What kind of ads can I upload?

You can only test YouTube ads on junbi. The reason for this is that junbi’s benchmarking is specifically designed around YouTube ads, and the dataset we use for comparison is based on real YouTube ads that are typically between 5 and 90 seconds long. This duration range is ideal because most YouTube ads fall within this time frame, and testing outside of it might not yield accurate results.


You can upload any .mov .m4v or .mp4 file that is at least 5 seconds, and up to 90 seconds long.


Additionally, junbi supports different viewer modes and ad types, which can influence how your ad performs and is tested. For more details on the supported viewer modes and ad types, you can check the specific articles we have on those topics. This will help you better understand how the testing works and how to optimize your ads for different settings.
