HDV Proxy editing

I am trying out VS11 trial and trying to edit footage from a Canon HV20 HDV camcorder. I think I need to use proxy editing because my machine does not appear fast enough otherwise. It is an Athlon XP 3000, which is 2.2 GHz, but is "supposed" to be like a 3 GHz machine. I have 1 GB RAM and am running Vista.

A few questions:

1. How long is reasonable to generate a proxy file for a clip? A 2 minute HDV clip took about an hour to generate. Seems excessive and not that useful.

2. Once the proxy file is generated, do I have to do something to tell VS to use it instead of the original file? Is there a way I can tell if the playback inside of VS is using the proxy file? When I played back a clip to preview it before generating the proxy, performance was very variable. Sometimes it plays very slowly, and sometime a little better, but never that great to make me think that I don't to use proxy mode editing. This variability in playback is making it difficult for me to tell if it is using the proxy.

3. When I capture the HDV clips from my camera, the check box to split scenes is grayed out. Is this normal?

Thanks,

Mike

I would suggest not using the proxy file if you computer is supposed to be as fast as a 3GHZ Intel. Proxy is supposed to be for computer less than 3GHZ.

I turned my proxy editing off and have no problems, my processor is 3GHZ.

HDV editing is slow, don't expect it to be anywhere near as fast as standard video.

Thanks for the reply. It is not just slow, but somewhat unusable, that is why I wanted to try the proxy editing. Anyone have answer to any of the questions?

Thanks in advance.

I've a HV20 and am using VS11+ and got an answer from Ulead on the "Split by Scene" being greyed out - Unforntuanlty is not currently supported - you can run it post catpure and it will do it based on Content NOT time/date stamp (which for me is not ideal) and even then it just using mark in / mark out points. You could try using HDVSplit for capture but it does create a slightly different file format (Transport Stream) than Video Studio (Program Stream) but this may make no difference to you pending your workflow. Also some have reported that HDVSplit leave a "black" frame at the end of each segment but I did not see this personally.
