          That is everybody here. You probably mean only those people with hardware accelerated MPE and exclude all that use software MPE?

           

          MP4 is just a container, so what flavor are you talking about? If you mean AVCHD, yes.

           

          Export to MPEG2 has been available for many versions. Rendering is not necessary for export, only for preview. You still need to encode however.

            To reinforce what Harm is saying:

             

            "I’ve noticed a lot of people—the vast majority, really—using the term  ‘Mercury’ or ‘Mercury playback engine’ as if it refers specifically to  CUDA processing. Not true. The term ‘Mercury playback engine’ refers to a  whole set of performance improvements in Premiere Pro CS5, including  the port to a 64-bit application, the multi-threaded nature of the  application, and the use of CUDA on the GPU to accelerate some things.  Anyone using Premiere Pro CS5 is getting all but one of these  advantages; people with certified CUDA cards are getting one additional advantage."

              Iwas hearing about this video card call quadro fx 4800. Does it really work as they said. Here I am working with a lot of mp4 file. I can edit them in the Premire cs5 but I have to render which is time consuming. Before I buy this card I just want to know if you can edit this mp4 file without rendering and export them to mpeg2 format on the fly. Thanks

                MP4 is a wrapper... what CODEC is inside that file?

                  Oh ok just to make it clear, I am new to Adobe Premiere CS5. I've been a final cut for years but I was introduce to premiere by a friend and love it. I know you guy probably think why  don't I work with dv format or quick time movie. Well I do a lot of episodes and they eat up your hard drives plus I've been recording them from a dvd player just to get that subtitle. Now I can rip from dvd with subtitle and the only software that do a perfect job is HandBrake. I bought DVDxDVD and ImTOO DVD Ripper Ultimate and they don't even come close to HandBrake. But HandBrake only produce mp4 file and mkv file. I like the mp4 file coz its very good quality and small size. Now it comes to editing mp4 files. Final cut can't even play mp4 file. Adobe Premiere cs5 is the choice not that I can play mp4 files on the timeline and edit them also. Ok thats very good, but I have to encode the sequence to mpeg2 format and here comes the problem. Now I have to render them first and then encode to mpeg2. I was wonder if the Quadro FX 4800 card can save me times. Please anybody that have this card, would you please try to import mp4 to the timeline and encode them to mpeg2 for me. If you can do this without rendering, please let me know and I would appreciate it very much.

                    The graphics card has nothing to do with encoding or decoding. The graphics card will speed up the processing of some effects, scaling, deinterlacing, and blending modes.

                      See #1. Yes you can do that without rendering, but I'm repeating myself here.

                        Thanks you very much Todd. I will check it out. One more question.

                        Does that mean when you put the mp4( mpeg-4 , ffmpeg) on the timeline it's not red?

                          That is actually not a legal use of the software.  Unless, of course, you have permission from the copyright owner of the DVD content to be reediting the material.

                            There's a yellow line above the clip in the sequence that I just created from an .mp4 file.

                                    With CS4 or even before that, when we did not have the luxury of hardware MPE accelerated renders, it was not uncommon to not use rendering at all. We just left all the red lines in our timeline as such. There was no sense to render the timeline, because we did not use it anyway on export. Now in CS5 it is such a small effort and just a few seconds, things may have changed in the sense that more people want to have RT previews, so they render their timeline, but still it has no impact on export.

                                      I fell ya. I only really render during work when playback grinds to jigs and jags where I still have to cut on beat etc. And even when it jigs and jags and I have nothing important doing there, I leave it alone. FCP is set to auto render all open sequences 15 minutes of away time so when I go out for lunch or whatever I come back to a good to go timeline. The thing is also that we still go to tape so rendering is that final step.

                                        That is not called Rendering, but encoding or transcoding.

                                         

                                        In a number of cases it is important to use the correct terminology, like here. It is incorrect to say: "While sailing my car..." or "While flying my boat..."

                                        One can avoid misunderstandings and miscommunication by using the proper terminology. OTOH, it may well be a shortcoming of the english language:

                                         

                                        There is no egg in eggplant nor ham in hamburger; neither apple nor pine in pineapple. English muffins weren't invented in England nor French fries in France. Sweetmeats are candies while sweetbreads, which aren't sweet, are meat. Quicksand works slowly, boxing rings are square and a guinea pig is neither from Guinea nor is it a pig. Why is it that writers write but fingers don't fing, grocers don't groce and hammers don't ham?

                                        If the plural of tooth is teeth, why isn't the plural of booth beeth? One goose, 2 geese. So one moose, 2 meese? Doesn't it seem crazy that you can make amends but not one amend. If you have a bunch of odds and ends and get rid of all but one of them, what do you call the thing left? Is it an odd, or an end?

                                        If teachers taught, why didn't preachers praught? If a vegetarian eats vegetables, what does a humanitarian eat? In what language do people recite at a play and play at a recital? Ship by truck and send cargo by ship? Have noses that run and feet that smell? Park in a driveway and drive on a parkway?

                                        How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? You have to marvel at the unique lunacy of a language in which your house can burn up as it burns down, in which you fill in a form by filling it out and in which an alarm goes off by going on.

                                        English was invented by people, not computers, and it reflects the creativity of the human race, which, of course, is not a race at all. That is why, when the stars are out, they are visible, but when the lights are out, they are invisible.

                                              Sorry my language Harm. I meant encoding to mpeg-2. You correct on that.  Ok here is another question. If you you see red on the timeline, does that mean you have to render it before encoding or just encode it any way.

                                                  To restate Harm's answer another way... Nyet. You do NOT have to render to encode to MPEG-2.

                                                    I hope this card is worth it coz it's very expensive. I will let you guys know after this.

                                                            I picked up one of the last GTX285 cards available from Newegg last month... made by Gigabyte. When I did my research, there really wasn't a HUGE difference in performance between any of the GTX level cards, primarily because your bottleneck will probably be your hard drives... I paid $250(?) for the GTX285, and the 470 (which I was also considering) was close to $400... I'm not sure what the current prices are for that card, but a simple search on Newegg should result in some answers for you. ;-)

                                                              They only work with mac pro 3,1 version. So now I'm stuck. I have to change my system first before I can go on with the cards. Please tell me is this true.

Now I can't go on untless I sell my old mac and buy the newer one. I just dont know why mac is so anal about this. I should have known from the begining. I was so into mac and believed that anything that have to do with videos and sounds you have to use mac and they are the best. Now I realised that most of you guys are using pc and you guys are pro in the video field. I started to feel odd. May be I don't need the newer mac pro after all. What I need is to change from mac to pc just for to take advantage of the adobe premiere mercury play back engine. Thanks you guys!
