Timecode problems when logging

‘display the footage in source framerate’

I’m really not sure what you mean…

You say you’ve got drop frame 24p and 24pa footage. That might be where the problem lies in it’s difference of 29.97 with pulldown based Progressive and actual 24 frame per second.

The source frame rate is…what and how are you altering it to get this different result?

“‘display the footage in source framerate’

It’s an option under Edit:Preferences:Media
Sometimes Premiere will capture according to the video in/out, which is usually off by a few frames or a few seconds. When I ‘display the footage in source framerate,’ I can see how off the video in/out is from the media start/end and log in/out.

I have this problem with both 24p and 24pa footage, thought there is no mixing of the two on tape or logs.

thanks Jon

Hi Erik,

I’ve done some research specifically on your camera DVX100 and the 24p 24pA phenomenon. As I mentioned earlier, the “problem” is directly related to the footage not actually being 24P (like film really is) it is ingested at that rate but actually recorded to the tape inside a 29.97fps interlaced format.

There is nothing wrong with the timecodes, it’s showing you what the real “hidden” timcode is on the tape in 29.97fps. When you work in a 24p or 24pA project it does the 23.976 rate for you, incase you are working with real 24P film based footage, but the option you are using will show you what is really happening with the tape’s TC reference to actually capture the footage again in a batch, etc.

Check this link by Adobe.

Do some quick tests to edit and offline some footage and batch capture it. I’m sure it will come in properly.

– Cheers, Jon

do you capture with pro vtr?

if not, try this – could help

Thanks Jon and Federic,

I’ve done tests logging 24p and 24pa footage into 24p and 29.97 projects on pro and non-pro decks. You can definitely see the difference in TC.

The problem I run into is that no matter the footage or the project, I still have problems batch capturing. If a clip is short, there isn’t much problems. But if the clip is long, or I capture a series of clips, I get the wrong footage.

Could you specify some tests that would expose this 24p 24pa problem?

Thanks

But if the clip is long, or I capture a series of clips, I get the wrong footage.

That would suggest the tape TC maybe broken or the wrong tape is in the deck. I’m sure you’ve got it all correct tho…

How wrong is the footage? Like frames off or the whole clip?

I’ll try to run a test or two…

How wrong is the footage? Like frames off or the whole clip?

The clip length will be correct, but it the in/out will be offset.
EX
Let’s say the first clip is 15 frames later in in/out. Not that bad if you’ve given some handle cushion. But the next clip will be 30 frames off. The next one, 45 frames off. Also, if the clip is long, the next clip might be 5-10 seconds off.

From what I’ve observed, for each minute of TC, the In/Out will be 2 frames off.
EX
I log
1;00;00 to 2;00;00 with simulated 24p into a 29.97 project, and when I display source TC, the in/out is displayed as 1;00;02 to 2;00;04 – it has a pattern to its offness.

Now, if I log a clip and then “capture in/out” in the capture window, it never misses the clip. ONLY when I log clips does the footage TC get off.

I really appreciate your advice and help Jon.
