Choppy and Dropping Frames with AVCHD on FCPX

Hi,
I'm having a nightmare problem with AVCHD on my Mac Pro and FCPX.
So I'm editing with 1080 60p from FS700, NX70, GoPro Hero3 and XR-550V.
Imported without transcoding first, so just a rewrap into QT.
Tried to play a single clip in the events or timeline in this conditons:
- "Use original or optimized media" > High Quality
- "Use original or optimized media" > Better Perfomance
- "Use proxy media" (and did a transcode only for 4 clips to test)
With all those possibilities it ALWAYS plays choppy and dropping frames.
Playing in the QT (PRIVATE and choosing the clip) plays normal.
Playing in the QT proxy transcoded from FCPX plays normal.
Using Premiere CC is also normal.
Tried to ensure that the timeline is 29.97p, same thing (dropped frames choppy).
What could it be?
Specs:
FCPX 10.0.9
Mac Pro Early 2009
Original Material in a RAID0 ~220MB/s R/W
Processor 2.66 GHz Quad-Core Intel Xeon
Memory 7 GB 1066 MHz DDR3 ECC
Graphics NVIDIA GeForce GT 120 512 MB
Software OS X 10.8.5 (12F45)

Well, it's possible for FCP to find something about either your hardware (or a third party software) problematic and for Pr to be OK with. Premiere has long been more agnostic about formats and codecs than FCP.
Unsure what to suggest. It shouldn't require the latest-greatest ;for example, we have a four year old MBP, running Lion that can play 1080 AVCHD smoothly… although we set Preferences to better performance.

Problem with source tape and drop frames with capturing HDV

I am having trouble capturing a tape. Every time I try and capture I get the message problem with tape, I try to change settings but after a few seconds of capturing the capture stops. I know that the tape is fine so it does not have anything to do with my tape. Capture also stops because it comes up with a message saying drooped frames.

Are you capturing to an external or secod drive, right? What kind of drive? What camera?

FCPX green frames/artifacts and dropped frames

I have been trying to use FCPX for a couple of weeks now, but haven't been able to. I constantly get green frames/artifacts and dropped frames during playback AND export regardless of using optimixed or proxy media. I am importing mp4 quicktime files, in case that is important.
I am using:
MBP (mid 2009)
OSX 10.6.8
Intel Core 2 Duo @ 2.26 ghz
2 gb ram
Nvdidia GeForce 9400M w/256 vram
I know that it is reccommended I have 4 gb ram, but I meet the minimum requirements and cannot even use the program! Would upgrading to 4-8gb ram resolve this issue? Or is my processor the culprit?
Any help is greatly appreciated.

You DEFINITELY need to upgrade your memory to 8GB, etc. Otherwise you will not likely be able to get much real work done at all ... but ... that is likely not exactly the problem you are experiencing now . Since you are talking about bringing in MP4 files, I am thinking you did not get them from a tape-based camcorder. If you did, then they were converted to MP4 afterwards somewhere. Can you play the MP4 files in Quicktime and not see any green screens? If so then have you tried using the FCP X File/Import ... Files command to bring them into FCP X? I have used this with MP4 files without a problem. If Quicktime can play them okay without green frames, and FCP X cannot then the problem does seem to be in FCP X. Are your preferences set to use optimized media? If so then FCP X will convert the files to ProRes and the timeline playback should be okay. There are other "green frames" discussions here that you could also reference. These are just some thoughts.

Problems working with non drop and drop frame DVCPRO HD material in project

I am having playback problems with my non drop frame HDV material. It stutters.
All of our projects up to this point have been shot in drop frame. During our last shoot however the Bcam was recorded in non drop. I loaded both the non drop bcam tapes as non drop and the drop frame Acam tapes as drop. All of the drop frame Acam material plays back fine in the source viewer and the timeline. The non drop Bcam material seems to randomly stutter in the source viewer, or causes the system to serve a "dropped frames warning" in the timeline.
Is there a bug with fcp 5.1.2 about mixing non drop and drop frame material in a project. Or is this not possible? They are the same frame rate.
I have exported the non drop clips in a drop frame timeline and re-imported them as drop frame clips - thus correcting the problem. Is this the best solution?
All of the material was loaded thru a kona card as 1080i60 DVCPROHD 29.97
I had no problems capturing the material as long as I used the corrrect firewire setting (ndf vs df).
Anyone have a problem like this? I would greatly appreciate a response.
Thanks,
Mark

The camera can record 60i, and 30F:
"HDV 1080, 50i/60i/30F/25F Recording and Playback capable"
Look at the clips...look at their frame rates. What do they say? Is one 59.94? Is the other 29.97?
You would never need to render if you mixed NDF and DF footage. The footage runs at the same speed, on the TC numbers are different. But, you would need to render if your footage had different frame rates. LOOK AT THE CLIPS.

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.

Dropped frames with HD

Is it possible to edit HD with final cut HD and not have any dropped frames?
It is impossible to get a smooth slow-motion clip let alone one in real time.
If there is a fix or some technich to prevent this?
thanks-
Jake
Mac Book Mac OS X (10.4.7) 2 GHz intel Core Duo. 2 GB RAM

Well, there are lots of things that can cause dropped frames, but I think it's pushing the envelope to be doing HD on a MacBook. Don't take this the wrong way - I think MacBooks are great machines. But HD requires a lot of computing power and even though the MacBook is qualified for FCE-HD, given the MacBook's Intel GMA video processor/shared memory and 5400rpm HD, I wouldn't be surprised to get dropped frames with HD material.
On the other hand,
-how full is your system HD
-are you using an external hard drive by any chance
-have you rendered your material or are you relying on RT effects
-have you mixed down your audio
-do you have any other apps running at the same time as FCE

Slow drive and dropped frames

Hi help!
I've just finished an edit using fcp 6 .. 1.5hrs long / using 3 camera multiclip .. no problems.
I've cleared that out, and this time have a 2.5hr project / similar 3 camera multiclip, and I'm getting error messages every 10 secs, about slow drive and dropped frames!
Nothing except for the source material (which I reloaded)has changed, so has anyone any idea of what could be happening?
Thanks,
P

Pete
I'm pretty sure the USB is the cause of the droped frames, not enough band width and USB don't manage continous flow of data like FW, it sends/receives chunks of info. They are not suitable for video editing and it will be worst with multiple streams of video at the same time.
You must try at least a FW400 drive.
Hope that helps !

A drag and drop game with dynamic text response

Hi,
I am a teacher and my school has recently upgraded to Adobe Design Premium. Our previous version was about 5 versions out of date.
I teach A Level which requires students to create an Interactice Multimedia product.
In the previous 6 years, I have taught students how to create simple drag and drop game with dynamic text responses.
Since the upgrade to Actionscript 3.0 the dynamic text response has ceased working.
When creating the game from scratch, I need to move to Actionscript 2.0 as 3.0 does not allow me to add actionscript to objects - I know and am sure that this is a better way of doing things, but I would prefer to keep working the way I am used to.
I use a switch case statement which I have copied below to make the drag and drop work. The objects I apply the code to work in that they can be dragged, however, my dynamic text box with a variable name of "answer" is no longer displaying the response when an answer is left on a dropzone (rectangle converted to a symbol and given an instance name).
on(press) {
startdrag(this);
on(release) {
stopdrag();
switch(this._droptarget) {
case "/dropzoneB":
   _root.answer="Well done";
   break;
case "/dropzoneA":
case "/dropzoneC":
   _root.answer="Hopeless";
   break;
default:
   _root.answer="";
   break;
Any help would be much apeciated.
Thanks

To drag in as3
blie_btn is the instance of the object drawin on the stage. In AS3 you have to assign a even listener, in this case MOUSE_DOWN, and MOUSE_UP, as we want the drag to stop if the mouse is not clicked. Then we fire the functions, and tell the object to start drag.
// Register mouse event functions
blue_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
blue_btn.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
red_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
red_btn.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
// Define a mouse down handler (user is dragging)
function mouseDownHandler(evt:MouseEvent):void {
     var object = evt.target;
     // we should limit dragging to the area inside the canvas
     object.startDrag();
function mouseUpHandler(evt:MouseEvent):void {
     var obj = evt.target;
          obj.stopDrag();
if you want to make the text do what you want then something like this might work.
In the function, you could add a text box onto the stage, give it a instance of something like outputText
and then:
outputText = ("Bla Bla Bla");
(^Not sure if this will work exactly^)

Drag and Drop objects with JavaFX properties

Has anyone tried to implement drag and drop functionality with objects containing JavaFX properties? The issue I'm running into is that the objects appear to need to be serializable, and the JavaFX properties are not serializable. I can implement Externalizable instead of Serializable, and basically serialize the values contained by the FX properties, but of course I lose any bindings by doing this (as the listeners underlying the bindings are not serialized).
The [url http://docs.oracle.com/javafx/2/api/javafx/scene/input/Clipboard.html]javadocs for Clipboard state "In addition to the common or built in types, you may put any arbitrary data onto the clipboard (assuming it is either a reference, or serializable. See more about references later)" but I don't see any further information about references (and at any rate, this doesn't really make sense since anything that's serializable would be a reference anyway). Is there a special DataFormat I can use to specify a reference in the local JVM so the reference gets passed without serialization?
I know this might not make sense without a code example; I just thought someone might have come across this closely enough to recognize the problem. I'll try to post a code example tonight...

Here's pretty much the simplest example I can come up with. I have a real-world example of needing to do this, but the object model for the real example is quite a bit more complex.
For the toy example, imagine we have a list of projects, some employees, and we want to assign each project to one or more employees. I have a Project class with a title and assignee. (In real life you can imagine other properties; due date, status, etc.) I'll keep a ListView with a bunch of unassigned projects (titles but assignees equal to null) and then a ListView for each of the employees.
To assign a project to an employee, the user should be able to drag from the "master" list view to one of the employee list views. When the project is dropped, we'll create a new project, set the assignee, and bind the title of the new project to the title of the project which was dragged. (Remember we want to be able to assign a single project to multiple employees.)
So here's the first shot:
A couple of simple model classes
Project.java

import java.io.ObjectInput;

     private final StringProperty title ;
     private final ObjectProperty<Employee> assignee ;
     public Project(String title) {
          this.title = new SimpleStringProperty(this, "title", title);
          this.assignee = new SimpleObjectProperty<Employee>(this, "assignee");
     public Project() {
          this("");
     public StringProperty titleProperty() {
          return title ;
     public String getTitle() {
          return title.get() ;
     public void setTitle(String title) {
          this.title.set(title);
     public ObjectProperty<Employee> assigneeProperty() {
          return assignee ;
     public Employee getAssignee() {
          return assignee.get();
     public void setAssignee(Employee assignee) {
          this.assignee.set(assignee);
     @Override
     public String toString() {
          String t = title.get();
          Employee emp = assignee.get();
          if (emp==null) {
               return t;
          } else {
               return String.format("%s (%s)", t, emp.getName()) ;
}Employee.java

     private StringProperty name ;
     public Employee(String name) {
          this.name = new SimpleStringProperty(this,"name", name);

          return name ;

          return name.get();

                    setOnDragDetected(dragDetectedHandler);
}If you try to drag from the list on the left to one of the lists on the right, it will fail pretty quickly and tell you that the data need to be Serializable.
Simply adding "implements Serializable" to the Project and Employee classes doesn't work, as you find that SimpleStringProperty and SimpleObjectProperty are not Serializable. So instead I can use Externalizable:
public class Project implements Externalizable {
@Override
     public void writeExternal(ObjectOutput out) throws IOException {
          out.writeObject(title.get());
          out.writeObject(assignee.get());
     @Override
     public void readExternal(ObjectInput in) throws IOException,
               ClassNotFoundException {
          setTitle((String)in.readObject());
          setAssignee((Employee)in.readObject());
}and
public class Employee implements Externalizable {
     @Override
     public void writeExternal(ObjectOutput out) throws IOException {
          out.writeObject(name.get());
     @Override
     public void readExternal(ObjectInput in) throws IOException,
               ClassNotFoundException {
          setName((String) in.readObject());
}This makes the drag and drop work, but if you drop a project on one of the employee lists, then edit the project title in the master list, the binding is not respected. This is because deserialization creates a new SimpleStringProperty for the title, which is not the property to which the title of the new Project object is bound.
What I really want to do is to be able to drag and drop an object within the same JVM simply by passing the object by reference, rather than by serializing it. Is there a way to do this? Is there some DataFormat type I need?

Capture Direct to External HD/Dropped frames with Firewire-In and eSATA-Out

I have been working on a setup with a brand new 2.6 GHz MBP/4 GB/200 GB-7200rpm HD. I am capturing DVCAM via Firewire400. I am capturing direct to a LaCie Biggest Quadra connected to an eSATA PCI card. I keep encountering dropped frames on capture. Could this be due to the PCI connection? To the best of my knowledge, the PCI slot is a separate bus from the Firewire bus, which should avoid the pitfalls of i/o on the same Firewire bus. What could be the problem here? Thanks in advance.

If you have a MacBook Pro, then yes the ExpressCard bus is separate form the firewire bus. The pros here ALWAYS recommend capturing via firewire to a different bus, either firewire or eSATA via an ExpressCard (or PCI for the previous generation laptops) since the card is on a different bus. Have you tried attempting a capture to the inter drive? I know this is in no way ideal, but this way, we can rule out the camera/deck. DVCAM also isn't much bigger than DV if at all, so bandwidth shouldn't be a problem. Again, not ideal, but try connecting the big disk to the other firewire port on your MBP. This way we can rule out the eSATA card. Report back and we'll see what else we can do to help.

Avoiding dropped frames with Matrox and HD Video

What is the best hard drive configuration to avoid dropped frames when using a Matrox MXo2 mini for HDMI outpjt to a high res monitor/tv? I am experiencing slow performance with the four drives in my Macpro 3,1 3Ghz 30GB Ram Nividia Cuda card. I am after about 200-250 MBytes/sec transfer speeds. Can I do this with two identical disks in my Macpro and configuring them for Raid 0. Or do I need to do it externally? I have increased speed to about 120 MBytes/sec by using a Esata card and connecting into to a Lacie 2TB Big disk,configured for Raid 0 . I need to go a bit faster than this....especially if I want to use premier

Those are nice looking enclosures and in general I like OWC. I've been using their stuff since before the turn of the century.
But in this case, I don't think you'll get the speed you're looking for because they are using eSATA and muxing the data over a single cable. It's a flexible solution, but not a very fast one. To re-iterate, the two flaws I see are:
1. SATA II disk speed, and
2. a single eSATA cable
This could theoretically provide 300MB/sec, (they have a benchmark that is around 250) but don't look for it day-in, day-out. As the drives fill up and reality settle in I doubt you'll see the numbers you want. BUT... maybe it'll provide enough.
Instead, take a look here:
SATA Enclosures - PC PitStop
Not quite as sassy looking, but I've had the first enclosure shown running with four spindles and a SFF-8470 multilane cable since 2006. And it still benches over 250MB/sec mostly loaded on the original drives.
Any of the enclosures on that page will support SATA III drives and they offer a variety of controllers.This isn't a big shop but they know what's up. Call them. I know I can build a RAID with their stuff that will cost about the same as the OWC box and be seriously faster.
Hope this helps

Client Monitor Dropping Frames with a GTX 570?

I have a 2 monitor setup which are both connected to my GTX 570. I edit on one monitor and play HD video full screen on the client monitor. The video was shot on my Panasonic GH2. Premiere Pro CS5.5 would play this video silky smooth but CS6 drops frames so badly that I woldnt be surprised if it was playing 12 frames per sec.
When I turn off CUDA accleration the video plays a lot smoother.
Is anybody else having this problem?
P.S. I have the latest Premiere Pro update os 6.0.1 and I am using the latest Nvidia drivers. I even installed the older drivers that I was using with CS5.5 and the video is still dropping frames like crazy.

This is a known problem with AVCHD and maybe other codecs. The new 6.0.1 helps but does not completely eliminate the playback problem, which I see especially after scrubbing. Maybe your video is more compressed than mine is. See also This thread

Logging clips and drop-frame.

Hey All,
I guess it’s time for me to learn something new today:
I jut logged four hours worth of Mini DV shot NTSC Anamorphic. I thought I did everything as I usually do but I’m getting a Warning: You are about to capture drop-frame media to a non drop-frame clip…
I checked the logged clip format and there is no vid rate specified. I tried to add 29.97 but FCP won’t let me.
So, is there a way for me to correct this without having to re-log all the clips?
And, where did I go wrong to have this happen in the first place?
THANKS!

I guess the question is solved. With the tape in the camera I don’t get the warning.
Thanks anyway...

New Intel iMac, FCE 3.0 and dropped frames on capture

Just got a brand new 20 inch iMAC running 10.4.9 with 2G of RAM and over 200G of space. Can't capture more than a minute or two of footage to the hard drive without a dropped frame abort.
Have no problems capturing the same tape to a nearly full Lacie external drive through my 4 year old inverted bowl G4 running 10.3.9 with only 512 MB of RAM.
Does anyone know if it could be because I am running FCE 3.0 on the new iMAC? I've read that 3.0 is not made for the Intel and that the machine has to do some behind-the-scenes tricks to make it work.
Might upgrading to 3.5 solve my capture problem?

I think that article is misleading. It seems as if that if you have 3.0 or earlier (FCE, of course), combined with OS 10.4.9, no matter WHERE you capture to, you will get dropped frames. There are three (3) solutions, and they are as follows:
1. Archive and Install to 10.4.8
2. Buy the upgrade to 3.5.
And the newest one, though not tested by many people:
3. Drag and drop the drive that you capture to in Spotlight's Privacy window. That's in System Prefs.>Spotlight>Privacy.
I can't test the 3rd one as I have 3.5.

Flash player drops frames with playing live h264 frames

Hi
i have been tryin to get to a adobe representative for a long time now regarding this but unfortunately no one responds fast enough. I am facing a terrible issue. When broadcasting h264 live video from a flash based encoder client i notice severe frame drops on the playback end no matter what player i use. It even happens if i use fms development server on my own system. Video becomes smooth if i add a 1 sec buffer to the player. but then the video is no longer live.
So my question is , is theer somethign wrong with h264 encoding in flash player or thats the way it is suppose to be ? at zero buffer frame drops are severe. Sample config :
320 x 240 @ 24 fps @ 90000 bps @ 100 KFI @ 3.1 level @ baseline profile.
I sincerely some one at adobe to respond. There are many stranded questions on this topic on the forum and on the web already.

The CPU usage is 2-6% on the i7 920 vista 64bit computer. The audio doesn't seem to be dropping. Some more clues that might help you help me
- The quality of the video doesn't matter, 360p drops frames just as often as 720p or 1080p.
- The dropped frames still occur even when the video is completely downloaded and replayed without any buffering needed.
One thing that does fix the dropped frames is completely disabling my sound card in the windows playback sound options. This also fixes the second computer's dropped frames which only has onboard realtek audio. I have tried using a Creative PCI sound card and the built in realtek sound but they both behave the same. The latest drivers were installed for both.
