Compress and Reduce Video with Handbrake

digisns76 No Comments

Can you image that an uncompressed 1080p Full HD video can reach 806 GB at 24FPS and 90 minutes in length? That is really spectacular. When your storage space is not enough for storing more videos, but in the other hand, you are reluctant to give up some videos, so you need to compress the video size.

To make the video size smaller, firstly you need to know the video compression is achieved by removing certain data from the video sequence. There are mainly two types of compression: remove unnecessary redundant data or remove insignificant/less important data. The firt type can exceedingly compress and reduce video size with virtually no quality loss while the second one would dramaticly shirnk video size at the expense of certain quality loss. So how to make the first one happen, the key is to change the video codec rahter than video settings(resolution, bit rate, frame rate, and so on).

When you search the video compressor, Handbrake will be in sight as it’s a free and open-source transcoder for digital video files. Although it is very famous in this area, we still need to test it. Below is the specific steps of compressing video size with Handbrake with no qaulity loss.

Part 1 – How to Use Handbrake to Compress Video with Lossless Quality

As we metioned above, the efficient way to compress video size without quality loss is to change the video codec to another. Here comes the question, change to what codec? If you are not the greenhand in this area of video format, you must blurt out HEVC, aka H.265. As we all know, the most used codec should be AVC, H.264 codec, it can be accepted well by almost all devices. H.265 is a new one, compared to its precedent – H.264, HEVC promises a 50% storage reduction as its algorithm uses efficient coding by encoding video at the lowest possible bit rate while maintaining high image quality level. In the near future, it will take the place of H.264 and dominate the video market. It allows streaming 4k UHD video to become an easier job. The next we will show you how to transcode video to H.265 with Handbrake without lossing quality.

Step 1: Import H.264 MP4 (optinal) Video.
Fire up Handbrake 1.1.0 after the download and installation are finished. Drop a file or folder to Handbrake or load MP4 1080p video via "File" option .

Step 2: Choose Output Format and Preset.
Select "MP4" as output format and "Apple 1080p30 Surround" as output preset.

step 2

Step 3: Opt for H265 as Video Codec.
Click "Video" option and choose H265 (x265), H265 (10 bit) or H265 (12 bit) as video codec. BTW: to know the difference between H265 10 bit and H265 12 bit, you can check the explaination of color depth to know more.

Step 4: Compress H264 to H265 Now.
Tap "Start Encode" button and this free video compressor will begin to compress MP4 (H264) to H265 (x265) video at Intel QSV hardware accelerated speed (enable it from "Preferences").

Several mins later, the H264 to H265 (x265) compression, as well as H264 to H265 10 bit/12 bit compression is accomplished. The output file size and quality results are listed below:

Input Video: MP4 (H264), 1080p Full HD, 23.98FPS 
Duration: 38 minutes; File Size: 1.22GB
Output Video File Size Video Quality Frame Rate Compression Ratio Compression Time
H265 (x265) 565MB Intact 23.98FPS 55% 1 hr 42mins 5s
H265 10 bit (x265) 572MB Intact 23.98FPS 54% 2 hr 39mins
H265 12 bit (x265) 587MB Intact 23.98FPS 53% 2 hr 51mins 36s

From the test data, it’s clear to see that HEVC (H265) does an amazing job in video compression with 55% compression ratio to reduce H264 size from 1.22GB to 565MB while keeping the untouched quality. Of course, there is also a downside in HEVC. That is time consuming in HEVC video encoding using Handbrake (Intel QSV hardware decoding enabled), which might discourage lots of users from using Handbrake to compress H264 to H265.

If you do wanna compress H264 to H265 for smaller file size and better quality at the precondition of time saving, then you can consider to try the best Handbrake alternative – Pavtube Video Converter Ultimate (to get Mac version) which takes full advantage of the NVIDIA CUDA technology and AMD® Accelerated Parallel Processing (APP) to largely accelerate H.264/H.265 video encoding speed. What else can this software do for you?

Compress Videos for WhatsApp with Best Quality

digisns76 No Comments

WhatsApp is a freeware and cross-platform messaging and Voice over IP (VoIP) service owned by Facebook. The application allows the sending of text messages and voice calls, as well as video calls, images and other media, documents, and user location. But the size limit of Whatsapp is driving users crazy. You even can not upload a 1-minute video recorded in 720p, while where the 4k is becoming a standard on smartphones, GoPro, DSLR cameras etc, the mingy WhatsApp size limit seems to be rediculous. But now, if you want to share larger videos on it, you have to compress video for Whatsapp.

WhatsApp’s Size Limit

The maximum allowed size for documents on WhatsApp is 100MB, while the maximum size limit of WhatsApp is shrunk to 16MB only. Do you have an idea of that size? Let’s see the common video sizes in our life. A 1 minute of iPhone video recorded at the lowest resolution 720P comes in 60MB or 40MB in HEVC. And the size goes up to 200MB for a 1-minute iPhone video at 4K 60fps. A typical camcorder will give you a 150MB for a 1 minute 1080P video. Therefore, in most cases, you will need to reduce video size for WhatsApp. But how to shrink large videos to WhatsApp’s tiny 16MB?

Make Your Video Ready for WhatsApp

To make your video ready for WhatsApp, you can try Pavtube Video Converter Ultimate (to get Mac version). In our daily life, video easily exceeds WhatsApp’s size limit, with Pavtube Compressor in hand, you can easily:

  • Reduce 8K, 6K, 4K ultra HD, Full HD 1080P, HD 720P by 50%-70% via converting to a more compressed video format, parameter adjusting, video editing and codec selecting for WhatsApp, Youtube, Facobook, Vimeo;
  • Downsize any videos from iPhone, iPad, webcams, GoPro cameras, DSLR, HD Flip cameras etc;
  • Compress videos in any formats covering HEVC H.265, AVCHD, MTS, H.264, MPEG4, AVI etc;
  • Compress video for WhatsApp by trimming, cropping, splitting, and other video editing features.

How to Compress Videos for WhatsApp?

Free download Windows version or Mac verison:

Step 1. Import 4K/HD/SD video you want to compress into this software

Click "File" to load the video you want to compress into this software. Or you can directly drag or drop video into the program.

Import 4K/HD/SD video you want to compress into this software

Step 2. Define the output video format.

Before you select the output video format, you have to know Whatsapp supports certain video formats only, namely MP4, AVI, MKV, MOV, FLV, 3GP. Furthermore, to downsize videos for WhatsApp, you should also know which WhatsApp format has the smallest file size. Let’s check the respective size of the major formats.

Apparently, 3GP, HEVC and WebM are the formats that have the smallest sizes. However, HEVC and WebM are not supported by WhatsApp. So if you want to send longer videos via WhatsApp, 3GP is a good choice. But if you want to reduce video file size for WhatsApp 16MB without losing quality as far as possible, MP4 H.264 will be your best bet.

To output video for WhatsApp, you can choose "H.264 Baseline Profile Video(*.mp4)" as the final output video format. You also can choose 3GP as you like.

Define the output video format.

Step 3. Compress video size

This software offers you three ways to compress your videos. You can choose one of them, or all of them to make the video standard for WhatsApp.

Option 1. Split video into small parts.

By clicking the "Split" button under the file displaying list, checking "Enable" to enable it, and then you can split the file by file count, time length, or file size according to your own needs.

Split video into small parts.

Option 2. Trim/Crop/ video.

Select an item on the main interface to active the "Editor" function, then click the Edit icon on the tool bar of main interface to open the Editor Window, you can play and preview the original video and output effects. Also you can trim video length, crop video unwanted parts as you like.

Option 3. Adjuts video parameters.

The third way to compress video size is to lower the video resolution and bit rate. This software allows you to do this. In the "Profile Settings" you can adjust video codec, frame rate, bit rate, resolution, sample rate, channels according to your needs.

You can downscale video resolution and bit rate to make the video smaller. Normally, video size is based more on bit rate than resolution.

Adjuts video parameters.

Step 4. Start to compress video size for WhatsApp

When you have done all setting, go to press the Convert on the UI to start the compression process. When it’s over, you can get the generated video in the output folder you set. Now you will be free to upload any video to WhatsApp for sharing.

Compress H.264 4K/HD Video Size with Zero Quality Loss

digisns76 No Comments

As a video compression codec standard, H.264 is ubiquitous. Most deivces will play and export H.264 very well. Aiming at reducing the bendwith required for transmission of full-motion video, H.264 achieves it very well compared to MPEG-4. But as there pops up a new codec – HEVC, H.264 pale beside this new one. HEVC promises a 50% storage reduction as its algorithm uses efficient coding by encoding video at the lowest possible bit rate while maintaining a high image quality level.

H.265 compresses your data so much more efficiently, using it as your video compression tool will drop your bandwidth and storage requirements by roughly 50%. The table below compares the recommended bandwidth for H.264 vs. H.265 encoding.
