Is the best frame rate 31fps?

In years past, 31fps was considered the best frame rate, as far as getting the best performance on both Mac and Windows. Has that changed with hardware acceleration? Does the frame rate still mater in getting consistent performance?

I'd say anything beyond 36 - max 40 fps is too much and unneeded. Plus, a higher framerate would be too demanding on CPU resources as flash player needs to redraw the screen as much times as the framerate count. This is the main reason for flash player causing a slow down in system response. Take for instance moviemaking - it has a framerate of 25 fps and this is enough for even the most dynamic scenes. A framerate between 24 and 30 for flash is considered to be smooth enough and at the same time not too much demanding on system resources

What is the best frame rate to shoot/edit with for export to DVD?

Hello, I am going to shoot some instructional martial arts videos that need to be exported to DVD. I haven't exported to DVD since 2005. I am curious what the best frame rate is to shoot with and edit in Premiere to export to DVD. I've read conflicting information online. Some forums say that you can edit in whatever frame rate you want as long as the output is SD, 30i, which seems outdated to me.
I'm shooting on the GH2, so my options are 1080 24p (which has terrible strobiness compared to other cameras at 24p), 1080 60i, 720 60p, and apparently there is an HBR firmware update that allows 1080 30p. I want the motion to be as unstroby as possible, without being too soft. My friend's camera can shoot 1080 60p and I'm considering buying the G6, which also shoots 1080 60p. But I've read online that 60p to DVD looks choppy.
Any advice would be greatly appreciated. Thank you very much.
Jeremy

Thank you Jim. I do have one more question with regards to your advice:
I am putting the new firmware on my GH2 today, so I will be able to capture 1080/30p as opposed to only 1080/60i to edit in the 30p timeline. Is there a reason you would prefer 60i over true 30p at the same res? I've had problems with interlacing in the past never quite going away and getting funky when doing slow motion and other effects.

What is the best frame rate to use for movies watched only on computer scre

Hello all,
I'm UK based, and so use the PAL system of 25 fps. This works well enough if I want to make a DVD, but I'm now starting to work on projects that will only ever be seen on You Tube or Mobile Me - that sort of environment.
A portion of my work features stills, and I prefer to use Photo to Movie for pan, scan, and zoom and rotate - it's much more versatile than Ken Burns in iMovie.
However, I can't seem to get perfectly smooth pans when viewing on a screen. Depending on whether I use 25 fps or 30 fps, the pan is slightly 'trembly'. I've tried all the codecs, different frame rates etc, but I can't seem to remove this problem. A pan created in iMovie is perfectly smooth. Does anyone know why I can't replicate this in Photo to Movie?
I'm starting to suspect it isn't really a frame rate issue, but something else - but there my knowledge runs out.
Can anyone offer advice on this?
Thanks in advance.

For Video projects, use the same frame rate as your source material. If your camcorder shoots PAL use PAL. For photos it should not matter.
I get a whole lot more control over Ken Burns in iMovie. I always thought that iPhoto was just kind of random with no control.
I guess I'll have to go back and look at it. In iMovie 09 and before, iMovie did not handle vertically oriented photos very well for Ken Burns. This is fixed in iMovie 11.

How do I convert 1080 24p NTSC to PAL format, - whats the right frame rate ?

I have some footage* that I want to convert to PAL HD.   Currently its in NTSC HD.
What is the best frame rate / frame size to convert into? Do I have to convert it up to 50fps (or 25fps) and turn it into interlaced?

PAL is 720 x 576 pixels interlaced (bottom first).
If it's 16:9 aspect ratio, you need to select "Anamorphic" and the frame rate it 25 fps.
If you need help with Compressor settings - I use Best for everything including re-sizing - processing is slow but the result is excellent.
I believe you can use MPEG Streamclip for converting, but I have not tried it.

Best frame rates for 4 different cameras in multicam

Well, I've been flopping around in different threads on this forum, but I think the question is beginning to finally take shape for me. Basically it's all about deciding on frame rates for four different cameras I will be using to shoot a 6-day intensive course I will be teaching. The video will be primarily for computer viewing (YouTube, Quicktime movies). Here are the cameras:
2 new Canon cameras capable of frame rates of 60i, 30 frames per second progressive "recorded as 60i", and 24 frames per second progressive also "recorded as 60i" (there is a known issue with importing the 30 frames per second into fcpx, as fcpx does not recognize this as progressive, but ClipWrap can get around this).
1 Sony capable of 60i, 60P, and 24P
1 Sanyo capable of 60i and 30P
Possible settings:
Just do all at 60i, but people say this is not so good for computer viewing
Canon at 30 fps (using ClipWrap to see it gets recognized as progressive), and the Sony and Sanyo at 60i. Will this cause syncing or other problems, mixing frame rates like this? How bad a hit in quality is 60i on computer screens?
Canon and Sanyo at 30 fps, Sony at 60i
Same as #3, but use JES Deinterlacer to get Sony 60i to 30 fps.(I tried this out, by the way, and the resulting frame rate, after deinterlacing, showed up in the inspector window at 30, not 29.97. Is that a problem?
Anyway, I aplogogize for wearing out my welcome on this forum, and I thank everyone for creating such a wonderful bank of information.

Not sure what you're trying to achieve here - for the best overall quality, if possible, choose a frame rate that all the cameras can achieve. That way you won't lose quality in the conversion.
If you're not satisfied with that, you need to do some tests to see which gives you the effect you like best. Nobody here can help you really - it's up to you.

What is the max frame rate in depthFrame

In v1.8, I remembered the frame rate can be up to 30fps in depthFrme. what is the max frame rate in depthFrame in the v2.0? And how can i set it? thx!

Depth (and IR, body, face and HDface) frame rates are 30fps.
Color is 30fps unless low light mode is detected then it automatically switches to 15fps.
If you're using the multistream source it will stream at the lowest framerate from the chosen framesources.
When you're using separate sources they all stream at their own fps rate.
Frame rates can not be set by the user.

The best Bit rate for a 1 hour film

Hi all
Just a quick question does anyone know the best bit rate to use to compress a 1 hour film. I want the best quality possible
Any advice would be gratfully recieved
Thanks

If you're using Compressor and it's a one hour encode then use the CBR setting with a bit rate of 6 or 6.5. Also encode your audio to the industry standard .ac3 file format. The combination of audio and video bitrate is always a compromise between quality and having consumer DVD players stalling or choking because the combined birate is too high.
However, the media content you're encoding will always determine how you should encode: video with lots of fast action needs the VBR setting, whereas the CBR setting can be used when there is little action. But generally, the CBR setting in Compressor will do an okay job with project durations of one hour or less, regardless of the action in your video.
Hope this helps.

How to set the Codec, Frame rate, Bit rate, and Resolution for iMovie 10.0.5

To upload a video to Vimeo, I need to be able to set the codec, frame rate, bit rate and resolution to make sure the file is compressed to under 500 MB. Where in iMovie 10.0.5 am I given the option to adjust these settings?
Thank you!

Another question is in continuous mode, NI DAQmx uses Samples per channel to determine the buffer size. But according to the website you specified, it says if the acquisition is continuous (sample mode on the DAQmx Timing.vi is set to Continuous Samples), NI-DAQmx will allocate a buffer according to the following table. And for sample rate between 100 - 10,000 S/s, the buffer size is 10 kS. So if I set the sample rate to be 5000 S/s, and set the Samples per channel to be 20000, then what exactly the buffer size is? 20 kS or 10 kS?
Thanks.

What is the best scrubbing rate for youtube?

what is the best scrubbing rate for youtube?

Ummm... can you elaborate? why do you think a 1-pass would be better? Before i go through another 5 - 6 hours of compression, I would like to understand a little bit better... 2 0r 3 word answers aren't going to help me at all. Sorry.
Lisa <
You have about three thousand pages of manuals, why do you think we can shrink that information down? Compression is really difficult to understand and to control. There are dozens of Web sites you can explore or you could look at amazon.com and buy yourself some training systems. If you are going to be doing a lot of compression and encoding, you will learn it the same way everyone else does, slowly. It's often easier and faster and therefore cheaper to pay a service to do your encoding. Spend a few hours reading the Compressor forum.
Consider that you don't need to waste mjuch time rendering entire projects. Just assemble a short collection of problem scenes and use different settings till you get something you like. To confuse things even further, encoding results are totally subjective and a terrible compromise. You give up image quality to save time encoding or to gain program length. Youinvest tons of set up and encoding time to gain control the image quality. And you must process the audio separately to get the best use of your delivery media's capacity.

Best frame rate , resolution and shutter speed Canon XF 305 for chromakeying

Hi,
I have to shoot some footage with the Canon XF305 (green screen Chromakeying) And the only progressive frame rates I can choose are ( 25P 1920x1080) or (50Pand 25P 1280x720).
What shutter speed do I have to use?
What will be the best quality choice for keying?! The output will be Vimeo at the end. I have a Xenon 6core 3.2, Memory 24 GIG, GTX580.
Of course I know the best resolution, but I mean the best choices for keying.
It's done in PAL.
Thanks David

A high suhutter speed is improtant for crisp edges, especially if your codec is not frame-based, because your subjects will have little or no motion blur. 125th seocnd at least. faster if you can get it. Requires lots of light. You must not trade off depth of field because focus is critical to good keys, too, and you must not add gain because noise will degrade your key.

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:

How to change the maximum frame rate of the camera by changing the image size?

I have two acA2040-180km cameras which are connected to 2 NI PCIe-1433 framegrabbers, I am monitoring my cameras by LabView, maximum allowable frame rate is about 187 for full resolution images, but I just need a small fraction of the images, I know if I make the images smaller, FPS will get higher, but it isn't possible by changing the image size in NI MAX, I've also tried to change the size by defining the region of interest in the grab setup.vi, but it would be after going to camera so it isn't the case as well, so I need a VI to go to the camera before starting to take photo and define the region of interest which is going to be captured, would you please help me to find it?
Please help me, this problem get me stuck!!!

Have you tried changing the image size using property nodes as Bruce suggested? Do remember with Basler cameras, reducing the width only will not affect the transfer speed but the reducing the height will. Have a look at the frame calculator to understand what you frame rates you can acheive with certain settings:

FCP interprting the wrong frame rate

Hi
My client has delivered some footage using the DVCpro codac (not HD)
Quicktime reads the file correctly as 25fps but when I import the file into FCP, FCP shows it at 32fcp. Although the duration is correct it just shows black when it runs out of frames until it reaches the end.(too short)
I have tried to export a DV version using Qicktime but again FCP still reads it as 32 fps
Any thoughts would be appreciated.

QT and FCP, it seems, get their meta data info from different places. What I would do, and try this from both Quicktime Player and FCP, is export the clip and save it out at the same codec but specify that the frame rate should be 25. This may help clean the clip up without destroying the original.

Is the best frame rate 31fps?
