I am using ffmpeg-python and I am trying to make a code that gets all the clips from a folder, converts all of them to the same format then merge all of them with their audio to one final video file.
Here is how the python script looks like
import os
import ffmpeg
dir = "./clips/"
# Reshape video
for f in os.listdir(dir):
(
ffmpeg
.input(os.path.join(dir, f))
.filter("scale", size="hd1080", force_original_aspect_ratio="increase")
.filter('fps', fps=60, round='up')
.output(str(os.path.join(dir, f))[:-4] + "_reshaped.mp4")
.run()
)
# Select reshaped video
files = []
for f in os.listdir(dir):
if "_reshaped.mp4" in str(os.path.join(dir, f)):
files.append(ffmpeg.input(str(os.path.join(dir, f))))
# eparate video and audio, then flat the array
video_and_audios_files = [item for sublist in map(lambda f: [f.video, f.audio], files) for item in sublist]
# concat all
joined = (
ffmpeg
.concat(*video_and_audios_files, v=1, a=1)
.node
)
# merge video and audio
(
ffmpeg
.output(joined[0], joined[1], "./out.mp4")
.run()
)
Now here is my output, this is the output of the part of the code that merges every clip into one (aka the merge video and audio section of the code)
