Hello, Is there any way to reduce the avi file after adding subtitle into a avi file? In the way that original 700mb avi file w/o subtitle can remain 700mb avi file w subtitle. The subtitle file extension is .srt And how to prevent the audio from lagging behind the video? I am now using VirtualDubMod1.5.10.2. So please help mi... Thank you..
I assume by adding you mean hard encoding? To make it smaller you just need to use a lower average bitrate than the orignal. Subs however are hard to compress, add to that the fact that you are re-encoding a lossy format to a lossy format and the quality is going to drop. VirtualDubMod supports VBR mp3 audio so the audio sync should be fine when set to the default direct streaming.
So what is ur suggestion for using any software to get the best result.. instead of using VirtualDubMod? I am a newbie to video editing..
For best results leave the video as is and don't hard encode subs. For hard encoding subs you should get better quality by using AVISynt instead of VDub since VDub requires you convert to RGB24. You can still use VDubMod to encode, you just get to set it to fast recompress instead of full processing.
