HDR script keep original framerate (Mac)

[Danne]

Been testing enfuse and align_image to refine some ideas around HDR recording and after some tinkering I managed to get some decent results. For now it works with MOV(H.264) files. The script processes frames in a consecutive manner so the original fps will be kept. Now this doesn´t mean HDR will suddenly work with 24 and 25 fps without ghosting and so on but as the script will use align_image most movement will be aligned so feel free to test lower framerates such as 24, 25 and 30 fps.
The script will actually work three files creating a new one then proceed to the next three files creating the next frame etc. Why three? I can´t combine enfuse and align_image and just process two files after each other without having flicker going on(some interpolation caveat).

The script will create two files. One called HDR_tblend_ and the other one HDR_enfuse_. This is for comparison reasons. The HDR_enfuse should look better. The tblend filter is used with ffmpeg so that one isn´t even touching enfuse/align_image. Recommended to film with 50 or 60 fps but feel free to test slower framerates as well.

You need following installed for the script to work:

I really want to try this but it seems pretty hard. I'm basically retarded.

Here comes the dummy solution  :

Installing dependencies:
1 - Open up terminal and copy paste following into it:

Code Select Expand

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install exiftool
brew install ffmpeg
brew cask install hugin
press enter


Running the script:
1 - open up terminal
2 - write cd hit space and drag a folder with MOV files onto terminal after the word cd
3 - Press enter
4 - Copy paste the entire script below into terminal and hit enter if needed(sometimes it starts without)

So happy to see good old HDR still being in the works...  gonna definitely try this one out and thanks @Danne!

You're welcome man

Don't that this the wrong way but why reinvent the wheel , unless you like scripting

This been here since 2012 , thou it's for Final Cut Pro X work with h264 , ml raw converted to prores , works will .

[Danne]

He's using the old principle loosing half of the frames(at least my understanding from reading the post, didn't test). I am grabbing the following frame(consecutive) thus retaining original framerate. This effectively means you could shoot in 24fps without the need for interpolation of lost frames. I am also using align_image which will makes a massive difference when reducing ghosting.

[Danne]

Here´s another script roundtrip to obtain a flicker free HDR output using ffmpeg tblend average filter instead of applying enfuse. I´m using a combination of hugin align_image and then I crop and scale back to original aspect ratio leaving a prores file ready to use. The issue with enfuse is that interpolation of borders will cause flicker and tblend does not:

I´m curious if 30 fps could work somewhat ok with this script so if there could be some testing around that it would be cool.

[Danne]

Here is yet another take to HDR recording. I still focus on MOV and this time in conjunction with the very nice function fps override. Since it´s possible to override 1920x1080p H.264 MOV thanks to A1ex reverse engineering sourcery let´s try what can be done to reduce movement/ghosting and still achieve some good quality merged HDR output with some decent 1920x1080p footage.

This is needed:
Only thing needed are one or more MOV files recorded in HDR mode in regular mv1080p with fps override set to 38. End result will become merged mov 24fps files with nice quality and flow to it. Except for aligning and rescaling through hugin and ffmpeg(tblend filter) this script will also use ffmpeg minterpolate filter to drop frames with smooth high quality results. FFmpeg end part looking like this:

Code Select Expand

ffmpeg -r 38 -i %06d.tiff -vcodec prores -pix_fmt yuv422p10le -vf "minterpolate='fps=24'" HDR_enfuse_$(ls *.MOV | head -1 | cut -d "." -f1).mov

Added to this script are safeguards since multiprocessing sometimes seems to skip or loose a few frames. This will be checked upon now so should work more reliable.

Run the following script inside a folder with 38fps MOV files:

Code Select Expand

#Scripts for testing purposes
#Drop HDR MOV files into a folder and run the script i terminal from within the folder with MOV files. Hit enter when prompted
#The script will create three different types of HDR files. Please compare and report results
#All scripts combines consecutive frames so original fps is kept

This is so gnarly, @Danne and can't wait to get my hands dirty and dandy on this 38p hack of yours!

[Danne]

This script will run up to 4 processes simultaneously. Terminal will cat out subprocessing scripts and when all is done clean the folder leaving all files merged and ready. If any dependency is missing you will be asked to install what´s missing.
You will also be asked if you want to specify in and outcome of fps or leave it on auto. Why the in and out fps? Well, let´s say you record files in 30 or even 38 fps. Now you a can reduce frames nicely to 24 fps using ffmpeg minterpolate filter.
Inside a folder with HDR MOV files run this script:
(using pastebin, too many characters...)

Seriously you STILL just somehow manage to find ways to continue in maximizing the versatility of your amazing scripts all together.

It is extremely intriguing to know that we can finally be able keep the HDR fun alive and well lit even in its original frame rates.

Especially to go from 38p to 24p while in H.264 format. I mean that's just unheard of. There's a saying that goes 'legends never die' and that's the true legendary in you, @Danne!
