My video input is mpeg2 video file as follows:

Video: MPEG2 Video 720x576 (4:3) 25fps [V: mpeg2 main, yuv420p, 720x576]
Audio: MPEG Audio 48000Hz stereo 224kbps [A: mp2, 48000 Hz, stereo, 224 kb/s]

Then I use:

ffmpeg.exe -i in.mpg -b:v 3000k -preset superfast out.mp4

To get MP4:

Video: MPEG4 Video (H264) 720x576 (4:3) 25fps 2967kbps [V: h264 high L3.0, yuv420p, 720x576, 2967 kb/s]
Audio: AAC 48000Hz stereo 128kbps [A: SoundHandler (aac lc, 48000 Hz, stereo, 128 kb/s)]

Everything is good, except I get something like this in motion scenes:

enter image description here

In the actual source, there is no such thing. In the source, there is no intermediate frames or ghosting - just "discrete" steps.

I tried other presets, as well as other codec like libxvid, but all produced the same result.

So, how should I fix it? Which parameters should I add or which settings to adjust?

  • Can you provide a short sample input file containing an action scene? You can create it using something like: ffmpeg -ss 600 -i input -c copy -t 5 output.mpg – llogan Dec 21 '15 at 19:06

    Try increasing bitrate. Though it is more common to encode with the crf option to get constant quality. – jiggunjer Dec 21 '15 at 23:44

Your input source in interlaced. Your best bet is to deinterlace with an ffmpeg filter such as -vf yadif=1. See yadif documentation for more info.

    Note that yadif=1 should only be used when there is effectively 1 field per frame, otherwise you'll end up with dup frames. If that's the case, using -vf yadif will be more efficient. – Ely Dec 22 '15 at 19:45
  • Ely, I think you are mistaken about yadif=1 . Yadif =1 will treat each field as a frame. . 2 Fields per frame will cause a doubling of the frame rate, thereby preserving the interlaced resolution, as temporal resolution. Most any other option for deinterlacing will cause a loss of resolution. – Tekno Geekz Nov 19 '19 at 8:04
