LTX Retake, Extend, Reframe: still 2.3 Pro, $0.10-$0.20 per second

On LTX's API price page, the Retake, Extend and Reframe endpoints are listed under LTX-2.3 Pro, not 2.5, and they bill per second of input video: $0.10 per second for Retake and Extend (1080p only) and $0.10 or $0.20 per second for Reframe at 720p or 1080p output. LTX's own pricing page says Retake, Extend, HDR Upscale and Reframe are billed on the input video.

Cost per job

An 8-second Retake input costs 8 x $0.10 = $0.80. An Extend job is capped at 505 billed frames; at 24 fps that is 505 / 24 = 21.04 seconds, so at most about $2.10. A 60-second Reframe source costs 60 x $0.10 = $6.00 for 720p output or 60 x $0.20 = $12.00 for 1080p output.

Because the bill follows the input, long source clips drive the cost, not the length of the change you want. A 3-second fix inside a 20-second clip is billed for the whole 20 seconds on a Retake, so $2.00. Cut the segment first when you can.

What Sume has for the same jobs

Sume does not list LTX. For reshaping a finished clip, Sume has fixed-fee tools. Video trim is $0.02 per job and Video filter is $0.02 per job. Video filter docs describe dim and crop operations on one Sume-hosted clip returning a new MP4, with a source up to 300 seconds and an unbilled check endpoint (POST /v1/video-filter/check). A crop is not a content-aware reframe, so it will cut the frame rather than extend it.

• Trim a 20-second clip to the 3-second fix window: $0.02.
• Crop it to a new aspect ratio: $0.02.
• Regenerate the fix on a listed model, for example 3 seconds of gemini-omni-flash-1.1 at 1080p: 3 x $0.1875 = $0.5625.

Takeaway

If you only need cut-down or crop, the fixed fee wins by a wide margin. If you need new pixels outside the original frame, only a generative reframe does that, and Sume has no equivalent in its catalog.

Retake against regenerate

The 2.3 Pro text-to-video price on the same page is $0.08 per second at 1080p. Regenerating a whole 8-second clip therefore costs 8 x $0.08 = $0.64, which is less than the $0.80 a Retake of that clip costs. The Retake is more expensive because you pay for the entire input second by second, even though only a part changes.

So Retake pays off only when you must keep the rest of the shot exactly as it is. If you can accept a new take, regenerate. If you want to keep the take and change a short segment, cut the segment first and retake only that piece.
