STY動作好快啊. ^^
才剛想轉文章的說.

(翻譯兼觀感)

這個CODEC的好處是符合ISO MPEG-4(advance simple profile level 5)規格,
所以壓出來的檔案能夠保證可以在XCARD,或是採用相同晶片的產品上播放.
(畢竟沒人知道DivX未來會不會改資料結構,雖然照現在來看應該是不會)

反正競爭才會有進步啦~

剛好收 AV Watch 的電子信，看到就順道繞過去看看
看完報導馬上給他抓下來試試看，除了上面兩位所提到的以外，還標榜「RMP4是目前所有 DivX Codec 中 Single Pass 的畫質與速度之佼佼者」...

有點給她心動，找個時間來給他試試看

那不是標榜, 是Sigma Designs的老王賣瓜....
不過我想其自信其來有自吧.

另外,在自己的板上收到了不相容回應,無法使用該CODEC,原因正在調查中.
可能有和某些CODEC相衝的疑慮. 詳情容後述.
(請有類似狀況的回應到本title下)

我安裝完也是無法使用,不管用VD還是AviUtl,
一輸出就掛掉,VD是access violation,AviUtl直接關掉,
已安裝codec除了windows原有的以外還有,
divx 4.12,divx 5.02 pro,ATI YUV12(mmc7.7),Sigma RMP4.

轉換PICVIDEO MJPEG壓縮的檔案時出現錯誤而無法轉換 ^^;

剛注意到Sigma Designs的MPEG4 Codec有一個獨特的功能
-支援"交錯式掃描".
http://www.realmagic.com/products/M...deo_encoder.htm
可暫時解決用DivX錄NTSC電視上29.97FPS的影像會產生交錯畫面,
用去交錯過濾器又會減損解析度的問題 ^^

重點是那句『single pass 的佼佼者』，要不是吹牛那就好了....
系統太龜做2 pass 好累。請問閣下的divx4.12怎麼灌的？我下載了版友提供
的divx5.02pro, 一灌就吃掉divx4.12, 屍骨無存....the playa變成divx player
2.0alpha, 這個倒是好，以前的the playa 在我的機器上老是有播放會頓
的問題，用media player6.01 powerdvd3.0 都沒事。divx player2.0alpha
的早送也可用，送的超快

要是飛馬牌 mjpeg 不吃，那這個只好割捨不用....除非回頭用huffyuv?
sty說的支****錯掃瞄似乎很有趣，可是能夠硬體直接抓mpeg4不掉格也
不是容易的事....所以這公司賣卡的空間就出來了

請問這個功能是寫在哪裡呢？我找不到，只有看到聰明型去交錯的功能介紹
Includes Intelligent Deinterlacing for interlaced to progressive scan conversion

--
在我的電腦上不能用，會顯示 Codec 指令的錯誤訊息，以前用 koepi 編譯的 XviD Codec 也會發生這種情況，該版本是用 ICC Compiler 的，有針對速度最佳化。
我的 CPU 是 K6-3，不知道是不是這個原因

在下是在這個PDF說明檔上看到的:

其中有一欄Interlaced Video Encoding Tools

Intelligent Deinterlacing
Deinterlacing is a technique that uses a pre-processing filter to convert interlaced
video into progressive video. It removes jagged-edge artifacts in moving objects on
interlaced video. Deinterlaced video performs well on non-interlaced monitors. If the
source video is progressive, this option should remain disabled. Interlaced Video
Encoding Tools REALmagic MPEG-4 Video Codec fully supports interlaced video encoding.
Interlaced video is most commonly found in material intended for TV broadcast.
For interlaced video, a “field” is the assembly of alternate lines of a frame.
An interlaced frame is composed of two fields: top and bottom. Each line of the
top field is spatially located immediately above the corresponding line of the
bottom field. In an interlaced frame, one of these two fields must display first,
and is labeled the first field. The first field can be the top field or the bottom
field of the frame. If interlaced video encoding is selected, the user must specify
whether the top field is displayed first.
In some cases, using alternate vertical scan generates better quality. REALmagic
MPEG-4 Video Codec provides this tool to improve interlaced video encoding quality.
Alternate vertical scan needs decoder support. The REALmagic Xcard fully supports
this function.
Depending on your decoder, header information may cause compatibility issues
during playback. The REALmagic Xcard supports RMP4, DX50, and DIVX.

Q: Why do I need to use deinterlacing?
A: Deinterlacing is not required; REALmagic MPEG-4 Video Codec fully supports interlaced
videoencoding. However, to play your video on a non-interlaced (VGA) monitor from an
interlaced videosource, deinterlacing improves playback quality by removing jagged-edge
artifacts in moving objects of interlaced video. Deinterlacing, by its nature,
is a lossy process.
