I believe internet HD settings are 8Mbps average for 720 and 12Mbps average for 1080. Really, that should be enough for most video unless you have alot of motion and complex subject matter. When you upload to youtube, they will recompress your video again in most cases and it could go back to looking rough but you definately want to upload something that looks good to start with. You can play with changing the Profile from main to high in the “internet” templates and see if it helps.
I just googled “what is a deblocking filter” and got the info instantly. If you don’t understand the technical details behind it and it doesn’t make a visiable difference then who cares? You certainly can’t expect people here to bring you up to speed on h.264 encoding when you can read plenty of well written informative articles that are already out there.
From what you have said, it sounds like the $100 difference would be worth it to you. The two extra physical cores on the i7 will be invaluable if you end up rendering hours of video.

There’s also the possibility that it is being handled differently by whatever program you are using to play it back. Put the rendered mp3 clip back in vegas and see if the audio levels are the same as the project it came from.

Bumping the bitrate is usually the solution to poor quality renders with pixelation etc. Your processor meets the requirements for Sony Vegas and it does render so… there you go. It does work…. I don’t know if I would recomend buying an i5. Although it would perform better than your current core 2, saving the money until you can pick up an i7 would be smarter.
As far as the deblocking filter: I would imagine Google will help you there.

Yes, that is the best way without the velocity envelope. When you slow your 240fps footage to 1/4 speed, you will be at 60fps so obviously render out to a 60fps intermediary then bring it back in and slow it more if needed.
If you are doing everything else right and rendering to a high quality intermediate codec, there should be no visiable loss of quality.

Hey bob. You will probably want to look up long GOP and read up on that but basically it is a compression format where every frame of video is not a whole frame. Mpeg and H.264 are long GOP. DV is actually not, every frame (Besides the interlacing issue) is a whole frame. You will find DV as a render option under “Video for windows (.avi)”
I would recomend installing the free cineform codec from the gopro site for when you start getting more into this if you need an intermediate codec. Google the gorpo cineform thing too. You don’t really need it for DV though.

To tackle your original question of VBR vs CBR, that would depend on what you think of as optimal. If you mean optimal quality, then CBR is probabl;y going to be better if you don’t care about file size. If you are concerned about file size, then especialy with a talking head on a static bland background, VBR will be VERY efficient file size wise. If you mean optimal encoding time wise, then obviously CBR is much quicker than 2-pass Vbr.
I will typically use CBR if I am doing a test viewing on my TV or something and then 2-pass VBR if the final render is being uploaded or burned to keep file size down.

Shoot, if that’s the case then just give them the 4:2:2 Mpeg and be done with it.

He meant what part of the country are you living in.

I’m not sure if it’s what you mean exactly but you can have two Vegas projects open on your computer at the same time and copy and paste any tracks from one to the other.

You have to do it by eye to whatever looks right to you. Those old film ameras were usually either Hand crancked or run by a spring. Two of the same camera model could run at different speeds.
Can you describe the flicker? Try right clicking the clip on the timeline, selecting properties and checking dissable resample.
I absoultely hate Vegas’ atempt to resample missing frames when I’m playing with velocity or even say dropping 60p footage on a 24p timeline. Or I should say that I hate that resampling appears to be set to on by default and “smart” resample isn’t all that smart.
