Dropped frames - jumpy playback

I just moved an old FCP3 project to an external drive and opened the project in FCP5. I'm getting dropped frames and generally jumpy playback in the canvas. This may have nothing to do with FCP3 > FCP5 conversion- just thought I'd mention it. Perhaps just a simple oversight in one of my settings. Any ideas would be extremely helpful.

#12 Dropped frames on capture/playback
Shane's Stock Answer #12:
http://docs.info.apple.com/article.html?artnum=58640
1) Do not capture to your main system drive. Since it is busy reading the operating system and application files, it will intermittently drop frames during capture.
2) Do not under any circumstances run any anti-virus/filesaver software. Including Norton and Virex. Sure, Apple doles out Virex for free, but FCP doesn't cooperate with it very well.
If you absolutely feel you must keep Virex installed on your system then use Kevin's script to shut it off before you use FCP:

3) Check the format of the drive you are capturing to. It should be Mas OS Extended, jornalling off. If it isn't, copy your files from it and re-initialize it. If it is any other format, you will encounter problems. If not at first, then eventually.
4) Trash the FCP preference files. Use FCP Rescue available here:

"Dropped Frames on Playback" - when playing back FCP's Bars+tone

We've been having a problems with one of our edit suites dropping frames when playing back to tape (Edit to tape).
In checking it out, I created a new project and added DCP's PAL Bars and tone to the default sequence. FCP is stopping playback with the "Dropped Frames on Playback" error after 13"-15". I've tried all the usual stuff - trashing FCP prefs, zapping PRAM, repairing preferences etc.
Has anyone any further suggestions??
RT is set to Safe, with dynamic frame rate and video quality.
The Mac is a Dual 2.66GHz Dual Core Xeon, 4Gb RAM, with an AJA kona lhe card, connected to an XServe Raid via fibre. The tape deck is a DigiBeta M2000.
I've read all the posts I could find, and checked Shane's stock answer #12.
Cheers

Try creating a new user, log into that and test FCP.
In my case, a new user worked, for awhile.
Through a lot of trial and error and a reinstallation that was ineffectual - properly surmised by a very learned friend of mine, Mr. Sheffield - I found a project to be corrupt. So thoroughly corrupt that it would corrupt FCP and any projects opened downstream which is why my new user worked for awhile. Took me some time to figure out the proper order to open things after a system restart. Looks like I'll be doing a rebuild of the project through xml which shouldn't take to long.
In your case, if a new user doesn't help and you go the reinstallation route, uninstall FC Studio with this jewel of a utility. Many thanks to Jon for writing and distributing. http://www.digitalrebellion.com/blog/posts/fcsremover_1.0.6released.html

Dropped frames on playback doesn't replicate in a new user account

I have been using FCP 4.5 for some time without any problems. Recently I have not been able to play clips in the Timeline without an immediate error message of dropped frames during playback. If I double-click the clip it will play in the Viewer perfectly. This will happen even if the only sequence open contains a single audio track.
I tried the same thing in a new user account and everything worked as it should, so the problem appears to be a conflict confined to my original account. I've tried moving prefs files for FCP and Quicktime but no joy. All source material is on a separate internal drive to the OS & project files.
Any ideas?

It seems that I did not remove all the necessary prefs files - I have done so now and all is well, thanks to Ken Stone. He has a thorough description of exactly what to trash here:

Troubleshooting dropped frames on playback FCP 5, Tiger G5

for some reason i keep getting dropped frames on playback after upgrading everything to tiger and fcp 5...
i'm working off of a lacie d2 firewire 800 drive on a dual 2.0 G5 with 2.5 GB of RAM..
even when i change the playback settings to dynamic or even medium and half resolution ... i still get dropped frames during effects like variable time.
has anybody else had this problem? perhaps i'm missing some optimization i should have done in tiger??
any suggestions?
thanks.

thought i'd post some of what i found out...
1) turning off my airport card has seemed to help a bit
-perhaps because dashbord is always running in the background (is there a way to disable this?)
2) turning off adobe version cue also seemed to help

Final Cut Pro dropping Frames on playback

I am editing a multi cam video in final Cut Pro. I have set playback to proxy media. I have 250gb free hard drive and 8gb ram. I have an IMac that isnt a year old yet.
I have previously completed a music video, excactly the same composition of 3 camera angles and a soundtrack and no issues at all.
The individual clips play fine but when I play the multicam clip its dropping frames on playback and output. The video is lagging behind the audio.
Considering upgrading ram, but Im confused as to why last week I could do this perfectly and now the machine seems to be struggling?
Any suggestions greatly appreciated!

1) IF the clips are playing back fine without the effect. It is NOT the drive speed causing the drama... The effect is.
2) FCPx is NOT a real time application like PPRO when effects are applied. Sometimes if your GPU is strong enough and if the effect has been properly coded you WILL be able to achieve real-time performance... But in most cases not...
3) FCPx has BIG problems playing back video in real-time as it is. Even if its ProRes and residing on a super fast SSD... FCPx HAS problems which are hopefully being worked out as I write...
Solution to your problem is to render the timeline if you have effects on any clips. Also, make sure that your project is NOT residing on the same disk as the event library which it is using. The project ALSO need to be on a fast disk because ONCE you render the timeline, the video is being played back from a file in your project folder and NO LONGER the event library
Hope this helps

Dropped Frames During Playback

So I'm new to Final Cut Studio and have been trying to ingest footage from a SANYO digital file based camcorder. It records in several HD modes including full 1080i and in MPEG-4 file form. I've had trouble getting the files into Final Cut on my MacBook Pro and editing without constantly having frames dropped. I'm not sure what to do. Is it a problem with my computer (which is brand-spanking new)? Also, I get a warning when trying to Log and Transfer the footage telling me I have un-supported media. Any insight I can get on the issue would be excellent.

FCP works best when the media you're importing or capturing matches the Sequence settings. Check your Sequence settings in FCP and see if they exactly match the settings of the clips you're trying to use. If they don't match, it may be best to convert them to match PRIOR to importing them, or use Sequence settings that match the clips.
FWIW, when you get dropped frames during playback, it's an indication that the effort to read and display the clips is exceeding the ability of your system. This can be due to a number of things or a combination of things. Some of the conditions that can contribute to the problem are (in no particular order):
• data throughput problems due to hard drive connection, buss speed or drive speed
• using media made with a codec that isn't fully supported in FCP
• using corrupted media files
• RT settings not right for your system
There are other conditions as well, but those are the most common.

Dropped frames during playback & must render everything & tried everything

This is an updated question. My last posting for some reason did not include everything, such as my System Settings, A/V Settings, and View Settings. There also was no Preview option. Hope it works this time.
I am editing a multiple camera project with a lot of color correction (to get the cameras to match up), and photo montages with motion and image compositing.
I am getting way too many dropped frames during playback, and I have to render every little thing, even simple dissolves. It's taking forever to work like this, and is extremely counter productive. I have tried all the obvious things, but nothing seems to be working. Please help.

Even if you use Dynamic as your playback setting, depending on the complexity of the edit or composite, you may still get dropped frames. Keep in mind that the weak link in this chain is the FW800 connection. You also mentioned that you using quite a bit of color correction as well as motion effects. Depending on the color correction, the more that you add to your sequence as far as effects are concerned, the more processing is required. The dropped frames that you are experiencing is most likely the computer trying to maintain realtime playback at the expense of the quality of the picture. In order to really judge the final result, you'll need to render.
The official definition of Dynamic Playback:
This option allows Final Cut Pro to automatically change between high,
medium, and low quality as necessary to maintain real-time playback. In this case,
the quality of the video resolution can change frame by frame.

Dropped frames during playback due to "slow disk"

I work off an external Rocstor 160gb firewire drive; suddenly as I started to edit a project I get constant dropped frames during playback. It says it's due to "slow disks" and I wondered if my hard drive was dying. But I opened other projects on the drive and they play just fine. Why just this one? It's shot on the same format, captured the same -- nothing's different from my older projects. Maybe the captured media files got corrupted? I've never seen this. I've tried using the Rocstor on three different machines (first a 17" PB, then two different G5 towers) and it happens on all of them. I have FC5 on the PB, but FC6 on the G5s -- doesn't matter. I'm stumped here.

How full's the drive? The fuller it gets, the slower it becomes. If it wasn't a superfast FW drive to begin with (especially a 400 device) You're gonna have problems as it gets fuller... starts slowing down big time around 70% capacity. It's always something... if the drive's not in a fast enclosure, and is also a fastish drive has a least 8mb disk cache, it will behave like this with DV footage.
One thing I've seen and learned from reading a few posts on this is that the better/faster stuff suited for FCP use is worth the investment. G-Raid, Grainite Digital, OWC all sell really nice FW800 setups... they are up to twice as fast as older/slower FW 400 drives. and NEVER buy any more than you need now for storage. It's half the price and twice the speed next time you need more it seems.
eSATA should be considered by any pro. laptop or not.

Dropping Frames on playback on brand new Mac

Ok, I just this week recieved my new MacBook Pro, and I have a problem that i think I know the issue but I just need some simple confirmation from the pros. I Am experiencing dropped frames on playback no matter what settings i change So I am going to assume that I need a faster Harddrive than USB 2.0 (500 Gigs 65-70% capacity). Am i Correct? should i spend the money on a Firewire 800, will that make the dropped frame problems stop, because all I am doing is changing a clips speed and it continues to drop frames aqnd barely play. Thank You all in advance

The cards are made by several manufacturers, and i don't think there's much difference between one and the next except for the number of ports it adds.
http://www.weibetech.com sells external SATA drives and arrays, and if you go with an array, I'd look at http://www.caldigit.com for those...
http://www.g-technology.com also sells some external SATA drive setups.
firmtek also sells a dandy, it's reviewed here: http://www.barefeats.com/hard71.html
You'll need the express 34 card adapter, and they are sold by cal digit, and others like: http://www.sonnettech.com/product/temposataexpress34.html
That should get you started...

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.
Macintosh OS X Routine Maintenance

For the probably immediately at hand
Repair Disk
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.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
BGreg's suggestion to install the Combo update is a valid fix. Remember to Repair Disk Permissions before and after installation.

Dropped frames during playback in FCP 7

I have searched high and low, asked every FCP expert I know, and noone can help me.
So I turn to this forum and you the users for help.
I just upgraded from an old DVCAM to a new Canon 60D, which shoots full HD. Usually I never have problems editing with or without text, but all of a sudden I got dropped frames when I put text on my project. No warning of dropped frames though. Just some skipping and pausing before the clip continued.
I was running FCP 6 but upgraded to FCP 7 in hopes of it removing the problem. It just got worse. Now I can't even playback video or text by itself (I am testing with 5-10 second bits). Whenever the screen should go blank I instead get the unpleasant warning of dropped frames. The same thing happens when I play text by itself or over the video. When I try exporting it (to see if it is just a playback error) QT and VLC Player both show the most hideous grey, green and pixellated versions of my (still very short) clip.
And if anyone suggests changing RT options - where do I find those options? The RT button on my timeline only shows the options: "play base layer only", "use playback settings" and "Full quality" - and the problems keep showing up in all three selections.
Could my settings be off? I am not sure I have found the right ones for the footy from a Canon 60D.
I hope someone is able to help me with this. It is the most frustrating experience I have ever had through my many years with FCP.

Switching from DV to HD can be a nightmare if you were 'getting away with things' using DV material that you really won't be able to in HD.
First - Where is the media? If it is on the system drive of the macbook pro... get it off of there!! It should be on an external drive - FW800 will get you going better than anything else...
Second - simple fix, but make sure... are any of your windows overlapping? is your canvas window set to FIT TO WINDOW? If there are scroll bars in your canvas or viewer that would be bad too.
Third -- let's figure out what and how you are converting the material off the 60D.
What is the workflow you are using? You should probably be editing in some form of Apple ProRes... I like the LT setting - minimal quality loss with max gain in bit rates.

Dropped Frames During Playback, How Much Hardware Should I have

I have a Mac Pro Dual Xeon 2.66 with 1 gig of ram and the Nvidia 256 meg card, I added a second hard drive which is a Seagate Barracuda 320GB 7200 RPM SATA 3.0Gb/s and that is my scratch disk. I was trying to play a sequence that is from the tutorial disk in the Final Cut Pro 5 book by Diana Weynard. For those who know the book it is the "adding text" sequence from lesson 15.
I can play most of the sequences on the book's dvd in real time fine except for this one. With this one as soon as I get to the clips that have a lot of audio channels as well as a lower third text effect I get the dropped frames message. I can render the whole sequence and watch the whole thing fine. Really my question is this: I thought having spent what I did on a mac pro that would be enough hardware power to play back almost anything in real time, but do I need something else like more memory or the faster ati video card to play back this "heavier" sequences?
I've tried various solutions like deleting my pref file, reducing the number of real time audio mixing tracks to just 2. I even deleted the audio tracks in teh sequence so there were only 2 video tracks that had to play - a person speaking with just one outline video effect on the track above, and still it drops frames.
Thanks.

Some of those sequences are HD. A single 7200 rpm drive will only deliver one or two HD streams without choking. My 7200 rpm internals will only deliver 4 streams of DV before skipping. If I move some clips to another drive and segregate my render files to another drive I can get up to 6 DV streams but it's not reliable.
Processing the audio requires significant overhead as does recovering the audio segments of the files. I rarely have more than 6 tracks open.Lowering the playback quality will increase the numbers of tracks you can play in realtime.
History note: Older NLEs required audio and video to be captured to separate drives, unnecessary with DV.

Dropped frames during playback from timeline...help asap!

I'm running Final Cut Express 4.0.1 (I've checked and installed latest updates) on a 24" Intel iMac (2.66 GHz Intel Core 2 Duo, 4GB ram) which I purchased on August 2009.
Before I purchased my new iMac I would use FCE on my 15" MacBook Pro (purchased April '08, similar specs to my iMac) and it would work just fine.
Now here's the problem with running it on the iMac...Everytime I playback any video from the timeline, it would immediately drop frames in less than 3 seconds (even without any effects or filters) and reveal an error window:
"One or more frames were dropped during playback
If this occurs frequently, try:
-Turning off Unlimited RT
-Lowering your compression data rate
-etc..."
However the video in the "Viewer" window plays back videos just fine. I've tried changing scratch disks from an external drive to the internal HDD (both of which are more than 70% free) to no avail. I used to always use Unlimited RT without a problem when I used FCE on my MacBookPro with an external drive. Am I missing a setting that I used with my MacBookPro? I've even opened FCE projects I made using my MBP, and the iMac drops the frames when I play them back.

Here are some screen caps of the item info windows:

http://img43.imageshack.us/img43/1696/screenshot20100608at115.png
I'm using an external HD, an Iomega 1.5TB - Mac OS Extended (Journaled). However it's USB and not firewire (which again wasn't an issue with my MBP). I've also switched to the iMac hard drive and the problem persists.
Let me know of any other info you'd like me to pull up for you.

Dropped frames during playback. Dumb question but I'm just starting to edit again with a new comp. and FC 7

Hello out there,
It's been three years since I've used Final Cut Pro and I"m just getting back in to it. I'm working on my first project editing footage from my Canon 5D markII.
I'm trying to do a simple cross fade on the video track but when I watch the playback I'm getting a dropped frame message. I am using the highest video quality on my cannon but it seems like my computer with a 3.4 Ghz prossesor and 32 gigs of ram should be able to handle a simple cross fade.
Could it be that I need to change a setting somewhere to make FCP handle my canon's video better?
Thank you so much!
I appreciate the help.
Mike

Please tell me you converted this footage...the native H.264 format the camera shoots...to ProRes. Because FCP doesn't work with H.264 well at all.
I have a workflow for this and other tapeless cameras here:
