Need help creating a date stamp subtitle

[catback]

Hi,

I own a Sony HDR-CX150 camera that records in the AVCHD H.264 format that I will be authoring to a blu-ray disc. I would like to add a date stamp to the authored video clips. One method is to embed the date onto each frame. However, this would mean the clips would need to be re-encoded which I want to avoid.

The second method is to create a date stamp subtitle file. I haven't been able to find any guides online on how to do this and what software is required. Anyone have experience using this method? Thanks.

Hi,

I also have an AVCHD camera, however mine is a Canon HF100.

Here is what I do. Get the AVC files from the camera (resulting in files with date and time in the filenames like "20110806113021.m2ts")

I load these files in Sony Vegas for authoring. Once authoring is done I export an EDL file in Vegas.

This EDL contains all necessary information for creating a subtitle file (srt format).

I have written a .NET app for processing the EDL file to a SRT subtitle file (including some features to modify the timestamp in case you set it wrong when recording or you forgot to change the time when daylight saaving changed). Also a chapters file is automatically created.

The SRT file you can include in a MKV to have optional subtitles. As an alternative you can use it in TSMuxer and have optional subs when muxing as bluray.

I had also made a tool like this for Pinnacle Studio, but this is an older version.

If you or somebody else is interested in this tool I can post it, including source, but its quick and dirty coding.

It really depends on the authring software and if its possible to get the timestamps from your cut.

I am not sure about your model, but I have Sony HDR-XR500V and it automatically embeds date/time stamp as subtitle track when I record with the camera.
Check your manual.

you can use avchd2srt to generate srt subs containing date/time and GPS info if your camera records it. It's a commandline application, but there are some GUI's later on in the thread
