can you help me please with timing and milleseconds units?

[rama]

Hi
can you help me please with timing and milleseonds units?

1) i would like to have a (a time ) calculator

2) can somebody explain 2 things about premiere pro cc


a) like the screenshot 1
there is
start 00:00:07:01
end 00:00:20:24
duration 00:00:13:24
are seconds , frames or millisencods ?
can i convert easly with a tool ? like a calculator


b)in the second screenshot on the clip
+6:27
and above -6:27
are seconds , frame ....

please help me ?
i got many headaches

thanks mate

You can use MPC-HC and ffdshow's on screen display for accurate info. There's an example here:
https://forum.videohelp.com/threads/367953-How-to-find-out-frame-exposure-time-in-a-var...=1#post2352710

I've never used premier but the time being displayed can't be milliseconds as that requires three digits. Maybe it rounds it for the tooltip, but if that's the case it seems a bit dumb.

I think ffdshow does the same as AVIsynth and starts the frame count at zero, so the first frame is frame zero. I can't remember for sure if it does but it might be worth keeping in mind as no doubt some programs start the frame count at 1.

1st part - there are plenty of good TimeCode calculators out there. I have a nice freeware one on my Android phone, as well as one or more on my Windows PC. Just do a google search on "timecode calculator freeware" and then take your pick.

Understand the nomenclature - Timecode as it relates to video (which is fundamentally based on frames) shows as HH:MM:SS:FF, where Hours-Minutes-Seconds all have their usual range and Frames has a range that is based on which framerate is being used. Note that you may also see HH:MM:SS;FF (notice the semi-colon instead of the colon). This designates the use of NTSC (29.97) Drop-Frame time. You remember this by the fact that the semi-colon drops down.

In that 1st picture, unless we're missing some bit of vital info, it ought to have said duration 00:00:13:23, not 00:00:13:24. Since those have all colons, you know it is talking about Frame-based timecode.

Time which DOESN'T need to be measured in frames, such as with many kinds of audio, would be designated HH:MM:SS.xxx where xxx is the fractional portion of a second (usually milliseconds). So your 00:00:13:24 above would equate to 00:00:13.960 if you had started from 25FPS timecode. Note that sometimes the leading or trailing zeros are dropped for visual compactness. But don't confuse that - 00:00:13:2 ought to mean 13:20, not 13:02 - it's digit position is not to be adjusted/switched.

In the 2nd clip, again, the leading zeros have been dropped for compactness (so, yes, it's seconds & frames). This happens much more frequently when designating a DIFFERENCE in time (as it would be rare that you would SHIFT a clip on a timeline by hours or even minutes, but much more common shifting by a few seconds or frames to "nudge" it to its exact intended spot). And clearly, the + or - refer to which direction the difference is going. + is Later in time, - is Earlier.

Not that hard once you get used to it.

hi
thanks a lot , i have read the the link
i will try it ! but i 'm tring to understand premiere seeing i'm paying the subscription for now

, as well as one or more on my Windows PC. Just do a google search on "timecode calculator freeware" and then take your pick.

might you please tell mewhich calculator do you use?

ok

video is based on frames , but in first screenshot there are audio clips why are they in frames ?

Time which DOESN'T need to be measured in frames, such as with many kinds of audio, would be designated HH:MM:SS.xxx where xxx is the fractional portion of a second (usually milliseconds). So your 00:00:13:24 above would equate to 00:00:13.960 if you had started from 25FPS timecode. Note that sometimes the leading or trailing zeros are dropped for visual compactness. But don't confuse that - 00:00:13:2 ought to mean 13:20, not 13:02 - it's digit position is not to be adjusted/switched.

may i know how did you calculate 00:00:13:24 -> 00:00:13.960 with 25fps

In the 2nd clip, again, the leading zeros have been dropped for compactness (so, yes, it's seconds & frames).

may i know what is it a nudge ?
i know alt+arrorow key move to nudge .. but i tried to translate nudge , i did not find a result
i know premiere uses the word nudge


Thanks a lot Scott, i really appreciate it!!!

I use Drastic's TCcalc on my Android phone & tablets, and Windows. But I also use the TC Calc from AVID (comes with Media Composer, MediaLog, etc). And I have a number of older ones, too. And I use some custom TC functions in Excel spreadsheets.

In fact, it ought to be fairly easy to build a TC calc, even in VisualBasic. Might be a good project to brush up my programming skills...

You were looking at those audio clips in a Video-based NLE, weren't you? So in those apps, EVERYTHING is referenced according to frame-based timecode, even if it isn't video. If you were to use something that is not necessarily video based, say Avid's ProTools for example, you could choose between referencing things using SMPTE timecode, plain FilmFrames (start at 1 and count up by integer), Time w/ Milliseconds, or AudioCD-frame-based timecode (each frame = 1/75 sec), or music Bars+Beats (good for midi use).

24 frames when reference to a 25FPS rate is 24/25 = .96. IOW, each frame = 1/25 sec or 0.04sec or 40msec. Seen another way, 40 * 24 = 960.

"Nudge" = budge up. To push to the side slightly, one way or another. A small shift. kleine Anpassung. piccolo aggiustamento.
In this case, it usually refers to the timing of items and the change of a clip's position on the timeline, without changing the clip's duration nor its internal start/stop window.

I uploaded a VERY basic SMPTE to seconds excel sheet a few years ago here (don't laugh at how pretty it is )

hi
thanks
i did not buy exel , but maybe i could use open office

[poisondeathray]

Yes, open office can open XLS. I can't recall but you might have to install a plugin or something

But I can't ever recall actually using it for editing purposes, it' s not realy useful to have total seconds

thanks , i installed , i would like a portable version to have on my usbstick
but tccalc is ok

wow do you use avid protools , i know it's the best program around and very tough to learn

now it's all clear

Yes, I have been using PT since it came out v1.0 in '91 (had to beg/borrow/steal to get the full manual ahead of time ). Other DAWs and audio/music editors have their own fine points, but for my money PT has always been the best. I don't find it difficult at all to learn, but maybe that's because it follows very closely to the paradigm of the sound recording/mixing engineer (which is what I trained as in Uni).

hi
i used for years wavelab (don't remember the version but i really love it) and cool edit 2000 under w98se or xp (i don't remember again) to convert my lps to cd
gave a look to avid but was really very difficult

there are so many audio editor , that i guess to get audition cc , should be a solid program

by the way thanks Scott , i really appreciate your help

[poisondeathray]

I don't get what you're trying to do exactly...

But you can display the audio in ms in PP, would that help you?

1) Set the sequence settings "audio display format" to "miliseconds"

2) In the timeline sequence, fly out menu, left click and checkmark "show audio time units"

That changes the usual SMPTE display to hh . mm : ss . ms notation. Obviously you can change it back if you don't like it

hi
i tried
but i did not find

Set the sequence settings "audio display format" to "miliseconds"

where is it ?

in the timeline sequence ,fly out menu is what there is in the screenshot ?
thanks!

I'm using PProCS3, and in it you go:
[Project | Project Settings | General], Audio Section: Display Format - Milliseconds or Audio Samples
Then, RightClicking the TimelineSequence tab in the Timeline panel, check or uncheck "Show Audio Time Units".

With Display format = Milliseconds, and SATU checked, your zeroed starting time looks like 00:00:00.000 (where right of decimal is msec 0-999)
With Display format = Audio samples, and SATU checked, your zeroed starting time looks like 00:00:00.00000 (where right of decimal is samples 0-44099, etc. depending upon samplerate)
With SATU Unchecked, regardless of Display format, your zeroed starting time looks like 00:00:00:00 (for SMPTE non-drop TC), or 00;00;00;00 (for SMPTE dropframe TC), or 0+00 (for "Film Feet+Frames", 16 or 35mm), or just 0 (for "Frames").
Those are all chosen in:
[Project | Project Settings | General], Video Section: Display Format.

PProCC might be slightly different, but not too much.
