Difference between Type 1 & Type 2 AVI

[Fairhope]

I've been using Pinnacle Studio 9 for capture and have noticed some dropped frames. The resulting .avi file has audio out of sync. In reviewing many comments on this forum, most people thing the out of sync audio is from dropped frames.

I was going to give WinDV a try for capture, using the pass-thru on my digital camcorder.

My question is in regards to WinDV's configuration of Type 1 or Type 2 AVI. What is the difference? It mentions something about Type 2 being compatible with VFW drivers.

I have the XP os. Can anyone give me a quick reference guide as to the differences between these two types and reasons why one would be more preferable than the other?

Thanks

Hi Fairhope,

The video aspect of Type 1 and Type 2 DV AVI is no different. The difference is in the way the audio is stored.

I'd recommend capturing to either type and seeing if this suits your purpose. If not, either re-capture to the other type or use the DV Type 1 to DV Type 2 Converter tool.

Try a short test clip to save wasting time...

For technical info, see here.

Thanks for the quick reply.

I'll do as you say and try small clips with both.

No problem - Post back how you get on.

It's quite a common question, but rarely do people report their findings / preferences after experimentation... It'll be useful for others to know.

Good luck.

Type 1 DV avi has audio and video in one stream. Type 2 DV avi has a separate audio stream. Some people use type 2 because certain programs will only accept type 2 DV avi. My preferences is to use type 1 as I find that audio sync problem are less likely with type 1 DV avi. You shouldn't have any dropped frames when capturing (or transferring) DV to your computer.

Daamon:

I chose Type 1 and captured/transferred the entire video. I chose Type 1 after reading your technical info link and for the same reason as suggested by yg1968 - less likey to get audio out of sync.

I did have a few dropped frames, but believe it was due to the quality of the VHS tape I was using. However, there was no audio out of sync problems.

TMPGenc recognized the Type 1 avi and encoded it fine.

So, I'm sorry to say, I never got around to experimenting with Type 2.

Thanks Daamon and yg1968 for your help.

I had the same question and wound up using type 1 often also. However I've been trying to use VDub in my process and it seems to not like type 1 (I think it ignores the Audio from type 1). So, if I capture in type 1 can I only use VDub if I convert it to type 2? If so, then I figure I should either transfer in type 2 for VDub use or Capture type 1 if I'm not going to use VDub, right?

I seem to be suggesting this solution in every one of my post... But, anyways, Vdub experimental 1.6.2 accepts type 1 DV avi files.
