H264 Video Editor: Edit H264 Video Files Effortlessly

Step 1 - Add H.264 Video into the Program

Launch HD Video Converter Factory Pro and select the Converter module from the initial interface. Click +Add Files to import your h.264 videos, or simply drag and drop them into the software.

Step 2: Edit Videos with Provided Editing Features

After loading the videos into the converter, you will see a toolbar with video editing tools on it below each video. You can click on each icon or a combination to edit your H. 264 videos. Below are brief introductions to some editing features.

#1. H264 Video Trimmer

If you want to cut off unwanted video parts or split long videos into parts, you can press the scissor-shaped button to open the video cutting window. Here you can drag the two sliders on the timeline to select the desired segment or type in the exact start and end time to make it more accurate. Then press the green Trim button to create one clip, and click OK to go back.

#2. Flip/Rotate H264 Video

Press the circle-shaped icon, and you will see the video rotating window. You can flip videos horizontally and vertically and rotate videos 90 degrees clockwise or 90 degrees counter-clockwise, as the picture on the right shows. Then click on OK to save the changes.

#3. H264 Video Cropper

Enter the crop window by clicking the fourth icon on the toolbar. You can drag the dash-lined rectangle to choose your desired area under Free Aspect Ratio or select a specific ratio setting under the Fixed Aspect Ratio. Then press OK to return to the main interface.

#4. H.264 Video Merger

To merge videos, you need to add at least two video files to the program. Then hit the Merge button on the top menu bar. Then select the videos you want to merge and click the middle Merge button to create Pack 1. Finally, press the bottom Merge button to add them to the task list.

Step 3: Select the Output Format

If the displayed format icon on the right side of the interface isn't your desired one, you can press it to enter the output format library, and then select H.264 under the Video tab. As mentioned above, you can also choose H.265 for MP4 to shrink your file size while preserving the original quality.

Step 4: Output Edited Video File

Hit the inverted triangle button at the bottom to specify an output path. Then press Run to export the edited video. With hardware acceleration supported, the process will be finished at a super-fast speed.
