Dropped Frame Errors When Time Remapping DVCPRO HD 720p60 Clips

Wondering if this is common due to FW800 throughput limitations or abnormal behavior.
I'm editing several DVCPROHD 720p60 projects and cutting them in FCStudio is like butter on a Dual 2 G5 connected to a FW800 G-Raid. I needed to time remap a clip and lo and behold, some dropped frame errors. Recreated and retimed several times with the same error. Dropping down the playback quality fixes this but wondering if it would be a normal occurance to see this with DVCPRO HD footage.
Any thoughts?
Dual 2 G5, 17 & 15 PB Mac OS X (10.4.7) Monitors, G-Raids, and Cameras, oh my!

It may be normal... a lot depends on which machine you're using, but If it drops frames, render it...

"Dropped Frames" error when capturing to Drobo external drive

Hi, I am looking to buy another external hard drive for video editing with Final Cut (as my scratch disk). I had purchased a Drobo because of the data redundancy and ease of use, but it's definitely NOT an editing drive - way too slow, I can't even capture video to it without getting "dropped frames" errors (even w/Firewire 800). And after searching these forums, I've read that others have experienced the same problems and that in the end it turns out that the Drobo is not an editing drive. Jeez, that was an expensive learning experience.
Soooooo I'm not very knowledgeable on hard drives, RAID, etc... but I would like to buy something that has redundancy (would that be RAID??) but is absolutely HAS to be something I can capture video and edit on. I know some people have bought 2 drives, one for editing and one for backup, but I know I'd forget to back it up every time and it seems like a bit of a hassle. Just thinking there's got to be an easier way that's hopefully not too expensive.
Are there any editors here who can point me to specific hard drive models or tell me exactly what I need to look for in a drive? I believe OWC (http://eshop.macsales.com/) probably has what I need, I just don't know what it is I need to get since I'm hard drive ********. Any advise would be appreciated!

Thank you Shane. Wow, didn't realize how expensive that would be. Not an option for me at the moment then.
That said, is there another hard drive (non-RAID) that is good for editing? For instance, could I use a Western Digital MyBook (http://www.amazon.com/exec/obidos/tg/detail/-/B000VZCEU8/ref=ordcartshr?%5Fencoding=UTF8&m=ATVPDKIKX0DER&v=glance) to do my editing and then have another one for backup? Sorry for all the questions, I just want to make sure I understand and get this right!
Thanks

Having drop frame error messages when in playback mode?any feed back on what i might do , Idont have a serial number and Im currently not upgraded ththe 10.03 i am in 10.00?

I am getting drop frame error messages when in playback mode (final cut pro 10)? Any feed back on what i might do , I dont have a serial number and Im currently not upgraded to the 10.03 I am in 10.00. I inherited the finalcut pro from my old computer and now have the IMac 27! ant suggestion other than upgrade!

If you have FCPX (10) you can upgrade for free at the MacApp Store.
Did you click "proxy media" when importing? That will help playback.

How to sync/edit audio when using frame freeze or time remapping?

how to sync/edit audio when using frame freeze or time remapping? in premiere pro cs6

You need to give more information about what you want to happen to the audio when you freeze or time remap the associated video.
Is it synch video?
Is it music?
Is it Voice?
Generally .. you have to cut and design the audio around the video effect.

Why am I suddenly getting a "Dropped Frames" error?

Hi,
For two years I was working on a large project in FCP 6 where I was able to do quite a bit of work without ever getting "dropped frames." Recently I deleted this entire project and loaded footage for a MUCH smaller project. This current project is MUCH less demanding. Fewer effects, fewer timelines to work with. Same exact system. Nothing has changed... except now... the mos rudimentary effects will give me dropped-frames upon playback. I know I can toggle a playback settings but how in the world is this suddenly necessary with a project that is 5% as demanding as my previous project??
In particular, the dropped-frames occur when I'm...
* generating basic text and adding a fade to the text
* cropping part of one shot
The specs are the following:
+ MacPro 2.8gb 8-core, 16gb RAM, Mac OS X 10.5.4, four internal hard drives at 500gb each
+ My OS and the FCP program are on Drive 1
+ My audio is on Drive 2
+ My visuals are on Drive 3
+ My FCP file and the render files are on Drive 4
+ The project itself is using footage from a Sony EX1 camera. I'm using audio from AIFF files. The progrmam is 2 minutes in duration. I'm using very little effects at all. 1 track of video. Four tracks of audio.
What's going? Why am I now, with this new/smaller project, suddenly getting dropped frames? Was the deletion process the culprit? What can I do?
Thanks,
Shanked

Download and run the demo version of iDefrag : http://www.coriolis-systems.com/iDefrag.php
Click the drive in question wait for it to build the map then switch to the tab labelled "Files" at the bottom of the window. Sort by #Fragments and the highest will be likely culprits. If you do buy this software change the algorithm to "Optimize" for best results for video. Run it using default settings for the rest of it.
For anyone else reading this I DO NOT recommend using defrag tools on the system drive or a RAID drive. This WILL make things worse for you. Only for use on single drive scenarios. The best way to defrag a RAID array is to move the files off to another drive, wipe the RAID clean then transfer the files back again (You can do this for any file system to improve performance). This will sort the files out again. OSX manages the rest until there is only 10% of your drive left (depending on how much deleting and writing of files happens in between - it's that which cause fragmentation).
In terms of the 'size' issue (which you have no real issue with) I guessed that you meant the duration and complexity of your sequences. It's true that sometimes if you have a lot of sequences open these will use up valuable RAM (as FCP is only 32bit it can only utilize 3GB of RAM at most) and so when it is trying to buffer, cache and output the video it can trip over itself. But your current problem is definitely down to dataflow off the drive and into FCP in time to decode and display the next frame. If it can't do it in time (within 0.03-0.04 seconds) then if detects an error and because you are in SafeRT mode it stops playback and displays the Dropped Frame error window.

I am getting this error when time machine tries to back up to a time capsule. "The backup disk image "/Volumes/JUDY ARCENEAUX's Time Capsu-1/JUDY ARCENEAUX's MacBook Air.sparsebundle" is already in use." Same time capsule has worked in the past.

First, restart the computer and the Time Capsule. In most of the cases, this should solve the problem.

Repeated frames when time remapping AVCHD clips in AE

I will try to explain the best I can. Keep in mind I am a novice and by no means highly technical. First some background: I edit sports video for college bound athletes. I put together highlight videos for them. When I am filming I start/stop the camera at the beginning/end of a play so I can easily identify/edit "clips". I have imported 10 AVCHD "clips" from my Sony HDR-SR11 to a Premiere Pro CS4 project. I am using the "AVCHD 1080i anamorphic/29.97fps" sequence setting as my output for this project will be a 1440x1080 mepeg2 file. So I get my clips in the timeline add some transitions, no major edits, render the work area and playback. Everything looks fine, all clips play smooth. Now here's the rub. I want to freeze play, highlight an athlete then continue play. To do this I am using AFTER EFFECTS (NOTE I have done this with HDV footage off my Canon HV20 camera with no problems) so anyway with the new CS4 edition I can right click on a clip in my timeline and choose "replace with after effects composition"....I do and the clip migrates to AE into a a composition ready for me to work my magic. So my method for freezing play is select the "clip" in the composition, Ctrl-Alt-T for time remapping. I add 5 seconds to the duration of the composition since I am going to add time when I freeze the clip. I find the point in the clip where I want to freeze it. I place a "time remap" keyframe at that point. I then drag my mouse to highlight the keyframe I just placed and the keyframe at the end of the clip......I drag them to the right 2 seconds, then cut/paste the keyframe I added which is placed by the CTI (which is still at the original point). Now I have a 2 second freeze in play. I add a white solid and do some masking to highlight the athlete during that freeze. And that's it.....I press "O" then "N" to define the work area then I choose "trim comp to work area" from the composition menu. I repeat this process to all my clips and here is where I see the problem. I go back to my timeline in PP and I play the clips......I see my freeze/highlight edits from AE just fine but on SOME clips......2 out of 5 for example.....I get jittery playback. So I decided to scrub thru the clip frame by frame to see what is going on. So within 29 frames this is what I see. Girl is getting ready to serve a volleyball....Frame 1-15....she steps forward to serve THEN at frame 18 she pops back to the starting point...IT LOOKS LIKE FRAMES 1-12 ARE BEING REPEATED. I scrub the rest of the clip and this happens at random points....a small block of frames gets repeated throughout the clip which in the end looks like "jitter" or "jumpy" motion. I follow the same workflow in AE for each clip BUT this "jitter" does not happen on every clip...only some. So is my workflow at fault or is AE/PP/Adobe still buggy when it comes to working with AVCHD codec?? Anyone else experience this, if so do you have a fix?

I haven't tested your theory yet Andrew but I did do this. In trying to track down exactly where these repeated frames are occurring. In AE I redid one clip that was repeating frames. I went frame by frame in AE and see no repeated frames. These changes should occur automatically in PP since the AE comp is still dynamically linked to my PP timeline. So I scrubbed the "source" (AE comp) file from the PP project panel frame by frame. And low and behold there are repeated frames, so it appears the problem is the handoff from AE to PP Sooooooo, ok I deleted the source file in the PP project panel and reimport it via dynamic link. Open the clip in the source monitor and yes...repeated frames at same point....recheck the comp in AE....no repeated frames. Delete the clip from PP project panel and this time import the clip directly instead of dynamic link.....repeated frames still there. So how about rendering the clip in AE the old fashion way then import to PP. AE Render Queue best settings - lossless.....blah blah blah. I ended up with an .avi file with no repeated frames. So to me the problem is the handoff between AE & PP. So rendering my AVCHD comps in AE first is my work around for now. Andrew...thanks! I will try your theory of converting the clip prior to the comp asap...right now I am trying to meet a deadline.

Playback dropped frames - worst when re-starting computer

I'm editing a short 3 minute project - DV-NTSC sequence - and am getting those **** occasional dropped frames during playback (not in the same place) and cannot figure it out for the life of me.
I'm new to editing and am using FCE HD 3.5
New mbp 15" 2.16, 2 Gig Ram, 160 hard drive
10.4.9
Seagate 400gb ext. drive (325gb free, FW800, Mac OS Extended, journaling off) built by OWC (Mercury Elite Pro al) w/ media, waveforms, thumbnails, etc
Settings: Safe RT, Dynamic video quality, Full frame rate, Real-time Audio Mixing to 4 tracks - low quality playback.
Canvas/viewer etc are not overlapping. Am viewing at "fit to window" size
Easy setup - DV NTSC - and all my media is DV/DVCPro - NTSC, with 48khz, 16-bit audio. Some files are anamorphic and I've changed distort and motion to make them fit 4:3.
Activity monitor shows FCE using 20-36% of CPU during playback.
Energy Saver set to Never sleep computer, Never sleep display, don't sleep hard disks, no screensaver - and am running Spindownfix. Universal Access is off. Firevault not enabled. No other programs are running
I am new to editing so please let me know if doing this could be the culprit: in some places have 3 tracks of video overlapping - not because i need to but out of laziness; in others have 3 overlapping video with a lot of keyframes adjusting opacity. ALSO: Am setting Au dynamics processor for lots of the audio - and also changing the level db in the stereo track for the same audio - should I be making these changes in the au dynamics filter instead?
Also, problem seems to be worse when I first re-start the computer - and tends to get better as I go along....?? (I assume its okay to restart my mbp without unmounting my external drive? - that it does that automatically?)
I am rendering everything (although isn't it supposed to play without dropping frames without doing so?) At one point, my project wouldn't let me render portions of audio (they were marked red, but nothing would happen when I tried render all audio or mix down etc). I trashed my preferences and that seemed to fix that problem.
I feel like I've tried everything. I'd really appreciate any advice. (Since the problem isn't all that frequent, should I consider just taking off the "report dropped frames" warning until I'm closer to a final cut?) This is a new machine, so if its a hardware problem i definitely want to get it fixed sooner than later. Thanks!

The first thing I'd try is to mixdown audio (alt-cmd-R), and see what happens.
In addition I wouldn't leave overlapping clips unused in the tracks, even though I'm not sure it makes much difference.

Drop-frame to non drop-frame error

I just upgraded to Final Cut Studio 2, FCP 5.0.1 and I get this error message with every single tape I try to capture: "you are about to capture Non-Drop Frame media from a device currently detecting Drop Frame media." So, I click OK and capture anyway. The media is captured and looks fine - no audio sync problems. Then in the middle of my batch, before the second clip, I get the following error message: a change in time code rate was detected during capture of clip." I click OK and it captures fine anyway. Then later I get the audio sample rate error message too - it says: "The audio sample rate on one or more of your captured files does not match the sample rate on your source tape." But I capture anyway and everything looks and sounds fine.
I tried changing decks. Same problem. I checked the tapes and they were recorded as droop-frame and at 48 KHz 16 bits, same setting I'm using (DV NTSC drop frame 48 KHz)
Does anyone know if this is a Final cut bug or a real problem I should be concerned about?

It's neither... if you used consumer gear to shoot with, you'll get errors like this because consumer formats such as HDV, and DV are plain not that precise, but normally, you can just ignore them. As long as you're set up to capture DV at 48k and you shot DV at 48k, normally there's no problems even if these error messages are recorded.

Drop frame errors?

I'm using Final Cut Pro 6.0.2. When I bring up the log and capture window it controls whatever device or tape format I'm using (mini DV or DVC Pro). When I set in and out points the counter shows the time code info and it agrees with what the VTR is showing. When I click on Clip and say OK it tells me that it's having "trouble reading the data on my tape source." I have tried four different tape devices. I have tried to capture on the fly and I get a similar messages. I can Log and Transfer from my P2 cards without any trouble. Is there a drop frame setting that could cause this and where would I find the setting.

Thanks, but no I've tried several tapes both Mini DV and DVC pro that were recorded on the same VTR. I think this only began when we updated Final Cut 6 as I've been using my P2 cards for editing and I have no issue with them. Some setting some where but I don't have the experience to know where to begin.

DROPPED FRAMES ERROR

After converting my footage from H.264 to Apple Pro Res 422 LT, and getting a brand new super-charged iMac, my footage is still experiencing dropped frames every 5-6 seconds. The error message tells me to turn off UNLIMITED RT and even after doing that, I am still getting the same errors. I know it cannot be the computer, especially having got the new iMac with 16GB of RAM and a 2TB hard drive. ** All the footage is on the internal hard drive and not on an external. Does anyone have any ideas? I'm almost ready to ditch FCP and start re-editing in iMovie tonight.
Thank you in advance.
Stan

It was previously on an LACIE Firewire 800 External Drive and I was advised to move the footage to my internal HD for better playback. Perhaps the problem is not the drive, since I now have a 2TB internal ..... maybe the problem is the format it is in. I converted the footage to APPLE PRO RES 422 LT, imported into FCP and when I was editing it on my previous iMac, I did not experience the dropped frames as much. After getting my new iMac, the problem resurfaced .... which made no sense to me since I got a mush faster + beefed up iMac.

Dropped Frames, Error Messages - should I be worried?

Hi,
I recently upgraded to FCP 6 and I'm getting error messages when playing back video from my timeline saying there are DROPPED FRAMES. Sometimes it comes up with RED lettering and I get worried -- like my system is gonna crash or something. Should I be worried?
-JD

Is the firewire drive the only device on your firewire port and are you using the built in firewire port of the Mac, or are you using an internal firewire card you installed.
When you use a firewire drive to capture/playback from and are using the built in firewire ports of the Mac, (both ports share the same I/O) you can end up with dropped frames, if you are running a secondary firewire device on the same port, (such as a DV camcorder, deck, etc.)
This is why most FCP users purchase an internal firewire card to run the secondary devices from.
ALSO: Try tossing your FCP preferences, they sometimes can cause problems like this. You'll have to reset your preference after doing so.

Drop frames in Quick Time

In FCPx I exported a 4min video with stats: 1920x822, 30fps, mp4
And when I open it in quick time (X and 7) I've got drop frames during the playback. When I open whis video in VLC everythig is ok, very smooth video.
What the problem?
I've got iMac mid2011, 10.9.1 2,5GHz core i5, 12gb ram radeon 6750M 512 Mb.

What the problem?
Basically, the QT Players are, in some respects, less efficient than the VLC Player as many users have frequenty complained. Unfortunately, this is normal. QT players are, by default, programmed to drop frames if they cannot keep up with the "full" rendering of data at the encoded throughput data rate while other players may lower rendering quality, drop fields, or drop alternate lines in the rendering of progressive frames to "keep up." Such strategies allow multimedia players to work on a very wide range of platforms with varied CPU clocking rates. If this bothers you, you might try encoding or transcoding your conttent more efficiently by either reducing the encoding dimensions or limiting the encoding data rate setting. Unfortunately, many "modern" MPEG-4 AVC encoders have the potential to create files with data rates as high as 720 Mbps and some users tend to use unrealistic "quality" settings for the content they create. For instance, the average BD is encoded with a data rate on the order of 20 Mbps (MPEG-4 AVC) to 30 Mbps (VC-1) while the same 1080 video may perceptually look just as well using anamorphic encoding with data rates in the 5 to 13 Mbps range and 720p versions can frequently play very well in the 1.6 to 3.5 Mpbs range. Such encodeing strategies. In short, lower data rates allow smoother playback and smaller files at the potential expense of quality. The question then becomes, "Which aspect is most important to you depending on the targeted use of your files?"

Drop frame error message during playback

HELP! There is absolutely NO reason this should be happening. My time line will playback for about a minute or two and I get this error message about dropped frames (lower your real-time playback, close open sequences, etc. blah, blah).
I'm editing a HD 720P60fps project, with no files to render. My output settings are correct for my HD flat screen and my reference monitor. I'm using a Matrox MXo2 box for my A/V input/output, with the latest version of software, etc. SDI out to my reference and HDMI to my Panasonic Plasma.
I'm totally stumped at this point. any help will do. Usually easy set-up works every time, but it hasn't so far...thanks.
I have an Intel G5 Mac. Version 10.5.6 of Leopard. 2 x 2.8 GHz Quad-Core Intel Xeon processor. 10 GB of 800 Mhz ram.

You gave us a lot of information, but not where the media is stored. What sort of hard drives are you storing this media on? That is a HUGE factor in dropped frames issues.
EDIT: OOP...this didn't go thru fast enough...hee..

I am getting "The contents cannot be displayed in a frame" error when tried to acces an external URL configured through launchpad(ESS). How to rectify it?

Hi Guys,
We have configured ESS role through launchpad. For viewing payslips we are using an external URL configured through launchpad.
But when we try to access the configured link in ESS role, it displays "The contents cannot be displayed in a frame" .
Should I need to change some parameters/settings in Launchpad so that I could overcome this issue.
Guidance required,

Hi Shankar Reddy Chamala,
Thanks for the alternate solution.
But the solution you have provided also ended up with the same error
