RE: [Avid-L2] Link quicktime dsrl and traditional import

 

The fit to fill on a traditional import can happen if you say have a graphic that is say 10 seconds and you import it traditionally and cut it into a sequence for offline.  Then they make a revised version of the same graphic but for whatever reason it's a different duration like say 12 seconds.  When uprezzing later if you batch import that clip Avid will sometimes, I say sometimes but it may be always, compress the 12 second clip's entire video into 10 seconds.  The result will be a sped up clip.

You might think well if the revised graphic is a different duration it should have been reimported and recut into the sequence and you would be right.  Unfortunately in the ballistics of online that doesn't happen all the time.  That is what I'm referring to when I say fit to fill.  It's the closet Avid function that describes what happens.  I've seen weird cases where some how a 30 minute import thought it was only 3 minutes when imported into Avid and the resulting batch import looked like a time lapse.  This stuff use to happen more when it was a common practice to give imports tape names to keep track of where the imports came from.  That would create the double whammy when the sequence got decomposed Avid no longer thought of the imported clips as 30 minutes in duration but now it was only the length that was used plus handles.  It is in this hybrid state of a clip that was imported but then made to look like a tape source that most of the issues I've seen come from.

As to the duration concern you point to relinking the referenced clip to the ama clip and that's the case I mentioned of relinking master clips requiring virtually the exact same duration as you say.  But what about after adding the appropriate matching column to link with to both clips and then just relinking the sequence and not the reference clip?  I know  that has worked with tape based clips just not sure how a traditional import reacts in that situation.  A sequence is considered a series of sub clips as far as relinking and not the same as relinking master clips.

As the underlying reference clip is basically showing the master clip then if the AMA clip does not match the duration of this clip by even a frame then I guess Avid just doesn't recognise that it's the same clip.  In the same way that if you don't give the reference clip a disk label (or whatever) it won't relink, if the duration doesn't match then it won't relink.  

"Doesn't the Avid sequence just match the custom column and time code and go on it's merry way at the sequence level. "

You mean if the clip contains the timecodes needed but maybe not the correct overall duration? I'm pretty sure it doesn't do this, it's trying to relink the reference clip to the AMA clip, the whole master clip must relink in order for the section in the timeline to relink.  That's my experience anyway.

I didn't realise Avid does a fit to fill on imported clips? Why would it do this? Do you mean in a batch import scenario? If I import a 25fps clip in to a 25fps project Avid won't change the duration of that clip.  If I take a 23.98 clip, import it in to a 25fps project then Avid will change it's duration for the project frame rate, so when I AMA back to that clip later the duration will be different as AMA is showing as 23.98 and imported clip is now 25fps, the duration will be different and there will be no relink.  The only way to relink this clip now is to transcode the AMA clip to 25fps which should hopefully create a clip of the same duration as the original import.  This clip can then be relinked.  

Correct me if I'm wrong but all my experiences point to duration, start timecode and one other thing.  If you match that, it should be bulletproof.

That's the process I understood too.  It sounds like unlike tape name the other custom columns don't balk at being given a name like tape name sometimes does.  I'm primarily on a 6.5.4.7 SNDX these days so I'm not sure if I have all the options for relinking that later versions do but I do see disk label under the more along wth several other columns.

As to the matching duration I'm curious.  I know a master clip will not relink if the duration is different.  I do recall many years ago that the tolerance for this was opened up to a small extent but I think that was just a few frames IIRC.  Given a sequence will relink based on tape name and time code and now there is the option to relink based on other columns and time code why would it matter if the ama'd clip has a different duration.  Doesn't the Avid sequence just match the custom column and time code and go on it's merry way at the sequence level.  With traditionally imported I know Avid can add a fit to fill aspect if the new clip is a different duration than the original but I wouldn't think that would apply in this case or does it?  In the original post the original source material was imported traditionally so does that fit to fill problem have a potential to rear it's ugly head?

Sorry I think i sent this last reply just to John by accident.  We'll try that again...

It's very easy to relink basically anything to anything using the right metadata.  The process for what you're trying to do is simply;

Show reference clips on your sequence and find the clips you want to relink.  
Give them a disk label/tape ID/make a custom column ( I never use tape name any more, it takes more steps to apply, it wipes source path info when applied, and like John says, it sometimes doesn't take - I only ever use it for actual tapes).
Now AMA your clips and give them the same disk label/tape ID/custom column.
Check start timecode matches with your reference clips and your AMA clips and that, most importantly, the duration is the same (if it differs you cannot relink, you'll have to eye match the clips back in).
Select the AMA clips.
Right click the sequence and relink.
Use the relink settings: 
          relink to selected items in all open bins
          relink by: start timecode and then choose disk label from the drop down menu (if you used tape ID, then choose tape ID, if you created a custom column then choose your custom column           from the list)
          hit ok

As long as you have the correct start timecode and duration, you can give Avid any other bit of metadata and you WILL relink your clips.

I agree with changing by modifying the ama clip start time code if it will let you.  Sometimes that won't be allowed, but I don't recall exactly what gets in the way.  Different frame rate can deny adding a tape name in my experience.

Once the time code is matched I'm not sure if it will directly relink as traditional import uses the source file name or some such under the hood thing.  This is a Scott Freeman area of expertise.  Our AE's routinely add tape names to facilitate relinking or has been suggested Disk Label or perhaps some other column would work.  Remember you need to modify the sequence referenced clips and then match the new ama sourced clips to match for a relink.

It would be great if the ama link once the time code is matched would relink to a traditional imported clip of the same file but I'm pretty sure that usually doesn't happen.  I'd love to be wrong on this.

Just change the AMA timecode to match the import timecode, as long as duration is the same and it has one other matching piece of metadata e.g. disk label, it will relink.

Hi All. Maybe this is something that was discussed here, but I couldn`t find it.

I worked on a proyect a few years ago with dsrl material, so I imported then via tradicional import.

Now, I open the project and I Linked via ama all the files. When I try to relink the sequence, I realice that TC doesnt match.

So, testing, when I import a dsrl mov file, the TC start is 01:00:00:00, but when I ama link the same clip the TC start is 00:00:00:00

Someone Know why is this?
Thanks in advance.
