Help with Error Message"Flushing DV Transcode Buffer" in Ulead Mo

[walpoo]

Hello, I am using Ulead Movie studio 9 to capture off Canon Digicam. I have Ulead set at 720x576 DVD VBR. Machine is a 2.8 celeron, 512MB ram, Windows XP SP2, IEEE1394 I/face card. The "frames in buffer" are being flushed. Capture stops during this, then resumes. Does this error mean I have settings too high or machine too slow. All help welcome. Good health to all, Wayne

First consider capture to DV format instead of attempting realtime MPeg capture. Under capture select DV format not DVD or other. You then edit in DV format and convert to DVD (MPeg2) after editing.

Selecting DVD causes the program to attempt MPeg2 encoding capture on the fly. The quality will be lower with this method. "Flushing DV Transcode Buffer" happens when the CPU can't keep up and the data buffer fills up.

Your CPU and RAM are adequate for realtime encoding but your average bitrate is probably set too low. Try 8000Kb/s ave and see if that works. If so reduce until the buffer flushing occurs and then go back up higher to allow a safety margin. I have a 2.4GHz Celeron with 768MB RAM that runs out of power below 7000Kb/s. A 2.8GHz P4 with 1GB RAM extends that down to around 6400Kb/s.

A good warning indication that flushing will occur is a climbing "Page File Usage History" line under XP Task Manager Performance.

Hi, Thanks for prompt and helpful response. I see in the DV format, you have a couple (maybe) options. If I read correctly, you convert to MPEG (DVD) in Ulead and change the settings (8000kb/s etc) there.

I am capturing some Historic Steam train footage now on the other computer, and the sound seems crisper and the image a lot sharper. No buffer problems either.

Have only had the Digicam a couple of weeks, and was so used to capturing VHS tapes on an analogue capture card. This digital stuff looks like top shelf gear.

Again, thanks. Wayne

So, camcorder transfers (from tape or pass-through) will have top quality when DV is chosen under the "Capture Format". It will create a 13.5GB/hr capture file in DV-AVI format.

Selecting "DVD" under "Capture Format" will force an attempt at realtime VBR MPeg2 encoding. This will be lower quality than non-realtime MPeg2 encoding that is done when you use "Share" , "Create Disc" and "DVD" format after editing.

So for top quality, "capture" to DV format. Edit the DV-AVI file, then use "Share" , "Create Disc" and "DVD" format after editing

Hello again and thanks, I noticed the AVI format files are large in size, and this obviously gives one a high quality image. My "new" captures to date are very impressive - both audio and video wise.

All I need now is a good technique to edit my audio (mainly overdub un necessary background noise). At moment I extract audio with ACE DVD audio extractor, edit in Adobe Audition, then rejoin in Mainconcept. Cumbersome but seems to work (although I haven't tried this on any new captures yet).

Take care, Wayne
