Current Behaviour

I has some annotated video in one deployment and I am willing to copy this video with annotations on other one. So, I dumped annotations as cvat for video from old and uploaded them to the new. And here is an error.
Other formats like "cvat for images" or "labelme" works fine.
annotations.zip

Your Environment

CVAT version 1.2.0 on both deployments

@PMazarovich, I've failed to reproduce this error. I've created a task with 18300 frames of size 1280x720, segment size 1000 and overlap 5. The annotations were imported after few minutes. Commit id 98e2bf4 (read as current develop after 1.2.0).
