![]() Resulting clip after heavy noise removal and exporting using a lossy codec H264 main profile with a high bitrate at maximum depthĬlose-up of banding present in resulting lossy H264 codec export. Original clip, Neat Video’s noise reduction plug-in in progress. Original clip, close-up of noise present in background. Original clip displaying minor noise in background. We’ll begin by fully denoising this video using Neat Video. The frame below shows the footage we’re going to be working with as you can see, the image has some minor noise in the areas with uniform colour. To demonstrate how banding can be introduced into your video, we’re going to apply a series of techniques to the same piece of footage, experimenting with full and partial noise reduction with both intermediate and final codecs (in this case ProRes 422 and H.264 main profile) to see what delivers better results. Our particular test example will be reviewed based on the second stage: on exported clips played via a media player (in this case VLC). Ultimately, it is advisable to take proper precautions prior to export to minimize any unnecessary banding where possible in later stages of the process. Banding may not even appear present until uploading the final export to a streaming service such as YouTube which further compresses your export, which would suggest using a platform that applies a higher quality video compression such as Vimeo. The same applies to the final stage: an external resource such as a streaming service. If banding occurs in a specific player such as QuickTime, which is prone to inaccurate reproduction of fine gradients, it would be advisable to switch to a higher quality player such as VLC player. In some cases, you may successfully reduce banding in export but still encounter it in a media player. This then takes us to the second stage, viewing a clip in a player such as QuickTime. It’s worth noting that if the workflow requires exchanging intermediate video files with colleagues, it is advisable to use an intermediate codec instead of a final codec. If you encounter banding when previewing your footage in your video editing software, you’ll need to take various precautions during the post-production process and potentially apply the techniques discussed later in this article. ![]()
