How to add permanent subtitle to a video without compression

[LFGringo]

Hi,
Lately I have research in the web for a program that it join subtitles in a AVI file without compressing again the file, than already it is compressed...
Already use the virtualdubmod, but this one only add the subtitles in full processing mode, and encode more the file, what make to lose much quality...
I try the AviSubtitler too, but that make a large and stranger file, dont work properly, and dont find more options in the web from my problem...
Someone can help me?!?

Thanks

Hi LFGringo,

Welcome to the forums.

Click on "How To... All Guides" to the left, and on the new page, in the "How To category" (fourth one down), select " -How to add subtitles to a video" under the "EDIT" heading.

There's 10 guides using different tools - one might be of use.

Good luck!

Hi daamon, thanks for the welcome,
I already saw the guides, but in all, the video is compressed... And i dont want compress again the video or change format , only add the subtitles, no change the video quality...

Thx

Hi LFGringo,

There are ways when using VirtualDub (and probably VirtualDubMod) where you can process video without compressing it - I would imagine that this would extend to adding subtitles.

As it's AVI, you'll be OK using VirtualDub. In that, select "Direct Stream Copy" under "Video" and filter in your subtitles then try saving. The "Direct Stream Copy" does exactly that - directly copies the stream without compressing it, but should filter in your subtitles too.



It's been a long time since I tinkered with subs in VirtualDub, so I may not be absolutely accurate, but I think I'm close enough...

Hope that helps.

Sorry - adding permanent subs to an AVI requires reencoding. No magic in the world will change that.
What can be done is either to live with external subs (most players, both soft and hardware knows how to handle at least some formats) or include them as a stream within the AVI. Unfortunately, this is not as widely supported by players.

What about if the same codec is used in VirtualDub as the AVI was encoded with? Or would that still include re-encoding?

Apologies LFGringo for any misleading info.

Ok,no problem, my idea was create a DVD with 3 or more files in AVI or MPEG, but for that in first needed add the subs to a AVI´s files and then, transform the files to a DVD video with menu...

It was a great idea...

But can be possible without reencode again the files...

Thanks

Hi LFGringo,

You'll need to encode the AVI to MPEG2 if you want to create a video DVD (as opposed to a data DVD with AVIs on).

During authoring, there are authoring tools that allow you to add in subtitles - these are added as a seperate file and not encoded into the video, and so there's no further (re)encoding.

DVDLab and DVDLab Pro is one of these tools.

No, no no! You're holding the wrong end of the stick! DVD is best created by separating all components, and bring them together as a last step - during authoring.
Let's say you start with AVI with MP3 audio and separate srt subtitles:
Load AVI in Goldwave, save wav. Convert to ac3 with ffmpeggui.
Encode AVI video only to DVD specs m2v (many mpeg encoders to choose from).
Author with DVD-Lab Pro, DVDAuthorGUI or GUI for DVDAuthor using your m2v, ac3 and .srt as source files.
Done - a video DVD with "real" selectable subs.

If you're going to do a 3 movie DVD, just repeat the two first steps for each AVI, and bring them all together at the authoring stage.

Doesn't matter one bit, I'm afraid.

OK, thanks. It's been a while and I wasn't sure... Also:

Load AVI in Goldwave, save wav. Convert to ac3 with ffmpeggui.

I believe, and I'm sure I've done it, that you can load up the AVI in ffmpeggui directly and it'll encode to AC3 from the audio in the AVI - no need to save out to a WAV file. Hopefully returning the favour...
