About eventvideo
Personalized. Automated. Delivered Same Day.
eventvideo.at is the B2B service of groox FILMPRODUKTION GmbH for sports event organizers – personalized participant videos since 2017, powered by iRewind. Exclusive provider of this service in Austria since 2018. The service is commissioned by the event organizer.
Your participants share their personal video an average of 3 times — organic reach for your event without ad spend. With 5,000 participants, that's roughly 15,000 organic impressions at zero ad cost. They download it, forward it, and post it multiple times across social media.
Normally up to 6 selected points along the course are recorded with special cameras connected to the timing system and uploaded directly to our editing system.
The iRewind platform scales to any event size: from regional runs to the Paris Marathon with 52,000 runners or the ASICS Milan Marathon with 22,000 participants.
Beyond the core package (personalized participant videos), optional add-ons are available depending on event size: aftermovie within 24h, live highlights on the video wall, social media packages, and TV features (e.g. ORF SPORT+).
