16:9 JES deinterlacer slow motion

I am trying to use JES deinterlacer to slow down a clip but cant seem to get the output in 16:9. I have followed the instructions below and keep checking the 16:9 box but the output is always squashed 4:3. I've tried fiddling with the options and cant seem to find an answer.
Does anyone have any ideas?
From JES instructions.,..
Slow-motion and fast-motion: In JES Deinterlacer's Project tab select "Project kind: Standards conversion". Select "Custom" and set "Movie speed: 0.5" for 0.5x slow-motion, 2 for 2x fast-motion and so on for other speeds. You can select speed ratios in the range of 0.1-10x with 0.01 decimal precision (with v2.7.1 the 0.1x may stall and with 0.2x the audio is out of sync. 0.25-10x are OK). THEN set the other options:
For NTSC use "Settings/Height: 480, Width: 720, Frame rate: 29.97".
For PAL use "Settings/Height: 576, Width: 720, Frame rate: 25".
Check "Blend" and let "Scale only" remain unchecked.
In the Output tab set "Video output/Compressor/Export: DV Stream.../DV Format: DV, Video Format: NTSC/PAL, Scan Mode: Interlaced, Aspect ratio: 4:3/16:9, Audio Format: Unlocked/Locked, Rate: 48.000 kHz".
Let "Progressive (out)" remain unchecked. (Leave the other options as defaults).
Select the output folder via "Put..." and click "OK" to start processing.

I exported the clip as a full quality clip from iMovie5 (had to go back to it after audio trouble importing from my HDR-HC1). I get a .mov file and then use that as an input file for JES. The 'converted' file is a .mov.proj.dv file which looks like a squashed 16:9 in 4:3 window in QT. I tried importing it back into iMovie and it imports as a 4:3 with black side bars - no letterboxing. The project I am working on is a 16:9 HD format.
I havent tried any other exporting yet as I'm fairly sure if they look that way in QT and imovie then that's probably how they are.
I do notice that when I make all the settings in JES, as I outlined in my question post, once I change the aspect ratio to 16:9 and then close that window and open it again, the setting seems to have defaulted back to 4:3. I tried it several times... (Ver 2.7.3 - I think that's the latest)
I really appreciate any advice.

Possible to convert video footage to slow motion?

Long story but I'm filming a short video in the style of the Intel TV ads (link below). Is there a way of converting footage I shoot into slow motion?
Have read discussion threads for other versions of iMovie, but not '08.
Thanks for any advice.

Yes. This feature is built in to iMovie 09, but for iMovie 08, you must pre-process with an external app such as JES DeInterlacer.
If you do a search of this discussion, you will find some posts that link to Karsten Schluter's web site where he gives detailed instructions.

Slow motion jerkiness when rendered to DVD

I've upgraded to iMovie HD 6 and I am working on projects that I started in iMovie 4. This has happened because I am working on 5 or 6 projects at the same time and I have only now got to the point where I want them on DVD.
All slow motion clips look fine in iMovie, but when they are rendered to DVD they are incredibly jerky. BUT, not all of them. This seems ridiculous, if they were all jerky OK, but only some of them.
Does anybody have a solution, or do I have to re-install iMovie 5.
Please don't suggest JSE software as there are far too many clips to be exporting and re-importing.

As a bug, some early iMovie HD version (AFAIR v5)didn't deinterlace slo-mo clips. This produced terrible shaky motion on an interlaced TV if the source material was interlaced.
Later versions fixed this. If this is the case, then you must re-render those clips, re-import and render them or use JES Deinterlacer to deinterlace the shaky clips.

Can i upgrade imovie 08 to something that does slow motion?

can i upgrade imovie 08 to something that does slow motion?

There is also a free app called JES Deinterlacer that can do slow or fast motion outside of iMovie 08.
See this link to Karsten Schlüter's site.

I need to do slow motion, but i have imovie '08 and i cant figure it out. can anyone help???

i cant figure out how to do slow motion in imovie '08 and people are saying that i need to get imovie '06 but i cant find it!!! HELPPPP! i need slow mo!!!!!

The free program JES Deinterlacer has a slow motion (or fast motion) feature. To use this program you will probably need to look at Help in the JES menu. In the window that opens, click on the Project tab. In the lower right you will see a box labelled "Movie speed". If you want half speed type in 0.5000 (representing 50%). For quarter speed use 0.2500, and so forth. For fast motion, 1.500 represents one and a half times speed and so on.
In iMovie, right-click (or control-click) on the clip that you want to slow down, then select Reveal in Finder. In Finder, open the clip with JES and proceed from there (as I said, you may need to look at Help).
The exported clip can then be reimported to your iMovie Event and used in your Project.
JES Deinterlacer can be downloaded from the home page of the developer Jan E. Schotsman:

It is also downloadable from this Apple site (but it's an earlier version):

Slow motion, reverse, and speed up

In iMovie 08, I cannot figure out how to make the video play in slow motion, reverse, or speed up. Is there any way to do this with iMovie 08?

I tried downloading JES Deinterlacer and had a lost url... What to do?
I have no trouble downloading last December's update directly from Jan E. Schotsman's Home Download Page. As to it's use, see if this Quickie Tutorial helps (I have been told it will either put you to sleep or provide enough information to use it):

Where or what else could i use?
QT Pro ($30) also has limited use in changing playback speeds. See these Quickie Tutorials:

Slow motion and iMovie 5

I'm wanting to create a slow motion effect in iMovie 5.0.2. As we all know iMovie's slow motion effect is less than satisfactory (jerky). I've tried using JES Deinterlacer but have run into problems with it. In my research I've come across an iMovie plug-in sold by Partners in Rhyme that claims to create a smooth slow mo effect. Has any one had any experience with this plug-in and is it compatible with iMovie 5? You can see it here: http://www.partnersinrhyme.com/osx_software/TimeEffects1/TimeEffects1.shtml
Thanks!

Hi jayfan:
(I'm an Illini fan...) But, I will still answer you
That plugin is actually one of many offered by Stupendous Software
They are very reputable and it should work great with iMovie 5.

JES Deinterlacer appears to have butchered my movie projects

After converting my jittery slow motion clips in 2 movie projects of mine with the Deinterlacer (spending a few hours in the process) I have found that when I reopen these projects pieces of clips are missing. They reappear in the trash but I cannot reinsert them because transitions have been placed where they used to be. Aargh! Any suggestions?

when I reopen these projects pieces of clips are missing. They reappear in the trash
Make sure the iMovie project volume is formatted as Mac OS Extended. Those symptoms indicate that this is not the case so iMovie can't properly save the project!
Anyway, how did you render the slo-mo clips? I'd use the following workflow:
1. Open the Timeline Movie.mov inside the iMovie project's /Cache folder with JES Deinterlacer (this uses the whole iMovie timeline as input). Or export just the desired clip as Full Quality DV and use it as input. Set JES Deinterlacer settings as desired and set it to output .dv.
2. As a shortcut, you can output the .dv straight to iMovie's /Media folder:
http://www.sjoki.uta.fi/~shmhav/iMovieHD_6_bugs.html#quick_DVimport
Take care to output only pure plain .dv (DV/DVCPRO NTSC or DV PAL) and also take care to use the correct NTSC/PAL video standard with 48 kHz audio. With those precautions, I have not noticed any ill effects with iMovie 1-6. And even if you'd not take those precautions, it should not affect the other clips in the project (wrong kind of clips might have artifacts with added effects or they might not export properly to the camcorder).
But to play it safe, you could output .dv to some other folder and then let iMovie import it as usual.

Hdv with slow motion does flicker

I´m editing now some clips at 1080 i and I need to use some slow motion clips. I use speed at 60 % and also active frame blendding and all it´s ok and I haven´t any trouble with the video. But when I do render I can see a big flicker at the picture. I put some deinterlace or flicker filter and all beccomee good but when I do render another time and export the movie I can see the flicker. The trouble is like final cut can´t apply the filters because if I mark frame blending at speed and save it, when I open fcp another time the effects was not in this place.
Sorry for my English

Maybe it has something to do with HDV? Can you switch your sequence rendering to ProRes? CMD+0 to enter your sequence settings. Click on the Render Control tab. Under Codec, choose Apple ProRes.

Slow motion effect results in an unwanted high pitch sound

whenever i apply the fast/slow/reverse effect to a clip, a high pitch sound is created...how can i get rid of this without extracting the audio of the clip (there is no high pitch prior to applying the slow effect)?

Hi Darin,
... changing the speed of a clip HAS to change the pitch of audio.... have a look at the JES Deinterlacer... it has some nice, elaborate slow-mo effect......

Slow motion problem

I'm using Shake's adaptive re-timing, but when I set the video to anything less than .5 speed (like .33, or .15) the rendered footage looks jerky and jitters back and forth when it interpolates the frames.
I don't think this could be due to the deinterlacing, because it's the same despite what I set the deinterlacing to.

Retiming techniques have their limits. You can get optimal results beetween 0 and 50 percent max (normal speed to half speed). After that limit, the software doesn't have enough informations to reconstruct the huge time gaps between two frames, especially if the footage represents a high speed movement.
Keep in mind that the retiming possibilities are for retiming, not for slow motion, there is no miracle at this point.
For slow motion videos, use high speed cameras. Most DVCproHD cameras have the ability to record at 60fps full frame, that's a good start.
For interlaced video, if you accept to loose image quality on the vertical resolution, the 25i format can be converted in a sort of 50p, that's not bad for low budget projects!

Stuttering slow motion

Everytime I do a slow motion effect is stutters. Any ideas on how to smooth it out?

When you are adjusting the speed make sure that "Frame Blending" is selected.
If that doesn't cure it you could experiment with the Deinterlace and Flicker filters.

Slow motion exporting problems

Hi there I had posted a topic with this same problem a couple of weeks ago and got some great suggestions, but unfortunately have to report that nothing has worked! I have tried deinterlacing, got a plugin from the net which was meant to have smoothed the slow motion, all looks well in the FCP and also in the exported quicktime, so does anyone know why it looks terrible when I watch the dvd back?
an example is that Someone took a photo of the couple I was filming, the flash looks square! And when I moved the camera around while filming, the edges of people look square. Have an idea it may be something to do with pixels, but I dont know what!
I am really at my wits end trying to find solutions and am about ready to fire my mac out the window! Can anyone help and save the mac?

It depends on the formats you import. Are you slowing your footage down -100%? make sure you have constant speed checked. Maybe your time remapping it.

Jes Deinterlacer: when to use it?

I saw a tutorial movie on YTube about slow motion in FCPX. In this movie JES interlacer is used before Retime - Optical flow.
But I saw I can get same result (maybe not just the same?...) directly using Retime in FCPX.
Any advice?

If you're shooting 1080i you may benifit from using jes.
Jes de-interlacer is, as the name implies, a de-interlacing app. And it's a good tool to have around.
If you select "use both fields" in Jes and "double duration", Jes will interprolate each FIELD into a FRAME giveing you a very respectable 50% slomo'd progressive file out of 1080i. You can then slow that even more in FCP, like you saw on YouTube.
I you're already shooting progresive then it's moot. Just use FCP.
Hope that sheds some light.

Slow motion: PPro v After Effects

I'm new to the CS3 products. In previous versions I found After Effects slow motion (time remapping) to be better quality output than PPro slow motion on a clip. Has anyone done a comparison for slow motion in CS3 between PPro and After Effects?

Oh, right on. I hadn't played with Time Warp in Premiere. Yes, I have tried the PPro Time Reampping, but I still find the keyframing really cumbersome. I guess I've been working with After Effects too long for this sort of thing. Can't teach an old dog, eh? I suppose I'll delve into it more deeply when the need arises.
I've been having another issue with Premiere that precludes me from using Time Remapping, Time Warp, Speed, etc: Since I upgraded to CS3, whenever I apply speed changes (of any kind) the clip are automatically deinterlaced -- whether I've checked "deinterlace" or not. Sometimes this problem goes away when I deselect Frame Blending, but more often not. Can anyone shed any light on this for me?
