User-knowing netizens will find that the mainstream video website has started using the H264 encoded FLV file, I think the H264 encoded FLV file, the same file size, the clarity is obvious than the ON2 VP6, but there is no use of ON2 VP8 encoding, no Know how ON2 VP8 is, whether it is better than H264. There is a special explanation that the H264 encoded FLV file requires Flash Player 9 and a higher version of H.264 video codec to play.
First introduce a method of making FLV files with Adobe Media Encoder CS4 software:
Adobe Media Encoder CS4 has a lot of updates, I think the most useful is support for F4V (F4V is Adobe to push new F4V streaming media format that supports H.264 after the FLV format is pushed in order to welcome the HD era. It is free, as long as you buy Adobe Flash CS4, you have it, we google, it is very convenient to find it, huh, huh.
For those who are familiar with Adobe software, use Adobe Media Encoder CS4 to a certain light car, after adding video files, set "Export Settings".
The output format is F4V. If you want to pass to the video website, you can modify the suffix to flv, but many video sites are uploaded, no matter what suffix will be compressed, and hit their own logo, it is more annoying, it is best to find not 2 Upload or pass to your own space.

Introduce a method for making FLV format video files with MediaCoder software:
MediaCoder Chinese name is an audio and video transfer express, is a free universal audio / video bulk transfer tool, which is developed by Chinese Huang Yizi, which integrates many excellent audio video codecs and tools from open source communities into a general purpose Solution, it can convert audio, video files between various formats. It is now mainly used to convert H264 features. Be
Pay attention to the audio, video, resolution settings.
Audio setting
Audio setting (no fault, container is selected MP4)
Resolution setting (according to the size of the FLV player, I use 545x410)
Conversion results:
Original file:
Size: 164M code: WMV3 code stream: 9502K resolution: 1280720 Audio: 440K 16-bit 48khz video: 9000K 24-bit
After the conversion files:
Format: MP4 size: 15.2m code: H.264 code stream: 882K resolution: 545410 Audio: 65K 16-bit 48khz video: 816K conversion software: mediacoder0.6.2.4222
Format: MP4 size: 5.71M code: H.264 code stream: 330K resolution: 546410 Audio: 65K 16-bit 48khz video: 263K conversion software: mediacoder0.6.2.4222
Format: F4V Size: 15.2m Code: H.264 Code Stream: 876K Resolution: 545410 Audio: 64K 16-bit 48kHz Video: 804K Conversion Software: Adobe Media Encoder CS4
Format: F4V size: 5.71M code: H.264 code stream: 330K resolution: 545 × 410 audio: 64K 16-bit 48khz video: 263K conversion software: Adobe Media Encoder CS4
Clearness comparison:
Visually, the same size file is similar, MediaCoder is better than Adobe Media Encoder CS4 in the background display, and in the close-up character, it is better than Adobe Media Encoder CS4, the difference is not too big, or it may be a visual reason.
Another big problem is that I haven't found a video wide setting of MediaCoder. The film, the 1280x720 film, the compressed proportion should be 545x307, after I set the resolution 545x410, the noise should be filled with black and white, this Adobe Media Encoder CS4 is automatically done, but MEDIACODER has no success, tested more than 10 methods, including the automatic resolution "545x-1", no, forcibly set to 545x307, play automatically, it is high, don't know Is it I still don't understand the MEDIACODER's picture setting, or it is not supported by MediaCoder.
