Surfer,
[surferj45] “If captured AVI files are on the Raid 0 drive then it has to read and then write from the same drive, namely the Raid 0 drive, thereby slowing down the rendering.”
You are worrying about a non-problem. Rendering is a CPU intensive operation that is little effected by drive speed, particularly a raid 0 drive speed. If you want to render faster, get faster CPUs. Since the CPU that you have is about as fast as it gets, the only way to make it significantly faster in Vegas is to go to multiple, multiple core CPUs like Xeons. Honker hard drive arrays are for servicing real-time playback of multiple streams of video, particularly uncompressed streams. A single drive will keep up with most complex rendering even if it has to do both I and O, but your real-time preview could suffer with just a single drive pulling multiple streams at once. So you have a Raid 0 array of 2-4 drives to help you with the real-time preview of your editing, but it won’t do much at all for your rendering.

#88,
[vegasuser88] “Could someone tell me what the best option is for an external hard drive? I am looking for performance rather than security or backup. Something that will decrease my render times?”
I don’t understand the answers that you have received here. A high performance hard drive isn’t going to make any appreciable difference in your rendering times because rendering stresses the CPU(s) not the hard drive(s). Any hard drive, internal or external, will keep up with the rendering. If you want to spend money to decrease your rendering times, get faster CPU(s) and a mobo to go with them if necessary. High speed hard drive arrays are valuable and necessary for multi-stream uncompressed playback and such, but won’t benefit rendering hardly at all.
Am I missing something here?

Terry,
[Terry Esslinger] “My next test will be to record at SP which Sony states is the 2 hour recording on single layer disc.”
So…, how did that work out? That’d be a bit rate of around 4.5 mb/s which is similar to the bit rate that most Hollywood titles use and every set top or DVD-ROM player should handle well.

Mr.,
[mr_gfx] “So, we have Panasonic DMR-E55 recorders that work fine for copying a tape to a dvd. but, sometimes the dvds made on this recorder do not play in other dvd players.
not sure why.”
I use a Pana DVD recorder and have never had a problem…, but I always burn in the SP (2 hr. mode), The bit rate on the 1 hr. mode is just a bit too high for some set-top players and apparently for some computer DVD-Rom drives.

Terry,
[Terry Esslinger] “Apparently the encoder could not keep up with the incoming video and there were NUMEROUS glitches where the video would just stop for a second and then catch up.”
If you are recording on the Sony and playing back on your set-top DVD player, I’d guess that what you are seeing is not recording errors but rather playback errors. 1 hour recording mode on DVD recorders is often not a good idea. Although it may be slightly better quality than 2 hour mode, the bit rate will be a bit too high for some set-top players resulting in video glitches like you are experiencing. Thus, it’s a good idea to use the 2 hr. mode when recording on a DVD recorder for playback on another device, even when the amount you want to put on the DVD is an hour or less.
However, if you are experiencing these problems when you both record and playback on the Sony DVD recorder, then you have a bum unit. It ain’t supposed to work that way.

Edward,
[jeditdv] “[Peter Wright] “Just for the record – Canon Printers do this too – I have an i865 and a Pixma iP4200.”
Not in the US.”
The problem with Canon printing of DVDs in the US is not a matter of Canon’s choice but the result of an Epson Lawsuit claiming patent infringement. Most Canon printers and I believe all Pixmas are capable of DVD printing that is not enabled in the USA. It’s a 10-15 minute job and the ready purchase of a $20-25 CD/DVD tray on e-bay to enable this feature on these printers. I’ve used both Epson and Canon and believe me, the Canons are just as good, more reliable, and nearly twice as fast as the Epsons, plus Canon ink or compatibles are less as well. It’s more than worth the small hassle to go Canon for DVD printing.
A quick Google found this:
….or this and you can even make a homemade tray:

Naveen,
[Naveen Mallikarjuna] “Do I need to contact Matrox for this?”
Maybe, but I’d sure try the Matrox Editing Cow Forum and Matrox’s company forum first.

Craig,
[craigd] “has anyone worked with Sony XDCam HD and editted it on Premiere Pro? Im curious as to how the data rates can effect your edit. I think there are three different data rates, does the highest rate function as well as the lower rates and vice versa? any info or links for more info are appreciated.”
Adobe products don’t support MXF wrapped files like XDCam, any flavor, on their own. For the time being at any rate, Adobe is looking to their partners to supply this functionality. This applies to Pana P2 and Infinity MXF wrapped JPeg2000 as well. Some of their partners will or shortly will support them either directly or by transcoding. Perhaps someone makes a utility to rip the MPEG2 out of the XDCam files, but I haven’t looked into it, and it sure wouldn’t be the greatest workflow. So, if you want to edit XDCam with PPro…, look to Matrox Axio to edit XDCam files natively, or probably Cineform to edit them by automatically transcoding to Cineform’s codec.

Tip,
[Tip McPartland] “Music to my ears. Thank you so much for the good news.”
Be very careful about reading too much into that. Remember that Infinity’s JP2k will come in an MXF wrapper and I don’t think that the Adobe products can deal directly in any way with MXF. If you want to edit Infinity’s output using Adobe products with any reasonable workflow in its native format you’ll need to wait for Matrox Axio’s implementation. This will happen, as Matrox has just signed on as a GrassValley partner supplier, but I don’t know how soon that is liable to happen. Be aware that Matrox will deliver Axio drivers for all flavors of Sony and Panasonic MXF very soon, so they are very MXF aware. Perhaps we’ll have some indication at IBC. Tim will know whether Cineform will support the Infinity files, which would be another way of editing them with PPro, but of course that’s a transcoding, not native, solution.
The one thing that you can be almost certain of is that Canopus will have the first native solution, but only when you edit* with Edius. All Apple or Avid Infinity file editing solutions will involve some degree of transcoding or file preparation, although Avid’s could be a quasi-native editing solution, i.e., not truly native, but happening in real-time.
