Hi Shadow: My questions was less about my knowing what you're asking After Effects and Media Encoder to do, but more about if you know what you're asking it to do. Part of building that awareness is benchmarking your system based on how you use it. High resolution source footage, like 8K images, should take longer than 4K or 2K images for AE or Media Encoder to process. Part of the reason H264 takes so long to encode is that the file size is really small with very good picture quality and it compresses between the frames as well as within the frame. While export format will affect system performance, one usually picks the export format based on what's required for delivery. If you're publishing to social media, H264 is the way to go right now. If you were generating an edited master for broadcast TV, you'd export a file at broadcast settings (probably an MOV, MXF or MPEG). If you were generating a file for DVD-Video authoring, you'd export a NTSC MPEG2 stream or PAL MPEG2 stream. If you were generating Windows Media files, you'd export to WMV. If you were a video DJ, you might encode to the HAP codec. I'm pretty sure you're getting the idea. There are some good articles on optimizing your AE system. Have you had a chance to read any of them? -Warren
