• reverse Video : Moviepy Error, by using time.mirror

  22 août 2023, par stelidakis

  im desperately trying to reverse a movie with moviepy by using .time_mirror.

  


  from moviepy.editor import *
import moviepy.video.fx.all as vfx
# Load the video
video = VideoFileClip("/videos/uncut/videogames/other/001.mp4")


popreversed_video = video.fx(vfx.time_mirror)

# Save the reversed video
reversed_video.write_videofile("videos/cut/videogames/other/001_rev.mp4")

print("done")


  


  but im always getting this error :

  


  MoviePy error: failed to read the first frame of video file /videos/uncut/videogames/other/001.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance the version in the repos is deprecated. Please update to a recent version from the website.&#xA;  File "/Shorts Project/codefiles/video_play_and_rewinde_test_001.py", line 11, in <module>&#xA;    popreversed_video = video.fx(vfx.time_mirror)&#xA;OSError: MoviePy error: failed to read the first frame of video file /videos/uncut/videogames/other/001.mp4.

• ffmpeg : How to add an image to the end of a video, freeze framing the last frame and using a fade

  26 novembre 2019, par Jeremy Thomerson

  (I’ve looked at a number of other similar questions, but can’t find any with an answer that actually works)

  I often need to combine a short video clip with in image. Typically, the video clip is a short explanation of a concept, followed by an image that helps the user visualize the concept. Rarely do the frame sizes / resolution of the video and image match. Typically, I need every second of the video clip to display, so even though I would like a cross-fade between the video and image, I’d like to freeze-frame the final frame of the video, and then cross-fade between that frozen frame and the following image.

  I’d like both the video and image, despite the disparity in their resolutions, to "fit to frame", such that I get an output that’s either a) the size of the larger asset, or b) some fixed size (like 720p), and in either case, both the image and video are scaled to fit into those dimensions, while maintaining their original aspect ratio.

  For example, given the following two assets (video and image), how could I accomplish what’s described above ? (Note : these assets are just ones I found that are available for examples, and not the actual type of content I’d be using ; however, they do accurately represent the disparity in resolution and aspect ratio I’d often have between video and image file).

  • https://upload.wikimedia.org/wikipedia/commons/e/e8/World_blank_map_countries.PNG

  Bonus : At times, I’d like to :

  1. Reverse the order (image, and then video), or
  2. Have a video and then multiple images, one after the other, faded between each, or
  3. Video, fade to image, then more video

  Note : I’m running ffmpeg on Mac / OSX, installed via brew

  Thanks so much if you can help !

• How to permanently make ffmpeg recognizable from bin/bash in macOS

  10 avril 2022, par Anonymous

  I downloaded a zip for ffmpeg, because brew installation was not compatible with macOS High Sierra 10.13.6. After unzipping, the only file contained was ffmpeg, its icon is similar to the icon of the terminal. I want to get the terminal(which runs bin/bash $SHELL) to permanently recognise ffmpeg command.

  


  If I type :

  


  

  1. echo export PATH="/Users/imac/Documents/ffmpeg:$PATH" > ~/.bashrc

  


  2. source ~/.bashrc

  


  3. ffmpeg
then the command ffmpeg is recognized, so everything is ok.

  


  


  However if I exit the terminal and re-open it, or just restart the computer
ffmpeg gives as output -bash: ffmpeg: command not found. So I have to do every time steps 1 and 2 that were describe above.

  


  


  4. Output of cat .bashrc :
export PATH=/Users/imac/Documents/ffmpeg:/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

     


  


  5. Output of echo $PATH :
/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

     


  


  


  Note that in step 4 ffmpeg appears(in the location I have it stored) whereas in step 5 ffmpeg is absent. Also I have little knowledge of bash and terminal, so if you can, please be explanatory in answers and/or comments. Thank you very much !
