Why use Cutlia for this
The right shape
DVDs store 720 pixels across whatever the shape; the MP4 gets the real 16:9 or 4:3 frame.
Interlacing removed
DVD video is usually interlaced; it's deinterlaced so motion looks clean on computers and phones.
Dolby Digital to AAC
AC-3 and MP2 sound becomes stereo AAC, in sync with the picture.
Frequently asked questions
Which VOB file should I convert?
A DVD splits each title into VOB files of up to 1 GB (VTS_01_1.VOB, VTS_01_2.VOB…); VIDEO_TS.VOB is usually just the menu. Convert them one by one — or open them all in Merge Videos to join them into one MP4.
Does it work with movie DVDs I bought?
No. Commercial DVDs are copy-protected, and their VOB files can't be converted. Your own recordings and home-made DVDs work.
Is my video uploaded to a server?
No. Cutlia processes your video directly in your browser using WebAssembly and your device's hardware. The file never leaves your computer or phone, so it stays completely private.
