Do the RAID controllers have diagnostic utilities? As a start, try to run a speed test on the arrays. Here’s an app, if required.

The input levels are adjusted up or down depending on the source audio and the how the finished product will be viewed. For broadcast video the mixed output level should be -20dB for a reference tone, -12dB for dialogue, and -9dB max. For web delivery these levels would typically be increased by a few dB.

Also note that Adobe no longer allows users to update payment settings on its website. Users need to call customer support to change credit card information.

Lossless or low compression codecs are the best choice for your library master. Keep the same PAR as your source/sequence and just realize that it might not be depicted properly in common video players. Among the standard codecs AVI-422, AVI-None, or PNG will produce high quality results. Try exporting a short clip to see which looks best. Exporting QuickTime formats on a Windows PC can be problematic because of QT color management issues.
To export a file for viewing with common media players, try a moderate- to high-bitrate H.264 with Main or High Profile 3.1 and square pixels. Render two short test files at 640×480 and 648×480 to determine which resolution looks right compared to the source footage.

What is the processor and disk utilization?

Sorry, one more (and most likely): Check whether the speaker icon is “on” on the left side of the audio track. You might have inadvertently turned it off.

Check each of the following parameters:
– Volume setting in the Effect Controls window for each clip
– Audio Gain… under Clip > Audio Options (or right click the clip)
– Track audio level in the Audio Mixer window
– Master audio level in the Audio Mixer window -
The codec might not be the issue; many media players assume PAR=1.0. What software did you use to view the exported file? Did you try to import the file into Premiere to view?

Both Premiere Pro and ProRes are designed to maintain the source format. If you want RGB output from Y’CbCr input, I believe you will need to transcode to a non-ProRes RGB codec. How will you be using the output file, and why does it need to be RGB?

Good to hear you were able to resolve the issue. I haven’t worked with 5D footage so my recommendations are more general. At the very least, record/convert audio to wav files (preferably at a common frequency). Regarding video, Premiere works fairly well with a variety of codecs, but low compression or uncompressed formats can be processed more easily. If you would rather not transcode your source files to a different codec, consider converting to all I-frame.
That’s just my opinion based on trying to reduce the risk of system crashes. There are several archived threads that provide more specific guidance regarding 5D footage.
