Shoot 720p 60 for Slow Motion on PAL DVD . . ?

Ever since I became interested in shooting slow motion, I've been quite envious of NTSC users because they enjoy 30 fps rather than PAL's juddering 25 fps.
Interesting to note that the +'grass is always greener'+ syndrome has kicked in though. A great many NTSC video makers are desperate to achieve the +'film look'+ while many over here, want smoother footage.
Personally, I fail to understand why anyone would want juddery footage, but then I detest the wavy camera phase that film makers are going through at the moment. Now I'm showing my age.
With the galloping technical advance of 'prosumer' camcorders, we now have a choice of formats and this has led me to wonder whether shooting in 720p 60 fps and then converting this to PAL DV could achieve a nicer slow motion than shooting 720p 50 fps.
I'm not in a position to run any trial just at the moment, but the idea's been in my head for a while now, and I wondered if anyone has any thoughts or experience on this.
Because of the nature of my subject, I cannot predict with much accuracy which scenes will be required at normal speed and which will be slow, so I shoot everything at 50 fps and then I can choose.
+PS. I'm not very technically minded so forgive me If I've overlooked some obvious flaw!+
I should add (although it's surely obvious) that I shoot in HD in an attempt to 'future proof' my footage. The vast majority of my audience has only recently converted to DVD, let alone HD.

Sorry, did kind of lack technical details but then there are precious few to consider, after all, overcranking (running a camera at a higher recording framerate than the intended playback framerate) has been the way this has been done for years, and the new video cameras that allow 60p recording make an ideal poor man's high speed camera, especially for 24p and 25p playback. Also its much easier just to tell folks what they want to hear

How to properly timewarp 59.94 footage for slow motion effect for 29.97 output

I have footage filmed in 59.94 that I want to use for slow motion effects and output to 29.97. Using timewarp I seem to get duplicate frames at times. What would the best workflow to accomplish the cleanest result? I've tried interpreting the footage at 29.97 and keeping it at its native 59.94. At this point I feel like I'm just confusing myself further by just trying random things. Thanks!

Always interpret footage as what it really is. If it is really 59.94 progressive then that's what it should be interpreted as. It will play at the right speed in any comp of any frame rate. IOW, if the footage is 10 seconds and you put it in a 99fps comp and play it back at full frame rate the clip will still be 10 seconds long. If you put it in a comp that's 15 frames per second, the clip will still be 10 seconds long.
Make sure you understand that.
There is a chance, and a good chance, that your footage is actually full frame 59.94 fps video. That's why I suggested putting it in a comp that's also 59.94 fps and checking for duplicate frames.
There is also a chance that your footage is actually 29.97 fps interlaced. If you separate fields and look at the footage in a 59.94 fps comp you won't see any duplicate frames.
To change the speed of the clip you just need to apply Time Remapping, Time Warp, or any of the other Time Time tools in AE. It doesn't make any difference what the frame rate of the composition is, you'll be changing the length of the clip.
To keep from creating duplicate frames you either need software that interprets the new, extra frames or you need to use an exact whole number multiple of the frame rate for rendering.
Where did you get the footage? What Camera? What are you trying to do with it? What is the final destination (delivery) for your project.

Using 720p 50fps video for Slow Motion

Hi there,
I've recently started using Photoshop Elements 9 for editing my action sports footage, and its a big improvement over free to use programs that I used before.
The thing that I have run into, and that I can't seem to solve, is making footage slow down.
I'm using both a GoPro camera (HD and HD2) and a Canon EOS 550D to shoot my video. Everything is shot at 720p @ 50fps so that I can use the footage slowed down when I want to use it that way without making it choppy (in normal 25fps export video (can be 720p, but I might use 1080p as well))
I've set up a project in PE9 using the preset for PAL-DSLR-720-50fps so that (me thinking) I can import 50fps footage without losing frames for importing. However, when I use the time timestretch function (through right click menu) and set the strech to 50% (so effectively 25fps) the video doesn't appear to have the extra frames. Even after rendering, if I foreward 1 frame at the time, every second frame is simply just a copy of the previous one. I've checked the file properties through PE9 and it says that the file is 50.000fps, so there should be 50fps available to build the footage from (yet only showing 25fps in frame by frame mode).
In searching the forum I've found some other suggestions to solve this, including the 'Interpret Footage' function. I've tried setting it to 'Interpret as 25fps' to see if this changed anything (as to smear out all available 50 frames over a 25fps clip, doubling its length), but that also retured with a copied frame every second frame.
I've also tried setting the project preset to DSLR-1080p @ 25fps to see if that might have an effect, but as soon as I import my 720p video it changes the project preset to AVCHD-LITE-720p50. Using that returns the same issue (btw, what is the difference between DSLR setting and AVCHD?). Using the AVCHD-720p @ 25pfs together with 'interpret footage at 25fps' also reverted to 50fps as soon as I imported the video file.
Frame blending isn't an option as it doesn't actually blend them. It just overlays the two frames and changes the opacity of the upper one (or so it seems), creating this weird blurry overlay effect, instead of interpolating the objects between the two frames (but maybe I'm asking for too much on this function).
Can someone please help me solve this slo-motion effect issue? I really want to use the full available 50fps footage I have shot to create smooth slow-motion in a 25fps export video (i'm not looking at reducing it much more than that). It seems that half the frames are dropped out as soon as I import into PE9.
Thanks,

As we've often discussed on this forum, Go-Pro footage rarely behaves in this program as source footage. The best solution we've found is a conversion to an editable format.

In fact, mixing video footage of any types is usually not a good idea. Especially when your project settings may not fully match either.
Try using just the footage from your Canon. When you add it to your timeline, do you see red lines above the clips? If so, you are not using the correct project settings for your footage.

Tried to shoot 60 FPS for slow motion, but ...

I have a DVCPro HD clip, 720P, 59.94 frames per second. I was hoping to get a medium slow-motion effect in FCP. So I imported it and put it in a 23.97 frames per second sequence. It shows at regular speed. Hmmm...
I looked at the clip in the Viewer. I found a part of the action that lasts one second, and I counted 60 frames for that second. But in the Sequence, that same action shows only 24 frames.
Then I got a brilliant idea! I used Modify - Speed to slow it down to 40%. I hoped I would see all 60 frames of that one-second bit of action. But instead of showing all 60 frames, FCP uses only about 24 frames, and copies each frame once or twice to stretch out the action. So the action looks jumpy instead of smooth.
A friend last last month shot something with the Panasonic HVX200 at DVCProHD 59.54 FPS, and he got a smooth slow motion effect in FCP. But he moved out and isn't answering his phone.
Any suggestions would be greatly appreciated!

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.

HVX footage shot at 720p50 for slow motion...how do i???

Hi
I'm shooting some test slo-mo footage on my HVX (PAL).
I've shot as 720p and a frame rate of 50 and when I import it into FCP the footage shows 50 frames per second now how do I get that into a 25 frames per second time line and thus in slow motion?
Hope someone can help!

Ok figured this out. Use cinema tools and conform footage to 25fps.

Question about Camera/Premiere Settings for Slow Motion Video

I'm new to shooting video with cameras that have manual options, so I'm not exactly sure how I should set up the camera settings. It's a Canon 60D. Basically in the video I want to make, I'd like to have a lot of normal speed to slow motion transitions. Some of the video footage will be very fast paced, so I'd like to slow it down as much as possible without making the video appear jumpy. I assume I should change the frame rate on the camera to 60 fps. Is there anything else I should adjust within the settings?
I will be editing with premiere elements if you know of any additional tips for that.
Thank you in advance!

The speed of your camcorder doesn't matter. You can apply Time Stretch to any video clip.
There's a limit to how much you can slow it, of course. With that camera and Premiere Elements, you're not going to be able to slow down a water spray so you an see the individual droplets or anything like that. But, if you combine TimeStretch and Frame Blend, you should get very good results slowing your footage down a certain amount.
How much you can slow it and still be satisfied with the results is kind of a judgment call. So I encourage you to experiment and see what your tolerance is.

FCP 7. Best technique for slow motion

What is the best techique or plugin for effective slow motion?
Right-clicking on a clip and adjusting time is not good. I have tried sending to Motion and adjusting the timing there but it softens the image.
Is Twixtor the way to go??
Thanks

I'm late to the party but somehow I ended up here. I'm reteaching myself this now. I remember Captain Mench had a solution for this on the ProVideoCoalition site at one point for taking 60i footage and conforming to 24p using Shake. The key element was Optical Flow, Motion uses OF as you know. But I've just been doing a bunch of tests all night with some 60p (59.94) that we shot last week. The CrumplePop tut is the one I've been following for Motion 4 and some random youtube stuff using Time Warp for AE tests. The consensus seems to be each technique, including Twixtor, has limitations depending on the footage. AE better in one instance, Motion/Shake/Boris Red in another, Twixtor generally better than everything but still with flaws. Let alone the other factors like did you shoot 60p to begin with? Was the shutter 1/60 or 1/1600? Other great tidbits like this slomo conversion chart and this other Motion tut, 3 steps and bang! I gotta go to sleep, hope this helps.
Forgot this guy, of course he has some great tips from his friend on using Twixtor.

60fps Footage rendered to 30fps for slow motion

I know that to render footage shot at 60fps down to 30fps so it's slow motion you can use Cinema Tools in Final Cut Pro. I've done so with a buddy's system. I, though, have FCE HD and am wondering if there is a solution for me that doesn't require dragging footage over to my friends studio. Since FCE doesn't include Cinema Tools, is there another piece of software I might use?

aha! I now see what you are talking about. If your camera shoots for instance 720p60 - as does not GH2. So yes - MovieEdit does a good job of this - if you are willing to use the extra disk space for another copy of the movie file.
If you don't want to use extra disk space, save a reference movie of your file (will be a tiny file) and use this method on it:
http://mingletron.com/?p=222
an easier link to get Atom Inspector is here:
http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wo/5.1.17.2.1.3.3.1.0 .1.1.0.3.12.3.3.1
just change all the timescales of the ref movie that are not audio (ones that are not 48000 or 44100) to half their current value in all the mvhd and mdhd, then save and drag the ref movie into FCE. Sound will not work - it will be at the original speed and just end halfway through, but that's easy enough to fix - just unlink the sound, slow it down to 50%, chop off the excess and re-link.
To make a ref movie you need quicktime pro, or the free qtsync should also do it.

Camera Choice for Slow Motion

I have a choice of two cameras to do the type of work I want to do. This work would involve slowing down a fly fishing rod and adding graphics. (or golf club)
The two cameras are the Cannon XHA1 and the Sony HUR-VIU
I intend to shoot at 30p and use Adobe to slow the image down. I have been told to be careful about which camera I should use, but I am unclear as to the reasons one camera would be more suitable than the other is.
Could someone help me?

Between the Canon and Sony, I would go with the Canon.
Panasonic's HVX200a would be the superior choice, but is about $1,000 to $1,500 more. Plus, your options are MiniDV tape for DV25 or P2 card for all the myriad HD options plus MiniDV. But...there's no tape option for HD (like HDV does) so that may affect your purchasing decision if you're going the HD route. It comes with a 16 GB P2 card, but you may need more than one card if you're shooting a lot of footage and won't have time to offload the files to a computer.
The next option you may want to consider is the Panny HPX170. Similar in many ways to the HVX200a, but the main difference is no tape drive, only P2 slots.
Then there's the HMC150, which shoots AVCHD onto the little SD (or SDHC) cards. There's also no tape drive here, but the SD cards are relatively cheap and from what I'm reading so far, the quality of the HD is comparable to the HVX200a when shooting 720p at the highest quality setting (PH I believe...?). That camera is available for about $3,500, so that should definitely fit your budget, and give you a little extra cash to buy more SD cards.

Video shot specifically for Slow Motion playback

I thought I might try starting a thread for sharing video shot specifically for the purpose of playing it back in slow motion. For the first example, I shot this flag flying on a perfectly clear day. We have had a lot of really clear blue days lately much to my delight.
My Panasonic DMC-GH3 can shoot 1920X1080 at 60 (59.94) frames per second. That is frames, not fields. So interpreted at 29.97 frames per second it plays half speed. This was taken a step farther and played back at 24p. So if my math is correct, it is playing at 40% (close enough).
Funny, but the camera actually has a setting to shoot video to play back at 40% but it seems redundant to me. Perhaps if the video was never going to be edited, just played back, that could come in handy.
I used a recording from the US Army Band because I was in the Army and I am just used to hearing it played by the Army Band. I thought of adding the lyrics since I really like them. All four verses. I just didn't have enough footage to do it right and I love the sunshine and blue skies. So here is a link to the four verses for those who want to play the video four times and sing along. Nobody? Are you sure? I did it. Couldn't help it.
I am probably going to put up a couple more copies. One with the Pledge of Allegiance and one with the first verse of the National Anthem. In the meantime, I am enjoying all that blue sky.
If your camera can shoot at a higher frame rate to play back at 24p, please post some examples. If you are particularly good at using Premiere Pro to modify the playback speed of video, let's see what you've got.
The camera was siting on a GorillaPod shooting at approximately a 30 degree angle. The lens was my 100-300 set for 183mm, the equivalent of 355mm on a 35mm camera.
ISO 200. This video has not been modified in any way other than interpreting it to play at 24 frames per second, to trim off the beginning and the end (to eliminate the shaky setup and take down of the shot), and I also added cross-dissolve transitions at the beginning and the end. No color correction of any kind and no stabilization. This is what the camera saw.
I really love the flag of the United States. If you live in the United States I hope you do too. Today is Washington's Birthday. So Happy Birthday to the Father of our country. Our first President. This is my present to our founding fathers on this day, and I chuckle to think about how shocked they might be at the number of stars on the flag, and I am sad when I think how mad they would be if they knew how far we have strayed from the principles they fought and died for.
(I'll bet old Ben Franklin would love the Internet though.)

Steve, regarding my request getting inside flag and changing shutter speed etc..
I have to admit right off that I don't understand this myself as I should...and I don't have a motion pic camera OR the DSLR ....which I can get in April ...at which time I will be off to the races trying to figure out how to use it.
But the gist of what I was getting at ( though hazy and not understood by me ) I'll try to explain...
Motion pic film cameras with the mechanical gizmo that pulls down the film ( frame by frame ) have a rotating shutter ( the gizmo is typically called a mitchel movement I think ). The rotating shutter has a mirro on the back side which allows a person to 'see' via some magic stuff ( prism ? ) what is in the frame ( eyepiece ). I guess it's similar to a SLR mirror but this one spins.
This is what it looks like
So, a normal setting for that shutter is 180 degrees... and it spins so that each frame gets 'exposed' by the open part of the shutter. Then when the shutter is spun to the closed side ( no light getting to film frame ) the 'next frame of film' is dragged down into place to be exposed. So that happens typically 24 times per second. It is pretty fast.
Some motion pic cameras can shoot even FASTER ( amazingly )...and you can therefore increase the FPS. Then as you know when it's played back at 24 FPS in projector, it looks like slower motion.
Unfortunately if the FPS is increased the 180 degree shutter may not be letting in enough light to get a good exposure anymore... so that shutter can be adjusted ( called the shutter angle ).
So a 45 degree shutter would let a lot more light hit the film ...cause it lets more light through its rotation time. This is the part where I can totally confused....and hopefully I'll learn more when I get the DSLR how this is handled with modern digital camera.
Cause, if you let more light hit the film by adjusting film motion pic shutter it stands to reason there will more " blur " from the longer exposure. However, this is offset by the faster FPS speed... so this is why I am curious about it...
As a point of fact motion pic cameras can be synchd to CRT screens using a mechanism that times the shutter to coincide with the horizontal 'lines' of the CRT ( timing of frames of interlaced signal )... and the shutter has many 'angles' it can be adjusted to ..
So, anyway, I guess this is something to explore when I get that DSLR...
I was thinking it might look cool to have slo mo with more 'blur' to make something look a little ghost like...kinda like my flag picture with time exposure...
crazy idea...

Best workflow for slow motion from Canon 7D?

Hey guys,
I am working with a slow motion clip for the first time and I am realizing that there isn't really an easy workflow with this. First of all, the clip was filmed with the Canon 7D, 60 fps. When I put in on the timeline, obviously I get rid of the audio. But then if I slow it down to 50% I get the typical frame blending crappy looking image that FCP gives me EVEN THOUGH the sequence settings are set to playing 30fps. In reality, I thought that when I import the clip in the timeline with those settings the clip would automatically be double-length... Stupid me. It's treating the clip like a normal regular clip and so when I slow it down it does the same thing it does with all clips - a terrible job at slow motion. So basically, at 50% it should be playing every frame and there should be no frame blending but apparently that's not the case.
So.. What's the best way to work with this? I tried putting the clip on a separate sequence and then slowing it down which did a much better job but then I had to export the clip out of FCP and bring it back in as a "new slow motion" clip if I wanted to preserve the effect. What happens if I have more than one clip? Is there a way to do "batch export" on all of them at once and not just one clip at a time? What's the fastest and best way to work with a 60fps clip in FCP and mix it in with the rest of my clips which are 30fps without it looking like crap?
I also just found out about Optical Flow in Motion and that's great but wow... the render time is many many hours for a 5 minute clip... that's crazy. I don't have that kind of time.
So... Please help! Thanks guys!

Step 1: Convert to ProRes. Log and Transfer, MPEG STREAMCLIP, Magic Bullet Grinder...whatever. Make it ProRes.
Step 2: Duplicate the clip if you want to also have it normal speed, because Step 3 is not undoable.
Step 3: Take into Cinema Tools and CONFORM to the frame rate you want. 29.97, 23.98...whatever the rest of the project is. This conform is permanent. It takes seconds, but is undoable. Thus what you did in Step 2.

Workflow for dual NTSC and PAL DVD project

Hello,
I am really in need of professional advice here, and any tips would be GREATLY appreciated. I am not an expert in Final Cut Studio, but I am OK to get things done on the project I am working on. Some things, despite cracking through multiple manuals, I can't properly figure out... THANKS AGAIN for any help!
I am working on a DVD project which I want to release in two versions: NTSC version in US, and PAL version for Poland — same content. Content was created using DV-NTSC Quicktime files, made on import from an American mini-DV SONY camcorder into Final Cut Pro. All the titles created in Photoshop were created in 720 x 540 and converted to 720 x 480 for the sequences.
I made one NTSC DVD using Studio Pro, and it seems to work okay, with some minor tweaks. But I really need to know what is the best way to make a PAL DVD with minimal quality loss. I need to set up this project correctly, because I have a **** of a lot of work to do, and I don't want to screw it up by incorrect setup.
So many questions... Should I use separate Final Cut sequence files, with different settings, for each disc? Should I finish my work in sequences with NTSC settings in Final Cut, and then use Compressor to export to PAL from within Final Cut? Really, what is the best workflow for something like this? I would dearly appreciate any advice.
Many thanks!
Rad

First off - you can do this. Finish your work in NTSC. Then go buy the Graeme Natress plug for FCP. http://www.nattress.com/standardsConversion.htm
Download and install the app. THen follow the instructions on his site. It's a short turorial movie and you're done.
Heads up - you'll need to first export NTSC Quicktime files of each of your movies.
Hope this helps.

New Sequence Question - for slow motion video

Hi,
I'm a very new user of Premier. I've recently had issues with choppy playback of my preview videos. After much research I believe the issue was down to two things. Firstly my sequence did not match my input clip, I had it set to my desired output. Secondly, I was editing video across my network, rather than bringing it locally to my PC. I've fixed the latter issue by copying video files to my local machine and then moving them back onto the network once I've finished editing.
The advice out there essentially seems to be to match your sequence to your primary input video. I've done that and it helps. However, it's raised a big question for me. My input video is from a GoPro and is at 1080p 50fps. I ultimately want my output video to be slowed down to 25fps (resulting in a constant slow motion effect throughout the entire sequence).
If my sequence settings are set to match the input clip (50fps) and I slow the video down by 50%, will that result in an unsmooth video? My basic understanding is that if I slow 50fps video down by 50% then Premier will have to double the amount of frames. Where as previously, if I slowed it down by 50% Premier had enough frames to play with as the output video was 25fps.
Hopefully my question makes sense! Any advice on what the best approach is? Or is this a complete non-issue when it comes to exporting the video (providing I export to a 25fps formart)?
Thanks,

I think you said it OK, you are just missing the right words to do what you want. Let's walk through this for you, and for others that might read it later.
If you take a 50 frame per second video and put it into a sequence created from it, then slow it down 50% it doubles up each frame to achieve slow motion. Not what you want.
If you take a 50 frame per second video and put it into a 25 fps sequence, it drops half the frames to play at normal speed. Not what you want.
What you want to do is interpret the 50 fps video to 25 fps, then drop it into a 25 fps sequence. Each frame will play at 25 fps and generally be smooth as silk.
I don't have any 50 fps clips handy, but here are examples of taking 60 fps to 30 fps. (Excuse the idiot way that we Americans do things. Our 30 is actually 29.97 etc)
First, right click on the clip in the Project Panel, select Modify, and Interpret Footage. Then change the 50 to 25 - similar to this image:

Can the iPhone 4 shoot video in slow motion?

Can the iphone 4 shoot in slow mo? This video says they shot it in slow motion but I don't think it can?
http://www.youtube.com/watch?v=_rV0tzYx8Gk

This question is too funny...
Nothing can shoot in slow motion (since things always occur in real time). You can only *play back* a video in slow motion (i.e., reduced frame rate).....

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.
