    Food stills: Vidu for steam and pour, Seedance if the plate must hold

    Split diegetic sound vs identity.

    Split diegetic sound vs identity.

    A food still that becomes a clip is not "run the video model." Steam and pour are diegetic: hiss, glug, the beat the feed came for. The plate is identity: garnish, sauce edge, the dish on the menu. Vidu Q3 Image to Video writes a mix with the picture. Seedance 2.5 Image to Video holds a still through a longer pass. One row will not honestly own both.

    The hiss has to be born with the picture

    Vidu Q3 I2V requires an image. Audio is on. Durations are only 5, 10, or 15 seconds. Ceiling 1080p (360p / 540p / 720p / 1080p listed). Sixteen credits is the catalog figure; the row is discounted. No aspect-ratio menu — crop the still first.

    Write the pour: steam off the bowl, a quiet pass, no music if the hiss is the mix. Native audio means a silent prompt still gets a band. A 5-second take is the shortest clip on this slug. There is no 3-second cheaper retry. If the pour fails, fix the still or run another 5.

    High fidelity in the feature list is a plate claim. Q3 will not find a tasting-menu dish in a paragraph. If the garnish is already wrong in the jpeg, every second of steam is waste. Atmosphere and Foley here. Mouths elsewhere. Vidu Q3 native-audio product stories is the prompting habit: name two or three sounds, state "no music, no speech" for clean foley.

    Garnish drift is a failed SKU

    Seedance 2.5 I2V animates a locked still into a continuous clip at up to 720p, four to thirty seconds, native audio, optional last frame. Image required. Forty-seven credits listed. Features: first frame, last frame, long form, audio sync. The published family page is Seedance 2.5.

    The job is the plate the diner will recognise: sear, herb, rim. Thirty seconds in one pass is how you do not stitch three Vidu 5-second clips and watch the micro-green travel at the cut. 720p is Seedance's ceiling on this endpoint. 1080p steam plates are Vidu's. Resolution is delivery. The garnish is the I2V choice.

    Do not text-to-video "our signature pasta, exact plating." Make the still. Lock the still before you spend on motion. If you would not print the jpeg on a menu, do not buy seconds.

    Last frame only when the destination is a second approved still — lid on to lid off, raw to seared. Do not attach a last frame of a different dish to "show the interior."

    Crop, then pick the row

    • The ad is the hiss. Crop 9:16 or 16:9 on a still you would plate. Vidu Q3 at 5s. Write steam and pour. Do not start at 15s 1080p because the row is discounted.
    • The ad is the branded plate. Seedance I2V for the length you will actually ship.
    • You need both. Two generates. Hold identity on Seedance. Get the pour on Vidu. Stitch.

    A kitchen that reuses last week's row on every SKU will either scramble the garnish or ship a beautiful silent dish.

    Pause the take. Read the herb, the sauce edge, the bowl. Fail a menu audit: throw the clip away. Make a new still. Do not "fix" plating with text-to-video.

    Play it muted. If the pour looks like it should hiss, and then it does, you used Vidu correctly. If a cloned host is talking while the plate is frozen, you used speech as a substitute for physics.

    FAQ

    Can Vidu Q3 hold my plating if the still is sharp?

    It can try. The still is the contract, and Q3's job here is 5 / 10 / 15s motion with native audio at up to 1080p. If a drifted garnish over 15–30 seconds is the failure you cannot live with, use Seedance I2V.

    Can Seedance invent the pour if I write it in the prompt?

    It has native audio, so specify the mix. It is still the identity row. If the hiss is the product and the plate is already locked in the photograph, Vidu's 5-second diegetic take is the cheaper honest test.

    Why not one 15-second Vidu clip for everything?

    Fifteen seconds is triple the shortest Q3 take, with a soundtrack attached. Discounted is not free. Prove the pour at 5s. Prove the garnish on the identity row.

    Do I need a last frame for a lid lift?

    Only when the open plate is a second approved still. A single hero still with a small camera move and a breath of steam is the usual Seedance job. Vidu Q3 on this slug does not advertise a last-frame contract the way Seedance I2V does.
