The FXScript Reference

Joe, it's fantastic to see this up and running. An awful lot of work, so thanks very much.

Two thoughts immediately spring to mind. Seems like a forum would be a great idea... Also I'd REALLY like to see the ability to alphabetically list all the functions on the same page. I spend an awful lot of time flicking backwards and forwards through the Apple FXScript manual trying to locate a particular function when I know what it's called.

and onto the bug: Your NumToString listing has a typo in it

says "strong" instead of "string". I was thinking "I don't remember that parameter when using it before" ;-)

Just for your amusement, I've only just realised what the image is that you use for Joe's Filters. I always thought it was one of those paper muffin cases (never questioning the connection!) but it has only just dawned on me what the image REALLY is! DOH!

Thanks Martin, typo in NumToString is fixed. An index page listing all functions will be online soon, probably tonight. A forum will be coming in the future.

I've been reading your article on joemaller.com where you explain RGB and YUV. It gave me a good insight and it was interesting to learn the reason for inventing YUV.

I then went to the new site and looked for the same article. This article has been truncated compared to the original.

Joe,

From a newbie, i'm absolutely lost on your new website.
The old one had introductory pages and entire sections devored
to programming in FXbuilder. This new site is nothing more
than a giant glossary . bleh :(

I agree, altough i never saw the old website. this website is nothing more then a giant glossary.
I too want some information about fxscript, how does it work, why do i see the filter working in fxbuilder but nothing when i render the video with my own filter.
Also i can use some indepth info about source and destination.

Sorry if the new site seems overwhelming at first, lots more information will come in time. I'm only one person and with the exception of a few occasional donations, I'm not getting paid anything to do this. I only have so much time and lately I've been working on filters more than anything else.

The idea behind this site is that it will get better with time. A few other FXScript experts have left comments and as more people add to the site, the better it will get.

That said, I'm planning to move my introductory articles over to this site as soon as I get the time.

Excuse for the very bad English.
Thanks for the job that you have made in order to create a guide online.

You know that there are not written and explains to you commandos of "FXScript" on the handbook?
Like "getTextLine(string, i, sub-string)"

still thanks

Joe, I've said it before, I think your work is brilliant and this site is further evidence. Every so often I dip my toe into FXScript and every time get a bit closer to doing something useful, thanks to your rigorous explanations of an arcane art. And nice work with CSS and the database stuff here. Keep it up.

Now to fix the Broadcast Safe filter...

This is a test and an announcement.

I am trying to render uncompressed a 7 min. FCP project and I get the error: FXScript Divide by 0. This project has many filters, transitions and special effects on text generated within FCP - I have not written any FXScript for my effects. It also has about 8 video track layers. I am sending it at 29.97 fps, NTSC anamorphic. I have also tried sending directly to compressor using 2 pass VBR 6.2-7.5 mbps but get the error message: Quicktime Error 0. The strange thing is it will let me compress a Sorenson version for the web. I have tried the same process on another G5 but got the same results. Any insight would be greatly appreciated.

Thank you,
James

When drawing to an image can you do the following?

image[x][y] = color ??

It keeps coming back at me with the error out of bounds. I'm pretty sure the image is declared with appropriate boundaries. ie.
image name[w][h] etc

Ultimately I would like to paint to an image per pixel, ie the opposite of ColorOf. Is there a way to do this, or am I just insane :}

Ian.

I've been wanting that for four years. Even just being able to read one index of an image array would be wonderful. Try sending this to Apple's FCP Feedback page, link's at the top.

I would also be able to use a SetPixel[x][y] command, or even being able to use a GetPixel[x][y] in a "if" statement or a "while" loop...

I suppose if you really have to draw a pixel you can use a line function with the start and end points identical. Really inefficient because FCP would do anti-aliasing on the line.
