Flushing DV Transcode Buffer???

[tcarbo]

What the heck is that? I'm getting this while capturing from VHS using ULEAD's MPEG Codec? The capture stops while a window pops up with the message "DV Transcoding.... Flushing DV Transcode buffer". In the meantime my source (VCR) continues playing while the capturing stops. What is this and how can I get rid of it? Is there a setting I can tweak?? ULEAD support sucks in USA. Can't get any response at all!

This is a well-known phenomenon, but it isn't a problem. Unfortunately, you have not filled in your details, as requested in the "Please read this before posting..." thread, nor do you tell us your settings, so I cannot have a clue why it is happening in your case.

Basically, it means that your system does not have enough resources for what you are trying to do. You are trying to copy a presumably DV file and to simultaneously transcode it to MPEG-2 in real time. This is not easy and it fails because of one of the following or a combination of two or more of them:
1. Your CPU is too slow
2. You have insufficient RAM
3. Your motherboard chipset is slow
4. Your HDD is not DMA enabled or is external (USB or IEEE-1394) and cannot follow the speed
5. You have set the MPEG-2 settings too high
6. You have too many other apps/utilities etc. working in the background.

In other words, to do it successfully, you need to have everything just so. If you must transcode, make sure your transcoding settings are modest (say, 4500 kbit/s CBR for video).

That having been said, it is never a good idea to transcode: you would do much better to transfer your DV to AVI in VCapture, do any editing you require and only then encode to MPEG-2. This will allow you to obtain much better quality, as you have no constraints with having to do it in real time, even if you have a low horsepower computer. However, point 6., above is important for ALL video work.

Devil. Thanks for the reply and your great tips. I will certainly look into what you suggested. Here are my settings:

1. Your CPU is too slow
- Not the problem: Intel P4 3.2GHz

2. You have insufficient RAM
- Could be the problem: 1 GB DDR 400
(purchasing another 1 GB per your tip)

3. Your motherboard chipset is slow
- Not the case

4. Your HDD is not DMA enabled or is external (USB or IEEE-1394) and cannot follow the speed
- Not the problem: Is DMA enabled. Also, capturing to GRAID 320GB
with a Firewire 800 controller.

5. You have set the MPEG-2 settings too high
- Could be. the problem. I have quality set to 100% with a variable
rate set to 6000 kbit/s.
(I will try playing with these settings per your tip).

6. You have too many other apps/utilities etc. working in the background.
- Not the problem: Always disable antivirus, Adaware, etc. from
running in background.

7.Do you carees your pc while capturing ?
8.Do you smoke while transcoding ?

...just for fun

OK, it looks like 5. may be the problem. Jack down the quality setting to 80 and try CBR: 6000 kbit/s should be OK.
