StDTam jich je celá stránka a navíc si jejich nastavení můžeš definovat sám, takže kombinací přehršel. Myslím, že jsou vyjmenované v Helpu, ale jsem teď na Dialupu, takže nemám čas to hledat...

Using the Procoder Application
Video Filter tab
The Video Filter tab lets you apply filters to your video to help improve image quality of your source files before they are converted. These filters can be previewed in this tab, but are applied when the video is being converted to its new format.

Video filters

601 Correction - Expand Color Space - This video filter expands the RGB range of the video from 16-235 to 0-255. Use this filter to create output for a system that uses the full 0-255 range from input that uses 16-235.
601 Correction - Shrink Color Space - This video filter shrinks the RGB range of the video from 0-255 to 16-235. Use this filter when create output for a system that uses the 16-235 range from input that uses the full 0-255 range.
601 to 709 Color Correction - This filter converts the ITU-R BT 601 SD color range to the ITU-R 709-5 HD color range. Use this filter for exact broadcast color conversion from SD video to HD video.
709 to 601 Color Correction - This filter converts the ITU-R BT 709-5 HD color range to the ITU-R 601 SD color range. Use this filter for exact broadcast color conversion from HD video to SD video.
Adaptive Deinterlace - This video filter combines the fields of an interlaced video source's fields back into frames using special processing to preserve full resolution while guaranteeing smooth motion.
Bitmap Keying - Superimpose a bitmap logo or graphic on the video. This is often used to watermark video so it can be personalized.
Black/White Correction - This filter lets you adjust and control the levels of black and white pixels in your video. By adjusting the sliders, you can specify at which point a pixel will become black and/or white. The higher the setting, the more nearly black pixels will be converted to true black and vice versa. This works best if you are encoding video for the web and need to adjust the black and/or white levels of broadcast video so that they are truly black or white. It's also useful for making white titles on a black background more legible when viewing on a computer monitor.
Blur - This filter blurs the video in a rectangular pattern.
Circular Blur - This filter blurs the video in a circular pattern.
Color Correction - This filter allows you to adjust the brightness, contrast, hue and saturation of your video image.
Color Safe - Some colors that can be displayed on a computer cannot be displayed on television or video output. This filter restricts the colors in the source to only colors that are safe for television and video broadcast.
Crop - Remove unwanted edges on the video with this filter. This is often used for removing any edge blanking or other unwanted video information from the top or bottom of the video frame.
Fade In/Out - This filter applies a fade in and/or out to your video in order to aid the encoding process. You should use this filter if your source video has a lot of fast motion in the first few frames. The fade in gives ProCoder a "running start" so it can encode your video more efficiently.
Gamma Correction - This filter lets you adjust the gamma settings of your video.
Gaussian Blur - This filter applies a Gaussian blur to the video.
Median - This filter is designed to improve picture quality by removing single-pixel defects without affecting the sharpness. This is similar to a despeckle filter.
Video Pulldown - This filter offers conversion without interpolation for progressive-to-interlaced (such as film to video) file conversion. This preserves full spatial image quality and creates target fields that are selected from the nearest temporal source frame. Displaying the resulting file on a progressive display, such as a computer monitor, produces very noticeable interlacing artifacts. However, displaying this on an interlaced display, such as a television, produces very good image quality. This method is generally used when cinematographic footage is encoded to a DVD and played on a TV.
Video Rotate - This filter provides 90-degree rotation and axis-flipping for the video.
Video Sharpen - This filter sharpens the video using the "unshapen mask" technique.
Video Temporal Noise Reducer - This filter removes noise by using temporal noise reduction. Temporal noise reduction is effective for removing analog noise.
Adding a Filter
To add a filter to the Video Filter list:

Simply click the Add button. The Add Filter dialog box appears and gives you several filters to choose from. A brief description of each filter is listed in the yellow Description box below when the filter is highlighted.


In the Add Filter dialog box, choose a filter by double-clicking on it. The filter's name appears in the Filter List and a preview of how it affects your source video appears in the Result window adjacent to the Original window. You can browse the different filter categories on the left and choose filters from the right. Holding down Shift or Control and selecting the desired filters lets you add multiple filters to the Filter list.


Use the sliders to adjust the filter parameters to your desired specifications.

Removing a Filter
To remove a filter from the Filter List:

Highlight the filter in the list

Click the Remove button to remove the filter. If you want to remove all the filters you've applied so far, simply click the Remove All button.


Loading and Saving filters
To save a custom setting for the currently selected filter, click the Save Preset button.
A dialog appears asking you to name and enter a short description of your preset.



Custom presets are stored along with the default presets and can be categorized into folders and subfolders.

To add a customized filter preset, simply click Add and load it the same way you would load a default preset.

To remove a customized filter preset, simply click Add to open the Load Video Filter Preset dialog, click the filter preset you want to remove, then click the Delete Preset button.

Preview Windows

The Original window displays what the original file looks like before filtering.

The Result window displays the original file with the filters applied.

The Plus button enlarges both preview images, and the Minus button makes both preview images smaller. If the preview image is larger than the window, scroll bars appear allowing you to navigate through the entire image. You can also click and drag on the image to navigate through the image.


The Fit to Window button resizes the preview images to fit inside the window's current size. No matter what size the window, this preview mode preserves the aspect ratio assigned to the file. This button is useful if you enlarged or reduced the preview image and want to view the whole image in the window again.


The 1:1 button displays the video at 1-to-1 pixel size. (1 monitor pixel = 1 video pixel)


The Scrubber bar is used to find specific frames in the source video that you want to use so you can see the effect of the filter(s) on the specific frame. You can either click and drag the scrubber or use your keyboard's arrow keys to step through the video's individual frames.



Settings
This section displays the settings for the particular filter you are using. Use the sliders to adjust the degree of modifications for each filter.


Large Preview
Clicking the Large Preview button opens a floating window that allow you to modify the preview size. This is helpful for scrutinizing the finer details of your video. You can use the scrubber bar to find specific points in the video. You can resize the window as needed, and it adjusts the size of the previews proportionally. It also contains the same controls as the video filter tab.


The Orientation button switches the orientation of the preview windows between horizontal and vertical.

BartoJa som chcel skôr vedieť ktorý s tých filtrov sa oplatí používať ale aj tak dík B-)

No jo, jenze nanapsal jsi na co potrebujes filtr 9-) . To je jako kdyby jsi se zeptal jake je nejlepsi auto a nenapises k cemu ho potrebujes. Jestli na machrovani nebo na cihly.
Kdyz Ti odpovim, ze nejlepsi je napr. Circular Blur , tak se v pristim prispevku asi zeptas na co je dobrej.
Nedava to smysl. Zkus se priste vice rozepsat co presne potrebujes. Ale nerozepisuj se jak OdeSakEda, protoze ty prispevky od nej ja zasadne nectu :-E :-E :-E

Tú otázku či sa oplatí používať filtre CPC som sa pýtal preto lebo niekde tu vo fóre som čítal že filtre v ProCoderi sú na :-k a chcel som vedieť či je to tak. Filtre budem potrebovať asi nasledovne odstránenie šumu z videa, odstránenie prekladania atď. Ale ide mi hlavne o to či tie filtre majú požadovanú kvalitu ale bo to radšej robiť v nejakom inom softe. asi tak 9-)

Žádný filtry na odstranění prokládání a šumu nemůžou bejt dobrý už ze zásady věci ...
Když odstraníš šum, tak i zároveň detaily ...
Když odstraníš prokládání, odstraníš polovinu snímků ...
