  • trimming video using ffmpeg corrupts output video stream

    6 décembre 2022, par I Z

    I am using ffmpeg to cut up a long video into sections. Using this command :

    


    ffmpeg -i "long.mp4" -ss 00:38:25 -to 01:01:11 -c copy "section.mp4" 


    


    I extracted a couple of different consecutive sections and they are fine. But then I cut out another one and its video stream is bad : just a few static frames are shown. Removing -c copy did not help. What am I doing wrong ? TIA

    


  • How to edit video (cut some scenes) without increasing the video's size

    18 février 2016, par 123iamking

    [Introduction]

    I have a video : Input.mp4 - length : 29 min 6 sec - size : 120 MB

    I use Microsoft Movie Maker 2012 (Movie Maker is included in the Windows Essentials 2012 program suite), to cut some boring scenes and keep the cool scenes and I get the video : Output.mp4 - length : 15 min 22 sec - size : 155 MB.

    And it’s take a long time to create the Output.mp4 and the size is ridiculously increased. I can’t use this kind of software anymore, I need to create a new software to serve my purpose.

    [Question]

    Is there anyway with C# .Net to simply cut and merge video without increasing the video’s size and have to be fast ?

    [What I have tried]

    I intend to use ffmpeg to cut the clip and merge the clip and I found something about cut video here , but the console said something about "Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future." - should I still use this ?

    Should I use ffmpeg or there’s better way to do this.

  • Extract first frame of multi video streams video

    15 avril 2020, par Radu

    I am curious about how to use FFmpeg in order to extract the first frame of the first video stream from a multi-video stream file. 
What I have so far is :

    



    ffmpeg -i {mediaFile} -ss 0 -map 0:v -vframes 1 -f image2 firstFrame.jpeg.

    



    I am not sure about the -map part. How can be certain that I work on the first video stream ? Is there a way to first filter streams by codec type, then select the first and then extract the frame ?

    



    Thanks.
