Introducing how to make a slideshow-like video by connecting "photos taken every day from the same place". Use the Python library MoviePy.
$ pip install moviepy
[Reference] A site that describes how to install MoviePy
If you just want to do what you want to do this time, just the pip install moviepy command should be fine
Prepare a still image to make a slide show
Under the `ʻinputdirectory, place still images (extensions .png, .jpg``, etc.) by indexing them in the order you want to connect them in the slide show.
The following is an example, but if you sort by file name in the Python source in ascending order and arrange them in the order you want to connect in the slide show, you do not have to follow the following naming rules.
input
├── IMG_0000.jpg
├── IMG_0001.jpg
├── IMG_0002.jpg
├── ...
python create_slideshow.py, you will get a moving image ```output.mp4`` with still images connected at 0.5 second intervals.create_slideshow.py
#!/usr/bin/env python3.6
# -*- coding: utf-8 -*-
import glob
from moviepy.editor import *
if __name__ == '__main__':
#The extension under the input directory is.Get jpg file name list all at once
file_list = glob.glob(r'input/*.jpg')
#Sort the file name list in ascending order
file_list.sort()
#Processing to store still image information that is the basis for creating a slide show
clips = []
for m in file_list:
clip = ImageClip(m).set_duration('00:00:00.50')
clip = clip.resize(newsize=(640,480))
clips.append(clip)
#Processing to create a moving image of a slide show
concat_clip = concatenate_videoclips(clips, method="compose")
concat_clip.write_videofile(r"output.mp4",
fps=24,
write_logfile=True,
)
clips = []
for m in file_list:
clip = ImageClip(m).set_duration('00:00:00.50')
clip = clip.resize(newsize=(640,480))
clips.append(clip)
ImageClip(m).set_duration('00:00:00.50')clip.resize(newsize=(640,480)) concat_clip = concatenate_videoclips(clips, method="compose")
concat_clip.write_videofile(r"output.mp4",
fps=24,
write_logfile=True,
)
method can select chain or compose. Looking at the document, it seems better to use compose if the size of the moving image before connecting is different. In this case, the size of the moving image is set to 640x480 in advance and it is the same size, so it has been confirmed that it works even if method = "chain". write_logfile = True, the log that creates the output file will be output with the name `ʻoutput.mp4.log`` as shown below, and you can see that ffmpeg is running behind the scenes.text:output.mp4.log
