还没用过，不知清晰度如何？

功能還蠻多的~
可以選擇預設壓縮容量
選擇做成ISO (尚未完成) 跟檔案格式
可以挑掉不要的影片音效字幕等~
也可以分別選擇各影片的壓縮比
直接DVDROM轉也蠻方便的

壓縮在40%左右的畫質看起來還不錯
不過通常太大的通會超過~:D

為什麼我複製完之後會沒有字幕ㄋ
可以教教我ㄇ
各位大大

現在正在測試中
發現幾個好玩的現象

1.壓縮筆的設定似乎是固定的
有四個選擇Level1 ~4
Level 1的壓縮比最小，Level4的最大
我拿的母片是7GB多的影片，Level4還顯示壓縮過後仍然有4.43GB
顯然仍然比4.38要大了一些
現在正在轉，不知道最後結果如何
2.我找不到自行設定壓縮比的地方
他似乎不能像PIC 一樣，任意調整比例
雖然有一個Custom的選項
能夠讓你選擇要保留的字幕、以及聲音
不過，影片的壓縮選擇仍然只有Level1~4四種而已
3.一個奇特的功能，我沒有測試
似乎可以選擇區碼ㄟ？
是指轉出來的片子，也可以自行加上區碼的保護嗎?
不知道有沒有人試過
搞不好可以把3區的改成5區的@@

暫時先這樣囉
待會還要用DVD2ONE壓一次
比較兩個的畫質

我現在也在測試，而且我想把PIC也加入比較。
因為我對畫質的要求最高。
我備份的DVD，向來是能分片就分片，很少壓縮。
但遇到約5GB左右的片，分也不是，不分也不是。
很頭痛，但要重壓的話又很不甘心。
所以雖然DVD2ONE很快，但對我來說誘惑不大。
如果用較慢的速度可以換到較高的畫質，對我來說還是有用的價值。
只是畫質的優劣很難有個較公平較有標準的比較法。
這幾天我一直在為計劃這件方案做準備，如今剛好又出了新程式。
可以順便來試試。

推薦你到 http://dvdbackup.come.to/
這個網站裡->>重壓縮主影片 ->> 點選->>使用dvdshrink壓縮
內有詳細的圖文解說。

抓了兩張圖
一張是用DVD2ONE壓的
另一個就是Shrink

我保留原來的bmp檔
避免轉檔的失真
個人比較上，覺得還是DVD2ONE比較好
我是用放大圖片來看
在相同的倍率下
Shrink的比較早發現格子狀的圖形
至於前面有人提到畫面會有閃動的現像
小弟這一次並沒有發現
不過，因為我沒有把整片看完，只是抓個圖片而已
目前就先這樣囉

另外，剛剛也仔細看了shrink的help檔案
那個regin選項，真的是選擇你要設定的區碼
也就是說，自己做出來的DVD5片子，也可已有區碼保護
(不過我懷疑有人會這麼做嗎？？）

我自己試用了壓回到未來III感覺畫質....很差
有點失望，但畢竟是免費的軟體，要求不能太高啦，抱歉沒將sample留下來，因為感覺品質不好，已經直接殺掉了，以上個人意見，僅供參考！

剛剛更新到1.03版了

更改部分:

Re-encoder:

Added extra encode levels. This is not a final solution to the encode interface, just a temporary measure.

Added "Still Movie" encoding: only copy the I-pictures, heavily compressed. This gives huge compression as an alternative to deletion of the entire video stream, which people seem to want, but re-encoder module can't handle, because it alters the navigation structure of the DVD. Audio and subpicture streams will still play normally.

Increased number of samples taken during analysis, so it takes 50% longer but gives more accurate expected sizes. Maybe this should be a user option.

The "not a system pack" error is fixed, by removing non-system packs during the re-encode, rather than throwing an error. I still don't know what these non-system packs are doing in the VOBS, or if they shouldn't be included instead. If they occur, a little message pops up after re-encode is finished.

Re-author:

Increased brightness of video preview in re-author module, add and crop dialogs. Preview windows in other modules are DirectDraw YUV surfaces for performance, so not so easy to modify.

Removed support for multi-angle from re-author. Too many problems. Adding support again will require a virtual rewrite of the re-author module. User is now offered only angle 1, which will prevent crashes.

Added a message next to "include menus" checkbox in re-author, so hopefully people will stop thinking they can, um, include menus.

Added code to strip all buttons and button commands from menus that are added in re-author, actually from anything that is added at all. Most of them contain invalid links or commands, esp. in the case of menu vobs because they move from the menu domain to the VTS domain when the re-authored DVD is built. I guess no buttons is better than invalid buttons.

General:

Fixed stupid bug where region and provider ID changes were written to the .IFO files but not the .BUP files, so they came out different.

Modified error reporting dialog. Now attempts to report the cause of an error using GetLastError() API.

Added check that source and destination folders are different. Not entirely foolproof because of shortcuts.

Just to make sure, encoding/copying will not proceed unless the destination folder is empty of DVD files.

Changed distribution name. From now on, DVDShrink103.exe, and so on. This seems to bugger up the list of recently-used-files which are stored in the registry under the old name, so they are reset when you first start the new version.

An undocumented feature: you can select "options..." from the system menu and delete the recent-used-file lists. Otherwise the lists can become full of invalid folders over time. Or you can just edit the registry
