Google Ads documented its recommended video ad specifications, advising the upload of .MPG (MPEG-2 or MPEG-4) format videos. The guidelines also list other supported video formats including .WMV, .AVI, .MOV, .FLV, and .MPEG-1.
For streaming teams running video campaigns through Google Ads, the practical issue is file prep: the platform now documents .MPG as the recommended upload format, with several legacy formats still supported. That makes encoding choices more explicit for ad ops and post-production workflows. The broader signal is that Google Ads is clarifying accepted video containers and codec families rather than changing the ad product itself. What to watch next is whether Google updates this help page with more detail on file settings, since the current guidance names formats but not resolution, bitrate, or frame rate.
