Controlling Animation on Rotation

[tmnader]

I have animated an object (picture of dolphin) so it rotates in a circle using: motion-rotate 90 to left. The problem is that the first rotate is fast then it goes into the the nice smooth slow rotation that I want making a full circle. I have tried various keying techniques to control the rotation but can not seem to get a handle on the speed of the first intial move. Any advice?

Maybe I am missing something here, but...

Why are you hitting "Rotate 90 degree to left in the first place"? If you want control, initiate the keyframing with Timeline Indicator at desired location and hitting the Toggle Animation Button, and then thereafter move the Timeline Indicator and dial in/or use your cursor to change the values (increasing -) located to the right of that Rotation area of the interface?

I will be looking forward to see how this unravels. Your start with the Rotate 90 degree button seems to be the mis-step in what should be an easy keyframing.

ATR-I may be doing this wrong but let me explain to maybe clarify what I am trying to do.
I have a painted picture of a dolphin that is arched like it is jumping out of the water. The picture is still during the beginning part of the movie, then when the music starts I animate the dolphin to rotate 180 degrees, without the dolphin moving from it's original spot. I am not creating a circle with spatial keying, but rather, flipping the object.

Thanks for the clarification for:

with:

So, all you are doing is keyframing, taking your dolphins and hitting the Rotate to the Left 90 at 4 different times as the video progresses -90, -180,-270, -360 (aka -1x-0.0 degrees). What does the spacing look like in your keyframing?

Assuming that you want to rotate that dolphin in a circle -0 to -360 degrees, try this:
Place your Timeline Indicator where you want the dolphin to move 90 degrees to the left, initiate keyframing, then enter -0 in the rotate dial up.
Take the Timeline Indicator only to where you want the rotation to go full circle (-360 degrees) and enter -360 in the rotate dial up.
See what that looks like without rendering the Timeline and with rendering the Timeline. With either way, do you get the smooth movement that you are seeking?

With the procedure that you are presently using, does rendering the Timeline improve the rotation smoothness?

Am I close to what you are looking for or still miles away?

No matter how this is done the article at videoinasnap by Steve Grisetti is still a good one and very relevant. To create a smooth motion path it is many times necessary to utilize the Bezier tool in Premiere Elements. Just want to mention that in case you need to do some tweaking.

ATR's suggestion about manually changing the Rotation numbers should give you a nice rotation rather than using the 90 degree shortcut.

As they say in French, "d'accord".

ATR,
Sounds like it may work-I will give it a try. I did not try rendering, unless hitting 'apply' means rendering? Still a newbie.
CE,
Thanks for your suggestion as well. I will check it out. The rate of motion is and will be very important in my projects.

In Edit Mode (Orange Tab)
Content on Timeline
if red line running across the top of the Timeline
Render the Timeline content by pressing Enter Key of the computer Main Keyboard
Wait for Rendering process to go to completion...when it does, the red line across the top of the Timeline will turn green

This type of rendering
a. can be time consuming, but essential to get the best possible preview of what the end product will look like
b. does not impact end product quality
c. gives you a window of opportunity to see problems and correct them before you are stuck with end product with glitches...especially with transitions, titles, effects...
d. piles up "a lot of preview fles in the Adobe default folder (My Documents/Adobe/Premiere Elements...on the hard drive.

"d. piles up "a lot of preview fles in the Adobe default folder (My Documents/Adobe/Premiere Elements...on the hard drive."

Does Rendering help or hurt programs performance?
Does Rendering effect editing in anyway?

Rendering the Timeline is if you NEED to get the best possible preview before continuing to the end product. You will get the same quality end product with or without the Rendering of the Timeline as described. But, if there is a problem, especially with titles, effects, and transitions, you will catch it sooner than later by getting the best possible preview in the Edit Mode (Orange Tab). I think I said that before.

There was one time when I was importing VOBs into the program with the Media Downloader. When I got the VOBs on the Timeline, the audio was not quite in sync with the video. After I Rendered the Timeline, the problem was not there.

However, the process can slow down the performance of the computer,
IF
you have a lot of the scratch files (preview, encoding, media cache), not to mention AutoSaves, old project .prel files, piling up in the Adobe Folder located in its default location, My Documents/Adobe/Premiere Elements....
and IF
you do not have enough available RAM and free hard drive space

You can go Edit Menu/Preferences/Scratch Files and for each category browse to a folder on an external hard drive and direct the Scratch Files there.

Rendering the Timeline should not mess up any of your Timeline edits except as noted above with regard to computer performance with too many scratch files on the internal hard drive with not enough resources.

This is going off in another aspect, but, when you get a chance, look into conformed video and audio files that are continually piling up on your hard drive (video ones with .mcdc file extensions; audio with .cfs and .pek file extensions). That is another story for another time.

Will rendering slow or help the program's performance? Besides of course the time it takes to render.

[ATR]

tmnader,

As mentioned previously, Rendering the Timeline can slow the computer performance if the preview files piling up are impacting your computer resources, namely available RAM and free hard drive space, and your computer resources are limited. The computer performance will be reflected in this resource demanding application installed in the computer.

Some have advocated for not Rendering the Timeline and going straight to the burn to disc stage. But, if a title, effect,transition, or non DV AVI content did not look quite right in the Edit Mode, you are taking your chances if you omit the rendering and "assume" that any glitches seen in that area are just a preview issue, not a quality/performance issue.
