FCPX-to-Compressor V4 performance question (which is better?)

For a 15-minute movie, I go directly FILE=>SEND TO COMPRESSOR and it takes about 4-5 hours to produce a MP2 file for DVD. That's grinding four 3GHZ processors to 100%.
Alternatively, if I FILE=>SHARE=>MASTER FILE it takes about 10 minutes to create the .MOV file. If I then input this intermediate .MOV file directly into COMPRESSOR, I can create the MP2 file in about 10 minutes.
So my question is: If I create the intermediate .MOV file, will I lose some quality instead of going directly from FCPX to COMPRESSOR?
Thanks for your thoughts

It's theoretically a cleaner encode going directly from FCP to Compressor. Each frame is called up from FCP from the original media, processed and then encoded. The original file is processed in fully uncompressed, 32-bit float format. It's very clean but it requires the OS to basically switch back and forth between the two applications frame by frame. It's great, but it's very slow. The fact is with near lossless codecs like ProRes the difference between the two methods is not discernible without frame by frame comparison. If you've got all weekend to encode your movie you may as well go ahead and do it. Personally I like having a master file anyway, so if I ever need to make different versions in different formats, it's much easier to go just go back to the master file and re-encode from there than to have to go back to FCP to encode again. You'll probably find discussion about this going back a few years on the Final Cut Studio forum here or on the equivalent forum on Creative Cow and probably other places as well.

Performance wise which is better NOT IN or NOT EXISTS.

also that not exists is not equivalent to not in

no rows selectedin most case, Oracle internally rewrite a NOT IN in a NOT EXISTS, because NOT EXISTS usually performs better.

Question: Which is better and why....RMAN catalog or Flashback Recovery

Hey All,
Newly testing and reading up on 10g. I am on information overload and would appreciate pro's advice on which to choose and why.
Thanks,
d.

Different things, not necessarily alternative. That is, RMAN catalog is normally (at least should be) on another machine, and does not contain physical backups, but only information about them : physical backups are normally stored on external devices, like tapes.
Flashback Recovery technique is based on Flashback logs in Flash Recovery Area, which is a disk area on local machine, and so cannot be unlimited.
Therefore, Flashback Recovery is much faster than Media Recovery, since you don't need to restore anything, but you have limits in using that : your disks size.
On the other hand, RMAN backups are safer, being physically elsewhere.

I have a Question which is better to design a flyer for a furniutre store

i can work with Photoshop which i know best, or Illustrator or indesign i need help please !

I would use Illustrator for the document setup. Plenty of fire power using typography tools, color, etc. Believe it or not, I still start with a sketch or a rough pencil comp and show those if necessary. Once the layout has been approved, then I can move on to preparing image files ( Photoshop ) at 100% final size for "Placement" into either Illustrator or InDesign. I like Illustrator because it is faster ( for me ) and I can create a final PDF on the fly. I would avoid doing any type of print work all in Photoshop. File size and manageability quickly become issues. How many images are you planning to use in the flyer? Have you decided on a print vendor yet? If so, discuss the project with them and get their file requirement checklist.
And, take a look into Adobe's "Print Publishing Guide" for more info. A very helpful resource.

In theory it depends on circumstances.
Correlated EXISTS subqueries tend to be efficient if the lookup is properly indexed. If the list of values is very small (especially if you only get one value) an IN subquery might be more efficient.

Minimum Macbook Pro for FCPx and Compressor

I do most of my video work on an 3.4 Ghz i7, 16GB iMac, but I'd like to be able to use a Macbook Pro, when traveling or for handing off tasks to a secondary machine. My current Macbook is looking like it's on its last legs so the time is arriving to replace it with an upgrade.
So my question is, what is the minimum configuration for a Macbook Pro and still have it be usable with FCPx and Compressor? I'm thinking the base model 15" is probably enough or an upgraded 13". They end up at about the same money.

Which is what I did with my iMac -- it was the maximum horsepower I could buy at the time. I always use proxy media just for the speed of editing. With the Macbook Pro it will never be my main tool, just a fallback, a traveling machine, or a place for handling Compressor tasks when I'm busy with something else.
I will check out the FCPx marketing info as I didn't think to look there. Usually minimum requirements translate out as "barely workable configuration".

No optical flow going from FCPX to Compressor

Using Compressor 4.1.3 and FCPX 10.1.4. When I export a project from FCPX to Compressor, and the project has some clips with Optical Flow, Compressor does not render those clips using Optical Flow. Using "Apple Devices HD (Best Quality)" setting.
I searched for similar questions, both here and in the FCPX forum, and didn't find any similar questions, which leads me to believe that either I don't know how to search properly, or I must be missing something obvious.
Any help is appreciated. Thanks.

Your experience matches what others have reported. Alternatively you could export a master file and bring that into Compressor to apply your settings. In other words, skip the Send to Compressor workflow altogether. Or export directly with ATV settings from FCP X

Which is better? Code comparsion of performance and style

Recently I run into a discussion over a small piece of code. Could help me which is better, either in performance or coding style? The code is not complete, the question is the use of local cancellationNumber variable.
public String cancelAction(/**/) {
/* some code */
        String cancellationNumber = result.getCancellationNumber();
        if (empty(cancellationNumber)) {
            throw new Exception("Did not receive a cancellation number!");
        return cancellationNumber;
    }or
public String cancelAction(/**/) {
/* some code */
        if (empty(result.getCancellationNumber()) {
            throw new Exception("Did not receive a cancellation number!");
        return result.getCancellationNumber();
    }

Yes, I know profiling can be misleading, also compiler optimization adds to the picture. However seeing the numbers differentially, I think there is still some information, which is faster, even if taking it completely out scope. I didn't paste the code, because it's so trivial. I run the two methods in a loop with same arguments.
With increased loop count, the difference is 6-7%, cancelActionWithLocal being faster. But this can be pointless, I know.
package org.helloprofile;
import static org.helloprofile.Util.empty;
import java.util.Locale;
public class CUT {
    public String cancelActionWithoutLocal(Locale locale, String email, long itineraryId, String confirmationId) throws Exception {
        Result result = new Result();
        if (empty(result.getCancellationNumber())) {
            throw new Exception("Did not receive a cancellation number!");
        return result.getCancellationNumber();
    public String cancelActionWithLocal(Locale locale, String email, long actionId, String confirmationId) throws Exception {
        Result result = new Result();
        String cancellationNumber = result.getCancellationNumber();
        if (empty(cancellationNumber)) {
            throw new Exception("Did not receive a cancellation number!");
        return cancellationNumber;
}Thanks for the comments!

FCPX to Compressor 4.1 to WMV (using Flip4Mac) - Audio Popping Noise

This week I exported WMVs from FCPX 10.1.3 via Compressor 4.1.
A strange 'popping noise' appeared in the final exported files that was not present in the original source clips in FCPX.
I ran through every conceivable AV quality setting in the Windows Media Quicktime Export Components to isolate the problem but to no avail.
To humour myself I used a free online WMV conversion tool which produced a WMV that didn't have the audio popping noise.
Eventually I contacted Telestream/Flip4Mac and asked if anyone else had reported the issue.
They said they had started to receive reports of similar problems occuring when exporting to WMV from Compressor.
THE SOLUTION:
Export a ProRes MOV from FCPX via Compressor
Open that MOV in Flip Player and select Export > Format > Windows Media

This is what I see.

1080p 50 footage to Blu ray appears to convert to either 1080p 25 or 720p 50 is Share FCPX or Compressor

Has anyone been able to burn 1080p 50 footage to Blu ray, I can only seem to create a file of 1080p 25 or 720p 50 in either FCPX or Compressor 4 as the 50 option is greyed out in 1080p. As far as I can tell most blu ray players can handle AVCHD 1080p 50, even after the latest upgrades this still does not work. The footage is on the time line and project properties are correct.

wrong assumption.
'Disks' (BR/DVD) are completely different encoded than the stuff in your timeline.
To keep things simple, the rule is:
length matters, not size.
A single-layer DVD with maximum quality settings fits ~60min of video.
And, due to standards, is always SDef.
Same disk fits ~20min of HDef in a sort of BluRay-standard = you can burn a BluRay-structure onto DVD-r ... not fully compatible, but for 'quick'n dirty'.
Same DVD-r fits only a minute as 'data' from your timeline, which probably is encoded in proRes = ~40GBs/h ......
forget size ........ think of hh:min:sec

Just fancy asking some questions which i have never really thought about

I just fancied asking some basic questions which i have never really thought about, but suppose i should know.
The first one is:
A java program is executed through the main method
public static void main(String[] args)So this method is passed a String array but i never pass the array to it, so who does?
And secondly, you can have variables of type int and variables of type Integer. What is the difference?
thanks

I'll take a stab with some overly-simplistic answers. Corrections most welcome.
A java program is executed through the main method
public static void main(String[] args)So this method is passed a String array but i never pass the array to it, so who does?The OS passes the parameters to the JVM and the JVM calls the main method with the parameters from the OS.
And secondly, you can have variables of type int and variables of type Integer. What is the difference?Integer is a wrapper class for the primitive int type. It allows you to use int-type concepts in places where an Object is required. But don't over-use these as there is a memory and performance overhead that must be taken into consideration.

Xcontrol: performance question (again)

Hello,
I've got a little performance question regarding xcontrols. I observed rather high cpu-load when using xcontrols. To investigate it further, I built a minimal xcontrol (boolean type) which only writes the received boolean-value to a display-element in it's facade (see attached example). When I use this xcontrol in a test-vi and write to it with a rate of 1000 booleans / second, I get a cpu-load of about 10%. When I write directly to a boolean display element instead of the xcontrol,I have a load of 0 to 1 %. The funny thing is, when I emulate the xcontrol functionality with a subvi, a subpanel and a queue (see example), I only have 0 to 1% cpu-load, too.
Is there a way to reduce the cpu-load when using xcontrols?
If there isn't and if this is not a problem with my installation but a known issue, I think this would be a potential point for NI to fix in a future update of LV.
Regards,
soranito

Okay, I think I understand question now. You want to know why an equivalent xcontrol boolean consumes 10x more CPU resource than the LV base package boolean?
Okay, try opening the project I replied yesterday. I don't have access to LV at my desk so let's try this. Open up your xcontrol facade.vi. Notice how I separated up your data event into two events? Go the data change vi event, when looping back the action, set the isDataChanged (part of the data change cluster) to FALSE. While the data input (the one displayed on your facade.vi front panel), set that isDataChanged to TRUE. This is will limit the number of times facade will be looping. It will not drop your CPU down from 10% to 0% but it should drop a little, just enough to give you a short term solution. If that doesn't work, just play around with the loopback statement. I can't remember the exact method.
Yeah, I agree xcontrol shouldn't be overconsuming system resource. I think xcontrol is still in its primitive form and I'm not sure if NI is planning on investing more times to bug fix or even enhance it. Imo, I don't think xcontrol is quite ready for primetime yet. Just too many issues that need improvement.

Using FCPx and Compressor dvd stutters

Using FCPx and Compressor I have put a 2 minute film on a dvd but when I play the dvd it stutters irregularly. I have tried lots of different settings and need HD quality. Can anyone help please? Thanks Helen

Are you putting a ProRes file on a standard DVD? You can't play it back. The DVD disc his nowhere near the through put needed to support high data rate media. The DVD format is very heavily compressed to allow proper play back, which that can be managed off the disc.
