Then you might consider compressing the H264 video to save space, or share and upload. This post gives you several effective ways to reduce H264 video size and keep high quality.

Method 1: Compress H264 Videos with Advanced Encoder (High Quality Preserved)

H264 is now an old video codec compared with H265 (HEVC) and VP9. Advanced video codecs can encode a video to a smaller size while maintaining high quality. So, if you don’t want to sacrifice the video quality, you can choose the two advanced video codecs to reduce the H264 video size. Here are the steps:

Step 1: Launch HD Video Converter Factory Pro and open the Converter window. Then, click the +Add Files button to import H264 videos or drag and drop them into the program directly.

Step 2: Click the format image on the right side of the interface to expand the output format list. Head to the Video tab and choose one format from H265 for MP4 (recommended), H265 for MKV, and VP9.

Step 3: Specify an output folder and hit the Run button to start the compression process.

Method 2: Compress H264 Videos by Modifying the Video Parameters.

Besides Method 1, you can also shrink the video size by modifying the video parameters. Video resolution, bitrate, and frame rate are the main parameters that will affect video size. The lower the resolution/bitrate/frame rate, the smaller the video size. But this way will inevitably compromise the video quality. So you’d better change the video resolution from a high-quality video, lower the bitrate on video at a higher bitrate, and alter the frame rate better to 23.97fps or higher to keep a decent quality. The tutorials are given below:

Step 1: Launch the H264 video compressor program and open the Converter window. Then, import H264 videos by clicking the +Add Files button. Or drag and drop them into the program directly.

Step 2: Unfold the right-side format list and choose one output video format. You can choose another format or the original format as you like.

Step 3: Open the Parameter settings window and go to the Video Settings. Select the suitable video Resolution/Bitrate/Frame rate separately or lump them together.

Step 4: Select an output destination and hit the Run button to start compressing H264.

Method 3: Compress H264 Videos by Cutting the Unwanted Parts (High Quality Preserved)

If your videos have some nonsense parts like ads or black bars, you can remove the unnecessary parts to reduce the file size. And this way will also keep the high quality. Here is how:

Step 1: Run the program and enter the Converter module. Drag and drop the source H264 videos into the converter.

Step 2: In the video toolbar, click the scissors icon to trim the unwanted parts on the timeline and save the wanted parts. You can further use the crop tool by pressing the fourth icon on the toolbar to crop the nonsense pictures and customize the video playing area.

Note: Please keep the output and input bit rate consistent.

Step 3: Select an output format by hitting the right-side format image to bring out the format library.

Step 4: Click the inverted triangle button to specify a destination folder. Finally, press Run to start the process.

Method 4. Use the Batch Compression Button

HD Video Converter Factory Pro also offers a direct way to compress video with its batch compression button. This way is suitable for users who know little about encoding codecs, and compression techniques. To activate this feature, you need to add at least two video files.

Step 1: Launch the program and enter the Converter module. Drag and drop the source H264 videos into the converter.

Step 2. Click the format image on the right side and then select a preferred output format under the “Video” or other tabs.

Step 3. Click the bottom blue “Batch compression” button next to the “Run” button to activate the feature. Once it turns orange, drag the slider to the right to increase the compression ratio. The estimated output file size will change as you drag it to the right. But keep in mind that the higher the compression ratio is, the smaller the file size, and more quality loss.

Step 4. Hit the bottom downward arrow to specify a destination for the compressed MPEG4 videos. At last, click "Run" to start the compression.
