Other tools include a real estate video maker, social video creator, compressor, AI image generator, 4K AI video generator, and enhancement API. The real estate workflow converts listing photos into videos in 10 minutes. Supported inputs include MP4, MOV, AVI, MXF, and MKV containers, with codecs such as H264, H265, Apple ProRes, DNxHD, VP9, and AV1. Enhanced video output uses H264 or H265 in MOV, MP4, or MKV.
