Disaster making HD WMV9 file

MH_Stevens wrote on 11/15/2006, 8:54 PM
I just rendered a 29 minuet HD Vegas project (captured with cineform) to WMV9 with frame size 1440x1080 and no second pass. Firstly it took 34 hours to render on my 3.4gh machine, a ratio of 1:70! And after all that it played at a very jumpy 2 (yes two) fps and the picture looked no better than the SD DVD made with DVDA.

Is this not the way to make a HD WMV file?

Your wmv file is probably fine. Your computer just isn't fast enough to play it. I know mine sure can't. You can download some HD wmv files from Microsoft and see if they play back any better. They don't on my system.

Yes indeed, 1080 WMV is one heck of a thing to decode in real time.
720p seems way less taxing on the CPU.
I seem to recall though that some of the top end graphics cards can decode WMV.

nVida's PureVideo decoder will decode wmv files on some graphics cards.

Hmm, a 3.4ghz should be able to handle playback. What bitrate did you use?

Yes, try reducing the bit rate and/or render to 720. My slower machine (AMD 2800) can run that OK and looks very good. My AMD 2x 4800+ can run 1080 wmv9 at 25fps without hesitation, but I can't do that with the file on a firewire connected HD. Must be on an internal HD, but I expect an eSATA would do it. I see data rates of 40MB/sec (when WMP pops a figure into view).

Render time for wmv-HD are terrible high. Another option, delivering better quality with a lower render time, would be to render to DivX-HD.

Just as another hint.

There was a thread a while back that SPOT suggested what to use for WMV-HD for best results. I think it was 8 meg bitrate. The WMV-HD's from Microsoft play back fine in Media Player.

I used the Vegas default settings save for the resolution. I will try again tweaking bit rates. Anyone find the Spot article referred to here?
