LRTimelapse 4.7.5 – This is new

LRTimelapse 4.7.5 is out and it brings a lot of improvements. I’ve been working hard on this release in the last weeks to get it out as soon as possible.

Especially the improved support for external ramping tools like the timelapse+ View and improvements for working with Cinema-DNG files were things that I wanted to get to you as soon as possible. The windows version does not need java installed anymore (likewise as on mac) and along with this, I’ve fixed and improved several things to make your workflow easier and more streamlined. For example, I’ve managed to significantly speed up the initial preview generation and import for several cameras, including Canon and Fuji.

Check out the details:


  • Considerably sped up preview loading for several cameras (for example canon, fuji etc.)
  • Added preview support for (Cinema)-DNG files, that do not have any camera previews embedded. The raw files have to be demosaiced for this, so it’s slower as the normal preview extraction. But this is the only way to get the regular previews for such images like Cinema DNG (visual previews have always worked!).
  • Using systems temp folder for preview conversions now, this might speed up visual preview generation when working on slow drives like network drives.


  • Users with a private License can now control the number of threads used when creating the visual previews, like pro users. The setting is in the Expert Settings.
  • Increased the number of possible threads to 24.

Support for external ramping devices

  • Improved support for external rampers like Timelapse+ View or RamperPro
  • Added a dialog when external xmp corrections from one of those devices exist and the user tries to invoke the holy grail wizard. In that case, the external corrections would be overwritten by LRTimelapse’s Holy Grail wizard. Both usually provide very similar results. Now the user can decide, if he wants to use the external corrections, or LRTimelapse’s Holy Grail Wizard.
  • When the external corrections are being migrated to LRTimelapse’s background layer (to enable keyframing of the exposure), the old exposure column was not always cleared, fixed.


  • Added missing support for parameter “Color Noise Reduction Smoothness”.
  • Metadata/Initialize in some cases left some old edits. It will now reset everything to a clean starting point, as expected.
  • Clear Metadata will now really clear everything. You can then save and exit the sequence. If you want to continue working on it, you have to re-initialize it via Metadata/Initialize. There will be a dialog telling you this.
  • Added the column “RAW Quality” to the table. It’s correlated to the white balance treatment. RAW means “Absolute WB Treatment”, FLAT means “Relative WB Treatment”.
  • Inconsistent white balance treatment in a sequence is now being detected and the user gets a popup asking to define the sequence mode.
  • Added Date-Time support for (some types of) Cinema DNG files.


  • Windows 64bit: Like on mac, no individual Java install is needed anymore on Windows 64. That means, if you only needed Java for LRTimelapse, you can uninstall it now via control panel.
  • Windows 64bit: LRTimelapse will now be installed into Program Files\LRTimelapse 4 – not anymore into the 32bit folder Program Files (x86). Therefore, please uninstall any former LRTimelapse before installing 4.7.5.
  • Windows 32 bit: On a 32bit windows, you’ll still need to install java manually, then use the launcher “LRTimelapse 4_32bit” from start menu. Please note that 32bit usage is not tested and officially not supported anymore and will soon be removed competely.
  • On some Windows systems where LRT3 was still installed, the paths to the external tools could have pointed to the old LRT3 variants. This will now be automatically detected and fixed.
  • Sequence properties sometimes failed to save. Fixed.
  • Updated all external tools to the latest versions.

Video Export and rendering

  • Added an option to the advanced options of the LRTExport pluing, to force exporting the intermediary sequence in sRGB color gamut instead of AdobeRGB. This is only a fallback for users on older systems that experience color problems with the default wide-gamut workflow.
  • LRTimelapse Render dialog will automatically detect if the intermediary sequence was rendered in sRGB or AdobeRGB and switch between Wide Gamut (BT2020) and Standard (BT709) color space.
  • When the video encoder produces an error, the “ding”-sound will not be played anymore and the explorer/finder not opened.
  • The Low Quality setting on h.264 and h.265 rendered with higher quality than MQ. Fixed.
  • Filename sort will now be forced, when date/time exif data is not complete.

User interface

  • Fixed wrong Preview-Lum column display when no camera previews were found in the files.
  • Sequences without Exif-Data or incomplete Date/Time records did not always switch automatically to filename-sort. Fixed.

Make sure to update as soon as possible. Just install the new version over the old one. As always, all 4.x.x releases are free updates for users with a LRT4 license.
