不同格式的視頻大小差異


0

我正在VSDC上進行視頻編輯,當我將其導出為mp4格式時,導出的內容比原始視頻大得多。我對視頻所做的只是從視頻中刪除聲音,然後將其替換為我用大膽清除後將其導出為wav格式的聲音。視頻的原始大小為34mb,而wav文件約為4mb,但導出量超過200mb。我使用軟件為youtube導出的選項將其導出,並將質量設置為1080p。我不明白髮生了什麼事。可能是我的原始視頻質量比1080低嗎?並且該軟件正在添加填充像素?這些是我應該查看的數字嗎?原始文件是mov。

當我導出到avi時,文件大小更合理,為31mb。甚至只向mkv出口41mb。

You first need to tell us which software you're using. I'm assuming it's the adobe media encoder? Handbrake? ffmpeg?

Nonetheless, the filesize is determined by your resolution, framerate and bitrate. Try exporting the video with VBR with 2 passes and set the bitrate to something between 3 and 6 - that should be enough for a 1920x1080 h264.
