Quick After effects question
show user profile  Zman
This sounds super basic yet I cant find it on AE...

lets say I have a sequence in a composition.
How can I know what frame I am currently at from the sequence ( the sequence didn't start from 0) ?

ctrl + click on the frame stamp in the bottom left window. it should read 0:00:00:00 - will turn to frame 0000 etc

I know how to switch from frame number to time number ...
But it show's the comp's frame number ... not the sequence's.

Really ?

Ill explain with a simple example:
I have a sequence of 270 jpg files: zman00230.jpg - zman00500.jpg
just to be clear:
The first frame in the sequence is zman00230.jpg
The last frame in the sequence is zman00500.jpg

When I put it in a comp, the comp's frame 0 will be the sequence's file name zman230.jpg right?
the comp's frame 100 will be filename zman00330.jpg and so on, right ?

Is there a quick way for me to locate which filename from the sequence im on at each spot on the comp's timeline ?

The most straight-forward way i can think of, is to create a temporary Text object, put it on top of the composition, and then use an expression to link the current frame + 230, or the filename, to the input of the text object..

That probably sounds complicated but it`s not, 5 minutes on google and you can put together a quick expression that`ll do it.

Don`t know if there`s a built in way to show the current frames filename.

Here`s an example:

Inside your comp, click the Text tool, click on the comp and type something ( doesn`t matter ).

Change the colour of the text so it`s legible.

Click the little arrow on the Text layer and find the Source Text property. Alt-Click on the little stopwatch to add an expression. In the expression field type in:

timeToFrames(t = time)+230;

All this does is adds 230 to the current frame of the composition and displays it as text. Obviously not ideal if your situation is more complex but might be useful..

Thnx ScotlandDave,

My situation is indeed more complex (compositions within compositions with many different sequences, some of them have bugs in specific frames).
I just thought there's some built-in option in after to locate the specific frame from a sequence you currently view ... seemed obviously needed for people who work with after allot. apparently I was wrong.

There may still be a way via expressions and the above method, i just dip into the language reference or google whenever i need it for a specific task, so i don`t know all of the parameters/properties available off the top of my head. Worth looking into if it helps with your current problem..

Yeah Zman.....a little expression is prolly the only way.

With that said you COULD pre-comp each sequence and then set the start frame of the pre-comp to the start frame of the sequence..then you would be working in the frame range of the sequence.
Again...it's a work-around.

And yeah....gotta say in my 16 years of using AE has my daily application I have never needed to do that.....or was in a situation where I couldnt just mentally subtract 230 or such to get a specific frame.

Looks extremely annoying. AfterEffects is indeed a PITA to work with when layers start to build up..

As i say though, for debugging purposes, i`m sure there`d be some way to leverage expressions for example to show the current or offsetted frame of the currently selected layer, or something along those lines.. I`ll have a little look in the docs later and see if i can find anything. Just cos i`m a nice guy like that..

Looking at this.....

Are all your image sequences precomped?
If so...then why not just set the precomp start frame # (in timeline) to the start frame # of the sequence.

Then whenever you are in your MAIN composition with all your precomps...and you land on a frame, and you wanna know what file 3 relevant to the sequence...simply open the sequence and your playhead will be on that frame.....and since you had previously set that precomp frame # to start at the sequence frame #..you will see the proper frame.

Hope that makes sense.
Again.....a work around.

Interesting flow below......I typically use more precomping of 'sections' when I do long linear pieces like this....however I am sure there is a reason you need all of it in 1 comp...

not your question but looking at your comp it might be usefull to use this :

As for your question, precomp your footage with an appropriate frame offset of start point as Jim mentioned, if you want visual feedback, add a text filter > numbers and set type to timecode and click current time/date.

my god precomp that up into separate scenes or sequences

Go into your precomp hit
"I" =go to beginning of Seq
"B"= move start marker
"O" = got to end of Seq
"N" =move end marker
Right click in marker and go to trim comp to work area.

Go back to your man comp
ctrl click on the time will turn it into frames
Slide to frame your looking at if you double the precomp

The precomp will open and tell you what frame that is.

When importing a Seq it automatically set the frame rate to 30fps
If that needs to change right click on your footage and go to interpret footage, set frame rate.

edit:
man comp = comp if no precomp killed the mood
