  Kona LHe output garbage frame when there’s empty gap on timeline

  Posted by Ben Cheng on December 22, 2005 at 3:47 pm

  Anybody experience this ?

  – Problem :
  When there’s empty gap on timeline, the Kona LHe video output displays a flickering garbage frame

  Once there’s video media, the playback is fine

  If stop & play from empty gap, it will output the last frame of video when stopped, flickering

  Affects only “PAL 8bit to DV” media captured through LHe

  8bit Uncompressed media is fine

  Sequence presets match the media codec

  Tried using different “video playback device” & no affect

  Tried “refresh audio/video devices” & no affect

  – Workaround :
  Insert a slug in the empty gap

  – System Config :
  Apple PM G5 Quad 2.5Ghz
  ATTO UL5D – Slot 3
  AJA Kona LHe – Slot 4
  4GB RAM
  Huge U320R-1200GB – RAID/2k

  OS X 10.4.3
  QT 7.0.3
  ATTO 3.5.0
  FCP 5.0.3
  AJA 1.1.6

  You should always have a slug in an empty gap. I see that here occassionaly in DVCPro HD timelines where I’ll get garbage in gaps until a Slug gets dropped in.

  You can probably also insert an empty Title in the gap to get rid of the garbage.

  Absolutely confirmed here. I was about to post the same problem. Of course, it doesn’t affect your final output – it’s a dsiplay issue only but it should be fixed.

  Hi

  Thanks for your advice & replies

  May I know if you experience the garbage issue when a filter is applied on the clip ? e.g color correction ?

  Once the color correction filter is applied, the output becomes garbage, hence unable to use that

  Wonder if anyone else has the same issue & found a solution ?

  As I mentioned: For me it was only a monitoring thing, albeit a damn annoying one! This was because I transcoded the timeline to MPEG2. Had I been outputing the timeline to DigiBeta, I don’t know if the problem would have gone with it. I haven’t tested that yet. If it does, then we got a bad problem here – Aja?
