The innovative combination of multimedia technology and non-legacy can enrich the expression of non-legacy and let traditional culture show new vitality. This paper selects, combines, and weights the evaluation indexes for non-heritage cultural creation and rural revitalization in the multimedia environment. We use the cloud model to measure the development level of non-heritage cultural creation and rural revitalization in a region from 2018 to 2023. We construct the regression model of non-heritage cultural and creative design and rural revitalization on this basis, applying the multiple linear regression method to determine the contribution of non-heritage cultural and creative design to rural revitalization and to investigate their role in promoting it. The results for non-heritage cultural and creative design and rural revitalization measures in the sample area are 0.301 and 0.331 respectively, reflecting uneven regional development. For every 1% increase in non-heritage cultural and creative design, the development level of rural revitalization increases by 0.316%. Notably, the derivative products of non-heritage cultural and creative design significantly contribute to rural revitalization, with a contribution of 0.315. Facilitating the transformation of non-heritage cultural and creative products into cultural and tourism products, establishing a mechanism for the incorporation of non-heritage cultural and creative design, and innovating non-heritage cultural and creative brands can promote further development of rural revitalization.
