Tavus lists 1080p conversational video; Sume avatar clips are 720p

Tavus's pricing page lists 1080p resolution and 24 kHz audio fidelity as part of its conversational video interface on every plan, while its Griffin page says the research-preview Griffin-Lite generates 720p video in 320 ms chunks and is not available to customers yet. Sume's avatar talking video has a resolution of 720p today. So the number to compare is the shipped one: 1080p for Tavus's conversation product, 720p for Sume's rendered clips.

What each page states

Be careful to keep the products apart: the pricing page describes the shipping conversational interface, and the Griffin page describes a model that is a preview for selected testers.

Does 720p matter for your placement

For a 9:16 phone feed, 720p wide by 1280 tall is the common floor and looks fine on a handset. For a 16:9 web hero shown full screen on a large monitor, the gap shows. Decide from where the clip plays, not from the spec sheet.

• Phone feeds and chat: 720p is usually enough.
• Full-screen desktop: check on the real display.
• Paid placements: read the platform's minimums before you render.

What Sume offers instead of more pixels

Quality tiers (standard, plus, max) change the render path, not the output size. Previews let you check framing before the render. If you need a bigger file, test an upscale as a separate step and judge whether it adds real detail or only size.

Bottom line

Pick on use: live conversation at 1080p points to Tavus; script-driven presenter clips at 720p fit Sume. Keep Griffin-Lite out of any plan until it is available to customers.
