Today, I'd like to introduce a plug-in of Huisheng Huiying x264vfw; I found some related information from the Internet , as follows ;

x264 It's based on H.264 A free open source encoder for , There are currently two versions :cli( Command line ) Version and vfw edition .VFW Is in Windows It's a special way to encode under , It exists in the form of a dynamic link library , Can be used by any avi Compression tool ( Such as EO VIDEO) call .x264vfw yes x264 Of vfw edition , because x264 Our development environment is linux, therefore x264vfw stay 2006 year 10 Stop updating at the beginning of the month ; Although stopped updating , But the function is still very easy to use .

X264vfw The encoder is a Can convert video coding application tools , Through this software , We can convert a normal video stream into a H.264/ MPEG-4 AVC Format video stream , The software can set the conversion parameters , You can freely control the quality of the video , Debug the standard video stream , The software VFW The patterns are very rich , You can choose H264、X264AVC1VSSH Wait for different encoders to correct , Effectively improve the quality of video playback , In the use of Huisheng Huiying 、AE、CS4 And other professional video processing software x264 The support of the encoder is needed when encoding video .

The above is just for general understanding , It's all bullshit , I'll talk about the function of this plug-in in the meeting , It can greatly reduce the size of the video , Only when the production project format is DV/AVI We use , I believe my friends all know “DV/AVI” What's the use of this , It's custom video resolution , For example, set the resolution of the project to 800*800, That's the size of Taobao's main picture ; Now let's operate it , Make a comparison .

First , When this plug-in is not installed , The custom resolution is 800*800, Only plug in the system's own 5 Picture material , The video duration is 15 second , The output video size is as follows ; The expected output size is 696M, As one can imagine , If the output duration is 5 Minutes , The video size is at least 10 individual G;
