Q: Is .bup a video file? How can I play BUP files? I am planning on adding a scene from the epic movie onto YouTube, but .ifo and .bup aren't working and every time I click YouTube with .vob, it doesn't take me to the additional detail page so I can't save or edit it!
We have introduced the importance of .ifo files in DVD video and the relation with .vob files. By contrast, many people think that the .bup file is inconsequential because the .bup file can neither play nor convert. So some users even want to get rid of .bup file. Actually, .bup file is short for backup, it also plays an important role in the DVD video because the .ifo file has the vital effect on the play of DVD. Therefore all .ifo files have their backup files, namely the .bup file with the same name.
Once an IFO file is damaged or can not be read due to scratches of DVD, DVD player will defer to the corresponding .BUP file to load your DVD. As the same as IFO files, BUP files are not media files, and can not be played either. However, a DVD won’t be recognized and play in DVD Player while lacking of either one. So the BUP to MP4 conversion mentioned in this article is based on the conversion of the entire DVD folder (Video_TS) that contains all BUP, IFO, and VOB files.
