Is there any way to swap out the audio track on a rendered H.264 MPEG-4 without having to re-render the entire video project? Can this be done with Premiere, MPEG Streamclip, ffmpeg, or some other tool that I'm not familiar with ?
I have a long video project that took many hours to render, and I would like to swap out the audio (minor mixing changes) without having to re-render the entire video project. The new audio is exactly the same length.
Is this feasible? I'm primarily a Premiere user, but I'm happy to hear solutions for other tools.
