RT buffers strange behavior in EDIUS 5

[GrassValley_BH]

It's fine for audio apps, the problem is EDIUS is showing you both audio and video, which means it needs to use the render-ahead buffer (can't play what has not yet been computed).

If you lower the load on EDIUS (mute video, perhaps) then it should be fine.

Comes down to a choice when there's too much to continuously do in real-time (which is the case when the playback with audio mixer open is not RT) - don't apply all effects, drop video quality/frames, or don't play RT.

If your project is "light" enough to play RT without touching the buffer at all, then playback should be reasonable with the audio mixer open. But for most, this isn't the case as their project's CPU load goes up and down, mostly depending on the video tracks and effects.

Not wanting to open a discussion about this,

anyway: opening and closing the audio mixer is so far as clicking a button... so... no major problem i´d say

While we all would like to have the mixer open it is not possible at this time because of the way EDIUS works.

That is most likely the best explanation, "the way Edius works".

The last time I played with a demo of avid & ppr it's audio tools do not behave like this, also protools or nuendo are capable of realtime monitoring on many channels running high resolution with virtually no side effects, and running an audio mix of 32bit / 96 or even 192Khz does indeed tax your sytem pretty hard.

Not wanting to open a discussion about this, just making a statement here, besides it's well know that Edius is weak when it comes to the audio side, even by the non edius users.

First of all an audio application does not playback video at full quality ful frame rate.
The reason it work this way to allow realtime adjustment of the audio stream by the edius mixer, effects and tactical control.


If you would load more frames in he buffer you would not be allowed to adjust the frames which are loaded in the buffer.
That would mean that we would not get accurate realtime effects adjustment while playing back.

There is realtime monitor with control + G.

i didn´t know that and (of course) works as you said... any partner here could tell me the reason???

Sorry no reason, but it has always been like this.

Maybe it would be useful for the Canopus engineers to dissect any freeware audio application, they all can do realtime audio level metering without introducing these absurd playback overheads.

Heh guys,

Cool it :-). He is in Spain, and you are in Australia - he might be in Zzzz land for all you know.

ok...

1- i´m in america... that´s the oooooooooooother side of the globe... i´m in your zzzz zone (and NTSC "N-ever T-wice S-ame C-olor" zone) so maybe i´m late to de number 2...


2-WOW audio mixer open!!!!??? that´s absolutely new to me!!! i didn´t know that and (of course) works as you said... any partner here could tell me the reason???


3-thanks...

YESSSSS .... Audio mixer was OPEN ... Closed an solved.
Thank you to all.

If you need master levels you can turn on the on-screen metering feature.

3rd time for emphasis!

Your audio mixer is open close it!

[antonsvideo]

sounds like you have the audio mixer open, close it

[SRsupport]

Your audio mixer is open close it!

I have a system with EDIUS 5, HD STORM, ASUS P5Q-E motherboard and 3 Gb RAM DDR 3 1333.
For a strange reason, when playing timeline, RT buffers NEVER exceed 18 ( it shows a maximum of 18/512 ) It does not matter project settings nor type of videoclip used. Even whit a SD project and and only a matte clip in time line, RT buffer shows 18/512 or less. RT buffers number grow until 18, then freezes, and if any effect or videofilter is applied, then the number decrease and frames are dropped if count arrives to 1.
This is true if playing the clip from timeline. If playing directly in PLAYER windows, RT buffers show 100 or 200 without problem.
I have tried to remove HD STORM CARD and the problem remains ...
¿ Any suggestion ?
