Use HandBrake as an MP4 Compressor for Windows 10?

HandBrake is a well-known video compressor for Windows 10. It will import MP4 videos and will compress MP4 videos by converting MP4 into HEVC and adjusting the parameters. However, HandBrake isn't an easy-to-use MP4 compressor for Windows 10. If you're not a tech-savvy guy, it's easy to get stuck in those complicated settings. In the end, you may get a bigger MP4 file, or compress but with much quality loss.

"I have a lot of mp4 files I'd like to compress to save space. I've tried Handbrake but it makes output files bigger than the originals. Anything else I can try?"
"I have tried the program Handbrake and had a couple of issues with it. For some strange reason the file always deletes itself after it's finished compressing. It seems to be a common issue with Handbrake if you google it, but I don't believe there is a fix yet."

Any Online MP4 Compressor for Windows 10?

Opponents of desktop-based program argue that an online MP4 compressor is enough to reduce MP4 file size on Windows 10. Yes, sometimes online service offers MP4 compression. But it's necessary to point out the most common issues with online MP4 video compressors.

1. Online MP4 compression tools, such as Convert.Files and Zamzar, are filled with ads.
2. They have limitations on input file size, maybe 50MB. If your MP4 file is larger than the maximum size, you have to pay a high price for it.
3. Users may be rejected to compress MP4 files on Windows 10 unless an account is registered.
4. Email address is always required to receive download link of compressed MP4 files, which may contain virus or other malware.
5. Online MP4 compressors cost more time, because they rely on network bandwidth, and support one-by-one compression only.

How to Compress MP4 without Quality Loss using the Best MP4 Compressor for Windows 10?

WinX HD Video Converter Deluxe stands out as the best MP4 compressor for Windows. As a professional desktop-based video compressor, it is much easier than Handbrake, and don't have any disadvantage that online MP4 compressors own. It allows you to compress MP4 videos on Windows 10 through different ways.

1. Choose a more compressed codec.

If your target MP4 video is encoded with MPEG-4, then re-encode it to AVC/H.264. But if it is encoded with H.264, you can compress this MP4 video to HEVC/H.265 - the successor of AVC/H.264. Compared to its predecessor, HEVC/H.265 offers about double the data compression ratio at the same level of video quality. By testing, a MP4 video could be reduced by about 60% after converting to HEVC.

2. Decrease MP4 video resolution.

Got a MP4 video in 4K? Just reduce the resolution if you don't have a 4K-ready TV or monitor to play it on. Sometimes we don't need super high definition video and our eyes can't tell the subtle difference. Video will look perfect if it fits our device perfectly. So if your video resolution is higher than your display resolution, lowering resolution will be a good way. You won't see obvious quality loss. This MP4 compressor is available to customize video resolution on Windows 10. You can choose one from premade options or type in any values.

Here we list some common video resolutions for your information. You can check the original resolution and choose one level below it.

2160p (3840×2160), 1440p (2560×1440), 1080p (1920×1080), 720p (1280×720), 480p (854×480), 360p (640×360), 240p (426×240)

3. Lower bit rate

The lower bit rate you set, the smaller file size you get. However, you're not suggested to put a too small value, if you don't want to lose too much quality after compressing MP4 video. To keep a relatively high quality, you're advised to reduce bit rate by 20% to 30%. For regular video where music/audio isn't too important, you can choose 160 as the audio bit rate.

4. Crop and trim off unwanted part.

This Windows 10 MP4 compression software also enables you to shrink file by cropping and trimming off unwanted parts, such as the ads, titles, trailers, titbits, black bars, etc. Simply drag the bar or set start and end time, you'll cut off unwanted footage. Tick the box of Enable Crop, you'll be able to cut away black edges or unimportant area.

5. Drag the bar to LQ.

By default, this MP4 compressor sets output profile at the middle position between LQ and HQ. To compress MP4 video without changing file format, resolution or other parameters, you can simply drag the bar to LQ. It will reduce about half size.

As for the frame rate, you'd better keep your MP4 video as the original. This is because unprofessional settings may make movement in your video seem jerky or unnatural.
