My Sony DCR-SX41 has the wrong time stamp on a video I took back in 2020 and says 2009. Is it possible to change that date to the proper one or is it stuck like that?

From the 'Operating Instructions' manual:
"The recording date and time are not displayed while recording. however, they are recorded automatically onto the tape. To display the
recording date and time, press DATA CODE on the Remote Commander (remote control) during recording."

I use this information in photography, its caled EXIF Data, and basicaly is the internal information stamp in the pic (date, camera type, focus used, expsure range, etc, etc).

EXIF data on each movie clip recorded is stored in the accompanying .THM file which is a small JPEG thumbnail file of the first frame of the movie.

Force open the *.thm file with photoshop (or simply make a backup copy and change the extension to *.jpg) and read the EXIF via Ctrl+Alt+Shift+I.

I know that the video files also keep this information and could be vewer and modificated; try to check this software and apply it: topshareware.com/sony-camera-exif/downloads

Additional details could find in this site: www.exif.org

Just one last personal recommendation: ALLWAYS, ALLWAYS keep some backup copy about your files.

Good luck.

it might just be a missing codec from the player you're using. your options are either to download codec packs or download vlc media player(a player embeded with mostly all codecs) click here to download vlc player. click here for sld codec packs

you need to install drivers Sony DCR-SX41 Camcorder on your pc so that you can transfer video and burn it

Well if you decided to date/time stamp on your films, then that is what it has done for you, just go into setting on menu and turn them off again, that is the default mode.

The time/date is 'stamped' onto the video during recording. The time/date stamp function can be turned on or off in the setup menu. If it was 'on' during recording, it will be displayed when played back. If it was turned off, it will not be seen on the recording.

got the remote that came with the camcorder? Hit data code button onthe remote and your date data should be there! Good luck.

I have the same problem

As we know you should use the profetional movie making software so you will be able to do the stamp of date.
