Dynamic Frames to Video

• Basic frame to video script with ability to configure fps.
• Converts a series of image frames into video files. It outputs two video formats: H.264 (.mp4) and ProRes (.mov). The user can specify either the desired frame rate (frames per second) or the total duration (in seconds) for the resulting video.

Notes

• It shouldn't matter how your image sequences is named. Eg. 0000001.png, frame_0002.png, etc AND it does not matter if your file does not start at 0 or 1. eg. 00053.png is the first frame.
  
• This script also has the ability to compile your frames into a specifc duration video. Ie. If there are 1200 frames, and you input 3 seconds on launch - it will compile all 1200 frames into the 3 second video file.
  
• This script should help automate the process of converting a sequence of image frames into video files with user-defined frame rate or duration, making it a useful tool for various video processing tasks.

Prerequisites

• ffmpeg-python: Install the ffmpeg-python library:

  pip install ffmpeg-python
  

Running the Script

1. Prepare Your Frames Directory: Ensure you have a directory containing your image frames. The frames should follow a sequential naming convention like frame_0001.png, frame_0002.png, or 00000007.png, 00000008.png, etc.

2. Open your terminal, type python3 (include space) and drag your frames_to_video.py into the terminal which will paste the path name, then paste the pathname of where your sequentional PNG sequence is location

python3 /path/to/file/frames_to_video.py <path_to_frames_directory>

For example:

python3 /Users/Kynan/Scripts/frames_to_video.py /Users/Kynan/output_frames

What the Script Does

1. Validates Input Directory: Checks if the specified frames directory exists.
2. Determines Frame Pattern: Identifies the naming pattern of the image frames, the starting frame number, and the total number of frames.
3. Prompts for User Input: Asks the user to enter either the desired frame rate (e.g., 30 for 30 fps) or the total duration (e.g., 5s for 5 seconds).
4. Calculates Frame Rate if Duration is Given: If a duration is provided, it calculates the frame rate required to fit all frames into the specified duration.
5. Creates Output Directory: Creates a subdirectory named video inside the frames directory to store the resulting video files.
6. Generates Videos: Uses ffmpeg to create two video files:
7. H.264 encoded video (.mp4)
8. ProRes encoded video (.mov)
