A simple python helper to compress video.
Please install ffmpeg bin then install video_compressor
pip install video_compressor
# import VideoCompressor
from video_compressor import VideoCompressor, VideoInfo
# add your options
VideoCompressor(input='./example.mp4')
.mute(True)
.crop((0, 0), (100, 100))
.scale(640, -1)
.bitrate('1M')
.fps(24)
.codec_presect('h264WebVBR')
.quality('low')
.export('./export.mp4') # then export !
# read video metrics
info = VideoInfo('./export.mp4')
w, h = info.getResolution()
ismute = info.volumedetect()
video_bitrate = info.getVideoBitrate()
audio_bitrate = info.getAudioBitrate()
duration = info.getDurationInMilliseconds()
size = info.getSize()
fps = info.getFramePerSeconds()| option | value | description |
|---|---|---|
| mute | boolean |
Mute the video |
| scale | width, height |
Scale video to given width and height. If width = -1 or height = -1 scale video keeping ration. |
| crop | (origin_x, origin_y), (width, height) |
Crop the video from origin point (origin_x, orign_y) with given size (width, height) |
| bitrate | string like 1000000,1000k or 1M |
The average bit/seconds |
| fps | integer |
Number of frame per seconds |
| codec_presect | string 'h264WebVBR' |
Specify a codec preset used to encode video |
| quality | string 'low' or 'max' |
Specify a video quality |
For responsive video, you would export your video to different resolutions.
