This app helps you create beautiful flicker-free sunset, cloud, city scape, and day to night time lapse easily. Shoot in auto-exposure modes, TLDF will remove the flickers for you!

Key Features:
1. Most advanced deflickering algorithm for timelapse. Non-linear adjustment of pixel brightness.
2. Noise Reduction and Blending (lighten and average).
3. Partial Noise Reduction or Blending: Choose the area where you want to apply noise reduction or blending with masking features.
4. Edit key frames and TLDF interpolates intermediate frames for smooth transition. The edit feature includes: color temperature, tint, vibrance, saturation, exposure, contrast, highlight, and shadow adjustments.
5. Set Reference Area for optimal deflickering. For most cases, it is not necessary to use this feature. Use it when large area of image is naturally flickering (e.g. shadow of clouds on ground, reflection of sky on moving ocean tide, and large artificial lights that turn on and off). Set the reference area to exclude the area where natural flickering occurs.
6. Support RAW and most of the popular image formats as input. Also support video as input.
7. Supports Wide-Color Gamut color profiles. Outputs sRGB, Adobe RGB, Display P3 for images, Rec.709, P3, Rec.2020 for videos.
8. Output highest quality JPEG images and lossless 8-bit or 16-bit PNG and TIFF images. The output images have the same size as the input images.
9. Output video in H.264 (up to 4K), 10-bit H.265 (HEVC), ProRes 422 HQ, and ProRes 4444 with resolution up to 8K. ProRes codecs generate video with 10+ bits per pixel.
10. 16-bit Editing and Input/Output. For input that has more than 8-bit color depth including ProRes videos and 16-bit RAW or images TLDF will automatically edit them with 16-bit color depth.
11. Support for multi-core CPUs. TLDF automatically detects the number of cores in your CPU and take advantage of them by rendering in parallel.

The following are a few example workflows:
Option 1 (Fast): Import JPEG images -> Edit and Preview -> Render and Output JPEG and/or H.264 or HEVC videos.
Option 2 (High Quality): Import RAW images -> Edit and Preview -> Render and Output 16-bit PNG,TIFF and/or high bit-depth HEVC, ProRes 422 or ProRes 4444 videos.

What’s New

Version 2.5.1

Users can choose scratch folder (optional). When there is not enough hard disk space on the main disk, users can choose a folder on external hard drive where TLDF stores temporary files. Make sure the scratch folder doesn't include important files. TLDF will automatically delete temporary files in the scratch folder.

Fantastic App with one fatal flaw

This small app is a huge help and the pro feature like pro res 4444 and rec 2020 are amazing. It works on stuff that is stationarry, but does struggle with some timelapses of a sunset I took while driving. Totally understandable though since the exposure is a little all over the place.

However, the way it processes the photos into a video file and renders them out does give me some issues. It seems like it’s building the file on my computers hard drive when rentering before movie it to the external drive I wanted it saved to. This means that if I’ve got a long video in pro res 4444 I can very easily run out of space on my hard drive for rendering.

Other than that though, it’s perfect.

Exactly what I needed

This app does just what it says. I’d recommend trying the free version first, and if you like it pick up this version.

I’ve searched for apps to remove timelapse flicker, and they all seem to either be for Windows or are expensive/complicated and geared towards professionals. Until I stumbled upon this, there didn’t seem to be anything for a hobbest who just wanted a flicker-free timelapse. Yesterday morning I decided to create a timelapse and then as I was reviewing the results I remembered why I originally stopped making them - the stupid flickering. Really happy I found this!

This app did not improve my time lapses

I worked very hard trying to get this app to improve minor flicker in two different image sequences. It either left the sequence about the same or made it worse (more flickery). I tried TLDF on large file-size image sequences, reduced file-size image sequences, on video files produced from both TLDF and non-TLDF image sequences (yes, I tried running it twice), and it never really improved the flicker. To make things worse, on a dark sequence it added-in very large blobs of noise. I wasted hours of time trying this out.

And there is no help or manual to speak of.

Developer Response ,

I am sorry that TLDF didn't help improve your sequence. Is it possible for you to upload the files (60 frames should be enough) to Google Drive or Dropbox for me to see? You can email (you can find it on our support page) the link to me. In the meantime, please try TLDF on other time lapse sequences. I hope you can find better luck :)
