8-bit → 10-bit ProRes 422 HQ. 10-bit → 12-bit ProRes 4444. Keep your source color encoding, frame rate and audio.
Intro
Frustrated by the limited grading latitude of 8-bit footage, we tested different approaches across hundreds of minutes of footage. Our AI estimates intermediate tonal values for smoother transitions in higher-bit-depth ProRes. Results vary. This will not recover lost detail or clipped highlights, or add captured dynamic range.
Find where the banding first appears
Color banding looks like visible steps across an area that should change smoothly. A blue sky, a softly lit wall or a shadow fading into darkness can make it especially noticeable. Before enhancing the clip, compare the original, the graded timeline and your exported file to identify where those steps first become visible.
If the original looks smooth and only a delivery export or online upload shows bands, check that stage first. Another export setting may be more useful than processing the source. If the steps are already visible in the footage or become objectionable under the grade you need, a short enhancement preview gives you a practical comparison.
RGBA offers higher-precision ProRes output for supported clips: 8-bit footage can become 10-bit ProRes 422 HQ, and supported 10-bit footage can become 12-bit ProRes 4444. Results vary with the source. Severe compression, missing detail and clipped highlights are limitations; complete removal of every band is not guaranteed.
Evaluate the result fairly
- Choose a section with both the affected gradient and nearby fine detail.
- Apply the same grade to the original and enhanced clip.
- Watch the full moving shot; a smooth still frame alone is not enough.
- Check your final export on the intended display and delivery platform.
Will enhancement fix banding that appears only after upload?
Not necessarily. A delivery service can introduce new artifacts when it compresses a clean master. Compare the local master with the uploaded version first. A higher-precision source does not guarantee that every downstream encode or display will show smooth gradients.
Why can banding become more visible after denoising?
Noise can hide tonal steps in a gradient. Removing it can reveal those steps, and a later compressed export can introduce more. A cleaner image is not necessarily a smoother gradient. Compare the bands separately from the noise, then check the result under your intended grade and in your final export.

What to look for in the banding comparisons
The Candle glow and Last sparks sunset examples below use cropped views enlarged 2× for inspection. Each original and enhanced pair has the same example grade. These stills show specific regions; test motion and fine detail in your own clip before processing the full shot.
Candle glow: inspect the falloff beside the flame
The stepped glow beside the flame becomes smoother in the enhanced crop. Some broader bands remain in the dark background. Look at the transition around the light, rather than using the bright center as evidence of recovered highlight detail.
Last sparks sunset: separate texture from tonal steps
The enhanced orange sky has smoother fine texture under the same grade. Tonal steps and compression artifacts remain, so this example is not proof of complete banding removal. Compare the sky and cloud boundaries as well as the quieter texture.

Before you upload
Who is RGBA AI Video Enhancer for?
Filmmakers and editors preparing existing footage for a color grade. If lifting shadows or adjusting color makes noise or tonal steps distracting, compare a short enhanced clip under the same look. Judge the result by the shot you need to deliver, including texture and motion.
Does RGBA replace DaVinci Resolve or Premiere Pro?
RGBA enhances supported source clips for your editing and grading workflow. Continue editing and applying your look in your grading software after enhancement. The current web enhancer does not automatically grade footage or match shots; test its ProRes output in your own workflow before processing more clips.
Which files are supported?
ProRes, H.264, H.265 or MPEG-2 in MOV, MP4 or MXF; also FFV1 MKV. Progressive, constant frame rate only. Up to 4K / 60 fps, 12 GiB and 10 minutes. RAW is unsupported. RGB, interlaced and variable-frame-rate files need conversion first.
Which upgrade should I choose?
After upload, we detect resolution, bit depth and color sampling (such as 4:2:0 or 4:2:2). Upgrade color depth at the original size, or choose 2× width and height with higher bit depth when the result fits within 4K. For example, 1920 × 1080 8-bit footage can become 3840 × 2160 10-bit ProRes. Native 12-bit footage keeps its bit depth when upscaled.
What should I expect?
Expect smoother gradients, cleaner shadows and finer color precision under your grade. Results depend on the source; enhancement does not add newly captured dynamic range or recover clipped highlights. Check your intended grade, motion and fine detail in the free preview.
Can I enhance AI-generated video?
Yes, supported Rec.709 SDR exports can use the same upgrades. An 8-bit 4:2:0 MP4 can be enhanced to 10-bit 4:2:2 ProRes; a supported 10-bit file can become 12-bit ProRes. Choose higher precision at the original size, or 2× resolution when the output fits within 4K. Generator settings vary, so we inspect the actual file. See AI Videos (Rec709) in the compatibility tabs.
How do I use the output?
Keep your source color settings, whether Rec.709 or log. Video-range ProRes; no alpha. Final Cut Pro compatibility is unverified—test your free clip first.
Can I leave after uploading?
Yes. Processing continues after upload. Resume interrupted uploads within 24 hours using the same file.
How long are files kept?
Private downloads last 30 days; permanent deletion may follow later. Incomplete uploads expire after one day. Keep your originals.
