In cleaner you can specify a fade up on your audio track…..try a quick 5 frames or so and see if that clears it up….

you remove the DVDSP app from the apps folder, then do an install of DVDSP 3 you will get the export to MPEG-2 function back and DVDSP 4 will work fine. Just rename DVDSP 3 to something you’ll remember and bring the DVDSP 4 app back in again. The DVDSP 3 install reinstalls the export module.
All our systems are configured this way. This is ideal for us because we use the straight export to MPEG-2 for quick approval DVDs for the client and compressor for the final multi-pass variable bit encodes. Don’t forget that you should still use APack to encode your audio, so you still have to do a two step. I export the AIFF audio track (after a mixdown) then start the MPEG-2 export (single pass CBR arond 6.2 mbps) then I launch APack and do the AC3 encode while the MPEG-2 is cooking. After the AC3 is done I launch DVDSP 4 and by the time that loads the MPEG-2 is usually ready. Otherwise I build a quick menu in Photoshop while I wait.
I am doing all this on a Dual 1-gig G4 machine….my old faithful….this machine is going to be the first piece of hardware to end up in the Tilt Media museum…it has been an awesome run!

As far as the external recorders, it is also best to use DVD-R media not DVD+R. Seem to be more compatible. Also I never use the maximum encoding setting, but use second from the best….helps keep bitrates down.
Never had a problem disc….I also use Maxell media exclusively.

This usually depends on how much post-processing you need to do. The compression apps provide a lot more control and allow batching. Straight out of FCP you can determine the size of the image, bitrate etc. Less control of color correction, sharpening etc.
Depends on what you need.

Most of the RAIDs shown at NAB were hardware RAIDs. Here is what I found at Ask.com:
Hardware RAID
The hardware-based system manages the RAID subsystem independently from the host and presents to the host only a single disk per RAID array. An external RAID system moves all RAID handling “intelligence” into a controller located in the external disk subsystem. The whole subsystem is connected to the host via a normal controller and appears to the host as a single disk.Software RAID
Software RAID implements the various RAID levels in the kernel disk (block device) code. It offers the cheapest possible solution, as expensive disk controller cards or hot-swap chassis [1] are not required. With today’s fast CPUs, Software RAID performance can excel against Hardware RAID. The performance of a software-based array is dependent on the server CPU performance and load.So it seems that if critical performance is required you would opt for a more expensive software RAID. There is more loading on the processors in a software RAID system (JBOD) and I would guess that the more drives in the JBOD the more load there is to manage the handling of data to each drive.
I built a four-drive Ultra 320 SCSI JBOD RAID on a dual channel ATTO card and I get great performance. But not as good as a true hardware RAID. It has served its purpose however.
In our G5 dual 2.7 ppc’s we have the Jive block with three drives across a Sonnett card. These have performed flawlessly with DVCPro50 and uncompressed SD….I can even run DVCProHD without a hiccup.
Still, the hardware RAIDs do more of the work for they system and therefore more of the processing cycles go to the app you are using. In HD applications where we are trying to get maximum throughput and as much realtime as possible the hardware RAID might just give you the performance boost you need.
That being said, I will probably build a 5 drive JBOD with a Sonnett card for our DVCProHD editing…

Please provide us your system specs, what your source clip is and what format you are encoding to….also any custom settings you set up.
Then you’ll have your answer.

Coup0le things to try…..send the encoded clip to a different drive. Try changing a preference then changing it back. Kind of resets the prefs file. Try exporting to a different codec. If you have been exporting audio, try exporting video only.
Hmmm, that’s all I have.

More info needed…..what platform? Have you updated ANY software recently?
Give us some system specs, including what kind of files you are using to encode etc. Frame rate/size.

I always recommend developing a workflow to create WMV on a PC. Sorenson Squeeze has a decent WMV encoder as well. But getting your clip to a PC and doing it there will give you the best control and the best output especially for full-screen playback.
