Those of you running 20+ min sessions, how are you saving/uploading video? I tried at Putnam last month and lost all video or it wouldn't save. Going to Mid-Ohio on Thursday and don't want a repeat! I'm running iPhone 4S 16GB and can bring my PC to save and clear to after each session. Any idea file size for video with or without overlay?
Edit: I think I found my answer on the HLT website.
