, took a while for me to hear your shout; probably that Fall wind out of the west
and I discussed this in another thread. The size and embedding issues are known. I am not familiar with Apple software, so there could be something there. It's true though that I originally had a low percentage of album art displaying until I resized it to 600x600 or less. Now every one displays. As a recap, here are some of the points picked up over the past couple years:
- Uconnect people told me directly in a phone conversation that album art should be embedded JPEG 240 x 158 megapixels (SD Card Recommendations from Uconnect
-@emddd40x said she/he had insider knowledge on the Harman Kardon platform Uconnect is currently built on: - It was never really tested with art beyond 600 x 600 and re-sizes it down for display down to 200 x 200. - It doesn't cache the art. It reads it live each time from the source file. - it's not configured for in-folder art, only embedded art. (SD Card Recommendations from Uconnect
said any album art over 950 x 950 will not display (SD Card Recommendations from Uconnect
). I tested this by adding album art to my SD at 1000 x 1000 and none of that displayed. Resized them to 900 x 900 and they all displayed.
It could be that anything over 240 x 158 causes more Uconnect processing to downsize with no gain in album art fidelity. But I've never tested it. However, I don't see any difference in fidelity between album art at 600 x 600 v.s. 300 x 300 on the Uconnect display.
Many music players as well as PCs have plenty of memory to display high fidelity album art. Uconnect apparently does not. But that stands to reason since only a small portion of the 8.4" diag screen is allocated to album art display. The RA4 has more memory than the RA3. That might also be a factor in album art sizes between the models. But that's just a thought; no one has ever suggested that.
Bottom line, size matters. There is a small and simple Windows program out there that resizes album art in batch mode. You sick it on as many song files as you want and it resizes them all, no sweat. But as the name implies, it only works for MP3 files: Sanse MP3 Art Sizer can be downloaded here: http://hcware.x10host.com/mp3art/
