问题 I'm using VirtualDub and I want to digitalize a VHS movie frame by frame. But I need a codec which supports intra-frames. Do the following codecs supports intra-frame? If not where can I get or buy a codec with intra-frame? 回答1: From your current choices: Lagarith may be ok Xvid can be set to intra mode but this is somewhat pointless. There is a lot of better free codecs. utvideo and magicyuv are excellent lossless intra codecs. cineform is very good lossy intra codec but somewhat more

问题 I want to overlay multiple images on my video at different times. I have user function defined as function myFunction(clip c, int coordinateX, int from, int to) { c = c.trim(0, from-1) + c.trim(from, to).Overlay(myImage, x=coordinateX, y=667, mask=myImageMask, opacity=1) + c.trim(to+1, 0) return c } which essentially takes myImage image and place it on specific part of the clip. I call my function as video = video.myFunction(320, 1, 187) and I have bunch of those like this (I'm trying to make

Adjust hue/angle without affecting luminance of YUV image

问题 I am writing a VirtualDub plug-in where there's a requirement to change hue/chroma of image without affecting luminance. Here's some code: Pixel32 *dst= fa->dst.data; int U= (*dst>>16) & 0xff; int Y= (*dst>> 8) & 0xff; int V= (*dst ) & 0xff; Before converting to RGB, I need to adjust the hue of UV by x angle. UV range is between -0.5 and +0.5. Is there a conversion table/formula/already-written-function to adjust, say, hue, by -45 degrees in the colour space? 来源： https://stackoverflow.com

WinRAR的操作 注意：下面各个截图都必须要有个人信息 1、卸载WinRAR 2、在网络上搜索WinRAR，必须是进入官网下载，下面网址我已经抹掉。截图如下： 3、下载到本地后把软件文件的名称加上自己的名称。 4、安装软件，截图如下： 5、在C盘新建一个文件夹，文件夹的名称是考生姓名，文件夹内新建一个Word文档，word文档名称是考生姓名。然后把这个文件夹做成压缩包。 将上面的压缩包解压到“考生姓名02”文件夹内，下面要截图两张，依次是： 0 ***********************************************另外一题分隔符************************************************************ 下载使用VirtualDub裁剪视频,下面有多少张图，考生就要上传多少张图。由于VirtualDub这个软件基本过时了，所以我们做视频编辑换成其他的软件，比如爱剪辑，下面只是做资源下载的练习。 1、互联网搜索VirtualDub官网，进入官网，点击Dowload 2、进入下载链接 选择合适的版本 在下一个页面选择存储路径 2、安装软件，这个只需要解压即可 双击VirtualDub.exe 可以启动程序即可，启动截图如下： **********************************************
