QUICK ANSWER
Is it possible to convert BUP to MP4?
No - not a direct conversion.

A .bup holds no media content - it is a byte-for-byte copy of a DVD's .ifo navigation file. To get an MP4, point HandBrake at the full VIDEO_TS folder; the video and audio are in the .vob files.

Why convert BUP to MP4?

The 1996 DVD-Video specification divides disc content into three file types: .vob files hold video and audio streams, .ifo files hold navigation data, and .bup files are exact copies of the .ifo files placed in a different physical disc area for scratch protection. An .mp4 container requires encoded video and audio streams, none of which exist inside a .bup.

How to convert BUP to MP4

HandBrake FREE

Open the VIDEO_TS folder in HandBrake, select a title, choose MP4 as output, and encode - HandBrake reads .ifo/.bup for chapter structure and encodes video and audio from the .vob files.

MakeMKV FREE

Open the VIDEO_TS folder in MakeMKV for a lossless MKV copy of the disc; use HandBrake afterward to re-encode to MP4 if a compressed file is needed.

Quality & what to watch

  • Any site claiming to convert .bup to .mp4 is either mislabeling a file-rename tool or is not legitimate - a .bup holds no video data.
  • If a .ifo is missing or corrupted, copy the matching .bup and rename the copy to .ifo before running HandBrake.
  • VLC can play the VIDEO_TS folder directly (Media > Open Folder) without any conversion.

Frequently asked questions

Is there any software that converts BUP to MP4?
No - the conversion cannot exist because a .bup holds no video data; any site claiming otherwise is either mislabeling a rename tool or is not legitimate.
Why do I have BUP files in my DVD backup folder?
The DVD-Video specification requires each .ifo file to have a .bup counterpart in a separate physical disc area; when you copy a DVD to disk, the .bup files come along as part of the required VIDEO_TS structure.
How do I play my DVD backup?
Open the entire VIDEO_TS folder in VLC (Media > Open Folder) - do not try to open the .bup file directly.
