It's most likely that you want to edit AVCHD videos recorded by your high-definition camcorder, so you can keep or share your sweet memories with others. However, it's not easy to do this. Many common editing tools don't support AVCHD formats. Of course, there are some available for editing AVCHD, but quite expensive. Here, I'll strongly recommend the best AVCHD editor - Wondershare Filmora (originally Wondershare Video Editor), which has the advantage of powerful function, easy to use, and reasonable price. The following is the step-by-step guide to show you how to edit AVCHD files with the best AVCHD editing software.
Download, install and run this AVCHD editor. And then follow the guide here.
Step 1 Import AVCHD files to the User's album.
Click "Import" option to import AVCHD videos from your computer to the album of this AVCHD editing app. Also, you can directly drag AVCHD files from the computer to the User' album.
Note: If your AVCHD files are on your camcorder, you need to connect it to the computer, and then take the AVCHD videos off.
Step 2 Drag AVCHD files to the User's Timeline.
Drag one or several AVCHD files from your Album to the Timeline at bottom. Note that please don't cover one video to another unless you want to split it. To add multiple files better, you can drag the slide bar (next to Create button)to adjust the view size of the Timeline.
Step 3 Edit AVCHD files.
Select your wanted video clip on the Timeline and then right click it and then select Edit option, or directly double click on the media clip to open the editing panel, where you can rotate, crop video, and change video effect and speed in video bar, edit audio track in Audio bar.
If you want to trim video to the specified length, click the video clip, mouse over its left or right edge to show the "double arrow" indicator, and then drag it to any length you want.
To split a video clip, you need to select it by clicking, drag the top of the red Time Indicator to any position you want, and then click scissor button.
Note: This smart AVCHD Editor also allows you to join AVCHD files, add titles, transition effects and intro/credit etc. to your videos. Importantly, you can view all the real-time editing effect in the Preview window. If you are not satisfactory with the editing effect, just do it again.
Step 4 Share your videos.
When you've finished the AVCHD editing job, click the Export button to save the settings.
If you want to own a prefessional video editor, then you can use Filmora, but you require more functions than editor, like converter, downloader, recorder, then Wondershare UniConverter (originally Wondershare Video Converter Ultimate) would be a much better choice, it can not only edit your videos but also convert your videos to many other formats, download/record videos from YouTube and many other sites.
Convert video to 1000+ formats, like AVI, MKV, MOV, MP4, etc.
Edit, enhance & personalize your videos file before conversion.
Download/record videos from 10,000+ video sharing sites.
