region with YUV curve - buffer/processor limitation

[Jeff Chandler]

No problem here (with SD footage), even with soft on and doing a chromakey at the same time. Buffer fills and stays filled.

Mine too soft edge on.

[Rusty]

Soft edge causes my E6300 system to slowly empty the buffer. Adding any degree of transparency guarantees timeline death.

Buffer is at its' smallest possible.

[Aristotelis]

My test was with soft age on and I had no problems at all...

Bit of a breakthrough in nailing the problem. (but not solving it)

The problem only occurs with "soft-edge" set to on.

So it needs to be region+YUV+soft-edge then buffer reduces quickly.

However I need soft-edge turned on for a gradual drop to darkness around the region edge.

anton - I know about the realtime audio mixer/buffer thingy, and it's not open.

I'm just talking about a specific incident with this one filter, everything else is 100% spot on.

BH - will try reducing buffer.

I'm going to try and get a video up of it today.

[antonsvideo]

I wonder if he has the audio mixer open? that would do it

[GrassValley_BH]

Try reducing your buffer to the minimum and see if that makes a difference.

On my system the buffer climbs and does not drain in a dvcprohd project

[rone]

Well thanks once again for trying. My buffer is maxed out.

Just to re-iterate Region/YUV does work, it just drains my buffer quickly and no other filter does this - which is why its so annoying.

[GrassValley_BH]

The same effect plays OK here with my lowly P4 too.

There must be something else going on - maybe a clip on a network drive or something?

[SRsupport]

2 different people have tried it for you and it plays back on our systems. I guess there is some little detail you are missing.
The audio mixer and/or waveform monitor/ vectorscope are closed right? The buffer is set to 512 mb?

[rone]

Thanks for trying it.

But I've two systems with seperate Edius installations, I've had this glitch with different versions of edius, and fresh installations on both.

[SRsupport]

This is strange I just tried it in the following projects and it works on my notebook
1920X1080 with true 1920 footage played (buffer dropped to 20 -stationary-but it kept playing)
1440x1080 with true 1440 footage played (buffer climbed when playing)
1280x1080 with 1440 footage (buffer climbed when playing)

I have 2 gig of ram and my buffer is set to 512 mb

btw I had my anti virus program its real time monitoring running to put more strain on the system.

I think there is something wrong at your end

[rone]

In either case (HD/SD) I have buffer on max - can't remember what it is... don't have edius in front of me.

But I've tried playing from pre-buffer (shift+space) and from just play. It doesn't make any difference the buffer empties within a short amount of time.

No other effect or filter places this load on the buffer.

If you perform the YUV curve without region - no problem.
