Animating beyond 999 frames

Way back in the days of the Collaboratory there was a thread http://communities.ptc.com/message/45030#45030 discussing how to get longer animations beyond 999 (or 9999!).

The main point is that the dialog box is sized in one (microsoft) way and the characters being typed in by some (microsoft) font size. As the versions have come and gone the available space for the ### characters has reduced, limiting the animation length.

Unfortunately the pictures have been lost, so I'm wondering if anyone knows the right settings for changing the screen DPI (if this is what is need) to get a bigger dialog box, and also to change the system font that Mathcad is using (to something smaller) so that I can get at least 9999 (four) digits of animation.

Ideally I'd like to be able to animate at regular display DPI, yet get at least 1100 FRAMES (i.e. enter 4 characters in the dialog box)

I'm using V15M030 on XP (home) and on W7 (work).

Re: Animating beyond 999 frames

None of the tricks and tips provided here worked for me.

As Valery wasn't willing or wasn't able to show us how to use negative values of FRAME in a meaningful way, I had to find out by myself.

Its quite easy as its just a matter of two's complement of 32-bit integers. FRAME seems to be created in 32bit two's complement representation but when it comes to Mathcad interpreting it, it is seen as a normal binary number. That means the the MSB (2^31) is seen as positive and not as negative. So its quite simple to use negative FRAME values - you just have to subtract 2^32 if the number is greater than or equal to 2^31. Due to a lack of binary operations I guess we have to resort to an if function or an if statement.

Find attached an animation created with FRAME running from -20 to +20.

This means that as long as you don't need more than 1999 frames you have a solution for animations with more than 1000 frames.

Re: Animating beyond 999 frames

Here is the missing picture which Jean had attached back in 2004.

Not sure if it will help, though.

I am not aware of any trick to get more than 1000 FRAMES but if you have luck, please tell us.

Re: Animating beyond 999 frames

We can use from -999 to 999 frame's numers. But there is one bug at frame < 0 and we must use the if operator by the frame creating.

Re: Animating beyond 999 frames

Open the Option in the Video, and reduce the compression quality and the "temporary compression ratio" in the config, then I can record 9999 of the FRAME. And I can't input more than four figures in the input box.

Unfortunately this does not work for me. And when I look at the compression ratio it always automatically jumps back to 0.75, even if I has set it to 0,1 as adviced by your pictures.

I also tried to change the trick with setting the display foont size to large, but it didn't help either.

Can you please explain how exactly you would use the negative FRAME values?

As you can see in the attached animation where FRAME is set to run from -20 to +20, FRAME has a constant, high value in the first half of the animation.

How can you use the "negative" FRAME values in a meaningful way?

Re: Animating beyond 999 frames

Thanks for finding the image.

Is there a trick to locating these old ones where the link in the original thread doesn't appear to work?

The image was useful in confirming that my experiments were in the right area (relative to the original post), even if it wasn't sucessful!

Re: Animating beyond 999 frames

Zhu, Can you enter a request for 9999, even without it being able to save because of poor compression?

If that is so, it would suggest that the choice of the 'system font' that Mathcad is using affects how much space there is for the character entry (for the FRAME range value).

Re: Animating beyond 999 frames

The -20 to 20 FRAME of mine animation works well. And the 20 to -20 is well too. Video Link : 5433
