How to Convert MTS/M2TS to HEVC x265 with Virtually No Quality Loss

When it comes to compare H265 with H264, there is high likelihood that you would prefer H265 (HEVC) to H264, especially if you have an iOS 11 iPhone iPad or macOS High Sierra MacBook or iMac. That's because HEVC (H265) is superior to H264 in various aspects, e.g., same high quality but 50% smaller than H264, faster streaming than H264 while consuming less bandwidth, support higher video resolution than H264, up to 8K 4320p, etc.

Given the above, most camcorder hobbyists choose to re-encode their H264 MTS/M2TS to HEVC MP4/MKV after they make use of their AVCHD camcorders (Sony, JVC, Panasonic, Canon) to record .mts and .m2ts HD videos. Thus, they can successfully play MTS/M2TS video on iPhone iPad, MacBook/iMac or Android devices with less space consumption and no video incompatibility problem.

With the converter here, you can easily convert MTS/M2TS videos to HEVC H265 with 98% quality reserved, no matter the input MTS/M2TS file encoded by H264, H262 or MPEG-2. The program we're talking about is the very world-class MacX Video Converter Pro.

How to Transcode and Convert MTS/M2TS to H265 at Minimal Quality Loss

Step 1: Launch this HEVC Video Converter
Run this H265 transcoder on your Mac or PC after you free download this MTS to HEVC converter on Mac or Windows.

Step 2: Add Your MTS or M2TS Video
Click "Videos" button and you can add your camcorder recorded .mts/.m2ts video files. Or just drag and drop mts/m2ts files into this H265 video converter.

Step 3: Choose HEVC MP4 or HEVC MKV Format
Select the output video format on the pop-up window. You can choose MP4 video (HEVC) from "Mac General Video" profile or MKV video (HEVC) from "PC General Video" category. You're suggested to choose "MP4 HEVC" as output format if you wanna play .mts or .m2ts video on iPhone X/8/7/6s/6/Plus and MacBook/iMac with macOS High Sierra, as well as play MTS/M2TS on Samsung Galaxy Note 8, Sony Xperia X, Huawei, Google Pixel, etc. devices. Because MP4 HEVC has better compatibility than MKV HEVC and it also supports up to 4K 2160 in HEVC codec.

Generally, the preset output profile keeps the same resolution, frame rate, aspec ratio and audio codec with the input h264 file settings. If you need to upscale 1080p to 4K 2160p or lower resolution from 4K to 1080p/720p, tap settings icon to customize your output H265 resolution, frame rate, etc.


Tips to improve output H265 quality:
1. On the output profile window, you can move the LQ-HQ slidebar to improve output video quality.
2. Mannually tick "Use High Quality Engine" and "Deinterlacing" to improve output H265 video quality. Of course, this is at the cost of slowdown your MTS to HEVC conversion speed, to some degree. After all, quality and speed are negatively related.

improve speed and quality

Tips to improve MTS/M2TS transcoding speed:
1. The high quality technologies and speed acceleration tech are placed in the same zone, right-lower corner of the interface. If your computer supports Intel Quick Sync Video hardware acceleration, then the option will be auto ticked. If not, resort to another computer with Intel QSV supported.

2. Where is multi-core CPU utility? Look at the top banner and click "Options", from which you can find "CPU Core Use" and freely select how many cores you wanna use to convert M2TS or MTS to x265 H265. Generally, the default setting is the maximum number.

3. Tap the mark icon next to "Auto Copy" and you will know what Auto Copy means. This is to 100% losslessly copy video audio file data from one container format to another new without decoding or re-encoding, like remux MTS H264 to MP4 H264, M2TS (H264) to iPhone X (H264). Because it's designed to remux and demux video from one to another container format, no the middle two steps (decode & encode). Its copy speed is world's fastest, 10X faster than others.

Step 4: Convert MTS/M2TS to HEVC Now
Hit "RUN" button and it will begin to decode MTS/M2TS and encode video to HEVC (H265) at Intel QSV hardware accelerated speed, along with mutli-core CPU (up to 8) and hyper-threading tech. The output HEVC video will automatically open after the MTS to h265 conversion is over. So you don't have to stare at the process. Just do your other things. And a few minutes later, come back to play HEVC on your macOS High Sierra or tranfer HEVC to iPhone iPad Android for playback.
