Q: “I tried dragging the AVCHD file directly into Premiere and keep getting an error message that says ‘File format not supported.’ I don't know why Premiere is all of a sudden giving me problems with AVCHD files. Any help is greatly appreciated!”

Though Adobe Premiere Pro claims to support AVCHD files, many users reported that they had trouble importing AVCHD into Premiere Pro for editing. The best way to fix it is to convert AVCHD to a more Premiere-friendly format like ProRes which is widely used for professional post-production.

Part 1. Does Premiere Pro Support AVCHD?

Yes. According to Adobe’s official website, Premiere Pro supports importing AVCHD files with .mts or .m2ts file extensions. But it is not the most compatible format for smooth editing in Premiere Pro. Instead, AVCHD, short for Advanced Video Coding High Definition, is great for digital recording and playback of high-definition video.

If you have a bunch of high-quality AVCHD footage created by Sony or Panasonic camcorders. To make sure you can import AVCHD to Premiere Pro with no obstacles, the best practice is to transcode AVCHD to a mostly-lossless format which, meanwhile, must work well with Premiere Pro too. The most common post codec choices are Apple’s ProRes, Avid’s DNxHD/HR, and GoPro’s Cineform codecs.

Part 2. How to Import AVCHD into Premiere Pro?

To make sure the quality of the footage file is preserved as much as possible, you can convert AVCHD to Apple’s ProRes, DNxHD/HR, or Cineform. Among them, Apple’s ProRes is strongly recommended. The format was created by Apple Inc. for high-quality and high-performance editing tasks. Converting AVCHD to ProRes is the best way to help preserve the original quality.
