  • Insert video into another video both of different formats in a time efficient way

    7 février 2017, par Sharath Huddar

    I have an assignment which requires that the code I write takes a large video(1 to 3 hrs) and a smaller video (10-60 seconds) and the smaller video is inserted at intervals of 30 minutes into the larger video. Note that the videos are not necessarily in the same format.

    I tried to encode the large and the small video to a common format (mp4) and then split the large video based on time (while encoding it to mp4) and then concat all the videos in a predefined sequence (also while encoding to mp4). All these operations were carried out using FFMPEG.

    Although this method worked, it too close to 20 hours to perform the whole operation on an Intel NUC (having an i5 processor and 8GB RAM)

    Is there a faster way to do this without compromising on quality ?

  • Is there any way to use ffmpeg to download the video url and sync the video and audio without encoding ?

    20 juin 2023, par Daniel Lee

    I downloaded a video URL with audio, but the duration of the video and the duration of the audio are different and I want to match them.

    


    I want to use the shortest option, but I can only do that by extracting the audio separately and taking two inputs, audio and video.

    


    Is there an easy way ?

  • How to replace the video track in a video file with a still image ?

    22 février 2021, par cornerstore

    I am trying to use ffmpeg to replace the video track in a video file with a still image. I tried some commands I got from other questions such as the one here

    


    ffmpeg -i x.png -i orig.mp4 final.mp4

    


    ffmpeg -r 1/5 -i x.png -r 30 -i orig.mp4 final.mp4

    


    But these didn't work. I'm not sure which of these arguments are required or not. The output should be accepted by YouTube as a valid video - I was able to simply remove the video track, but apparently they don't let you upload a video without a video track.
