Hello everyone, newbie here. I found out that as I press the enter key while I'm working in Premiere Pro CS5, it "renders" my footage. I'd like to know what rendering is and, above all, do I need to "render the work area" before exporting my project on DVD? My footage isn't so short, so the rendering will last hours.

If you're getting smooth playback without rendering then you probably don't need to.

If you're getting choppy playback when f/x are applied and or a client is watching
you want it smooth...so you render.

If you have a feature length movie and have difficulty getting it exported
in a timely manor, then you can set the sequence for example to use the prores (mac only)
codec and render sections until the entire sequence is rendered, then do an export
very quickly by selecting "use render files."

Hi....


when you assemble material together on a timeline, and any kind of effect is used or images are somehow layered....

the computer will attempt assemble and play back the material as close to as real time as pssoible.

Sometimes the material, as you have it arranged to layered is too complex for the computer to assemble on the fly...

rendering takes the area and calculates a single movie that it keeps on disk. Assuming no changes are made to the area in question, the the computer goes to play back that area....it will use the single "rendered" (already calculated clip...which it knows where it's stored, butyou don't see on the timleine) as opposed to trying to put it all together at time of playback.

Is it necessary...? Really depends on the complexity of what you are doing and whether the computer can assemble it in real time smoothly or not (at the resultion of playback you are requesting).

PPro tries to anticipate and clue you in by placing different color bars over areas of the timeline to indicate how well it might do at playing it back.

The meaning of these changed a bit over time and I can't remember back to CS5 what they were.

But this should give a general idea of what's going on.

to my knowledge:

yellow stripe = it might play it smooth

red stripe = will probably not play smooth

green stripe = will absolutely play smooth

I very rarely EVER render anything in the timeline. Even clips with red above usually play smooth for me, so I complete my edits and then Export to format of choice.

Thanks
