Bug ID: 478315 Summary: Keyframe interpolation modes, In and Out concepts wrong. Classification: Applications Product: kdenlive Version: git-master Platform: Other OS: Other Status: REPORTED Severity: normal Priority: NOR Component: Effects & Transitions Assignee: j...@kdenlive.org Reporter: gabcor...@gmail.com Target Milestone: --- Created attachment 164047 --> https://bugs.kde.org/attachment.cgi?id=164047&action=edit Adobe After Effects Manual SUMMARY *** When setting keyframe interpolation, the concept of what is considered "In" and what "Out" is wrong, in the current implementation. In: is when the time is "coming in" to the selected keyframe. Out: is when time is "going out" of the selected keyframe. *** ADDITIONAL INFORMATION There are a lot of references to this, but the main ones should probably be Adobe products (After Effects / Premiere Pro) and OpenToonz, all of the using the concept in the right way. A lot of classic animation related textbooks where the concept is explained clearly: Animator's Survival Kit, etc. Here you can see a demo of After Effects Easing In/Out into play: https://www.youtube.com/watch?v=UVox_2py9yU Below I will attach excerpts from the After Effects manual and from Animator's Survival Kit by Richard Williams, explaining the concept. -- You are receiving this mail because: You are watching all bug changes.
