My friends send 12 episode of anime, consist of 720p resolution just around 740MB!
not single file 740MB, ALL 12 episode just 740MB with HD quality.... I wonder how they do that? how they compress that small? what software did they use? |

Maybe you need google search IFME, then you find it

Highly compressed without losing quality, is impossible.
Most video encoders like h264 and h265 are lossy compressor(by default), they discards the data depends on the settings. |

Upon trying so called "IFME", I impressed! It shrink so much smaller,

QUOTE(cracksys @ Nov 16 2014, 10:54 PM) only applies to anime. Noise only appear if the video decoder does not have deblocking filter, like the ealier MPEG1/2 and MPEG4-ASP (aka DivX/Xvid)you do that to normal movies, you'd get a lot of noise. H264 and H265 are enabled by default, so the lower the bit rate, the blurrier the video. And if the deblocking filter disabled you will see a lot of macroblock artifacts or the video simply looks distorted. |

QUOTE(Hikari Natsumi @ Nov 16 2014, 11:59 PM) I not sure, here the result: The quality degradation is there, just barely noticeable. But i guess Anime source is fine since your priority is to reduce the file size.1. x264: 38.4 MB (40,345,268 bytes) 2. x265: 23.9 MB (25,155,477 bytes) Original: gsmarena_v001.mp4: 79.9 MB (83,836,482 bytes) too bad 4K video kills my CPU = = DVD-R/W already a lot of cheaper isn't it?  Puny desktop CPU cant really do much, eg Quad core CPU, which only have 2 cores for decoding, and 2 cores for encoding. Unless the transcoder software support GPU assisted encoding and decoding. Not to mention it just 8 bit, 10 bit encoding are much slower. |

I often see "Anime4000" on "console" tab. I feel want to ask him, did he join this forum? |

Most decoder and GPU already support h264 decoding, while currently only Nvidia support 4K h264 GPU assisted decoding. for Encoding, we gotta wait for a while. But GPU assisted encoding usually have lower quality. |

But GPU assisted encoding usually have lower quality. I used a lot GPU based encoder, quality super bad! Found this...  I test on my AMD PhenomII X6 3GHz vs Core i5 480M... Intel win, I notice that Encoding speed is count on CPU Instruction Set, not more core mean more speed. This post has been edited by Hikari Natsumi: Nov 18 2014, 09:43 PM |
