Rendering / compression / frame size workflow question
Hi
I am working with Sony Vegas 8 and capturing directly into vegas with my Sony PMW EX1.
My unexperience has got me scratching my head towarrd the end of the workflow.
I am shooting at 1920 X 1080 50i 25fps.
I am then working in a project of this size in Vegas.
I hope I am correct up until here.I then am confused by which stage I should be trying to add my compression.
I want to achieve very high quality video for the web (size is not important to a degree) but am not sure where to reduce file size and frame size.
Should I be rendering my file as an uncompresed .mov, .wmv, .avi at 1920 x 1080 and then putting that file into something like procoder to reduce the frame size and to add compression to the file size.
Or, Should I be adding the compression to the rendering process out of Vegas i.e selecting a custom template and specifying desired frame size and also KBPS??
What is the best file format to use, god there is so many to choose from I dont know which one is the best.
I want to be able to post my videos within my webpage as a flash format – FLV!!
I know this is a long post but I could really do with a few tips.
Thanks in advance
David

Do you own Flash? If not, what converter are you going to use?
For my uploads to the web, I use DivX. I render out to M2T for high definition files and then open up Dr. DivX (a free tool) and drag the M2T file (with audio encoded with it) into Dr. DivX. From here I have a lot of control over the file size and quality.
Once the encode is complete, I then go to http://www.blip.tv and upload my source file (the DivX file) and it will do a transcode to Flash for me. It is not the highest quality flash file but still good. What I like about blip.tv is that it lets you link back to your source file for embeds so you can give your viewer an option of flash or whatever your source file was.
I don’t know if that is what you were looking for or not, but I hope it helps you.

Thanks very much, although it didnt really answew my question. Uploading the final product and encoding to flash is ok.
My issue is at what stage do i add compression and change my frame size so i have different size videos for the user.
Should i render an uncompressed video and then use a compresser to reduce my file size?
Should i render a compressed video and then compress again with another compressor?
Should i render a compressed video and leave it at that and just use an enocing programme to turn into flash?
I own Procoder 3 and Adobe Media Player also.
Thanks

If you have the disk space and procoder can handle uncompressed, then allowing procoder to make the size/compression adjustments may be best. However, you can probably use an M2T file made in Vegas(if HD is your final output, keep it 1920×1080)and be just fine and that will cut down on HDD space usage.Should i render an uncompressed video and then use a compresser to reduce my file size?
You can render to uncompressed, but it may not be worth your time and allocated space when an M2T file or Cineform AVI file will do just fine. But yes, I would let procoder do the compression and frame size reduction if you are going lower than HD resolution-wise. If that is the case, you can probably render out to SD and work with that file instead of HD. Do a comparison (A short 5 second/10 sec. clip of an area with a lot of movement and see what the difference is (if any) in your results.Should i render a compressed video and then compress again with another compressor?
See above.Should i render a compressed video and leave it at that and just use an enocing programme to turn into flash?
