What is the best method to render video and...

I am trying the best method to render my video. It seems like it takes a million years for the files to compress and be able to utilze them when I do a conversion. I mean it is like a littler over a second or 2 per frame. What is the best method for taking video and rendering it to an AVI. what selections should I choose in the Render category. And I am only trying to do a simple movile like 7xx by 4xx. Also can I change my settings to try and put more speed to VV so that it doesn't take so long.

What are your source videos? From your other posts, i'm going to guess you're using DivX or MPEG-2 files. Is this correct?

Christian,
Not sure what your settings are.... but I encode/render MPEG2 files to AVI at real time. Native AVI captures render a third or half real time in my system. Also- depends if you are color correcting or adding an F/X to the video. As you manipulate the video, you increase render times.. Also, keep in mind- rendering speed is driven by your hardware (processor, buss speed, disk throughput, ram...)

For AVI, use the default NTSC DV setting...that gives you 720 x 480. Just what you wanted.

yea but it is not rendering anything near realtime, I mean it is saying that the process is going to take like 15 hours. Crazy.

To let you know exactly what I have done, I have dowloading a Divx movie placed it into VV and want to make it an avi, like the ntsc DV setting that you told me. The rendering takes FOREVER THOUGH.

You didn't give any indication of how powerful your system is. The main requirement for "fast" rendering is raw CPU horsepower. If you're looking for close to real time rendering IF you do much with the file, you're just kidding yourself.

oh crapola

P4 1.8 mhz
768 DDR Ram
40 Gig hardrive
is that ok?

and before I reinstall the Divx codec I can use DVD2Avi to create a divx so I know that the codec works just not in VV
Also I have beeing reading and the WMV codec is supposed to be much better. Now inorder for me to do that I need to get the file I am working with to AVI first and it needs to be done in this century, LOL, what is the best render setting I should do and the fasteds?

A CPU running around 1.2-1.8 Ghz or so as you said is OK. Nothing special by today's standards as far as being a real speedy CPU but plenty fast enough unless you're in a big hurry to get done with rendering. It isn't exact but very roughly if you double the CPU speed you should be able to almost cut the rendering time in half, or within that ballpark everything else being equal.

Again, as a very rough yardstick you should figure about 8 to 1 to render a AVI file using the default DV template not changing any settings if you have a medium speed CPU like I do. Adjust if you have a faster or slower CPU. How much slower or faster the render goes depends greatly on the source file, how many tracks you have, how heavy you use filters, etc.. Again, just a rough guess that is what I average with a 1.66 Ghz AMD CPU with fairly heavy use of FX filters and not too many tracks, rarely more than five.

If you are going to render to multiple file formats, I do... I start rendering to AVI DV, so I can backup on mini DV tape for my camera. Then I start a new project with the file just rendered and then render for a DVD using the MC NTSC template and it zips along at a much faster pase because much of what I changed is already in the file just created and rendering from the project file a second time would take much longer. So that tip can safe you lots of time if you render to more than one file format.

billyboy do you have a yahoo or msn messenger name. mine for both is christian15213, I use yahoo alot so let me know if you have one.

Thanks. and what is a MC NTSC template? is that in the rendering choices?

Please keep in mind, as BillyBoy stated, fast rendering=fast hardware. But not just CPU power... disk throughput, buss speed and ram all play into the equation, along with system set-up. How much is running in the background can affect your rendering time....
Wow..8 to 1 ratio seems slow, but I trust BillyBoy's facts.

I set up my system specifically for a Vegas workstation. Instead of one drive, like your 40 gig, I use 3 drives (all 7200 rpm), one for system and the other 2 as a stripped raid for faster throughput and optimal for video editing. Lots of high quality ram (2 gig), 533 buss speed...

What I have found:
When rendering to AVI: (no F/X) simple cuts, dissolves & a few keys- 1/3 real time
When rendering to MPEG 2 NTSC: (same as above) - real time

With lots of video manipulation- my rendering can be as slow as 3 to 1 ratio depending on what and how much

fast rendering can be achieved---> it's all in the hardware

Nope, I don't use any kind of messaging anymore, main reason is if you enable it then others can pop up annoying SPAM using that same technology. I was getting flooded with those very annoying gray pop up boxes...it got so numerous for me, I needed to turn off the feature.

I try to answer questions here and ususally pop in 4 or 5 times a day, sometimes more. Your best bet if you have a question is ask here in the forum. There are lots of people that help and have great answers.

If you're new check out my web site which links to all the known sites others have put up that focus on Vegas tips, help, etc..

Thanks Deditor. I thing I have found the problem, even though I have a decent system P4 1.7 ghz 768 ddr ram. I am using a Laptop and I can't even thing that my laptop has a high speed harddrive. So to fix that I do have a 2.0 usb support, should I purchase a really good external hardrive and that should solve some of my problem. Also would an extra 256 DDr Ram be that much better or worth saving the 200 hundred bucks? Also when I get the harddrive what should I do to a stripped Raid for faster throughput? <<<LOL, what does that mean?

Oh and one more thing when you make an AVI what codec do you use? And what is the best?

Thannks.

Christian,
I have a laptop at home that I edit V4 on. I purchased a SIIG PCMCIA card for my laptop...about $50 and then an external firewire harddrive. I use QUE 120gig (hard to find now)for the laptop, but Fantom makes some inexpensive drives.(Fantom 80Gig @$189; Iomega makes a 120Gig for $250) Make sure you have a 7200 RPM drive. Forget the raid on the laptop....
You will have to expect longer rendering times on your laptop system, advertised processor speed for laptops---> reality is the mobile units run slower than advertised. Laptop hard drives generally run at 5400 rpm....

The codec I use is V4's. I use the "Video for Windows (.avi)" in the pulldown, template is NTSC DV

My laptop(Dell Inspiron) is a P4 1.7GHz (actually running 1.2 GHz) w/ 768 Ram. (same as yours)... I just rendered a short test: Captured MPEG 2 file and rendered to AVI (as above) no F/X----> render time was 45 seconds for 30 seconds of material or 1.5 ratio
Good luck Christian....
Mike

mike thanks for your input I would really like to email you before I purchase couple of things


thanks for helping me
