Formats 格式 VCD - VCD is an mpeg1 based format, with a constant bitrate of 1150kbit at a resolution of 352x240 (NTSC). VCDs are generally used for lower quality transfers (CAM/TS/TC/Screener(VHS)/TVrip(analog) in order to make smaller file sizes, and fit as much on a single disc as possible. Both VCDs and SVCDs are timed in minutes, rather than MB, so when looking at an mpeg, it may appear larger than the disc capacity, and in reality u can fit 74min on a CDR74. VCD是一種使用MPEG-1編碼的格式. 它的bitrate固定在1150Kbps, 解析度是 352*240 (NTSC). VCD通常被用在低畫質的轉換上, 以便達到較低的檔案大小, 而且通常盡可能製作成能夠儲存在一個CD上. VCD和SVCD都是使用時間來計算長度 (而不是使用MB), 因此當將VCD中的影片在MPEG格式的大小可能大於光碟的容量, 但實際你可以將它儲存在一個CDR74中. SVCD - SVCD is an mpeg2 based (same as DVD) which allows variable bit-rates of up to 2500kbits at a resolution of 480x480 (NTSC) which is then decompressed into a 4:3 aspect ratio when played back. Due to the variable bit-rate, the length you can fit on a single CDR is not fixed, but generally between 35-60 Mins are the most common. To get a better SVCD encode using variable bit-rates, it is important to use multiple "passes". this takes a lot longer, but the results are far clearer. SVCD是一個MPEG-2編碼 (和DVD相同) 的格式. 它的bitrate在480*480的解析度時可以達到2500Kbps (在播放時被解壓縮成4:3). 由於使用變動的bitrate, 可以被儲存在一個CD-R中的長度並不是固定的, 通常在35~60分鐘之間. 要在使用變動bitrate編碼SVCD時, 使用多次pass是十分重要的. 這雖然會消耗相當多的時間, 但是編碼後的畫質會清晰許多. XVCD/XSVCD - These are basically VCD/SVCD that don't obey the "rules". They are both capable of much higher resolutions and bit-rates, but it all depends on the player to whether the disc can be played. X(S)VCD are total non-standards, and are usually for home-ripping by people who don't intend to release them. 這些格式簡單來說就是不遵守規範的VCD / SVCD. 它們可以使用更高的bitrate 和解析度, 但是不是每個VCD Player都能夠播放它們. X(S)VCD根本不是一個規格. 它們通常被用在私人用途上. DivX / XviD - DivX is a format designed for multimedia platforms. It uses two codecs, one low motion, one high motion. Most older films were encoded in low motion only, and they have problems with high motion too. A method known as SBC (Smart Bit-rate Control) was developed which switches codecs at the encoding stage, making a much better print. The format is Ana orphic and the bit-rate/resolution are inter- changeable. Due to the higher processing power required, and the different codecs for playback, its unlikely we'll see a DVD player capable of play DivX for quite a while, if at all. There have been players in development which are supposedly capable, but nothing has ever arisen. The majority of PROPER DivX rips (not Re-Encs) are taken from DVDs, and generally up to 2hours in good quality is possible per disc. Various codecs exist, most popular being the original Divx3.11a and the new XviD codecs. DivX是一個為了多媒體平台而設計的格式. 它使用兩個不同的codec, 分別處理少量及多量動作的部分. 老舊的DivX影片通常只使用少動作的codec來編碼, 因此在多動作的部分它們通常會有一些問題. 於是發展了SBC (Smart Bit-rate Control) 這個編碼方式. 它在編碼的階段就即時選擇適合的codec, 因此畫質有了極大的改善. DivX的bitrate和解析度是可以交換的. 由於DivX解碼需要強大的處理能力, 短期內應該不會有播放DivX能力的DVD Player. 雖然有人正在研發, 但是目前沒有任何結果 (按: 可以播DivX的DVD Player出了一兩年了吧?) 大多數的PROPER DivX擷取 (未重新編碼) 是取自DVD. 一個光碟通常可以儲存 2小時擁有良好畫質的影片. DivX有許多不同的codec, 最流行的是原始的 Divx3.11a和新的XviD. CVD - CVD is a combination of VCD and SVCD formats, and is generally supported by a majority of DVD players. It supports MPEG2 bit-rates of SVCD, but uses a resolution of 352x480(ntsc) as the horizontal resolution is generally less important. Currently no groups release in CVD. CVD (China Video Disc) 是VCD和SVCD的組合, 它被大多數的DVD Player支援. CVD使用MPEG-2以及和SVCD相同的bitrate, 但是解析度則是352*480 (由於垂直解析度通常較不重要). 目前沒有任何"group"發表CVD格式的影片. DVD-R - Is the recordable DVD solution that seems to be the most popular (out of DVD-RAM, DVD-R and DVD+R). it holds 4.7gb of data per side, and double sided discs are available, so discs can hold nearly 10gb in some circumstances. SVCD mpeg2 images must be converted before they can be burnt to DVD-R and played successfully. DVD>DVDR copies are possible, but sometimes extras/languages have to be removed to stick within the available 4.7gb. DVD-R是可錄製的DVD的解決方案, 目前在DVD-R, DVD+R及DVD-RAM中看來是最為流行的 (按: 目前似乎是DVD+R?). DVD-R單面可儲存4.7GB的資料, 同時也有雙面的DVD-R, 使得在某些情況下DVD-R可以儲存接近10GB的資料. SVCD中的MPEG-2 影片必須先經過轉換才能燒錄成DVD Video. DVD到DVD-R的轉換是可行的, 但有時額外的片段及語言必須被移除, 以儲存在4.7GB的DVD-R中. MiniDVD - MiniDVD/cDVD is the same format as DVD but on a standard CDR/CDRW. Because of the high resolution/bit-rates, its only possible to fit about 18-21 mins of footage per disc, and the format is only compatible with a few players. MiniDVD使用和DVD相同的格式, 但是使用CD-R / CD-RW作為儲存媒體. 由於較高的解析度及bitrate, MiniDVD只能放入21分鐘內的影片. MiniDVD只被某些 DVD Player支援. Misc Info 綜合資訊 Regional Coding - This was designed to stop people buying American DVDs and watching them earlier in other countries, or for older films where world distribution is handled by different companies. A lot of players can either be hacked with a chip, or via a remote to disable this. 區碼的目的是防止美國的DVD被購買並提早銷售到其他國家, 也為了解決某些早期影片的全球銷售權被其他公司掌握的問題. 許多DVD Player都可以藉由一個晶片甚至是遙控器來取消區碼 (Region-Free / 全區) RCE - RCE (Regional Coding Enhancement) was designed to overcome "Multiregion" players, but it had a lot of faults and was overcome. Very few titles are RCE encoded now, and it was very unpopular. 加強型區碼被設計來打敗全區DVD Player, 但是因為本身有許多錯誤而失敗了. 極少數的影片使用加強型區碼. Macrovision - Macrovision is the copy protection employed on most commercial DVDs. Its a system that will display lines and darken the images of copies that are made by sending the VHS signals it can't understand. Certain DVD players (for example the Dansai 852 from Tescos) have a secret menu where you can disable the macrovision, or a "video stabaliser" costs about 30UKP from Maplin (www.maplin.co.uk). Macrovision是一個被廣泛使用在商業DVD上的防拷方式. 在進行未經授權的數位複製時, DVD內的軟體會啟動Macrovision, 借由輸出錯誤的VHS訊號, 來扭曲 , 黑化輸出的影像 (前面那句我覺得原文怪怪的, 我就自己寫了). 某些DVD Player (像是Tescos的Dansai 852) 有個秘密選單可以關閉Macrovision, 也可以利用一個30英鎊的"影像穩定器"來關閉Macrovision. NTSC/PAL - NTSC and PAL are the two main standards used across the world. NTSC has a higher frame rate than pal (29fps compared to 25fps) but PAL has an increased resolution, and gives off a generally sharper picture. Playing NTSC discs on PAL systems seems a lot easier than vice-versa, which is good news for the Brits. An RGB enabled scart lead will play an NTSC picture in full colour on most modern tv sets, but to record this to a VHS tape, you will need to convert it to PAL50 (not PAL60 as the majority of DVD players do.) This is either achieved by an expensive converter box (in the regions of ￡200+), an onboard converter (such as the Dansai 852 / certain Daewoos / Samsung 709 ) or using a World Standards VCR which can record in any format. NTSC和PAL是兩個主要的影像格式. NTSC擁有較高的frame rate (29.97FPS, PAL 為25FPS), 但是PAL擁有較高的解析度, 通常也有較瑞利的影像. 在PAL系統上播放NTSC的光碟比反過來容易多了 (對英國人來說是個好消息).一個有RGB的 "scart lead"可以在PAL的電視上播放彩色的NTSC光碟. 但是若要將NTSC光碟錄製在VHS錄影帶上, 就需要將它轉換為PAL50格式 (並非DVD Player使用的PAL60) . 這可以利用一個昂貴 (200英鎊以上) 的轉接盒, 一個DVD Player內建的轉換器或是一個世界標準的錄影機. ====================================================================== 有些原文明顯的錯誤我就直接改了, 像是NTSC寫成NTCS, NTSC的29FPS (應為29.97FPS) 等等. 有些實在不知道怎麼翻的像"scart lead"就保留原文. 有些原文裡面out-dated的東西 (像是DVD Player播放DivX) , 用"按"來標示. 後面和影像格式不相關的就先不翻了...唸微方去...>"< -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 210.68.184.96 ※ 編輯: ithinkurdumb 來自: 210.68.184.96 (01/12 22:23)
