Hey Guys,

We've improved memory handling and multi-threading which has helped speed up exports by around 20%. We'll continue to try and tweak performance as we go along, but this is a good start.

That being said, video encoding and export is extreamly processor intensive so so it's unlikely that we'll see realtime exporting without hardware changes. So our goal is 2-3x realtime which is standard for most video applications.

Hi Guys,

we've just pushed a new update of Silverback (1.0.2) which should solve many of these issues. So it would be great if you could grab a copy of the update and let me know how you get on.

Hi Vladimir,

Glad the new version is working for you. However I wasn't 100% sure what your reference to flash sites was about so could you expand on that for me please.

Introducing the 1.02 Release

I wanted to let everybody know that we've just released a new update for Silverback. This update improves stability and memory handling while increasing export speeds and fixing a few small bugs.

* Improved export speed
* Reduced exported file sizes
* Improved memory handling
* Fixed chapter marker bug
* Fixed intermittent exporting bugs
* Improved multi-threading support

If you plug in a USB camera it should automatically take precedence over from the iSight. While we don't officially support any cameras other than the iSight, Silverback should theoretically work with any cameras the hook into the underlying video architecture, which should be the majority of them.

Sorry to hear about your audio problems Calum. This is a new issue for us so we've raised it on our bug tracking app and will look into it asap.

Andy Budd replied on March 30, 2009 12:57 to the question "Export iSight video only?" in Clearleft:

Hi troyboy27,

You can't "export" only the video portion. However the native video files are easily available. Just go to Library > Application Support, Silverback > Sessions and you can find the native videos inside the appropriate session folders.

Andy Budd replied on March 19, 2009 04:33 to the question "How do I pause the recording if I don't have a remote?" in Clearleft:

You can pause in two ways.

1) Command-Tab into the app in order to bring up the floating bezel control
2) Select pause from the Silverback icon menu in the menu bar

Hi Rui,

Are these freezes happening on a regular/predictable basis or are they more random? It would be extremely helpful if you could send the crash reports over. You can find them Library > Logs > Crash Reporter.

To tell how much resources the app is using, if you could open up the terminal application and type the command "top" while the application is running, you'll be given a complete profile of your machine. If you could save the results and send those as well, that would help. My email address is andy@clearleft.com.

Video capture is actually quite memory intensive so my suspicion is that Silverback is running out of memory. However 1.5GB should be OK (what version of the OS are you using and what processor?) so we may need to tighten up the memory handling some more.

Hi Vladimir,

Really sorry to hear you've been having problems with Silverback. It sounds like you could be having memory problems leading to data corruption so can you let me know how much memory you have installed on your machine?

Could you open up your terminal, type "top" and then send me the results.

Thx

Sorry Rui, it seems the notification for this question got caught in our spam filters. While we do have a few instances of issues during export, this is the first one we've had during capture. Can you let me know how much RAM your machine has, how much RAM Silverback was using before it crashed and what other applications you had open.

Andy Budd replied on March 11, 2009 23:53 to the problem "Stopped program on big tests (more 40 mins) on MacBook Air 1.8, 2Gb" in Clearleft:

Hi Vladimir, could you expand on this problem and let me know exactly what's happening?

Andy Budd replied on March 11, 2009 23:52 to the question "Video is lagging behind the sound?" in Clearleft:

Hi Guys, we've had one or two reports of lagging but it's not something we've been able to replicate. Is there any way you could send us your raw session data to see if we can replicate the issue on our machines?

Andy Budd replied on March 11, 2009 23:50 to the question "Pressing "Cancel" when an export is running should stop the export." in Clearleft:

We've found that cancelling can sometimes hang the system so we're looking into this and hope to have a fix soon.

Andy Budd replied on March 11, 2009 23:48 to the question "Can you export using the demo trial version?" in Clearleft:

Sorry Kit, that is a known bug affecting a small number of users and one we hope to get resolved soon.

Andy Budd replied on March 11, 2009 23:48 to the problem "Buggyness and Crashing" in Clearleft:

Hi Kit,

Unfortunately we do have a memory bug that is affection a small number of users. We're currently doing our best to locate and fix this bug, so hope to have more information soon. In the meantime, if you are experiencing problems exporting a particular session, please keep trying as they will usually export after a couple of attempts.
