  • GPU produces laggy videos with ffmpeg [closed]

    10 août 2023, par Salah M. Wahsh

    I wrote a Powershell script to batch edited many videos. but the gpu renders the videos very laggy.

    


    so I'm trying to batch trim and downsize multiple videos using ffmpeg, it works perfectly when it utilizes the CPU. The problem is the CPU is slow when rendering the videos. So, after I utilized the GPU, the rendering time went down significantly which is great, but all the videos are very laggy for some reason. Anyone faced this issue before ?
My GPU is GTX 1050 3gb, I know it's considered a lower end GPU, but it's weird that it renders all the videos very fast so I recon the GPU don't struggle that much.

    


    this is the powershell script I'm using

    


    `New-Item -Path 'EDITED' -ItemType Directory

foreach ($file in Get-ChildItem -Filter *.mp4) {
    ffmpeg -hwaccel cuvid -c:v h264_cuvid -ss 00:00:00 -i $file.FullName -t 00:00:11 -c:v h264_nvenc -c:a copy -vcodec h264_nvenc -qp 23 ("EDITED/" + $file.Name)
}`


    


  • How to concatenate two videos and crop only one of them by using ffmpeg

    12 septembre 2013, par Tetsu

    I want to concatenate two videos.
    First video size is 720x420, and I want to crop 8px each side.
    Second Video size is 704x420, and I don't need to crop.

    And I want to resize the video 640x360 with encoding.

    How can I do it ? If both videos should be cropped, I can easily concatenate the videos like this.

    ffmpeg -i input1.avi -i input2.avi -filter_complex "concat=n=2:v=1:a=0, crop=704:420:8:0" -s 640x360 -vb 900k -an video.mp4

    How can I crop only one of the two videos ?
