## ShowFrameNumber

`ShowFrameNumber` (clip, bool "scroll", int "offset", int "x", int "y", string "font", int "size", int "text_color", int "halo_color")

`ShowFrameNumber` draws text on every frame indicating what number AviSynth thinks it is. This is sometimes useful when writing scripts. If you apply additional filters to the clip produced by `ShowFrameNumber`, 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.

If scroll (default: false) is set to true the framenumber will be drawn only once on the video and scroll from top to bottom, else it will be drawn on the right side as often as it fits. For top field first material the framenumber will be drawn on the left side of the clip, for bottom field first material on the right side and for field-based material it will be drawn alterning on the left side and right side of the clip (depending whether the field is top or bottom).

Starting from v2.56 other options (offset, x, y, first_frame, last_frame, font, size, text_color, halo_color) are present, see Subtitle for an explanation of these options. offset enables the user to add an offset to the shown framenumber.

## ShowSMPTE

`ShowSMPTE` (clip, float "fps", string "offset", int "offset_f", int "x", int "y", string "font", int "size", int "text_color", int "halo_color")

`ShowSMPTE` is similar to `ShowFrameNumber` but displays SMPTE timecode (hours:minutes:seconds:frame). Starting from v2.53 the fps argument is not required, unless the current fps can't be used. Otherwise, the fps argument is required and must be 24, 25, 30, or 29.97. Starting from v2.56 other options (offset, offset_f, x, y, first_frame, last_frame, font, size, text_color, halo_color) are present, see Subtitle for an explanation of these options. offset enables the user to add an offset to the timecode, while offset_f enables the user to add an offset to the timecode specifying the number of frames (offset takes precedence over offset_f).

Take care: both filters are due to text-drawing quite slow.

drop-frame versus non-drop-frame timecode

If the framerate of the clip is between 29.969 and 29.971 drop-frame timecode is enabled. Originally, when the signal of the TV was black and white, NTSC run at 60 Hz (30 fps). When they added color, they changed it to 59.94 Hz (29.97 fps) due to technical reasons. They run 1000 frames, but count 1001 (they never actually drop a frame, just a frame number). The first two frames are dropped of every minute except the tenth, ie 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 ... Counting the dropped frames implies that 00:10:00:00 in drop-frame matches 00:10:00:00 in real time.

Examples

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

    # will draw the framenumber on the left side of the clip using an offset of 9 frames, scrolling from top to bottom
    Mpeg2Source("clip.d2v") # is always top field first
    ShowFrameNumber(scroll=true, offset=9, text_color=$ff0000)

Changes
