Lossy DNG
« on: June 16, 2024, 07:32:25 am »
I recently used Lightroom to convert all of my jpegs to lossy DNG files but it seems that media center is unable to decode (playback) or make thumbnails for these files.

I am happy to provide samples if necessary

Genuine question: what do you gain with this conversion?

Lightroom was having trouble saving some metadata changes to some files. Convert to dng seemed to fix them. Also i think that any xmp changes (lightroom adjustments) will get saved inside the dng rather than a sidecar xmp file, which is preferential to me. Finally, i am not 100%, but i think that the embedded thumbnail that lightroom creates (eg, the nice looking post edited file) will also be used by media center or other external apps when opening the files.
This seems to be the case for all of my raw anyway. For the jpegs it has made them unreadablein Media Center

Hi all,

It seems strange to me that Media Center cant display these types of files.

If i browse these files in explorer it can both show me thubmnails and the windows photo app can open them. Lightrooom obviously can open them. Google photos imports and displays them ok. Its only media center that cant
