[fernand eythimiades] “I need the best image quality (i dont care about the sound).”
Your audience does! Audio is 60% of the video experience. You can watch a bad video with good audio but most people won’t watch a good video with bad audio. So as a new editor, you need to understand how important audio is.
[fernand eythimiades] “I record PAL 24 ftp”
There is no such thing as PAL 24p. PAL is 25 fps. Also PAL doesn’t tell us anything about what format you are shooting. Is it SD 720×576? HD 1280×720? HD 1920×1080? These are all valid PAL formats.
[fernand eythimiades] “1. What do i choose for “project properties” ?(vegas)”
Set your project to match your source (whatever that is, you didn’t tell us). You can use the Match Media button in project properties.

[fernand eythimiades] “2. What do i choose for “render as” ?(vegas)”
Again, without knowing if your video is SD or HD it’s hard to say. Once you determine this and select the proper template, you’ll need to change the frame rate of the template to 24.0000 (Film). That’s what you want to use for film transfer. I assume the company that is doing the transfer will tell you what format they accept.
[fernand eythimiades] “1.which one is the best format for “color corretion”? (adobe)”
I like to use the CineForm codec for working with After Effects. You will have to buy it, but it is specifically designed for intermediate transfers like this.
[fernand eythimiades] “2.Do i have to “color correct” , after or before the render?”
If you are “color correcting” (i.e., making cameras match, fixing white balance, etc.) you might want to do that on the source footage before editing. If you are “color grading” (i.e., changing he “look” of scenes to match a mood) you could render scenes or of Vegas, color correct in AE, and then bring them back into Vegas for the final render. Or you could render the whole movie and color grade in AE and render the final movie from AE. It depends on how you like to work.
[fernand eythimiades] “3.Which one is the best format for export?”
I would use CineForm to export from AE as well.
[fernand eythimiades] “As you can see iam pretty confused about editing, i would like to ask somebody that has the knowledge to help me understand the whole progress(workflow) of color correcting and editing.”
Why are you using After Effects at all? Vegas Pro has very good color correction tools and there will be no need to render at all. I don’t understand why you think you need AE to color correct. Get the Magic Bullet Looks plug-in for Vegas Pro and you’ll have an incredible color grading tool with no need for all this rendering.
