    10 hour export time for 2 minute video

    tim66312 Community Member

      Hi,

       

      I am using Premiere Pro CS3 with Windows Vista.

      My laptop has 50gb of free disk space and 4gb of memory.

       

      I have recently purchased a new Cannon camera that records video in Mov with res 1920x1080.

       

      I have a six minute video clip that is 860mb in its original format. I am attempting to resize the video to 1280x720 whilst also altering the levels and changing the speed/duration to 220%. With this alteration to the speed the clips length is reduced to around 2 or 3 minutes long. I wish to export the video as a Mov, keeping it in its original format.

       

      When attempting to render by hitting enter on the clip, or skipping straight to exporting, I recieve an estimated time of 10 hours to complete. The exportation seems to be going ahead but only by 1 frame every 10 or 20 seconds.

       

      Would really appreciate any tips with where i'm going wrong with this. I'm fairly inexpiernced with premiere pro and therefore do not know if this is a problem with settings I am using or just with my computer.

       

      Thanks Very Much

      Tim

          1st - the average laptop is going to be VERY slow for video editing (more below)

          - go to http://ppbm5.com/ and check the laptop results to "guesstimate" where your brand/model would place

           

          2nd - even a fast computer may be slow, depending on the video file and with "combined" effects

           

          More on why the "average" laptop is slow... plus, of course, the average laptop has a 5400rpm drive instead of 7200rpm

           

          Trying to use only ONE Hard Drive for Video Editing

          .

          You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to various parts of the hard drive to do Windows housekeeping or to load program segments for various functions

          .

          Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work

          .

          You as a person cannot do both at the same time with the same hand

          .

          A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for EASY video editing

          .

          You need AT LEAST two hard drives (separate drives, never a partition http://forums.adobe.com/thread/650708 for more) with Windows (or Mac OS) and software on your boot drive, and video files on a 2nd drive so the boot drive is not slowed down by trying to do everything

          .

          Partition = Crash http://forums.adobe.com/thread/957286

          .

          I find that the three drives I use work very well for me, for editing AVCHD video... some people use a 4th drive, so video INPUT files are on drive three and all OUTPUT files are on drive four... I only bought a mid-tower case instead of a full tower case (my bad... but had to fit in the space available on my office desk!) so I use the three drives that will fit

          .

          Depending on your exact hardware (motherboard brand & model AND USB2 enclosure brand & model AND external hard drive brand & model) AND the type of video file, you may... or may NOT... be able to use an external USB2 hard drive for SD (Standard Definition) video editing

          .

          .

          A USB3 hard drive connected to a motherboard with USB3 is supposed to be fast enough for video editing (I don't have such, so don't know) but eSata DOES have a fast enough data transfer for video editing... I have not used the eSata hardware below... for reference only, YMMV and all the usual disclaimers

            On your system, this sounds pretty normal.

              you wont like this solution maybe, but at least you can try it...

               

              start the export and leave computer on, and go to bed...in the morning see what you got ??

               

               

               

              dont laugh... years ago i had a 3d program that took me 10 hours to export one single frame from the "scene" I created in the program...and I did that at night while I slept.

              This was with a pc when the cpu speed was a blazing 1.33 mhz and memory was restricted to about 512 kb, with extended ( or expanded ? ) memory of about 1 megabyte ??  Years ago...

               

              But look at how cool it looks !

              and I had nice dreams while I slept...how cool is THAT ?

                Thanks for all the tips, a lot of stuff to look in to, great advice.

                 

                Just one more question.. Last night I attempted to export just the original video as a Mov and reduced the size to 630x360 with no other changes. The export took 2 hours and strangely created a file size of 7.8gb. No idea what went wrong here but am very confused as to how a video of a smaller resolution can be 10x the file size.

                  MOV (or AVI or any other file name extension) is but a "wrapper" that may contain any of a number of CODECS

                   

                  A codec may be highly compressed to not take up a lot of space, or not so compressed... when creating a new file, YOU select the codec that goes inside the MOV wrapper, and therefore you control the compression

                  Report back with the codec details of your file, use the programs below... a screen shot works well to SHOW people what you are doing

                    am very confused as to how a video of a smaller resolution can be 10x the file size.

                     

                    Because resolution has nothing to do with file size.

                     

                    File size is affected by only two things, duration and bitrate.  How many bits per second x how many seconds = file size.
