How to Compress MOV Video File with Smaller Size, Better Quality

Video Processing: Reduce MOV File Size with Original Quality for Easily Sharing With the World

Either for travel or for family, amounts of videos shot on iPhones as MOV turn to be treasures full of significant moments. Gradually, the size of video folder grows and you have to compress MOV files to small size with best quality for disc burning, uploading to YouTube, Facebook, Twitter, Whatapp, Email, etc.

"I have a monster 4GB folder full of .MOV files shot on an iPhone that I need to compress small enough to fit on two or three 700MB discs - or a 2GB flash drive. I used the Archive Utility to zip it and the folder is still the same size as the original. Is it possible to compress and if so, how?"

If you fail to compress MOV video file by making a ZIP, our solution can lead you to reduce MOV file size while keeping the best quality.

Your Must-Have MOV Video Compressor – WinX HD Video Converter Deluxe

• Convert MOV to H.264, HEVC and other advanced formats featuring higher compression ratio to reduce video file size.
• Compress 4K/HD MOV files to 1080p, 720p or more for smoothly running on low-end computers.
• With Hardware Acceleration tech by utilizing Intel QSV/NVIDIA NEVC, it boosts video compression speed and ensures the possible highest quality (nearly lossless) after resizing thanks to hardware processing.

Tips on Compressing MOV File:

Part 1. What Factors Are Affecting MOV File Size
iPhone gives us the information about the size of one-minute recorded MOV video:
• 60 MB with 720p HD at 30 fps > 130 MB with 1080p HD at 30 fps
• 175 MB with 1080p HD at 60 fps > 350 MB with 4K at 30 fps

It is a proven theory that video file size is affected by bit rate[1] and length, which has nothing to do with resolution or frame rate. There is an algorithm:
[Audio bit rate (Kb)/8 + Video bit rate (Kb)/8] x length (seconds) = file size (MB)
Note: Kb = Kbit, KB = KByte, 1KB = 8Kb, 1MB = 1024KB

But, why does this iPhone list seemingly indicate that video file size can be affected by resolution[2] and frame rate[3]? A video in higher resolution commonly features higher bit rate so that you may get a bigger MOV file with higher resolution. Frame rate tells how many frames (consecutive images) appear on a display per second. If you get a video with variable bit rate, frame rate can affect video file size. Higher frame rate shows that more frames appear per seconds leading to higher bit rate and larger size.

Nowadays, advanced video compression standards[4] are developed to obtain the same level of quality while using lower bit rate – for example, HEVC, H.264, VP9 – making videos become smaller but maintain high quality.

Depending on different situations, you can choose to transcode video, shorten duration, adjust bit rate/frame rate or downscale resolution to compress MOV.

Part 2. Which Program is Qualified to Reduce MOV File Size With High Quality
WinX HD Video Converter Deluxe stands out as an easy-to-use video compressor which excels at reducing video file size in a few clicks. With the support of hundreds of video codecs, it allows you to convert MOV to HEVC, H.264, VP9 etc, with smaller size. Video trimming feature helps you to cut unwanted or NG parts off whole video. Certainly, video/audio parameters incl. bit rate, frame rate, resolution can be customized as you like.

WinX HD Video Converter Deluxe wraps Hardware Acceleration tech to greatly increase efficiency and performance to compress 4K/HD MOV videos. The utilization of Intel QSV and NVIDIA NEVCN accelerates video encoding/decoding speed while lowering down CPU usage for other tasks. Not only for speed, can video quality be reserved in maximum (almost lossless) thanks to Hardware Acceleration.

Part 3. Step-by-step Guide on How to Compress a MOV file to Smaller Size with Better Quality

Free download & install WinX HD Video Converter Deluxe on your PC/Mac. Then, follow the steps below to compress MOV files. Discover MOV Compression Test Results Here >>

Compress MOV Video

Step 1. Input a MOV File
Launch WinX HD Video Converter Deluxe and click + Video button to add the source MOV file.

Step 2. Compress and Transcode MKV File, for example, Compress MOV to MP4.
Except MP4, there are a wide range of formats for you to choose, such as compress MOV to HEVC, AVI, FLV, WMV, M4V, etc. Just select a favorable format as output format, then click OK.

1. MP4 Video (codec: h264+aac) is the most recommended format for it not only delivers smaller size, better quality, but it has the highest compatibility with applications and devices. Although HEVC is another available choice which doubles data compression ratio than H.264, it requires better hardware and lacks of wide compatibility at present.
2. 2K MP4 Video is preset as an output format enabling you to downscaling 4K to 2K directly.

Optional Step. Cut MOV Video
Click Edit button. Select Trim tab and click Enable Trim option. Two cursors appear at the start and end of the process bar under preview window. Drag them to select desired parts. You can also manually input specific start/end time. After that, click Apply to All.

Step 3. Adjust Parameters
Click the gear button to access to video/audio settings window. Bit rate, frame rate and resolution can be lowered for video downsizing.

1. If the bit rate is constant, it is useless to reduce file size via decreasing resolution and frame rate. If you have decreased bit rate, a lower resolution may deliver better image quality.
2. If the bit rate is variable, you can decrease frame rate to make video smaller. But it may influence image smoothness – with mosaics.
3. If you have a low-end device or computer, it is suggested to lower bit rate, resolution and frame rate of MOV (especially for 4K MOV) for a smooth playback. But if you have a powerful device/computer or want to keep a super quality after uploading online, you'd better only transcode and trim MOV.

Step 4. Turn on Hardware Acceleration to Speed up the MOV Compression Process
Check one of Hardware Encoders (Intel or nVIDIA according to your GPU) to accelerate the mov compression and maintain best output quality.

Step 5. Start Compressing the MOV File
Click Browse button to define a new folder to save the compressed file if necessary. Click RUN button to start reduce MOV file size while preserving best output quality.
