When an AI video's colors do not match the image you started from, the main cause is that an image-to-video model does not copy your image into the clip: it paints every frame anew and uses your image as a guide. Two smaller causes sit on top of that: video stores color differently from a PNG, and you may be comparing a preview with an original. 8frame itself does not alter the colors of a generated video: the file you download is the file the model returned.
TL;DR
- The model repaints every frame. The start image guides it; it does not lock the palette, and drift can grow over a longer clip.
- Video stores color differently from an image. A PNG is full RGB; video is converted to a brightness-plus-color format with fewer color samples, and two players can display it differently.
- Compare like with like. Board previews are smaller WebP copies; download "Original" before judging the image.
- 8frame does not re-encode video. Any shift is in the model's output or in your player or editor.
- To keep a palette, use shorter clips, name the colors in the prompt, and give the model an end frame where the model takes one.
1. The model repaints every frame
An image-to-video model reads your start image, then generates each frame of motion itself. Light, color temperature and saturation are part of what it generates, so they can move away from the start image, especially as the camera moves or the clip gets longer. Models differ in how closely they stay to the start image, and we have not measured that, so test with your own image before you commit to a model.
Fix:
- Say the palette in the prompt. "Warm golden light, muted teal shadows" gives the model the same instruction your image gives implicitly.
- Keep clips short. Two 5-second clips give drift less time than one 10-second clip.
- Use an end frame where a model takes one. On the canvas that is Kling 2.5 Turbo Pro, Kling 2.1 Pro, Kling O1 Image and Kling O3, Veo 3.1 (8-second clips), and Seedance (with a start image). A last frame in the same palette gives the model a second anchor. See AI video with a first and last frame.
2. Video stores color differently from an image
Every image model we measured on 8frame returns PNG files, which store full RGB color for every pixel. Video does not. Microsoft's documentation of video formats explains that most YUV formats, the kind video uses, "contain fewer samples of U and V than of Y": brightness is kept for every pixel, color at a lower resolution. It also describes two different conversions between RGB and YUV, one for standard-definition video and one for higher resolutions, and two ranges for RGB (full 0 to 255, and studio video with black at 16 and white at 235).
What that means in practice: fine color detail is softer in video than in a PNG, and a player that decodes a file with a different conversion or range than it was encoded with shows colors that look shifted.
Fix: before blaming the model, play the downloaded file in a second player. If the colors change between players, the file is fine and the difference is in playback. If they match each other but not your image, it is the model (cause 1).
3. You are comparing a preview with an original
On a board, images are shown as smaller WebP copies (256, 640 or 1280 pixels wide) so pages load quickly. The download menu offers those as Small, Medium and Large, and the stored file as Original. A compressed preview next to a video frame is not a fair comparison.
Video works differently: 8frame does not re-encode it or make smaller copies, so the video you download is the model's file.
Fix: download the Original image and compare it with a frame from the downloaded video, side by side, in the same app.
4. A filter or your editor changed it
The Video Editor has filter presets (Retro, Vintage, Wes Anderson, Film Noir, Polaroid, Cinematic, Cool, Warm, Expired Film, Kodak, Super 8) and a brightness slider per clip. A preset applied to one clip and not the next is an easy way to get a color jump at a cut. The editor has no curves, color wheels or LUTs.
Fix: check which clips carry a filter, and apply the same one to every clip in a sequence. For exact matching between shots, grade in an editor with color tools.
FAQ
Why does my AI video look different in color from my image? The model generates every frame itself and uses your image as a guide, so light and color can move, especially over longer clips. Name the palette in the prompt and keep clips short.
Does 8frame compress or change my video's colors? No. 8frame does not re-encode generated video; the download is the model's file. Image previews on a board are smaller WebP copies, so download Original to compare.
Why does the same video look different on my phone and laptop? Players and screens can decode and display the same file differently. If the colors change between players, the file is not the problem.
Can I fix the colors in 8frame? The Video Editor has filter presets and a brightness slider per clip. It has no curves or LUTs, so for precise grading use a dedicated editor.
