Short answer: draft and iterate with LTX-2, move to Kling 3.0 when the clip needs multi-shot storytelling, and use Seedance 2 Fast when the motion has to follow a reference video or a music track.
All three models run in NewYouGo Studio from one account and one credit balance, and all three can start from a still image. They are built for different jobs, though, and they cost very different amounts per clip. This guide compares them on what you actually choose between: input modes, length, framing, sound, and credits.
About the numbers in this post: every duration, setting and credit figure below was read from the live NewYouGo model pages and studio defaults on October 29, 2026. Credits are as shown on the model page; confirm on the page before you run. The studio recalculates the cost every time you change length, resolution, mode or render tier.
Side-by-side comparison

| Image input | One start image | Up to 2 reference frames (guide the opening and ending), max 15 MB each | One anchor image |
| Other references | — | — | Up to 3 reference videos per request (15 s combined); one mp3 or wav reference audio file |
| Duration | 5–20 s (default 5 s) | 3–15 s (default 5 s); Multi Shot splits up to 4 shots inside that range | 4–15 s (default 8 s) |
| Resolution | 480p / 720p / 1080p (default 480p) | Std or Pro render tier (page does not list pixel resolution) | 480p / 720p (default 720p) |

*Credits as shown on the model page on October 29, 2026; confirm on the page before you run. For LTX-2, the pricing table lists 60 / 80 / 120 credits for a 5-second clip at 480p / 720p / 1080p. Switching Seedance 2 Fast from Text to Video to Image to Video or Reference Video changes the cost, and Kling 3.0 Pro costs more per second than Std; the studio shows the new figure before you generate.
How to read the table: the gap between 60 and 400–672 credits is the whole reason to plan your runs. LTX-2 is where you answer "does this framing work?" Kling 3.0 and Seedance 2 Fast are where you answer "is this the final clip?"
When to pick each model
LTX-2: drafts, framing checks and longer simple loops
LTX-2 is the default model on the AI Video Generator page. It does text-to-video and image-to-video with three controls under Advanced options: resolution, aspect ratio and duration (drag between 5 and 20 seconds).
Use it when you want to:
- Check whether a product photo or character still animates cleanly before you commit more credits.
- Test camera moves (slow push-in, pan, static) with the same start image.
- Try a few prompt wordings side by side.
- Make a longer, simple ambient loop. LTX-2 is the only one of the three that goes past 15 seconds in one render.
What it does not do on this page: no multi-shot structure, no reference video and no audio track. If the clip needs those, plan to upgrade.
Kling 3.0: multi-shot storytelling and start/end frame control
Kling 3.0 Video is set up for short sequences that need direction rather than a single moving image. You can stay in Single Shot (3–15 seconds) or switch to Multi Shot, where each beat gets its own prompt and duration, up to four shots within the same 15-second limit.
What it adds for image-to-video work:
- Two reference frames. Upload one image to anchor the opening frame, or two to guide both the opening and the ending. That is useful for product reveals ("start on the closed box, end on the product in hand") and for keeping a character's identity steady across a cut.
- Std or Pro. The page recommends Std for faster iteration and earlier concept passes, and Pro once the direction is settled and you want a cleaner final result.
- Sound Effects. On by default. Keep it on if you want built-in audio energy in the clip; switch it off if you will do sound design in your editor.
The model page also notes its main limit: it is a short-form model. Results hold up when the clip structure stays focused, not when a long story is forced into one 15-second render.
Seedance 2 Fast: follow a reference video or music timing
Seedance 2 Fast keeps three modes in one studio: Text to Video, Image to Video and Reference Video. Its strength is guidance. Instead of describing motion only in words, you can show it.
- Reference Video: add up to three short clips (15 seconds combined) when the motion, timing or camera behavior already has a target, such as a dance move, a product spin you shot on your phone, or a handheld walk-through.
- Reference Audio: upload one mp3 or wav file to guide rhythm, pacing or mood. On the live studio today, this upload is offered with the Reference Video mode.
- Image to Video: use one anchor image when identity, the starting frame or product framing needs to stay close to a chosen visual.
- Delivery formats: six aspect ratios cover vertical (9:16, 3:4), square (1:1), standard (4:3), widescreen (16:9) and cinematic (21:9), at 480p or 720p.
Generated audio is on by default, and the page default is an 8-second clip, which suits social cuts that land on a beat.
Three scenario prompts (one per model)
Copy these as starting points. Replace the bracketed parts with your own subject.
1. LTX-2: framing test for a product still
Settings: Image to Video, 5 s, 480p, 16:9. Credits as shown on the page (60 at these settings on October 29, 2026).
Slow, steady push-in on [a matte black ceramic coffee mug] standing on a light oak table. Soft morning light from a window on the left, gentle steam rising from the cup. The camera moves forward smoothly, no cuts, no shake. Background stays softly out of focus. Keep the mug's shape, color and logo exactly as in the image.
Why it works: one subject, one camera move, one light source. If the mug warps or the logo drifts here, fix the image or the prompt before you spend more credits on another model.
2. Kling 3.0: two-shot product story (Multi Shot)
Settings: Image to Video with two reference frames (opening: closed gift box; ending: product in hand), Multi Shot, 16:9 or 9:16, Std for the first pass. Credits as shown on the model page; confirm on the page before you run.
Shot 1 (3 s): Close-up of a [kraft-paper gift box] on a marble counter. A hand enters the frame and lifts the lid slowly; warm light spills out. Camera holds steady, shallow depth of field.
Shot 2 (3 s): Cut to a medium shot. The hand lifts [a silver wireless earbud case] out of the box and turns it toward the camera. Slow orbit to the right, soft highlight sweeping across the metal. End on the case centered in frame.
Why it works: each shot has one action and one camera instruction, and the two reference frames pin down where the sequence starts and ends. Once the pacing is right, re-run the same shots in Pro.
3. Seedance 2 Fast: motion matched to a reference clip and a beat
Settings: Reference Video (your phone clip of the move), Reference Audio (your mp3 or wav), 8 s, 720p, 9:16. Credits as shown on the model page; confirm on the page before you run.
A young woman in [a yellow rain jacket] on a wet city street at night, neon reflections on the pavement. Match the walking rhythm and camera movement of the reference video. Cut the motion to the beat of the reference audio: a step on each downbeat, a turn toward the camera on the final hit. Vertical framing, subject centered, light rain.
Why it works: the reference video carries the motion and camera feel, the audio carries the timing, and the prompt only has to describe the look. That is far more reliable than trying to describe a dance or a beat drop in words alone.
Workflow: test the framing cheaply on LTX-2, then upgrade
You will get better results for fewer credits if you split the job into a draft stage and a final stage.
- Prepare one clean start image. Clear subject, simple background, the framing you actually want in the first frame. If you need to clean it up first, the image tools on NewYouGo (background remover, upscaler, image editing) can help.
- Draft on LTX-2 at 480p, 5 seconds. Run the image with two or three prompt variations: different camera moves, different motion strength. At the page default this is 60 credits per run.
- Check three moments in each draft: the first second, the middle and the last second. Faces, hands, text and logos tend to drift in the second half of a clip, so look there first.
- Lock the prompt. Keep the wording that held the subject steady and gave you the camera move you wanted.
- Pick the finishing model by job:
- Needs a sequence of beats or a defined end frame → Kling 3.0 (start in Std, finish in Pro).
- Needs to follow a reference motion, a beat or a vertical/cinematic format → Seedance 2 Fast.
- Simple motion that already looks right → re-run on LTX-2 at 720p or 1080p.
- Keep the inputs identical when you upgrade: same start image, same aspect ratio, same core prompt. Change one thing at a time so you know what made the difference.
- Check the credit line before you click generate. Every studio shows the cost next to the button and updates it as you change settings. Plan and credit details are on the pricing page.
FAQ
How long can each video be?
On October 29, 2026 the studios allowed: LTX-2, 5–20 seconds (default 5); Kling 3.0, 3–15 seconds for a single shot, with Multi Shot splitting up to four shots inside that range (default 5); Seedance 2 Fast, 4–15 seconds (default 8). If you need more than 15 seconds of continuous simple motion, LTX-2 is the option among these three; for longer stories, render several short clips and edit them together.
Which model gives me audio?
Kling 3.0 has a Sound Effects toggle that is on by default. Seedance 2 Fast generates audio by default and also accepts one mp3 or wav reference audio file to guide rhythm and pacing (offered with Reference Video mode in the live studio today). LTX-2 on the AI Video Generator page does not offer an audio option, so add sound in your editor.
Which aspect ratios are available?
Kling 3.0 offers 16:9, 9:16 and 1:1. Seedance 2 Fast offers six: 16:9, 4:3, 1:1, 3:4, 9:16 and 21:9. LTX-2 defaults to 16:9, with other options under Advanced options. For image-to-video, match your start image to the ratio you pick so the model does not have to invent extra edges.
How many credits does a clip cost?
At the page defaults on October 29, 2026: LTX-2, 60 credits (5 s, 480p; the pricing table lists 80 for 720p and 120 for 1080p); Kling 3.0, 400 credits (5 s, Std); Seedance 2 Fast, 672 credits (8 s, 720p, text-to-video). Costs change with duration, resolution, mode (for example Image to Video or Reference Video on Seedance 2 Fast) and render tier (Std or Pro on Kling 3.0). Credits as shown on the model page; confirm on the page before you run.
Should I use Kling 3.0 Std or Pro?
The Kling 3.0 page suggests Std for faster prompt iteration and early passes, and Pro once you know the direction and want a cleaner final result. Pro costs more per second, so get the pacing right in Std first.
Can I use the same image on all three models?
Yes. All three accept an image as the starting point. Keeping the same image and aspect ratio across models is the simplest way to compare them fairly.
