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.

  • Best frame rate for shooting motion in 60 interlaced?

    Hello,
    I'm working with some footage that includes some boats moving quickly. A lot of that was shot close up. I'm amazed at the artifacts that interlaced is producing. Quite frankly you feel you need new glasses when you look at it. Freeze a frame and the horizontal edges of each phase jump out. I have no idea what the shutter speed is in these shots but just wonder if this effect is totally unavoidable shooting interlaced. Possibly my camera was shooting at a very low shutter speed, so that might exagerate these artifacts, but even if I had shot at a very high speed they'd still be there, just perhaps to a lesser degree. Right? So any thoughts on this? Any ideas about the best way to capture motion when shooting interlaced. (This is ten-year old footage, so I suspect I'll have to try and recreate the event shooting progressive this time.)
    Thanks.

    The newer Flat Panel TVs and DVD players do a great job at de-interlacing.
    Digital broadcast @ 1080 is still interlaced. So modern TVs need to be able to handle that.
    If you're making standard def DVDs out of 1080 HDV footage you may want to consider de-interlacing when you down convert to 480. And down convert to Pro Rez rather than hdv. You'll have fewer artifacts that way.
    You can also learn how to author Blu-ray which will be a better product for your hdv footage.

  • 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.

  • Standard frame rate for 1080p NTSC?

    Hello and thanks for having me! Very new(b) to Adobe Premier, so I'll throw something basic out, thanks for your advice:
    the short version:
    What is the 'standard' framerate for NTSC 1080p? Does this framerate differ from what you would use for output at 720p,
    and would you choose different framerates depending on delivery method (web vs. bluray)?
    the long version:
    I have at my disposal a very capable rig to work on, and just doing some basic editing for my audio CV reel. The source material is usually 1080p and sometimes 720p, whether it be streamed into my capture card HDMI from playback sources, or full production originals which I have scored for clients.
    Therefore, while editing my reel together, I'd like to work at full 1080p and downconvert for smaller formats afterword.
    However, I am very new to video editing, and not sure what framerate to work in. I see the available selections of NTSC 1080p at several framerates,
    and I am aware of all available framerates in the US and abroad, so my question is:
    What is the standard frame rate for NTSC 1080p used for BluRay or highbandwidth web transmission? Some are telling me 'use 60, its standard'. Others tell me its 24. Still others say 24 is only for working with film, or interpolating other sources to 'make your stuff look like film'.
    Thank you for any answers or resources, and have a nice evening!

    For Blu-ray you can have two frame rates at 1080 resolution, 30 fps interlaced, or 24 fps progressive.  1080p/30 will not go onto a Blu-ray.
    At 720 resolution, you can have 60 fps or 24 fps, both progressive.
    If you want to work at 1080p, your only option is 24 fps.
    Web delivery is a different matter.  There are no defined standards and pretty much anything you like will play on the web.
    (On a side note, drop and non-drop frame refers strictly to the timecode information, and does not regulate frame rates.)

  • 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.

  • 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

  • Separate sampling rate for two different channels for a USB-6009 daq

    Hi, 
    I am using a USB-6009 and incorporating the 'daq assistant' to change the sample rate.  I am trying to find a way to set the sampling rate to two unique values for two separate channels.  I've tried setting up two daq assistants and adjusting the sample rate different for each channel, though this does not work.  Is there any way to set the sample rate high for all channels then reduce the rate for a different channel - or an alternative?  I would appreciate any input on this, thank you!
    - Anthony
    Solved!
    Go to Solution.

    All tasks on a DAQ board that use a sampling clock must use the same clock.  Therefore, you cannot have two tasks on the same DAQ board sample at different rates.
    Alternatives would be:
    1. to combine all of the channels into a single task and just accept the extra data
    2. get an extra DAQ board to use in parallel
    There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • Frame rate for FLVs in FLEX, 10, 12, or 15?

    We are using Flex to create a rich internet application that
    delivers a lot of video which is then synchronized with a series of
    screen events. Our concern has to do with the frame rate for the
    FLVs. We are shooting at 30fps and have been told that the delivery
    should be a multiple of 30, hence either 10 or 15fps. But Flex is
    at 24fps, so we were wondering if the FLV should be delivered at
    12fps. Any advice?

    you need to optimize your code/display especially if you're creating an app for a mobile device.
    one of the easiest things to do is to enable the cacheAsBitmap property of most movieclips and assign a cacheAsBitmapMatrix to those movieclips that would benefit.

  • 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 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.

  • 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.

  • Best bitrate/frame rate for 1080 and 720 HD?

    What seems to be the best bit rate and frame rate to use for
    HD video for best playback on a Mac Mini. Plan on using H.264 encoder
    to be compatible with iTunes,etc. (I like iTunes for consolidating all my media).
    I have downloaded several movies from iTunes, both HD and SD, and they all
    look great and playback smoothly.
    I will be using a 32" Samsung HDTV.

    FWIW, I've been working on a 720p project and have found the "proxy" on the cinema display pretty good for judging focus. We thought we found some material with soft focus and actually took it to a post house to look at the tape on a CRT. It was out of focus.
    If I remember correctly, I think Decklink made an adapter that would allow you to view HD material on the cinemadisplay. Maybe someone else can pipe up with the specifics. Someone else also recently posted this link: http://www.matrox.com/video/products/mxo/home.cfm.

  • How to sync NTSC and PAL clips to same frame rate for multicam edit

    Hi there,
    First time poster so sorry for the newbie question. I'm trying to get 2 standard NTSC clips and 1 standard PAL clip about a hour long each which shot the same event at the same time, to sync up so that I can go to multi-cam and edit them like a movie sequence. I tried that, but they start unsyncing about 10 minutes in. I gather it's because of the different frame rates. I tried using "interpret footage" and changed the PAL 25fps to 29.97fps and everything got sped up. I tried rendering the PAL clip as an NTSC clip but it ended up looking a bit fuzzier. As I want to end up with an NTSC clip in the end, how can I make these clips sync up properly?
    Any, tips to help this newbie greatly appreciated with many thanks.

    Hi Jonathan,
    It's not always so easy to do NTSC <-> PAL conversions, and it's impossible to do them in Premiere while maintaining any degree of quality.
    You can do a good job of this with AviSynth (freeware) but the learning curve may be a bit steep for a newbie. I also hear that ProCoder ($500+) does a good job of this but I've never tried it.
    As for the sync, you can chop up your PAL clip within the muticam sequence (leaving some "holes") and match up particular points manually. You'll obviously have to edit around the holes.

  • Best Data Rate for Export to DVD as Quicktime Movie

    Hello - hope someone out there can help me!!!
    I put together a slideshow for my high school reunion using iMovie HD 5.0.2 and need help with settings exporting it as a Quicktime movie.
    *I want to export it to a DVD* so that I can play it on a friend's laptop and I'm not sure if iDVD would be the way to go - my friend has a Macbook Pro I can borrow so it might be okay - I am worried about the fact that I've been working on older software. (I have read about opening iDVD and bringing in iMovie project vs. "share to iDVD"). So they suggested instead of iDVD I just export as a quicktime. Then I can burn it in Toast (v.6.0.2)
    Wondering about *BEST DATA RATE?*
    In export settings I have:
    compressor set at H.264
    frame rate: current (should that be DV-NTSC?)
    key frames: automatic (?)
    encoding: best quality/multi-pass
    should data rate be automatic?
    Some details that might be relevant to helping me:
    *Stills brought in as clips with cross-dissolves, only two uses of "Ken Burns effect"
    *Some stills were in the project from my LAST reunion - I realize I should have reimported all the stills since I am now recompressing them, but it's too late now!
    *no audio
    *Slideshow is about 45 mins long, file size says 5.52GB although when I looked into exporting it last night it said 9+GB - not sure why
    *Using a G4 Tower (not my ancient laptop) with OS 10.4.11, Dual 533MHz PowerPC, 1.5GB SDRAM
    iDVD version is 6.0.4
    please help if you can!! thank you in advance...

    Are you trying to burn a standard DVD or are you trying to put a QuickTime .mov file on DVD media?
    A standard DVD doesn't worry about file size (only the duration).
    A "data" DVD is limited to the type of media used. A single layer DVD is about 3.7 GB's.
    In order to make a data DVD you need to keep the data rate low enough to not exceed the DVD media playback abilities. They can't handle the higher rates found in many of the preset options.
    You can avoid all of these headaches by telling the viewer to "copy" the .mov file from the DVD to their Desktop. Then nearly any of the presets option will work.
    H.264 is a great video codec and the "automatic" preset should work just fine. Use "multi-pass" for best quality (takes a very long time). Remove the check mark for "Audio" since your file has none. Leave it checked and you waste file size because a silent audio track would be added.
