timecode question

BabaG wrote on 3/26/2005, 11:19 PM
i work with older libraries sometimes that are archived on vhs tape.
those vhs's have a window burn but no other ltc or vitc. premiere
allows a user to assign timecode to such uncoded media. this means
i can go to the media's start frame, look at the window burn, and
type in a matching timecode value giving me, in effect, timecoded
media. can i do this in vegas? or am i stuck with the media defaulting
to zero as the start? asking as i'm a prospective new user.

thanks,
BabaG

You can assign a start TC to the TL,
don't know if that solves your problem or not.

thanks bob. actually, that's not what i was getting at. (btw, been enjoying
reading your back and forth with filmy on edl issues.) i have betacam
masters that the vhs tapes were made from. i need to be able to export
an edl (probably cmx) that will reference the original betacam tapes.
problem is, my intermediates (the vhs's) don't carry any timecode on
them other than the burn in. that means any edl i export will have
incorrect timecode for the source columns unless i can assign the
correct timecode to the captured media (captured from the vhs's).
iow, all my media captures think their start timecode is zero. i need to
change that in the software somewhere to match the window burn of the
captured media so that my edl will be correct. changing the start tc
for the timeline addresses the 'recorder' columns of the edl, not the
'source' columns.

if i'm unclear, i'll outline it:

1. betacam master tape start = 02:23:17:09
2. dubbed to vhs with only window burn
3. vhs captured to avi
4. avi file start = 00:00:00:00
5. export edl thinks betacam starts at 00:00:00:00

6. reassign avi media start time of 02:23:17:09
7. export edl now thinks betacam starts at 02:23:17:09

premiere allows a user to do step 6 reassigning of a new start value
to captured media. can i do this in vegas? they allege it can be done
in liquid edition, although the version i have doesn't seem to actually
do it.


thanks,

If you right-mouse-button click on the clip on the timeline or in the media pool you can choose Properties / Media / Use custom timecode: and type in any starting timecode you wish.

I don't know if this will help though because by this time you already have the media in your project. It doesn't save this information in the file; it merely references it within Vegas.

There's more than one issue here. How are you going to capture your SP footage with TC? I think you can do this with the SD Connect, ah no yes you can if you've got 9 pin to the deck.
One way you could do this and it's a bit of a PIA, capture from the Super OP of the SP deck, that'll give you a capture with burnt in TC. Than capture your VHS, match the two on the TL and then recapture the SP. I had to do something like this once before when I had a tape with intermittent TC, we rendered it back out and did a PTT to DVCAM and then captured that back in, added the TC FX in Vegas for a DVD copy for the client to give us back a rough EDL and all was sweet.
You can get Vegas to display source TC on the TL by the way.

chienworks,

thanks. so you're saying that this applied timecode will not output to an edl? just
for internal use by vegas?

bob,

i already have the vhs's captured and on disc - no timecode. it's a library basically.
idea is to be able to export an edl that has the correct timecode reference to the
original betacams. recapturing is not my issue as the edl is intended to be sent to
an online facility who will take care of that end of things. saves me any machine
headaches but at those kind of prices means i really want the edl to be right.

thanks,

>>>so you're saying that this applied timecode will not output to an edl?<<<

I will say that manually entered TC *Does* export to EDL via the CMX script EDL. However keep in mind that this exported EDL is not very good as being usable. What Kelly meant was that any TC that you enter in does not change what is in, or not in, the file already. in After Effects you can render and write a new TC track and there are some other thrid party apps that will also write TC. However Vegas has a mind of it's own and records/reads TC from another spot all together. SCLive is the only app that I know off that will write and read both Vegas *and* Premiere TC.

You know I suppose one possible solution to all of this is to just use SCLive to capture all footage in.

filmy,

can you advise what are some of the third party apps that will rewrite the tc
for a file? sounds like a potential solution to some of my issues.

thanks,

After Effects and CaptionMaker both do it, but expensive to get if all you want to do is write new TC.
FireStore™ DV File Converter is another. (Somewhere in time this used to be free. I have no idea if you can track down the free version anymore) There used to be something called aDVanced DV convertor Pro that did the more or less the same thing - maybe this was bought up by FireStore.

In a similar vein there is yet another DV Converter that works really well. It's time has sort of come and gone and it is not really supported anymore but it can make low rez files for offline use with TC intact. You can also convert Non-Drop to Drop. It does a lot of nifty little things...I like it. :)

Now keep something in mind - none of these work with Vegas that I am aware of. Main reason is the location of TC in Vegas captured files, and that Vegas only reads TC from that location. As open as Vegas is to being able to work with "any" type of media it is very propitery when it comes to reading TC from files.

If you work with MPG (namely MP2) you can download ValidTC, which was used for Pinnacle created files. It will write new time code, but does not work on AVI files...at least I don't think it will. Never tried to see if it did as it was made to work on MP2 files.

And back in my D/Vision days a company was coming out with logging software for windows - it is still around. It won't write new TC to a file but it may be of some use. The Executive Producer is logging software that will log incoming video with TC. Problem is, as of yet, it doesn't output to anything readable by Vegas.

I found this - it is from training for an older version of Premiere but it is informative none the less.

filmy,

posted this in thge edl generator thread too.

do you know if any of the apps you mentioned which address the issue of
altering timecode actually rewrite the code vs. applying premiere (or other)
proprietary code? i have attila mezei's dvconversionsuite which does the
latter. the difference is that premiere allows writing of a start number into
the file header. since premiere doesn't actually read embedded code, it
calculates position based on either this user entered number or the actual
embedded start frame. after that it's all done by calculation. a rewrite of
the code would make the new code accessible to any app which could
read embedded code. if they just apply 'premiere timecode' it would only
be readable by premiere.

also, automatic duck has a free aaf plugin for fcp that i tried and couldn't get
to work. would want to be careful before plopping down the $500 for the 'pro'
plugin. otoh, they probably put more into the $500 item than the free.

cuibono is another company making edl/project conversion software which
seems similarly priced. the app i can think of off the top of my head is
edlconvertpro.

I know some of these write TC on each frame - which is what it should do. But I am not sure, I guess you would have to get a hold of the developers to find out for sure. As for the "premiere timecode" vs other forms - I can say this for a fact - when TC is layed down in the camera it has nothing to do with "premiere timecode" so it just has to do with how it is read from the file. I know that SCLive will capture the timecode info and the same info is read by both Premiere *and* Vegas. Somewhere along the line with all of this TC talk someone said that SCLive's developer got a hold of SoFo to see where they read TC info from and thusly it was added to that location in SCLive. Vegas "ignores" TC info not in where that location is. Most other programs seem to read TC info fine from other files. The only other programs right now I know of (there might be others) that will also read Vegas TC other than SCLive is the latest version of Visual DV Time Stamp. (For doing quick and easy window burns from DV only files this is now a great little tool) and CatDV Pro. Actually CatDV will give you all details it can find in a file - and it has many export options for files. Vegas is not one of them however.

But going back to your question - I wish I was a good coder because I would have been on top of this a long time ago. On the windows side this seems to come down to how DX/DirectShow deal with it. If you want to take a swipe at coding Timecode Structure is a good start. And to see a sample: Sample Structure. Now get coding!

I already posted about Automatic Duck and the Cuibono stuff in the other thread. Cuibono makes EDL Convert but it is an audio EDL app, not video. While it does work with video somewhat it is not too good at doing what Bob and I were talking about. And thanks about the info on aDVanced - that was what has no become the product put out by Foucus. I thought as much but you said the developers name and I got this back: Attila has now sold his company so you need to go to Focus Enhancements at:.

just tried dv converter and it seems to only add the 'premiere timecode,' and
only based on the first frame of the file; user can't input their own number
anywhere.
