The OP wants hardsubs, not a soft (switchable) subtitle stream.

warrr147: Adding hardsubs to a video means that you'll have to re-encode the video - and while you can attempt to minimize the damage done by re-encoding, you'll most likely take quite a bit more than a 1% hit in quality.

Actually i want add my logo to the movie , there is no diffrent between add a hardsub for this or add a photo on Corner of the image

a3=Overlay(a1,a2,mask=a2.ShowAlpha())
ReplaceFramesSimple(a1, a3, mappings="[0 299][53999 54299]")
crop( 2, 2, -2, -2)
LanczosResize(1280,544)

Adjust the bitrate to get smaller file size. Use same as your video source to get same size.

[Baldrick]

Click on the Config-button to the right of Encoder settings, increase the Quality settings for lower file size or change the dropdown box to Targeting file size and change the bitrate.

You can check the source video bitrate with MediaInfo.

plz help me!

[Baldrick]

Use mkvextractgui2 to extract the sound from the original mkv and then can you use mkvmergegui to add the sound to the new mkv.

I have no solution for your other questions.
