Virb Edit 2.6.2 Issue: jerky video

Hello!

I have installed Virb Edit 2.6.2 on 2 PC:

PC1) Lenovo Z580 Windows 8.1 update 1 8GB Ram Core i5 Intel HD Graphics 4000
PC2) Asus Transformer T300LA Windows 8.1 Update 1 4GB Ram Core i7 Intel HD Graphics 4400

On the PC1 Virb Edit works fine with minor issue (sometime crash, but without damage...)
On the PC2 Virb Edit works bad with video jerky on any video preview...

This problem on PC2 there wasn't with previous release of Virb edit (2.5.1) and also with beta 2.6.1, but there were other problems: speed control doesn't work, often crash during edit and very very often crash during exports at randomly percentage of completation.
Other video player (WMP12, VideoLan) work fine without jerky.

The 2 PC have the same O.S. updated to last Microsoft fixes.
I try to reinstall Framework .net 4.5 and I have updated graphic card driver to last available on asus support page.

The PC2 is more recent than PC1 (buyed 1 month ago) and also more powerful (i7 instead i5, SSD Disk instead SATA Disk)

The PC2 was a present for my wife, and she would like to use to make Video for Virb because she is an official Virb Tester ( http://www.provagarminvirb.it/search.html?searchtesteur=26&ok=OK ), but she cannot, and she must use my PC1...

I am an IT engineer and a software developper, so if someone of the Garmin support want to ask me other details or ask me to do some tests, or running some diagnostic tools on this platform, I am available to help him.

I understand that it is very difficult to make a pc software running good on different operating systems, different hardware, different drivers with different versions because I continually encounter this problem in my work.

Thank you

Thank you for giving us such details, and I am very sorry you are running into these troubles.

Was the second PC plugged in to external power? Make sure the power profile is set to at least "balanced" (not power-save).

We are working hard to improve matters.

Thanks Falagar,

Ok, second PC was not plugged into power.
Now I try to plug and set profile to balanced and the behaviour of the Virb Edit is improved, but is still jerky, less, but always jerky.
If I unplug power during playing video (big player) video come back very very jerky like a sequence of still pictures, when I plug again, return "almost" smooth (smooth for about 4 sec and after 1 sec stopped and so on). The smoothness on the small video (during editing) is better.
Without power, sometime, video remain black for several tens of seconds. If I iconize VE and maximize, I can see the first frame of the video but it is hard to start.
With the power profile "best performance", the jerky was reduced more but didn't disappear totally.
Without power, VE is unusable at all, with power plugged in, is usable but video isn't smooth as it should be.
Audio is never jerky and always smooth, but loss synchronization with video like bad dubbing.
With PC1 there isn't this trouble so evident, if I unplug power, I can see the video just imperceptibly less fluid.
PC1 is a notebook at all, instead PC2 can be transfomed into tablet...
I hope that this problem disapear on next release of VE, It don't very clear to me how power profiles could be involved with the fluidity of the video playback, but probably You know.
If you need other things (log files, infos, tests,...) , do not hesitate to contact me on this thread.

Bye

Thanks for your reply.

The power profiles matter because choosing a power-saving mode basically throttles the graphics card which is what does most of the work during playback.

But we are definitely looking into improving this.

(Technical details for the original poster follow)

The difference between your two PCs with regard to performance is that the first system has dual-channel memory rather than single-channel memory for the second system. The main difference between the HD4000 card and HD4400 is a few more processing cores which doesn't help in moving video data around the system.

I don't think that you can upgrade the ASUS to 8GB -- because of the thin profile of the convertible the memory is soldered in -- so you'll have to wait for performance improvements to VirbEdit which will reduce the load on your graphics card.

Perhaps the Garmin Virb box should clarify the specification needed to run the software??

I agree that we should have done this already. But we will publish recommended hardware specs soon.

Thank you for the clarification, HIKERDAVE.

I am confident that Garmin will solve all problems.

For the moment 2.6.2 has intrduce some issues, annoying but non-blocking but it has resolve other issues of 2.5 more blocking (crash on export).
