Edit Font size in avi file...

[danielgk]

Hello, I have a movie with subtitles already burned into it. The video file is avi format, xvid.
The problem is the subtitles are too small, and since it is burned in already, i cannot just increase the font size through a video player. Is there a way that I can increase the font size of the subtitles in the video file, without ripping the subs and editing the the sub file, and then re-encoding the video file with the new subs?
I hate using vdubmod for encoding a subtitle in a vid since you reduce the quality of the video (especially since you cant, or at least to my knowledge, re-encode with xvid). And using autogk takes a long time...
So Is there any way to increase the font size of the subtitles without ripping the subtitles out and doing all the stuff i just mentioned above?

If they are burned in, they are burned in, and can neither be changed nor ripped.
If they are a separate stream in the AVI, you can take ut the stream and replace it with a stream with subtitles more to your liking.

the subtitles were added in via autogk, by adding in external subs to the video file, so would that be considered burned into the video or a separate stream?

Ok so how would i go about increasing the font size of subtitles that are in a separate file.
I have subtitles that are in srt format... from what i have read you cannot edit the font in srt format. Can someone tell me the formats that you can edit font size, and which is the "best" format to have subtitles in. Also what programs would i need to convert to the right format, and to edit the font size.
I would be using autogk to put the subtitles in the video files, since from my experience, the video quality and overall quality of the video is not reduced at all with autogk, whereas vdubmod the quality is reduced.
Thanks again.

I think we have to start from the start:
What was your source material? (What did you feed into AutoGK?)
(AutoGK does no magic you can't do with Virtualdub - So, each pass thru AutoGK will reduce quality, just like a "manual" reencoding pass using VirtualDub. That you find AutoGK does a better job, is because AutoGK is better at configuring the codec than the average user)

Open the AVI in VDubMod. Scroll around. If you see subs, they're burned in and nothing can be done. If you don't see subs, then they're not burned in.

If you want larger subs, and if you have a copy of the subs, then you can make them larger and burn them in over the top of the current ones. This will require reencoding yet again.

Oh, Mats beat me.

for autogk i selected the video file (avi), then i selected the subtitle (srt) as an external subtitle to put into the movie (i guess it is burned into the video).

Then i selected the output size and all that, and started the job.

But since I still have the source video with no subtitles added, and the original subtitle file in srt format, i can redo this as many times as needed.

Basically it appears that the first try i did i cannot fix, since the subtitles are burned into the video file, therefore i cannot increase the font size.

So if any of you can tell me the steps i need to take to increase the font size of the subtitles i would greatly appreciate it. I can just modify the subtitles, and then re-encode them into the video file separately.

Thanks again.

You're right in thinking you can't adjust the font size when you have SRT subs. You can make them larger using SSA subs.

Open your SRT subs in SubResynch. It comes with the VobSub package. Save as SSA. Open the resulting SSA subtitle in Notepad. Near the top you'll see:

Style: Default,Tahoma,80,12500670,12303291,12171705,0,0,0,1,2,2,2,30,30,80 ,0,0

The boldfaced number after the font name is where you change the size. If 50 is too small:

then change it to 80 (or whatever you like):

Test them before encoding them into the video. Remove the SRT subs, name the SSA subs the same as the movie, play the movie and check if the size, font, color, positioning, etc., is to your liking. You shouldn't have any trouble telling the larger SSA subs from the smaller burned in SRT subs.

Not sure what subtitle formats AutoGK accepts as external subs - Do you?

With AutoGK can you easily add permanent / embedded subtitles into a video file and encode it to AVI DivX or XviD. AutoGK supports AVI, MPG, DVD, TS input video files and srt, ssa, sub, vobsub idx/sub subtitle formats.

There you are - Convert to .ssa, change font size, and reencode.
