PNG2MP4_ffmpeg

This python script converts image folders to .mp4 videos.

Thanks to great compressibility options your data can be stored in a more compressed way!

Script based on:

• 1. ffmpeg encoder to create videos which means high efficiency.
• 2. MPI library to parallelise a task for multiple folders.

How to Install

Linux

1. Install Miniconda

bash ./Miniconda3-py38_23.5.0-3-Linux-x86_64.sh

conda activate

2. Install MPI4py

pip install mpi4py

3. Install ffmpeg

conda deactivate

sudo apt install ffmpeg

Windows

(minimal)

(easy)

1. Install Miniconda
2. Start Anaconda Prompt (miniconda3) as administrator
3. Install MPI4py

conda install mpi4py

3. Install ffmpeg

conda install ffmpeg

How to Use

For Unix (Linux) sustems

To start a script, run from preferred command line, see next example:

python /mnt/path_to_script/PNG2MP4_ffmpeg/MPIvideomakr.py 6 /mnt/path_to_target/pics/ /mnt/path_to_save/vids/

Where 6 in this example shows amount of cores that will be used by script.

For windows:

Start a script with

python /mnt/path_to_script/PNG2MP4_ffmpeg/MPIvideomakr.py 6

(To minimise typing type "python ", copy and paste path to MPIvideomakr.py and type amount of cores(6 in the example above) )

Then an interactive window will suggest to choose a folder with tests with images.

Second interactive window will ask for a folder where to save videos.

Note

Warning! For correct work of script all images will be renamed!!

To avoid renaming if your tests are already have proper name format (like Picture_name_1.png with underscore and number in order), please comment lines 77-87 of makevids.py
