Can I split my run? bc my PS4 only allows <1hour vids

And can I get accepted ending my run before cake pie (on final summit screen?)

The answer to your first question: No, we require one continuous recording. You can stream to twitch and submit a highlight of the streamed run instead of recording it if length is a problem. Just need to make sure to have "Store Past Broadcasts" enabled.

Runs don't require the pie screen to be showed. Seeing the final time in the summit complete screen is enough for submissions
