See pic below. Using vMix 13 and 14. The MP4 was recorded using version 14.0.0.? (cant recall) but has seemed to always have this problem. Both systems setup to display 1280 x 720 PAL 50p Any ideas or is their something that can be done to fix ? Ash attached the following image(s): vMix_MP4_Diff.png (1,331kb) downloaded 30 time(s).

Only diff I can see between both versions. But I cant see a vMix64.exe.config. EDIT: Ok got it and changed but still the same If I change the Settings to 1920 x 1080 50p it fixes problem but I need 720p. Ash

Perhaps there is an odd graphics card issue here, what graphics card is that system running? Is it the latest drivers? (If so, what version?)

Will post version details later today. But this also occurs on other machines. My old desktop is used to create graphics has the same result and its running an old 460 Why only on v14 and not v13? Will do some more tests. Ash

Maybe there is an odd setting that is different in vMix 14. Could you email me your settings file (export it from Settings -> Export) and I will import it and run the following tests: 1. Create MP4 recording at 1280x720 50p 2. Add the recording back in vMix and play it back.

Tried other captured files and behavior is same for all. i.e. Settings -> Output Size and Master Frame Rate - all ok except 1280 x 720 @ 25p / 50i /50p even tho the mp4 file was captured as 1280 x 720 50p or 25p Is there something weird about my mp4 codec?

Using provided settings export and NVIDIA Graphics Driver 344.75 2. Added new Colour input set to Colour Bars 3. Created MP4 Recording at 1280x720 50p 25mbps for 20 seconds 4. Added recording as input and played it back. Screenshot of results attached. admin attached the following image(s): screenshot.png (52kb) downloaded 1 time(s). You cannot view/download attachments.

Checked out NVIDIA Control Panel -> Program Settings and changed setting to Use Global Setting (see pic) Also set Global Settings tab -> Preferred graphics processor to Auto-select and correct rendering now appears in vMix. So question - what setting to use to ensure that vMix uses the NVIDIA GPU rather than the integrated graphics? Ash attached the following image(s): bars_2.png (68kb) downloaded 2 time(s).

I've done some research and your G750 also has integrated graphics alongside the nvidia graphics while my G750 with the 765M only has nvidia graphics. Unfortunately the use of integrated graphics alongside the nvidia tends to drag down the performance of both. Auto-select is probably the best option for now you can also try downloading the latest intel graphics drivers. Regards, Martin vMix

Have you been able then to replicate the same issue with the 3D settings? Interesting subject. Regards Ash EDIT -- So its not possible to force/coerce vMix to use the NVIDIA engine will the system default to integrated? Can this be controlled?
