  • Concatenate Movies from Python List using MoviePy or FFmpeg

    24 September 2020, by Python_Learner_DK

    I have about 10,000 short videos that I am trying to make several longer videos from.

    



    I've created these videos using MoviePy, but keep getting memory errors when trying to concatenate them back together.

    



    In my code I have an outer loop going through each letter of the alphabet and getting the files that start with that letter.

    



    From the returned video clips I get the length and and strip off the last 3.5 seconds (outro_clip_duration) of the video, and then add it into a Python list clips.

    



    Where I'm stuck is I then want to take this list of trimmed videos and make one long long video from it.

    



    I have all the files, I just need to trim them, concatenate them, and then export them as one.

    



    I've tried many times with different MoviePy attempts and keep getting MemoryErrors so I gave up and took a swing at an ffmpeg solution seen here but it is not working out either.

    



    The latest version of the main part of my code is here:

    



    clips = []
outro_clip = mpy.VideoFileClip('Logo_Intro_w_Stinger_Large.mp4')
outro_clip_duration = outro_clip.duration
for def_image in vid_list_long:
    video_item = mpy.VideoFileClip('F:/sm_My_Video/sm_%s.mp4' % def_image)
    video_item_duration = video_item.duration
    clips.append(ffmpeg_extract_subclip(video_item,0,(video_item_duration - outro_clip_duration), targetname = def_image))

# #Append the outro_clip to the end 
clips.append(mpy.VideoFileClip('Logo_Intro_w_Stinger_Large.mp4',target_resolution = (h,w),audio=True))
slided_clips = [CompositeVideoClip([clip.fx( transfx.crossfadein, transition_seconds)]) for clip in clips]
#added 'method = compose' NEED TO TEST - supposedly removes the weird glitches.
c = concatenate_videoclips(slided_clips, method = 'compose')
c.write_videofile('F:/Extended_Play/%s_Extended_Play_vid.mp4' % letter,fps=23.98)

  • Linux Platform: Enlarge video screen size N times

    27 January 2012, by Susan Mayer

    I am looking for a application on Linux platforms (Ubuntu/CentOS etc) that can enlarge video size N times. N could be any number, like 1.5, 4 etc

    For example, if I have a video with screen size 100*200, I want to make it 1.5 times larger, that will be: 150*300. Of course, I will expect the video quality to drop but it doesnt matter.

    I am not sure whether ffmpeg has this function but a quick Google lands me nowhere. So I am here now.

    Thanks a lot!
