Video Thumbnail Size on Samsung TV

[Gus]

First of all, i appreciate you're really busy at the moment, so no big hassle on this one...it's just i'm fed up with seeing poor scaled and blocky video thumbs/covers. I've tried dozens of diffent sizes and they all look blocky. The only resolution i can get to look half decent is 108x65. But i'm certain it should be more like 216x130 based on the actual image size on the 1920x1080 screen.

Anyway, is there a setting to customise the thumbnail size that is sent to the TV ? either in the GUI or in profile setting etc.
I know there is a function in Tools, Options but that wont go below 160 ?

I noticed in the samsungla profile there's a setting for JPEG thumb size (320x320) but i cant see a setting for Videos.

Again, no rush.

thanks

When you change the resolution in Options, you'll need to run Maintenance and update all information (this will, unfortunately, overwrite any custom artwork). That setting controls the actual thumbnails stored in the database. The size that's delivered to the TV is controlled in the device profile and that JPEG_TN setting is the one to tweak - it controls thumbnails for all modes (audio/video/photo). Of course the TV may resize the thumbnail further once it receives it...

Sound good thanks. when i change the resolution in the Options, do i have to run Maitenance for all, or can i just update one of my videos covers manually during my tests?
thanks

I'd just test it on one cover (I'd create a normal playlist, put one file in it and experiment away ).

Thanks Dennis, i did exactly that and tested on just 1 playlist and ran maintenance at each step.

For what it's worth (and sorry to be a pain i know it's not that important its just bugging the heck out of me), not matter what i do the cover image on the TV video list looks the exact same. bad and blocky. The only way the artwork changes appearance is to change the actual source image resolution and reassign. All the following makes no difference at all:

- Change Artwork Thumbnail Width and Height figures in Tools, Options, General. to the same as jpg
- Change Thumbnail sizes in Tools, Browsing Files, thumbail sizes (i know it doesnt matter about this one)
- Change device profile jpeg_tn to the same resolution as the jpg.

maybe someone else can post their experience with the Samsung C series. A jpg of 108x65 seems to be the best but i know for sure the onscreen version is more like 216x130.

as before, no rush, i know you're busy

Ok, to confirm whether the changes are taking effect, try renaming the .mzt file in Thumbnails folder (under the Transcoding folder) to .jpg and see what dimensions that is. Also, I'd check the logs to make sure the JPEG_TN is delivered with the new dimensions specified.

It's possible that the old thumbnail files are being used instead of the new ones (if you haven't cleared out the transcoding\thumbnails folders), so perhaps that's the issue here.
