Fast frame rate on playback

I am putting together a slideshow with video clips in Photoshop CS6. When I play back my work, instead of showing it to me at 30fps (which I have it set to) it's playing it at 7.65 fps. Very fast. How do I change that?

Hi Benjamin and csuebele, thanks so much for your replies. I think perhaps that the video function in Photoshop isn't robust enough to manage what I'm attempting. I've got (literally) hundreds of photos that I'm fading in and out of a fixed background. At a couple of points, in what would eventually be a video with a soundtrack, I have video clips that come in. While my picture clip indicates that it's, for example, 15 seconds long, when I hit the play button, it whips through it in a couple of seconds and the (30.00 fps) in white at the bottom of the timeline workspace changes to (7.65 fps) in red. I attempted to render a video last night of half the project to see if it would play correctly when rendered, but when I got up this morning, it hadn't made any more progress in the render than when I gave up and went to bed last night. It was a good experiment to use photoshop but I'm afraid (agh!!) I'm going to have to go to iMovie to make this work. :-( Thanks for trying to help, though. Linda.

Frame Rate Export-Playback Issue

Hello,
I'm relatively new to FCP 7.
But here's the problem..I have a timeline with the following sequence settings:
720p
H.264
50fps
But somehow whenever I export it in .MOV it seems to have a playback issue. All my audio gets jumbled up..it isn't synced anymore.
Doesn't seem to have a issue when I export in .3gp or in .m4v
Can someone help?
Thank you.

Yup...that's a problem. FCP and H.264 don't mix. Sync issues, export issues...don't edit H.264 native in FCP, period. If you use FCP 7 or earlier, you MUST convert your footage to an editing codec, like ProRes. And use ProRes sequence settings.
A quick fix you can try is to go into the sequence settings, change the COMPRESSOR to ProRes 422...and render the sequence, then export.

Checking playback frame rate

Hi Guys,
The answer to this question maybe painfully obvious, but I have just installed the Ati X1900 for G5 and want to check how well it's doing I'm going to use the test files as in this discussion:
http://discussions.apple.com/thread.jspa?messageID=4626023&#4626023
My question is, where do you check the playback frame rate in Motion, again sorry of this is obvious I just can't seem to see it.
Your help would be very much appreciated,
James

Hi,
if you get the preferences up, and go to the Appearance pane, there is a check box to show the frame rate during playback. Thhis will then apear in the bar below the toolbar icons when you play back.
thanks

Video frame rate change from video to video

HI all ,
when I use labview 2013 I found some strange in acquiring avi video
when I acquire video from my computer the fps change from video to another one
some video fps reach 800 fps and other reach 180 fps what is the problem

A lower frame rate is actually expected behavior if you are playing video through LabVIEW. This KB explains that LabVIEW analyzes the video one frame at a time and keeps it in the system memory on the CPU. This can result in slower frame rates during playback. If you would like to simply view video through your front panel, it may be a good idea to embed Windows Media Player in the VI through an ActiveX control.

Final cut pro slow frame rate

So whenever I import P2 files into an event I seen to have a slower frame rate during playback. the footage is good because it plays normally in the import media window but it will at a slower frame rate once imported. the video format is 720p 24 frames.

Where do you keep your projects and events? What are your system specs?

HDV MPEG2 Video Playback in QuickTime - frame rate too fast!!

Hello All,
I'm having a very strange problem which just began this past week when I upgraded to QT 7.2 (darn me, I'm a video pro, I should have known better than to do this mid-project!). I am editing a film with HDV content: 1280 x 720 pixels, MPEG2 video (.m2v file type).
I have the MPEG2 plugin for QT.
When I open the file in QT Player, it plays the video almost 2.5 times faster than the audio, increasing the frame rate to do so. For example, if I view the Movie Properties for one particular file, and compare the sound track to the video track, it will claim that that the sound track has a duration of 7:03:24, whereas the video duration has a duration of 2:49:27. When watching the video, it plays it back too fast. When I import the file into Final Cut, the same "sped up" file is viewed.
I think this is a QuickTime specific problem because I downloaded VLC Media Player (which can also open MPEG2 files) and it opened and played the same MPEG2 file perfectly and at the correct speed.
I tried uninstalling and downgrading to QT 7.1.6 (and then re-installed OS 10.4.10) - but the problem still exists. So there must be something else that was installed in this QT update that I haven't been able to figure out that is causing this very weird problem.
I'm at a standstill with my FCP project because all the files it refers to in my sequences use the same QT engine - so all my video files are playing back too fast. Yikes!
Please can anyone help me or provide any insight, I'm happy to try anything or post more info.
Thank you,
Catherine
P.S. I'm going to post a similar thread over with the FCP folks to see if they have heard of any similar problems.

Sorry to dig up an old post, but I am having the same problem. Does anybody know a solution, it seems to occur on all MP2 movies, HD or not.

What is the suggested frame rate to record in for fast / slow motion processing from a clip recorded

I want to create a video however I only have 1 dslr camera and I want the ability to post process the clips I record to be either in slow motion or fast motion. I don't want to have to record something in 24fps then 60fps. is there an ideal frame rate for both. What are some of the best practices for this in regards to recording and post processing in Premiere Pro.
Example of fast and slow video. Thanks.
http://vimeo.com/75259949

The ideal is to shoot in different frame rates, one for real time footage and one for fast or slow motion clips. This is called under and overcranking. It means you have to decide when shooting whether the clip will be real time or not.
Less than ideal is to shoot everything at one frame rate and then slow it down or speed it up later. It's less than ideal because the effect is never as perfect as the ideal method. Especially in PP, which does not do very well with slow motion to the point I recommend using After Effects instead. (At least with 24 fps media.)
On a side note, you can help solve the horrible slow-motion problem:

Playback drops frame rate when context menu opens

Hello,
I was wondering why is frame rate of the video drops when I open the context menu, the playback seems to go down as much as 5fps, and it goes back to normal when the context menu is closed.
Thanks in advance.

lghtanddrk, if you send me a link to your AVCHD MTS file, I can trying exporting it as a MOV file and see if I get the same issue. For me QT seems to be slowing no matter what HD file I give it.
What camera did you use to shoot your footage and how big is the AVCHD file? What's the data rate of your MP4/H.264 file? Again, if it's possible to get some of your MP4 footage, I can check if I have problems playing it.
I have two partions on my machine: one is WinXP SP2 without the updates and QT7.3.1 (for Avid XPress Pro) and the other has WinXP SP3 with all the updates and QT7.6.4 (I think that's the latest one). So, I can try on both to see if there are issues.
When you export as DV AVI, are you exporting as a SD (720x480?). I know that HD is square pixels and SD is non-square. The HD is 16x9 and the SD is 4:3. You could try and export your AVI as 720x540 square pixels or 720x480 non-square i.e. NTSC (CCIR 601) or try exporting as 854x480 square pixels to give your original 16x9 widescreen at SD resolution. I haven't looked at this stuff for a while, so, I'm kind of guessing here!

Importing video Frame Rate Off???

I am importing video which was shot on a DVX 100 at 24p the image plays fine on my playback deck but when I Play the digitized footage in FC it appears to be in fast forward... Not sure if this is a Frame Rate Issue???

I don't understand. Did the captured clips playback fine in fcp last night? How did you digitize them? You need to either use the correct capture preset in fcp or modify an existing preset. If you're using another piece of software to capture, you gotta let us know this info.

Subtle Frame Rate Variation Effects

I am working on a project to create a silent film look. In particular I am after capturing issues associated with the frame rate variability associated with both cameras and projection at that time.
Some thoughts based on my reading...
Seems like two issues are at play. One is that the capture may have been at around 16 to 23 frames. It seems that unless people were going for comic effect they were not intentionally sped up by showing at a faster projection rate. In looking at some old classics by and large people seemed to try to match capture and projection.
However there is a “crispness” associated with the quality of the movement. My guess, I am totally new to this, is this results from 16 to 29 fps capture - less frames in a second to provide the perception of smooth movement.
My thinking is that I should see if I can convert my base footage to a sub 20 fps frame rate that covers the “crisp” movement aspect.
In looking at old films it seems like there is another dynamic at play. There seems to be the equivelent of wow and flutter in analog play back devices (phonographs, cassettes) in relation to the timing - it changes in a subtle way over time. Perhaps there is a way to introduce subtle timing “white noise” to simulate this effect.
I am just coming back to FCP and Motion after a several year layoff, so I am not completely familiar with ther current capabilities.
So with that my questions:
1) I dreamed up the above with respect to approach. Any merit to this? Other ideas?
2) Are their tools in fcp studio to do a quality frame conversion to sub 20 fps?
3) shooting. Initially I thought that I would want to shoot at 24p in order to get closer to sub 20 fps. Maybe it makes sense to shoot at 30p or 60p (my other two choices) to create more frames to get to a higher sub 20 result. Thoughts?
3) Thoughts / approach to getting wow and flutter to simulate variable projection and or crank camera capture?
Thanks in advance for any help.

As Mark said, the Bad Film filter does a lot of weave and frame jutter automatically.
Another thing to try in addition to Bad Film are the retiming behaviors in Motion, particularly the Stutter and Flash Frame behaviors, which can introduce the kind of timing errors you are talking about into playback of your video. You can also apply a Randomize parameter behavior to the Retime Value parameter to get more interesting random playback effects.

Frame Rate Error playing back h.264 encoded files in QT

I originally posted this in the FCP HD forum, but was told that I might be able to get help here.
I really like the h.264 codec, but I have to use Quicktime Conversion, instead of QT Movie, when I export in FCP. I get a 'Codec Error' when I try to export as a QT Movie. That is the first problem, but I work around it.
The frame rate issue comes up when I try to export at larger screen sizes like 640x480. I have no problems at 320x240, but when I move up to the larger screen sizes the resultant QT mp4 plays back at 1/2 the specified frame rate, no matter what frame rate I try. It is really bizarre.
I tried lowering the key frame number to reduce the processor load on playback, but this had no effect. This was a tip I picked up here.
I tried lowering the bit rate, too. The only thing that 'fixes' it is to go back to the lower screen size.
The problem is reproducible when the file is played on other (faster) computers.
Any ideas?
thx
mike

Open an H.264 video codec file on two machines (one of which is more powerful than your current one) and compare the data viewed in the Movie Info (Command-i) window.
QuickTime, by design, drops frames to insure playback. You'll see the same issue when viewing any HD movie trailers. I get poor frames rates from anything above 480.
Newer HD (1080i) videos may play at less than one tenth of the designated frame rate on older machines even though they use data rates that should (technically) supported.
Blame it on advances in computers. I remember 90X60 "videos" at 8 frames a second that would "stall" during playback. Now we all want HD movies.

Frame rate fluctuations

I know sounds weird... I have a simple movie that is set at
48fps that when run from a staging server runs noticeably faster
than when running locally. Note, same client and browser, the only
apparent difference is where it is being served from.
Is there way to control playback frame rate outside of the
SWF file, like in Javascript?
thanks,
jr

Thanks for the reply... I don't mean to be disrespectful but
the issue is not the 48fps (although that is a frame rate I have
never used before).... It does it at 30, 24, 12... I probably
should have mentioned that as well.
I believe the key symptom is that the same client/browser was
running the movie at different rates depending on where the movie
was being served from. This led me to think that somehow the
movie's frame rate was being controlled externally such as through
a Javascript call. However, in my limited experience I have not
seen any evidence of being able to do this.
Is there or should I just attribute this to a ghost in the
machine?
thanks,
jr

Frame rate for camera does not match with AVI output

Hello,
I'm taking a video from a Basler A504K camera of well plate bottoms deflecting down. I have a frame rate indicator from the Vision Acquisition to see at what fps the camera is acquiring images, and I also have a frame rate controller at the IMAQ AVI Create VI.
The problem is when I set the frame rate at the Create VI. The higher I set the frame rate, the fewer frames it seems to take. For example when I play the videos on Windows Media Player, at 10fps, the video length is 60s. At 100fps, the video length is 6s. At 20fps, it's 30s, and at 50fps, it's 12s. Obviously, the video length decreasing by the factor by which I increase the fps. But since higher frames per second videos show a slower/longer videos, since they have more images to display per second?
I need to be able to see a slow increase and decrease in the well deflections smoothly. At high frame rates, the video goes by so fast that I cannot analyze the deflections. At low frame rates, the video is slower, but there are too many missing frames so the deflection is not smooth (ie. you see no deflection one second, and the next, you see the peak deflection without seeing the gradual increase in deflections). It is very hard to find an "ideal" frame rate, so I was wondering if there was another way to control the frame rate such that I have high fps, and longer video lengths?
I'm attaching my VI. The bottom loop is where all the Video and Camera controls are. The top loops is to control pressure gauge and valve (just ignore that loop)

Hi B.J. Kim,
The problem you're seeing with the fps and video length makes sense to me. If you keep the overall frame count constant and change only the rate of playback, then the video time will be indirectly proportional, as you have noticed. Just from simple math, it appears like you kept the video image at a constant of 600 total frames while changing the frame rate between 10, 20, 30fps, etc. If you're looking to have more resolution in you video, maybe you could increase the actual frame rate of acqusition from your camera. You may also try placing a small millisecond wait in your while loop to slow down execution speed.

Slow Motion and Frame Rates?

Hi I have a Sony NEX-VG20EH camera and it has an adjustable frame rate. I have put the frame rate on 8000 and recorded some footage. When i load it into Premiere it is still showing as 50.00 fps. I want to do some slow motion stuff but when i slow it down to 10% it is still quite "jumpy". Any ideas?

While many cameras DO offer the ability to "overcrank" for a short duration, such as to capture a golf swing in slow-motion, I looked at the specs for your camera and don't see that feature listed.
Raising the shutter speed means that the shutter is open for a shorter duration during the exposure of each frame of video. At slow shutter speeds, fast motion will look blurred on a freeze frame or during slow playback, because the subject moved quite a bit during the time the shutter was open. A fast shutter will "freeze" each moment in time clearly, but also lowers light sensitivity, so best used outdoors in good light.
It can be fun to play with shutter speeds - on my honeymoon, I was shooting the airplane prop out my window and cranked up the shutter speed until the prop STOPPED and I could read the serial number off of it in my viewfinder!! Note this was in the old days with CCD sensors - the new CMOS sensors have skew which warps the image in many cases.
Note that very high shutter speeds will result in choppy motion, so only use as needed.
