Video Track FX…where to put them? +
Hello all. Ive been having trouble rendering in vegas 9.0d lately and im thinking that its because of a Track fx that I started using. Its called “Glint”. I set it on certain clips in my timeline not all of them. Render results have varied from video going black about 45 seconds into video but the audio is still intact and going…what used to render in about 1.5 hours now takes 10 HOURS!!
When i open a project sometimes the video preview is blank. I upgraded to 9.0d and downgraded quicktime back to 7.6. so now its like sometimes I can get video in the preview and sometimes I cant. it’ll work if I minimize vegas and then bring it back up. Kinda weird.So I have a couple questions:
1. Does it matter where i put the video track fx? Would it save my pc memory/power if i set each individual clip in the timeline with its own fx or would it be better to just set the fx on the actually track??
2. Should I save the footage im using for a project on an external firewire hard drive, or on my PCs hard drive to maybe help get the videos loaded up faster?3. What would be the best render settings to start from? I like the quality of Mt2s, MP4, and WMV but that crashed at %1 whenever i try to render in that format.
Im also thinkin that my PC isnt built for what im trying to do.
I only have 2 gigs of ram, AMD Athlon 64 Dual Core Processor 4000+ 2.10 Ghz. Im running Windows 7 64bit.
Im using HD 1920×1080 footage from a Canon 7d.Any help would be greatly appreciated
thanks

I don’t think it matters if you put an effect on each event or if you place it on the track as long as you don’t do both and process it twice without wanting that. Glint is *extremely* CPU intensive and I can’t imagine using it for all of your clips. There may be a more CPU friendly way to get the effect you are looking for.
If you are working with HD and you’re not using a 2.8Ghz Dual Core with 4GB or memory or a QuadCore with 8GB of memory, you’re in for some slow renders. At 2.1GHz your Dual Core is below Sony recommended specs and with only 2GB of memory, it doesn’t leave a lot of memory for each core to use. More memory or more cores and more memory, would definitely help.
Note that Sony recommends:
Multicore or multiprocessor CPU recommended for HD
2.8 GHz recommended for HDV and AVCHDSo your 2.1 Ghz processor is not up to spec for HD editing (and that’s without throwing CPU hogs like Glint on your video).

ahhh thanks for enlightening me…so just adding 2 or 4 more gigs of ram wont do me any justice without the cpu power?

Adding more RAM will help. You should have 2GB per CPU so the optimal setup for your Dual Core is 4GB of RAM but you really need more cores to make rendering go faster. It is close to linear so two more cores will almost half your rendering time.

okay so I used a computer that has and AMD Atholon IIX2 250 Processor 3.00 GHz with 4GB of RAM…still got pretty much the same results i did on my computer with less power. My rendered file is perfectly fine up until about 3 minutes into the video, then the screen goes blank but the audio is still going. My video is only 4:21.

Have you considered purchasing Cineform NeoScene? It specifically supports the Cannon 7d and fixes a lot of these issues with playback rate and rendering. I would download the trial and see if it helps. If you decide to purchase it, I would recommend buying it from VideoGuys.com. They are not only a sponsor here at the Cow but they are cheaper than the Coneform site at only $99 USD.

So i finally got a complete render using Cineform NeoScene…but the .avi video quality is not as sharp as my original 7d 1920×1080 HD footage. Do i have my prefs set on the wrong settings possibly? Or is getting the identical quality pretty much impossible using Neoscene?

I can’t say because I’ve never seen raw footage from the 7D. My HDV footage from my Sony HVR-Z1U looks the same with Cineform. There are setting that you can tweak to get better quality. In the Custom render settings you can use the Configure… button to change the encoding quality from Medium HD to High HD. See if that helps.
