When rendering goes bad: request for help

[anniehow.livejournal.com]

Hello, I've just finished my first vid with Vegas 9 and I've found myself hitting a wall. I've tried rendering it in several formats (avi, mp4, wmv) but the problem remains: it will not render the clips I've sped up.

I've altered the time flow of a grand total of six clips within the vid, slowed down two and sped up four; the program rendered the two slowed down ones just fine, but the sped up ones just show up as black. I tried selectively rendering them (shows black), I've tried selectively pre-rendering (shows up black). If I check it out on the timeline it looks fine: all the frames are there, the program recognises the clip, etc. but it just won't give me the finished product!

Help, please? I've exhausted my limited resources already, I don't know what else to do!

Never seen this happen, but I wonder... What format / codec are you source files? I'm guessing MPEG, Divx, Xvid, or something like that? These kinds of codecs only store every-few frames as complete images and crunch some numbers to fill in the gaps. Changing the playback rate can get confusing for an encoder.

One thing you can try, if you want to keep resampling on, is render out the problem sections -- without the change in playback rate -- to AVI using a good quality codec like DV, Lagarith, or Huffyuv. Replace the problem sections with these new files, apply your playback rate changes, and try rendering the whole thing again.

Thank you for your advice. I don't actually need/crave a particularly good quality so disabling the resample's ok, but I'll keep this in mind for the future :-D
