Many modern video cameras output in the avchd format, this creates MTS files that you need to import into Premiere Elements to edit together and work on as you desire. Although it is officially stated that MTS is supported by Premiere Elements, many MTS to Premiere Elements issues still exist there and troubled the users. In fact, there are some clues for users to check if they can not open MTS clips in Adobe Premiere Elements:

1. Start a new project

Try starting a Premiere Elements project and placing one of your AVCHD files at the beginning of your timeline. This will trigger Premiere Elements to automatically download the components for this type of video. Once it has this component, your computer should create the thumbnails for the files. It won't happen immediately - but the Organizer will work in the background to update itself as you do other things.

2. Download latest version of Quicktime, per the program's requirements

3. Adjust the project settings for PAL/NTSC

What if you still cannot ingest MTS files into Adobe Premiere Elements after all efforts?

On this occassion, a best way to avoid any problems and save time is to transcode MTS files to Premiere Elements more editing-friendly format. In fact, the incompatibility of AVCHD .mts files exists among different camcorder manufacturers. Mostly, the MTS footage captured by Sony Handycam is encoded with H.264/AVC codec which does not work well with video editing software except for few ones. Despite of this, H.264 codec is acknowledged as a universal codec for camcorder videos, especially for HD contents. The advanced compression method of H.264 results in much less storage and the same picture quality comparing with MPEG-4. However, the highly-compressed content is not so friendly for editing software.
