Bad slow motion

I shoot in 720p 50. When applying slow motion, say 25% or 10% the result is far from good. I have tried to use normal, frame blending and optical flow. And the optical flow gives the worst result. It is difficult to describe the result in other word than extreme blurriness and bizarre movemets. Is this something that FXPX can not handle or I am doing something wrong ?

Rotoscoping is the art of making i.e. a Bird flying accross the sky, stand alone... What I mean is that it will in this case leave you with two layers of movies (Or two movies)
Imagine duplicating the clip I am describing above, twice... One is lying in the main timeline and its duplicate is lying directly above it. Both clips identical.
Now, we'll "mask out" the background of the above clip. So that if we solo the that clip you would see all black(Depending on your movie background (The black is actually transparency) and then the bird flying accross the screen. In the clip below we'd "Mask out" the bird and replace its place in the film with content from it surroundings (Much like clone stamping in photoshop) ... In the end and if the clip above (with the bird only) had a carefully created mask, we'll have the bird on one layer and the background on the other.....
(IF it was a steady shot thus not panning, craning or sliding) we could create a clean-plate of the background and just have that sitting as a still image while the bird is flying)
Anyway, now we can apply optical flow to the bird and if the mask is tight, the most motion blur will have vanished and our result is great looking... Now there might be a few places with optical flow artifacts... But then we'd just mask those out as well ;-)
This level of masking (Rotoscoping) cannot be done in FCPx -- you would use After Effects for such or motion... However, AE is much greater for such (in my opinion at least ;-)))
In above case, I would problably wind up with MUCH more than 2 layers of video. More like 50... The clip I wrote about in my earlier post had about 500 ;-))))
Rotoscoping is vast and great... And it is more of an art than a technique. Basic rotoscoping would be to apply a mask to a man's sweater and keyframe it to fit the motion... Then alter its hue or tag a big sign saying "Rotoscope Me" on his chest..
Possibilities are endless ;-)))
Mocha Pro which is a planer tracker is the best tool on the planet to help one automate the "Masking & Tracking" & it comes free in special version with After Effects.
hope this helps ;-)

Slow motion looking bad

I have tried to slow a video clip down to 30% speed. It looks smooth when played back in FCE, but when exported to a QT movie, it becomes jerky with brief stuttering of frames.
I have tried the techniques described in other posts but nothing seems to work. First, I tried it with just frame blending. Then I superimposed a copy of the clip, and used the de-interlace/flicker filters without frame blending.
The original footage was shot on Super-8 film, transferred to DVD, and converted to DV.
Any suggestions as to how to make the slowed clip play smooth after exporting would be greatly appreciated.

Have you tried the Toltzman solution ? It works only for 50% slow down, but it seems to work better than the standard Speed command. Let me quote it from an old post:
"When you slow down a clip in FCP/FCE, the application does not use the 60 (or 50 in PAL) fields/second of interlaced video, which can help to achieve very smooth 50% speed video.
Here is a recipe for converting your 60/50 fields per second in to 60/50 frames per second for a nice, smooth slow motion effect at 50% speed.
Slow motion in FCE using both fields of Interlace video to get smoother slow motion at 50% (uses all 60 fields).
1) layer two copies of video in timeline over the top of each other.
2) apply a de-interlace (1) and blink (2) filter to the top copy and set the de-interlace to use the Upper field. Set the Blink filter to an on duration of 1 and an off duration of 1.
3) apply a de-interlace filter to the bottom copy and set it to Lower field.
4) Set the speed of each layer to 50% and turn OFF the frame blending.
The top layer and bottom layer should now be interleaved. The top layer will contain only the upper field (repeated across 2 frames) and the bottom layer will have the lower field (repeated across 2 frames). The Blink filter will switch back and forth between the layers to use all fields as frames.
If your field dominance is different than NTSC DV, then you'll have to reverse the de-interlace settings on each video layer
By Douglas Toltzman"
The result is that each single field (both upper and lower) is repeated twice, while with the standard Speed command only the upper field of each frame is repeated 4 times, and lower fields are discarded.

Slow Motion Looks Bad

Hi,
I have FCE 4, and in my movie, i have slow motion. However, when I create a master sequnce, the slow motion looks jerky because my video is sd and the master sequnce is HD, but the sequence needs to be HD because I have pictures, and the pictures look better in HD. Does anybody have a fix for this? PLEASE HELP!!!!!!!

There isn't much you can do if the video has to be in the same sequence as the still images. Remember though when you go to DVD it's going to all be back to SD. Your HD might look better in FCE and might produce a better result when compressed in iDVD, but I don't know if it's worth the damage you're doing scaling up the SD video a huge amount.

Why do my slow motion clips look so bad in iDVD6?

I'm not sure if this is an iMOVIE or iDVD issue but when I burn DVDs the slow motion sections look really jittery; much worse than they were in my movies that were made from the programs I installed in 2004. Any suggestions?

Hi Chris:
Pretty much an iMovie problem..read this discussion and pay special attention to anything Matti Haveri says..

FCPX choppy slow motion, picture quality and effects

is it just me or does final cut pro x have really bad quality picture. two main things i have noticed in using this software is the slow motion is really choppy even after rendering out with optical flow and there is a lot of vibration in the picture. lines are jumpy and when adding effects it gets much worse, also there are black lines at top and bottom of screen.
i was using edius prior to getting a mac and it was as smooth as butter, slow mo and all. im kinda bummed about the whole final cut thing. please help.
thanks.
i dont think it has anything to do with my mac. im running a new imac 3.4ghz i7 quadcore 16gb ram and 2gb grafix card.

yes, those are the properties i use.
so there is somthing wrong with the picture?
not just me?
is there anyway to import it at 60i?
for some reason it doesnt give me that option..

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.
MacBook Pro 17" Core 2 Duo 2.33 GHz Mac OS X (10.4.8) 200 GB HD

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!

H.264 export from AVCHD source results in slow-motion video; any ideas?

Hello, I'm trying to export a 1080i project with AVCHD footage using the H.264 Bluray profile. The resulting video looks good, but runs in slow motion. The starting footage is AVCHD 1440x1080 (1.333). When I export using the MPEG2 Bluray profile, everything runs fine. Thank you for any suggestions.

Thanks for your reply. My source footage consists of MTS files from an AVCHD camcorder. The files are 1080i anamorphic, so 1440x1080, with an aspect ration of 1.333 and a framerate of 29.97fps. I used one of the AVCHD sequence templates in Premiere CS5 that matched the video files.
I'm exorting using the H.264 Bluray preset for 1080i. I tried several of the profiles (1080p, etc), but they all end with the same bad result. The video plays, but seems to be playing at half speed. My 15-minute clip takes 30 minutes to play, even though the timline in VLC or WMP reports at 15 minutes. The audio sounds fine, but stops after 15 minutes (as it should). It's obviously out of sync, since the video is playing at half speed.
I have read a few other articles indicating it might be an issue with the way Premiere is interpreting the interlaced footage from the MTS files? This is beyond my area of knowledge.
When I encode using the MPEG-2 Bluray profile, it works fine. The video playback speed is normal.
My end goal is to edit my MTS files from the camcorder, encode using the H.264 profile, and place in an MKV container for playback on my XBMC-based HTPC. I'm also considering exporting as a high-bitrate MPEG-2, then using another encoder (HandBrake, etc.) to create the x264 MKV. Any other recommendations would be greatly appreciated. Thank you.

60p Slow Motion still jittery and stroby. What am I doing wrong?

I shot in JVCs 60p. When I try slow mo in either an HDV or SD 30 fps time line, it looks just as bad as 30p slow motion. Could it be that once I put the clip in the HDV 30p timeline, FCP treats it just like a 30p clip? I've tried altering the motion blur and speed, but that makes no difference. FYI, in order to use my JVC "SDHD60 p" clips - which FCP doesn't recognize- I had to convert the QT files using the HDV-DV program. But QT files look fine and smooth at regular speed, so I don't really think that's the problem.

Okay, upon further experimentation - I found that once I've created the slo mo in the 60P timeline, I can export the sequence using QT compression to a 72030p clip and import into the timeline. But this is a big pain. It seems it also works to edit everything in a 60p timeline. The 30p material must render, but it doesn't take long. Anyone out there experimented with this??

Wave in slow motion video type

Hi.When i use slow motion video type, it is some waves in the picture and i think its because of a problem.but when i use video type there is not any wave.
what is the problem and what should i do?

Music puts video in slow motion

I love the fact that I can get online here and seek help. IT has always helped me before-so hopefully I will get lucky now. I am using Imovie 9-- am new user and so far have learned how to use it-compared to the later versions-- a few learning curves but not bad.
My problem is when I import a sound effect or music clip- the video portion goes into slow motion. Quite simply- when I remove the sound effect-it resumes to regular speed? what am I doing wrong or how to I just add the music and have the video play as is?
THanks so much!

There is no output when I start smplayer from the console. In vlc there is no problem. In smplayer the video playback slows down when I maximize the window using maximize button of the window itself. When I resize the window to its maximum manually or use the full screen button of smplayer, then there is no problem. It appears to be a problem with smplayer, because in mplayer there is no problem when I maximize with the window using the maximize button.
I tried nvidia-304xx yesterday, but that didn't help.

Twixtor slow motion problem

Hello, I was using twixtor to modify some footage I have and make it slow motion but for some reasons everytime I turn the speed down the footage is blurred and it has some kind bad frame timing. I modified the frames from the composition to be exactly like the ones from my footage so there shouldn't be any problem.

I took a look at the footage and it looks like the frame rate is wrong. It's hard to tell because you put up an FLV file and didn't post the original footage. The FLV does not contain all of the frames and the frame rate doesn't match the movie because there are a bunch of repeated frames.
Here are a few thoughts.
You shot with a DSLR so there are some rolling shutter problems that must be fixed to keep the car from distorting. There are plug-ins for that. Fix the rolling shutter problems (jello cam) first.
You may have interlacing issues and 3:2 pulldown issues. Make sure that every frame of the movie is properly interpreted. You can do this by dragging the original clip into the new comp icon, then doubling the frame rate of the composition, then interpreting the footage as interlaced. If the footage is interlaced you'll see a different frame every time you advance one frame. If you see 2 or 3 different frames, then 2 duplicate frames, the footage has 3:2 pulldown. You must remove it. If, after you set footage interpretation to separate fields you only see pairs of frames, then the footage is truly progressive.
Once you have the footage properly interpreted make sure that the interpretation is exactly copied to the appropriate fields in Twixtor and experiment with all the settings, isolate the background, and you should get acceptable results.
None of these suggestions will work if your footage is misinterpreted. If you want to post the original footage to You Send It or Dropbox I'll gladly take a look when I can.

Export slow motion from my 5s.

Hi there. I would know how to export slow-motion videos from my phone 5s to my computer without losing any quality.

I wouldn't change applications against a deadline.
Slow motion is not an easy effect to do in post unless you shot more frames per second than you needed for standard speed. Making 30 frames a second into 60 frames requires each frame to be printed twice. What were your expectations or what have your tried before?
Especially with HDV, which starts out so heavily compressed, by the time it gets slomo'd and transcoded back to MPEG2 again, yeah, I imagine it's gonna look pretty bad. You can obtain some expensive software to do the optical flow pixel interpretation without buying FCS2 but that's up to your client's needs for smooth slow motion. Rendering optical flow, we've heard, takes for freakin' ever, even on the best machines.
Some HDV users will chime in over the next few hours or days with more helpful advice.

Slow motion clip doesn't publish slow on Facebook

My video on my 5s publishes fine, just not slow motion. Is there something I'm doing wrong???

Hi,
this Effect you describe is exactly my Problem!!
I am trying to export a clip to flv containing lots of slow motion,
but it has a bad quality compared to PRO 2.0 -
the resolution, bitrate etc. are the same - what am i doing wrong?

Fear: Oddly base sound when putting on slow motion. (single play

Hmmm, i get this ugly base sound, when im turning on slow motion, and also when i/it turns off. The game runs great, exept for this.
Is someone else getting this? (I know how it should sound, cause i had good song before the new .07Patch, but this was bad.)
And if someone else gets this, i wanna know if creative got a soloving of this :smileyvery-happy: hehe
And if someone wants to know, i got an..
Amd athlon 64 3400+ (old socket, 754)
Epox EP-8NPA sli
ATi Radeon X-800XT (256mb)
PC3200 536mb
Creative X-Fi Extreme Music
(Windows XP Pro. x64)

I finally found a workable but temporary fix. This keeps the distortions away until you restart the game, even if you quickload or start a new level. I'm not sure why or even how it works, but it works. I've been playing FEAR:EP for about 4-5 hours now, distortion free. In fact I just beat the expansion pack (I played about 5 levels) with no problems. It's kinda tricky how to do it, I'll try to explain it as best as I can.
Load a level. Got distortions? Go into the sound options and turn off all the hardware sound options (hardware, EAX, advanced HD). Go back into the game and play around some (endure the distorions, please), until the distortions seem to magically go away (getting into some combat and jumping or using a lot of slow-mo helps). We're not done yet! Now that the distortions seem to have gone away, immediately go back into the options and turn all the hardware sound options back on. Don't quickload, change levels, restart the game or continue the game without turning hardware sounds back on. The distortions WILL return. Now, the distortions should be gone until you restart the game. You may have to try it a few times if the distortions don't go away in software sounds. But if you can make the distortions go away in software, then immediately turn on hardware, they go away altogether for this session.
Good luck!

Weird Slow motion effect with Motion4 and FCP7.

Hi everyone,
I was testing a simple slow motion clip when I encountered a weird issue with it.
Basically the clip of a person running in a room where there is a bookshelf and the weird effect is that it looks like there is an "halo" around the person and within such "overlap" everything on that path looks "melted/vibrant" distorted.
To better clarify the issue I uploaded a sample clip here:
http://www.vimeo.com/5891093
After doing some tests I've found a workaround to this. So the sample clip shows the problem and the portion without any problem.
The clip was shot in XDCAM EX 720p 25fps.
After ingesting and importing the MOV file into Motion I had exported the slowed clip out of Motion using the same codec XDCAM EX 720p VBR.
When I imported that MOV into FCP I got that weird effect on both canvas and final export to H.264.
As second test, instead of using the export from Motion, I decided to use the Motion project in the FCP timeline. Once rendered (as the motn clip was in the Motion Codec Decompression) as XDCAM the same issue appeared on both the canvas and final export to H.264.
At this point the strange thing was that if I opened the Motion project in the viewer it was working perfectly fine.
I then decided to export within FCP the Motion project to XDCAM 720p before instantiating it in the timeline.
So did that and I got a 720p clip that I imported in the timeline without any rendering needs.
With that clip the canvas was playing ok and so was the final export to H.264.
As the initial work in Motion 4 was ok and I didn't see any issue, I thought this might be some sort of FCP 7 issue (or some bad settings that I have on my system).
Anyway I've found my work around and just decided to share here just in case someone else could understand the behind the scene of this.
During these tests I have tried to place the Motion project on different timelines (in ProRes 422, ProRes 444) just to see whether the issue was due to a combination of factors including the XDCAM codec, but didn't fix the problem.
Cheers,
Armando.

Just for the record, I made another test with a different material and now I start thinking it could be a Motion4 weird behavior than an FCP7 issue.
I have shot another clip this time with an in camera slow motion (shot @60fps in XDCAM EX 720p 25pfs format), then applied to Motion4 for another 50% optical flow time remapping.
This time after checking well at Motion results, I can see the issue in the bookshelf area with vibrant/melting spots.
After importing the Motion project into FCP and then exported as self contained MOV in XDCAM EX 720p, the issue is gone as in the other tests.
I went back to the previous tests I made and checked better in Motion; the problem was slightly noticeable even there in one test.
So I guess it is Motion producing that weird output and not FCP, which seems btw fixing the issue.
Regards,
Armando.
