    4 minute video looks fine-8minute video is choppy

    McBuff Level 1

      I've been trying to export my project. It's an 8 and half minute project. . .one segment. If I export 3 minutes sections. . .each section is beautiful and smooth. If I try to export the whole thing. . .it is choppy. . .very bad. . .like riding on a bumpy road of gravel. I've tried everything. . .every setting. . .turned off virus software. . . .everything. . same thing. . .3 minute segments. . beautiful. . . .which means I have three separate videos. . no good. . . .if I try to export all 8 minutes. . .CHOPPY. . . .what am I missing?

          No idea. You haven't told us anything about your system, your source footage, your sequence settings, your export settings, how you're playing back the exported video, etc. We don't even know what version of Premiere Pro you're using.

            But has anyone ever heard of this problem. . . .if I cut the project into three and export each segment. . .each one looks fine and runs smooth. . .this would tend to eliminate a lot of possibilities don't you think?. . .I mean 4 minutes and its beautiful. . .I have no problem. ..as long as my project is 5 minutes or less. . . . .if I export the entire eight minutes. . .its choppy. . .It would seem to me all the info about my system, versions. .settings. . . export settings etc. . .are not relelvent yet to the question. .I've changed my setting so many times I've lost court. . .I even turned off my virus software thinking it might be that. . .. . .nothing works believe me. . . . . . I'm asking if anyone has heard of a similar problem and it would seem to be a very specific answer. 4 minutes ok. . .8 minutes choppy. . I've looked thru many forums and haven't found anybody with this problem. . .either its all choppy or its fine. . . .not fine AND choppy.. . .

              Just a guess but maybe your system is heating up on longer video.

               

              Do a test and watch the temps while you are encoding.

               

              Also how many Hard Drives do you have ?

                I have one hard drive.. . .but here's another aspect to the mystery. . . .I uploaded the choppy video to YouTube. . .it runs smoothly and looks absolutely normal. . .even when I bring it up to full screen. . .HUH??!!

                  >one hard drive

                   

                  Below minimum specification... you need at least one drive for boot and all software, and a separate 7200rpm physical drive (never a partition) for video files

                   

                  My 3 hard drives are configured as...

                  1 - 320Gig Boot for Win7 64bit Pro and all program installs

                  2 - 320Gig data for Win7 swap file and video project files

                  When I create a project on #2 drive, the various work files follow,

                  so my boot drive is not used for the media cache folder and files

                  3 - 1Terabyte data for all video files... input & output files (*)

                  (*) for 4 drives, drive 3 all source files & drive 4 all output files

                  .

                  Search Microsoft to find out how to redirect your Windows swap file

                  http://search.microsoft.com/search.aspx?mkt=en-US&setlang=en-US

                  .

                  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?tstart=0 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

                  .

                  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 Dock below... for reference only, YMMV and all the usual disclaimers

                    The last Hard Drive that died on me started by playing Video choppy.  Everything else was fine but video.

                     

                    Make sure you have a backup just incase.

                      I just check the heat. . .it's red hot. . after 30 seconds of rendering!. . . .I'm going to have to figure out everything I need to do in order to produce videos and not burn up my system . ..

                        Video editing, like high end gaming, is the most stressful thing you can do with a computer

                         

                        You need to make sure you have LOTS of case fans (and that everything is CLEAN with no dust buildup) to draw outside air into the computer and push the warmed air out the back vents

                         

                        If your case does not have a side vent, with a fan to blow outside air directly onto the motherboard, you need a different case

                         

                        The stock CPU cooler works for general computing... not so much for video editing... especially during rendering, which causes the CPU to create a LOT of heat that the CPU cooler needs to be able to draw away

                         

                        If there is a custom computer builder in your area, go look at what is built for high end gaming (or video, if the builder does such machines) to get a general idea of the cooling requirements

                          <sigh>

                           

                          This has nothing to do with the hard drive setup, or the temperature, or anything hardware related. You still did not answer the question I asked about how you were reviewing/watching the clip locally where it exhibited the choppiness. The fact that you were able to upload the clip to YouTube and it plays back fine there suggests a local playback issue--if it were baked into the file, it would show on YouTube just the same as it does on your machine locally. So, while this is very likely caused by export from Pr, but before we go down that road, you need to confirm my suspicions.

                           

                          PS: Yes, I've had this issue, too. I'm pretty sure I know what the problem is--or more specifically, how to solve it. But I'm not going to guess until I get the information I requested...

                            I played the clip back on Windows Media Player. I did install a utility to measure the temp. .and when I was rendering. . the tempurature went sky high. . .

                            Here's some more info. . .sorry if I appear confused . . .its not an appearance. . its genuine (I'm a novice at this.. . .as if that is not obvious by now!)

                              Here's another thought. . .the video had several still photos in the sequence. .. does photo resolution matter when inserting a photo into a video sequence? For example. . a high res photo should be optimized for the web. . .would this be similar for video production?

                                If that is CPU temp, you need better cooling FAST or you risk killing your computer's brain

                                  Thanks JT. . .yep its the Intel i 7quad core temp. . . I got a line into ZT now asking them what gives with that. . .this system was touted as great for video editing and high end graphics work. . . it runs cool otherwise. . .but if I try to render a video. . .it goes hot in about 40 seconds.
