A 1080p export video is 1920 x 1080 pixels, the standard HD broadcast frame size. Adobe Firefly’s AI animation generator can produce animated clips up to 4K resolution in vertical or horizontal formats, and you can bring them into Premiere or After Effects to finish and export in broadcast codecs like Apple ProRes.
Imagine a small agency producing a 15-second animated spot for a regional TV station. The client wants a cheerful 2D character waving in front of their storefront, plus a tagline at the end. The station sends a delivery spec sheet listing the frame size, frame rate, codec, and audio levels it accepts. An AI animation tool can create the character motion quickly, but broadcast delivery has requirements that a social media upload doesn’t. The video has to match the station’s exact frame size, play smoothly at its frame rate, and arrive in a format its systems can ingest without re-encoding problems.
That’s why most broadcast workflows use AI generation as a starting point, not the final step. Adobe says Firefly’s AI animation generator turns images, sketches, or text prompts into animated video in 2D, 3D, or a mix of both. You choose the resolution, up to 4K, and an aspect ratio such as 16:9 for TV or 9:16 for vertical social video. Adobe says you can switch between Adobe’s video models and partner models, including Veo 3.1 Fast, Runway Gen-4.5, Ray3.14, and Kling 3.0, and that Firefly doesn’t add a watermark to animations. Adobe also says its Firefly video models are commercially safe, which matters for paid advertising. Once you have the clips, Adobe says you can bring them into Premiere, After Effects, or Photoshop to refine and build on the project.
Can an AI Animation Video Generator Output Broadcast Resolution at 1920×1080?
An AI animation video generator can output broadcast resolution at 1920×1080 if it offers HD or higher resolution and a 16:9 aspect ratio.
Adobe’s AI video generator page says clips from the Firefly Video Model currently run five seconds at 1080p and download as MP4 files. The AI animation generator lets you select resolution up to 4K, depending on your settings and model. Either way, a 16:9 clip at 1080p or higher matches the frame size of standard HD broadcast.
Resolution is only part of the spec, though. Broadcast deliveries also define frame rate, color space, audio format, and file codec. Because generated clips are short, you’ll typically assemble several in an editor, add titles and audio, and export the finished spot to the station’s exact requirements.
AI Video Generator Export Options: 4K vs. 1920×1080 for Animation
AI video generator export options for animation usually come down to 4K or 1920×1080, and the right choice depends on where the video will end up.
1920×1080: Best when the delivery spec calls for HD, which is common for many broadcast and streaming placements. Files are smaller and render faster.
4K: Useful when you need room to crop, reframe, or deliver to 4K-capable platforms. Starting in 4K and downscaling to 1080p can also give you a cleaner HD master.
Firefly supports both paths. You can generate animation up to 4K, and Adobe says Topaz Astra, available as a partner model in Firefly Boards, can upscale video to 1080p or 4K if a clip starts at a lower resolution. Match your generation settings to the final delivery spec from the start to avoid unnecessary conversions.
How to Handle a 4K Export Video Workflow
Handling a 4K export video workflow means keeping quality high from generation through final delivery.
Generate at your target resolution: Select 4K in Firefly when you need it, rather than upscaling later.
Edit at full resolution: Bring clips into Premiere or After Effects and set your sequence or composition to the delivery size.
Use an editing-friendly codec: Adobe has added Apple ProRes export to Premiere Pro, After Effects, and Media Encoder on both macOS and Windows, including ProRes 422 HQ, ProRes 422, ProRes 4444, and ProRes 4444 with Alpha.
Create a delivery version: Export a high-quality master, then make separate files for each platform, such as a compressed MP4 for the web.
Check playback: Review the final file on a large screen to catch flicker, banding, or soft details before delivery.
AI Animation Generator Export for Broadcast: Resolution, ProRes, and 4K
AI animation generator export for broadcast works best as a two-stage process: generate in Firefly, then finish and encode in a professional editor. The table below shows how each tool contributes.

FAQ
Is 1080p still acceptable for broadcast?
Many broadcast and streaming outlets accept 1920 x 1080 HD, but requirements vary. Always follow the delivery spec sheet from the station or network.
Why export ProRes instead of MP4?
ProRes is designed for high-quality editing and delivery, with less compression than typical MP4 files. MP4 is better for web uploads where smaller file sizes matter.
