Security updates due to FFmpeg (LZ-20 year bug)

Can't think of this happening.... a 20-year-old bug affecting an AV tool...

Since the key file import component, LSmash-Works, use FFmpeg, I have to release an update early.

Please replace the files in the ./Plugin folder

I tried the new version of LSmash-Works and I don't like it. It gave a bunch of errors I can't understand and was very choppy to work with, not as smooth as the older version. So I went back to the old version. My editing system isn't connected to web anyway.

Thank you for the report.
The error was a result of insufficient memory. Possibly due to the extra file support incorporated into my ffmpeg build.
I'll release another trimmed version as default a bit later.

[MaverickTse]

Recompiled.
Please try again.

[racer-x]

Recompiled.
Please try again.

Yes, that one is much better. Nice and smooth editing like before and no errors. Thanks!

DivX/HEVC received an update with 3x acceleration encoding > http://labs.divx.com/divx265

I'm not certain why you're making such post here...but
I'd like to say again: It is too early to make request on x265 support.
The container format standard have just released a few days ago, and eventually which encoder implementation will be dominant is far from clear.

You can directly contact rigaya (via his blog) to request support for DivX's encoder, but personally I do not embrace this motion at this moment.

[MaverickTse]

Is this better than those on page 4?




The large one is 11MB, the small one is 2.4MB, may be can be tweaked further?
(15fps, 150 frames; ImageMagick FloydSteinberg Dither, 0 to 1% fuzz)

The plugin has no options whatever...
(see attached 7z file for the plugin file)

[racer-x]

I tried it out and it works, but is very slow. I tested it against ffmpeg export plugin.

For ffmpeg I used this command:

-vf scale=600:-1:sws_dither=a_dither -r 12 -pix_fmt rgb8 -loop 0

Your new animatedGIF produced file size=5.65 MB. The ffmpeg animatedGIF is 3.13 MB.

1st is new animatedGIF. 2nd is ffmpeg animatedGIF:

Attached below is the source Lagarith.avi if anyone wants to do some testing:

[racer-x]

In this test, your new animatedGIF plugin produces better quality, but it is 2x filesize.

1st is new animatedGIF plugin, 2nd is ffmpeg export plugin:

[MaverickTse]

Encoding Bee.avi with various "fuzz" parameter:

Fuzz Time Size
1% 36s 4.65MB(4,883,520Bytes)
3% 44s 4.65MB(4,877,240Bytes)
5% 45s 4.59MB(4,816,127Bytes)
10% 44s 4.10MB(4,305,312Bytes)
15% 43s 2.74MB(2,881,535Bytes)


5% fuzz


10% fuzz


15% fuzz... serious artifacts

Perhaps I will go with a 5% fuzz value as default...

Tried enabling AVX in ImageMagick libraries, but unable to activate OpenMP on static build... still stuck at 44s mark (1.5fps)

Using dynamic build, GIF export plugin can achieve 2.65fps on the 600x600px image(almost double of static). Yet still very slow.

[poisondeathray]

Awesome thanks for the gif plugin. It's still nice to have several options and user can choose what works best for their scenario

I am new to the "output plugin" thing, so I'm merely stealing other people's code and make modifications (this plugin was actually made 2 years ago but development seems stopped)

To give it a dialog box and save settings like the x26XGUIs... give me time or find someone familiar with C and WinAPI to do it...

The encode speed is really a problem though and I have no confident to solve it myself

Attached the updated (DLL) build with Source Code. See if anyone will be interested working on it.
(Somehow the DLL build crash when closing AviUtl...)

[poisondeathray]

There are probably additional manipulations you can do in imagemagick to optimize the gif, but I have no idea how to optimize or program the dll or plugin for speed or options


OT:
What we need is webpages to start embracing html5, webm to replace animated gif's. Easily 10x lower in size for things like the bee clip above

I've just been to the URL above, and verified that the WebM clip doesn't work without the Javascript f^gg°try -.-

Very-different from the old tags <OBJECT> and <EMBED>, I must say.

I think that free host is using java crap for the ads and buttons. You don't actually need to use java

Technically all you need is to enable webm support (hint, hint, baldrick ), and the usual tags

    <video width="x" height="y" controls autoplay=1 loop=1>
    <source src="PATH/video.webm" type="video/webm">
    Your browser does not support the video tag.
    </video>

Back in the day, there were "unwritten" rules or web etiquette that animated gif's could only be <1MB (or even 100KB if you go way back)

[poisondeathray]

Still OT.....

Java free / Ad free host

[racer-x]

Yes webm............nothing like decent quality at "stupid low" bitrates, the only problem is "stupid slow" encoding. Just for $hits and giggles i encoded a 1080p version of bees to vp9-webm format via the ffmpeg output plugin. Not too bad for 1500 kbps bitrate. I had to change extension to upload.

[El Heggunte]

My bad , now I understand what happened, NoScript was configured to block both <VIDEO> and <AUDIO> stuff.

Which is a somewhat-wise decision BTW, many/most looped animations are rather annoying

Okay, let's (try to) go on-topic again =^.^=

[MaverickTse]

Animated GIF got my attention recently because Twitter added support for it a while back. The unfortunate social reality is that most social platforms do not allow direct posting and displaying of video (videohelp is not alone). So GIF becomes the way to "upload as an image, display as video" sort of trick.

So unless major social platforms support posting of true video files, GIF is going to stay.

[MaverickTse]

Manage to get this out by the end of today... a dithering effect plugin with selectable dither methods (No export function)
DL:
1drv.ms/1mCJKxM

[MaverickTse]

Completely re-written GIF export plugin, with several settings adjustable:

- Looping
- Max color
- dither method (provided by AForge.Net)
- Decimation frequency (the first and the last frames are always preserved)
- Fuzziness (ImageMagick's -fuzz option)

requires .NET Framework 4.5

There are a 2 major bugs for the file posted here, but fixed for the one on OneDrive

[El Heggunte]

requires .NET Framework 4.5

Hmmm, could you please say how-many-percent of the AviUtl stuff require Windows Vista or higher?

And to-be-honest, the last time time I gave a try to AviUtl, it was several years ago ^.^;;

AviUtl itself can run on XP. It is the 3rd-party plugins that may have high spec requirements.

The actively developing Encoder GUIs all requires Win7. Anything that utilize GPU acceleration or AVX instruction sets, requires Win7.(QSVEncode, VCE Encode, NL-Means for GPU, Resize filter-AVX version).

The plugins developed by me ALL requires Win7 (mtDeSub, MotionTracking, GIF Export), because 3rd-party libraries have mostly dropped support for XP.

For older no-longer-develop plugins, most run on XP.

I have stripped out those incompatible plugins with XP and release it as a separate pack.
For Vista... since I don't have Vista machine anymore, I cannot tell anything

[El Heggunte]

^Thanks for answering =^.^=

I asked about Vista, only because the dotNET 4.5 runtime environment requires at least Windows Vista.

I have no objections against the fact that M$ doesn't care about adding new-tech support to Windows XP,
I understand and accept that decision.

But IMNSHO the dotNET virtual machines are a very-bad idea <= clicky.
And considering the fact that the operating system itself DOES NOT run on top of the dotNET frameworks...
...... primarily because these do suck, performance-wise, and also because that would be an absurd idea, .........
...... see what I mean?

That thread in 2001 was nothing but rant...
.NET is not that bad comparing to JAVA.
Of course .NET performance is no match for C, but when it involve building a GUI, using .NET brings a huge convenient than using the old MFC interface.
If there is a C/C++ library with comprehensive dithering or GIF optimization functions, I'll be happy to adopt it in the core code. Otherwise, I have to use .NET library or... writing all core functions myself with C/C++.... which is time consuming and error-prone (I'm not a professional programmer!)

Thanks to poisondeathray's idea of using "SimpleWrapV2" for pagecurl effect, I modified the setting to support 1080p project size. I also figured out how to save settings preset. I made a preset for both left and right pagecurl directions. I'm including it in a zip file. Just copy the folder to Aviutl root. You can rename the folder if you want. They will show up in the "Filter Effects" list.

This effect was created for a 1920x1080 project, but should work on a smaller size as well. It won't work on larger sizes without modifications however. Attached is the zip file and an example video clip:

Nice job.

Yes, I figured out how to save effects presets too when fiddling around... but it's a shame that for the way this is done, it can't be applied generically to all project sizes - I couldn't figure out a way to do that

This effect was created for a 1920x1080 project, but should work on a smaller size as well.

How does it work on smaller project ? Because the way this effect is done, the position numbers are hardcoded, not relative percentages proportional to project size...




Here's an idea - how about starting a resource thread or place where you can download these user made presets in one place. Maybe with a quick gif preview, and a larger video preview download like you have here. Maverick's got plugins stuff hosted, but this is a bit different.

[FaeGiN]

This looks brilliant!!! Thanks for bringing it to my attention. Looks like I'm going to be buried in some project for a while now!

[racer-x]

It works, but it has less flex in the image peeling. The smaller the size, the less flex. I always do my slideshows in 1080p anyway......

Here is an example of my preset on a 640x360 project:
