I have Sony HDR-CX700V camcorder, which owns "Exmor R" CMOS sensor and delivers superior low-light capabilities. It records 1920 x 1080 Full High Definition quality video in AVCHD format. And I find there is not tool like Tsmuxer for merging AVCHD MTS files without recoding on Mac. I go to forum often and find a free, simple tool - MTSMerger_Mac_1_0_0_0.zip, after installed it on Mac, launch it, and import the 4 MTS files into the program, it can merge the files, but the speed is very slow, and the output file is very choppy for playing with VLC.
So how do I merge these Sony HDR-CX700V MTS files into one big file without recoding or conversion on Mac? When I was looking for Mac Sony MTS Joiner without Recoding, I found Aunsoft Final Mate for Mac, which is focus on merging camcorder MTS videos without conversion, I just downloaded and tried the program. Excitedly I have joined these Sony HDR-CX700V mts files at super fast speed. And it really didn’t require the re-encoding of the files and did not destroy the video quality.
Here is my experience with Aunsoft Final Mate for Mac to merge/stitch the Sony HDR-CX700V mts files on Mac, some simple instructions:
Step 1. Capture mts videos from camcorder.
Run Aunsoft Final Mate for Mac as a Mac smart mts joiner without conversion, connect Sony HDR-CX700V camcorder to PC via USB cable. You will face the pop-up message asking you to use camcorder wizard or not. Click Yes, you will face the window to choose Backup or Import, just select import and the files will be displayed in Camcorder Tab.
Step 2. Merge/stitch Sony CX700V MTS files into one with no conversion on Mac.
Click the drop-down button for the Add movie icon and choose lossless output, drag and drop the clips from the Camcorder tab to the movie ID, and the files with the same parameters like frame size, audio channel will be joined to the movie. Or you can directly drag and drop clips to Timeline using Ctrl + A for directly merge all the MTS files.
Step 3. Export the big MTS file without any decoding/encoding.
Click the Export button. As there is no video for conversion, just click the OK button for export without any decoding/encoding on Mac OS X.
The lossless output will be finished in only a few seconds or minutes. Try it yourself for the fastest and keep intact quality for Sony CX700V mts stitching on Mac.
