Convert Soft MKV to HARD AVI/MP4 I paying $80 to $120 USD via paypal for the following project. Your Script need to be written in PHP and must be able to run in window server 2008 environment. Basically what i want to do is I have various format of mkv, some is already hardsub and some are softsub. What i need to do is I need your code to make use of command line software available to extract out the subtitle , if the mkv contain subtitle file, if does not contain subtitle file it will continue with the conversion. Your code must convert the mkv with subtitle/ without subtitle to avi/mp4 and the new video file must contain subtitle because the video i download will definitely contain subtitle or already hardsub but i need format in mp4 or avi. Take Note: Audio Sync is a concern and i don't want any audio sync issue. I currently using mencoder for my conversion but sometime it doesn't convert video with subtitle. i know of a setup environment using avisynth and ffmpeg but i am not familar with it. What i need you to provide me is a php code that exec the command line software, all i need to provide is the path to the mkv. If you got no idea where to find mkv file, u can use the address below. More Info on what i do: Basically i trying to convert anime video that is mkv format(soft/hard sub) to avi hardsub or mp4 hardsub What i facing now is that mencoder sometime unable to convert the subtitle properly, i figure out that avisynth could do the job with ffmpeg but i am not sure how to get it setup. If you are an expert in this field, and you got a working solution. Then give me a p.m My payment is ranging from $80 to $120 usd. Payment Mode: Paypal Sorry no advance payment, only pay after job done.
