problems with OUTPUTing video

Apr 25, 2013 7:15 PM

having problems with OUTPUTing video in Premiere and After effects, with drop frames and  'judderly footage'  THIS IS not on the original footage , but can be seen even when rendering is in progress. ( It is also a 'random problem . so to does not always happen in the same spot /place on the timeline/footage.

The footage has been used in previous version  CS 4 with out any problems.

footage  mpeg 4 - avi-s output as mpeg 2



NEW PC edit suite with 2 raid drives each with 3 partitions. old edit suite had 4 separate drives ?? could it be a problem with reading drives  AS I have also noticed the render ,just for a moment, stops/pauses then continues..... this  VERY short stop also appears in the final output.


IT's very wysiwyg   ..I'm not outputting to tape  .it is outputting as a  media file mpeg 2, Yet still has the above problems of visual stops/jerks and drop frames .


some of it looks like interlacing problems................but all is progressive footage ( that's not the prob ,, it is the only way  I can describe it ).


have changed/added different CODECs,  tried out put as different formats , converting input footage to different formats .the footage plays


'O.K' in  other video players = vo player  . wmp. QT. and is o.k  on different  computer using  avid, both  on a  timeline  and play back.

    What are the details of you media, your sequence, and your export settings?

    It is a very bad idea to use partitions. They cause a lot of wear-and-tear, reduce performance significantly and put a heavy burden on the system.


    Have you been in the Navy? Why do something the easy way, when there is a much more complicated way seems to be the Navy way.


    You need PAL SD material, so use MPEG2-DVD to export. Keep everything PAL, so 0 - 255 RGB range, 25 fps, 720 x 576 resolution and turn on MRQ. Do not modify anything else, unless you KNOW what you are doing.

    MRQ = Maximum Render Quality.


    Good luck,

    It sounds more like the cache is corrupted and the files may have dropped frames that then get duplicated.

    Try to clean the Cache via the preferences Menu under "Media & Disk Cache" > Conformed Media Cache > "Clean Database and Cache" then restart After Effects. If you see any activity of the cache being rebuilt, usually an orange progress bar, leave it until its done rebuilding the cache files. Then export.


    I wouldn't recommend using Partitions for Video work.

    Check out this link for multiple links on how to build and optimize a system.


    I'd run a HDD read/write speed test (there are IO Cards that supply a Disk Speed Test Utility) to check the actual speed of the disks.


    Partitions are bad for video which needs high speed read/write datarates. Espcially if you are running the OS from the same Physcial drive as the content...


    Good Luck. JB
