Can’t import .mts files from my Sony camera to Premiere Pro CS5 and I keep getting the error “The file has an unsupported compression type”. How can I open .mts files in Premiere CS?

If you try to import these MTS files to Adobe Premier Pro, you may run into incompatibility issue. This is because that your MTS files contain come codecs or the resolution is not recognizable by Adobe Premiere. So what to do? The easiest and quickest solution is using a video converter to turn it into a compatible format for Adobe Premier Pro.

To do this work, I strongly recommend Video Converter Assist, which renders native codecs ensuring the best results when using Adobe Premiere.

How to Convert MTS to Adobe Premiere Pro?

1. Run the Video Converter Assist program and click the “Add File” button to import the MTS videos to be converted. The converter supports converting multiple files at a time.
2. Select the “Video” mode, and then click “Format” drop-down bar to select a proper video format such as MPEG-1/2 Video Files (*.mpg), AVI or MOV. The best method to avoid any problems and save time is to convert MTS footage into a Premiere Pro most compatible format like MPEG-2.
3. Click on “Convert Now!” button on bottom of the main windows and the conversion from MTS to Adobe Premiere Pro will begin immediately. When all conversions finished, you can run Premiere Pro and load the converted files to it. Then you would be able to edit MTS files in Adobe Premiere Pro with no obstacle.
