"Chapter <#>" displayed on-screen throughout .mp4 videos

[Vernholio]

Hey all,

New to the forums, and was hoping I could get a little assistance. I've taken several DVDs and decrypted them using MakeMKV, and I've packaged them as .mp4's using Handbrake. I've set up Mezzmo as my DLNA server on my Windows 7 PC, using an external 3 TB WD USB hard disk. In trying to stream these mp4's to a Sony Blu Ray player (BDP-S590), they appear for playback, no problem (FINALLY... after screwing with a few other DLNA server apps). My problem is, the .mp4s have "Chapter One" across the bottom of the screen (kind of, subtitle style). The thing is, this doesn't appear when I playback the videos directly on my computer, and, when I got playback to intermittently work via another DLNA server, I didn't see this either. I'm hoping that there is a setting I can apply to drop this. I found in Handbrake, that I can "turn off" Chapter Titles, I'm just not sure if this will work (and I know, this isn't a Handbrake forum). Regardless, I just really don't want to waste the time re-packaging the content as .mp4.

Any ideas?

Thanks in advance,

- Vern

Hi Vern,

Let's see if this "Chapter" information is stored as text metadata inside your MP4s. Right-click on an MP4 in Mezzmo and click 'Get FFmpeg Information'. Have a look at the FFmpeg information (and/or post it here and we'll take a look as well) to see if you can see the chapter information you are seeing on your device.

Yep... It looks like it does:

Is there any way to update the metadata to remove the "title" lines?

Thanks!

[Paul]

The only way to remove this text metadata is to re-encode them using (in your case) Handbrake. Try re-encoding one MP4 and then adding it into Mezzmo and getting FFmpeg information again to make sure it has been removed.

Another possibility: Check if your Sony Blu-ray player has an option to turn off these chapter display marks. Press Settings or Options button on your Sony remote control and browse the various settings to see if you can turn them off.

[Vernholio]

I really appreciate all of your help, and the quick responses, as well! Unfortunately, there is no setting I can find on the Blu-Ray player that disables the chapter display marks. I don't know which is more odd in my opinion... That Handbrake throws them in there by default with the "Normal" preset, or that Sony thought it was a good idea to force display of those titles! (BTW, I just got Mezzmo up-and-running with my Roku 3 player on a separate TV, and sure enough... it doesn't display the chapter display marks, either!)

Guess I'm off to re-encode those MKV files (fortunately, there are only 5 of them!)

Thanks again!

[Paul]

OK - let us know if you come across any other problems and we'll try to help.

Maybe just running them through MKV Merge & removing all but the video & audio streams , plus any global items , might do the trick. Less than 30seconds per video probably.

MKV Merge is part of the MKVToolnix suite (free btw)

FWIW ... I have the same problem. I use HandBrake to convert the video. When I tried playing with Mezzmo it displays the chapter info. But when I played the same file with TVersity it does not display the info. Seems to be more Mezzmo related than the player. FYI.

[Peter]

Hi,
Handbrake may be encoding the chapter info as a subtitle stream, please try going to the properties of the file in Mezzmo and on the subtitles tab uncheck the box for the subtitle and this should prevent the chapter info appearing.
