Anyone know a good app for doing this? I can do an image overlay in things like Ulead Visual Studio but it is only good for stills and difficult to move around. There must be a simple way as this is done all the time for TV.

Ulead Studio, virtualdub, Adobe Premiere, and a host of others, allow you to apply filters/overlays, to a range of frames. The problem would be if the images move around alot in the frames.

I guess you read the title of my post but not the actual post.

Personally I get really annoyed when this is done to my films...it distracts more than the nudity of the original...seems to be no longer natural (obviously I´m not referring to porn here). I would suggest if you can´t tolerate the director´s work, then don´t buy or watch such films.

Personally I wouldn't mind watching an elephant pounding your Mom's snatch but sites like Youtube and Myspace won't allow nude vids.

hahahahaha....buuuurrrrnnnnn.

I would like to know how to do that too if anyone knows. But to electro and the rest of you on this post, are any of those programs you mentioned free or cheap and easy to do a single still blur that isn't moving?

=======================

Sorry for the other members who posted such remarks. And I hope that elephant does not go anywhere near your moms snatch.
It could be u wanted to blur out your own private part.

I am currently downloading
ftp://ftp.newtek.com/pub/Aura/Patche..._installer.exe

trial version of Aura Video Paint [2.5]. So if this one does not do it,try googling anything with the word "video paint". good luck

I know this topic is old, but it never got answered well (I think). And there appears to be no good answer out there except for Final Cut users.
I don't know of any retail program that allows is designed to effectively shape or move a blurring instruction over time. After many hours of searching and testing out Virtualdub filters I came up with the following options to get the job done with what is available.

These are static image blocks that I extended out to block images across their movement path in a scene. If anyone knows any other options that might do a better job, I'd love to hear them. But till then, maybe my experience can help a few others out.

How to Blur/Black-out Nudity using Virtualdub

Software used:
Virtualdub (1.7.2)
Filter: logoaway (v4.01)
Filter: logo
Filter: Fill
Avidemux (2.4)
Gimp (2.2)

Alternatives to consider before beginning:
* Clipping out the entire frames with corresponding audio.
* Maintaining audio with a black screen.
* Using the VD Zoom filter to zoom away from undesired images.

I. SET UP YOUR VIDEO SEGMENTS

Create folders: Final-edit, Edit(1-?), Post-edit(1-?)

A. Make an unedited copy (Virtualdub)
- Ctrl+O -> Original.avi
- File -> File Information == Note your codec settings
- Video -> Direct Stream Copy
* Mask the entire segment with edits.
- Save = Edit\Unedited.avi

B. Separate it into work segments (Virtualdub)
- Ctrl+O -> Edit\Unedited.avi
* Mask each segment and save each as Edit\01-(whatever)

Each blur area requires its own segment. Usually these will be defined by shots or revealing/covering movements. Each section with no editing also requires its own segment. For example I will separate the first camera shot as 01 for editing, I won't edit anything on the next camera shot or two and make it 02, I'll edit the next shot as 03 and the next shot as 04, and I'll split the last shot and won't edit the first part 05, but I will edit the middle part 06, but not the last part 07. Also, since the blocks are static, if there is a lot of movement, you may wish to segment the movement multiple times to limit the size of the block.

II. SET UP YOUR BLOCKING FILTER

OPTION 1 Blur rectangles (Virtualdub)
(Blur advantage, limited to rectangle, easy--my pick)

- Ctrl+O -> Edit\01.avi
- Video -> Full Processing Mode
* Video -> Filter -> Add -> logoaway
- Click "Show Preview"
* Define your box location:
- Modify "Logo Border Position" X = Left parameter, Y = Top Parameter
- Modify "Logo Border Size" X = Width, Y = Height

You will want to scroll through the video and adjust your rectangle so that it contains the blocked images as they move through the time frame.

OPTION 2 Solid color rectangles (Virtualdub)
(Traditional, easy)

- Ctrl+O -> 01.avi
- Video -> Full Processing Mode
* Video -> Filter -> Add -> fill
- In the lower left-hand corner select your color (typically black).
* Define your box location:
- Click on the each side of the display pane to drag vertical/horizontal parameters to the box.

You will want to scroll through the video and adjust your rectangle so that it contains the blocked images as they move through the time frame.

OPTION 3 Definable block space = solid or semi-transparent (Virtualdub, Avidemux, GIMP)
(Definable space, no blur available, requires detailed image manipulation)

Create an overlay image template: (Virtualdub or Avidemux)
- Ctrl+O -> 01.avi
- Virtualdub = Video -> Filter -> DeLogo (1.3.2) -> Show preview -> Scroll to image to block -> In the filter dialog, click "Save Frame" in the Analysis row. Cancel the filter.
Avidemux = Scroll to the the image to block. File -> Save -> Save BMP image/Save JPEG image.

If the object moves about you may want to take multiple snapshots.

Use the template to define an overlay image: (GIMP)
- Load your snapshot.
* If you made more than one snapshot. Use "File -> Open as Layer" to stack secondary snap shots on the first. "Ctrl+L" to open the Layer dialog. Reduce the opacity of the secondary layers so that you can see the movement path of the images to block.
* Layer -> New Layer -> Transparency
- Use the lasso to define your object.
- Use the paint bucket to fill it with the color you wish to overlay.

To make the overlay semi-transparent: (GIMP)
- Layer -> Transparency -> Color to Alpha (Click on the bar to select the alpha color)

Use this reference to determine what color value to set to alpha:
Fill color: Alpha color: Transparency:
Dark value - Light value = Very Dark Transparency
Light value - Lighter value = Dark Transparency
Dark value - Darker value = Light Transparency
Light value - Dark value = Very Light Transparency

You may need to go back and change your fill color a few times.
You can also duplicate the transparency layer to darken it further or change the opacity in the Layers dialog to make it more transparent.

Finalizing the overlay image: (GIMP)
- Using the Layers dialog, delete your snapshot layer(s).
- Shift+Ctrl+S -> Select file type (By Extension) -> tga

Overlay the image: (Virtualdub)
- Ctrl+O -> 01.avi
- Video -> Full Processing Mode
* Video -> Filter -> logo
- Logo image -> Select your overlay image
- Check the "Enable per-pixel alpha blending..."
- "Show Preview" to verify it looks like you want it.


***** SAVE THE SEGMENT (Virtualdub)

- Video -> Compression
If you have space, select Uncompressed (we'll compress later).
If you don't have space, select and configure the codec to the original file's settings.

- Audio -> No audio (we'll add it in at the end)

- Save all the modified segments with the same name in \Post-edit\ Folder.


III. COMBINING SEGMENTS

Combining Video (Virtualdub)
- Once you have all the segments completed, move the unmodified segments into \Post-edit\ Folder.
- Ctrl+O -> Post-edit\01.avi
- File -> Append Avi segment -> Post-edit\02.avi
- Virtualdub will also automatically add on Post-edit\03-?? as long as there is no interruption in the numbering.
- If you already compressed to save space Video -> Direct Stream Copying
If you had space and it's all uncompressed Video -> Compression = Select and configure the codec according to the original file settings.
- Ctrl+Shift+S -> Final-edit\02.avi (Additional edits will continue in even numbers.)
* If you wish to use this edited portion by itself, skip ahead to follow the Restoring Audio steps using the "Unedited.avi".


IV. PUTTING EVERYTHING BACK TOGETHER

Make pre- and post- sections in a \Final-Edit\ Folder (Virtualdub)

- Video -> Direct Stream Copying
- Ctrl+O -> Original.avi
* Mask the everything before the edit.
- F7 -> Final-edit\01.avi
* Mask the everything after the edit (or before the next edit).
- F7 -> Final-edit\03.avi

If there are multiple edits, the unmodifed intra-sections and final unmodified section will follow using odd numbering.

Combing Final Video (Virtualdub)

- Ctrl+O -> Final-edit\01.avi
* File -> Append Avi segment -> Final-edit\02.avi
- Virtualdub will also automatically add on Final-edit\03-?? as long as there is no interruption in the numbering.
- F7 -> Final-Edit-no-audio.avi

Restoring Audio (Avidemux)
- Make sure Audio drop down box on the left says "Copy"
- Ctrl+O -> Original.avi
- Ctrl+Alt+S -> Original audio.mp3 (or ac3)
- Ctrl+O -> Final-Edit-no-audio.avi
- Audio -> Main Track -> Audio Source -> External MP3 (or AC3)
- External file -> Original audio.mp3 (or ac3)
- Make sure Video drop down box on the left says "Copy"
- Save -> Original Edited.avi

If you are modifying the length of any of the edited portions, you should use "source audio" for pre- post- unedited sections.
Then skip "Combining Final Video" and do the "Restoring Audio" procedure above on each "Unedited.avi" and restore it to each of the finished edited sections.
You can then follow the "Combining Final Video" procedure to finish up.

I've done that effect before in real time with analog video using a video production switcher. Most old school edit suites had them.

reamon

Matermark Master prog suits that purpose. Very simple.
