From e0f8107e1d721010f66d483e2e2f9fca34d64ffa Mon Sep 17 00:00:00 2001 From: Jeff Emmett Date: Sun, 30 Nov 2025 18:51:41 -0800 Subject: [PATCH] fix: increase VideoGen timeout to 6 minutes for GPU cold starts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Video generation on RunPod can take significant time: - GPU cold start: 30-120 seconds - Model loading: 30-60 seconds - Generation: 60-180 seconds Increased polling timeout from 4 to 6 minutes and updated UI to set proper expectations for users. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/automerge/AutomergeToTLStore.ts | 11 +++++----- src/automerge/useAutomergeSyncRepo.ts | 31 ++++++++++++++++----------- src/shapes/VideoGenShapeUtil.tsx | 14 +++++++++--- worker/AutomergeDurableObject.ts | 19 ++++++++++++---- 4 files changed, 50 insertions(+), 25 deletions(-) diff --git a/src/automerge/AutomergeToTLStore.ts b/src/automerge/AutomergeToTLStore.ts index bd5e022..7081abe 100644 --- a/src/automerge/AutomergeToTLStore.ts +++ b/src/automerge/AutomergeToTLStore.ts @@ -620,11 +620,12 @@ export function sanitizeRecord(record: any): TLRecord { sanitized.meta = { ...sanitized.meta } } // CRITICAL: IndexKey must follow tldraw's fractional indexing format -
