Twenty-one models on one page looks like a lot of choice until you stop reading the names and start asking what the clip has to do. Is it a draft to test a prompt? A Reel for a D2C brand? A 30-second launch film? A product that must look identical in every frame? Each of those has a clear answer in the AI Video Generator, and the wrong answer mostly costs you money rather than quality. This post groups every model by job, puts them in one table, and ends with the rules I use to choose. Prices are in credits, where 1 credit is ₹0.50, as of October 2026.
Start with the job, not the model name
Model names tell you very little. What matters is five things: what the model takes as input (text, an image, references, an existing video), how long a clip it can make, what resolution it outputs, whether it makes sound, and what it charges per second. Most of the 21 models are specialists in one of those, and the picker on the page already sorts them by what they are good at. The table below does the same, with the "for 5 seconds" cost so you can compare like with like.
| Job | Model | Max length | Resolution | 5-s cost (credits) |
|---|---|---|---|---|
| Cheapest drafts | Nova Lite | 10 s | 768p | 40 |
| Cheapest drafts | Orbit 3 | 30 s | 480p to 1080p | 70 at 480p |
| Cheapest drafts | Lumen Motion 2.5 | 10 s | 720p or 1080p | 60 at 720p |
| Everyday all-rounder | Lumen Motion 3 Standard | 15 s | 720p or 1080p | 115 |
| Sharpest frame | Nova 2K | 15 s | 2K | 175 |
| Cinematic, longest | Vela 2.5 | 30 s | 480p to 1080p | 385 at 480p, 2,105 at 1080p |
| Cinematic 4K | Vela 2.0 | 15 s | 480p to 4K | 265 at 480p, 2,875 at 4K |
| Cinematic, auto direction | Director 4 | 30 s | 480p or 720p | 545 at 480p |
| Camera moves | Pulse Fast | 10 s | 720p to 4K | 240 at 720p |
| Camera moves | Pulse Pro | 10 s | 720p or 1080p | 320 at 720p |
| First + last frame | Lumen Frames | 15 s | default | 115 |
| First + last frame | Lumen Omni | 10 s | default | 150 |
| First + last frame | Prism 6 | 15 s | 1080p | 260 |
| Consistent characters | Orbit 2.7 | 15 s | 720p or 1080p | 135 at 720p |
| References | Canter 1.1 | 15 s | 720p or 1080p | 185 at 720p |
| Dialogue and sound | Lumen Motion 2.6 | 10 s | default | 95 |
| Restyle a video | Morph | 30 s | 480p to 1080p | 420 at 480p |
| Fast long clips | Orbit Prime | 30 s | 480p to 1080p | 110 at 480p |
Three models are not in the table because a sibling does the same job better or cheaper: Orbit 2.6 (multi-shot with sound, 15 s, from 135 credits), Canter 1.0 (1080p, 15 s, from 185) and Spark 1.5 (image to video, 1 to 15 s, from 215). They are there if you like their look, but you will rarely need to start with them.
Drafts and everyday clips
Nova Lite is where every new prompt should begin. At 8 credits a second it makes a 6- or 10-second clip with fluid motion for ₹24 to ₹40, which is cheap enough to run a prompt four or five times while you learn what it does. Orbit 3 is the other draft model and the best value if you need length: it goes to 30 seconds with sound, and a 480p clip costs 14 credits a second. Lumen Motion 2.5 is quick and precise at 5 or 10 seconds and is a good draft for anything that will end up on Lumen Motion 3.
Lumen Motion 3 Standard is the all-rounder, and if you only ever learn one model, make it this one. It does text and image to video and motion control, makes multi-shot clips (a 15-second clip can hold three or four scenes) with native sound, and at 115 credits for 5 seconds it is the sweet spot for a Flipkart listing video, a Reel for a Bangalore cafe, or a WhatsApp status for a boutique in Mumbai. Nova 2K is the sharpest single frame on the page, which is what you want when the viewer will pause on a product or a facade. Orbit Prime is the fast one for long clips when you would rather wait less than pay less.
Cinematic and long clips
Vela 2.5 is the most cinematic model and makes the longest clips, up to 30 seconds, with references, edit and extend all supported. It is expensive at 1080p (2,105 credits for 5 seconds) and much less so at 480p (385), so draft at 480p and go up only for the final. Vela 2.0 is the only route to 4K on a cinematic model, at 575 credits a second, and tops out at 15 seconds; use it for a launch film that will play on an LED wall, not for Shorts. Director 4 is text to video only and directs the scenes itself, which is useful when you want a 30-second story and do not want to write four shots. It has no image input, so it cannot start from your photo.
Control: camera moves, frames and references
Pulse Fast and Pulse Pro are built for camera moves. If the clip is about the move itself, a crane up over a clubhouse or a whip pan across a shop, these hold the move more reliably than the all-rounders, and Pulse Fast offers 2K and 4K settings.
Lumen Frames, Lumen Omni and Prism 6 all take a first and a last frame. Give them your start photo and the exact view the clip must land on, and they fill the motion in between. That is how you get a clip that begins on an elevation shot and ends on the balcony, or opens on a packed product and closes on it unboxed. Lumen Frames is the cheapest of the three and goes to 15 seconds.
Orbit 2.7 and Canter 1.1 are for consistency. Drop two to four clear reference images of the same person, mascot or product, and the model keeps them recognisable through the clip. That matters for a brand ambassador who must look the same in five Reels, or a bottle that cannot change shape between shots.
Sound, dialogue and restyling
Most models with a sound setting generate ambience, effects and music that follow the motion. Lumen Motion 2.6 is the one tuned for dialogue, so if the prompt asks for someone to speak a line, start there. Morph is different from everything else: it takes a video you already have and restyles it from reference images while keeping the original motion. It is billed on the input length, so trim the clip to the seconds you need before you send it.
Decision rules
First, if the prompt is new, draft on Nova Lite or Orbit 3 at 480p until the motion is right, then switch models without changing a word. Second, if you have a photo and need it to move, use Lumen Motion 3 Standard; if you have a photo and a specific end view, use Lumen Frames. Third, if the same face or product must appear in several clips, use Orbit 2.7 or Canter 1.1 with references. Fourth, go to Vela 2.5 only for a final that will be watched on a big screen, and to 4K only when someone has asked for 4K. Fifth, remember that resolution can be fixed later for free: a 1080p clip resized to 9:16 and converted in the video tools looks fine on a phone, and nobody scrolling Reels will see the difference between 1080p and 2K.
Frequently asked questions
Which AI video model is best for beginners?
Lumen Motion 3 Standard. It handles text and image to video, makes multi-shot clips with sound up to 15 seconds, and costs 115 credits (₹57.50) for 5 seconds. Draft first on Nova Lite or Orbit 3 if you are still shaping the prompt.
Which model makes the longest clip?
Vela 2.5, Orbit 3, Orbit Prime, Director 4 and Morph all go up to 30 seconds. Vela 2.5 is the most cinematic of them; Orbit 3 is the cheapest.
Which model gives the sharpest picture?
Nova 2K for the sharpest single frame at 2K. For true 4K output, Vela 2.0 and Pulse Fast both offer a 4K setting, at a much higher cost per second.
Can I switch models without rewriting the prompt?
Yes. Keep the prompt, the start image and the settings, and change only the model. That is how the draft-then-final workflow works.
