So which city has the best Amazon pitch video?

The deadline has passed for cities to submit their confidential proposals to be Amazon.com's second headquarters, but their video bids — many of which were posted publicly online — will live online for a while.

Here's a look at seven of them:

Detroit's video — its second since it began bidding for HQ2 — is 3 minutes, 40 seconds. The poetic narration and high-energy images emphasize the area's place in history as a place that moves. It ends with the tagline: "Move Here. Move the World."

Boston's video, which is just under 2 minutes, has a shipping theme with no narration and a simple slogan: "Boston. Yes." It emphasizes its East Coast locale. It goes down a checkoff list: Airport. Check. Talent. Check. Public transportation. Check. And features a rendering of what a headquarters complex there could look like.

Pittsburgh's video takes a documentary approach. It uses the tagline: "Future. Forged. For all." In 2 minutes, 20 seconds, it connects its past as a city that made steel and "built America, built the world" to its future as a "tech powerhouse." Like Detroit's video, it has nostalgic narration. It starts with a black-and-white clip. It ends with a warning: "Hurry. Tomorrow is almost here."

Philly's 3-minute, 13-second video is titled Philadelphia Delivers. It touts its momentum, energy and food in a series of soundbites of leaders, celebrities, and locals. it doesn't shy from being gritty, with some keeping-it-real cussing bleeped out. It also takes a subtle swipe at some of the slicker bids with one booster opining that some cities "are trying so hard."

Dallas combined with Fort Worth, known as DFW, has a 1 minute, 41-second video that showcases the area. It also uses the ampersand, seemingly as a symbol of expansion and partnership. Throughout the video, folks hold handwritten placards that tout the area's virtues and attributes: progressive, unique, family, outgoing, pride, talent, growth, diversity, vibrant, easy innovation. It ends "amzn & dfw."

In its 5-minute, 10-second video, Las Vegas uses an Alexa-like voice, a nod to Amazon's talking digital personal assistant. Alexa says Las Vegas is a "spectacular, fast-track city built on hopes and dreams — and a bit of moxie." It acknowledges its resilience to recent tragedy with #VegasStrong, and contrasts its busy Strip with its natural surroundings.

Atlanta's video — which is 1 minute, 12 seconds — simply documents a trip from Atlanta to Seattle to supposedly hand-deliver the city's proposal. There's no narration, mostly just all-caps headlines: BUSINESS FRIENDLY, TALENT, TRANSIT ACCESS, CONNECTIVITY, INNOVATION. It ends: "DAY ONE STARTS NOW."
