Hello, I have an audio recording that I want to attach to a video file I edited in Vegas Pro 21. I do not want the audio file affected in any way, therefore, do not want to render it with the video file. How can I attach the audio and video files together?
Hi @IrishNachos, if Vegas cannot 'smart render' the audio to your existing file type (MP4 and such), a Muxing utility can embed an audio to the video file.. There are free muxers available. What is the video file's format?
AFAIK @IrishNachos, a PCM (wave) file cannot be muxed into a AVC/MP4 video. The audio must first be encoded to the AAC audio format which usually has a .mp4 or ,m4u extension. For muxing audio to AVC video, I have used MeGUI, Avidmux and MP4Box. For encoding an AAC file, Nero's AAC Encode or FFMPEG is allegedly the best.. but my old and abused ears cannot hear any difference in an A-B compassion using the native AAC audio encoders in Vegas and Sound Forge. If you are rendering the video, just put the PCM file on the timeline and forget about the encoding and muxing. If the video is already rendered, muxing in the audio is the way to go and does not re-render or re-encode either component.
