Last week went from a ROG strix Laptop with an i7, and 3060 Nvidia… to a new desktop build: AMD Ryzen 5 7600x (2GHz more than the laptop), with an MSI 12GB 3060 Shotcut should be running faster now, and my tower has tons of fans in it, and it saves far faster now even with the project being bigger than before
On the old laptop I could preview the source video really easy, specifically when scrolling or clicking on different parts of the source I never saw any lag, and it (the white triangle) would snap to where the cursor (white line) is… immediately, even if I do it a lot in a short amount of time.
On this PC, the playback lags like f’n crazy, and when I click somewhere different on the timeline (source) its abysmally slow to respond, like 10 seconds, sometimes even more, and the more that I do it, the longer that it takes. The playback is fine on the project timeline (bottom bar)
Trying to troubleshoot, someone recommended trying in shotcut settings to:
Change the preview scaling to a lower res, but that didn’t change anything
In proxy, try adding the hardware encoding for the GPU to make use of that, but that didn’t work… maybe I need to restart shotcut but that doesn’t seem likely because it notifies me of changes without a restart, but I will try that in a minute
Lastly try to turn off real-time in settings, but that’s not going to work for me it to be at normal speed, and it’s not changing the responsiveness when I
Even when I was using an ASUS VIVObook i5 with only dedicated graphics, when I clicked on different parts of the source timeline it would go there right away, and there was no lag whatsoever during playback.
Did anyone have some advice on how come that was happening with a superior build in every respect, or how to find a workaround in settings/anywhere else. It wouldn’t make sense that the issue is hardware and I’m running twice the ram (32gb 6000/speed high end ram) as I was before, with a GPU that is a full size desktop version, and 4GB more than the laptop had… was that a bug, or wth?!? I need the PC for work and I’m not buying a new one for several years now.
OK so, a big question, seriously very big, a lot of people do this mistake, where did you plug the monitor hdmi on the tower? The hdmi slot of the gpu in or the motherboard slot for the hdmi?
Idk of shotcut really depends on that but still.
Since it’s a new pc, does everything else work fine or is it just shotcut?
And installing gpu drivers too?
Did you wait for the videos you added to the playlist or timeline to finish making waveforms? On your old PC your videos may already have done that and cached. On your new PC the cache is empty. So while you are trying to test things, it is busy in the background.
Also, how did you transfer your data between systems? I hope you did not transfer to an external hard drive mounted by USB on the new system.
Lol it’s in the gpu slot bro but good thinking
It was actually the first thing that you said about the filles taking time to allocate, it’s working at a normal speed now regardless of what you said about the HDD transfers
Glad to hear the issue is resolved! For others facing similar playback lags in Shotcut, enabling proxy mode, lowering preview resolution, and keeping GPU drivers updated can help. Clearing cache and letting files allocate fully also improves responsiveness.
