These days, whether self-shot or downloaded videos, are of ultra-high clarity and quality. But at the same time, it also means that the video size becomes very large. Despite the increasing capacity of hard drives and mobile phones, it is undeniable that sometimes people still need to condense videos for different purposes. If you still have no idea how to do that, HD Video Converter Factory Pro is a multi-functional and user-friendly program that provides six methods to condense video file size.
Run HD Video Converter Factory Pro, five main modules will present in front of your eyes: "Converter", "Downloader", "Recorder", "GIF Maker" and "Toolbox". To condense video size, open "Converter", click "Add Files" or "Add Video Folder" button to import your large-sized videos. Or, just drag and drop video files into the blank space.
Press the format profile on the right side to expand 500+ optimized presets. Head over to "Video" category and select "H265 for MP4", "H265 for MKV" or "VP9".
In a nutshell, HEVC (aka H.265) and VP9 are two advanced video compression standards and successors to the widely used H.264 and VP8, which offer up to 50% better data compression at the same level of video quality. Roughly speaking, it's considered as the lossless conversion when you convert video to HEVC or VP9.
After you select one preferred output format on the right side, press the "Batch compression" icon next to the output folder on the bottom to activate "Compression Setting Bar". Once the icon becomes orange, drag the slider to the right side to increase the compression ratio for video condensing.
Note: This method adopts lossy compression, the smaller the file size, the lower the video quality. You have to keep the balance between the quality and file size.
Once selected an output format, click on "Parameter settings" button underneath format profile to open a window, navigate to "Video Bit Rate" section, you're able to reduce the values or switch to VBR mode (Variable Bitrate) to condense video size.
In principle, this method is equivalent to adjusting "Compression Setting Bar", which both achieve file size compression at the expense of sacrificing video quality. In essence, the higher the video bit rate, the higher the quality of video.
To condense video file size, there is a "Quick setting" bar available underneath "Parameter settings" button, which allows you to downscale 8K to 4K, 4K to 1080p or 1080p to 720p for swift video condensing.
You have to know that resolution doesn't determine the video quality. But a video with higher resolution generally has a better quality, because cameras always record video at a higher bit rate for the larger resolution.
If the video is shot in 60fps or higher, open "Parameter settings" window and change the frame rate to 24fps or 30fps, which can also condense video size to a large extent.
You can also cut off the undesired part in a video to condense MP4 file size. Click "Scissors" icon on the toolbar to open "Trim" windows. Drag the two sliders to trim video, or input start time and end time for fine-tuning, then click OK. You're allowed to split video into multiple parts. If needed, you can also merge multiple video clips into one later.
After everything is all set, choose an output path on the bottom. Lastly, hit "Run" button to start to condense video files.
Similarly, you're able to condense MP4 file, condense MOV file and the like as well as condense video for email, Whatsapp, uploading, etc.
