請教兩個問題,關於非正方形像素以及DGIndex
Talent.NET@2006-06-22 20:00
1:請問如何製作非正方形像素的視頻?例如MS官方網站上面的1080p WMVHD試看短篇就是1440 x 1080的分辨率,但是播放起來卻是16:9
2:請問新版本DGIndex的Video > Field Operation中的兩個新選項
Honor Pulldown Flags和Ignore Pulldown Flags是什麽意思?
請高手賜教,THX

Honor Pulldown Flags - The pulldown flags (if any) are obeyed and the fields are repeated. This means that the frame-served video will appear exactly as it is intended to appear on the final display device. Therefore, if you have a 3:2 pulled-down clip, you'll get the standard repeating pattern of 3 progressive frames followed by 2 interlaced frames. If you have PAL or MPEG1, you'll just get the encoded pictures with no repeated fields (because PAL and MPEG1 have no RFF flags to honor). The frame rate will always be the same as the display frame rate of the source.
Ignore Pulldown Flags - The pulldown flags are ignored. This allows one to obtain the raw encoded MPEG pictures, with no repeated fields. However, because repeated fields intended for display are ignored and not displayed, the resulting frame rate may differ from the source frame rate. It may even vary throughout the clip, due to irregular patterns of pulldown flags. If the pulldown is irregular, use of this option will cause the audio-video sync to change at different parts of the clip, and most likely sync will not be acceptable. This option is mostly intended for power users, who would use it as a diagnostic aid for inspecting the encoded MPEG pictures. Although this option ignores the flags, they are still stored in the D2V file although DGDecode will also ignore them.
多留意下同目录带的指南Manual，详尽的说
