Join AVCHD clips together-Split/Cut AVCHD Clips retaining the Highest Quality on Mac
Alternative to tsMuxeR on snow leopard for joining/cutting AVCHD at best quality
Canon camcorders provide simple video editing with cutting and trimming, so that you can get rid of the content without any sense and keep storage for useful recordings. However, when I play the clip on the LCD screen, I find it uneasy to split/cut AVCHD files. Even though Canon Vixia HF R20 is equipped with 3.0" Touch Panel LCD, the onboard feature of cutting/trimming/dividing video on Canon camcorder would take a long time for preview.
When it comes to Mac computer, things go more complicated as the bundled software in CD is only for Windows. When I googled camcorder software on Mac, some people suggested tsMuxeR, but it does not work on my iMac with Snow Leopard. I find Aunsoft Final Mate for Mac, as the perfect Mac alternative to tsMuxeR on Snow Leopard for joining/cutting AVCHD at best quality.
The step-by-step guide below may answer the question about how to preserve the best possible quality for AVCHD files on Mac.
Step 1. Import/Capture AVCHD files to Aunsoft Final Mate for Mac.
When Aunsoft Final Mate for Mac is run, it can automatically detect and pop up a wizard for you to capture video from camcorder. The videos would be listed on the "Camcorder" tab. And for the AVCHD files copied on Mac, just go to the "Resource" tab, click the "Add file path" button for the STREAM folder.
Step 2. Combine/Join clips into a movie as single file
Select the .mts or .m2ts files, drag and drop to the timeline and the files would be joined in sequence as one lossless movie. Alternatively, you can click the "Create New Movie" button, then drag and drop short clips to the movie ID to join the clips.
Step 3. Split/Cut AVCHD Clips with frame accuracy.
You can play the movie and pause at the timepoint you would like to cut off, then click the Split button to cut the video from the current frame. To get the exact frame for splitting/cutting, you can use the "Previous Frame" button and the "Next Frame" button. The "Goto" button would also help you quickly locate the video.
Step 4. Export AVCHD movie retaining the original raw video quality.
Click the "Export" button, and then the OK button. The Mac AVCHD cutter will start join/cut AVCHD Clips in native format without any conversion.
Hope you enjoy the workflow above to join/split/cut AVCHD MTS/M2TS files on Mac Snow Leopard, and retaining/preserve the highest quality without recompressing. The lossless HD videos will be ready in a few seconds.
For users with PowerPC processor on iMac/MacBook, Aunsoft Video Converter for Mac would help you convert H.264 MOV files from DSLR cameras like Canon 7D, Nikon D3100, D7000 to Apple ProRes for FCP or AIC for iMovie/FCE at the best possible quality.
