MP4 and other types of video files, how to separate the picture and sound, to facilitate our post-editing or audio extraction needs? When processing video materials every day, we often need to obtain the background music or recording in the video separately, and only reserve the pure pictures for secondary creation. If one video is separated manually, not only the process takes a long time, but also the efficiency is extremely low when facing a large number of video files, and problems such as out-of-sync sound and picture, incompatible formats, etc. are easy to occur, then is there a stable and convenient way, can batch separate pictures and sounds in video formats such as MP4 and MOV, so that both files can be saved independently?
Here we will introduce a practical small tool for you, which can process multiple video files at one time, accurately split the image and audio, and can still completely retain the image quality and sound quality of the original video after splitting, while ensuring the consistent duration of the audio and video, providing great convenience for subsequent editing and use.
Why separate MP4 video image and audio?
Separateprocessing
the picture and sound in the video are bound together. If you want to modify them, you must move together. After separation, we can add filters to the picture separately to do special effects. At the same time, we can reduce the noise and adjust the volume of the sound separately. Both sides can change each other without affecting each other. It is much more flexible than directly on the original video.
Replace the video audio track
sometimes the live video is recorded because the environment is too noisy, or it is replaced by other background music. After the audio and video are separated, we can directly delete the original sound, replace it with a re-recorded dubbing or narration, and re-synthesize it back.
Extract sound and picture material
if we want to edit a video, we need to extract pictures from several videos, then extract audio from other places, and separate the pictures and sounds of each video. The pictures belong to the pictures and the sounds belong to the sounds, so we can combine freely like building blocks and have more creative space.
