  • My filters seem to be applied in wrong order

    4 septembre 2020, par Jao

    I'm using ffmpeg to join frames into a video with some parameters.
Here is a sample of the commands I run :

    


    


    "ffmpeg -y -r 24 -f image2 -i "C :\Users\Pictures\me\frame%04d.bmp" -filter_complex "[0:v]select=between(n,0,76)[selected] ;[selected]crop=in_w:in_h-60-60:0:60[cropped] ;[cropped]scale=w=2ceil(2048.0/20.5):h=2ceil(858.0 /20.5) " -c:v libx264 -q:v 1 -b:v 2M "C :\Users\me\Video\output.mp4""

    


    


    When I run this command I have calculated the size of my cropping on the frames to remove black rectangles at the top and bottom of the frame (I tried using cropdetect but it doesn't fit my usecase so I'm using another soft).So my first that was that ffmpeg would crop on the input stream so it would only crop my black rectangles. But when I change my scale it crops a part of the image.

    


    So my understanding is that ffmpeg crops after scaling (maybe I'm wrong) and if I get the crop parameters on the input images it is sure the they will be wrong if I apply them on the scaled video.

    


    I tried using " ;" and "," to separate my filters. I tried naming and not naming my streams between filters. Nothing seems to solve my issue.

    


    What could I do to fix that or am I understanding the issue incorrectely ?
Thanks in advance

    


  • Convert video using ffmpeg for watermark creation with multiple text

    19 septembre 2016, par Iura Gaitur

    I want to convert a video using FFMPEG and place a watermark with multiple texts on it. Combining the commands for placing a text and a watermark is :

    ffmpeg -i input_1.mp4 -i watermark_small.png -filter_complex "[0]overlay=10:10; [1]drawtext=enable='between(t,0,12)':fontfile=font.ttf:text='Some text' : fontcolor=black: fontsize=18: box=1: boxcolor=yellow@0.5:boxborderw=5: x=(w-text_w)/1.15:y=30, drawtext=enable='between(t,14,22)':fontfile=font.ttf:text='Next text' : fontcolor=black: fontsize=18: box=1: boxcolor=yellow@0.5:boxborderw=5: x=(w-text_w)/1.15:y=30" -codec:v libx264 -preset ultrafast output1.mp4

    Unfortunately this command puts the watermark and the first text but not the next text. I assume the problem is on -filter_complex setting. Unfortunately I don’t know how to set it in the right way in order to work. Could someone help me and say what needs to be changed in this command in order to convert it in the right way ?
