Disturbed Audio with long clips and speed changes.

Hello,
I experienced a strange problem in FinalCut Pro (v 6 and 7).
-I capture a clip with a Blackmagic Decklink or a DVS Pronto as Uncompressed Quicktime, 720p50 via HD-SDI with embedded audio. The clip is about 10 minutes long.
-I speed down the clip at 36% by changing the clip's speed in the sequence.
When I render the audio track, I get completely distorted audio after some minutes until the clip's end.
The problem doesn't seem to occur when I put the clip in a sequence and nest that sequence into a second one and change the nested sequence's speed.
Is that a known bug? Did anyone out there experience the same problem? Is there any technical explanation and solution?

Both Picture Safe and Title Safe are guidelines. They were developed to ensure that titles and pictures placed within these guides would be viewable on most televisions.
In the same way that no two tv's will look the same with regard to colour, there can also be a great difference in overall picture placement on the screen. Keeping titles within the safe area will help ensure that even the most poorly calibrated set will still show the entire title.
You can't convert the MP4s because you do not own the right to use them.
As for the MP3's, time to do some work and look it up. The Search function here is a great resource.

  • Color correction/effects when working with long clips

    Hi,
    First time poster!
    I'm a beginner with Adobe Premiere Pro 5.5. I'm using it right now to do some color correction on badly produced DVD's in my film collection! I was wondering if it is possible when doing color correction effects on a clip if you can apply different effects to different parts of a clip. For example - At the beginning of a clip, the scene is really bright, but, some 30 minutes later, the clip is really dark. Is it possible to darken the beginning and lighten the ending? How would you folks deal with a situation like this? Would you edit the film down to smaller parts? If so, how would you go about that?
    Thanks for the help!
    Howard

    Howard,
    Welcome to the forum.
    Along with Jon-M-Spear's suggestion (the one that I use most often too), many Effects can be Keyframed, so that they change over time. However, this does take some time, and can involve a lot of fiddling.
    If you have a long Clip, and know that you will be adding the same set of Effects, but just with different attributes, you can do one of two things, and both rely on Jon-M's method:
    You can create an Effect Preset, and apply that to all of your Cut, let's call them "sub-Clips," even though that term has other meanings, so be careful when using it. Then apply that Preset to all of those sub-Clips. Then, tweak each application of the Preset, as is needed for the individual sub-Clip.
    In a similar fashion, you can apply all necessary Effects to the first of your sub-Clips, tweak for it, as is necessary, then Rt-Click on it, chosing Copy. Now, Select all of the rest of the sub-Clips, to which you wish to apply that set of Effects, Rt-Click on them, choosing Paste Attributes, and then tweak, as needed.
    A variation on the above would be to apply the Effects to the origianal Clip, and THEN make the Cuts. Go back and tweak each individual sub-Clip.
    Good luck,

  • I have an old project with AVCHD clips and I want to import the clips again with surround sound. How can I relink the project clips to the re-imported ones without doing the project from the begining?

    I have an old project with AVCHD clips and I want to import the clips again with surround sound. How can I relink the project clips to the re-imported ones without doing the project from the begining?
    I have a sony handicam and I imported the clips to iMovie and they lost quality and converted the audio to stereo. I want to import the project to final cut X and import the AVCHD in 1080p and surround sound and export the movie in bluray. Can I relink the clips without editing everything again?
    thanks!

    Only photos taken with the iPad, copied onto it via the camera connection kit, or saved from emails/websites etc can be deleted directly on the iPad - either via the trashcan icon in the top right corner if viewing the photo in full screen, or via the icon of the box with the arrow coming out of it in thumbnail view.
    Photos that were synced from a computer are deleted by moving/removing/de-selecting them from where they were synced from and then re-syncing. If you want to remove them all then normally you could just sync an empty folder (in terms of photos) to the iPad, but as you don't want to sync at the moment you can't do that.
    You can reset the iPad back to factory settings and start from scratch with it : Settings > General > Reset > Erase All Content And Settings

  • Best practice when dealing with long clips

    I have some long clips that I want to use more than once with different in and out points. I know this can't be done so is the best practice to make duplicates of the clips and set different edit points or somehow roughly split the large clip into smaller clips and name them accordingly.

    Not certain what you think you can't do. Take a long clip and open it in the Viewer. Set In and Out points. Drop that into the Timeline. Now you can move along in the Viewer clip and set new Ins and Outs and drop that into the Timeline. Clips in the Timeline are created from the Ins and Outs you set in the Viewer.
    Is that what you want to do? If it is, I don't where making copies of the clip would work for you
    Later, if you want to match up a clip in the Timeline to that master clip, just use Match Clip (find) in the timeline to find where it correaltes to your main clip
    You can have FCE automatically create subclips at camera cut points by using DV Stop/Start Detect if that is what you're looking for

  • Audio playback is clipped and has low volume

    Hi, I'm hoping that someone can help me debug my audio problems.
    The problem is that audio playback is clipped and has low volume.
    The details of my setup are as follows:
    - An onboard soundcard (ASUS M4A78LT-M-LE motherboard), identified as Intel HDA in dmesg:
    description: Audio device
    product: SBx00 Azalia (Intel HDA)
    vendor: ATI Technologies Inc
    physical id: 14.2
    bus info: pci@0000:00:14.2
    version: 00
    width: 64 bits
    clock: 33MHz
    capabilities: pm bus_master cap_list
    configuration: driver=snd_hda_intel latency=64
    resources: irq:16 memory:f9ff4000-f9ff7fff
    - ALSA (snd_hda_intel driver) and Pulseaudio
    My ALSA mixer settings (which were used in the recording shown in this post) are at pastebin.
    The mixer settings were chosen so that all "dB gain" is 0.00 for all columns in alsamixer.
    Recording an MP3 (played at full volume) from the Stereo Mixer source in audacity I gives output which looks clipped and has low volume (link).
    This occurs with any MP3 and any other sound source (Youtube in Chromium, etc.)
    The problem does not occur when I boot into Windows XP, so it doesn't seem to be a hardware problem.
    I'm also attaching a screenshot of my alsamixer playback screen for the soundcard (link)
    Thanks for any assistance!

    Hi,
    I have the same problem since December 2011 with a similar Mainboard (Asus M4A78T-E).
    Did you resolve your problem?

    The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
    1. You don't own another Mac.
    If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
    If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    2. You do own another Mac.
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
    After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
    If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
    If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.

  • IPad2 with iOS 6 and it changed my passcode.  Why?

    I just updated my iPad2 with iOS 6 and it changed my passcode.  What gives and why did it do that?  It has locked me out with no way to shut it down.  Any ideas? 

    iOS 6 did not change your passcode.
    If you have forgotten the passcode then you will need to restore your iPad from the same computer that you most recently synced to.
    Read this: http://support.apple.com/kb/ht1212
    If you can't do the restore then you will need to try recovery mode.

  • Recommendation for case with a clip and protection on all sides, snug fit.

    I'm looking for a case with protection on all sides, with a clip, with a snug fit -- i.e., not designed for ever make / model (not one size fits all). I bought the case at the Apple store with a clip and a snap, but the top of the phone is mostly unprotected (uncovered) and I don't like the flap with the snap because it does not close correctly unless I stop what I'm doing and look at it to make sure the snap lines up (i.e., the flap has too much extra material and does not line up automatically with the snap).

    Otterbox Defender case which provides excellent protection and probably the best protection of all available cases which includes a clip.

  • Log and transfer causes FCP to crash with long clips

    Hi. I am trying to import a few 2 hour+ clips using Log and Transfer from my Sony NX5. Once the destination clip has reached approx 60GB, FCP crashes every time. There is plenty of disk space left.
    I have tried trashing preferences and also changing scratch disks. I am turned off time machine. I am really worried that I wont be able to get this footage onto my machine.
    Any ideas?
    Thanks

    In the end Clipwrap saved the day on this project.
    This did happen to me again though on yet another project, where the files were around an hour long this time. In the end I got it to work, not sure the solution but tried the following:
    - Selected a different easy setup (choose PAL) - this fixed the problem for a colleague of mine, even though it doesn't seem logical
    - Used my internal drive as a scratch disk instead of my firewire drive (normally this is not a problem)
    I haven't tried this with the really long clips, as Clipwrap saved me.
    Many thanks for suggestions.

  • Audio Sync Issues with Long Clip

    I am about to start editing a multi-cam concert shot on 5 DVX100 cameras without Jam sync TC.
    In the past i have had issues with sync when digitizing long clips. is this still the case with FCP? Can i safely digitize 45-60min clips?
    I am using a Pro-sumer Panasonic MiniDV Deck for capture. (it is on FCP's 'suppported devices' list)
    on the avid i would digitize full tapes to make the Grouping (Multi-clipping) much faster. I want to avoid capturing a bunch of small clips on FCP and then sync them individually.
    any info is greatly appreciated.

    DEAD ON THE MONEY. And yes, you can do it with the HVX. This is a really cool thing. There is a gotcha-- the dvx and hvx have an internal battery that allows for the retention of things like timecode when the camera is off. You gotta be sure that battery is charged. And the way you charge it is to attach the ac adaptor and plug it into the wall with the camera off for an hour or two.
    Once all the cameras are running with freerun code, you can swap batteries etc and the code just keeps going.
    Another thing- when you set up your camera pile, you've got to stand a couple of feet in front of the pile when you hit the remote so that the signal gets to all the cameras.

  • Slow motion and speed changes blurry jittery - SOLUTION!

    I Have had a few issues with slo mo and sped up stuff going blurry or jittery on me.
    This is from HD from a HC3 down converted (camera does this) to SD anamorphic (pal).
    I think i have found the solution - and welcome any exra content from more experienced heads than mine.
    Of course there are limitations to how far you can slo mo before you get the jitters - anyway- here is my hot tip!
    Change your speed (fit to fill , or modify speed) of the clip in the canvas (leaners - watch your sound timing - it can be thrown off if you have locked off ausio tracks) open up your clip from the canvas by double cliking it, tap the motion tab, cross the motion blur box - adjust the sample setting from 4 to 32 (i dont know exactly what this does but this is the key!, drop motion blur down to 0 %.
    RENDER! voila! This has quickly resulted in some speed changed clips that hold their form rather nicely (no blurring or strobing , jitters etc - that have plagued me in the past - i'm doing lots of sport stuff where speed changes are common)
    Hope this helps other relative newbs out there! And if anyone would care to comment on why this works i would be all ears!

    I know what you mean, I end up with an extra frame if I set an in and out point then insert/overwrite replace or superimpose.
    I find the quickest work flow is to
    0. mark the in point at start of clip
    1. copy the clip, command c
    2. go to the end of the sequence, end
    3. paste clip
    4. change speed, look at duration of clip, change speed %, command j
    5. change duration back to original duration,
    6. cut clip from end of time line,
    7. return to in point and paste clip.
    I find this does give me control over the clip, does not affect the timeline and is frame accurate.
    I agree you should be able to change the clip speed without affecting the duration.
    The alternative is as Andy described, fit to fill, here is an alternitive way of doing/describing this process;
    adjust the out point of the clip to the new point you want,
    move the clip out of the space on the timeline where you want the clip with the speed change to go,
    place the CTI in the space where you want the new clip to go,
    double click on the clip you want to adjust, opening it in the viewer,
    drag the clip from the viewer to the canvas and the fit to fill option will appear along with all of the other options,
    this will also do what you want, I believe there is no one click solution.
    Someone please prove me wrong! I would love to be able to "command j" in to the speed dialog box, click on a check box that says keep duration or in/out points and simply change the duration.

  • How can I use all tracks from multi-channel source audio with Multicam clips?

    I cannot figure this out. Working in Premiere I'm prepping for a 2 camera show, with typically 4 to 6 track dual-system audio recorded by the sound guy. I can sync, and make multicam clips any number of ways–whether sync by timecode, sync by audio, or eyeballing–but whenever I edit using the MC clip, Premiere mixes down all the audio channels into a stereo single track, and I cannot pick and choose which audio track from the original to use. With 2-5 people mic'd on lavs, I need to be able to choose which audio is either cut in or heard at any given shot.
    Is there any way to have control in multicam clips over which track of audio gets edited into the timeline, or even: that all tracks of audio get cut in? It's very important for the editors to be able to see waveform (which also disappears for some reason in the mixdown) and pick and choose which audio is heard?
    I'm sure this might be a simple fix, but I cannot get my head around it for workflow purposes for my assistant editors. We need to use multicam, but this audio thing is driving all of us crazy. None of us can figure out how to have a multicam clip and use it with control over what audio is cut in.

    True, but what I need to be able to do is have my multicam sequence in the source monitor, and cut into my working sequence with either just the audio I need from the sound guy's multi-channel WAV, OR cut in all the sound and from then I can just enable or disable what I need or don't need. But also be able to match back to the Multicam source from my working sequence.
    I don't want to have to open the synced sequence, and razor blade the things I need and have to copy and paste into my working sequence in order to have the full spectrum of my multi-channel mono lav WAV files...with their waveforms visible.
    Essentially, I want my Multicam clips to load in the source monitor, and the ability to cut them into the working sequence without it mixing down the audio into a single track with no visible waveform–which is what it is doing currently. Can I choose to edit in either ALL of the tracks of the WAV file along with the camera shot I want, or control which audio gets cut in?

  • Advanced Button with Movie Clip and Fading

    Problem: I'm trying to create a bottun that when you roll
    over it it plays a movie clip and also fades in and out on roll
    out. It is similiar to the three main navigating buttons on the
    following site.
    http://www.fjcruiser.ca/
    the buttons with the compasses that appear are the ones I am
    talking about.
    I already know how to make buttons, I just can't figure out
    the actionscripting to load the movie and also fade in and fade out
    according to roll over and roll out.
    Please help. Thank everyone.

    Amazingly, I actually know exactly how to do this. And it
    only requires about 4 lines of code in the _root layer and on the
    button.
    Instead of having the rollover load an external movie, you
    want the have the rollover execute an on(enterFrame) function that
    tells each newly entered frame of your movie to check to make sure
    the mouse is still on the button, and if not, send the movie
    playhead backwards.
    So, put that sampleMovie right on the stage with the button.
    Then write the code in the _root so that says: as long as the mouse
    is over the button, the movie will advance to nextFrame(). When it
    gets to the next frame, again the code checks to see if the mouse
    is on the button, if so, the movie is instruct to go one more next
    frame (which is tweening the fade, right?) again, over and over
    until the stop() at the last frame. But, if while while entering a
    frame, the code finds that the mouse is no longer over the button,
    it does the same thing but this time instructs prevFrame(), and so
    on, going prevFrame (backwards, in other words) as long as the
    mouse is not on the button.
    The result of the above is a gradual fade in and out,
    depending on whether the mouse is hovering. This, as opposed to an
    abrupt disappearing graphic on(rollOut).
    Click the below link for the .fla that demonstrates this
    technique (which, by the way, I learned from Joshua Davis'
    excellent book, "flash to the core". Check it out at Amazon, or
    wherever. Lots of cool tricks).
