Problems using DeshakeR

[Freekers1337]

Hi all !

I’ve been trying to deshake my the clips I shoot on my holiday in Vegas last month, but it just isn’t working out. The footage was shot in ‘Full HD’ 1080i.

The problems I am facing are:

1. The footage is way darker after it’s deshaked
2. The footage is more shakey than it was before !

The Deshaker settings I use are the following:

Pass 1:
Default, but I also tried changing ‘Source pixel aspect’ to HDV without any difference

Pass 2:
Default with ‘edge compensation’ to adaptive + fixed (no borders).

I also tried deinterlacing the footage before deshaking it, but that didn’t help either (to get the shakeyness away).

For your convenience I have uploaded both the deshaked as the original file so you can see the difference… BUT, here’s an interesting thing: When uploaded to youtube, the video isn’t shakey anymore, but still dark ! So, here’s the deshaked clip in .AVI format too:

Any help is well appreciated !

Thanks !

That type of footage is not going to "deshake".

It's constantly changing so there is no way to establish a decent reference grid, and the panning is too fast so there's not enough frames to work with.

Deshaker CAN work on milder shakyness where there is a main subject to "anchor" to. An example might be a baby walking across the room where the baby is always in frame.

Your AVI file was bobbed with the wrong field order. Also, try turning off the rotate and zoom options in deshaker. Frames swapped to correct field order, resized, and deshaked, xvid/mp3 AVI attached. (Oops, forgot to set the pixel aspect ratio in xvid.)

Thanks for both of your replies !

Ok, I did not now that (I'm a newbie when it comes to video editting). Still, I have other footage where there is an main subject to 'anchor' to which gives me the same problems as described in my start post.

Wow that looks great, but it's still darkened ? Or did you use my already darkened .AVI file ?
How can I correct the field order myself ?

Thanks !

I started with your AVI file assuming Youtube would have mangled whatever you uploaded there (I just downloaded the 1080p "original" sample from Youtube and it was 29.97 fps). All I did was fix the frame order, reduce the frame size, and deshake. I made no attempt to adjust the brightness. Did you bob deinterlace in Vegas or VirtualDub? If you used the bob doubler filter in VirtualDub just change the field order setting in that filter. If you did it in Vegas and it doesn't let you switch the field order you'll need to use a different filter or different software.

You should also be aware that most computers won't play 1920x1080p60 video smoothly.

I'd also recommend using a file transfer service rather than Youtube. That way people can see samples of your actual files, not Youtube conversions.

Most will accept 100 to 200 MB files or larger without even signing up for an account.

Thanks again for your reply.

I just did a 'bob deinterlace' in VirtualDub (I don't have Vegas) but I am not sure if I have done it right (I'm new to this) because the problems still remain. What settings should I use ? I tried 'normal' for both as well as 'smooth' but I see no difference at all.

My computer has no issues with playing 1920x1080p60 video smoothly. I have an Core I5 CPU with 4GB of RAM and it plays pretty much every .mkv file I download.

Thanks for the tips regarding file transfers.

I'm not sure which filter you're refering to. The built in Deinterlace Filter has double frame rate options with Top Field First and Bottom Field First. Use whichever is correct for your interlaced source. If you use the wrong one the output will have a 2-steps-forward-one-step-back jerkiness. There's also the internal Bob Doubler filter with both TFF and BFF options.

Where are you finding 1080p60 files (there are only a handful of camcorders that produce that)? Blu-ray rips will usually be 1080p24.

Hey that does look good, I'll have to eat crow and take back my other comment. I never really had good luck with deshaker, and usually end up with "jellovision", but I'm going to revisit it. Thanks.

P.S. Do you have or know where I can find a good tute?

I tried the built in filter, but the same issues still persist. I tried both double frame ratie options (Top Field First and Bottom Field First). Is there also a third party filter available who does the same job ?
A friend of mine told me to have a look at this 'filter pack', containing some popular filters:

Check youtube, it has some pretty decent tuts

I suggest you revisit this. One has to work right. You can view the output window after adding the filter to verify the correct field order. Step through the video field-by-field using the right arrow key.

I don't think so. VirtualDub only recently (about a year ago) added the ability to change frame rates. Other deinterlacers haven't been updated to add this ability, as far as I know.

The first of those is 1080p30 h.264. The second is 1080p60 but uses WVC1 which is easier to decode than h.264. In any case, you can worry about that after you've fixed your field order problem.
