Question

mp4をGIF書き出しすると速さが変わってしまう

After Effectsで24fpsで書き出したmp4をPhotoshopに読み込んで、「タイムラインのフレームレート」を24fpsにして、書き出し→web用に書き出し→GIF書き出しすると、速さが遅くなってしまいました。

GIF書き出しの設定画面で、画像サイズ(px)を半分くらいにすると元の速さに近づきました。

 

質問1:速さも画像サイズも維持したままGIF書き出しする方法はありませんか?

質問2:画像サイズを変更して調整するしかないようであれば、元の速さに近づけるためにはどのような調整が必要でしょうか?

 

よろしくお願いいたします。

    Hey, @ふくろうさん. Welcome to the Photoshop Community. I'll help you figure this out.

    What are the pixel dimensions of the GIF you're trying to export? How many total frames does the animation have?

    Where are you viewing the exported GIF, because different viewers handle GIF timing very differently?


    Try changing the delay between each frame in Photoshop to below 0.04 seconds, because the GIF format uses centisecond (1/100s) frame delays, so 24 fps comes to around 0.04s. You can do this in the Timeline panel by selecting Window > Timeline.


    Let me know how it goes.
    Thanks!

    Thank you for your help!

    I spoke with  ​@ふくろうさん , and it turns out they accidentally posted here in the global community. Since they are a Japanese speaker, we have requested to have this thread moved to the Japanese community forum. Thank you for your understanding!
