H.264 vs H.265 — Convert H.264 to H.265

Part 1. H.264 vs H.265

Do you still remember those frustrating times when you were watching a video or a movie online and all of the sudden you experienced a loss of quality? Now it can be possible to stream high-quality videos in congested network environments in a faster and virtuous way. High Efficiency Video Coding (HEVC), aka H.265, is a video compression standard designed to substantially improve coding efficiency when compared to its precedent, the Advanced Video Coding (AVC), or H.264.

With the development of video streaming on the Internet over popular website such as Netflix and Youtube, and with 4k cameras gaining new ground in the market, a considerable amount of storage and bandwidth is required. 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.

I believe HEVC will revolutionize how video data is displayed, either online, on television and even in the surveillance industry. So, it won't long for HEVC to dominate the video date market, although now HEVC couldn't be accept by many device or media players, it's not too early for you to learn the way to convert H.264 to H.265.

Part 2. Convert H.264 to H.265

From above analysis, you may want to a way to convert H.264 to H.265, a super H.264 to H.265 converter you deserve. Pavtube Video Converter Ultimate | Mac comes as the winner from its competitors, which could convert non-H.265 videos ( MKV, MOV, MP4, AVI, H.264, MXF, MTS... ) to H.265 files and vice versa.

Moreover, it can convert 4k MP4, MOV, MKV, MXF, AVCHD and more to H.265 to save 50% storage space while keeping the original video quality. You can go to Settings window to keep the output video in 4k, or just compress 4k to 1080p or 720p. Fortunately, for those people who have a PC that are running with Nvidia GeForce Graphic Card, you can accelerate H.265 encoding speed with specific H.265 encoding software.

The rich-feature software also works as a video editor, you can personalize and retouch your video in clicks by trimming H.265 video length, cropping video ratio respect, adding external subtitles, removing or replacing audio, more feature here are waiting for you exploration.

Step by Step to Convert H.264 to H.265 video with ease

STEP 1. Add H.264 videos

Run the H.265 Video Converter program, go to the menu bar, select Add button to select the H.264 files you want to import. You can also directly drag the video files to the program for conversion. It supports batch conversion so you can import multiple files at a time.

STEP 2. Choose H.264 as output format

From the drop-down list of " Format" > "Common Video", you can select H.265 Video(*.mp4) as the target format.

Tip: You can change the format parameters by click the Settings bar. The video size, video encoder, frame rate, bit rate, audio encoder, channel and more other parameters can be adjusted in this Settings option.

Note: Normally, the video size is based more on video bit rate than video resolution.

STEP 3: Enable GPU Encode Acceleration.

Click "Tools" > "Options", in the opened "Options" window, click "Acceleration" menu, then check "Enable GPU Encode Acceleration" otpion so that the program will accelerate converion speed when encoding H.264 to H.265/HEVC codec.

STEP 4. Start conversion

When all the settings are done, click the Convert button to start encoding H.264 files to H.265 with 30X speed. The conversion time depends on your video size, computer performance, output settings, etc. Generally, it won't take too long. After the conversion, you'll get resulted H.265(HEVC) videos for better usage.
