Note that in the NKSC_PARAM folder there is a. The missing-thumbnail behavior is the same whether I add files by drag-n-drop or the "Add files." button.įor the Nikon files, I've attached a screenshot of what the directory looks like after adding metadata to a bunch of Nikon raw NEF files. Dropping additional files then will trigger most or all of the missing thumbnails to get generated, but sometimes one will still be missing. They will not fill in when I stop scrolling. If I drop 30 files on the window and then grab the vertical scroll bar control and start moving it (or just mouse-scroll), it will reliably cause many of the thumbnails to not get generated, as many as 90% with aggressive mouse-scrolling. But if I afterward drop one or a few more files, it will trigger generation of the missing thumbnail. If I drop 10-30 files on it, often the very first one (top left in the list) does not get a thumbnail generated. The crash is sporadic and it does not actually seem to be a specific file - I have gotten it to happen maybe half a dozen times, but it won't die if I'm only dropping a single file.ĭuring the investigation I've found some more frequent and highly repeatable anomalies in thumbnail generation. I have other reasons for wanting to dump ViewNx-i out of my workflow (horrible performance on network drives) but I thought I should still report this. Older versions of ViewNx embedded the metadata. NKSC_PARAM/ and XnConvert doesn't look there. I'm basically sure this happens because ViewNx-i now stores metadata in a sidecar file inside. I can view them all in Mac Preview so it doesn't seem fundamentally corrupt.ģ) If I add metadata tags with Nikon ViewNx-i, the metadata is not copied over into the. I'm trying to isolate the specific file from the batch but that's tedious, though I imagine you'll want the file. It looks like this happens while XnConvert is generating the preview thumbnails for the input tab. tiff that kills XnConvert instantly when you add it to the Input tab (before I even try to convert it) you get the "XnConvert has quit unexpectedly" system dialog. However, if I set it to "best quality", the problem goes away.Ģ) I have at least one. Here are the issues:ġ) With the jpg "subsampling factor" at default, many images get a big diagonal shear. They are from an Epson 4990 scanner using Image Capture on the Mac. tiffs are good sized (4Kx3K, 35-38MB) and I am doing a 100% quality conversion. jpg with 1.83 on a new 2020 MacBook Pro running Catalina. I've hit a few new gremlins converting some scanned. New forum user here, though I've been using XnConvert for quite a while (BTW thanks for fixing dark mode!!).
