• Create video scroll image

  17 février 2019, par Dinh Quang Khang

  I am creating video scroll vertical image with ffmpeg.

  But video is very bad. Although I set frame rate is 200, it is jerky.

  My video in youtube

  -i "D:\FFMPEG\source.jpg" -i "D:\FFMPEG\logo.png" -i "D:\FFMPEG\audio.mp3" -f lavfi -i color=c=white:s=1280x720:d=41 -f lavfi -i color=c=white:s=1280x720 -loop 1 -filter_complex "[2:a]afifo[audio];[4:v][0:v]vstack=inputs=2[source];[3:v][source]overlay=shortest=1:y='-(t)*200'[source_video];[source_video][1:v]overlay=39:39[video]" -strict very -preset ultrafast -t 00:00:41 -vcodec libx264 -r 200/1 -map [video] -map [audio] "D:\FFMPEG\output.mp4"

• is there a faster way to extract various video clips from different sources and concatenate them, using moviepy ?

  27 août 2019, par user2627082

  So I’ve made a small script using moviepy to help me with my video editing process. It basically scans a bunch of subtitle files for specified words and the time duration when it occurs. With that it extracts that particular time duration from video files corresponding to the subtitle files. The extracted mp4 clips are all concatenated and written into one big composition.

  So it’s all running fine but it’s very slow. Can someone tell me it’s possible to make it faster. Am I doing something wrong ? Or is it normal for the process to be slow.
