishful thinking though

You are correct, processing internally always happens in the same order.

Cool! Mac users would love this . Hopefully linux users find it useful and could maybe post some examples.

Anyone is welcome to have a go at compiling it, you'll need Gtkmm library, maybe homebrew will let you install it.

Hello? guys.
Maybe someone can help me. I'v found some kind of hot pixels. "Fix bad pixeles" didn't help.
This is 0,5 speed of 1920*1080 11-8 bit raw from 5dmIII with magiclantern-crop_rec_4k.2018Jul22.5D3113 firmware.

when apply luts, selecting log type, and white balancing, does it matter what order I do these in on mlvap?

From my testing, it seems like whatever I select, everything comes out the same.

General Development Discussion / Re: The MLV format

« Last post by Danne on Yesterday at 08:53:59 AM »

But first, I want to make a raw to MLV converter that converts other raw video formats or photo sequences to MLVs, so I can use MLV App with them.

How cool is that. I guess dng or tiff into mlv would be really convenient here. Or even jpg h264 maybe?

A small gift to the Linux users here... MLV Stitcher

Use case: Shoot in crop mode on a tripod, move the crop window around to capture a larger area of the sensor in a few separate shots, then combine those separate shots using this little app to create a new, higher resolution MLV!

Based on MLV App code, it can import multiple MLVs, move them around, crop them, and stitch them together. Has feathering for smooth transitions, exposure adjustment and difference blending to make aligning easier.

I will not continue as there is too few real life use cases. I also used Gtkmm for the interface, painful to use crap.
