I have a large collection of video clips, each with its corresponding audio clip that I want to merge. I need to automate the process by having each video clip merge with its respective audio clip, then have all the merged clips exported as mp4 file. How do I do this in Adobe Premiere Pro 2020?

1 Answer 1


What format are the seperate audio/video files? Are the audio files currently in sync with the video?

I did this recently with some old source files that had originally been authored for DVD, the source files were .m2v / .wav pairs of files. I used TMPEGEnc Smart Renderer to merge all the source files into one big .mpg file (no re-encoding in this step with that tool, so no quality change), and then fed the resulting file into Handbrake to get an MP4 file. For a one-off, you can likely just use the trial version of Smart Renderer.

For Premiere it would basically be the same, import all the source files, create a sequence, and then drag the video & audio files onto the sequence as appropriate, and export to H.264 Format. Smart Renderer worked easier for me, as the files were mostly prefixed with number order, and the video/audio files had matching names, so I could literally just import a folder at a time into the project, and not have to rearrange anything to get the correct pairing and sequencing - a bunch of the manual sequencing work got done for free by doing it this way. Premiere just would have taken longer to do the same job, plus not trusting myself not to make a mistake somewhere manually building the sequences.

  • the video files are in .TS format while the audio are WAV files, each video file is separate from its corresponding audio file.

  • If the source files are in pairs with the same filename, just different extensions, you should be able to process them through Smart Renderer as suggested - it will pick up the correct audio file from the name when you add the video file. NOTE this usually works when the video file is "video only", i.e. .m2v, I've not ever seen a .ts (transport stream) file that doesn't contain audio as well, so I'm not 100% sure with your files - more info on their source and what they contain would be useful. Otherwise, dragging everything into Premiere should also work, but it will re-render as well. Commented Dec 4, 2020 at 10:50
