How to extract datecode from Adobe PP1.5

Amit · 21st September 2005, 03:51

Hi,

Does anyone over here knows how to extract the Datecode information from a Permier Pro 1.5 project. I am willing to look at non-freeware products too, if you know. Any method, automated (Premiere Pro Plugin) or manual (Exporting the final cut with fade, transition, effects etc and then extracting datecode) will work. I need to create selectable subtitles in DVD from this datecode information. I have already looked at http://dve.teletex.ru/en/dvrecdate.shtml and this does not export the subtitles, it burns on the video.

Has someone done anything like this?

Thanks in advance,
-Amit

I started a project with that as one of its aims a couple of years ago.

I started off a writing a specialised media player program which played DV AVIs and displayed all of the metadata (that's the so-called "data code" and information about the aperture, shutter speed and white balance) on a frame by frame basis alongside the video as it was playing.

I had got as far as adding the ability to "burn" the information over the frames themselves. I would have then progressed to outputting files that could be read into a subtitling program but had to shelve it before that.

Not much help to you I'm afraid. At that time there was a few programs emerging which were able to extract the date and time information - perhaps things have progressed more since then.

Note that re-rendered footage does not contain metadata (at least it didn't then) as it is fabricated by the editing program. Only footage which is not re-rendered is passed through with its metadata intact.

afaik after exporting from premiere the datecode info is stripped, so you would either have to do it in premiere via some sort of plugin or before that,

some info is here:

Only in the parts of the project where the footage is being re-rendered by premiere. Unchanged footage is passed through unchanged and so retains all of its metadata.

Re-rendered footage is effectively NEW footage created by premiere so the concept of the original metadata doesn't always make much sense.

Hmm. That's interesting. Do you know of any site that documents this? I'm interested particularly in when premiere sees the need to re-render a clip and how it gives users this feedback.

It rerenders evertime you apply a transformation / effect or anything else that alters the videostream - everything that is more than a simple cut -> fades / wipes / effects. Everything red in the timeline is footage that will be rerendered i.e. decode from the original stream, apply transition / effects -> encode new video with DV compression.
