Properties of a video

See attached picture. Several issues.

1:The video is OK but as you see numbers along the axes are not included. How to fix that? Or how to remove all?

2: The grid is different along all three axes, why?

3: Documentation of VideoWriter writes about many properties of a videoclip, like FrameRate. Where in the code this can be used?

axis([-3 3 -2 2 0 3.5]);
axis equal
grid on

%rest of code not shown

testfilm=VideoWriter('eerstefilm.avi');
open(testfilm);
writeVideo(testfilm,film);
close(testfilm);

Documentation of VideoWriter writes about many properties of a videoclip, like FrameRate. Where in the code this can be used?

Normally, before you open the video.

As for your other questions, it all depends on what film is. I would guess that it may be the result of getframe but you haven't shown that bit.

"Normally, before you open the video." In the Command screen? Somewhere in the code?

The videoclip is fine, and indeed made with getframe

In the Command screen? Somewhere in the code?

It's up to you. If the code you show is in a script, then in that script. E.g. if you wanted to set the frame rate you'd replace:

testfilm=VideoWriter('eerstefilm.avi');
open(testfilm);

by

testfilm=VideoWriter('eerstefilm.avi');
testfilm.FrameRate = 30;    %must be before the call to open
open(testfilm);

Clear, thanks.

Answer 3

I want to set the gridlines of a grid. Mathlab chooses 'nice' limits, but I want to do it myself. I cannot find where. Documentation text:

"axis AUTO returns the axis scaling to its default, automatic

mode where, for each dimension, 'nice' limits are chosen based

on the extents of all line, surface, patch, and image children."

This is the code at the moment:

axis([-3 3 -2 2 0 3.5]);
axis equal
grid on

Has your original question been answered? If so, accept the answer. If not, clarify what the problem is.

If you've got another question then start a new question. And explain better what you want. If you want to change the location of the grid lines, then look at xticks and co. Also see the example: Add grid lines and Edit Placement

OK.

I get this error message, maybe forgot something:

Undefined function 'xticks' for input arguments of type 'double'.
