Twixtor-like (super) slow motion for free Updated info Feb11/2012


http://vimeo.com/35410369

This is a Slow Motion & Super Slo Mo rendering comparison. I put this quick comparison video together using all free software and minimal previous experience. I came across tutorials online. I think that the results are pretty impressive, considering the complex scene.

I used Windows Live Movie Maker 2011, MPEG Streamclip, VirtualDub with FFDShow, AVISynth and MSU Frame Rate Conversion Filter, Notebook Text Editor.

really like this, i recall the last land board vid it popped up here on, really dense finish.

the smaller framing with 60fps is only files that work well with this?

lower res and slower 30fps will come out smooth? quite a bit to learn there for me.

if i get a some spotter hand held shot sessions, it would def be worth it.

I was surprised at how simple it all was.

This is the tutorial I used for the 4 frames...


This is the other one that inspired me to try the 15 frames...


You can use any value (within reason) to add the extra frames between frames or combine this effect with the slow mo effect in your editor to get the desired effect. See some of the combo's in my video.

The only hurdle I had was figuring out how to get the right codec in FFDShow turned on so that VDub could work with the file. The error in VDub gave me the hint to solve this.

Twixtor has a lot of "do's and don'ts" to get the most out of it. I think these would also apply to this method. I have seen some amazingly terrible examples of this method and Twixtor. If you look closely at my demo vid You will see that I was likely in violation of some don'ts. How to get the most out of Twixtor

Don't over do it with any effect in your movies. Best to add an effect if it will add to the ''vibe" of the movie. Too much and it's just too busy.

I can't wait to try filming a shooting bullet through an apple :yes: :tumble:

Added some info to tutorial Feb11 /2012


I answered some questions recently and thought I would add my responses here...

I have the HD1 and shoot at 720@60fps. This method supposedly works with 30fps but I think the more fps it has to work with the better.

Unfortunately, this method only applies the filter to the entire clip. There are ways to apply the filter to a range of frames with other filters scripts, but trying them out on this filter did not work. I haven’t been able to figure that out. So, if you only want to do slow mo on a smaller segment of a clip you will need to start by using a small clip and spliting the clip into 3 smaller segments. One for the begining, one to apply the slow mo filter to (by following the tutorial), and one to finish. You can do this in your editor or in MPEG Streamclip.

Also, you will need to convert the clip to .AVI that you want to apply the slow mo filter to before it will work in VirtualDub. You can use MPEG Streamclip to do this too.

Then, follow the tutorial to apply the slow mo. If your editor has the ability to also do slow mo you can use that to tweek the clip for the desired effect. But using this method only may produce the results your looking for.

Adding all 3 clips back together in your editor should make everything look seamless.

these are the recommended download links...

http://virtualdub.sourceforge.net/
http://ffdshow-tryout.sourceforge.net/
http://avisynth.org/mediawiki/Main_Page
http://compression.ru/video/frame_rate_conversion/index_en_m...
Some may be available as 64bit but use all 32bit so all stay compatible. The 32bit software will work on 64bit systems.

There are no other settings that I have come across with this method. I can not say for sure, it's all pretty new to me too.

If you get poor results...

Make sure the the fps in the original footage is kept after you converted it to .avi. The more fps in the original the better.

Perhaps another setting in the conversion process affected the clip (i.e. selecting de-interlace when these clips should be "progressive"???).

Perhaps trying other combinations by changing the value to lower or add frames or possibly add some slow mo to it in your editor too (if it has the ability).

It just may be that your footage may violate some key shooting guidelines. Take a look at this from the guys at Twixtor to see if you could have shot it better... How to get the most out of Twixtor
You can see that their list is extensive.

It is a round-a-bout way to do it compared to Twixtor and you will not know the results until you try it. Reading the Twixtor guidlines might give you an idea whether things will work out or not.

I have not fully explorered this method either. This is all new to me too. But, good results can be achieved with this method and it is free.

Wow- that came out fantastic! Now I don't need a GoPro2 :lol:

Only thing to do now is get up enough skill to do something worth watching in slo-mo :dunno:

zerogee, would you mind elaborating on how you got the right codec turned on?

I came across an error in VDub about the dimensions needing to comform to multiples of 16 (is that the error you received?). I was able to work around this by resizing the video to have dimensions that are a multiple of 16, but I think this might be a sledge hammer for a trim nail :smilegrin:

I'd appreciate any guidance you can offer. Thanks!

I don't remember if that was the same error (I don't think it was). What I do remember is that the error included the name of the codec it needed. So I looked around in FFDShow to see if it was selected and it was not. I think it was in a couple of places too.

Sorry, you might have to Google that error if it does not give you the codec???

I have not had much time to play with it. I did get some good results and some terrible results and some with small quirks in parts of the clip in my experiments. Unfortunately, you don't know until it's done if it worked or not.
