adding watermark as a subtitle

[zammil]

Hi friends,

I want to add a watermark on the right hand bottom of the video.I'm planning to save watermark as a subtitle and embed it using Xvid4psp.i used the SSA syntax([V4 Styles]) and modified it so that watermark can be placed on the right hand bottom of the video.but my efforts are in vain .i cannot get it to place on that specific position.i want to do this way only coz Xvid4psp supports all formats and very easy to embed it .can anyone plz give me the styles to place it at the right hand bottom.any help will be appreciated.

The SSA syntax which i'm using is given below

ScriptType: v4.00
Collisions: Normal
PlayResX: 384
PlayResY: 288
Timer: 100.0000

[V4 Styles]
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, TertiaryColour, BackColour, Bold, Italic, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, AlphaLevel, Encoding
Style: Default,Arial,25,12632256,8026746,12632256,-2147483640,0,0,1,2,0,2,20,20,20,0,0

[Events]
Format: Marked, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text
Dialogue: Marked=0,0:00:05.27,0:00:10.27,Default,,0000,0000, 0000,,WATERMARK

not familiar with ssa format but you can use avisynth to do that:

http://avisynth.org/mediawiki/Subtitle

AviSource("video.avi")
Subtitle("Hello world!", font="georgia", size=24, text_color=$ff0000, align=3)

Change MarginL, MarginR, MarginV values

http://avisynth.org.ru/docs/english/externalfilters/vsfilter.htm

MarginL. This defines the Left Margin in pixels. It is the distance from the left-hand edge of the screen.The three onscreen margins (MarginL, MarginR, MarginV) define areas in which the subtitle text will be displayed.
MarginR. This defines the Right Margin in pixels. It is the distance from the right-hand edge of the screen. The three onscreen margins (MarginL, MarginR, MarginV) define areas in which the subtitle text will be displayed.
MarginV. This defines the vertical Left Margin in pixels.
For a subtitle, it is the distance from the bottom of the screen.
For a toptitle, it is the distance from the top of the screen.
For a midtitle, the value is ignored - the text will be vertically centred

You might find aegisub useful for editing SSA or ASS subs , there are tutorials and guides for it as well

Thanks poisondeathray for ur information.but how can i find the pixel values of MarginL, MarginR, MarginV at the bottom .can u give me that values .tried aegisub but very confusing.

[ricardouk]

you can use vdub to find the values, but if you're going to use a single line in your watermark avisynth aproach is a lot simpler, create the avs with the example above and convert it with xvid4psp, you can "fine tune" the watermark position as well.

thanks ricardouk.i tried it ur way the watermark is coming at the right bottom but it is lifted upwards. u said u can fine tune it but how?.installed vdub and opened the video file but don't know how to find the pixel values .maybe it's very easy but i don't know how to do it.hoping for ur reply.

[ricardouk]

what do you mean with lifted upwards? here´s one example:

[zammil]

i loaded ur given script and get the following error:
Script error:Subtitle does not have a named argument "align"

I guess u r looking for ready to eat dish, but it always better to cook per own taste.
it's 100% sure shot possible with AVISynth Scripting as said by other members as above.
Read AVISynth Help documentation and there is a detailed another thread here on Video Help.
