Dropping frames on my software only

Final Cut Pro X 10.8, on my laptop, keeps dropping frames from the footage imported from my hardrive. When I tried other computers with fcpx 10.8, same footage from same hardrive, no frames were dropped and worked perfectly. BUT I have to work from my laptop. I need to find out the cause! I have never had any issues before with my software.

Many laptops use a 5400 rpm disc which can choke video especially HD content or your drive may be more than 80% used.

Dropped frames - iMovie vs FCE only from Canon, not Sony

I have tapes shot on my new Canon Elura 100, SD, that import without complaint into iMovie but show lots of dropped frames in Final Cut Express. Imports from by onld Sony TRV never have a problem. Any idea what is going on?
Note - I used a Sony TRV-30 for years without a problem. I just picked up a Canon Elura 100. Now I get dropped frames all over the place on FCE import for tapes shot with the Canon. Out of interest I tried importing the tape shot on the Canon using my old Sony and I get the same problem. Tapes shot on the Sony have no problem. So evidently there is something on the Canon recorded tapes FCE does not like. The playback appears fine. iMovie import goes without a hitch. FCE I get a dropped frames notice and there are pauses in the playback of the imported video.

I rechecked and saw I was also starting to get dropped frames with the Sony, something I had not seen in years. Evidently there is something in my system now (perhaps 10.4.9?) that FCE2 does not like. I rebooted to an older installatioin of 10.3.9 and now both cameras are coming in without dropped frames.
Note: there were other Firewire devices connected, but not powered up.
I did not try changing the setup. Once I was in 10.3.9 everything came in.

Dropped frames on Xserve RAID upgraded w/750GB drives.

I'm capturing in 10-bit uncompressed standard definition 720x480. I just upgraded one side of my Apple XRAID, (connected directly via fibre channel) with seven, 750GB hard drives from Apple, drives designed for the XRAID, (came with there own sleds.)
Current Xserve RAID firmware version is at version 1.5.1/1.51c
Before the upgraded drives, no issues with dropped frames, (drives 1-7) the other side of the same RAID has no problems, (currently running 250GB drives, drives 8-14.) All sleds are populated with drives of the same capacity, (respective to each side.)
The drives were formated using the Xserve RAID Admin software and mounted using Apples Disk Utilities, Journaling turned off. The final formated capacity of the RAID on drives 1-7 is 4.1TB.
When I capture to the drives on the upgrade side, I get dropped frames. When capturing to the other side, no issues, works great. I checked the settings for performance and they are the same for both sides, as follows:
Use Controller Write Cashe - ON
Allow Host Cashe Flushing - OFF
Use Drive Write Cashe - ON
Use Steady Streaming Mode - OFF
Read Prefetch: 128 stripes (8 MB/disk)
My capture box is an AJA I/o and has never given me dropped frames till now, but only on the side of the RAID that has the new 750GB drives. I also have another RAID that uses 500GB drives on both sides and it work just fine as well, (no dropped frames) using the same performance settings in XRAID utilities.
Any suggestion on why these new Apple drives modules are dropping frame would be very much appreciate. Again 7 new 750GB drives from Apple w/sleds having dropped frame issues.

I'm capturing in 10-bit to avoid loss of quality from analog sources like BetaCam SP as well as line 21 must be part of the captured file, because it contains line 21 for captioning. Eight bit has a banding issue that I can't have in the final product and 10-bit doesn't have this issue.
Source quality is maintained completely when working in 10-bit uncompressed, as well as the captioning data that I need, which is stripped out of the captured video latter. Captioning software can read line 21 of the raster area, of the captured file.
Source video is from BetaCam SP, DVC Pro and DVCam.
The RAID is an Apple Xserve RAID, connected via Fibre channel directly, (no xsan.)
I also create high quality QuickTime Streaming files from these source files, the higher the quality of the source video the the better the streaming files look when created.
I have never had any problem capturing till I installed these new drives from Apple.
The RAID is as stated above, is an Apple Xserve RAID, connect via a fibre channel card in a Mac Pro 3.0GHz tower, (no xsan is used, due to connecting directly to the XRAID.)

Dropped frames from XDCAM EX HD (1080/24p) - Seems like a bug in FCP 6.

We're editing XDCAM EX HD (1080/24p) using the built in easy setup and dedicated built in drives as scratch disks. We have run all software updates and have the latest builds of final cut...
We keep on experiencing dropped frames on playback, but only on our NEW 8 core Mac Pro not on any of our other Mac's including our MacBook's.
Through a painful process of elimination, we found out that if you go to System Settings/Playback Control and you switch Gamma Correction from Accurate to Approximate it solves the problem. We have no idea why and would love an answer from Apple on this.
Moreover is this a bug or do we need to amend something on our system. As a note we've already matched pairs on the RAM and done all the other obvious stuff.
Regards
Daniel

Having the same issue with same format footage (1080/24p), the proposed solution works (a little). I can definitely playback a longer duration but it still drops frames. Even when putting a filter on and rendering it still drops frames.

Dropped frames only on xserve raid

dropped frames only on xserve raid
i'm not able to capture on xserve raid without dropped frames. tihis was a working sytem bud one morning it dosn't work. i capture on mac pro internal drives or external fw drives without problems.
the xserve raid is new formated in raid level5 [mac os extended journaled and striped in raid 0 extended] and the risult of kona system test are 178mb/sec write and 167mb/sec read.
must bee enought for 8bit uncompressed pal, no? also if i divide the stripe set the system dosn't work on both controler. i tried also to change the fibrechannel cables!
i checked also the fibrechannel card with expansion slot utility and the message is that runns at maximum speed.
there are no error message on raid admin, the xserve raid appears ok.
i'm shure that the fcp settings are ok, i know the list that regard dropped frames from apple.
i'm desperate, can you help?
thanks jochen
system:
mac pro 2x3ghz-5gb ram(from apple and the hardware test on the system dvd is ok)
osx 10.4.10
fibre channel card: lsilogic firmware 1.2.18.0 in slot 4
xserve raid 15x250gb firmware 1.5.1/ 151c
aja io (driver 3.0)
raid admin 1.5.1 (diver 1.0)
fcp 5.1.4

I'm guessing conditioning is the same as optimization, but I can't find anything about it in the help documentation. I ran another capture test today with no problems.
An interesting side event is that when I started experiencing dropped frames I ran the Kona System Test utility to verify write and read speeds. It wouldn't run (no write or read) on my RAID. I tried it on my Firewire drives with no problems. I discovered that in the Kona System Test preferences there is a choice of I/O API for Macintosh or Unix. When switching to the Unix I/O API the test ran fine with expected read and write speeds reported. I've used the Kona utility in the past without having to change that setting. I sent an inquiry to AJA.

MSI VOX - MSIPVS (only cd); dropped frames in other programs;

I have dell inspirion 11000 (512mb, celeron 2,GHz) and msi vox USB TV tuner.
I have two problems.
In MSIPVS I can only select cd audio for audio output , but I have only mic in input on my computer. I guess this problem is in connection with the sound card on my lap top. I would like to know, if anyone was in the similar situation and how he managed to get out of this problem.
Second problem is probably in connection with msi vox driver. I am able to get preview only from IUVCR and MSIVPS. I can capture sound and video only from IUVCR since this program allows me to select microphone for audio input. But during the capturing I have a lot of dropped frames (around 70% ... my CPU usage is very small, disc fragmented .... ). Other programs just don't work.
Please HELP ME! ;-)
Thank you in advance

Could be the memory, but it's hard to tell.
It may be a problem with reading the timecode from the camera.
Some things to try:
You could try to capture now and capture the entire tape with device control on.
Turn device control off and capture now (this will not allow you to recapture footage based on timecode)
If you are capturing to your internal drive where your operating system is running on and have journaling enabled, this could be fouling up the capture process. To see if you have journaling on go to:
Applications->Utilities->Disk Utilities
select the drive you are capturing to
click the select the File Menu and see if the journaling submenu says enable journaling or disable journaling. If it says disable, then the drive is journaled.
Capturing to a FileVault Volume will slow down the capture process and probably causes dropped frames.
Reboot the computer and hold the right shift key down to start in safe mode. If you have multiple users, hold the shift key down when logging into a user. Try to capture in safe mode. This will turn off any pesky programs you may have running in the background.
Make sure the drive you are capturing to has enough free space. If you are capturing to a drive that is close to full or heavily fragmented, it will slow the capture process down and drop frames.
Other than that... it could be a memory issue or it could be the speed of your hard drive.

Ran Software Updates and Now Drop Frames during Playback

I updated all of my Software back in late December. Since I have updated, all projects (old and new created ones) within Final Cut drop frames during playback. I had no issues with drop frames until I ran the Software Updates. Currently running Leopard 10.5.6, Final Cut 6.0.5, Quicktime 7.5.5. Any suggestions on how to determine why I now have drop frames. Is there an easy way to revert back to software that was in place prior to me running Software Updates on 12/22/08?
Thanks in advance for your comments and suggestions.
Jim Bob

ZRose:
First, you should have an up-to-date tested reliable backup. The best way to do it is to get an external Firewire HDD, clone you entire computer to is using SuperDuper, then keep it up-do-date.
Next, get in the habit of doing regular maintenance procedures. Here are some links to help.

Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.

Export Quicktime = stalling / frame rate / dropped frames

Firstly this issue isn't news. It appears it has existed since 2002 at least on these forums and Apple has done nothing.
Exporting to Quicktime:
1) Keynote makes up what seem to be consistent random frame rates on export
- Codec doesn't matter. Photo JPG, Intermediate, 8bit 422, H264
- You can set the frame rate in export / custom / settings it doesn't matter
- Having no video on a slide or having video on a slide doesn't change the problem...
- The last two items do have more information to complete their story
- If you do have a video on slide at say 25fps and export (at same rate) the random will stabilise
but it will stabilise to something bizarre, such as 23.69.
- So Keynote can wreck your frame rate it will drop frames, or even add frames while dropping
others. It is deeply sophisticated in how it destroys stuff on export.
Result
- is a stuttering output if embed video on a slide with a wrecked frame rate
- and a random frame rate if you don't have a video embed
2) The video stalls between slides
- Keynote seems to play a trick by making a single frame span multiple frames
- At the start of the first slide this seems to vary. The first frame can be between 7 and 33
frames depending on some strange internal logic only known to Keynote
- Between slides it will hold the last frame of the exiting slide usually for 7 frames and hold
the first frame of the entering slide for usually the same amount.
- No amount of change to settings such as transition delay, adding a transition, self play etc
will effect this stalling from what I can tell.
- You can analyse the reality of the issue by dropping the resulting file into Quicktime 7 and
changing the video window "time code" display to frames by clicking on it and single framing
through the video. I have Quicktime Pro for the record.
Notes:
- I have every update installed and am running 10.6.2
- I have tried it on two machines, one a clean build, server or client
- Playing the presentation direct in Keynote does not present any of the noted issues
- I have spent the better part of two weeks on the issue trying all sorts of combinations
- Video of different frames rates, sizes, codecs. All useless, don't bother.
Outcome:
- Keynote is completely useless unless you just want to play a presentation in it
- Dropped frames, stuttering video, stalling, mangled frame rates, fake frames
Solutions that aren't:
- One suggestion for video embeds is to enter a strange custom frame rate. For example a
24fps original turns into a 23.69 export, if you up the frame rate to 24.3 the resulting export
is 24fps.
This is a truly hit and miss affair and will require a lot of testing to nail it. Unfortunately I
tested the resulting video frame count in Quicktime against the original video and...
The amount of frames is not the same. Part of my assumption is that the stalled pad frames
are being considered by Keynote and it drops some frames to fake the same length, that at
least -seems- to be part of the result, but it doesn't account for all the lost frames.
- I have also tried just having one slide and exporting that. The same things happen regardless
How Al Gore managed to make "inconvenient truth" using Keynote is a complete mystery. Maybe on Tiger with some old version it used to work, yet from the forums it would appear it has never worked. This piece of software is a clear case of "it just doesn't work"
I hope you find this and stop hurting yourself trying to make this. I might hurt on a bit longer yet.

I can't answer in detail (I started with version 6, which I haven't used in years, so don't know what v5 did) but... a general comment
Software that old is very likely going to struggle trying to edit a VOB/MPG file copies from a DVD
If you are digitizing by playing the DVD through a conversion device you should end up with DV AVI which should edit well
Just what kind of files are you trying to edit?

How to overcome "dropped frame" issues on my project

Hey reader,
I have a MacBook Pro 2.4GHz with 250GB hd (85GB free just now) running 10.4.11, FCE HD 3.5 (and QT 7.5.5) and using a Sony Handycam DCR-HC96 (which is works BEAUTIFULLY with iMovie 08 and 6 and is always used with Sony tapes) and I am not able to "capture" the tape content to my MacBook Pro because of the "dropped frame" issue.
The camera is connected to the external hard drive chain via Firewire cable to the MacBook Pro and I was trying to capture to the internal hard drive. I am in the UK and am still struggling to get my head around the different frame rates but initially I got the dreaded "dropped frames were encountered during the last capture attempt" and it just wouldn't work, so I unselected the report dropped frames tab and abort capture in User Preferences as was suggested on here.
Now I get "Capture encountered a problem reading data on your source tape. This could be due to a problem with the tape. Capture has been aborted and your clip has been saved" but the tape is fine (heads are also clean) as I had to (under time pressure, me) use iMovieHD 6 instead and it worked like a CHARM.
What can I do to use this software?
I KNOW I can import the iMovie footage but the disadvantage is the eternal rendering, I guess. I only ever used it once (because of its difficulties) and that was for pre-existing footage from iMovie and it was OK if not perfect. Just had to have a few hours extra for the constant rendering in preview...
Should I try to capture to one of the external hard drives? I read that the internal might be a problem as it is busy with the operating system jobs.
Please and thank you.

I got some dropped frames last night and posted this before noticing your post:
There can be a number of reasons for getting dropped frames during capture.
Yesterday I videoed a relative's wedding (in HDV) and on getting home late I captured the footage into FCP 6.0.3 only to find in a couple of places I got an abort on dropped frames.
This morning I decided to recapture and did so without a single dropped frame.
Why ? ......... there are several possibilities.
It could be that there was some physical problem with the tape or camera heads but I believe it was most likely caused by my camera's power supply.
Last night I used the battery whilst this morning I plugged in the power connector.
I feel that this provided a more constant supply of full power and helped prevent frames from being dropped. (The fact I was using FCP is immaterial as the dropped frames would almost certainly have also occurred in FCE).
From now on I will always use the power connector during transfer to and from the camera.

Drop frames on external monitor

Hi, recently im having some troubles with cc 7.2.1, one of them is when i have cuda enabled i have droped frames on my external and program monitor, but the timeline is fast and i can edit, im editing a short documentary with 4 hours of footage in h264 from 5D an 7 D, on a usb 3 external. I have a macbook pro (late 2013) 16G ram , i 7, mavericks osx.
When i select software only i dont have drop frames on my external but i can't edit, because everything on the timeline lags. Image takes a long time to load on the program monitor and external monitor, impossible to do trim, takes ages for images with time code to apear.
When scrubing on the timeline, the CTI takes a lot of time to catch up. It seems like she is connected to a ruber band, it moves back before moving to my selected position!!
Do you guys think deleting cache and preferences will help? ( how can i delete them ?)
Thanks

Hi,
I was wondering if there had been any progress on this? I'm experiencing a similar problem myself with my MacBook Pro (Late 2013, i7, Nvidia 750M) in that I'm getting dropped frames when using an external monitor. My set up may be slightly different though but the results appear similar.
My timeline, program and source windows are all on the external monitor (Samsung SA850) connected via thunderbolt to mini display port. The playback monitor window is set to full screen on the MacBook pro and that is where the dropped frames occur. If I unselect using a playback monitor and just use the external Samsung as described, things appear fine.
I'm editing a mixture of H264 and ProRes clips on an hour long timeline with nested sequences.
Any advice on possible solutions or things to try in order to troubleshoot would be much appreciated.
Many Thanks.

Cc 7.2.1 lags on timeline and program monitor, and drop frames.

Hello guys i have cc 7.2.1, and every basic operation i do on the timeline , moving clips, trimiming, scrubing on the timeline everything lags, its not fluid. When i do a simple scrubring on the timeline, the CTI takes sometime to get to the position i selected to do the playback.
But the worst part is the trimming or moving clips, it takes ages before i get an image on the program monitor. If i move a clip into a middle of 2 clips it takes ages to see those two little privews images with timecode, to see where to put it. So is very hard to edit like this.
Another odd thing is when in redering mode i select to use sofware only i dont have drop frames, when i chose cuda i have drop frames!!
I´m editing h254 from a 5d and 7d on externa llaccie usb 3 , have the a macbookpro 16g i7, iris pro and nvidia 750m, and a external samsung, via DVI.
Anny sugestions?
thank you.

Thanks for the Tips.
One thing that i discoverd was, when software only is enabled i can't edit. Everything as that lag i reported above, but i have no drop frames with external monitor.
Now comes the funny part, when i enable CUDA for my Nvidia gt 750m, i can edit !!! everything becomes almost normal, image on program monitor comes quick, and i can do trims. BUT i have drop frames on external monitor!!!!! so therefore i cant have a proper edit enviroment.
The only solution is to edit without an external monitor with cuda enabled, that way i dont have drop frames. I guess this is a syntom, that something is not working well on CC 7.2.1.
Thank you all.

Dropping frames in QT export from CS3

I just got CS3 for my PC and I was all excited about the new
feature that lets you export dynamic/actionscripted/MovieClip
content. I do animation targetted at TV, so everything needs to be
rendered to AVI or Quicktime, so I figured that this new feature
would let me use a dynamic camera symbol as I've always wanted to.
I've run into a problem, though: the export process seems to
drop frames! As far as I can tell, Flash is rendering and recording
the frames of the animation in real time (or perhaps just close to
real time). If the computer has any hiccups because of another
process demanding some processor time then the resulting quicktime
will have frozen bits where the renderer couldn't keep up.
You can see what I'm talking about by looking at the
quicktime and an AVI of the same scene here:
http://www.pinkandaint.com/flasherror/bad.mov
http://www.pinkandaint.com/flasherror/good.avi
To test this theory, I tried witching applications a bunch
during a render. Sure enough, there were long sections in the
resulting quicktime where the renderer missed frames. The quicktime
is the right length and number of frames -- it just repeated the
same frame over and over where it couldn't keep up.
That's not the only problem, though. When I look at the
exported quicktime file in either Quicktime Player or Premiere pro
(version 1.5) it reports a framerate significantly lower than in
the original FLA. In the file I'm looking at right now, the FLA's
framerate is listed as 29.97 but the MOV file reports a rate of
19.29 (which is, incidentally, different than the framerate I got
any other time I exported the same scene). In premiere, when I tell
it to interpret the footage as having 29.97 fps the clip gets
significantly shorter than it should be -- in this case 161 frames
rather than the 208 frames that it is in the FLA.
I'm pretty sure this is the same way that the various
SWF-to-video programs do things. I thought it was an interesting
kludge to use those external programs but I was sure Adobe would be
able to do something more elegant and sure-footed with this new
export feature. Couldn't they have somehow guaranteed that each
frame would get captured? It seems like they could have just
modified the Flash player to play with artificial time, where the
time to render each frame was always reported as 1/framerate.
Oh, and there's one more problem. The Quicktime renderer
seems to do something different about the order of execution of
actionscript or something. In the rendered quicktime movie the
first frame displays my camera symbol even though I explicitly made
it invisible with actionscript on the first frame of its timeline.
When displaying in the Flash player the first frame does _not_
display the camera symbol....
Has anyone else encountered these problems? If so, have you
figured out a workaround? I tried setting the framerate really low
(I was at 29.97, so I set it down to 10) but it still seemed to
miss frames.
-David

I can understand your frustration with this feature as it
tries to capture in real time what's being
compiled in the player - but your last line is a bit unfair:
"...it
> exemplifies the Flash team's disregard for animators in
favor of web developers."
Copy Motion and Copy Motion as AS3 are useful new additions
for animators. I will add however that I
myself have a list of animation oriented features I would
love to see added in flash but for now
have you checked out www.flashants.com and their SWF2Video
tool? It exports an SWF to AVI with
flawless results. Worth looking into if you have the need to
output any kind of flash content to video.

Dropped frames on capture

FCP 4.5
last week all workflow was fine.
yesterday (saturday) I could NOT even capture 1 minute of DV video without aborting after 20 seconds due to dropped frames. I wiped a drive clean thinking too much fragmentation. The only thing that changed is I updated OS from 10.4.8 to 10.4.9 when it came out. I could however capture my DV using iMovie, export it, and work as normal in FCP. I hope FCP v6 comes out soon like at NAB next month and I get back to normalcy.

What I really want to do is go back to the previous version of Quicktime I was using (7.13) -- and I can't. I have deleted everything even resembling Quicktime from my system, as well as all the .plist files and prefs, and yet the 7.13 installer will not install; it says that I have a newer version (7.15) installed. Where else does Apple hide Quicktime prefs information?
Re-installing 7.15 did NOT solve the problem. Here are some more details:
When capturing from Final Cut Pro and iMovie, I get 50 or 51-frame gaps. Audio continues to be captured, only the video cuts out. Each gap seems to be 40 to 60 seconds apart. These gaps are actual holes in the data. Cinema Tools diagnoses the clips as damaged.
I removed the camera from the equation by using a different camera for capture.
I removed the media from the equation by using another DV cassette that I recorded recently and was able to capture from (last week) with 100% success.
I don't think QT is a factor either, because I deleted and removed all QT software and rebooted, and FCP still runs and still has the problem. I don't think QT is used unless you actually export from FCP.

Ability to Recover Dropped Frames in Spanned MTS Files?

Hi everyone,
I know there's a previous thread about an issue similar to this, but it's been a long time since someone commented so I'm trying to get a quicker more specific answer here. I'll keep this short:
Using a Sony NXCAM, and I was not aware of needing to use the Content Mangement Utility to export footage onto my editing machine. I realize this is how you get the spanned MTS files back into a single file. I now have over 200 GB of footage shot over a week long period. I just copied over the MTS files ONLY to my editing machine each day, then reformatted the cards to make space for the next day's footage.
Now, when placed in the timeline, all the clips have the dropped audio frames where they were split.
My question is, is there a way to recover/recombine these files AFTER they've been taken off the memory card, and I no longer have anything but the MTS files only - not the PRIVATE folder, or any of the accompanying stuff.
Am I SOL here? Or is there a way to recombine the spanned files at this point?
Using Premiere Pro CS5.5, but also have access to CS6 if needed.

I was not aware of needing to use the Content Mangement Utility to export footage onto my editing machine.
You don't. In fact, I always recommend no special software is used. Just Windows Explorer or Finder. BUT...you do copy over the ENTIRE CARD. Once on the hard drive, you do not delete, rename or otherwise alter the contents of any of those folders.
The dropped frames you're seeing are common when you do not copy over the entire card. I am not aware of a fix.

Premiere Pro 1.5 - dropped frame issue

First let me say I know this program is out dated so let's not get into that. (or maybe we will) The company I work for is small and just can't afford to upgrade. So, as I am stuck with this program there have been reoccuring issues with dropped frames.
I use a PD-150 and/or DVX-100 to shoot. I used a mini-DV deck to capture to the system via firewire. I noticed that there were several random dropped frames throughout the show. (The show being a dance recital) The big hassle is that it is a two camera show and so everytime I think I have the cameras matched up, oh gee great, there's a nother dropped frame. I then recaptured the tapes from the camera that they were shot in. Same problem, only the dropped frames were in different areas. Does this mean that the tape is not damaged? That it did not occur during filming? Is it a problem with the capturing device? We have a Matrox system. I am also capturing to an external harddrive. Firewire. But this has happened when I've used the computer hard drives for project space. So, I'm not sure if that would make a diffrence.
Basically, wtf can I do to stop dropped frames?
Is it the video card? capturing system?
Do we really just need to upgrade our software to solve the issue?
If indeed there is a solution, would I have to recapture everything in order to get rid of the dropped frames?
Help please! Thanks!
Kip

Recapture to a internal drive is your best option imo.

Dropping frames on my software only
