Comparison of rate-distortion performance (BD-rate) and computational complexity (kMACs/pixel, parameter size and inference time) for sequential and channel temporal concatenation implemented with ATEM-Hybrid CA and ATEM-Swin. BD-rate values are calculated on the UVG data set relative to the VCT baseline. Encoding and decoding time are per-frame speed, evaluated on 1080p videos with one RTX3090 GPU
