What Causes the Large File Size of the Ripped DVD/Blu-ray File

Before we get started, one thing we need to make clear: what makes a DVD/Blu-ray file larger or smaller? Actually, there are many factors which can affect video file size while five variables that count for a lot in deciding the video file size. They are resolution, frame rate, time length, format and encoding. DVD/Blu-ray file size can be adjusted by changing these parameters. And you need to know that the video quality will be affected by changing them.

For the concept of reducing video file size has many technical variables associated with it, so we directly list the takeaway you can reduce the video file size:

  • Large resolution will increase file size, so choose a proper resolution for your video. Exporting at 720p will be a good plan to balance quality and file size.

  • The higher frame rate will cause larger video file size.

  • The longer the time length, the bigger the file size.

  • Format also affects video file size. We recommend you to choose MP4 of H.264 which preserve the best quality but smallest file size. For video formats, AVI formats will generate 10 times file size than WMV and 15 times than MP4 (the same video file). What's more, MP4 is the most compatible format.

Now that we know the gist of deciding the video file size, move on to get a helpful tool which makes work easier.
