Video resolution is the number of pixels in each frame, written as width×height. The two common AI-video resolutions are 720p (1280×720) and 1080p (1920×1080). Higher resolution costs more to generate and renders slower.

What is video resolution?

By MakeThisVid Editorial Updated Methodology

Resolution affects playback quality and file size. 720p is sufficient for feed video on most social platforms — most viewers watch on mobile where the screen is below 720p anyway. 1080p (Full HD) is the standard for paid ads, landing-page hero video, and any surface larger than feed. On MakeThisVid, 720p costs 1 credit per clip and 1080p costs 2 credits. 1080p clips are fixed at 8 seconds.

Who Uses MakeThisVid for This

Mobile-first feed video

Most viewers watch on screens below 720p — generating higher costs more without changing what they see.

Paid social and pre-roll

1080p reads as professional and avoids the soft look that 720p can have on larger displays.

Landing-page hero clips

1080p is the right baseline for any video embedded on a marketing page where pixel quality is a credibility signal.

No. Most ad placements (TikTok, Reels, YouTube pre-roll, Meta feed) display below 1080p anyway. 1080p is the practical ceiling for AI-generated short-form. 4K is over-spec for most workflows and dramatically more expensive to render.
