Need help on upconverting interlaced to progressive

Well I've searched and read as many related threads as I could find, I've also search the web and read a bunch of articles, but I still don't quite feel I understand nor have an simple answer and hope someone here can enlighten me.
And yes, I'm a newbie with FCP, Compressor, and DVDSP so please keep that in mind.
Basically I have DV stuff in NTSC 480i that I would like to upconvert to 480p to then use in DVDSP and eventually to be seen on a regular old DVD player (progressive scan of course).
I have successfully used the great tutorial (http://www.proapptips.com/videos/DV_to_DVCPROHD.mov) on upconverting to DVCPRO HD, however I wish to have the video in mpeg2 since (as stated) it's final destination is a mere "old fashion" DVD.
Some may say why bother with progressive but my thinking is that since I am already encoding to mpeg 2 doesn't it make sense to at least slightly improve the output to 480p?
Again, since I'm a newbie please correct me if I'm wrong. However if this makes sense, please just let me know which settings within Compressor I need to set to accomplish this (again, I'm a newbie so please be overly detailed if possible)
Thanks in advance.

The key should be stored in the keychain. You can check to see if it's being stored there by using Keychain Access in the Utilities folder. If you see an entry for your WEP device (usually the router name) then you might try deleting it and reconnecting to see if the password will store properly upon remaking the keychain entry.

Need help with combing/interlacing

Hi all!
My first time here!
I am having a serious dilema.
I make films using Super 8 film, have it digitized, then I edit the footage in iMovie, usually. I own Adobe Premier Pro CS4, but haven't needed as involved a program so far for my very basic editing needs.
Here is my dilema:
I made a movie for a client and the footage was (for some reason) interlaced when the company in LA digitized it for me and burned it to my hard-drive. So, my original files that I imported into iMovie are interlaced.
While working on the movie in iMovie, and then watching it on my computer or online it looked perfect. However, the client just informed me that there are "weird horizontal lines that show up on their film when they watch their DVD". Not sure if they have a blue ray player and an HD tv, but I assume so.
My question is, do I need to deinterlace the original footage and reedit the film from scratch using Premier, (and if so, how do I deinterlace the footage),
OR
can I somehow import the final film I gave my client and deinterlace that already edited version?
As a side note, iMovie doesn't give a ton of options when you export the film, so I'm not 100% sure what my settings were when i exported it, probably the default settings?
Any help anyone can give me would be SOOOO appreciated!!
Thanks in advance..

The .moi files are only indexes. The actual video will be in .mod files. These are a problem.
Some users have reported success using MPEG Streamclip to convert them to QuickTime/Apple Intermediate Codec.
Since .mod files are actually MPEG2 in disguise, you may need to get the Apple QuickTime MPEG2 Playback Component ($20 download from Apple) in order to enable MPEG Streamclip to convert them.
One other thing, don't just copy the .mod files off the memory card. You need the entire folder structure.

Need help/advice/info on displaying progress msg in multithreaded MIDP

So I have this kind of MIDlet:
1. Using multi-threading feature to access remote web service/JAX-WS. The threads retrieve strings from GlassFish, connected to a MS SQL Server 2008 database.
2. The retrieved strings are to be stored within the MIDlet's RMS. Done perfectly until this phase.
3. The buggy thing is, WHILE the retrieving threads are alive/running and storing strings to RMS, I want to display some progress messages/bars to a Form by StringItem/TextField.
So I thought- it may be caused by the thread deadlocks, but it's not. WITHOUT the RMS storing strings, it flows OK.
(Because the progress msg alteration to the Form is done (I think) by my created threads, thus no deadlock occured.)
But WITH the RMS operating, it freezes on the "Confirmation/Yes-No" Form right before I press the Yes button.
Only when the whole threads are finished/terminated, it's then jumped to "Process Completed" Form.
(I get the feeling it jumped to each progress msg by miliseconds RIGHT AFTER all threads are finished, then to "Process Completed"
which is something I don't want to happen)
So I'm wondering how to get around this prob? Whose thread is it that operating the RMS?
Thanks.

hi, i have an application which takes pretty long to
run. The process basically consists of several sql
statements. My idea was to display a message box just
before the process starts saying something like "in
progress... please wait". Anyway i created a message
box using jdialog but the problem now is, it just
displays and empty box, the message is displayed only
when the process has finished running which is
useless. if i use the msg box elsewhere, it runs just
fine, only when it is placed before a block of long
running code (e.g a very big loop) it just does not
display the text.
Can anyone please advise me on this issue, thanks!If you don't want to get into threads and things like that, try the following?
1. Add some delay between the message box request and start of the query.
Like
for (int i = 0; i < 100000; i++) {} // you have to experiment with the limit. A second's worth should be enough to see if this makes any difference.
2 Add the method repaint(); after the message request.
3 Add the method repaint(); and delay after the message request but before the query request.
LIke
// message display request
repaint();
for (int i = 0; i < 100000; i++) {}
// query
What's interesting to me is that an empty box is drawn. So my guess is if enough time (a second say) is given, the message box will be drawn completely. (Of course, I'm not sure.)

Need help on P6 v8.1 Progress Reporter installation / configuration issue

Successfully installed P6 EPPM v8.1 on Win 2k8 ent. for evaluation. However, upon completion of the progress reporter configuration an internal server is encountered.
I can successfully navigate to https://<ip>/pr page. However, when you click on the "Launch P6 Progress Reporter" link, the error 500 is presented
Error 500--Internal Server Error
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.5.1 500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.
The setDomainEnv changes outlined in the administrators manual have been completed.
The database configuration has been completed and the server was restarted. (https://<ip>/pr/admin/configuration) however a couple of observations:
If I change the configuration home location the configuration does NOT stick, that is when I log back in to the pr admin configuration page I would expect to be able navigate to other tabs (i.e. connection pool, authentication, logging) but I cannot. ONLY upon accepting the default configuration home, does this take and the other tabs are presented after the restart.
Additionally, if I select to increase the logging through the admin configuration screen, and click save, then the same error 500 page is presented (see above).
Have also tried to use the http://<ip>/pr/applet?lang=en no success.

I restored my iphone and updated it but the progress didn't complete and now my iphone is not working. i need help asap.

my phone was not working only the restore button was available so i restored it and they told me i have to update my iphone 5s as well. i waited till the end the update software was downloaded successfully but then the iphone restarted by itself and now its not working. the iphone screen is shown the picture when you first time open the phone to connect it to an itunes. i connected it by it not working, i restart everything still not working:( i need help asap please. thankyou

it seems like apple's activation servers have gone down under the weight of the overwhelming amount of activation requests. you will be able to activate your phone once the servers are able to catch up with the activation requests.

30p with a Canon XA10 - need help with Final Cut 7 "FIELD DOMINANCE" setting and an explanation of "drop frames". Thank you!!

I shot footage using a Canon XA10 and there are issues with the HD quality not looking as crisp as it should. I am trying to make sure the settings in Final Cut are right. Need help confirming what should be in "Field Dominance" --- have seen discussions about making sure it's set to "none" but I'm confused as to what to do.
Also someone suggested I use "drop frames" to change from 30p to 24p within Final Cut. He couldn't explain how to do it so any input appreciated as well as any thoughts on whether this is a good option to try.

If you're shooting 30p, field dominance should be set to none. Since you need to use log and transfer to bring this material in to fcp, I would assume it would be set correctly automatically. Are you sure you've set the camera properly?
Drop frames will not change 30 p to 24p. Dropframe timecode simply refers to the number assigned to each frame which drops an occasional number (not any frames) so the timecode duration is the actual duration, since 30p videoi is actually 29.97 frames per second which each frame assigned a timecode number.
This is very basic video stuff and requires some basic knowledge of video. Wikipedia is a pretty good resource for much of this stuff plus there are lots of great resources on the web. Look up interlaced and progressive video, 24p and 30p.
And as far as judging quality, you can only get an accurate view of the quality in fcp when you have a video card attached to a video monitor. The viewer and canvas are only an approximation of what the quality is. Minimally, set the canvas or viewer to 100% to get a better approximation of the quality.

Blurry titles when exporting from interlaced to progressive?

I have a project which is DV PAL (720 x 576) and needs to be exported as a progressive H264 mpeg file. The video looks good in the export, but the titles are blurry. I just did a test and exported the project interlaced, and titles were fine. So the problem is clearly the transition from interlaced to progressive. Is there any way to get crisp titles in this situation?
Using Premiere CS6. Have tried exporting to progressive with several alterations to the title clips (reversing field order, always deinterlace) with the same result.

Hi JR Dungan,
How about you create a new progressive sequence, and then copy paste all of the content of your current interlaced sequence into the new progressive sequence, and export from there. I haven't worked with interlaced footage for years so I don't know for sure if this will help or not, but since it's quick and easy to do, it's worth a try.
Cheers!

Need help with almost completed plugin engine project

Hi all,
For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
Look forward to some replies.

Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces.

Best way to work with interlaced and progressive clips in the same timeline

I´m shooting with Sony MC-50E camera in 1920x1080, 50i. When importing with Log & Transfer I can work with ProRes 422 files in interlaced mode. I have to mix the footage with video screencapture which is progressive (ProRes 422). The final videos are for web only so it should end up as progressive H264 videos. I´m getting good result if exporting to H264, 1024x576 with deinterlacing enabled, but exporting to full HD gives typical interlaced lines in the picture. How can I avoid this and what is the best solution for working with both interlaced and progressive clips?

Deinterlace in Compressor using Frame Controls, Best settings. You can reconnect the deinterlaced files to your project, if you've already edited, but you may need to copy and paste the clips in your sequence to a new 25p timeline, then Remove Attributes, Basic Motion.
When you're ready to export your sequence, use Quicktime Movie, Current Settings, Self-contained. Take that file to Compressor to transcode back to h.264.
The Apple T.V. preset is very good.

Video switching from interlace to progressive on render

We have a video 29.97 1920x1080i which we are running dynamic linked through after effects, and when we render the video out in premiere it is switching from interlace to progressive.
When the video, in the dynamic link is left un-rendered, we can see the fields in the video, they only disappear after render.
We have tried rendering into several different codecs, ProRes 422 (HQ) being our preferred codec.
Has anyone else experienced something similar?

The issue is present, even on our external monitors. I just had a chat with customer support, it offered little help:
Ankit Chillar: Please elaborate the issue you are facing.
Jack Savage: We have interlace media, which we are dynamic linking through after effects, and back in premiere, before we render the clip we can see that it is still interlace, but as soon as we render it, no matter what the codec, it renders into progressive
Ankit Chillar: What is the version of Premiere Pro and after effects are you using?
Jack Savage: cc 2014.2
Ankit Chillar: Hi, Checked this information for you
Ankit Chillar: After Effects renders the video frame by frame so if you send a project from AE to Premiere then the sequence would be progressive by design and ca not be changed to interlaced
Jack Savage: why is it not rendering inside of premiere?
Jack Savage: not using premieres render engine
Ankit Chillar: because Premiere will treat the file as a uncompressed media file and render it as it is.
Jack Savage: I would like premiere to operate the same way the AE render engine does, giving me an option to choose the field order.
Ankit Chillar: I am afraid that is not how the application is designed, If you have suggestions for any improvement or feature you can register your suggestions on following link :0186602810
Ankit Chillar: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
Jack Savage: we can force it into interlace by changing the setting in modify, is there a way to make that the default setting when using dynamic link projects?
info: Your chat transcript will be sent to [email protected] at the end of your chat.
Ankit Chillar: No sir, there is no workflow to do that, However a workaround might be possible for that you can post the query on our community forums. The support staff on forums as well as many of our active professional users might help you with the workflow.
Jack Savage: ok thanks
Ankit Chillar: Thank you for contacting Adobe. Good Bye.

I have a 13 inch MacBook Pro (2009) & the "White Screen of Death" is present. Need help?

I have a 13 inch MacBook Pro (2009). Recently I bought an extended hard drive because I had used up the memory on my iDisk. As I was running the Time Machine back up on my new extended drive, the battery on my Pro ran out causing it to shut down. Once I hooked up my Pro to the power cord & logged in, the "White Screen of Death" appeared on the home display. Obviously the battery still works, my phone is able to charge along with the extended drive, I am able to adjust the lighting on my keyboard along with adjusting the brightness on my screen, but the "White Screen" remains. I need help in determining the cause of this issue & the steps I'll need to take in order to resolve this. I love my Pro, all my documents, photos & music are on it & the last thing I want to do is kill my wallet by buying a new Pro. So could someone on here please help me? It would be greatly appreciated & I thank you in advance!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to a Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
