Have just completed editing a 39 minute feature with many tracks in Adobe Premiere Pro CS4 from AVCHD files. It took my 4GB Core2Duo 2.6 GHz computer about 6 hours to export a master copy in MPEG2 1440 x1080i 25 HQ format. The file that is now on my NTFS-formated desktop is so big that I cannot back it up on any of my FAT HDs but that is not a big deal as I can output in lower res or chop it up into bits.
But:-
when I view the exported master copy I find about 5 points where the picture just flickers for a brief moment before continuing.
rogar-BlackEye(DBG? :crybaby:! rogar-Smoke(DBG):??
Now I am trying to detect and fix the cause of this problem. The original footage is ok, so I am guessing the problem must have something to do with the way I am using PP CS4 and/or my computer system.
Have you ever encountered this flicker?
If it is a known problem that has already been discussed please point me to the thread.
Meanwhile I am wondering if the possible reasons for this occasional flicker could be that my computer system is not powerful enough or does not have enough RAM or free disk space available?
Or could it be the program? Previously I had the problem that sometimes the whole PP CS4 interface just wobbled and occasionally crashed. Sometimes the Adobe Media Encoder refused to work at all. But this problem was solved at least for export of smaller (4 minute) movies by removing unused clips and deleting backup copies of the PP file etc.
(2) Maybe my PP CS4 sequence just has too many tracks and/or is too long for either PP CS4 or Adobe Media Encoder or my computer to handle? In which case what alternative do I have apart from upgrading my computer (which I am working on at the moment).
(3) Could the problem be power supply fluctuations during the export or "attention slips" caused by the computer undertaking other tasks at the same time as doing the exporting?
(4) Could the problem be triggered by overload of effects such as placement of subtitles or adjustments to audio tracks on the timeline.
(5) Could too much previewing and/or rendering have damaged the original clips or the instruction set that PP uses to tell the computer where and what to export?
Any advice much appreciated
