Although Avid claimed that Media Composer offers native AVCHD support, there are still some video, audio codec problems while importing/editing AVCHD MTS clips in Avid. Plus, even the Media Composer can ingest your MTS files directly, it takes a long time for rendering. Then, how to get Avid working perfectly with AVCHD MTS footage? A best way is to transcode MTS to DNxHD, something ensuring maximum editing quality and efficiency when working with Avid Media Composer.

In fact, MTS footage captured by Sony Handycam is quite different with those by Canon EOS 7D, and incompatibility exists among different camcorder manufacturers. H.264/AVC encoded MTS footage 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 are not so friendly for editing software. To avoid any problems, the best method is to convert MTS footage into Avid most compatible format - DNxHD.
