Preview = Excellent / Rendering = Garbled!!!!????

Nastyj wrote on 11/14/2002, 12:04 AM

I'm having problems with rendering for final output to tape. I capture and lay down my shots onto the timeline no problem. Transitions and effects all look superb on the preview however when rendered they all become completely garbled. Everything else is fine playback is smooth and clear until the timeline bar comes to a transition or clip with an effect that needed rendering for final output. Even rendering the whole timeline reduces all the images to garbled noise.

The clips captured in PAL DV and the project settings are in PAL DV and I render to PAL DV, though nothing is helping?

Hi Nasty,

Will a rendered segment play in windos media player?

You might try RAM-rendering a small section to see if that plays properly...

You might try rendering to another codec like NTSC DV to see if that plays properly....

You might check the preferences to make sure the folders where you render & save files are not on the system drive...

Have you installed any other video apps?

Hi,

I have this problem before and it's due to my firewire cable.

Yes it plays but all transition and effects are garbled.

Yes that play fine in the preview window.

Yes, this works fine. It changed the frame size and squashed the picture vertically a bit but the transition rendered out fine. However I cannot play this back on my camera to print ot tape!

No they aren't.

I have Adobe Premiere 6.0 which works fine. Once transitions have been rendered they can be printed to tape, no problems.

I don;t see how the firewire cable can effect the internal rendering of the transitions and effects. It would be understandable if the monitor showed the garbled images then it could be a cable problem but the preview window shows the garbled images when rendered?!!

Hi Alex,

I guess I would send SoFo an e-mail on this one...

You could always try re-installing Vegas too.

If the RAM-render plays well, but the DV-rendered file (like prerender or render to new track) gets munged, than it sounds like the PAL DV rendering-engine (whatever that is) is the problem.

Can you preview a transition to an external monitor via 1394? If not, then that supports the the DV recompression being a problem...

Does the NTSC DV rendered file play in win media player? If yes, then the problem seems specific to the PAL DV render.

Thanks for your help guys!

I upgraded to 3.0c and found that the problem had been fixed! It had to do with the PAL DV codec or something. Now everything works great and I can print to tape with much success.

I will really enjoy using this software!
