After adjusting frame rate audio is too slow

I was having trouble with my video being too slow (Nikon d5300 recording at 1920x1080 and 60i frame rate) and I changed it from 59.94 to 29.97 and it corrected my video but now my audio is too slow. What can I change now to fix audio so that the video stays corrected?

I hope this is what you guys were talking about.

  • Core Audio : Disk too slow (prepare)

    Can anyone help me. I have created a track that will not bounce
    because it always comes up with this error message: Core Audio: disk
    too slow (prepare). I cannot bounce tracks individually for the same
    reason. I have tried deleting some tracks that i dont need but it still does
    the same. I have 700 and something ram. Is this not enough. I have
    logic pro 7.1 and am using a few ultrabeats in the song. Know Any
    tricks i can get around this problem easily with. Any help would be
    greatly apreciateddd. thanx in advance.

    The drives in the rear positions are on an ATA-100 Bus, those in the front are on an ATA-66 bus. The CD is on an ATA-33 bus, and no Hard drives should be sharing the CD cable. ATA-66 and ATA-100 are plenty fast enough not to be a bottleneck, as long as you are not experiencing low-level correctable Disk Errors.
    A Disk Error will result in retries, both Hardware and Software, which often produces the data, corrected, after a delay.
    My recommendation would be to find a time when you can back up all data from the troublesome drive, and take the \[several hours] to Initialize with the "Zero all Data" option. This writes Zeroes to every data block, then does a read-after-write to check the data.
    If the Drive's error correction was required to recover the just-written zeroed data, that block is declared bad, and the drive will make a near-permanent substitution of a nearby spare block for the one found defective. This process has the effect of laundering out marginal blocks and returning the drive to "factory fresh" condition of all good blocks.

  • Adjust frame rate in iMovie?

    Have some video made on a Canon G9 digital rangefinder camera that was shot in a stop freeze frame mode instead of reg video. Is there a way to slow down the frame rate in iMovie. This clip is mixed with a bunch of still photos and other video clips shot in normal mode, and it looks a bit too jumpy.
    Thx

  • Core Audio Disk too slow or System Overload message

    Hi, I hope somebody can help me. I've seen the topics about this already posted, but my situation is a little different. I'm only playing back three tracks of recorded audio and two EXS24 sampler instruments. I have the Logic compressor on my bass track and thats it! My Disk IO meter shows no load at all as well as the audio meter. However, I'm still getting the core audio disk to slow or system overload message. I figure with a dual 2.7 G5 and 2.5 Gigs of ram I should be unstoppable. What's happening?
    By the way I'm using Logic Pro 7.1, and my sound card is a Delta 1010 from M-Audio.

  • Adjust Frame Rate

    iMovie default frame rates are 25fps for Pal or 29.97 for NTSC.
    With iMovie 09 there are a few software workarounds to get iMovie to maintain the frame rate as your original or to render an AIC file at full 50/60fps.
    I want to maintain the 50 fps as my original HD footage, but with iMovie 06 (my favoured editing package) - Can this be done ??

    Many thanks - A straight forward answer. Still wish Apple would release iMovie 6 for developers to run with and make a few tweaks as I still love it as a program over and above other editors for simple throwing together of clips!!

  • FCP Multicam - mixed frame rates & audio sync

    I created a multicam from an hour of video from three cameras and two additional sound sources.
    One camera was set to 24fps but was only used for a few shots.  Both the other cameras were set to 25fps (the only option).
    I did not include one of the audio sources in the multicam - it was a lapel mic and I figured I would use only bits of it where necessary.
    However, this audio runs at a slower speed to the multicam - exactly 4% slower, which suggests that the multicam works by dropping frames from the 25fps clips.
    The pitch is also different - making the lapel mic audio unusable if there is music in the background (it was a wedding - so there was a lot of that).
    What did I do wrong here?

    Thanks Jim. I just want to be sure there's no other solution. Almost all the footage in this feature is 24p, so editing in a 30i framework is not a good option. Here's a video comparing the difference in how FCP and Premiere resolve 29.97 footage in a 23.98 sequence: Is there really no setting or process that will have Premiere play it back smoothly?

  • Keyboard repeat rate too slow

    Hi.
    For some reason I'm unable to increase the keyboard repeat rate in Windows XP. The slider in Control Panel / Keyboard is set to the maximum, but the rate is still too slow for my taste. I've never had a problem with this setting in Windows before, so I suspect it's either a problem with the Boot Camp drivers, or some other Apple hardware related issue.
    I've also tried to bypass the Control Panel and set the repeat rate through the registry. The value in HKEYCURRENTUSER/Control Panel/Keyboard/KeyboardSpeed is 31 when the Control Panel slider is at the maximum setting. Other sites have suggested that the unit of this value is "characters per second", and that it could be increased to at least 80. Unfortunately this does nothing for me, even after rebooting. Also, the current max. rate is more like 20 characters per second (which is not fast at all); I can decrease it - using the Control Panel or the registry editor - but it won't go any higher that 20/s (by my measurements).
    I'm using a Mac Pro with Boot Camp and rEFIt (Leopard 10.5.1, Windows XP SP2, and Kubuntu 7.10 Gutsy). Keyboard is the new aluminum Apple keyboard, but I've plugged in my old Logitech keyboard too, same result.
    Any ideas?

    Hi, Warren -
    If you have a reasonable size computer store (not an Apple one) not too far away, it may be worthwhile to visit it so she can sample the feel of various brands of keyboards.
    One thing to consider is that the keyboard should be compatible with Mac keyboard startup commands - not all are.
    I like the Macally iMediaKey keyboards - their layout is not as condensed as the newer Apple keyboards, and I like the action of the keys. In particular, I also like the fact that the keyboard has a functional power key, and extra programmable keys along the top - they're very handy for starting up commonly used programs without having to consume Fkeys.

  • 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.

  • Audio too slow on laptop L515

    I have a laptop L515 satellite but the audio is too slow
    I already tried to re install drivers but the issue still persists
    please tell me what i can i do to get a better audio sound on my laptop

    Thanks Rod,
    That's good to know that the laptop speakers vary.
    So what is the best way to make the speaker sound louder
    - should we record louder
    - normalize in audition but with increased db
    - normalize in captivate with increase db
    Our concern is that if we increase the db then background sounds will be more noticeable and we would have to do more processing which might change the overall audio quality.

  • 23.976 frame rate explained

    This post was triggered from this this thread:
    http://discussions.apple.com/thread.jspa?messageID=4741388#4741388
    I just thought it best to start a new one
    Okay iSchwartz, with the speed of a flying bullet, and with help from my fellow members of the IBS (Institute of Broadcast Sound - in the UK), I think I have some answers...
    24P is indeed simply video at 24frames per second with the "P" meaning Progressive scan. Its a video format invented to be compatible with film. It also means that the footage will have more of a "film look" when its converted to TV frame rates for broadcast as it will have the same process applied to it as film footage.
    As to where 23.976 fps comes in (with regards to Logic) is rather more vague!
    (warning - the following contains some speculation!)
    As all will know because film is shot at 24fps it needs a special conversion process to be shown on an NTSC TV of 29.97fps. The process could just speed the film up but it would look funny and so they sort of duplicate some of the film's frames instead, to get the frame rate increased. The process used would result in a frame rate of 30fps so to bring it in line with the (cumbersome) NTSC frame rate they have to slow the film down slightly (by 0.1%) before they "scan" in the film's frames to make video.
    ...and guess what a 0.1% speed reduction of 24fps results in? Yes - 23.976!
    so...
    23.976 is the frame rate of the telecine machine when playing film to transfer to NTSC tv. The process involves slowing the 24fps film by 0.1% to 23.976 and applying a 2:3 pulldown picture process, resulting in NTSC's frame rate of 29.97fps
    Now the question is why would you want Logic to work in 23.976fps?
    It is possible (I don't know for sure) that when you shoot with film (ie 24fps), destined for tv that the programme is edited at 23.976, ready for the telecine process, and so this is the frame rate used during the post production process - As it is the time reference used in the edit then we need logic to work at this rate too so we're all in time.
    It is also possible that the latest HD video cameras provide a shooting frame rate of 23.976 fps so that the "slow down" process of the past is not required.
    Having said that to view the 23.976 fps pictures on telly the video needs to be converted to 30fpsDrop - or you need a display that can work at this unusual frame rate. I am not sure what the implication of all this would be for the musician "working to picture".
    One thing I would say, is that musicians are not alone in having much confusion with frame rates and time code, especially now Hi def has arrived. I would strongly advise double checking with "production", particularly the dubbing editor, if that frame rate requested ~really~ is the right one!
    I hope I haven't confused the issue even more with all that! Don't take any of this as gospel as I am still learning too. I trust someone will provide corrections and additions.

    Rohan,
    I agree in so far as the musician should not have to worry about the technical aspects of picture, but the composer is working within a team of people who have to be able to communicate effectively. the composer is also part of the production's overall workflow and so the composer's work methods can be dependent on productions.
    To answer you points individually...
    - when the telecine is created, and then sent for offline editing, it is the offline edit that you receive with the BITC or the striped LTC (rare these days) that should be your guide. obviously in the states with the confusing NTSC format, it is important to be sure what format they have used in the offline process, but ultimately it is the production facility to ensure you have a video edit that you can work to
    Your first sentence says it all. If the offline edit is in 23.976 then presumably this is what you'll get sent. I have no idea how this will get delivered as the format would not work on video tape, you wouldn't be able to view it on a standard TV either. You could view it as a quicktime movie. That is the only way I can think of.
    I agree it should be up to production to provide you with what you can work with but how far must they accommodate? I doubt anyone would be too happy providing U-matic tapes these days. For my last job I wanted QT movies on a DVD-R but I had to settle for DV tapes and capture myself. Lets face it, as technology gets cheaper and more accessible we are increasingly expected to be able to handle all those advances!
    - so the music you create can either sync to a master clock (which is rare other than word clock which is not for video syncing anyway) or simply to the QT or VHS that you have been provided with which should have standard frame rates. you simply compose your music based on that sync
    I don't know what you mean by "master clock" in this context, and as you point out word clock has no timing information at all and is irrelevant in a timecode discussion. Yes you work to the movie you've been given, but what if its using 23.976fps? If it is, it wont be on VHS - and, you wont be able to sync properly to it in Logic as Logic doesn't work with 23.976
    If production provides you with a "special copy" in say standard NTSC 29.97fps then the editors timecode will be different to yours. You wont be able to talk timecodes with them over the phone for example. For them to do this production will have to convert the footage specially for you using 3:2pulldown telecine process (so the film plays at the right speed) and I'm not sure they would pay for that!
    - the issue is more critical in the dubb, but generally 1 second of music at whatever frame rate is still 1 second of music. when you send your music in it is almost never smpte locked unless you have delivered via a timecoded DAT something which is very rare these days. basically it simply measures the sample rate and then syncs within the DAW in the dub
    1 second in NTSC's 29.97fps is 1second at 23.976fps which is 1 second in PAL's 25fps too;-) Its the number of frames within one second that has changed. The problem is the format of the movie. you can play it in QT but not on the telly and Logic doesn't have a time base to match with it. It is likely that logic will be able to follow the movie in QT (not sure of that), or "chase" it, but Logic's own smpte display will not match the movie's BITC. Indeed all of logic's time references will not match the movie's.
    when you send your music in it is almost never smpte locked unless you have delivered via a timecoded DAT something which is very rare these days. basically it simply measures the sample rate and then syncs within the DAW in the dub
    Ever heard of BWF? Bounce your finished music in logic as a WAV file and you actually get a timecode stamped "Broadcast WAV" file: a file that has the SMPTE time of where the music starts in the film. The timing info is embedded in the file. All the dub mixer has to do is press a key-command to place this file in the right place in the film. I worked this way on my last project. (Its also how logic can place any audio file into "its original recording position")
    Without using timecode I'm wondering how you tell "the dub" where the music should go in the film? - I'm genuinely curious. In the past when delivering music without timecode I would still say, in a written note for eg, the track starts at some timecode point (as referenced to the BITC for eg). This is why the composers timecode needs to be the same as the dub/editor's!
    - it is simply important for the people sending you their film to agree how many frames consitute their second. if you have a VHS playout from the offline, you should work to whatever format that VHS or DVD comes in; NTSC or PAL. it's not your job to worry about the film to offline telecine
    A nice thought in theory:-)
    It shouldn't be our job to worry about such things (bars, beats, keys and harmony are enough for me!) but we may not have the choice if we want the job!
    Don't get me wrong here Rohan. I don't profess to understanding all this stuff properly and I have never been asked to work in 23.976fps. I went down this line of enquiry to see if I needed to know about it! Perhaps you are right and production will supply a special version for the composer - but I'd like to know if this is the case as I like to have a basic grasp of the overall production process. I'd love to know of anyone who has had to work in this frame rate and how typical it is becoming (if at all).

  • 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.

  • Change h.264 frame rate

    Hey, my 2nd question of the day.
    Got some brand new HD MOVs that are 1920 x 1080, 23.98, h.264 compressor. They seem to play fine in Final Cut. I have other clips that are 1280 x 720, 59.94, h.264 compressor. These 720 clips were shot in slow motion but are not playing in slow motion in Final Cut. I tried to use DVCPro HD Frame Rate Converter but obviously didn't work. Any other way I can convert the 59 frame rate to play in slow motion?

    Use Cinema Tools and CONFORM. But, get out of the H.264 codec first. H.264 is not an editing codec.

  • Can I disable the audio pitch adjustment when using frame rate conversion?

    We have a mov file containing digitized film material with audio scanned at 25 fps (1 frame film for 1 frame video) while the film should be 18 fps.
    So both video and audio are too fast.
    Compressor provides the framerate conversion so source plays at x frames per second.
    This works well for video but the audio slowed down remains the pitch it has in the original speed. A great feature but an unwanted result in this case.
    Audio should be at a lower pitch since it was recorded too fast.
    Can we disable the pitch adjustment, when using rate conversion, so the pitch is corrected (lower) as well?

    Hi Jason
    This does sound tricky - the only other suggestion that I can add to David's is to use the smallest GOP setting you can, I'm in PAL land so the default is 12frames but I push it down to 7, this forces more I-frames into your mpeg. It makes the file size higher but in a project your length it doesn't matter. Make sure you encode your audio to .ac3 (use the Dolby 2.0 preset in compressor). Although David's limit is 7.4, if I'm not playing back on a laptop I'll set my CBR to 8Mbps (in Compressor CBR is called 'one-pass').
    Once you create your mpeg, play it back in Quicktime first to make sure there are no artifacts full screen (with Simulators reduced size sometimes artifacts exist in your orig mpeg that you may not notice).
    Also as David said, DVDSP doesn't re-encode an existing mpeg so something else must be going on. Before you re-import your new mpeg, delete your DVDSP prefs and any menu mpegs that it has created.
    If you have Toast, try just doing a Build, instead of Build & Format. This will give a VIDEO_TS folder that you can then burn in Toast. Use the Data tab and select DVD-ROM/UDF.
    If this doesn't work I don't know what will.
    Good luck!
