ShowFrameNumber

Revision as of 06:05, 27 December 2015

Show frame number or time on the screen.

ShowFrameNumber

ShowFrameNumber(clip clip [, bool scroll, int offset, float x, float y, string font, int size, int text_color, int halo_color, float font_width, float font_angle])

Draws text on every frame indicating what frame number AviSynth sees at that point in the script. This is sometimes useful when writing scripts. If you apply additional filters to the clip, they will treat the text on the frame just as they would treat an image, so the numbers may be distorted by the time you see them. Sometimes this is what you want, as it shows frame blending etc.

The frame numbers will be drawn on the left side of the clip for frame-based, top field first material; on the right side for frame-based, bottom field first material and alternating on the left side and right for field-based material, depending whether the field is top or bottom. Much more on the topic of interlaced video on this page: Interlaced Fieldbased.

Due to text rendering, this filter can be slow.

Parameters

clip  clip =

Source clip.

bool  scroll = false

If true, the frame number will be drawn only once on the video and scroll from top to bottom;

If false, it will be drawn on one side, stacked vertically as often as it fits. Default is false.

int  offset = 0

Sets the starting frame number.

int  x,y = 0

Text position. Their interpretation corresponds to Subtitle's align=4 and the special meaning of -1 is not available.

Note that x and y must be used together or not at all; if they are present, the scroll option is ignored.

string  font = "Arial"

Font name. All installed fonts on the current machine are available. Default "Arial"

int  size = 24

Height of the text in pixels. Default 24.

int  text_color = color_yellow

int  halo_color = color_black

Colors for font fill and outline respectively. Default yellow, black.

int  font_width = 0

Set character width in logical units, to the nearest 0.125 unit. See Subtitle for an example. Default=0, use Windows' default width.

float  font_angle = 0.0

Adjust the baseline angle of text in degrees anti-clockwise to the nearest 0.1 degree. Default 0, no rotation.

Examples

Draw the frame number on the left side of the clip, scrolling from top to bottom, starting with "00009":

Mpeg2Source("clip.d2v") # is always top field first, therefore numbers will be on the left
ShowFrameNumber(scroll=true, offset=9, text_color=$ff0000)

ShowSMPTE

ShowSMPTE(clip clip [, float fps, string offset, int offset_f, float x, float y, string font, int size, int text_color, int halo_color, float font_width, float font_angle])

Displays SMPTE-style timecode labels on every current frame. Format is HH:MM:SS:FF (for example "03:52:39:24" = 3 hours, 52 minutes, 39 seconds and 24 frames).

Frame 0 is marked "00:00:00:00", frame 1 is marked "00:00:00:01" and so on - unless an offset is applied.

Due to text rendering, this filter can be slow.

Parameters

clip  clip =

Source clip.

float  fps = (clip.Framerate)

Not required, unless the source clip.Framerate can't be used. Otherwise, the fps argument is required, and must be 24, 25, 30, or 29.97.

string  offset =

Sets the start time. Format is HH:MM:SS:FF (for example "03:52:39:24" - 3 hours, 52 minutes, 39 seconds and 24 frames).

int  offset_f = 0

Sets the starting frame number; ignored if offset is supplied.

int  x, y = 0

Text position. Their interpretation corresponds to Subtitle's align=2.

string  font = "Arial"

Font name. All installed fonts on the current machine are available. Default "Arial"

int  size = 24

Height of the text in pixels. Default 24.

int  text_color = color_yellow

int  halo_color = color_black

Colors for font fill and outline respectively. Default yellow, black.

int  font_width = 0

Set character width in logical units, to the nearest 0.125 unit. See Subtitle for an example. Default 0.

float  font_angle = 0.0

Adjust the baseline angle of text in degrees anti-clockwise to the nearest 0.1 degree. Default 0, no rotation.

Drop-Frame versus Non-Drop-Frame Time Code

00:00:00:00, 00:00:00:01, 00:00:00:02, ..., 
00:00:59:29, 00:01:00:02, 00:01:00:03, 
00:01:59:29, 00:02:00:02, 00:02:00:03, ..., 
00:08:59:29, 00:09:00:02, 00:09:00:03, ..., 
00:09:59:29, 00:10:00:00, 00:10:00:01, etc 

Examples

ShowSMPTE(offset="00:00:59:29", x=360, y=576, font="georgia", size=24, text_color=$ff0000)

fontheight=32

##bottom center
ShowSMPTE(size=fontheight)

##top center
ShowSMPTE(size=fontheight, y=(fontheight))

##top left
ShowSMPTE(size=fontheight, x=(fontheight*3), y=(fontheight))

##top right
ShowSMPTE(size=fontheight, x=(Width-fontheight*3), y=(fontheight))

ShowTime

ShowTime(clip clip [int offset_f, float x, float y, string font, int size, int text_color, int halo_color, float font_width, float font_angle])

Displays time for the current frame. Format is HH:MM:SS.DDD (for example "03:52:39.800" = 3 hours, 52 minutes, 39 seconds and 800 milliseconds).

Parameters

clip  clip =

Source clip.

int  offset_f = 0

Sets the starting frame number. Displayed time will be increased by offset_f/clip.FrameRate seconds.

int  x, y = 0

Text position. Their interpretation corresponds to Subtitle's align=2.

string  font = "Arial"

Font name. All installed fonts on the current machine are available. Default "Arial"

int  size = 24

Height of the text in pixels. Default 24.

int  text_color = color_yellow

int  halo_color = color_black

Colors for font fill and outline respectively. Default yellow, black.

int  font_width = 0

Set character width in logical units, to the nearest 0.125 unit. See Subtitle for an example. Default 0.

float  font_angle = 0.0

Adjust the baseline angle of text in degrees anti-clockwise to the nearest 0.1 degree. Default 0, no rotation.
