Slow Motion Compressor

I started here and saw the ProApps post:

But, I'm just getting double identical frames? Is there something weird because I'm using 30p? HDV?
Source material is HDV 1080i-30p from a Sony V1U.
FCP is 5.1.4, Compressor is 2.3
From Compressor, my Frame Control settings are the following:
Retiming: High quality motion compensated
Resize Filter: Statistical Prediction
DeInterlace Filter: Motion Compensated
Adaptive detail: On
Antialias: 0
Detail Level: 0
Field Output: Progressive
Screen Capture of settings here: http://www.adventurefilmworks.com/slomo/settings.png
Original source file found here: http://www.adventurefilmworks.com/slomo/
I'm starting out just trying to get a 50% speed setting to work, so I selected Frame Rate of 59.94
Any Ideas?
Dual 2.0 PowerMac G5 Mac OS X (10.4.9) 3 GB RAM, Sony HVR-V1U, 1080i-30p HDV editing

Anyone have any ideas? Am I missing a setting somewhere?
Thanks

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.

Slow Motion choppy

I've tried to slow down a clip in FCP, and also did a trick with Compressor that's talked about in another discussion on here, and with both attempts, I'm ending up with choppy slow motion. What it's doing is holding on each frame for a period of time (depending on how much it's slowed down), instead of flowing smoothly between the frames and giving a nice slow-mo effect. Rather, it looks like a render job or something, frame by frame, da-da-da-da....and on.
Does anyone have any idea as to why it'd be acting like this? The sequence is set to 29.97 - the footage was captured from a DVcam, firewire, 29.97.
I got the tape from another person who filmed it - there's a chance that it was shot in 24p - could that be the problem? I took the tape and put it in my Sony Handycam to capture the footage. (I think the camera used to record was a Canon - a nicer, higher-end one, but not quite sure if it was 24p).
Thanks for any help.

I found out that the footage was shot at 24p with a Panasonic AG-DVX100. I was given the tape and captured it with my Sony HandyCam via firewire (hopefully that doesn't cause any problems - so far it looks good when playing back at normal speed).
As far as higher frame rate goes, I am used to doing slo-mo in FCP with footage that I shoot with my Sony cam - at 29.97, and it doesn't behave like this.
When I do the Compressor trick, it looks very similar to slowing it down in FCP, maybe just a little cleaner, but the timing and "pausing on frames" is the same.
If I understand you correctly, I don't believe it was "pre-processed" by de-interlacing, unless that would occur in the way I made the quicktime or something (but I doubt it - I did it as you explained).
Thanks for all the help.

Compressing .mov to mp4 comes out in Slow Motion!

I have Compressor version 3.5.3 but I don't think that's what the problem is. I'm trying to compress an 11GB Quicktime file down to a couple of GB.
It's a PAL .mov file, 1920x1080, 25fps, 48000kHz/16.
These are the Settings I chose :
Video: Encoder MPEG4, 1920x1080, 25fps,
Key Frame interval: I change 15 to 25. Is that wrong?
Bit rate: medium VBR
Audio: Mono because Stereo greyed out 48000kHz.
Bit rate 64kbps is what comes up with 48000kHz. (When I changed it to 16bit it brought 22000kHz)
Frame Controls Option is off. Is that correct?
The result was a clip in Slow Motion Video and Audio alike.
What did I do wrong? Is there an incompatibility somewhere? I'd be most grateful for any suggestion. Thank you,

Hello Russ, these are the 3 Inspector screenshots you requested:
1) Inspector for the Quicktime file to be compressed:
2) Inspector Summary 1
3) Inspector Summary 2
4) Inspector Encoder 1
5) Inspector Encoder 2
That's how I ended up with slow motion in the converted mp4 file. What do you make of it?
Many thanks in advance for any light you could throw on this.

Slow motion 50% export H.264 MOV (at half frame rate)

Hi,
I'm using a QuickTime MOV file (H.264, 1080p/59.94fps, 15 seconds) and have set slow motion to 50% (= 30 seconds).
Can anyone confirm that when I export this clip to 29.97fps I won't lose frames?
I have Compressor and think I found nearly all required settings except:
- Key frames - shall I use automatic or 24 or what? (How can I find out what the original key frame value was?)
- Frame reordering - shall I uncheck this option? (What does it mean? It's not in the manual.)
Many thanks!

If you want to make absolutely sure you won't lose frames, you should manually set a project to 29.97fps, import your 60/59.94fps and conform the video (Retime menu > Conform Speed [the retime menu is the 2nd one from the left over the effects browser area/under the inspector area]). FCPX will automatically frame for frame adjust the video to fit to the slower frame rate.
Key frames (video compression, not animation): a key frame is a complete image -- 100% pixels in use. Every frame between the key frames are only the parts of the image that change from the last frame (like Cel animation). Setting Automatic allows the software to make the best choices of when and where to create a complete frame. Otherwise, you can experiment with different values (up to All, which is pretty much no compression) to see what kinds of results you get and the overall quality (use very short pieces, like 5 -10 seconds.) High motion areas in video are always going to be the most challenging with respect to compression (particularly bitrate), so... it's worth figuring out what settings you like that will give the best results (and 5-10second clips don't take that long to render.) I generally use Automatic and adjust the bitrates to give the best overall results (which occasionally requires testing segments.)
Frame reordering: allows applications to "decompress" video frames in a different order than they are played, thereby allowing those apps that understand it a way to work faster. Larry Jordan suggests that this setting always be set for H.264 video (although I don't if I'm uploading to YouTube -- I try not to give YouTube any excuses for recompressing my video, so I try to have it already optimized before uploading... so far, it seems to be working.)

IMovie 11 quick time movie is in slow motion. why?

Sharing using Quick Time to make HD movie. Movie comes out in slow motion, but audio sounds okay. Followed online suggestions for settings. Settings are as follows: PLEASE HELP!

You don't say how the file was created for youtube. When you export a video from Flash you have a lot of options available to you. You can change the image area size, the frame rate, you can choose one of many video and audio compressors.
As a start, you should keep the image area and the frame rate the same for the video as it was in the original Flash file. When the Adobe Media Encoder opens, your file will show up in the Queue section with a compressor and a preset selected. You can select the format and change it to anything that you want. Since the default format has given you a poor result, select a different format or customize the existing one. There are many, many, options available. Take a look at the Media Encoder documentation for more information on those options.

How to get good slow motion w/FCPX?

Okay, so I've been trying to get some good slow motion video. I'm new to this whole video thing, but I'm fortunate enough to be able to have some cool toys even though I don't know how to use them yet! Anyway, here are my questions (prefaced by some details to help you answer my questions!).
What I'm working with:
Two cameras
1) GoPro shooting at 720p, 60 FPS
2) Canon Vixia HF G10 shooting at 1080i, 60 FPS
- In case my terminology is wrong, the GoPro shoots in 60p, and the Canon shoots at 60i....not sure the best way to describe it.
Editing with:
- FCPX
- I don't have Motion 5 or Compressor yet, but I can get it if its necessary for any reason
Goal that I'm working toward:
- I want to get some smooth "creamy" slow motion footage every now and then when the video I'm making calls for it.
- Here's a couple examples of the type of slow motion I'm hoping to end up with:
- (right about at the 3:10 point)
Problem I'm having:
- With the GoPro (60p), I can only slow down to 50% speed before it starts to look choppy. Slower than that Optical Flow will work a little bit, but it still looks very amateur.
- With the Canon (60i, but much higher quality video), I can barely slow it down at all without it looking choppy and sloppy.
Questions:
- Am I doing something wrong?
- Do I need to download other software?
- Anybody willings to give me a step by step instruction?!
- I'm stumped...any help will be great!
Thanks!

I'm a bit short having time for my tests, but what I found out so far.
• avoid any 'natural motion blurr' in your recordings
• if optional on your device, select super-short shutter speed (<1/1000th), depending on 'action' in front of cam (ever wondered why those demos are preferred in bright sunlight? )
• avoid too high 'angle speed' = too fast too close: if the picture content changes too fast btw. frame#1 and frame#2 the eye is not able to blend the content = stutter
• Optical Flow: excellent on small angle speed, failing on fast angle speed or rotation:
watch my short demo here (YT-link) testing speeds and blending modes:
(recording 720/60p, ~1/1000th shutter speed, Project setting 25p)
• notice the perfect blending of motion far away from cam (player girl in green)
• notice the unwanted 'warp' effects around the player in blue close to cam, esp. legs
• notice the 'wobble' of rotating ball in 10% slowmo ... that is beyond Optical Flows skills
What I've seen so far from the famous TWIXTOR plugin for FCPX/Motion5, it lacks the 'plus' features (e.g. seperating background/layers) and has to be handled as unconvenient as the old version for FC/e (copy/paste clips to lengthen etc). Info: the vers. of Twixtor for FC/e and FC/p differed dramatically!
=> imho, the actual vers. of Twixtor4FCPX isn't worth the 300$ (yepp, three HUNDRED) …
and my personal opinion upon marketing: a plugin shouldn't be more expensive than its host

Imported Video Plays in Slow Motion...why?

Hey Guys I hope you can help:
I set up a project with the following properties:
Sequence Preset: AJA IoHD 720p 23.98 Apple Pro Res 422 (HQ)
Capture Preset: AJA IoHD 720p 23.98 Apple Pro Res 422 (HQ) Varicam
Device Control Preset: AJA IoHD 720p 23.98 Sony VTR
Once this is set up I import a video clip with the following properties:
Vid Rate: 23.98 fps
Frame Size: 1280 x 720
Compressor: Apple ProRes 422 (HQ)
Data Rate: 11.2 MB/sec
Pixel Aspect: Square
After I import the file, I drag it to the preview window and play it....the sound plays normally, but the video itself is playing in slow motion....THIS IS DRIVING ME NUTS. Can any of you shed any light on this???
I drag the file to the timelime (get no messages from the system) and play it from the timeline with the same results.

Perhaps, tell us your system and your source footage is.
When you have it in the timeline, is there a fine line on the top of the timeline window? Red ,Green, or orange? Try and render it if you do.

Need suggestions for high speed, slow motion, sporting event to DVD

In a recent video shoot I've trimmed down a lot of video into several slow motion clips of 15%, 20% and 25%. They were shot at 1/500 on a GL-1 and "modified" speedwise in FCE without frame blending. In the past I've had problems with shadows in slow motion with frame blending on so it was turned off this time. As a full sized QT video everything looks just fine.
Being satisfied the video looked well I put it to DVDSP. When I worked it through in DVDSP (using all default settings)and printed the video I ended up with a horror show of bodies which moved back and forth and looking nothing like the full size QT quality clip. Bodies moved in one direction, the camera opposite them and at times the zoom working against both and it ended up looking like people moving backwards then forward and once in a while the shadows I'd hoped to get rid of.
I will assume that not blending did some of the damage, but it appears that the further the action is away (presumabley the camera movement is minimized compared to the movement of the players) it looks almost viewable, but on anything close the movement appears as if it is not always moving forward.
I will have to experiment, obviously, but I was hoping for a starting point. As an aside I exported the FCE scratch QT file to camera and reimported it to FCE as one large block, the same result on the DVD occured despite the tape looking excellent and the full sized QT file looking just fine also.
I guess the averaging of the compression comes into play, so what would be a way to tweak it to what I want instead of what's easiest for the program?
Thanks in advance for any idea!
Chuck

What format did you shoot? HDV? if so, you may be seein field-reversal artifacts.
Frame blending is kind of a misnomer as far as slomo in FCE and FCP go.
Are you using a pre-FCS version of DVDSP? why are you using FCE?
I've found one of the best ways to get slomotion is to up the frame rate using compressor with the frame controls turned on, then reconform back to your native frame rate with Cinema Tools. It's a bit of a workflow quagmire, but the results look good.

Slow motion blury

I'm using fcp4 and when I make a slow motion clip, it seems a bit blury. I'm slowing it down to about 65%. Can anyone help?

I agree. FCP blends frames so it always degrades quality. Also make sure you slow down in proper increments. Staying at %75,%50,%25 yields better results because it uses even frame blending. If you cant clear slowmotion you have to use Compressors Optical Flow Technology.(NOTE: I have compressor and i have a few things to say about it later) I don't have the details but I will post back when I do. There is an excellent thread here i saw on slow motion, once I find it I'll post it back. It tells you exactly how to use compressor slow down video. Compressor unlike FCP creates entirely new frames- it doesn't mix them. It really remarkable technology thats meant to convert from NTSC or PAL and vice versa but also has other applications- such as slowing down video. Now for compressor I have this to say-------------------------------------------------------------------I still don't understand why people are using compressor, it is horribly slow and doesn't show any significant improvement over quicktime pro encoding. You even said it yourself in step 2 where you showed that Imovie encoded your file in 30 min whereas compressor took 3.5 hours. I have a dual 2.5 and encoding using quicktime pro- which you can do out of FCP or Imovie or the actual program- is extremely fast- about double real time for CBR or realtime for 2passVBR. That means a 90min clip encoded in mpeg2 at 2pass VBR will take 90 min. This is normal. Compressor will give you anyting from 3 hours to 14 hours. Nonsense!! I always assumed something was wrong with compressor but now I see people are using compressor and its obsene encoding times thinking it is normal. It isn't. Please someone tell me I'm wrong or tell me why compressor is so slow. I just batch render from FCP or export from FCP- either case I always export using QuicktimePro!

Compressor 3 slower than Compressor 2?

Both myself and an editor I work with have found that Compressor 3 is 40% to 50% slower than Compressor 2.
As an example, I encoded a large (640x360) anamorphic H.264 from a DV film in Compressor 2, and it took a little less than 40 minutes. In Compressor 3, using the same DV film and the same preset, the encode took 56 minutes.
Both myself and the editor I mentioned before are using G5 based machines. Is that the issue?

Well, I have heard this lament before with the G5s, and all I can say is that I guess Apple is slowly starting to drop support for the PowerPC generation (it was inevitable). I assume you've upgraded to 3.0.1?
As for Motion 3 (and someone correct me here if I am wrong), I believe it's slower because of the full 3D integration. Whether or not you have a lot of 3D aspects, I think it still calculates for it, causing your response and render time to decrease.

Compressed .mov to mpeg4 comes out in Slow Motion!

Using Compressor to bring down an 11GB Quicktime file to a couple of GB. And it comes out in Slow motion!
The Quicktime A/V attributes are: Video encoded 1920x1080, PAL, 25fps, Pixel square, Field Dominance: Progressive, Audio: 48kHz/16bit
These are the Settings I used:
Video: Video enabled is selected
Allow job segmenting is selected. Should it ?
Frame Rate: 25fps
Key Frame interval: 15 . I tried 25 ?
Bit rate: medium VBR
Audio: Audio enabled is selected
Channels: I had to choose Mono, because with Stereo 48000kHz was greyed out
Sample rate: 48000kHz, quality High,
Bit Rate: 64kbps. If I change the bit rate to 16, the Sample rate becomes 22000!
Streaming: I deselected Streaming.
What did I do wrong? Is there an incompatibility somewhere between Quicktime and MPEG4? How can it be remedied? I would be most grateful for any suggestion. Happy New Year!

Hello Russ, these are the 3 Inspector screenshots you requested:
1) Inspector for the Quicktime file to be compressed:
2) Inspector Summary 1
3) Inspector Summary 2
4) Inspector Encoder 1
5) Inspector Encoder 2
That's how I ended up with slow motion in the converted mp4 file. What do you make of it?
Many thanks in advance for any light you could throw on this.

Imovie slow motion

i was wondering if there is a feature in the latest imovie that allows you to make some specific points in the movie "slow motion". thanks.

I, too, started searching for video effects in iMovie 8 to add slow motion. There is no way to do this in iM8. However, after reading other posts in this discussion I decided to go back to iM6. That's when the light bulb turned on...
I exported the video from my iM8 project, imported the same clip into iM6, added the slow motion then exported in DV quality to import in iM8. It worked!! Yes, I know it's a long way around but it got the job done.
I should mention that it is not obvious how to go about exporting an original DV video from iM8 so here are the steps I followed:
1) Select the video clips
2) Select Share->Export Using Quicktime
3) Click on "Options..."
4) Select Video Settings
5) Select Compression Type ->DV/DVCPRO NTSC (or PAL)
6) Set Compressor Quality to High
7) Click OK
8) Name and save your video clip then modify it in iM6
After you modify it in iM6 drag into the Event Library over the project you wish to add it to.
Good luck.

60i to 60p ... to 24p for slow motion purposes!

I hope I am not shot and killed for posting this topic as I (think) I am aware of the extensive amount of forums that already exist on this topic.
I shot some test footage at 60i on my Canon XH-A1. I would LOVE to see this slowed down to 40% speed running in a 24p timeline in Final Cut Pro.
I have FCS2. Surely this is possible. I am aware I need to convert my 60i footage to 60p footage but I am confused about whether or not Compressor can do this or not. Can I convert 1080-60i directly to 1080-60p? Or is this impossible? Does it have to be converted to 720-60p?
I would love to know how to make Compressor do this and if not, what can? Once I have this 60p footage (whether it be 1080 or 720), how do I put it into a 24p sequence in final cut? I almost got there using 720-60p but there was some wierd interlacing problem that was going on. Also, final cut did not use the existing frames to make it slow motion, it just spread out the 24 frames per second using normal frame blending.
Sorry if this is confusing, but I am confused! I don't want to use Optical flow or frame blending or anything, I just want to go form 60i to 24p at 40% speed using all the existing frames.
ANY help would be appreciated (or a link to somewhere where it can be explained effectively using FCS apps...)
THANKS!

I owe everyone an apology, because I gave the wrong information about the video file. As you will recall, I was frustrated that it appeared to play at only 23.97 frames per second in Final Cut Pro, even though I thought I had shot it at 60 fps. Yesterday I discovered why it appeared to play at a different frame rate, but the reason was so bizarre, so unbelievable, that I began to doubt my own sanity.
Friends, the video clip changes frame rate in the middle! Yes, it does. You see, I had been looking at a portion of the shot with the lower frame rate; later in the same shot, the frame rate increased to 60 fps. You may ask, how is this possible? I do not know. I only know that I shot it with the little Sanyo HD1000 camcorder, which records as AVCHD (h.264), and the clip changed to a slower frame rate when the shot got darker, then back to 60 fps when the shot got brighter. Apparently the camcorder reacted to the lack of light by decreasing the frame rate, in order to have time to gather more light for each frame.

Strange slow-motion typing slowdown

Hi folks, I am wondering if anyone else has noticed this issue I am having.
Every now and then randomly, and without any rhyme or reason in an application where I am typing in, it'll get slow for a second or two and the keystrokes appear in slow motion with a lag time slower than my typing and then return back to normal speed.. the beachball does not appear when that happens.
I have 4 GB of Ram. I can't remember if this happened or not with 10.5.1 or if it's a fault in the new firmware update for the keyboards.. so I though I'd send this out to see if anyone else has noticed this happening also.

Here's my workflow:
Export from FCP with your timeline with "current settings" and make either a self-contained movie or reference movie (your choice).
Then open the file in Quictime and chose export. Under your options category chose you preferred codec (such as Motion JPEG A) - set your frame size as NTSC 720x480 16:9 and commence downconversion. Your file should now be in SD format ready for mpeg2 encoding.
For what it's worth I think Compressor is a fairly easy way to go. Try exporting an HDV file out of FCP and then importing that into Compressor. Or just crack open Ouicktime Pro downconvert there and then use Compressor or DVDSP (which really is basically the same thing) to encode your m2v file.
