Decide whether the source needs upscale or transcode
If the source is already 1920 × 1080 and simply fails to play on a device, the problem may be codec, bitrate, container, or profile rather than resolution. Re-encoding can solve compatibility without asking an AI model to recreate every frame. Use upscaling when the source dimensions are genuinely smaller or visible softness prevents a useful Full HD delivery.
Inspect the original file properties and watch it at native size. Note resolution, aspect ratio, frame rate, duration, audio, and obvious defects. This establishes a baseline for the enhanced master. Without that baseline, it is easy to celebrate a larger file that has the same blur, new halos, or altered motion.
- Source resolution is below the intended delivery
- Aspect ratio and orientation are known
- The highest-quality owned master is available
