OpenArt Director creates cinematic AI videos up to 5 minutes long just by chatting, keeping characters, scenes, voice, and style consistent.
Key features
Chat-Based Direction: Generate full videos by describing them in conversation; Director interprets mood, movement, and cinematic feel without a technical breakdown.
Long-Form Consistency: Produces seamless videos up to 5 minutes with consistent characters, scenes, voice, music, and visual style.
Integrated Audio: Adds matching voice and music so finished videos need no separate clip assembly.
Credit-Based Generation: Every render draws from a monthly credit pool shared across images, upscales, and video, with cost varying by model and quality.
Part of OpenArt Studio: Sits inside OpenArt's broader image-and-video creator platform with access to multiple models.
Best for
Short Film Creation: Turning a written concept into a multi-minute cinematic video without a production crew.
Marketing Videos: Producing branded promotional clips through chat instead of manual editing.
Social Content: Generating consistent, character-driven stories for social media.
Storyboarding: Quickly visualizing scenes and continuity for animation projects.
All-in-one AI-powered code editor for CUDA with hardware-aware agents, GPU emulation/virtualization, real-time profiling and enterprise benchmarking.
Key features
Agentic Hardware-Aware Assistant: An AI agent that reasons about NVIDIA GPU architecture (memory hierarchy, warp scheduling, occupancy) to suggest kernel-level optimizations, launch configuration changes, and micro-architectural fixes tailored to the target GPU.
GPU Emulation and CPU Simulation Mode: Built-in GPU emulator allowing developers to run and test CUDA code on machines without physical GPUs by simulating GPU behavior and validating kernel logic before deployment.
GPU Virtualization Support: Virtualized GPU environments for remote testing and multi-tenant workflows, enabling developers to run GPU workloads in isolated virtual GPUs for reproducible experiments.
Real-time Profiling with Smart Terminal: Live profiling integrated into the editor that surfaces hotspots, stalls, memory transfers, and kernel timelines in the terminal while code runs, allowing rapid iterative tuning.
Line-by-Line Performance Analysis: Fine-grained cost annotations that attribute runtime and memory behavior to specific lines or blocks of CUDA code to pinpoint bottlenecks and inefficient constructs.
Benchmarking Terminal with Sweep Configurations: Enterprise-grade benchmarking tooling that runs parameter sweeps (grid/search) across kernel launch parameters, inputs, and device targets and produces reproducible reports.
Open-source CLI and Easy Install: Community-facing CLI (rightnow-cli) available via pip for quick setup, enabling a lightweight GPU-native AI code assistant and integration into developer workflows and CI.
GPU Profiler Visualization: Web-based visualization transforms NVIDIA profiling data into timeline views, flame graphs, heatmaps and includes AI-powered bottleneck detection to accelerate root-cause analysis.
