[FFmpeg-user] getting blured video.

[AMIT KUMAR]

You didn't understand correctly, Carl asked for the complete console
output (a copy/paste of the text) from running the commands.
------------>>> Sorry, i don't have access in my office to use the CMD  so,
that's why i cant send you the console output.I am using through c#
application.

 Does is also look blurry?  ----> Yes.But i need the clear visualization
Mp4.when video creates user mobile have no any EIS features so i think by
ffmpeg can we use EIS features to stop seems hazy or blur effect.

original's resolution is 320x240, it won't look like HD if you scale it up
to 1280x720.   -->> Yes the original file is 320x240, whereas i think if i
scale it into HD then video seems clear so that's why i m using 1280x720.
