--- Quote from: donnyj on February 03, 2005, 08:38:48 pm ---Thank you for mode 4!!!!!  I must have mis-represented myself (no surprise, I do it often).  I meant "like an animated .gif"  Is it possible to do an actual animated gif that big (long)?

I was trying to say that I want a screenshot-sized avi.  I have no desire to play them full-screen etc.

There has gotta be a better codec that takes into account the fact that there is a very limited color count compared to an actual movie.  I believe that AVI is the right container though!  I don't understand how many of the AVIs are bigger than the actual .PNG files???  Shouldn't it just be encoding the changes and a keyframe every so often?

I don't know. Silver may be able to answer that.

Adding -movieaudio 2 should be trivial. I'll do that asap.

I'll probably regret asking, but what FE's work well with the AVIs?

Attract videos are currently supported by 3d Arcade, Mamewah, Dragon King, Kymaera and Ultrastyle. I'm writing my own front end (creatively titled QFront) which will also support the attract videos.

Hi,

Well first thing to remember is that the png's themseleves are all individually compressed. And a lot of older games - with lots of 'black' on the sceen, happen to compress quite well as pngs.

The avis are encoded as a keyframe + changes (IPB frames) and to be honest are designed for more complex media ie films. You will find that some of the more complex hi-res games have larger pngs than avis. (And don't forget the audio too. In almost all cases pngs+wav is bigger than the avi).

Also, you could compress the avis a lot more and they will look fine. Which you can now do with option 4.....

@Buddabing

This may be irrelevant now you have already introduced an option to load the video/audio compression externally.... But just in case:

The newest version of Vdub (1.6.3 - not sure about 1.6.2) can pass some paramaters from the command line into the script. So for example, if you included the line:

VirtualDub.audio.SetSource(VirtualDub.params[0]);

in the script, you can pass the audio filename from the command line:

vdub /i "settings_with_audio.vcf" <audio.wav> /p <in> <out> /r /x

where <in> can be the first png in the sequence and <out> is the avi.

Obviously this does not solve the other issues that require script adjustment, so you are probably best off leaving it as you are now...

The author of Vdub, Avery Lee, kindly informed me of the above.

Hi Silver,

Does he know about the crash when the sequence of uncompressed pngs is used? Was it fixed in 1.6.3?

Some users may want to use uncompressed pngs via -moviecompression 0 -movievideo 0 to generate the highest quality video possible, then compress it themselves later on. As of version 1.6.2, Vdub crashes when this is selected.

Thank you Silver and Buddabing for explaining the technical sides to me!!!
