HDVInfo v0.93

Link

This FILTER grabs the timestamp and recording date info out of a M2T-D2V file. You can specify the time/date as an expression which is then subtitled on the video clip. It reads also for HDV camcorder setting during capture - aperture, shutter speed, gain.
HDVInfo use .d2v files created by DGIndex.

Known supported HDV camcorders:
Sony HDR-HC3, HDR-HC1, HVR-A1, HDR-FX1, HVR-Z1

Usage for HDV:

file="c:\clip.d2v"  # so you don't need to type the filename twice

MPEGsource(file) #open the video content
HDVInfo(file) # reads the recording timestamp

Version changes:
Version 0.93 - 09.09.2006
- removed DVInfo code till license clarification
Version 0.92 - 22.04.2006
- fixed bug with Daylight Saving Time
Version 0.91 - 22.04.2006
- fixed bug with local time conversion

Limitation to solve for version 1.0:
- only first file is read from d2v file (so there is a need to create separate d2v file for every m2t file)
- timestamp accuracy is 2-3 frames, so there is a need to add scene change detection to overcome this limitation

Syntax:
HDVInfo(filename, output, x, y, font, size, text_color, halo_color,
rec_format, tc_format, show_error, threshold, autoframes, autodelay, align,
data_code, correct)

filename - name of the input file, it can be .avi or .d2v file extension
x - x position within frame
y - y position within frame
font - font name (defult "Arial")
size - size of the text (default 18)
text_color - color of the text in hexadecimal 0xRGB, where R,G,B is from 00 to ff (default 0xe0e0e0 - gray)
halo_color - color of the halo around text in hexadecimal 0xRGB, where R,G,B is from 00 to ff (default 0x000000 - black)
rec_format - format of the display text - look below (default "%#x, %X")
tc_format - time code format, not supported for HDV now
[b]show_error - indicates whether to display error messages (default true)
threshold - With "threshold">0 the output is switched on if there is a difference of the recording date between
current and last frame which is bigger than "threshold" seconds (default 0)
autoframes - number of frames to display text in auto mode (for threshold > 0)
autodelay - number of frames in auto mode after which text will be displayed (for threshold > 0)
align - alignment of the text (default 3):
1 - left-bottom
2 - center-bottom
3 - right-bottom
4 - left-baseline
5 - center-baseline
6 - right-baseline
7 - left-top
8 - center-top
9 - right-top
data_code - if true, then info about aperture, shutter and gain is added to timestamp
correct - correction of the timestamp in seconds
output - variable to which output timestamp (default "rec_time")

Set Avisynth variables:
current_frame - frame number
rec_time - string of time and date
tc_time - string of timecode (only DV)
aperture - camcorder setting aperture in F stops (only HDV)
gain - camcorder setting gain in dB (only HDV)
shutter - camcorder setting shutter - denominater, eg. for 1/100 the value is 100 (only HDV)


Formats for "rec_format" parameter:
%a Abbreviated weekday name
%A Full weekday name
%b Abbreviated month name
%B Full month name
%c Date and time representation appropriate for locale
%d Day of month as decimal number (01 ? 31)
%H Hour in 24-hour format (00 ? 23)
%I Hour in 12-hour format (01 ? 12)
%j Day of year as decimal number (001 ? 366)
%m Month as decimal number (01 ? 12)
%M Minute as decimal number (00 ? 59)
%p Current locale?s A.M./P.M. indicator for 12-hour clock
%S Second as decimal number (00 ? 59)
%U Week of year as decimal number, with Sunday as first day of week (00 ? 53)
%w Weekday as decimal number (0 ? 6; Sunday is 0)
%W Week of year as decimal number, with Monday as first day of week (00 ? 53)
%x Date representation for current locale
%X Time representation for current locale
%y Year without century, as decimal number (00 ? 99)
%Y Year with century, as decimal number
%z, %Z Time-zone name or abbreviation; no characters if time zone is unknown
%% Percent sign
The # flag may prefix any formatting code. In that case, the meaning of the format code is changed as follows:
%#a, %#A, %#b, %#B, %#p, %#X, %#z, %#Z, %#% # flag is ignored.
%#c Long date and time representation, appropriate for current locale. For example: ?Tuesday, March 14, 1995, 12:41:29?.
%#x Long date representation, appropriate to current locale. For example: ?Tuesday, March 14, 1995?.
%#d, %#H, %#I, %#j, %#m, %#M, %#S, %#U, %#w, %#W, %#y, %#Y Remove leading zeros (if any).

That's great! I PMed Warp about something like this, but he was not sure how to go about or I think uninterested. I'm glad you did this, thank you very much.

[Backwoods]

How would I go about making "rec_format" blank?

How would I go about making "rec_format" blank?

Backwoods what do you mean by blank? Without stamp? Then rec_format = "" should not display any text on clip.

Version 0.91
Fixed error with UTC time conversion. The date was wrongly changing according to localization (the farther from GMT 0, the more hours were shifted).

Version 0.92
Fixed bug with Daylight Saving Time

[Backwoods]

I'll test your updates tonight or tomorrow. Thanks again.

where is sourcecode of hdvinfo (GPL)?

[paviko]

The target license will be GPL. Currently it's just freeware.

Regards

[Wilbert]

If it is based on DVInfo you will have to make it GPL once you distribute it.

As a separate question, are you going to make you wonderful plugin HdrAgc GPL? (I know you talked about it before and you were not sure about it.)

[paviko]

Hi.
I've removed DVInfo code till license clears up. Reasons are the same as with HDRAGC.
I was sure to release HDRAGC as GPL, but now there is possibility that the code will be used in commercial application, so GPL doesn't fit here. If it won't be used commercially then I'll switch to GPL.

Version 0.93
- removed DVInfo code till license clarification


Thank you

Hi all,

has anyone managed to make this plugin work? I get the following error:

CAVIStreamSynth: System exception - Access Violation at 0x0, reading from 0x0

Apparently other users have had this issue before with other plugins and its related to memory but I haven't found any way to resolve it.

Any ideas?

Many thanks
sp.

Managed to make it work by unintalling avisynth, ffdshow and reinstalling them back.

thanks.

Hi there,
I have a problem with using HDVInfo to implement the timestamp into my video. I captured the video from my sony hdr-hc1 PAl by using HDVSplit 0.77, then ran DGIndex 1.53 to extract the timestamp. When I then insert the timestamp via virtualdub and avisynth it looks like success but damn it... watching the video I realize, the the timestamp is drifting... it is slower than it has to be. It's a difference of about 10%.

Is there anyone able to help me out?

Thank's
Andi
