• There is a code that I want to make and improve with this code [closed]

  30 novembre 2023, par kenan bahadir

  crop_command = f'ffmpeg -i "input_file" -filter_complex "crop=1080:1080:420:0,scale=1920:1920:flags=lanczos" -acodec aac -strict experimental "temp_output_file"'
os.system(crop_command)

  


  My question is as follows : I want to upload a short video to YouTube. I have the code below, but it does not work as I want.
crop_command = f'ffmpeg -i "input_file" -filter_complex "crop=1080:1080:420:0,scale=1920:1920:flags=lanczos" -acodec aac -strict experimental "temp_output_file"'

• ffmpeg concat skips frames near end of each subclip

  3 janvier 2024, par calvinusesyourcode

  So I have some video files to concat but in the resulting video the last few frames of each subclip are buggy. Imagine in the last 5 frames the first 3 frames are skipped and so at the end of each clip it seems to jitter.

  


  It should be virtually impossible for my input videos to have any differences between them, as they were all recorded on the same iPhone and all converted with the same command :

  


  command = [
            'ffmpeg', '-y',
            '-i', input_path,
            '-vf', 'scale=1080:1920',
            '-r', '30',
            '-c:v', 'libx264',
            output_path
        ]
subprocess.run(command, check=True)


  


  I have tried re-encoding instead of merely copying and adding -r 30 but that doesn't seem to work.

  


  subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-c", "copy", output_path])


  


      subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-r", "30", "-c:v", "libx264", "-c:a", "aac", output_path], check=True)


  


  Somewhere someone said to open in VLC and do a frame-by-frame, reporting that "the frames are actually there, just not visually when watching normally". In my case the frame-by-frame reveals the frames are indeed being skipped.

  


  Full console output :

  UPDATE : I am thinking that the way I am converting my files from .mov to .mp4 is the problem. Please suggest the best way to convert from iPhone 4k 60fps .mov files to nice 1080p 30fps .mp4 files. I know I could just use handbrake but I am trying to be a man here xD. Perhaps handbrake has a View ffmpeg code for conversion.

  


  UPDATE 2 : re-encoding the videos before concat with -c:v libx264 fixes the problem... which seems weird because that is how they were originally encoded...

• FFMPEG = I tried resizing a video, but got different resolution than I wanted [closed]

  10 janvier 2024, par wakanasakai

  I downloaded a video that had some black bars (left & right), so I used the following command in FFmpeg to make various changes to it. I tested it on a 10 second clip to see what the result would look like.

  


  -ss 00:04:44 -to 00:04:54 -vf "crop=1870:20:20:0","scale=640x480:flags=lanczos","eq=gamma=1.5:saturation=1.3:contrast=1.2"

  


  The original video is an mp4, with a resolution of 1920 x 1080. Besides trying to crop it & adjust the gamma, saturation, & contrast, I also tried to resize it to 640 x 480. Instead, it's resulting resolution is 44880 x 480 ! I have a link to it for anybody who wants to examine it directly. (It's only 487 kb.)
text

  


  I've tried using FFmpeg before, & it never did anything so insane. (It cropped it, & adjusted the gamma a saturation (I didn't test the contrast until THIS time), but it did not resize it at all.)

  


  Here is FFmpeg's log file for it. Guesses as to the cause of the insane result, & advice on how to achieve the DESIRED result (in 1 pass, if possible) are requested.
