Tool to restore timecode information ?

lupus11 · 26th October 2005, 16:18

Does anybody know about a tool to restore timecode information in a
DV avi file. I usually process my DV files in avisynth (deinterlace, various
filtering, color corrections etc). I usually do this in a way that does not
change the length,framerate or the audio part of the clip. I reencode back to DV. After this I use a standard video editing program to set up the scenes,
scene lengths, transitions etc.

The problem is, that the filtered clip does no longer contain any time or
datecode information. These informations are (of course) removed by
the avisynth/reencoding procedure.

What I am looking for is a sort of tool, that gets the timecode info from
the original (camera) clip and inserts (e.g. patches) this information
back in the filtered clip.

I tried to write one myself, based on the information in ffmpeg, however
my video editor program does not recognize the information. Obviously I am
missing somehting.

Any suggestions ?

Thank You

Try DVDATE 5.3.4 ( http://paul.glagla.free.fr/dvdate_en.htm )

Also you can split your "original" DV file into scenes with free scenalyzer ( http://scenalyzer.de/scenalyzer.zip ). Then procces them (joined or not) scene by scene. Then match them the timecode manually with a program called DV Time Changer ( http://video2dv.com/index.php?lang=en&page=dvdtc ).

Thank you for your answers, they pointed me in the right direction.

Actually I am going to use scenalyzer, however I want to do all processing first
(after all it is 5 hours of footage), that's why I need timecode back in my
processed file. Cutting the scenes first and doing the processing afterwards
is way too time consuming for me.
DVDate obisously can't write back date and time info into the avi file (or am
I missing something ?).

DV Time Changer is probably the software to investigate. Unfortunately it is
not open source, however by comparing its input and output it may help to
find out, why my own code is not working.

You can try to contact with Mike Laba (DV Time Changer programmer) to see if he can help you in any way?! (perhaps delivering the source code). This software is freeware.

Good Luck & if you can obtain a software that can 'transfer' the timecode from an DV-AVI to another DV-AVI (with the same frame number, of course) you can share it in this forum!!!

i've already heard from mike on this issue and he says there are no such plans in the near future.
on the other hand, i've received email from basilik at this address:

http://mvideo.ddpp.net/eng/index.htm

basilik says he is working on such an app but has no time for development. i've just emailed him
encouragement to pursue it over his other app since there are already others like it but his
dvtimeutility would be the only one i've seen in months of searching. i'd encourage others with
similar needs to email him as well. i did so through the email address at the bottom of the page
linked above.
