Reframe is still in development and we know it needs a lot of improvements, So communities contributions are really appreciated🙇.

Features

• Frame Extraction: Extracts frames from video files.
• Convert Images: Convert images between multiple formats such as PNG, JPG/JPEG, WEBP, HEIF/HEIC.
• Resize Images: Resize images to desired size/ratio or use the multiplier to just upscale the size of the image.
• Background Remover: Remove background from an image and optionally replace it with a specified color.
• Bulk Support: Convert/Resize images in bulk by just passing the input_path/dir rather than passing them one by one.
• GIF Creation: An additional feature to create Animated GIFs just by stacking up multiple frames(images).
• Cross-Platform: Works on Linux, macOS, and Windows.

---

Requirements

• Python: 3.7 or higher.
• Dependencies:
  • Check out requirements.txt

Installation

Install via pip(Recommended):

By far the easiest way to install and use reframe-cli

pip install reframe-cli

Install from the source(github repo)

1. Clone the repository

git clone https://github.com/ForgeL4bs/ReFrame
cd ReFrame

2. Create a virtual environment(recommended)

python3 -m venv .venv
source .venv/bin/activate  # On Linux/macOS
.venv\Scripts\activate  # On Windows

3. Install the package in editable mode

pip install -e .

Arguments

In General(Required for all the features)

• -input: Input path to any directory or file from where you want to access the files
• -output: Output path to save the output

Frame Extraction(Optionals)

• -f: To specify the output format(Default = png)
• -fps: To specify the frames_per_second to extract, if not specified then all the frames will be extracted
• -start:The time (in seconds) from where you want to start the extraction
• -end: The time (in seconds) till where you want to extract

Image Conversion(Required)

• -f: sets the output format (e.g., 'png', 'jpg', 'jpeg', 'webp', 'heic')

Resize Image(Required)

• -wh: The width of the resized image
• -ht: The height of the resized image
• -ratio:The desired aspect ratio (e.g., 1:1, 3:4).
• Note: If you use -wh and -ht then you don't need to specify -ratio and vise versa, since both are for specifying dimension only(just use any one between) and yeah it goes same for -multi multiplier, cause it just multiplies your height width by the number you have specified, or you can say upscaled dimensions by -multi.

Resize Image(Optionals)

• -f: Is to specify format of the output image [choices are: png, jpg], if you need any other format, you can just convert it using the convert feature.
• -fp: The focal point for resizing ('left', 'right', 'top', 'bottom', 'center', 'auto'). Defaults to 'auto', which behaves like 'center'.
• -multi: The resizing multiplier (e.g., 2 for 2x). Overrides width, height, and ratio.

Background Remover(Optionals)

• -color: RGB color to replace the background. If None, the background will be transparent.

GIF Creation(Optional)

• -d: sets the duration of each frame in the GIF in milliseconds (default: 100ms)
• Note: In case of GIF -output you would need to specify the output path along with the .gif extension for the output file for ex: home/gour4v/output/test.gif

Usage

ReFrame-CLI provides three main functionalities: frame extraction, image conversion, and GIF creation. Use the reframe command to access these features.

• Frame Extraction

(Extract frames from a video file)

reframe extractf -input <video_path> -output <output_dir> [-f <format>] [-fps <frames_per_second>] [-start <start_time>] [-end <end_time>]

• Convert image format

(Convert images between multiple formats)

reframe convert -input <input_path> -output <output_dir> -f <format>

• Resize Image

reframe resize -input <input_path> -output <output_dir> [-wh <width>] [-ht <height>] [-ratio <aspect_ratio>] [-multi <multiplier>] [-f <format>] [-fp <focal_point>]

• Background Remover

reframe bgremove -input <input_path> -output <output_dir> -color 255,255,255(for white)

• GIF Creation

(Create animated gifs from images)

reframe gifc -input <input_dir> -output <output_path> [-d <duration>]

Examples

1. Frame Extraction

• Extract all frames from test.mp4 to the output_frames directory as PNGs:

reframe extractf -input test.mp4 -output output_frames

• Extract frames from video.mkv to the frames directory as JPGs at 10 frames per second:

reframe extractf -input video.mkv -output frames -f jpg -fps 10

• Extract frames within a time range:

reframe extractf -input video.mp4 -output output_frames -start 10 -end 25

2. Image Conversion

• Convert all images in input_images to PNG format and save them in converted_images:

reframe convert -input input_images -output converted_images -f png

• Convert a single HEIC image to JPG:

reframe convert -input image.heic -output converted_images -f jpg

3. Resize Images

• Resize all images in the input_images directory to 800x600 and save them in the resized_images directory:

reframe resize -input input_images -output resized_images -wh 800 -ht 600

• Resize all images in the input_images directory to a 3:4 aspect ratio along with focal_point left and save them in the resized_images directory:

reframe resize -input input_images -output resized_images -ratio 3:4 -fp left

4. Background Remover

• Remove Background for a Directory

reframe bgremove -input ./images -output ./bg_removed

• Remove Background and Replace with a slight reddish color

reframe bgremove -input ./images -output ./bg_removed -color 199,74,74

5. GIF Creation

• Create a GIF from images in the frames directory:

reframe gifc -input frames -output animation.gif

• Create a GIF with a custom frame duration (200ms per frame):

reframe gifc -input frames -output animation.gif -d 200
