GoPro Studio for Linux tips and tricks

####GoPro Protune correction, timelapse assembling, fisheye removal, slow motion, 4:3 to 16:9 and motion blur in Linux OS - GoPro Studio for Linux - KDEnlive, FFMPEG, ImageMagick, Mencoder and Python!

GoPro Studio has been tremendously useful for GoPro users, but not all GoPro users can enjoy the tool, there is no GoPro Studio for Linux. So some users made their ways to emulate GoPro Studio on Linux.

This guide is more than GoPro Studio, is a must read guide for Linux and GoPro users.

The main features of GoPro Studio are:

  • Convert and edit Protune footage and apply Protune effect.
  • Convert 4:3 footage to 16:9
  • Slow motion
  • Image control.
  • fisheye removal.
  • Assemble pictures for timelapse, and include all the settings such as resolution, frame rate, motion blur and remove fisheye.

Here you will find markdown files explaining how to do all of the GoPro studio Windows/mac features... in Linux!

#####Other

Use VLC to play the rad footage. VLC is an open source and free multimedia player software for all platforms, including linux.

To install it, just run:

sudo apt-get install vlc

#Fisheye correction using Python / KDEnlive.

###Python You can find a file called fisheye-video.py, this is for correcting gopro fisheye footage using Python. In line 7, replace XXX by the folder, XXXX by the video ID and user by the user where is the SD connected.

###KDEnlive There is an effect called Lens Corrector in KDEnlive which corrects the fisheye.

The presets I use for correcting the fisheye are: #####HERO2:

  • Horizontal center: 450
  • Vertical center: 619
  • Center correction: 288
  • Edges correction: 456
  • Brightness: 562

#####HERO3:

  • Horizontal center: 378
  • Vertical center: 619
  • Center correction: 230
  • Edges correction: 300
  • Brightness: 562

#####HERO3+Black SuperView:

  • Horizontal center: 430
  • Vertical center: 619
  • Center correction: 270
  • Edges correction: 456
  • Brightness: 562

The presets result may vaty between resolutions, adjust the lens corrector for the perfect video correction.

##For photos

There is nothing worse than getting a fisheye picture with a GoPro that ruined your shot. Instead of cropping, use ImageMagick: Note: It does not make sense to correct the photos of a timelapse, makes sense to correct the timelapse video instead! First, you will need to make the AAAGOPRO folder your work directory Replace user by the linux user and AAAGOPRO by the folder of the GoPro.

cd /media/user/8765-4321/DCIM/AAAGOPRO/

In your AAAGOPRO folder you should have photos in .JPG, use ImageMagick MOGRIFY:

mogrify -distort barrel "0 0 -0.3" *.JPG

It overwites all the .JPG files and correct them! #####Here is a demo, click image to enlarge!:

#4:3 to 16:9 video conversion

If you record in 1440 or 960 video resolution to have more FOV in the top and the bottom, when you edit the footage you will have black bars at the sides, to convert the footage to 16:9 like in GoPro Studio, we need FFMPEG.

Here is the command to convert 4:3 to 16:9: First, you will need to make the AAAGOPRO folder your work directory Replace user by the linux user and AAAGOPRO by the folder of the GoPro.

cd /media/user/8765-4321/DCIM/AAAGOPRO/

Replace XXXX by the gopro video number

#KDEnlive Protune filters for GoPro video

KDEnlive is an opensource and free non-linear video editing platform for Linux. A Linux and GoPro user Hajo shared a way to edit and convert GoPro Protune footage with KDEnlive, the alternative for GoPro Studio (which is only available for macosx and windows). He coded a XML preset which you can install in your KDEnlive effect bundle. Below are two files:

See a demo video

###Installation

######to install the presets, download this gist, unzip it, and copy the two XML presets to your desktop or somewhere where you can remember the path. You will need to move the two XML files to ~/.kde/share/apps/kdenlive/effects/. Below there is a UNIX mv command to move the files to the KDEnlive directory, remember to replace 'path/to/preset' by the path to the XML preset.

mv path/to/preset/gopro-protune-indoor-kdenlive.xml ~/.kde/share/apps/kdenlive/effects/

mv path/to/preset/gopro-protune-outdoor-kdenlive.xml ~/.kde/share/apps/kdenlive/effects/

####MenCoder as a GoPro timelapse assembler and ImageMagick as a Motion blur tool for timelapse

Another of the useful features of GoPro Studio is that it assembles the pictures shot with your gopro in a movie file at a certain frame rate. This can be achieved using the opensource free tool mencoder. (And previously FFMPEG!) And motion blur for timelapse using ImageMagick First, you will need to install MenCoder. If you want to add motion blur, download ImageMagick Or, use the command line to install MenCoder: #####Ubuntu:

sudo apt-get install mencoder

Then, connect your GoPro via USB or connect the microsd to the computer. You will need to list the commands, but first, go to the XXXGOPRO folder. Replace user by your linux username and XXX by the gopro folder number

cd /media/user/8765-4321/DCIM/XXXGOPRO

Then, generate the list:

ls -1tr > gopro.txt

Then you can assemble the timelapse, fps=20 indicates the fps of the timelapse:

mencoder -nosound -ovc lavc -lavcopts \
vcodec=mpeg4:mbd=2:trell:autoaspect:vqscale=3 \
-vf scale=1920:1080 -mf type=jpeg:fps=20 \
mf://@gopro.txt -o gopro.mp4

####Motion Blur If you want to apply motion blur:

Use ImageMagick, run this command BEFORE Mencoder.

Replace user by your linux username and XXX by the gopro folder number

convert /media/user/8765-4321/DCIM/XXXGOPRO/*.JPG -delay 10 -morph 5 [port]/DCIM/XXXGOPRO/motionblur%05d.jpg

It will take some minutes to convert the pics...

#Slow motion using FFMPEG

One of the killer features of GoPro studio is the ability to slow down 60fps/120fps/240fps GoPro footage. To do so in Linux you will need FFMPEG. Installation of FFMPEG already explained in other files.

###How-to:

Lets see, you have shot a 720p 120 fps video, you can slow it down to 20% maximum, more % will result a crappy footage.

  • 120fps is 9.6/1
  • 240fps is 5/1

So, replace /media/konrad/8765-4321/DCIM/143GOPRO/GOPR2687.MP4 by the GoPro MP4 footage location, for instance the SD card (hint: drag and drop the video to firefox, then copy the url but delete the file:/// protocol :) ), the output slowmotion file will be generated in your desktop.

ffmpeg -i /media/konrad/8765-4321/DCIM/143GOPRO/GOPR2687.MP4 -r 25 -vf "setpts=(9.6/1)*PTS" -sameq -vcodec libx264 ~/Desktop/slowmotion1.MP4

Now you got a long clip which is slowed down, its time to trim it into a shorter one for easy post processing:

-ss indicates the start (HH=hour, MM=minute, SS=second) and -t indicates the total duration of the video, not the end.

ffmpeg -i ~/Desktop/slowmotion1.MP4 -ss HH:MM:SS -t HH:MM:SS -sameq -vcodec libx264 /media/konrad/8765-4321/DCIM/143GOPRO/slowmotion-1.MP4
rm ~/Desktop/slowmotion1.MP4

It deletes the old long video too!
