Ah, thanks, I was put off by the author's original guide, he wrote there:
"Deshaker works best for video shot using high shutter speeds (at least 1/200 sec or so). Otherwise you might get motion blur without motion in the deshaked video. Also, the matching will work better." I need it to stabilize ANIME - should I still give it a try? |

Great. I'll look into it
Addendum: Another thing, I've messed slightly around with the Virtualdub filter plugin and Deshaker in avisynth. Is it possible to set the nessesary parameters all inside a script and avoid the vdub step? Depan should be able to read these log files (although I haven't had any success with it yet), would it make any difference, for Depan to do the 2nd pass instead of deshaker?

I wrote a script for the editing program, Sony Vegas. That script communicates with Deshaker through the VirtualDub scripting language. If you want to take a look at what I did, you can download that script here:
http://www.lawrence-arnold.com/Vegas/DeshakerScript.htm The .js portion is the script for Vegas which you can read in Notepad. If you go about 3/4 of the way down in that script you will see the call I make to VirtualDub and will see how I pass parameters into the VirtualDub script. It is a real kludge because the VirtualDub scripting was something that was added as an afterthought and has never really been enhanced or supported. However, the kludge works and I have a lot of happy Vegas users, especially since Deshaker actually works better than most of the commercial solutions. |

After you run the "deshake.exe" file (which is just a zip file), this will put all the files in the c:\deshake directory. That is all it does (no registry changes or anything else). As soon as the files are unzipped, immediately open the readme.txt file. It will tell you (I think) everything you need to know for your purposes.

Since this is the Depan-thread, I would really like to know how i'm able to load (and save) a log-file as described in on the web page.
It's interresting, if i'm able to scan the video with eigher Depan and Deshaker, but use Depan only for stabilizing the image, especially if i'm able to make corrections to the log-file. |

odyssey, syntax is simple as it can be:
DePanStabilize (source, data=source, ..., inputlog="deshaker.log") So, you are able to read (at last old Deshaker 1.x versions - i did not test recent). But log file does not contain "stabilized" data. It contains estimated motiion data only. so, you cant change intrenal stabilization algo

Got it
At which stage is the BASE frame detected? I have trouble with some scenes where it cannot find a BASE frame and just counts on, and other scenes where a BASE frame is picked too often. It seems like the log file contains just cordinates, but they are not equal to the cordinates displayed with info=true. It would be great if I were able to get a pretty good estimation logged and are able to edit out a few wrongs manually. This is the intro of one of the old disney shorts i'm working on, and I'd assume it's an easy task for any image stabilizer as no elements in the picture are not moving (just the film). Still I have problems with the duck-image and the title, where BASE frame is simply ignored and no correction made. |

I have tried depan very little but here is ( IMHO ) a great way to convert 50i footage to look like it has been shot at 15 fps, "silent film"/super-8 -style.
input = input.nnedi() vectors = depanestimate(input) input_1_of_12 = input.duplicateframe(0) input_2_of_12 = input.depan(vectors,offset= 1./12.,mirror=15,blur=35) input_3_of_12 = input.depan(vectors,offset= 2./12.,mirror=15,blur=35) input_4_of_12 = input.depan(vectors,offset= 3./12.,mirror=15,blur=35) input_5_of_12 = input.depan(vectors,offset= 4./12.,mirror=15,blur=35) input_6_of_12 = input.depan(vectors,offset= 5./12.,mirror=15,blur=35) input_7_of_12 = input.depan(vectors,offset= 6./12.,mirror=15,blur=35) input_8_of_12 = input.depan(vectors,offset= 7./12.,mirror=15,blur=35) input_9_of_12 = input.depan(vectors,offset= 8./12.,mirror=15,blur=35) input_10_of_12 = input.depan(vectors,offset= 9./12.,mirror=15,blur=35) input_11_of_12 = input.depan(vectors,offset=10./12.,mirror=15,blur=35) input_12_of_12 = input.depan(vectors,offset=11./12.,mirror=15,blur=35) interleave(input_1_of_12,input_2_of_12,input_3_of_12,input_4_of_12,input_5_of_12,input_6_of_12, \ input_7_of_12,input_8_of_12,input_9_of_12,input_10_of_12,input_11_of_12,input_12_of_12) ChangeFPS(15,linear=false) assumefps(25,true) I have not seen any artifacts when using this script, very cool! Edit: mostly silent film was shot at 16 fps rather than 15 but it has occured. |

That's a great script. Now if only someone could post one that would do a good job of taking 30p video taken with the "movie" function on still cams, and turn it into decent 60i. I've tried various things with mvtools (which may or may not be a better tool for this than DePan), but so far have not gotten consisten results.

Setting it to an insanely high value (say 100) makes the picture shake around randomly with insane correction values - Why is that? Regardless of any value I put, the duck-image is not detected as a scene - Why not? |

I can not use megaupload in Russia.
My internet is not cheap (about 1 USD per 10 MB). So, I do no know nothing about your "duck" As I wrote above, DepaStabilize was designed not for movie, but for camcorder video. Try apply DePanstimate on cropped border only of your films if it present and stabilize whole frame. Try watch "trust" values and scenedetection. |
