how to add an offset timecode for a 14.25 fps clip?

[ericg2387310]

I've been given a one-hour surveillance video with no time stamp burned in, and I need to add the correct time code to the final video. The frame rate is 14.25fps. In the Timecode panel, it shows correctly; but if I use the Timecode effect to create a burned-in timecode, that frame rate is not an option. I also don't see an  option for offsetting the start time in the Timecode panel. If the start time should be 8:00PM, and I want to use a 24-hour setting, the timecode read-out should start at 20:00:00:00. It currently starts at 0.

How can I create a burned-in timecode that starts at 20:00:00:00 and runs at 14.25fps?

Many thanks -

I don't think 14.25 FPS is supported.

It works correctly in the Timecode panel, but not in the Effect overlay. I can screen record the Timecode panel, then crop that clip and make an overlay for the video; but I was hoping that I might be able to avoid that.

But is there a way to offset the starting time in the Timecode panel? I didn't see one.

Also - do you, by any chance, know what font the Timecode panel uses for its display? If I have to dummy up the hour, I'll want it to match.

Eric,

The only example online that I could find for a 14.25 frame rate was a video that is variable frame rate. The 14.25 would probably be an average.

Look at the file in Media Info or similar. Is it Variable frame rate? What is the minimum and maximum frame rate?

In the absence of an actual burned in timecode (i.e. not a "code," but the actual time stamp of each frame), I don't think you can find an "accurate" timecode to burn in. Even putting just the minutes/seconds (with no frames/milliseconds) could be inaccurate.

Thanks, Stan. I think you're right on all counts. I've tried a number of approaches, and none give me consistent results. I'm probably going to have to forget about doing this.

What would happen if you put your 14.25 fps clip into a 25 fps sequence and use 25fps timecode?

[ericg2387310]

I tried that. The time code is completely inaccurate. The 59-minute clip appears to start at 11 minutes and end at 36 minutes. I'm moving on.

Try transcoding the orignal clip in Shutter Encoder to get to constant frame rate and then use Metadata & Timecode Burn-in set to Source Timecode.

Another approach is to drop the original clip into a Sequence with a SMPTE compliant time base (like 29.97), and export that to conform the footage to a SMPTE frame rate.  Then use that in place of the orignal clip for the timecode burn-in.

While it's not as convenient as timecode, using "Frames" will place an indelible time stamp on the footage like timecode does - it just doesn't provide an easy way of knowing how much time has passed.

I'll try these approaches. Where will I find Shutter Encoder?

I'll try that - thanks!
