4:2:0 Color Smoothing Filter for HDV? keying HDV

having fun here trying to key a green screen music video shot in HDV..
thought it would be nice to try FCP's plugins on it... including some sort of "pre-blur" but unfortunately i don't see a color smoothing for 4:2:0 color space in which HDV shoots..
any suggestions on what the best way to key this stuff is

Try the G Chroma Sharpen filters in Film Effects (www.nattress.com), which were designed for this. They do 4:2:0 smoothing, and then sharpen the chroma based upon luma detail to get the best edge possible.

Chroma key - color smoothing filter renders vertical lines

several vertical lines appear in render (or QT output), but if I turn the color smoothing filter off they disappear (at the cost of messy chromakey).
These lines do NOT appear when the playback is stopped on (unrendered) timeline or when using play every frame (option + P).
I am using a 720p60 Prores 422 sequence. Interestingly if I output to mpeg2 via Compressor the lines do not appear (but poor HD to SD downscale - hence why I seek QT prores output)
For the moment I turn it off and mess with the chroma keyer controls to clean it up.

Using 4:2:2 smoothing, upstream (above) the keyer, meant to say 720p50 PAL sequence and clips captured via Io Express direct to Prores.

DVCAM to ProRess - Clip Analyze - Color Smoothing

Hello,
A few questions that I'll try to make brief. I'd really appreciate someone experienced giving their outlook.
1 - I've got an old DVCAM project captured and backed up to a hard drive. I'm just pulling the project out again to get it as nice as possible for a master copy and DVD; finish it off as best as possible.
Should I use media manager to recompress to ProRess(HQ) for PAL if I'm going to be doing extensive color grading?
2 - When I look at the clips in the timeline with the analyze tool it says Codec: DV - Pal at Medium Quality. When I check other (my original captured files - before I used media manager on the whole project) those files say Codec: DV - Pal at Most Quality.
Should I be re-creating my project from the original captured files, as the one's my timeline is referencing (after using Media Manager to consolodate the project) say Medium Quality?
I assume, if so, I should do this before the ProRess conversion process, right?
3 - I've heard of using a color smoothing filter before the conversion process to ProRess, but my footage is DVCAM PAL 4:2:0. Does that mean I just skip any color smoothing step, or is there another process for those coming from a 4:2:0 color space?
Thanks so much for any help,

I'll give it one more shot (bring the post to the top of the list) to see if anyone could help with answers to these things.
Anyone?

Looking for a "color pass filter"..Remove all colors but 1

Looking for a "color pass filter"..Remove all colors but 1 or 2.
FCP6 doesn't seem to have one.
Anyone heard of one that works really well & that is fast to use?

Jim,
You are totally missing the point. I am an Adobe Premiere Pro instructor. I have been for 5 years. I added my 1st FCP system 2 weeks ago & am experiencing typical transitional curiosities as all who switch to other platforms & editing apps do.
PP has a color pass filter. I was curious to see if FCP did. That sounds logical to me:) If posting the question about the possibility of there being a color pass plugin bothers you, well , that has to do with you.
If you take a moment to read the prior correspondence, you might see my point.
I think we can bury the hatchet now:)

Color Smoothing 4:1:1 or 4:2:2 (before key in ProRes)

I'm working on some green screen stuff in FCP and I'm wondering what the difference is between the 4:1:1: Color Smoothing tool and the 4:2:2 . Both seem clean when I use the chroma key tool (and I don't see any difference). I'm working with video that was shot in HDV and imported into FCP as ProRes (standard).

So the correct answer is - ProRes 422 is 4:2:2 (at least for compositing purposes). For those interested in learning more, here's the Apple White paper on the subject:
http://images.apple.com/finalcutstudio/resources/white_papers/L342568A_ProRes_WP .pdf
It doesn't matter that the video started life as HDV - the fact that it is encoded as ProRes makes it 4:2:2 from there-on (or until I output it as something else).

Smooth filter..

Hi,
I've built a simple smooth filter Codec.. but I get strange colors near object edges.. can it be somekind of color bleeding? or there is a bug in my code?
Perhaps in the coversion from and to byte?
here is the code thanks

there was a problem in the conversion from byte to int
for this rgb format
i added this 2 functions and now it works..
private final byte convert(float x){
return (byte)x;//((x>127)?(x-255):x);
//return (byte)x;
private final int deconvert(byte x){
return (int)(x & 0xff);
//return x;
and changed the code in this way

How do you filter for photos with develop adjustments?

I wanted to put this information out there, because it was difficult for me to find an answer to the question of "how do you quickly filter for photos that have develop adjustments?"
Some earlier posts in this forum observe that a smart collection has the ability to filter files wherein "has adjustments" is "true." Yes, it can do that. And it can also add in a "date" parameter for more specific targeting. But it cannot simply say, "in the current folder," or "in the selected folder." And frankly, that's the exact situation when I need to filter down to the files I want: I'm in a folder—typically the current folder that I've just imported—and I've done a smattering of develop adjustments. Now, I want to quickly select just those images for export. Can't be done, not with a Smart Collection, anyway.
But Lightroom is nothing if not deep, and if you approach the problem from a filtering standpoint, it will eventually get you there—but the solution is very non-obvious. Expose the filter bar, with your favorite preset: camera info, default columns... it doesn't really matter. Hover over the header bar and to the far right will become visible the "add column" widget. Add a column. From the pop-up menu on the name will come a long list of options, the second-to-last of which is "develop preset." Once that's in place, click on "custom." Save your current settings as a new preset and give it a descriptive name like "adjusted images."
Now, when you're in your current—or any—folder, just click on "metadata" in the filter bar, and your custom preset will be in effect: any images that you've worked on will be selected. It's a fast, one-click selection.
If there's another way of doing this (keep in mind it's for the selected or current folder only), let me know. It's such a seemingly desirable action that I'm kind of astounded there's no built-in or easy or obvious way to do it... or that no photographer has requested it.

I am honored to have a response from Rikk "MVP" Flohr, and I do readily agree that your approach is one way to approach the issue. It puts the relevant images in a discrete area that is easy to access. However (this is where I look a gift horse in the mouth) I find "sorts" a bit underwhelming in comparison to "filtering." Two problems: first, the sort still does not 'clear your deck' of unwanted images. You still have to squint at the badges and carefully select the range at the top (or bottom). Mistakes can be made (and I would be the first to make them). Second, the sort command is "sticky," meaning that folder will always have that sort unless you undo it. In general, I think most photographers want to see a folder's images sorted by capture time, so they can easily glance to the beginning, middle, and end of the shoot. With my method, once you click out of the folder, the filter is taken away and you're back to normal.
I do understand that Lightroom wants me to flag my images with rankings or stars or colors or dancing beavers or what-have-you. But in this particular situation, that's an extra step. If I've applied development adjustments, it's already done. Why shouldn't I be able to choose "Select Developed Photos" from the Edit menu, right under "Select Flagged Photos"?

To retain color space value for Monochrome images during flattening.

In our project, we are extracting image content from PDF file and doing some raster operation by using LeadTool and then flattening the processed image in PDF file.
Input PDf file: One page which has monochrome image
For extracting image content from PDF file, we are using below Acro Plugin API:
AVConversionConvertFromPDFWithHandler
After this, we will perform some raster operations by using LeadTool and then flattening will happen.
While doing flatten we are performing below operations in sequence:
1. Set bitspercomponent =1.
2. Create a new color table using DeviceRGB.
3. Create image by using below Acro Plugin API:
pdeimage = PDEImageCreate(&attrs, sizeof(attrs), &matrix, 0, cols1, NULL, &fil, asstm, NULL, 0);
4. Add image in PDF content.
Now flattening is successful, but monochrome(Original Image format) is changed to RGB. We want to retain the color space(DeviceGrey).
We have tried the below solution to retain the color space:
1. Using the old image's color space value for new image creation. But this gives inverted color(Black to White and vice versa)
Please help us to retain the color space while flattening.

We are using JPG file format.
Please find below the code portions which we used to add image in PDF file,

Choppy clip with color correction filter

I'm working on a video that has multiple clips. The clips that are choppy have a Color Corrector filter on them. The choppy clips stay that way even after exporting, but the rest of the file is fine. All video came from Canon Vixia HF200. I'm thinking I have a memory issue, but I'm hoping it's a user error issue. I'm on a MacBook Pro 2 GHz Intel Core, 2GB RAM. I'm using a Lacie 1TB external drive for the video. Final Cut Express 4.
Any help is appreciated!

Savitzky golay filter for finding second derivative

Hello friends,
I want to find second derivative using Savitzky golay filter for the data as shown in image.
Three different spacings are used.
Region AB and EF= ∆f1
Region BC and DE=∆f2
Region CD=∆f3
Can some one help me to understand to to decide side points and polynomial order for my input data.?
Thanks in advance.

The polynomial order must be at least one larger than the highest derivative. So a third order polynomial is required for a second deriviative. In general it is better to keep the polynomial order as low as possible while getting a good fit to the data.
The number of side points is somewhat arbitrary and depends on how much smoothing is needed. Often some experimentation and judgement is required.
Have you considered resampling the data to create a new dataset with uniform sampling throughout? That might be easier than trying to match derivatives at the transition points.There are several resampling VIs available.
How many data points do you have in each segment?

Somehow I've created 6 color corection tabs for one shot and it's playing havoc - any suggestions? Thx!

Somehow I've created 6 color corection tabs for one shot in FCE, can't seem to delete tham and it's playing havoc - they seem to be overlaying one another giving a dreadful colour balance - any suggestions? Thx!

Either:
Right click on clp in TL and select reove attributes>Filter
or
Open clip in Viewer, Click on Filter tab. In Nemeric view, far left for each filter, select and hit delete.
Good luck.

How to set filter for few Setup Objects on Geneneral Foundation?

Controlling the download of sub-entities:
By default all sub-entities are downloaded. Pass a non-existing value
for the parameter (primary key) of the sub-entity if you don't want to
download a specific sub-entity.
For example, if you don't want to download the values of a value set,
then use following input to FLEX_VALUE attribute while setting filter;
FLEX_VALUE='THIS_IS_A_NON_EXISTING_VALUE_I_DONT_WANT_TO_DOWNLOAD_VALUES'
VALUE_SET
Notes:
- To download '$FLEX$.%' value sets pass '$FLEX$.%' argument.
- Upload API automatically submits the hierarchy compiler request
- FLEX_VALUE_SET_NAME is a required argument for download.
You can find the following parameters in Set Filter screen of Value Set Values.
VALUE_SET has subenities such as VSET_SECURITY_RULE, VSET_ROLLUP_GROUP and VSET_VALUE.
Setting value for attribute FLEX_VALUE_SET_NAME downloads all the subentities. If you want
to restrict the subentities, set appropriate filter at VSET_SECURITY_RULE, VSET_ROLLUP_GROUP
and VSET_VALUE.
Parameters:
VALUE_SET
| FLEX_VALUE_SET_NAME : Value set name.
|
+-VSET_SECURITY_RULE
| FLEX_VALUE_RULE_NAME : Value set security rule name.
| PARENT_FLEX_VALUE_LOW : Independent value for the dependent value sets.
|
+-VSET_ROLLUP_GROUP
| HIERARCHY_CODE : Hierarchy (rollup group) code.
|
+-VSET_VALUE
PARENT_FLEX_VALUE_LOW : Independent value for the dependent value sets.
FLEX_VALUE : Flexfield segment value.
DESC_FLEX
Notes:
- Upload API automatically submits the flexfield compiler request
- Upload API automatically submits the DFV view generator request
- APPLICATION_SHORT_NAME is a required argument for download.
You can find the following parameters in Set Filter screen of Descriptive Flexfields.
DESC_FLEX has subenities such as DFF_REF_FIELD, DFF_CONTEXT and DFF_SEGMENT.
Setting value for attributes DESC_FLEX and DESCRIPTIVE_FLEXFIELD_NAME downloads all the subentities.
If you want to restrict the subentities, set appropriate filter at DFF_REF_FIELD, DFF_CONTEXT
and DFF_SEGMENT.
Parameters:
DESC_FLEX
| APPLICATION_SHORT_NAME : Application Short Name.
| DESCRIPTIVE_FLEXFIELD_NAME : Descriptive Flexfield Name.
|
+-DFF_REF_FIELD
| DEFAULT_CONTEXT_FIELD_NAME : BLOCK.FIELD reference field name.
|
+-DFF_CONTEXT
| DESCRIPTIVE_FLEX_CONTEXT_CODE : Context Code
|
+-DFF_SEGMENT
END_USER_COLUMN_NAME : Segment Name
APPLICATION_COLUMN_NAME : Column Name
KEY_FLEX
Notes:
- Upload API automatically submits the flexfield compiler request
- Upload API automatically submits the KFV view generator request
- Upload API automatically submits the structure view generator request
- APPLICATION_SHORT_NAME is a required argument for download.
You can find the following parameters in Set Filter screen of Key Flexfields.
KEY_FLEX has subenities such as DFF_REF_FIELD, DFF_CONTEXT and DFF_SEGMENT.
Setting value for attributes APPLICATION_SHORT_NAME and ID_FLEX_CODE downloads all the subentities.
If you want to restrict the subentities, set appropriate filter at KFF_FLEX_QUAL, KFF_SEGMENT_QUAL,
,KFF_STRUCTURE,KFF_WF_PROCESS,KFF_SH_ALIAS,KFF_CVR_RULE and KFF_SEGMENT.
Parameters:
KEY_FLEX
| APPLICATION_SHORT_NAME : Application Short Name.

+-KFF_CVR_RULE
| FLEX_VALIDATION_RULE_NAME : Cross Val. Rule Name.
|
+-KFF_SEGMENT
SEGMENT_NAME : Segment Name
APPLICATION_COLUMN_NAME : Column Name
MENU
You can find the following parameters in Set Filter screen of Menus.
PARENT_MENU_NAME Name of the menu to start downloading at. If this
parameter is specified on its own, that menu and
all its children will be downloaded. If specified
with FUNCTION_NAME and/or SUB_MENU_NAME, then only
the menu entry with that function and/or submenu name
immediately under the PARENT_MENU_NAME will be
downloaded.
FUNCTION_NAME Function name to limit download to. If this parameter
is specified then PARENT_MENU_NAME must also be
specified in order to download menus. Specifies
the function on a menu entry immediately under
PARENT_MENU_NAME which will be downloaded; all other
menu entries under PARENT_MENU_NAME will not be
downloaded.
SUB_MENU_NAME Sub Menu name to limit download to. If this parameter
is specified then PARENT_MENU_NAME must also be
specified in order to download menus. Specifies
the Sub Menu on a menu entry immediately under
PARENT_MENU_NAME which will be downloaded (along with
all its children); all other menu entries under
PARENT_MENU_NAME will not be downloaded.
MENU_APP_SHORT_NAME Application short name of Menu. The menu on the resp
for this application will be downloaded. If you

Interactive report filter for date not working correctly

Hi,
I am having an interactive report. I tried to give a filter for a column(created_on) as created on>29-oct-2009 17:17
but i am getting the row containing created on as *29-oct-2009 17:17* in the report result. How can i correct this
problem
Thanks,
TJ

Hi,
I think it is because seconds.
So it is 29-oct-2009 17:17:00 and your record is e.g. 29-oct-2009 17:17:02
br, Jari
Edit
You can use trunc function in your select so that it round date to minutes
TRUNC(created_on,'MI') AS created_onBr, Jari

Set filter for only one column in tableview

Hi
i am using in MVC a htmlb:tableview with filter in only one column of 8.
This is all working fine, except that the user can enter a searchsting in the filterfield for all columns, but in handle_event (of the controller) ; i only react to a text in the filterfield of column 4 and ignore all other filtertext , which were maybe entered in the other columns.
My question:
how can i enter the filter only for one column, in a way that the user cannot enter any text in the filterfield of the other columns, only in column 4 ?
my view:
<htmlb:tableView id             = "requirements"
                 table          = "//model/pdst_reqs"
                 filter         = "APPLICATION"
                 keyColumn       = "EXTID"
                 iterator        = "<%=model%>"
                 footerVisible   = "FALSE"
                 encode          = "TRUE"
                 visibleRowCount = "<%=model->rowcount%>"
                 width           = "100%"/>
Best Regards
Britta

You can disbale the Filter for the particular column by setting the DISABLE_FILTER in the Iterator method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS. Here is the sample code
method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS .
CLEAR p_column_definitions.
CLEAR p_overwrites.
data tv_column TYPE TABLEVIEWCONTROL.
tv_column-COLUMNNAME          = 'FLDATE'.
tv_column-SORT                = 'X'.
tv_column-EDIT                = 'X'.
tv_column-ONCELLCLICK         = 'MyCellClick1'.
tv_column-title               = 'Date '.
APPEND tv_column TO p_column_definitions.
CLEAR tv_column.
tv_column-COLUMNNAME          = 'PRICE'.
tv_column-horizontalAlignment = 'right'.
tv_column-verticalAlignment   = 'middle'.
tv_column-ONCELLCLICK         = 'MyCellClick2'.
tv_column-title               = 'Currency'.
tv_column-EDIT                = 'X'.
tv_column-DISABLE_FILTER      = 'X'.    " <-------Like this
APPEND tv_column TO p_column_definitions.
endmethod.
Hope this will solve your problem.
