I'm using Roxio EMC9 to create holiday DVD's. The video is captured via Firewire from Sony TRV325E into Dell Vista Dual Core PC with 2Gb RAM and huge HDD resources. The drives are not fragmented.

Capture is good but after creating the DVD, scenes where I've panned across the landscape are very, very choppy.  

The film in the camera plays back perfectly on the camera and to all intents is good. I have recaptured the same film several times with similar results (and on different HDDs) and also written to DVD at slower speeds. Alas with the same results.

Any ideas what I'm doing wrong here?

Nothing wrong, just a fluke with Hardware Render that some video cards have…

Under Tools, Options, select Software Render and it should go away.

Sadly, this also means you cannot use any of the 3D transitions.

Elton:  Thanks for your question and James, thanks for your reply.  You are a genius!!

I was having the same problem and switching to software rendering fixed it.  The perplexing thing was, I DID have some DVDs with excellent quality and some without.  In trying to fix some of the buggyness of the software, I think I changed to hardware thinking that would solve the bugs.  Looks like that was a bad choice and as I backtrack what I've done, the DVDs with good quality were created before I changed from hardware to software and since then, they've all been bad.  But I change back to software and now things are great.

James, thanks for your help!

I think the main bug is with the hardware render.  I have no clue why Roxio even has it.  It won't work properly with high end NVidia cards.  I always use software rendering, and the extra time it takes to encode, is minimal, but the increased video quality is significant.

I certainly agree that the difference is significant.  But it seems to me that the software rendering is faster than hardware.  During the encoding preview, with hardware, the motion is less than normal speed but with software, the motion is faster than normal.  Haven't actually timed it, but I think software is faster.

Hardware is faster, replace 'seems to me'  with a stopwatch!

But I find the difference on my PC to be so minimal that it isn't worth it.

Thank you James and Grandpabruce.

I had heard from a colleague that the 'jitters' were probably down to any background programs that were running at the same time. So I had attempted to experiment with certain programs off but didn't get very far. With 2 GB of RAM on board I thought the PC should handle it but I got nowhere. So I have been trying to minimise all the programs on my laptop and feed the films on there. This would have the added bonus of being able to download my films as I take them when I am on holiday. Sadly, I keep running into an error:

Capture stopped, maximum file size of 4GB has been reached.

This has really wound me up because I'm capturing 10GB+ on the desktop!!!!

So I shall try the Software Render solution back on the main PC and let you all know how I got on.





Glad to be of service to ricargo by asking the question first

The 4gb file limit indicates your hard drive's file system is probably FAT32, which has a limit of 4gb for any one file. If you convert your file system on that drive to NTFS, you won't have that file size limitation.

The encoding process does not use your RAM.  It uses your CPU and the GPU of your graphics card.

So simple when you know! Many thanks Larry. Don't have the laptop with me at present but shall have a looksee into changing it over.

AMD 64 x2 and NVidea 8600GT / 256Mb graphics card.

Tis' a day for learning without a doubt. Thanks again grandpabruce.

Good Luck and let us know how it goes.

That did the trick guys.

1, changed the render to software and result is great on my desktop PC.

2, on the laptop, deleted my previous attempts before changing the file system to NTFS. Result - perfection. Just brought in the complete film, had a bit of difficulty adding the movie (kept getting the Add Movie operation failed 80004003 error????) but worked around this and currently it's burning.

So thanks again. It's very much appreciated.
