OTIO export/import does not preserve speed keyframes (time remapping keyframes) in Premiere Pro

Hello Adobe Premiere Pro team,

I would like to report an issue with OTIO export/import in Premiere Pro.

I tested OTIO round-trip behavior using a sequence that contains both transform keyframes and speed keyframes (time remapping keyframes).

What I tested

• I created clips in Premiere Pro with:

   

  • Transform keyframes (position / scale / rotation)

  • Speed keyframes (time remapping / variable speed)

   

• I exported the sequence as OTIO

• Then I re-imported the exported OTIO back into Premiere Pro

Result

• Transform keyframes were preserved correctly

• However, speed keyframes were not preserved

• In other words, time remapping keyframes were lost during OTIO export/import round-trip

Expected result

• OTIO export/import should preserve speed keyframes, just like transform keyframes

• At minimum, Premiere Pro should be able to round-trip its own OTIO export without losing time remapping keyframe information

Actual result

• Edit order, cuts, and some other basic information are preserved

• Transform keyframes are preserved

• But speed keyframes are not restored after re-import

Why this matters

OTIO is becoming increasingly important for interchange between editing and finishing systems.

Many users are expecting reliable workflow exchange between applications such as:

• Adobe Premiere Pro

• DaVinci Resolve

• Avid Media Composer

At the moment, transform animation seems to be exported, but time remapping keyframes do not appear to survive the OTIO round-trip in Premiere Pro. This makes high-precision OTIO-based workflows difficult for real production use.

I strongly hope Adobe will improve this behavior and help support highly accurate OTIO interchange between Premiere Pro, DaVinci Resolve (Blackmagic Design), and Media Composer (Avid).

Thank you for your work on OTIO support, and I hope this can be improved in a future update.
