Karaoke Subtitle Encode Problem
Hi, everyone!
I'm working with a karaoke ASS subtitle file with particle effect code(file size: 100MB+). What I want to do is to hardsub the MV. So I write the following code: Code:
Loadplugin("D:\Program Files\megui_svn\VSFilter.dll") Directshowsource("E:\mv.mp4") textsub("E:\mv.ass") CPU:i5-2450M RAM:8G DDR3 Windows 7 x64 Ultimate 6.1.7601 media info(sorry I don't have an English version): 文件格式 : AVC 文件格式/信息 : Advanced Video Codec 格式简介 : High@L3.1 格式设置, CABAC : yes 格式设置, ReFrames : 1 frame 编码设置ID : avc1 编码设置ID/信息 : Advanced Video Coding 长度 : 3分 32秒 码率 : 2 243 Kbps 最大码率 : 3 749 Kbps 画面宽度 : 1 280像素 画面高度 : 720像素 画面比例 : 16:9 帧率模式 : 恒定 帧率 : 24.000 fps 色彩空间 : YUV 色度抽样 : 4:2:0 位深度 : 8位 扫描方式 : 逐行扫描 bits/(pixel*frame)(数据密度) : 0.101 大小 : 56.7 MiB (92%) What slows down the speed? directshowsource, textsub, or both? I tried to google and it is suggested that use ffmpeg import plugin and assrender for sub. Any thoughts, Any help? Thanks in advance! Last edited by pyrobooby; 30th April 2013 at 08:00.

First you should use FFMS2. It's frame accurate and more stable than DSS.
The slow down problem you encountered because of karaoke effect. You could try xy-VSFilter or AssRender to speed up thing a bit. Note that AssRender is a C plugin so you need to use LoadCPlugin(path\to\assrender.dll) to load it.
