“Rendering Required Files” While Multi-Camera Editing

[Chris Knight]

Sounds like a buggy nested sequence…when you edit Multicam in CS4, it has to render the audio from the merged camera tracks into a single file. That is what is rendering, but something is causing it to hiccup. I never encountered this in CS4, so I never looked into it.

Try importing the sequences into a new project and try again – this should purge the preview files, and hopefully you’ll be good to go.

Thanks, Chris. I’ll give that a try.

I’m curious, though, now that you mentioned Preview Files. I noticed that in the folder where I keep the footage and all the project assets, Premiere creates three folders: Adobe Premiere Pro Auto-Save, Adobe Premiere Pro Preview Files, and Encoded Files.

Since your suggestion results in the purging of the preview files, do you think that the same thing would be accomplished by simply deleting the contents of the Adobe Premiere Pro Preview Files folder? It contains several .PEK and .CFA files that constitute a not-insignificant amount of memory (about 1.33 GB).

Do you think that would work, thereby avoiding the need to create and import the sequences into a new project?

I would quit Premiere before doing this. I would also trash the Encoded Files folder as well. It won’t harm your project, as Premiere will just rebuild the files when needed.

The reason I suggest importing into a new project, is because it might remove an issue in the nested sequence. Sort of like when someone in Star Trek gets healthy when they’re beamed from one place to another. Odd, but effective.

I won’t have a chance to try any of this stuff until this afternoon, but I’m hoping it will work. I do have two last (possibly silly) questions.

1. You said to import the existing sequences into a new project. Am I correct in assuming that you mean both the “synch” sequence (the one where I have the separate video tracks synched together) and the “multi” sequence (the one where I enable the multi-camera editing)?

2. I’ve never imported a sequence from another project into a separate Premiere project. How do you do that? I don’t recall ever seeing an actual file in my folders that suggests it’s a sequence file. To put it another way, if I want to import some raw footage or title cards, I can do a “File – Import” (or just click and drag) to get a .AVI file for raw footage or a .PNG file for title cards into the project. How do I do that with a sequence that’s part of another project?

Thanks!

You can import sequences from other project files using two methods.

1. Copy/Paste. This is simple enough, if you’re dealing with a single sequence. You are not.

2. Start a new project. Import the original project file. Before it imports, you’ll be asked to select the specific sequences. Pick the two that you’re currently working with (the work sequence, plus the nested sequence). Premiere will bring place the two sequences, plus all relevant media, into a folder in your project window. Just double-click the main sequence you were workng in, and everything should look as it did before.

I tried creating a new project and importing the sequences, but I got a Runtime Error [R6025 – pure virtual call] after I selected the specific sequences to import.

Do you have any suggestions for getting around that?

I would suggest just importing the entire project and not go with a specific one, This will import all the folder structure of the project too.

If you want to clean it up just remove the bits you don’t want in the project. 🙂

Before John’s response, I ran an error fixing program, but still got the runtime error when I tried to import the specific sequences again.

Next, I deleted all of the folders that Premiere puts in (Auto Save, Encoded Files, and Preview Files). I started a new project, imported the entire project, and I still get the “Rendering Required Files” when I try to edit the multi-camera sequence.

Does anyone have any further suggestions?

What format are you working with?

It could just be that the render.relates to the audio being nested to see the waveform.

I multicam edit with the original audio outside the multicam sequence so video track 1 is the “multicam enabled” nest and audio tracks are a copy paste of the audio synced inside the nest. I find I have way more control this way and multicam is only looking at the vision.

Hope that helps.

Might make a tutorial…. 🙂

What OS are you running? A quick Google search suggests this is pretty nasty (your footage or the project file has been corrupted), but there are workarounds. Except they are OS specific.
