How to Crop with AviSynth

Hello, brothers..!
I have been studying and following Bellune's incredible tutorials as I try to turn my HD video into a high quality SD production. So far, the tutorial is amazing, and I couldn't live without it.
I'm using AviSynth scripts through VirtualDub, and it is fantastic. The problem that I need help with is this (and by 'need help' with, I mean I'm about to pull my hair out from all the scouring of 9 year old posts on Doom9's forum! You can post there until after 5 days of registration, so I can't ask them....):
Problem: I need to cut 150 pixels from the left side, and right side of my clip.
I tried adding this to the script:
Crop(150,0,-150,0)
This seems to cut about 180 off the right and left, and then 90 off the top and bottom! NO IDEA why it's doing that.
My overall goal is this:
I exported my 34 minute video into 1920x1080 .AVI (a 9.5 hour job... the resulting file was 75GB).
Then I ran it through an AviSynth script of: hd2sd(OutputColorSpace="YUY2")
This gave me a VERY NICE quality 720x480 file, HOWEVER, I forgot to account for the change in aspect ratio, so the 720x480 file was squeezed narrow. But If I cut 150px off the right and left before running hd2sd(OutputColorSpace="YUY2"), it should be perfect.
And of course, my video just happens to be PERFECTLY able to lose those 150px off of each side (safe margins for me, as the focal point of the video never changes).
Thank you guys, so much.

nooo, dont be shamed.. he meant the opposite.. that its ok to post stuff here about your problem... is OK..and good.
my suggestion about posting in your version area was just a " traffic " thing... like, more people check out those areas to help people with stuff etc etc.
maybe im wrong though, who knows.. i dont see the stats on site traffic...like jeff does
all is well...
sounds like you have to go from square pixel original to wider than a PAR of 1 (square) to something like 1 point something..cause SD is not square.
and good luck
and thanks jeff for heads up re: not just chit chat and misc stuff in lounge

How to crop without changing aspect ratio/Crop mode

Is there a way to crop in Lightroom without changing the aspect ratio? That is my first question.
My second question, is it better to use APS-C crop mode on my full frame Sony A7R if I know at the focal length I'm gonna crop, or just take it full frame and crop in the software? Are there disadvantages to this when it comes to uses flash's etch?
Third, Currently I do not have a portrait lens as the Sony A7R is new and does not have many lenses out yet. Until the 90mm lens comes out I was thinking I could use the Zeiss 55mm 1.8 in Crop mode for a portrait lens. That would make it around 88mm would it compress the background nicely the way an 85mm lens normally does for portraits?

This is what I usually do, now I know for sure my aspect ratio has been locked. As far as shooting in crop mode though, what I meant about that is this; For portraits, if you take a 55mm and shoot a portrait with it, the background doesn't look that compressed, which I like. Even if it's at a good F stop. It'll be out of focus, but not "compressed" And seems to show more flaws in the person. This is why with my Canon I always used my 85mm or my 100mm. I know some who will only use a 200mm due to this type of compression that happens at longer focal lengths.
If I was to shoot in crop mode, making it 88mm, would it give me that affect? The compressed look I get from a 85mm? Or would it simply just crop it like I do in post and not really make a difference.
Sony has yet to come out with a portrait lens and I need one bad, I've been offered little jobs here and there and can't take them because I don't want to disappoint them. I'm waiting for their 90mm, because that is close the 100mm and 85mm I shot with on the 5D for portraits.
Not to same the subject here but, 'Benjamin Root Photography,' has been a great help to me on this forum. I also torn between getting the 16-35mm F/4, or the new 24mm F1.4 prime, for wide landscape shots, because landscape and hiking is where I do most of my photography.
I don't plan on actually shooting a landscape at 1.4, but if it's 1.4 that means if I stop it down to F 8 on a landscape it'll be tact sharp. But it is not a Zeiss and is only going to cost 500. On the other hand, there is the 16-35mm, still I'd shoot around F 8 or even higher for landscape, the problem is, if it's F/4 won't that mean it'll have to stop down much further than the 24mm to get a sharper picture?
I don't guess I can go telephoto, like anything over 100mm because I have the A7R. People say over 100 mm it has shutter vibration, so at 200 or 300 I wouldn't buy until the A7R ii comes out. I'm not willing to get the regular A7 ii because I really like the advantage of having all those megapixels for cropping purposes, and it just plain looks better. Which is why I took my Sony A7 back for the A7R. Everyone was saying the photo's were more impressive than the 5D Mark iii's with the Zeiss 55 1.8 vs 5D with 50 1.4L. That wasn't really the case with the A7, but when I got the A7R I seen a HUGE difference in dynamic range.
I've heard the A7 is better at focusing than the A7R, but since I switched to the A7R I have noticed literally no difference. But I don't shoot fast moving subjects.
With both cameras I notice the face detection and EYE AF is hard to get to work properly. If I let it auto focus fully It'll focus on the wrong thing a lot of times even though the green boxes say the right thing.
So, I have been putting it on a single point, keeping it at the center, focusing on the eye, and then recomposing. That's mostly how I did with the 5D anyway. I never allowed it to choose focus points for me either.

New filters - how to crop and level?

I can see how to crop, using the motion filter, or to use one of the filters to mask off a certain portion of a clip. And I see where you can use the motion filter to rotate a clip a bit in order to correct for tripod tilt.
But I don't know how to use them together to get the result I want, which is a cropped clip with straight edges with a slightly rotated clip inside the straight edges. What I get is a tilted, cropped clip, the sort of thing you routinely do for a still photo in iPhoto.
MikeR

You don't want to crop. You need to scale up. The more you rotate the more you'll have to scale up the image.

Pixel Dimensions after Cropping with "Use Photo Ratio"

Why don't Pixel Dimensions (and Document Size) change for Image Size after cropping with "Use Photo Ratio" like it does after cropping with "No Restriction"? Using Photoshop Elements 10 and Crop Tool defaults.

Thank you all. I think I figured out how to crop using "Use Photo Ratio"
with Crop tool so that I can ensure that my photos are cropped only
proportionately and PSE 10 doesn't upsample pixels:
1) Select Crop tool.
2) Set "Use Photo Ratio" in Aspect Ratio setting in Options bar if not
already set.
3) Make crop selection as usual but don't complete (commit) crop. Will
only be able to crop proportionately.
4) When ready to complete crop, change Aspect Ratio setting to "No
Restriction" which blanks out width, height and resolution setting.
5) Complete (commit) crop as usual.
Photo will be cropped proportionately, width and height will change
automatically to cropped size and pixels will not be upsampled avoiding
lose of detail, that is, PSE will behave as though No Restriction had been
specified from the outset. Blanking width and height before making crop
selection forces either Custom or No Restriction setting which means that
PSE will let me make non-proportional crop.
PS. IMHO I think making "Use Photo Ratio" force upsampling is NOT a good
"design feature" when you are not warned about it and are not given a
choice to not make it upsample.

How to crop a QuickTime movie to delete black top and bottom areas?

How to crop a QuickTime movie? I mean, a ".mov" movie that shows a black area on top and bottom, which I want to delete.
I have tried with iMovie 8.0.5, yet its "Window - Cropping..." to fit, crop and Ken burns does not allow to select the area that I want, which is extra wide.
Thanks.

How to crop a QuickTime movie? I mean, a ".mov" movie that shows a black area on top and bottom, which I want to delete.
Basically, you have two options. 1) You can use an application like MPEG Streamclip (free) which allows you to reset the top/bottom/left/right screen edges (i.e., crop the active viewing area) and then re-compress the remaining content as a new file (as recommended by QTKirk) or 2) if you have QT Pro, you can simply "mask" the player display which crops the display screen to the desired mask dimension and location within the original area. The advantage of the latter work flow is not having to re-compress the file which can be very time consuming. Since the latter method may seem confusing to some, I have prepared a "quickie" tutorial which may be able to "talk" you through the process:

How to Crop an .AVI media in PP CS4 if possible at all.

Yes I'd like to know how to crop an AVI clip" I googled the question and got a lot of photoshop answers instead. What I wanted to do is, using an original clip get 2 short portions of it. that is of two different people jumping out of a plane and have them both spinning inversely 360 degree to the length of a song. I did it but was annoyed with the black edges on either side of the clips, especially interfering with the spinning of each clips (BTW I did export these two short clips after fitting them to the frame in a new sequence but the result is still the same, I hoped the new avi would not have the black edges, but it did not work!) I even would have preferred my two clips to be square for better visual balance but was unable to do this either. This may be a kind of picture in picture or in this case two pics in one. Thank you in advance for any tips

In the Effects Panel (not the Effects Control Panel), there is a little query box. Just type "crop," and it would have popped up - just do not forget to clear that query box, of you will not see your other Effects.
As for a Google search, I would have done advanced, with the string "Adobe Premiere Pro" and then the word "crop" and "effect" above.
THIS is the second hit, with about the same, but for CS3, that I got. Cropping is more commonly used in still Image editing, such as with PS, so most hits on "crop" will probably throws 1000's of PS references. By putting in that string, where all words are kept together and in order, we eliminated nearly all of those.
Good luck,

How to work with 360 video?

I am new to AE and am trying to work with a 360 equirectangular video I shot with a Freedom 360 and 6 go pros.
Are there any tutorials on how to work with 360 spherical videos? Do I need to download additional plugins?
Thank you,
Phil

Phil,
Of course, the image needs to be big for this, but the plugin you would use is CC Sphere.
Drop your movie into a composition and apply CC Sphere to the video.
Then set the Render option in the effect to "Inside".
Under Shading set Ambient to 100% and Diffuse to 0%.
Then scale inside the effect until the image fills the screen.
Then you'll be able to use the Rotate Y controls in CC Sphere to spin around inside your video!
You can also add Optics Compensation and Reverse the Lens Distortion to straighten out your image.
Let me know if you have any questions!

I am having much trouble with the new reminders in IOS7 and how it interacts with Outlook Exchange. Many features lost in the new version.

When I downloaded IOS7, I found that the reminders/task app and how it interacts with Outlook Exchange is much more difficult to use. Some of the issues that I am having are...
1. Trying to edit my task on my phone is not possible, if the notes are lengthy. When you click on the text to edit data near the top, it will scroll to the bottom and not allow you to edit the text because you cant see it.
2. Now all of my task are in one long list. I can not move from day to day like we could in previous version IOS6
3. When I do edit a short task reminder and click done, it crashes and completly goes away. It does save the edit though
4. You can only add task at the bottom of each days reminders. This is very inconvient and much more difficult than IOS6
5. There is a major delay or latency when interacting inside of reminders in this version. Much more than IOS6. It is very unstable and quirky.
I have never seen Apple take a step back with a product until now. I am a huge Apple fan and always will be, so I am hoping they make enhancements to fix these issue. It is a big time prodcutivity killer.
Thanks for any and all help you can give.

Some power supplies or designed so that if there is a short or overload they shut them selfs off and some will not turn back on. Some have a relay that will click back on and work, some you have to cycle the power switch. Those that won't come back on will have to be replaced. I'm not saying that yours is that type as I have no way of telling. But if you have a friend who will loan you a good power supply you might try it. As someone else said just turning off the power will not darn all the power from some motherboards. To test this turn off your power supply than turn on the computer with the start botton. Mine will flash the lights and fans will start to spin than die. So every time you turn off computer to work on it. After turning off PSU hit the start botton to drian any power left in it before working on it. Also do this after unplugging it just to make sure.

How to deal with deadlock on wwv_flow_data table when http server times out

There are some threads about a deadlock on the wwv_flow_data table. None of them contain a real explanation for this behaviour. In my case I will try to explain what I think is happening. Maybe it helps somebody who is hitting the same matter.
In my case with APEX 3.2.1 I am navigating from one page to another. Doing this APEX will lock the table wwv_flow_data. As soon as the other page is shown the lock will be released. But now this other page contains a bad performing query (standaard report region). After 5 minutes the http server (modplsql) will time out and present the message "No response from the application server" on the screen. In the meanwhile the query is still running on the database server and the lock stays on the wwv_flow_data table.
Normal user behaviour will be that the user will use the back button to return to the previous page and tries it again to navigate to the other page or
the user will try to refresh the page with the bad performing query.
And voila now you will have a deadlock on the wwv_flow_data table since a second session is trying to do the same thing while the first hasn't finished yet.
How to deal with it?
First of all. Have a good look at the bad performing query. Maybe you can improve it that it will succeed before the http server will timeout.
In my case the 11gr1 optimizer couldn't handle a subquery factoring clause in the best way. After changing it back to a classical inline query the problem was solved.
Secondly you could increase the timeout parameter of the http server. Although this not the best way.
Maybe it would better if APEX in a next version would release the lock on the table wwv_flow_date earlier or do a rollback just before the moment that the http server is timing out.

Mathieu Meeuwissen

Hello Shmoove,
I saw your reply here and you probably understand the problems the HTTP 100 response may cause.
I am trying to send image that was taken by getSnapshot. The problem is that the server respond with this HTTP 100 message.
I suspect that the reason that my server doesn't recognize the file that I'm sending from J2me is that the "server to client" response to the 100 message comes after the second message of (see what the TCPIP viewer shows down here):

How to sync with two computers not at the same time, I'm registerd with one computer

How to sync with two computers (not at the same time), I'm registered with one computer and am trying to connect with second computer with same iPhone. To sync the first time with the second PC "Firefox Sync Option tells me Create New account or Connect, when I connect it gives me a Passcode and on iPhone it also gives me a Passcode, than how do I connect? Both the iPhone and PC gives me a Passcode and have now idea what to do with them.
Where do I find my Sync Key ? so I can install manually if it works ?

Use the Sync Key ''(Recovery Key)'' from the PC that you used to initially setup your Firefox Sync service, when setting up that 2nd PC with Sync. You need to use '''Add a device''' to setup the 2nd and subsequent devices on a Sync account. <br />

How to deal with OpenCL grey out issue.

First off, I'm not native english speaker.
I have Nvidia GeForce 550 Ti video card, and its support OpenCL v1.1.
I'm also face a "random" OpenCL grey out issue like other people here, but I found the "issue" and how to deal with.
open a command windows (using WinKey + R, and type cmd <enter>)
type "cd C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)" <enter>
type "sniffer_gpu" <enter> -->> to check your GPU has OpenCL in Photoshop?
When GPU is in power-saving mode (core running in 51Mhz, using MSI Afterburner monitor), I running sniffer_gpu, got this report
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>sniffer_gpu
Device: 0000000000328D68 has video RAM(MB): 1023

Renderer string: GeForce GTX 550 Ti/PCIe/SSE2

Then, I switch GPU back to normal status (core running at 900Mhz)

OpenGL ok
OpenCL ok, version=1.1 CUDA 4.2.1
Return code: 3
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>
OpenCL support !!
Nowadays, most of new GPUs were support power-saving, but when sniffer_gpu running at GPU power-saving state, the OpenCL computing report maybe "time-out", cause the detector "guess" the GPU does not support OpenCL. This is why many people says "OpenCL" sometimes work, sometimes grey-out.
I hope this bug can be fixed, or at least people can understand how to "enable OpenCL everytime when you launch photoshop".
Bye.

How to deal with "Error 1001. The specified service already exists" when install a service using installer package?

Hi everybody,
I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
Setup Project to install it.
Here is what I did for the "Class Library":
1. Finish the program.cs, Service.cs
2. Add Installer
3. Change the serviceInstaller so that "StartType" to be Aotumatic
4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
5.
6. Click in F5 (Start Debugging)
Here is what I did for the Setup Project:
1. Add the exe file built from the "Class Library" project to the Application Folder
2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
3. Change the property of the project so that "RemovePreviousVersion" to be true
4. Click on F6(Build Solution)
Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
1. After unstall, the registry was not cleaned up about the installed program
2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
My questions are:
1. How to cleanup the registry when uninstall a program?
2. How to deal with the "Error 1001. The specified service already exists"?
3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
Thanks a lot!

Hi Simon, not a problem!
I spent some more time on this and here are few more notes:
it is called Major Upgrade, when you are installing new version of the product upon a previous one and
MSI supports 2 strategies:
Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
installed files)
Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
will be reverted to the previous state and it'll be still functional.
Let's consider both strategies:
Consider you have installed product_v1.msi and you want to install product_v2.msi.
Strategy 1
1. MSI engine copies files from Product_v1 directory to TEMP directory
2. MSI engine merges files based on the assembly version (between v1 and v2)
3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
Strategy 2
1. MSI engine tottaly removes all files from v1.
2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts allready worked out and MSI doesn't have files to revert machine back
I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
here. So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
AND, you got "Error 1001. The specified service already exists"
because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
installation and they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
and delete), like this:
*clip*clip*clip*
' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
' Update the Service Entry to stop and delete service while uninstalling
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
' Update the Service Entry to stop and delete service while installing
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
*clip*clip*clip*
We can uninstall service first by following Strategy 2, but then we lose transactional support.
So, Simon did I encourage you to change your code a bit?:)
And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
Hope it will help to everybody!

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map
