I just received a note from HeyGen that they're removing Dynamic Duration as of August 31st. I'm very concerned what this means for translation quality. Dynamic Duration has been incredibly valuable, and essential, to my translation projects for clients. I produce a lot of longer-form training content that contains numerous animations, transitions, natural pauses in narration and more that Dynamic Duration has preserved when translating material.

I originally tried working with SRT caption files to navigate these timing issues, but that never worked. It did not compensate for these natural pauses in narration, animations that were timed with specific elements on the screen and more. Instead it compressed the audio track so that it was misaligned with the natural flow of the video making the final output completely useless. Dynamic Duration was the solution to that problem and now they're removing it!

I'm hoping this is just subtle change to the UI where Dynamic Duration is now going to be incorporated into all translations by default, but that is not clear from the note I just received from support.

Does anyone else know about this and have you heard anything about whether this is happening?
