AnimateDiff vs Merge

AnimateDiff is a free, open-source module that turns many community text-to-image models into animation generators without additional training. Its main branch targets Stable Diffusion 1.5, with a separate branch for Stable Diffusion XL. MotionLoRA adapts motion modules for patterns such as zooming and rolling, while SparseCtrl uses sparse RGB images or sketches to guide animation content. The project runs locally: install dependencies with pip and run its animation scripts, which save generated samples in a samples folder. A local Gradio demo runs at localhost:7860 by default. The project points to official Diffusers support and community integrations for Stable Diffusion WebUI and ComfyUI; scripts handle checkpoint downloads automatically. For SDXL beta inference, the project notes a typical need of about 13 GB of VRAM, depending on the model and settings. It lists small flicker and limited general text-to-video quality as limitations, and suggests using images from the same community model for closer style alignment. The repository lists an Apache-2.0 license and says the project is released for academic use.

Merge is an iOS app that turns a still photo and a reference motion video into an AI-generated motion video, with an optional style prompt. The site says generation takes under a minute. Listed creation types include AI dance videos, animated portraits, moving selfies and cinematic motion; output can reach 1080p. Users can save videos to their device or publish them to a community feed where people can browse and like them. Merge is listed for iPhone only and uses Apple Sign-In; Apple handles billing. Its free Starter plan includes 300 credits per month, Full HD videos and community feed access. Creator bills 1,000 credits per month and adds a priority generation queue, while Studio bills 3,000 credits per month and adds a top-priority queue. Selected photos are uploaded to temporary storage for generation and automatically deleted within about 48 hours. Merge lists English, Spanish, German, Dutch, Turkish and Russian.
