[size=xx-small][font=Tahoma, sans-serif][size=medium][size=x-large][size=small][size=medium]I have been making successful .mp4 movies with LRT3 / 4 for over a year. Recently I tried to render movies using the Prores and 4K settings, which output in .mov. I cannot play these movies on any of my computers, but I can play any other .mov movies of similar file size which are not rendered by LRT.  All of my mp4 movies rendered by LRT play fine. I have tried producing at 1080 and have the same problem; each time I get the error message  “Windows Media Player encountered a problem while playing the file”.[/size][/size][/size][/size][/font][/size]

Those are Prores files. Use MPC player on windows, to play them: http://mpc-hc.org

Thank you for the rapid reply;  that worked!
