Post Deshaking... help!
Hi all!

I started to do timelapse two mounts ago,
and now the first my problem is deshaking rotate shots.

I used filter 'deshaker' in virtual dub

I changed some settings, but the video is too much shake


What program do you use for deshaking and what settings in it?


There are some examples:

I really wanted to do it without any shake!
How can I do it?


Sorry for my English :)


Thanks

I'm afraid you can't make this footage really smooth. The problem is that you are using a wide angle lens that gives fairly heavy distortion along the edges, and so the objects along the edges are distorted differently from frame to frame depending on just how close they were to the edge for each shot. I suspect that's the main reason why Deshaker can't do better. Expensive software like After Effects may help somewhat, but in the end it won't be perfectly smooth anyway.

If you really want smooth panning shots you'll need something to automatically rotate the camera. You may have noticed that Milapse and Merlin motorized mounts are popular and not way expensive. There are cheaper ways though if you are the creative type, people have done it by mounting cameras on egg timers and clocks...

Thank you for your reply!

I have After Effects cs4, so how to use 'Stabilize Motion' in it?

what do you think, may be i can correct distortion along the edges in Lightroom, and then deshaker will be work better?

I turned the camera every 4 shots exactly on one degree, may be it is possible to correct a log-file from deshaker?

You could add motion tracking then stabilize in batches, but it would be a huge amount of work with a tracking shot that has things moving out of frame constantly. AE is stabilization designed to track objects within the frame.
For this type of shot you really need to splash out and buy a telescope head.

It is possible that applying lens distortion correction to the individual images will help, but I doubt you will be able to get that footage really smooth. If you want to see what After Effects can do for you - which could well prove to be useful to you in the future - here are a couple of links to get you started:

Thank you for your advices!

But I have a problem with footage which was made with not wide angle lens.

In this footage i used 50mm lens.

Why this footage is so fuzzy?

am I understanding you correctly - you shoot 4 frames and then pan 1 degree? This could cause the jitters. Can you move 1/4º every shot? or even 1/8º? the 6º a second seems a bit fast.

Yes, you understand me correctly!
But how can I move 1/4º or 1/8 every shot?

In that video the pan appears to be okay (or at least much better), but there is a problem with frames blending with each other which must be caused by some filter or effect you've applied. What software/filter/effects did you use?

I used only deshaker in virtual dub, and changed video speed in Adobe Premiere Pro to 150%

What does the video look like before the 150% speed change? I suspect that's what causes the frame mixing and "blurs" the video. Personally I don't think you need to speed it up either, the pan is fast enough as is.
