  • Buffer Fluctuation

    I have my buffer setting at 1.5 Gb. During editing the buffer randomly changes from x /300 to x /5 causing stuttering. Is there a reason for this?

    Also, is 1.5 Gb a good setting, or should I go higher?

    Not a lot of need to go higher unless you are using 4K.

    Let me try to give a layman's explanation of the buffer. One of the reason that EDIUS has the best realtime in the industry, is it uses the buffer to read ahead and build a cache of frames so that if it gets to an area that drops frames, it can still play it realtime if it gets through that area before the buffer runs out.

    This process is indicated by the 2 buffer numbers. The second number is the total buffer and is dictated by a combination of your project preset, buffer number, and RAM. The closer the first number stays to the second, the easier it is to play realtime. If the first number starts dropping, it will still play realtime until it drops all the way down (this number can be adjusted, but it is generally 1 or 2). At that point you would need to render.

    Also be advised that a few things will not let the buffer fill all the way. For example, having the Audio Mixer open and any track not in Off position.

      From reading the OP's post it seems a little unclear. I got the impression he was saying that the total frames available for the buffer is changing
      During editing the buffer randomly changes from x /300 to x /5 causing stuttering
      Which would seem odd if that were the case

        If he used the Audio Mixer it could go down to 5.

          Adbear - you are correct. My problem is not that the FIRST number is dropping (I understand why that happens) my concern is that the second number is changing from 300 to 5. So unexplainably my max buffer becomes 5 in the middle of editing a project - which doesn't allow much room for buffering!

          So why would this occur?

            Please post a screen shot of your Audio Mixer.

              Did you see my post? I explained why.

                Previous posts did not answer why the buffer "limit" would change from 300 down to 5 while editing.

                  Well as they said, if you have the audio mixer open the buffer drops to 5 frames. Do you have it open?

                    Here it is right here. If you have the Audio Mixer open and not set on OFF your max buffer can be 5. I also mentioned it in the last sentence in post #2 of this thread.

                      That should explain the request for a screen shot of the audio mixer.

                        I had been using the audio equalization function. When I click to close it does it still remain on? I would assume if I closed it it would no longer be active. No?

                          I do see now that the buffer drops to the 5 limit when the equalizer box is opened. I never realized that the audio was affecting the buffer until you pointed it out. Thanks!
