how to split clips

[max123]

Hi Everyone,

Does anyone knows how to instruct premiere to export a timeline into several 2GB clips? I have to export a 1.5 hour long timeline to After Effects in uncompressed format. (In after effects, there is a command to split clips at X GB, but I cannot see it in premiere)

Since there are A LOT of effects on the Premiere Timeline and an AE import makes some of the effects a little different or disables those completely rendering to Uncompressed is Easier.

A single 1.5 hour uncompressed file would be too big, of course.

Any ideas?

You could redefine the work area and export it in chunks, one at a time. Since it's uncompressed, it should be easy to determine how long 2GB needs to be (I don't know it off hand, but it's probably really short).

Of course, you do know that you can use Adobe Dynamic Link to import a Premiere timeline into AE with no generational loss, right?

In fact, you can export your 2GB chunks that way. Go to AE and import the PP project (import it as you would any other file, not as "import PPro project"), choose your sequence, put it in a composition, and then export your split files using AE's settings.

This is assuming you have AE7 and PP2 or higher (I think, you might need CS3).

Unfortunately Premiere doesn't have that type of feature. You could just import your timeline into AE and export from AE. That's your best bet.

Another thing I wish Premiere had was a way to limit the size of CAPTURED files. When capturing from a tape, I've ended up with files in excess of 20GB, and that's kinda annoying.

Use scene detect. It splits the clip into smaller chunks based on when you start and stop recording. On CS3 HDV capture doesn't have this feature, not sure if they've fixed it for CS4.

It's interesting that you're getting 20+ GB file from tape though. At 60 minutes per tape at 25mbps file size shouldn't exceed 13 GB/hour.

Sorry, I miscalculated. The largest file I have is 14GB+, and although I ALWAYS use Scene Detect, it was an event so they let the whole 83 minute tape run I think - or most of it. I would have liked to limit it to like 2-3GB per file.

Like I said in the original post, Importing in AE is annoying, because I will have to redo a bunch of effects which won't appear the same way they do in premiere. Also, some superimposed text whic look fine in Premiere appears with a black background in AE, etc. Since the project lasts 1 hour+ and effects occur quite often, I was hoping this would be a last resort.

Does anyone knows a way to match the effects between the two then?

(import it as you would any other file, not as "import PPro project")Just use the normal "import>file..." dialog box. Once you do this, your sequence appears as one layer in AE, and your computer will run an unseen PPro process on your computer, which renders all the fades and effects like a giant plug-in. And it looks exactly the same. You can do the same in reverse in PPro and import an AE composition, forcing a hidden AE process to do all the rendering.

It's why Adobe totally rules.


Another thing I wish Premiere had was a way to limit the size of CAPTURED filesBatch capture! You can type in the values (in multiples of whatever) without scanning the tape. It'll only take you a few minutes. Problem solved!

That doesn't work if you let the tape run for a long time (filming an event from a WIDE ANGLE.) Too bad they don't have another feature to limit it.

I don't get what you're saying, of course it works. I've done it myself in almost the exact application you describe. I'm not talking about scene detect, I'm talking about batch capture.

In PPro, using the capture window, you manually define something like 16 segments of 5 minutes each (or whatever equals 2GB), each one creates a proxy in the project window. Then select the proxies, right-click and hit batch capture, and the tape scans and captures each region as a separate file.

It takes a little bit of time to set up, but you don't have to scan the tape to define the regions (you just type in the in/out time code), and if you're fast with a keyboard, it will only take a minute or two, then you can let it capture the clips and go make a sandwich.

Gotcha. You're right. For some reason I was thinking SCENE DETECT instead of BATCH CAPTURE. That is a good workaround. Obviously not as easy as it happening automatically but it's still a great way to do it.

Great tip! Thanks so much! Sorry for the confusion!
