Video ffmpeg视频水印（输出视频大小过大）

我在大约2MB大小的视频上运行ffmpeg，在对它们进行水印处理后，我的视频文件的大小约为13-17MB。我做错什么了吗。请帮忙

我的代码是

ffmpeg -i "C:\flask\mobile_form\Videos\20191231140058_987654567.mp4" -i "C:\flask\mobile_form\resizeLogo.jpg" -filter_complex "[0:v][1:v]overlay=10:10,drawtext=text=Hello:fontsize=24:x=main_w-200:y=main_h-100,drawtext=text=World:fontsize=24:x=main_w-200:y=main_h-60" "C:\flask\mobile_form\waterMark\second.mp4"

这是我的完整日志，它没有给出任何错误，但我希望我的输出文件更小

这是我的代码的完整日志

我们可以使用encode对H264视频进行编码。 尝试添加：

-vcodec libx264

我们可以通过以下方式选择比特率：

-b 200K

---

（例如）

我尝试使用-vcodec libx264，但没有效果。使用-b 200k破坏了视频，显示了你命令中的完整日志。我已经编辑了我的问题并添加了完整日志。
