I would say that the lag on V14.5 seems worse than V12.6. There has been reports regarding the lag with the mouse scrubbing on the timeline in the past, which was improved.

I don't think you have to gather evidence regarding the source, it's the developers who know their software and the Shuttle Pro is sold as an Lightworks accessory.

They may or may not be able to address an improvement in V14.5, but an early report makes a solution in that version more likely.

Some lag may be related to decoding of long GOP video formats. I am working with i-frame only professional DI codecs and PCM audio in Lightworks. I find no noticeable difference between keyboard jog and shuttle jog on my laptop. Performance in 14.5 RC9 seems to be the same as it was with V12.5

Some are almost happy with the behaviour others entirely not, that's the stuff useless feature requests are made of.

There are so many people complaining about jog-wheel behaviour over the years that devs should be pretty aware of. My conclusion, no will, no time, or no money are the cause.

By the way Razz, did you get yours for free?

I was using 32 bit V12,6, it seemed to have less lag than V14.5, although a number of factors could enter into this.

No I bought mine from Contour direct before Editshare sponsored their version. Been using it since V11.

I followed your advice and posted in beta forums.

From my understanding of the issues they shouldn't be so hard to optimize with a second set of nudge and jog commands (to preserve the existing), but I doubt that there's enough time to implement with V14.5. Let's see what happens.

I have it on the list, anyway.The list is long and doesn't forget.

In case anyone is concerned about all this, the jog wheel is extremely effective for slowly scrubbing though your video and audio frame by frame.

Why should we thump you, George? If I'm correct, that's "plus ça change, plus c'est la même chose", which could be rendered colloquially as "the more things change, the more they stay the same" or perhaps "whatever the change, it's more of the same" (lit: "the more it changes, the more it’s the same thing").

In any case, why should that in any way contravene forum guidelines?

[EDIT] Interestingly, I thought that I'd better check my literal version on Google translate since my French is very rusty. That came up with "what goes around comes around". I can't for the life of me see how that was arrived at - I don't think that conveys the same sense at all. The French original is far more cynical than that.

I did a thorough check of jog behavior under RC9 on my system last night. On the keyboard jog left is assigned to up arrow and jog right to down.
Three quick key presses moves one frame right. Two quick key presses moves one frame left. This is still consistent with past behavior.
Jogging either way with repeated key presses at about 4 fps, stop is frame accurate. Much faster than that and it might overshoot stop by one frame, but that could be my reaction time too. If I hold the key down it ramps speed up to key repeat rate. When released it ramps down and overshoots by several frames.
With the shuttle jog wheel the movement does not quite match up with the notching of the jog wheel. But the behavior is pretty much the same though not quite as precise as the keyboard. I think this may come down to the quality of the Hall encoder in the shuttle more than a problem with a Lightworks command programmed for their much higher quality console.
Be interesting to hear from Craig or someone else using an X-keys console to see how that compares.
Nudge using the shift + play buttons on the shuttle is exactly like the keyboard. I would expect some slop assigning this to the jog encoder.
That nice sub frame audio crawl initiated with a single notch left of the jog wheel or keyboard jog in past versions is gone. That may have been a bug, but I liked it.
The mouse wheel function in preview windows is nudge. It doesn't scrub audio. With my Logitech mouse it is frame for frame accurate. If we could assign jog to a mouse wheel I expect behavior would be the same as the keyboard behavior.
With keyboard jog as described above, one can precisely adjust one frame at a time with audible audio scrub.
Observing the behavior of the on screen control panel with key jog, the first key press takes it out of pause, the second or next two move one frame and return to pause. I imagine this is a necessary chain of events for the Lightworks console functions.
The test was done on a Cineform 10 bit 4:2:2 i-frame clip.

A quite long double post, David. Takes a while reading it.

@John – The fear was of reprimand for posting in a non-English language. Our friend Hugly seemed a little out of sorts over the length of his list of requested features, and I thought a fractured rendition of the French epigram might raise his spirits. The German reads [or SHOULD read], “The more things stay the same, the more they change.”

I'll keep it with "Stillstand ist Rückschritt" (Konfuzius, I think).

Google translates that to "Stagnation means regression".
