Why convert VOB to WEBM?
- A separate copy makes it easier to compare the old and new behavior.
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
- The output can be tested in the destination workflow before the original is archived.
Will quality change?
Re-encoding can soften fine detail and change the file size. Keep the original master if editing or archival quality matters. Review the file in the application where it will be used.
