Hi all,

I will make use of the new subtitle feature, and hardcode subtitles to an MKV file, since my telly doesn't support external or embedded subtitles for MKV files.

Thus, need to transcode the file.

But how do i choose the transcoding quality (or keep the quality off the original file "untouched" in the proces ) ? Because the transcoded file is in a real bad quality, totally unwatchable..

Tried "Force full Transcode of all channels (no remuxing)" but still very bad quality.

Would appreciate someone pointing me in the right direction.

TIA :)

The problem may be the wrong device profile assigned to your device. Please tell us the device you are streaming to (incl. model number) and the device profile that is assigned to your device in the Media Devices dialog in Mezzmo. And, also post the FFmpeg information on the video file that you are streaming. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.

Hi Paul,

My tv is a Panasonic Viera VT20, and i am using the device profile "Panasonic Viera (2011 models)".

Furthermore, under "Device settings" for this profile, under the tab "Performance" i have chosen "Maximum video size" which corresponds to 1920 x 1080, and "Video bitrate" is set to "Best quality".

Is there a description regarding the new subtitle hardcoding feature by the way, so i could read up on the function ? Unaware if you have to pre-transcode a file for making use of the feauture, or if you can also make use of the feauture when transcoding "on the fly".
