To apply a filter, click the arrow in the column header, and pick a filter option. The data in this row won't be filtered.ĭon't select the check box if you want Excel for the web to add placeholder headers (that you can rename) above your table data. Select My table has headers to turn the top row of your data into table headers. In the Create Table dialog box, you can choose whether your table has headers. On the Home tab, click Format as Table, and then pick Format as Table. When you put your data in a table, filtering controls are added to the table headers automatically. For example, if the column contains three values stored as number and four as text, the Text Filters command is displayed. If there is a mix of data types, the command that is displayed is the data type that occurs the most. Values returned by a formula have changed and the worksheet has been recalculated.įor best results, do not mix data types, such as text and number, or number and date in the same column, because only one type of filter command is available for each column. When you reapply a filter, different results appear for the following reasons:ĭata has been added, modified, or deleted to the range of cells or table column.
When you hover over the heading of a filtered column, a screen tip displays the filter applied to that column, such as "Equals a red cell color" or "Larger than 150". When you hover over the heading of a column with filtering enabled but not applied, a screen tip displays "(Showing All)".Ī Filter button means that a filter is applied. To determine if a filter is applied, note the icon in the column heading:Ī drop-down arrow means that filtering is enabled but not applied. For example, you can filter by a list of numbers, or a criteria, but not by both you can filter by icon or by a custom filter, but not by both. Each of these filter types is mutually exclusive for each range of cells or column table. filter_complex "overlay='if(gte(t,1), -w+(t-1)*200, NAN)':(main_h-overlay_h)/2" test4.Using AutoFilter, you can create two types of filters: by a list value or by criteria. Once you start getting the hang of this, you can even animate your overlays! ffmpeg -i test.mp4 -i watermark.png \ filter_complex "pad=height=ih+40:color=#71cbf4,overlay=(main_w-overlay_w)/2:main_h-overlay_h" \ If we wanted to add branding or a watermark to the clip but not cover the existing video, we can use the pad filter to add some padding to our clip, and then position our watermark over the padding like so: ffmpeg -i test.mp4 -i watermark2.png \ filter_complex "overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2" test2.mp4 Using these variable we can position the watermark right in the center of the video like so: ffmpeg -i test.mp4 -i watermark.png \
Fortunately, there are variables you can use to better position your watermark depending on the size of the video.
In some cases you might not know the exact dimensions of the videos you’ll be watermarking. We specify a specific position of the overlay in pixels – 10:10 puts the video 10 pixels from the top and 10 pixels from the right. Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so: ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4īasically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.
The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter.
