  • Smart y coordinate to make vertical alignment for the text with typewriting effect

    31 août 2021, par Макс Шульдинер

    I'm doing animation for the typewriting effect. Here is my ffmpeg string :

    &#xA;

    -i ffmpeg_inputs/output-onlinegiftools.gif  -vf "[in]drawtext=fonts/RobotoMono-Regular.ttf:text=&#x27;h&#x27;:fontcolor=orange:fontsize=35:x=(w-text_w)/2-200&#x2B;0:y=h-th-400:enable=&#x27;between(t,0.00, 7.80)&#x27;, drawtext =fonts/RobotoMono-Regular.ttf:text = &#x27;i&#x27;:fontcolor=orange:fontsize=35:x=(w-text_w)/2-200&#x2B;25:y=h-th-400:enable=&#x27;between(t,0.80, 7.80)&#x27;, drawtext =fonts/RobotoMono-Regular.ttf:text = &#x27;g&#x27;:fontcolor=orange:fontsize=35:x=(w-text_w)/2-200&#x2B;75:y=h-th-400:enable=&#x27;between(t,1.60, 7.80)&#x27;, drawtext =fonts/RobotoMono-Regular.ttf:text = &#x27;u&#x27;:fontcolor=orange:fontsize=35:x=(w-text_w)/2-200&#x2B;100:y=h-th-400:enable=&#x27;between(t,2.40, 7.80)&#x27;, drawtext =fonts/RobotoMono-Regular.ttf:text = &#x27;y&#x27;:fontcolor=orange:fontsize=35:x=(w-text_w)/2-200&#x2B;125:y=h-th-400:enable=&#x27;between(t,3.20, 7.80)&#x27;, drawtext =fonts/RobotoMono-Regular.ttf:text = &#x27;s&#x27;:fontcolor=orange:fontsize=35:x=(w-text_w)/2-200&#x2B;150:y=h-th-400:enable=&#x27;between(t,4.00, 7.80)&#x27;[out]" ffmpeg_outputs/test2.gif -y &#xA;

    &#xA;

    Here is the results with different y values :

    &#xA;

    enter image description here

    &#xA;

    enter image description here

    &#xA;

    As i understand, to make smooth sentence, for some letters i need top vertical alignment, and for others i need bottom vertical alignment. How can i make this "smart alignment", or the only one method is to hardcode y values for different letters ?

  • Vertical video play does not sync with multiple stacked video

    5 novembre 2018, par Sabha

    I dont know if I have wrote the subject well and if that can be understood. Nevertheless, here is an explanation

    I have 7 videos of different dimensions where the width is same (1080). I wish to place them one below the other to get a full hd vertical video (1080x1920). I tried the -filter_complex vstack filter in ffmpeg and got all the videos aligned one below the other and I am getting a perfect 1080x1920 full hd vertical video but they dont sync with each other. Once the videos are in sync, I need to put an audio too which should also sync with the in-sync video that will be made.

    There is so much of complexity. Please advice how do I make them sync. Is there any software that can allow me to put 7 videos one below the other in a timeline ? (if not 7, atleast 3-4 videos). Please advice where and how to start.

    Is there any option in Adobe Premier or any other software ?

    Thanks

    EDIT : I am doing a very long procedure to combine all 7 videos vertically

    first i use

    ffmpeg -i video1.mp4 -i video2.mp4 -preset veryslow -filter_complex vstack video12.mp4

    and then

    ffmpeg -i video12.mp4 -i video3.mp4 -preset veryslow -filter_complex vstack video123.mp4

    so on and so forth

    Is there a better way to do it all in one command ?
