Export Time -- vs. advertised speeds

Craigster wrote on 9/6/2021, 11:56 PM

So, I'm wondering if anyone is getting anything close to the advertised export speeds of Infusion Engine 3 in VPX 13?

Here is from Magix' current ad copy:

"INFUSION Engine 3 now also offers GPU-accelerated export for modern graphics cards from Intel, AMD and NVIDIA.
*12-second export time for 1-minute Full HD, MP4, AVC with Intel i7 6700 and NVIDIA GeForce GTX 1070"

So, I'm using an AMD RX580 in my primary machine, and an AMD RX560 in my secondary machine. Meanwhile, my PCs exceed the baseline (6700) as they are i9 9900k and i7 9700k.

My export speeds don't seem to be any faster than the prior version (and perhaps slower). I used to range from .8 to 1.25 export speeds. (i.e. 48 seconds to 75 second per minute of video -- exported with the same formats as advertised: Full HD, MP4, AVC.) Getting similar on my 9900k/580 system, but 1.4-1.5x on my 9700k/560 system -- which is slower than before. At least on initial tests.

So, just wondering if anyone is getting 4x faster export speeds than previous, due to Infusion Engine 3? Or even noticeably faster exports?

Hi.

I don't think you are imagining anything. you may have noticed the little Intel icon on that page indicating the latest Intel graphic processing generation is supported. and that the GTX is a 6GB nvidia card fully supporting Direct X 12.

I too am running an i9-9900K and an nvidia 1650 super 4GB card and I am not getting anywhere near those speeds although playback is a tad smoother. I also think the export times are longer than before as the HD 630 graphics does little to help during exporting.

Ah, so perhaps supporting Direct X 12 is required?

I have just checked: i9 9900k and i7 9700k both support DX12.

Also, both Radeon RX580 and RX560 support DX12. (And my RX580 card has 8GB).

So, maybe I need to confirm if my PCs are running DX12 or not.

Or maybe try different export options. I wish that Magix would offer actually helpful tutorials, instead of just announcing features!

. . . . I'm wondering if anyone is getting anything close to the advertised export speeds of Infusion Engine 3 in VPX 13? . . . . *12-second export time for 1-minute Full HD, MP4, AVC with Intel i7 6700 and NVIDIA GeForce GTX 1070 . . . .

I can exactly as advertised - 12 secs dead on, however there are conditions ie

using the MP4 h.264 1920 x 1080 H.264 25fps export preset:
source videos AVCHD (AVC) Full HD 1920 x 1080 25 fps
cuts or crossfades with fade in /out for first and last clip (6 clips on the timeline).
the 3 Program settings, Device options settings all set to my RTX 2060

The same project exporting as AVCHD 1920 x 1080 under the same conditions takes about 30 secs, for any RTX or UHD 630 combination in Device Options.

NOTE:

Smart copy was turned off in all tests
As soon as you apply any effects, pans, collages, etc, the export speed drops

Thanks John!

So, my specs divert only in fps (29.97), for both source and export.

I will check/change my Settings/Options to the Radeon cards and re-run tests.

(Previously, I got better results with exports assigned to Intel.)

Hi.

I'm finding my 'real world' projects are on average 20% slower on export at 4K 50fps.

John, I used my 'Tech Tips' project for that comparison.

On the other hand, playback is smoother and there is very little difference in export times between exporting as MP4 or HEVC.

I wish I could find it again but I swear somewhere, whether on line or in the manual I came across the line. 'The program is tuned to make the best of nvidia graphics cards although some improvements should be see using other hardware'.

Cool. I just got a 12-second export on a 40-second video on my slower machine (i7 9700k with RX560 graphics). All 3 Device options set to the graphics card, and the rendering confirmed to use the Graphics card for HW encoding.

Definitely my record ratio!

Thank you, John.
