How to Deinterlace 1080i MTS Files on Mac

Published on by Chris King

Have some 1080i MTS files and want to deinterlace MTS videos to get real Full HD videos? This article teaches you how to remove interlace from 1080i MTS footage easily.

I have a Sony HDR-CX305 for years. It claimed that it can record "Full HD" video. The format has been dubbed "AVCHD" by Sony and the videos are stored in .MTS. What I, very unfortunately, did not recognize when buying the camera is that the "Full HD" that the camera promises is not real Full HD. Near the end of the "technical data" page is the following text:

Video Quality: HD; FX (1920 x 1080i, 24 Mb/s)/FH (1920 x 1080i, 16 Mb/s)/HQ (9 Mb/s)/LP (5 Mb/s), SD; HQ (9 Mb/s)

And I realized that the camcorder only has a horizontal resolution of 1440 pixels, not 1920. To overcome that limitation, the camera defines a pixel to be rectangular and not quadratic. Now if we combine the information with what we know after trying out:


So, 1440 x 540 it is. That's supposed to be Full HD? It's less than half of the real Full HD resolution (1080p50)! In the end I had to deinterlace MTS videos all I have.

First of all, I tried Handbrake. It also sucked very much; their deinterlacing modes were equally bad (yep, I tried them all).

After I had given up and was putting up with HandBrake's bad deinterlacing, I finally found the solution- Brorsoft MTS Converter for Mac, which gives me awesome smooth deinterlaced videos.

It can help you to remove the interlacing artifacts of the camcorder videos. The output video plays smoothly without any sluggish problem. What’ s more, it also supports converting MTS, M2TS videos to any format you want including MOV, MP4, AVI, WMV, MPG, etc common files or ProRes, DNxHD, Apple InterMediate Codec, HDV, etc professional encoders for FCP, Avid MC, iMovie, FCE and more NLEs.

Below is how to deinterlace and convert AVCHD camera video:

Step 1. Load MTS/M2TS

Run the program and click the Add button to load the .mts, .m2ts videos. The 1080i videos are quickly loaded to the program.


Step 2. Choose output format

You can just click the Format option and move the mouse cursor to HD Video, and there are several profiles for selection, e.g. H.264 HD video with .mp4 output and H.264. HD video with .mov output format. If you want to edit MTS in FCP, iMovie or editing programs later, you can choose a certain format like ProRes for FCP.


Step 3. Deinterlace 1080i MTS video

Click the Effect and then you will go to the Video Editor. Choose the Effect to see whether the “Deinterlace” has been chosen. If not, select it and it will help you deinterlace your 1080/60i MTS/M2TS. Usually, the program processes the deinterlacing video option by default.


Step 4. Start to convert and deinterlace AVCHD

At last, click the convert button to deinterlace AVCHD MTS/M2TS videos and remove the interlacing artifacts. After the conversion, you can the get the awesome smooth deinterlaced videos as you want.
