  • how to trim video in h264 format using ffmpeg while preserving quality ?

    16 décembre 2020, par prisonmike11

    I'm new to ffmpeg,

    


    I'm trimming a small clip from a bluray H264 video by providing start and end duration.

    


    I tried :

    


    ffmpeg -ss 00:01:00 -i input.mp4 -to 00:02:00 -c copy output.mp4


    


    but this results in stuttering issues in start of the video. The audio and video also don't match.

    


    I tried using -c libx264 but this is taking too long and the output video has much lower bit rate.

    


    My goal is to trim as fast as possible while preserving quality. I don't care about the frame accuracy of the trim. I plan on uploading the output to youtube.

    


    what flags should I use ?

  • ffmpeg generated video with silent audio has different stream lengths

    18 septembre 2015, par JennHarper

    I am trying to generate a video clip of a single image and add a silent audio track for concatenating with other video files.
    I can successfully create the mp4 video with the desired image and audio track BUT, according to mediaInfo, the length of the video stream and the length of the audio stream are different. They are off by up to 60 ms. As I plan to concatenate several of these image clips and other video clips, I don’t want the error to accumulate. Any thoughts or suggestions for maintaining perfect video/audio sync ?

    Here are the ffmpeg commands that I am using :

    C :\FFmpeg\bin\ffmpeg.exe -loop 1 -i myImage.jpg -codec:v libx264 -t 7 -profile:v high -preset slow -r 25 -b:v 500k -maxrate 500k -vf scale=1280:720 -y videoStreamOnly.mp4

    C :\FFmpeg\bin\ffmpeg.exe -f lavfi -i anullsrc=r=48000 -i videoStreamOnly.mp4 -shortest -c:v copy -c:a aac -strict experimental -y videoWithSilentAudioStream.mp4
