Hello, I have recorded a video content via zoom and have an mp4 file which I have imported into premier pro. I filmed a seperate introduction and conclusion which I have edited onto ends of the episode. It is a video podcast and I wanted to export the file to be used on youtube. From the zoom filming my sequence settings are 25 frames per second and the frame size is 1280 x 780. I have exported in the H.264 format with match-source high bitrate, VBR 1 pass. I have tried lots of different types of exporting from changing the bitrate and every time I export the video it takes 28 hours and the final product has clear audio but the video is lagging. I have tried looking on this forum for solutions as well as youtube videos and everything that I have done has not made a difference. I am using a Macbook Air 2019.
