Subtitle does not look right

Occasionally the subtitle does not look right after ripping from DVD with output of 856x480. The subtitle is ripped with remux option. See sample attached with error one (.mp4 ripped by DVDFab latest version 10.0.6.2) and good one (DVD) played by VLC player. Thanks.

You are upscaling the DVD when encoding, the remuxed subs are not equally upscaled so they no longer match up. If you want to upscale DVDs (not recommended) try direct render instead of remux.

Right, but why it happens only on a few DVDs but not others? What's the different? Can it be resolved? Thanks.

To add a point - the mp4 is ripped into 856x480 which is same resolution as VLC player plays on the screen as screenshot1. Thanks.

Hi,

We tried some DVDs and no problem, but they are all English subtitles.

Would you please upload one chapter of the DVD to us to check the problem? You can upload it to google drive or drop box.
