How to change Datecode in DV AVI

[jaapg]

I recorded some footage while the clock in the cam was wrong, exact one year off.

Is there a tool to adjust the Datacode in the DV AVI file with an offset, just as there are tools to adjust the Exif datetime in .JPG files?

I do not want to 'burn' the date in the frames but only want to update the datecode itself, without modifying the recording.

Before asking I Googled the web, newsgroups and Videohelp and had a look at DVdate.
AFAIK DVdate cannot change the Datecode within the DV file, only rename the file itself.

strip out the date first


add new date

Are you sure you are talking about DVdate by Paul Glagla?
I cannot find "strip" or "add" date options.

ok - maybe not .. i thought it did ......


you strip out date code anyway by restreaming it in vdub ....


you could do it with two cameras though -- just change the date on the recording one .....

This probably won't work - see https://forum.videohelp.com/viewtopic.php?p=1592023#1592023 - unless the recording device can be configured to write new date/time.

How urgent is your need?

If you have Windows XP and an SSE2-capable processor - and you can wait a week or two - we will be adding this function to our Enosoft DV Processor (it's been on the to-do list for a l-o-n-g time).

It is not urgent, just personal recordings form earlier this year, I do have a capable computer. I will wait with patience for the development of the Enosoft DV Processor!

Actually DVdate can modify the datecode inside a DV file, but only by adding or substracting an integer number of hours. It's called "Fix a time difference" in the menu "Convert". This feature is useful if you travel abroad and forget to modify the time of your camcorder, or if there is a change in summer/winter time and you omit to change it in your camcorder.

In the next version of DVdate (to be published before end of october) the integer hour limitation will be removed, and you may correct a datecode by any time difference (even years, seconds etc...)

I did look at the "Convert->Fix a time difference" option but it is not selectable (grey), I looked at the help on http://paul.glagla.free.fr/dvdate_7_en.htm, but this is for version 5 an this option did not exist then.
Option "Inlay" is selectable though and works as expected.

In the next version of DVdate (to be published before end of october) the integer hour limitation will be removed, and you may correct a datecode by any time difference (even years, seconds etc...)

Great! The more choice, the better.

That is a very usefull feature - I did exactly that (record in US something with Romanian timestamp).
Thank you for your free software!

I had a similar issue: I wanted to process DV files (DESHAKE) without changing the date/times. I found that I could save the timestamp info with AVCutty, then, after I processed the DV, I could restore the date/time info, then save all the scenes in the DV.

However:
AVCutty is a little buggy - The latest version (2.4d) sometimes seems to stop saving the video before it's done. The previous version (2.4c) sometimes gives me a weird error message and refuses to save anything.
(Now I use VDub to split up DV, I really don't trust AVC very much anymore)

Anyway it does restore the date/times, and since it's from an ASCII file, you can modify the date/time for each scene. Make sure when you save the timestamp info, that it's a format that it can import.

Perhaps the programs: dvtimeutiliy or dvsubmarker?

Paul Gaggla is your actual version DVDATE released july-2006?
I use your programs cassete and dvdate for my home video.
Thanks

OOPS!
I screwed up! I thought I had put dates on the file that went through the processing, but the filename in the scene list caused the original file to get rendered wilth AVCutty.

So basically we're all back where we started. Is there anyway to get dates/times back into DV files?

It seems like a simple thing to do. Read some form of scenes list, go to the indexed frame in the DV file, and start incrementing the date/time until the frame that the next scene starts on.

I'm a little confused why the Datecode comes up "N/A" and Timecode stays "00.00.00.00" throughout the file. (Panasonic codec). I would have expected the file to have the date and time it was produced by the codec.

I hope this thread still has some life in it.

Sorry for the initial confusion
