...seems to destroy the embedded timestamps that PTV uses to start video playback at a specific position.

Don't know how this file stamps are stored, but it might be solution to apply an empty file rating to the generated file so that setting the file rating to a specific value does regenerate or restructure the metadata. Just by applying a file rating to a thumbnail sheet the file size jumps up by 6kb...

OS: Windows 10 19041.330
VTM: 15.0 64Bit
PTV: 5.0 64Bit
  • Produce a JPG thumbnail sheet with VTM
  • Verify, that by opening the JPG file with PTV, right clicking on a thumb, there is the "Start Video" contextmenu entry
  • Locate the thumbnail sheet in windows explorer
  • Show details pane in windows explorer (view > details pane)
  • Select the JPG file
  • Set rating to three stars in details pane
  • Click Save/Apply
  • Reopen the JPG file in PTV and try the contextmenu on a thumbnail, the "Start video" entry is gone

Hi,
I'm going to guess they mean when applying an EXIF rating to the jpg external to Videonizer which looks to overwrite the time code meta-data VTM puts into the files.

The best workaround I found was to start using "xmp sidecar files" which leave the original jpg completely untouched so the time codes aren't disturbed but still allows me to add whatever other metadata I want "to" a picture. (I import/export Videonizer data to the xmp files which gives me other ways to works with the Videonizer data outside of Videonizer.)

The downside is there's another file floating around to be aware of, but since everything is sorted out into directories anyway (along with associated multifiles and etc) it's just one more and adds some nice flexibility.

Ok,

Yes, a third party tool can overwrite JPEG info.
So please consider bastage's workaround.

Yes, that will work, but has imho several disadvantages...

- It requires additional software to write the xmp file
- Another file floating around
- Windows Explorer does not support reading/writing xmp files
