Audio clip dropping frames/skipping

I opened up a project in Premiere Pro CC, and the audio waveforms were gone although the track was enabled. When I opened the audio track in the source monitor, the entire audio clip was completely compressed from 3:04 to 1:33 and was skipping pretty badly when I played it. I tried converting it to mp3 and aiff but with no luck. How do I fix this?

The audio should be 48k, 16 bit, stereo (or mono). But the sample rate should be 48k.
32-bit floating point refers to video rendering, not audio.
What school is this, BTW? And tell us about the networking configuration, please, so we can try to figure out your dropped frames issue.

Digitizing Pre-Logged Clips: Drop Frame/Non-Drop Frame Discrepency

I have about 100hrs of DV NTSC footage that has been logged and now I need to capture it.
Everything seemed good to go:
• I ctrl+click the clip intended to capture
• Select 'batch capture' (it initializes)
• Settings are (apple setting) DV NTSC 48kHz
• I click okay and I get an error message that reads:
"WARNING: You are about to capture drop-frame media to a non-drop frame clip. If you proceed, you may experience changes in logged in and out points, problems relinking media, or removal of master clip relationships."
Now, the setting noted above is set at 29.97 not 30.
I tried to see if there was anything I could select/deselect in the logged clips and came up dry.
I made duplicated the apple setting and changed the fps to 30. This yielded no error message but did on the second clip I tried.
Does anyone have any idea on how I should be troubleshooting this?
Due to the high volume of footage, and workflow schedule, I'd really rather not screw this up.
I turn to you my faithful FCP gurus.
Thanks.
Ian
p.s. I'm running FCP v.5.1.4

Just check your timecode accuracy before you get any further... i.e. does the timecode in the captured clip match the code that's on the tape. If so, you're good to go on... if not, I'd recapture using the proper TC... it's pretty easy if you do it from the tape in the Log and Capture window.

Trouble loading audio clips after frame 1

Hey, everyone!
The project I'm working on consists of a bunch of pages, each with narration. Each page is a separate frame on my main timeline. Due to all kinds of issues I was having, I am now loading in the audio via actionscript, rather than placing an instance of it into an object and going from there.
The issue I am now having is that when I tried to simulate a download, the movie would sit on frame zero until all audio was loaded, so it took a long time to get to my preloader, and by then the movie was just about finished loading. It was suggsted that I uncheck "export at frame 1" on my audio files, but now I am getting errors that I am making a call to a possibly undefined method (random audio file name of choice).
If I am loading my my audio via actionscript, do I have to load it all in on frame 1? And if so, is there any way for my movie to get to my preloader before trying to load things?
I have also tried setting my publish settings to export my classes on frame 2 or 3, in the hopes of it getting as far as my preloader before stopping, but no luck so far.
Any ideas?

I'm not sure I understand that last part --
Here's my setup:
I have my raw audio files, which are each linked to separate classes, named Frame1, Frame2, etc. Those classes are then called from separate movieclips (which also contain some actionscript to cue things in the movie at the proper time, etc).
So, do I put every movie clip that contains the call to the classes (the movieclips that are actually used in the project) on frame 1 (or 2, or whichever frame I have it exporting classes from), or do I put all the raw audio clips on that frame, or do I just write in code to have random varables call in each class name...?

Using cs3. Clips dropping frames. When I import m2t video from my focus inhancements fs-4hd

The 2 gb. limit creates several clips and the clips don't join together correctly. the end of each clip is missing 4 frames of audio and 1 frame of video. This makes it impossible to sync to video tracks together. Am I alone with this problem? Would Cs5 correct it?

Yes exactly. Using the original files to edit with can make your editing process verrryy slow especially on a laptop.
Forget about H.264 for editing- a good codec for other purposes but not for editing in Final Cut.
Don't worry about losing image quality when you import and transcode into ProRes - you aren't 'sacrificing' image quality, you're only converting (transcoding) into this codec to edit with-- to make editing faster and more efficient on your CPU... This is what he means by that. The original files will still be there - don't worry they won't be slaughtered
ProRes is the most FCP friendly codec for editing - it's an Apple codec that gives you high playback quality without using a ton of CPU, and was pretty much designed for FCP. You should find that transcoding your material into this codec will eliminate the sluggishness you've described.
FCPX gives you the option for ProRes optimized or ProRes proxy when you import your media - both are good for your purposes, but proxy is probably the best for you since you are on a laptop . Fastest to edit with, with slightly less image quality (again - only while editing!)
Then, whenever you're done editing and are ready to export back into high quality - just go into your preferences menu and click Original/optimized media and it will switch over for you. You can then export in high quality.
FCPX as much as I hate it - makes the transcoding procress very easy.
good luck.
the original media will still be retained, all you have to do is click a button when you are done editing and export your project with high quality media at the very end.

Different Audio rates & audio formats = drop frames?

I´m getting a lot of drop frame errors during playback in the time line.
Now that I want to print my movie to tape the drop frames of course disturb this process, making it impossible.
I noticed that I have material with different audio rates and audio formats. Could this cause it and how do I make a conversion so that all of my audio is the same rate & format.
Audio captured with my camcorder is: 48KHz, 16-bit integer.
CD music in time line is: 44.1KHz, 16-bit integer.
Timeline is: 48KHz, 32-bit floating point
(The things that FCP suggests to do when drop frames occur; turning RT to Safe, buying a faster computer etc. havn´t helped, so the problem must be somewhere else)

You could try exporting your sequence as a self contained QuickTime Movie. This would give you one file with one set of rates and formats. Be sure to set up the export for 48Khz 16 bit. Once that's done, import the file back to your project, place it in a new sequence and try printing that to tape.
If you're just concerned with getting smooth playback in the timeline you could also try doing an audio mixdown. This is a good thing to do before printing to tape as well.

Final Cut Pro X Speeding Up Clip Dropped Frames

Hello there!
I record Xbox 360 gameplay through a Hauppauge HD PVR into EyeTV3. I then export those clips using EyeTV3. Then, I import those clips into Final Cut Pro X. In the past, FCPX used to work through these clips incredibly fast and I never had any problems changing the speed in the timeline. Now, however, FCPX runs really slow, sometimes crashes upon startup, and most annoyingly, drops frames...a lot. I import the file and put it in the timeline, and even without changing the speed, it often doesn't even render the whole clip, but rather just appears to 'miss' 3 or 4 frames, which is very annoying. It gets even worse when I change the speed of the clip (namely, speed it up). I know it is not an EyeTV3 problem, because I watch the clips just fine after exporting in QuickTime. I have tried exporting as H.264 an HD 720P, but nothing seems to work. And I don't understand why it used to work flawlessly until now. It is really upsetting and I am at a loss as to how to fix the problem. All help would be appreciated. Thank you very much.

Drop Frame being read as Non-Drop Frame

Hey,
I'm working in FCP HD 5.1.4 and our guys are shooting audio at drop frame, and video at drop frame, and yet when we import the media into FCP, the Video is in Drop frame, but the audio appears to be Non-drop so we're getting BAD sync (some clips 30 seconds, others up to a min.). We're using TOD T/C and it's really important that we convert it cuz we'll shoot 8 hr days, and the first few clips arn't that bad but after so many hours, the sync gets worse and worse.
We're using XDCAM Sony PDW-1500 deck for the video transfer and the audio is BWFs from an external Audio receiver, then it's backed up on lacie drives (prob using compressor) then we're syncing in FCP.
Any thoughts?
Fraser

FraserPost, according to Apple in the Late-breaking FCP news PDF on pg.4, Broadcast Wave Audio Files imported will always be interpreted with non-drop frame TC.
Highlight the clip in the bin, choose Modify Menu option and choose Timecode. You can then change it to drop frame in the options panel.
Then your material should synch up.
For future reference but still notable, if you import an aiff, mp3 or another type of audio file without TC, the file will create TC dictated by the Sequence preset setting. This I found out the hard way. One has to shut down FCP and start it up again for the change to take effect on material imported.

Non Drop frame capture causing out of sync clip?

Hi, All,
I've been having trouble with sync issues on an hour long tape capture.
The material was captured from a Canon consumer DV cam (z80) using firewire into my powerbook g4. (The material on the dv tape was originally recorded in Video 8mm and transfered to the Canon via firewire from a modern Sony Digital 8 camera.)
The sync on the DV tape looks fine when I play it back through the Canon camera. So I'm guessing that I might be losing sync because the camera is dropping frames that don't want to be dropped. I tried to change the video capture settings to non drop frame (in the device control tab of FCP5's audio video settings preference window,) but as soon as I start the capture from the canon, the settings on my log capture window automatically revert back to drop frame. (I don't know this for a fact, but I do notice that the ":" in the timecode box turns back to ";" every time I start the capture.
Does this sound like it is, in fact, a drop frame problem? And if so, is there any hope of getting a canon consumer camcorder to capture at non drop frame rates?

Well, after trying most of the suggestions here, I did find a reasonably hassle free workaround to capturing the hour and fifteen minute footage of 8 bit 32 kHz video to FCP with minimal sync slippage over the length of the footage.
I finally gave up on capturing the material in FCP and instead hooked the canon z80 up to an old version of Toast Platinum 6 I had on my computer. Toast creates a raw quicktime movie file with the extension .dv. Toast then allows you to edit that quicktime file, add chapters, button pictures, etc. thereby making a new file to replace the raw QT it first created. After some experimentation, I discovered that the original raw QT file Toast creates can simply be dragged intact to the FCP browser window, where it becomes a clip with minimal sync problems. I would caution against trying to use the second improved QT file that Toast creates after you've edited your file, as this second QT movie seems less stable than the raw one it first creates.
A final caveat for Toast users. Make sure you set the preferences so that they don't DELETE the original file it creates. There are settings that will tell Toast to do just that either After a Day, After a Week, When You Close the Program or Never. I'd set that to Never, since it can be highly unpleasant to discover that your program has deleted the very file you were planning to work with.
Hope this is of some help.
Thanks to all who pitched in and offered suggestions. Your help has been invaluable!
I now mark this issue Solved. Or at least as Solved as I plan to get it!

Drop frame video to non-drop frame clip warning (again)

So my most recent search of why this warning comes up reveals no good answers (unless someone can point me to a thread I overlooked...cuz I can't narrow it down without getting threads about folks who have gotten dropped frames during capture, which isn't the same situation)...
I shoot on an XL2 (drop frame) and capture with a DSR-11. Once in a while I will finish going through log and capture (in the log and capture window), setting ins, outs, etc. but I go to batch capture and it gives me the warning. All my ins/outs have semi-colons, I haven't changed the setting on my camera since I started using it more than 18 months ago, and it doesn't happen all the time. I do have the "abort capture on dropped frames" box unchecked as well (if that matters).
99.99% of the time, I've captured and there's no problems with syncing or anything. Thoughts?
Thanks,
Jonathan

If I recall right someone suggest to have your tape playing while opening Log and Capture, but I might recall wrong
I already have the "Abort on dropped frames" and "report dropped frames" unchecked.
Don't be mistaken: Dropped frames are a totally different issue from non-drop and drop frame timecode.
Drop frame timecode drops (or better: skips) timcodenumbers while counting the videoframes. That is a system to compensate for the 29,97 frames per second in order to calculate the correct length of a clip.
Dropped frames (as in "Abort on dropped frames" and "report dropped frames") is an error. Due to some reason the hardware isn't capable to record/digitize every single videoframe to your harddisk. e.g. Your captured file will have 2000 frames, while your footage on tape had 2003. Three frames were dropped then during capture. And your video will noticeble stutter at these points.
So I'd strongly recommend to do check the "Abort on dropped frames" and "report dropped frames"-options. You don't want stuttering video do you. So if your hardware couldn't handle the videofeed somehow, it would resp. abort capture or warn you that it happened.

Dropped frame warning after adding 3d video transition between 2 clips....

Hi all,
I have the MBP in signature and after making a very short sequence with 2 small clips (obtained by the same master clip, from/on my SSD, that is 640x480 / 10fps with AppleOPEN DML codec) between which I insert a 3D video transition (cross zoom), if I press the space bar for preview (with unlimited RT setting + dynamic setting for playback and frame quality) I get the dropped frame warning as soon as the playhead reaches the 3D transition in the playtime....Is this normal even with my very new MBP specs???
Note that I am currently on battery and not on charger (--> the GT330M is gently underclocked).
May you please advise?
Thanks
Emanuele

Hey there,
First of all, FCE doesn't support your media. You should really use something like the free [MPEG Streamclip|http://www.squared5.com> to convert it to DV-NTSC with a frame size of 720x480, a frame rate of 29.97, and audio set to Uncompressed Stereo 48kHz. Edit the media in a DV-NTSC sequence within FCE.
After applying almost any effect you'll need to render it out to view it in real time. The shortcut is Option-R.

FCP X drops frames resulting in thousands of clips

I have a Mac Pro, 2 x 2.66 GHZ 6-Core Intel Xeon machine with 24 GB of 1333 MHZ DDR3 memory.
I have both miniDV videotapes recorded on camcorders as well as on JVC recorder. I also have S-VHS videotapes recorded on the JVC recorder (which is a dual recorder, with the miniDV deck on the left and S-VHS deck on the right)
Whenever I try to import video from either deck (or from a Canon Elura camcorder) into FCP X, I get thousands of separate clips ranging from a few tenths of a second in length to 20 seconds or so in length. When these clips are loaded into the timeline, there is a video and audio stutter whenever the playback cursor crosses between adjacent clips, indicating that a frame or two or more has been dropped. Making a compound clip is no help, the stuttering due to dropped frames persists. This makes it completely impossible to edit since no clip is long enough to be usable. The dropped frames seem to be due to the program, not the cameras, tape deck or videotapes since the problem occurs across all camera platforms as well as the two videotape formats. It's as if FCP X has a hair trigger in identifying some variance in frame rates that it judges to be a dropped frame, and immediately terminates the import of that little clip and goes on to the next import, only to repeat the same process THOUSANDS OF TIMES. The problem persists whether I record imports to my SSD startup disk, to my internal RAID, or to peripheral disks.
This did not happen in previous versions of FCP using the exact same video equipment and tape formats but a different computer. There seems to be no way to tell FCP X to ignore any variation of time code and I'm concerned that this problem will render my current equipment and videotapes worthless.
Has anyone else had this problem to this degree? I've searched other threads on similar issues of a minor nature (separate clips every few minutes), and I've tried all the recommended maneuvers. I've never seen anything discussed about the type of problem I'm having.
Does anyone have any ideas?
Thanks in advance.

Russ, thanks for your reply. It's unclear how joining clip fragments together with Streamclip would be any different than joining the clip fragments together in a new compound clip.?
Luis, bom dia
There appear to be no timecode breaks in the tapes. The duration of some of the shots is several minutes and when I watch the timecode display on the decks or on the camcorder, it appears to run smoothly. So any timecode break must be a millisecond or two. And for some reason, QuickTime gives an error message when I try to set up a new movie recording: "The operation could not be completed."

Is skipping and stuttering the famed Dropped Frames...

Been pulling hair ever since upping to QT 7.0.3 and FCP 5.0.3. All of a sudden my former 4.5 clips are acting crazy in 5. Even when I just open them in QT the ones captured since updates act crazy. Old clips play fine. Did the 7.0.1 reInstall, dumped QT preferences, but still get stuttering action. JUST curious if this is the famed demonic dropped frame symptom?

Open the clips in FCP, and play them frame by frame over the skipping parts. Look at the timecode numbers. Do they jump as well? If so...dropped frames.

How to delete the transparent frames that Pluraleyes adds to replaced audio clips in an event ?

Hi there,
I have a workflow issue working with Pluraleyes 3 and FCPX.
MY CONTEXT
So I imported all my clips into FCPX (about 300 from camera 1, about 300 from camera 2 and separate audio which ran almost with only very few interruptions on set).
I synced everything with PE which gives me back the following :
1. a new Event with replaced audio clips.
2. a new Event with one giant multicam clip.
3. a new project completely synced BUT with the non-replaced audio clips
MY PROBLEMS
1. Problem is that the clips have additional transparent frames before and after their actual video (i.e. PE makes new clips from video and longer bits of audio that do not begin/end at the same time).
2. The giant multicam clip has plenty of chunks where audio was recorded but where no video was.
MY QUESTIONS
PE has created plenty of useless clip lengths. How can I get rid of them with some batch process ?
OR if I say that another way
How can I create an EVENT that contains clips with the exact same length as the originals, only with the corresponding audio replaced ? (Please remind that I have LOTS of clips)
Moreover, the clips within the new events created by PE have (not surprisingly) lost all keywords I gave to the clips before syncing with PE. Is there any way to fix this ?
Thank you so much because it feels like PE's job is kinda useless :-/

It's the Shift key. It's not a button. It's shifts from lower case to upper case when typing. It's been called the Shift key since the 19th century.

Capture on the fly dropped frame aborted capture - clip gone forever???

I foolishly set up my Macbook pro to capture the video feed live from an HVX200 camera via firewire... THE clutch interview for a client... Lo: what happens but halfway through the interview, capture aborts and error message reads "capture aborted due to dropped frames".
It's an investigative journalism project, with a hostile interview subject, so no do-overs possible.
Clip not showing up in capture scratch or anywhere else.
My question is: has anyone had any luck rescuing an incomplete clip like this? The hard drive was churning, doing computerlike things, writing, so the information is there somewhere. It's just that the "pointers" or "handles" of the clip are gone. I know with IBM/Avid there's an attic where you can get to weird and/or incomplete files - is there anything like that with MAC/Final cut? Or is this setup "all or nothing"?
Maybe someone knows about a program that can recover incomplete data, good for MAC?
I know, shame on me for capturing straight to computer - I'll never do that again.
thanks!
Jeremy

has anyone had any luck rescuing an incomplete clip like this?
Nope. The file failed to complete...QT/FCP didn't get a chance to write the end code for the clip, so it is unusable.
I know with IBM/Avid there's an attic where you can get to weird and/or incomplete files
The ATTIC in Avid terms is the same as AUTOSAVE in FCP...it saves a backup of the project bins, not the media. Not sure about the IBM attic...
I don't know of anyone having luck recovering a file that has been aborted like this. And this happens to more people that we'd like to see. Capturing one-of-a-time events straight to computer with no backup. Bombout.

"Capturing drop-frame media into a non-drop frame clip" error message

I've logged tapes from what will partly be a 3-camera multi-clip project, and have begun to batch capture.
Logged all but one tape some weeks ago, and captured one tape at the time.
Went to batch capture the balance, today. First tape capture went fine. On trying to capture the next tape in the batch I'm getting this message as FCP begins the process:
WARNING: You are about to capture drop-frame media to a non drop-frame clip. If you proceed, you may experience changes in logged in and out points, problems relinking media, or removal of master clip relationships.
In analyzing the situation, the only reason I can think of for the error message is that some of the reels were logged on a DSR-11 that had been set to NON drop-frame, and for which I didn't have the remote control to change the setting.
I haven't run into this while capturing other clips, but those may have been captured via a different deck that does only drop-frame.
So, I'm looking at next steps:
1: Capture anyway and possibly regret that I did that.
(One person on another list reported the same problem, that he had ignored it without any obvious complications.)
2: Relog all the problem clips using my current deck, speeding up the process by using the "go to" window to drive the tape to the existing in and out points and then marking i/o's...
Or...
Suggestions?
Thanks,
Ted.

We've been seeing this stupid error message since v3 and it's never mattered in the slightest. It is always incorrect, anyway. The clips are always drop and the sequences are always drop. It's an FCP programming glitch/bug/screwup. Someday they may or may not fix the mechanism that triggers the warning.
