Timeline Cursor Hangs

[SaullyG]

Hi,

I have v. 454 installed on my system, everything seems to be performing
smoothly except for the fact my timeline cursor hangs for 3-4 seconds
when playing back any clips on my timeline. Anyone else experience
this?

Thanx,

Saully G.

EDIUS may be prefilling the buffer. How big is your buffer?

[SaullyG]

Hi Brandon,

The buffer is on the default setting, can't recall what that is offhand.

There another option for "quick response" somewhere in there that determines how much of the buffer is prefilled when playback starts.

Quick test though - stick a color bar on an empty timeline - does it still hesitate?

[SaullyG]

Hi Brandon,

I tried your suggestion of placing a 7 second color bar clip on an empty
timeline. Did not really see any noticeable hesitation during playback as
the buffer was running down from 172 to 0.

A while ago I had similar problems with my Logitech USB mouse.
As I never use anything more than the scroll wheel & the right click, which can both be adjusted in windows control panel, I did not install the latest mouse drivers as windows did recognize the mouse correctly.

After installing latest driver, a couple of years younger than the windows logitech drivers, all is good.

So if you are using a USB mouse try it ....

Edit: I had this issue in 4.52

Okay, sounds like one of the following:

1. A bus burst/clog at the start of playback caused by something like SoundFreak mentioned
2. A delay for processing the frames to fill the buffer (this is normal) - a "heavier" timeline will cause a longer delay

If it's #2, then inserting a color bars section or even a section of black at the beginning of the timeline, should result in playback starting quicker (though you'll see bars/black at first).

Even on my old Xeon with E-ide drives it starts playing straight away, even when the buffer is slowly filling.

Still, it looks like driver related, we all know that vga drivers are very inportant, now we just have to add mouse drivers to that list .........

Sometimes I have this problem but not at the start of a clip. It will play for 10-15 seconds then hang for 3-4 and then continue. Is this what your refering to Saully? or is it hanging at the start of the clip?

I have exactly this behaviour on my Storm 2 system with 4.54, and I found switching to OHCI fixed it, so something with the Storm card/drivers is bugging my system. This has only shown up from 4.24 onwards I think.

The NX system with 4.54 is instant playback.

Very cold in London right now - I wanna go home.

Hi all,
The timeline cursor seems to hang up anywhere on the timeline when
resuming play, regardless if a clip has any filters or not.
I regards to the mouse drivers being an issue I don't see where
that has to do with this bug/problem. Then again I am not using
a USB type mouse. I should also note I am using a Sony Vaio
Laptop, ohci, Pentium 4 3.2 Ghz.

@ SaullyG is your OHCI device maybe using a VIA or NEC chip set ? not sure what Sony uses.
both those chip set's create problems for Pro Audio & Video and should be avoided.

@ PaulTV My sytem at work uses DV strom2 card & edius 4.54, making use of only the supplied drivers from the 4.54 update (nothing extra installed or changed) and runs flawless.

My hobby rig at home uses the NX card with edius 4.54, and in the 4.52 version it had issues with the usb mouse drivers.
I updated them (solved the problem) after a while updated to 4.54, so not sure if it was just 4.52 alone, or also in 4.54.
