Chronos adding"zoom animation" to a rough cut

Summary:
When converting 4K 25p footage to 59.94 fps using Chronos, the AI introduces an unwanted zooming artifact during jump cuts within the same camera angle.

Steps to Reproduce:

  1. Source footage: 4K, 25p interview.
  2. Performed a jump cut by zooming in on the same character (no angle change).
  3. Used Chronos to interpolate to 59.94 fps.

Observed Behavior:

  • Chronos interprets the jump cut as a deliberate zoom-in motion.
  • As a result, it introduces a smooth zoom animation between the two cuts.
  • This effect is undesirable because the intention was to create a rough jump cut, not a continuous zoom.

Expected Behavior:

  • The AI should detect that the cut is an intentional edit and not interpolate motion across it.
  • No zoom animation or transitional artifacts should be applied between two fixed-angle shots with different crop levels.

Impact: This behavior compromises the intended editorial style and pacing, especially in interviews and documentary-style content where jump cuts are used for narrative flow.

Let me know if you’d like to add logs, footage links, or adjust the tone (technical vs casual). I can also format it into a formal bug submission if you’re sending it through a support ticket or dev forum.

This sounds interesting and not something that we have really seen.

Can you share the exported video and the original source file so we can take look at what is going on?

Not really a solution, but as an (admittedly quite ugly/awkward) workaround you could split the original video at the cut points and then do Chronos separately on those smaller excerpts and after that join them again.
