1
Prepare a representative sample
Keep the original file and trim a short segment that includes the hardest parts of your footage: movement, a face, fine patterns, captions, or a dark scene. Inspect the source at its native size first. If text is already unreadable or a face is heavily obscured, an upscaler cannot verify what was originally there. Note the source resolution and frame rate so you can compare the processed clip fairly.

Open the route and check its controls
Follow the SeedVR link, then read the destination's current instructions, accepted inputs, and any displayed limits. Supply the test clip only if that interface accepts your file type and size. If it offers an output scale or quality controls, start conservatively and change one option at a time. Do not assume a prompt box, a particular preset, or a specific export format exists; those details vary between implementations.
3
Compare, then decide whether to continue
View the source and SeedVR result at the same display size and inspect several moments, not just the best-looking frame. Check facial features, lettering, edges against the background, and textures while the camera moves. Watch for shimmer, repeated patterns, oversharpening, or a smooth-looking surface that has lost real detail. If the short test helps, apply the same reviewed approach to more footage; otherwise adjust your source preparation or settings.
