Tips & Tricks for Editing MTS Files in Premiere Pro Smoothly

"Hello, I was wondering if anyone using Premiere Pro 2020 had experienced issues with .mts files. I've been trying to create a video with footage all from .mts files, but they are causing me a plethora of problems."
"After a minute or so of editing .MTS footage from a Sony camera, the preview goes black but I can still play and hear the audio from the footage. I can edit .MP4, .MOV, and everything else fine except for .MTS. Is there a setting I can change to fix this problem editing .mts footage in CC 2019?"

As a timeline-based video editing software application, Adobe Premiere Pro comes with ability to stabilize shaky clips exported from your Sony/Panasonic camcorder or video camera. Although Adobe claimed that Premiere Pro CS5 and above offer much better native AVCHD support than it predecessor. the users who want to edit MTS videos with Premiere Pro usually run into incompatibility issues. Or you can't edit them smoothly after taking some time for importing MTS to Adobe Premiere. Why? This is due to that MTS videos, which are already highly compressed by H.264 codec (also known as long-GOP compression), are very hard to deal with during video editing.

To edit MTS footage in Premiere Pro smoothly, the easiest and most efficient solution is to transcode MTS to Adobe Premiere edit-friendly codecs. And Apple ProRes is the best choice for smooth editing since the codec sits in a kind of "sweet spot" between the humongous data rates of uncompressed video, and the egregious processing demands of Long Gop MTS video. Once you've converted, your MTS edits in Premiere Pro will fly.

Kindly Note: Apple ProRes codec doesn't compress the video as much. They trade storage space and bitrate for quality and ease of processing. But the converted ProRes file typically need ten times as much storage. That's a lot, but hard drives are tending towards being free, so it hardly matters these days.

Final Words:

If you're having trouble editing MTS files in Premiere Pro, Final Cut Pro, iMovie or Avid Media Composer, transcoding MTS to ProRes or DNxHD will be an efficient solution to quickly solve your problem. Both ProRes and DNxHD are effectively "visually lossless" at their higher bitrates. That means exactly what it says: you can't tell the difference between your original video and the same material encoded to ProRes or DNxHD. And EaseFab Video Converter is a highly-recommended program to help you get the encoding job done fast and losslessly.

Once you've converted, your edits will fly. These codecs are so efficient that you can play multiple streams with a fraction of the effort you need for a single stream of H.264 - based video. As an example, on my Macbook Air, playing any HD Long-Gop MTS clip will cause the fan to come on at full power within seconds, but with ProRes, I can play a clip - in much higher quality - with no sign of the fan.
