Pete, thanks a lot for your efforts!

Right now I don’t have the time to download and install CS3.
But I will do that in the next days and have a look at your project file. For now I came up with decent results by adding more contrast to the video, then precomping it and afterwards applying the stabilization. It’s looking ok considering the footage quality. I will leave it now as it is. But maybe you can briefly tell me what you did in order to stabilize it?

Thanks again!

I can’t open the file…I still use AE 7.0 Pro and you created the project with CS3 I suppose. Is there a way to open the file anyway?

In case queueing at megaupload takes too long:

Ok hwg again…now DV compressed:

I don’t have access to the original DV files. They are in the university. I exported from AVID uncompressed to now do some post work in AE.

Anyway, I have high contrasting points, but they are not sharp, because the footage was shot during sunset and is generally of low quality. Also I interpreted the footage correctly. But I will try to space the tracker points more far apart. Can’t do it right now…rendering stuff.

Tx.

Thanks for the tipps! But my problem is that the rotation is not eliminated with AE’s motion stabilizer. I know that I have to scale up the footage afterwards, but I wish I was so far 😉 Still having this annoying rotation that I can’t get rid of 🙁

[Conseannery]

Yes I understand what motion stabilization does.

As I said I don’t have unwanted motion from side to side, but along the optical axis.

I pick two tracking points in the video that should be stationary. AE analyzes them and then puts the keyframe into the Rotation channel of the video. The video now is cropped to accomodate for the rotation, but it still rotates along the optical axis which it shouldn’t do after applying the tracking data, right?
My guess is that the poor video quality makes it hard for AE to properly analyze the footage although the chosen tracking points have a very high contrast (dark on bright yellow background).

I will upload the clip again with a different codec. But still HuffYUV is ideal because it compresses by approx. 1:3 and is lossless. So if anybody of you wants to try the stabilization themselves you need the clip in a lossless format. Are there other more common lossless codecs I could use?

Tx!

[Conseannery]

I have a very annoying rotation along the optical axis in my footage. I want to get rid of it. However, the footage is low quality DV and AE seems to have difficulties getting clean tracking data out of the clip.

I uploaded the HuffYUV 2.1 compressed file at megaupload.com so that you can have a closer look at it in case you have the time.
It’s 169MB.

I would be very thankful if one of you could even try to stabilize it since I just don’t get it done properly. This is bugging me since 2 days.
This short clip is part of a student project and tomorrow is deadline 🙁

Of course any instructions are also highly appeciated 🙂

Thanks a lot guys!!

Hi RoRK,

I just roto-ed the biker and made it a 3D layer.

I then tried to make the particle stream go around the biker in a circular motion, so that it first goes behind the biker and then a couple of frames later goes in front of it again.
Going behind the biker works just fine, but I can’t make the stream go in front of the biker again although I adjusted the Z position that it is clearly in front of the roto-ed layer.

Am I overlooking something?

Tx.

[Conseannery]

Thanks a lot guys!

Btw, I need to rotoscope the bike as well. But I guess you are right, it is not as tedious as I made it.

What is this CC sphere thing you mentioned? A particle generator?
