Keyframe scaling bug

[Cedric Dawnhawk]

For any slide with a non-zero transition time to the subsequent slide, set the "Scale keyframes in objects option". In O&A place a keyframe at the beginning of the transition to the next slide so that it snaps to position (+ appears) Close O&A. Increase (or decrease) the "Display slide for" time. Go back to O&A and the keyframe will have jumped to the end of the timeline (end of transition to next slide). Keyframes placed anywhere else are scaled as expected. This was a bug in 5.5 and is still present in 5.6.1. I haven't checked 5.6.3

Cedric,

You are right! This bug (or is it a feature?) also happens with v 5.6.3.

Apart from this bug, scaling is done relative to the total time the slide is to be seen (display time + transition time) which is the only consistent way of doing it. On the other hand, as the length of the transition time has influence on the scaling, it does not always lead to results which one may expect. I do not consider this feature as very helpful, and I have never used it.

Thanks for confirming the bug is still in v5.6.3. How do I report it officially?

You say "Apart from this bug, scaling is done relative to the total time the slide is to be seen (display time + transition time) ..."

This is not strictly true. With scaling on, set a keyframe at the end of the previous transition, then change the previous transition time. The keyframe remains at the end of the previous transition which is no longer the same percentage of total time. Similarly keyframe at start of next transition/change next transition time.

I agree this feature is probably not very useful so it's all rather academic!

You have placed a keyframe at the "end of slide".

If you change the slide time is it not logical that it should stay at the "end of slide"?

...set the "Scale keyframes in objects option"...

In order that I can offer a considered opinion, could someone tell me where to find this option, please? I have no idea whether I have it turned on or off.

Xaver,

Thanks for pointing me in the right direction! Now that I understand what is supposed to happen I have been able to set up a test project and, I'm sorry to say, everything seems to work OK for me!

I tried to follow Cedric's instructions as follows:

- I created a new project containing just three slides: Black, blue, black (initially all of 4 seconds duration and each with a 1.5 second Fade-in transition)

- "For any slide with a non-zero transition time to the subsequent slide..." - I set slide three to have a Quick transition

- "...set the "Scale keyframes in objects option..." - I did this for slide 2

- "...In O&A place a keyframe at the beginning of the transition to the next slide so that it snaps to position (+ appears)..." - I did this for slide 2

- "...Close O&A..." - I did this

- "...Increase (or decrease) the "Display slide for" time..." - I changed slide 2 to display for 8 seconds

- "...Go back to O&A and the keyframe will have jumped to the end of the timeline (end of transition to next slide)... - It didn't do this it stayed attached to the end of slide 2 as I expected it would.

Unless I have mis-understood Cedric's instructions, there is no bug that I can see!

In order to confirm that scaling was happening I reset slide 2 to four seconds and added a mid-point keyframe (i.e. at offset 2 seconds into slide 2). I then set slide 2 to have 8 seconds duration and checked the keyframes in O&A. The mid-point keyframe was now correctly placed at offset four seconds.

I don't think there is any bug. (All tests done using v5.6.2 - I haven't had time to download v5.6.3 yet)

Peter

Cedric,

From my point of view, this bug has been reported (you did it ).

I think that PTE only scales keypoints which belong to a particular slide, while those belonging to adjacent slides may remain untouched. All in all not a very comfortable affair. I would recommend to avoid this feature.

Cedric,

There are four "magnetic" positions in each slide's timeline: its origin point, the end of the in-bound transition, the end of the slide's duration and the end of its out-bound transition. Any keyframe inserted at one of these points is "magnetically bound" to that event. If you change the in-bound transition duration, the keyframe bound to its end will move with the end. If you change the slides duration, the keyframe associated with that point will remain bound to the event. And if you change the transition duration of the following slide, the keyframe will remain bound to that event. The "scaling" action will apply only to the non-bound keyframes.

regards,

Peter

Peter,

Here is an example!

OK guys, mea culpa!

Now that I have re-read Cedric's post and noted that he said a "non-zero" transition time, I can generate the same condition as you. I agree - it's a bug!

Peter

OK guys, mea culpa ...

Let me express my intention to forgive you
