Reframe360 XL

This plugin is an extension of the excellent Reframe360 (http://reframe360.com/) plugin by Stefan Sietzen. When Stefan discontinued the project and released the source code, I got to work to add features and fix bugs and it became Reframe360 XL. XL is used to point out that new features were put in place and is also a nudge to the excellent SkaterXL game.

New features and bug fixes:

• Support GoPro Max pseudo Equiangular cubemap files
• Support Youtube Equiangular cubemap files
• New animation curves implemented (Sine, Expo, Circular)
• Apply animation curves to main camera parameters
• Fix black dot in center of output
• Update to latest libraries and Resolve 17

Enjoy!

GoPro Max import

If you own a GoPro Max I wrote two "proof of concept".
For converting the native .360 files into a standard equirectangular clip with FFmpeg I wrote a filter, see https://github.com/eltorio/FFmpeg (I already made a pull request on the main FFmpeg repository).
For dealing -almost- directly in DaVinci Resolve 17 studio I wrote an openFX plugin, see https://github.com/eltorio/MaxToEquirectPlugin

Building on MacOS (Intel and Apple Silicon)

• Build tested on MacOS 11.2.3 / XCode 12.4
• Install latest XCode from Apple App store
• Install Blackmagic DaVinci Resolve from Blackmagic website (studio version)
• clone glm repository https://github.com/bclarksoftware/glm.git
• clone this repository
• and build

cd reframe360XL
make

Building on Windows 10

• Build tested with VS2019 community edition and CUDA Toolkit 11.2
• You need to have python installed and working for generating OpenCL and Metal embedded kernel source code
• If you have a different CUDA Toolkit version open the vcxproj file with a text editor, search for 'CUDA 11.2' string and correct it

Building on Linux

• Resolve only works with x86_64
• Build tested with Ubuntu 20.04.2 / NVidia Cuda 11.3

Binary for MacOS

• install bundle
• uncompress it and puts it to /Library/OFX/Plugins
• Metal and OpenCL are tested

Binary for Windows

• install bundle
• uncompress it and puts it to C:\Program Files\Common Files\OFX\Plugins\
• only CUDA is tested (OpenCL seems not working with NVidia drivers >= v465)

Binary for Linux 64

• install bundle
• uncompress and put the bundle in /usr/OFX/Plugins/
• the 3 architectures are bundled in the same «universal» plugin
• only CUDA is tested (OpenCL seems not working with NVidia drivers >= v465)

Trying with DaVinci Resolve 17.2 studio with standard equirectangular 360 movies

• If you have an equirectangular movie just import it in the timeline
• Apply the Reframe360 XL filter
• Choose Equirectangular as the input format (default)
• Reframe

Trying with DaVinci Resolve 17.2 studio and GoPro Max .360 files

First divide the .360 files in two movies

Today DaVinci Resolve does not support dual video stream in the same MP4 container
So I divide my .360 in two files with ffmpeg
Front stream is 0:0 in ffmpeg

FILE=in.360
ffmpeg -y -i "$FILE" \
    -copy_unknown -map_metadata 0 \
    -map 0:0 \
    -map 0:1 \
    -map 0:2 -tag:d:0 'tmcd' \
    -map 0:3 -tag:d:1 'gpmd' \
    -map 0:5 \
    -metadata:s:0 handler='GoPro H.265' \
    -metadata:s:1 handler='GoPro AAC' \
    -metadata:s:d:0 handler='GoPro TCD' \
    -metadata:s:d:1 handler='GoPro MET' \
    -metadata:s:4 handler='GoPro AMB' \
    -c copy ~/Desktop/temp360/out-p1.mov

Rear stream is 0:4 in ffmpeg

FILE=in.360
ffmpeg -y -i "$FILE" \
    -copy_unknown -map_metadata 0 \
    -map 0:4 \
    -map 0:1 \
    -map 0:2 -tag:d:0 'tmcd' \
    -map 0:3 -tag:d:1 'gpmd' \
    -map 0:5 \
    -metadata:s:0 handler='GoPro H.265' \
    -metadata:s:1 handler='GoPro AAC' \
    -metadata:s:d:0 handler='GoPro TCD' \
    -metadata:s:d:1 handler='GoPro MET' \
    -metadata:s:4 handler='GoPro AMB' \
    -c copy ~/Desktop/temp360/out-p2.mov

Second import them in a timeline

• Import your front and rear movies
• Create a 4096x2688 timeline
• Insert front movie in the V1 channel (and the audio)
• Apply a translation in the inspector y=+672 for putting the front camera on the top
• Insert rear movie in the V2 channel (without the audio because it is the same)
• Apply a translcation of y=-672 for putting it on the bottom

Third create a compound clip and a new timeline

• Create with this two clips a compound clip
• Create a new timeline 4096x2688 input and UHD or HD output depending on what you want
• Insert your compound clip in the timeline

Finally apply the filter

• Apply Reframe360XL
• Use GoPro Max as the Input Format
• Reframe

Sample DaVinci Resolve 17.2 studio project

• Just restore the project archive Reframe360XL-GoProMax-test.dra from the repository for testing a sample GoPro Max to your Resolve database
• It contains only 2 clips of 15s, they were generated from a still taken from my GoPro Max at take off with my daughter front of the mont Blanc in the Alps.
