H.264 Encoder 1.5

H.264/Advanced Video Coding (AVC) is an industry standard for video compression. The H.264 standard is also known as MPEG-4 Part 10 and is a successor to earlier standards such as MPEG-2 and MPEG-4. An ITU standard for compressing video based on MPEG-4 that is popular, especially for high-definition video. AVC stands for Advanced Video Coding. Actually its identical to H.264 so you can find it as H.264, H.264/AVC, H.264/MPEG-4 AVC or MPEG-4 Part 10.

Taking advantage of today's high-speed chips, H.264 delivers MPEG-4 quality with a frame size up to four times greater. It can also provide MPEG-2 quality at a reduced data rate, requiring as little as one third the original bandwidths. You can think it as the ¡°successor¡± of the existing formats (MPEG-2, DivX, XviD etc) as it aims in offering similar video quality in half the size of the formats mentioned before.

What can H.264 Encoder do for you
H.264 Encoder can encode other video files to H.264/AVC encoded video file, with this small but powerful tool, you can create creating an H.264 movie by yourself, it is one good utility for answer the question "How to create an H.264 video", this software is easy to use very much, help any beginners to create high in minutes. The incredible quality and efficiency of H.264 really brings video to life on internet or mobile phones. H.264/AVC can encode video with approximately 3 times fewer bits than comparable MPEG-2 encoders. This program offers fast encoding speed, professional quality, at the best, it is small and FREE.



How to use
Select one Video Source
Click "Open" button to select one source video file, H.264 Encoder support almost existing video formats, include: MPEG-2, DivX, XviD etc.


Input the Output File
Click "Browse" to browse and set one output file name. The default file extension is ".mp4", but you can use other file extension (like '.avi').


Choice one of encoding settings
Read "Encoding Setting Guidelines" to dind more info about this.


Encode to H264 video
Please make sure your pc have enough disk space to save the output file (Read "System Requirements").

Encoding Setting Guidelines
Program support encoding settings include:
Full High Definition (1920 x 1080)
Commonly Used High Definition (1280 x 720)
Standard Definition (640 x 480)
Internet-size Content (320 x 240)
3G Content (176 x 144)
High Quality (Same Size with Source)
Normal Quality (Same Size with Source)
Fast Speed (Same Size with Source)
For H.264, here are some general guidelines:
For a frame size of 1920 x 1080 (full high definition), choose a data rate of 7,000-8,000 Kbps.
For a frame size of 1280 x 720 (commonly-used high definition), choose a data rate of 5,000-6,000 Kbps.
For a frame size of 640 x 480 (standard definition), choose a data rate of 1,000-2,000 Kbps.
For a frame size of 320 x 240 (Internet-size content), choose a data rate of 300-500 Kbps.
For a frame size of 176 x 144 (3G), choose a data rate of 50-60 Kbps for 10-15 fps content, or up to 150-200 Kbps for 24-30 fps content.
File Extension for H264
You may come across all kind of file extensions and still the codec can be H264:
.avi - Yes, people use .avi for H264 videos too!
.mp4 - Nero Recode and Quicktime use this format. Better than AVI as you can store AAC audio as well (Default).
.mkv - Matroska container - can support many video and audio formats. Have a look here for more info.
.h264 - This extension is not commonly used. Maybe in the future.
