HFR-Resampler

HFR-Resampler is a tool to resample high framerate video into lower framerate video with customizable weighting.

Example

the example

yeah i know the difference between gaussian and pyramid is subtle, but it’ll become adjustable in the future

How to use

1. Download the latest release
2. Extract it
3. Copy the video into the same folder
4. Open your Command Line/Terminal on that directory, and then type resampler.exe -h to show the help, see more detailed explanation below.

Usage

You can use this program by running resampler.exe via terminal or cmd. Then, you can use the available arguments to customize the resampling process.

Required Arguments

• -i INPUT_NAME : Specify the name of the input video file with
  extension

• -o OUTPUT_NAME : Specify the name of the output video file with
  extension

Optional Arguments

• -h : Show help menu provided by the program

• --version : Show the version of the program

• -fps FPS : Specify the framerate of the output video

• -r BLEND_RANGE : Specify the Blend Range of the resampling process.
  It’s the number you get from resampled frame count divided by
  fps ratio of the input and output video. Normal resampling is 1.0, but you can use 1.5, 2.0, or more, to resample more frames.

• -m BLEND_MODE : Specify which blending mode to use. More details
  later below.

• -res WIDTHxHEIGHT : Specify the resolution of the output video. Use
  -res UNCHANGED for no rescaling. This is also applicable in the
  settings.json file.

• -fourcc FOURCC_CODE : Specify which video codec you want to use. Example : -fourcc MPEG

• -cvfix : Enable colorfix ffmpeg script to fix the weird colorspace of the input video writen by OpenCV video writer.

Blend Mode
Blend Mode can be specified using keywords below. (case-insensitive)

• EQUAL
• GAUSSIAN
• GAUSSIAN_SYM
• PYRAMID
• PYRAMID_SYM
• CUSTOM_FUNCTION
• CUSTOM_WEIGHT

Example : -m equal , -m custom_WeIghT

Output Filename Format
You should use video file format / video container that supports the codec you are using for the resampling process. For example, if you use FFV1 codec, you may want to use .mkv file format.

Example
resampler.exe -i input.mp4 -o input_resampled.mkv -fps 60 -m 6 -r 2.0 -res 1920x1080
Will use “input.mp4” as input, and will output “input_resampled.mkv” on 1920x1080 resolution on 60 FPS. Which used my own Weighting Preset as the Weighting Method, and resampled on 2.0 blend range.
