Video editor jupyter notebook

ODS video editor

Video editor jupyter notebook

Feature Concat audio and video parts

• cut (start, end) part of audio and video files
• merge video and audio file with the same length
• concat video files into common file

Feature Concat video and images frames

• cut (start, end) part of video files
• create video sample from static image with fixed duration
• concat ordered samples to common video

Structure

• notebooks/ods_video_converter.ipynb
• data
• • init *.mp4 files with audio
• • input
• • • audio *.mp3 files
• • • img *.jpeg files
• • • video *.mp4 files without audio
• • output *.mp4 result files with video and audio

Feature Inner DSL for video preparing pipeline

Set file aliasing

params = {
    'ww': 'data/init_hb/ww trailer 2 season.mp4',
    'ww_a': 'data/init_hb/ww music.mp4',
    'wh': 'data/init_hb/wh trailer.mp4',
    'wch': 'data/init_hb/wtch wild.mp4',
    'hb_i': 'data/init_hb/hb eu.png',
    'hb': 'data/init_hb/hb.mp4',
}

Describe pipeline, using syntax

• obj.a - get audio
• obj.v - get video
• obj.i - get image
• * merge into one clip different sources (video, audio, image)
• + concat by timeline video clips
• obj[10: 13] numpy like slice by time in seconds (including right border) Example

query = '''
        ww[43: 50].v * ww_a[75: 82].a +
        wh[158: 173].v * wch[15: 30].a +
        hb[3: 21].v * hb[3: 21].a * hb_i[0:18].i + hb_i[0:10].i
'''

Create MovDSL pipeline from movie_dsl.py, run query and save result file

dsl = MovDSL(params) \
    .query(query) \
    .save('data/output/dsl_example.mp4')
