NVEnc-JPG2MP4

Multithreaded nvenc jpg to mp4 converter.

How to use:

1. Download the file and save it in the folder with the timelapse images for conversion.
2. The image files should be named 0001.jpg, 0002.jpg, 0003.jpg, and so on.
3. Open and edit the file convert_jpg_to_mp4.sh:

input_dir="."             # this is the input directory with JPG files, do not change this
output_file="output.mp4"  # this is the name of the output MP4 file :)
block_size=50             # this is the number of images in one processing block
max_instances=4           # this is the maximum number of concurrent ffmpeg instances,
video_bitrate="50M"       # this is the video bitrate

Note: Maximum number of concurrent ffmpeg instances, depending on your GPU's memory. For example, my GTX 1050 has 4GB of RAM, and max_instances is 5 for me. Above this value, I run out of memory, and the conversion is not performed correctly. If you see a lot of red text, reduce this value.

4. Save the file and give it executable permissions.
5. Open a terminal in the timelapse images folder and run the file:

./convert_jpg_to_mp4.sh
