Topic: For a 1280x720 video, issues with getting smooth video

Hi, I have a 1280 x720 (16:9) video that on my desktop computer: AMD Athlon 64 x2 5000+, 4gb ram, GTX 680, the video is not being played smoothly and the audio is ahead of video. Keep getting high cpu usage message too. The profile that is auto selected is 1920x800@24 and gpu acceleration is on. Why is keep selecting that profile, because on my laptop it uses the 1280x720@24 one? Is the processor not up to the task?

1. Profile 1920x800@24 was selected because of framerate. Look at framerate of your 1280x720 video. I think it is more than 24 fps. If it is above then SVP select not 1280x720@24 profile but next biggest profile. You can change this behavior by unchecking option: SVP tray menu - Profile selection method - Choose one with nearest pixel rate
2. Performance. I think SVP made a mistake with selected profile. Try to change it manually: Start menu - SVP - Reset Profiles. Choose: 1 > g
3. How many Real-life FullHD score you get in SVPmark? 400 SVPmarks or more?

Is the processor not up to the task?

Yes. Your processor is close to minimum requirements. It can process 720p at weakest settings.

To compare I have GTX 660 Ti but Core i5-3570K processor (2400 SVPmarks).

I will try 1 and 2 thanks. Here is my score real-life fullhd

So tried 1 and 2. Now it is selecting the 1280 profile but performance is very slow. Also video is 25 frames per second (the actual rate video is encoded that is).

It is HD not FullHD. Select in SVPmark before RUN benchmark: Additional test options - FullHD-video. The Result must be around 400.

60 fps - [SVP] good:            0.88x (53.1 fps)
60 fps - [SVP] high:            0.71x (42.9 fps)
60 fps - [SVP] highest:         0.35x (21.2 fps)

All three tests are slower than Realtime. And it is for 720p (24 fps > 60 fps smooth). Your system can not process it in Realtime.

48 fps - [SVP] fastest:         2.61x (125.2 fps)
48 fps - [SVP] simple 1:        1.66x (79.9 fps)

You can use framedoubling (Double source frame rate (2x).

When run SVP choose it manually in Profile settings window, setting "Target frame rate".

I reset profile of 1 and C. When I used G it had higher cpu usage? Also, I changed to vmr9 renderless for video renderer. This seemed to work Around 72% cpu usage and the svp index stable. Also to note my monitor is 75hz and the framerate is 75 fps.

When I used G it had higher cpu usage?

Yes. Processing in SVP devided into vector search job and frames composing job. C = CPU only. G = CPU search + GPU compose. When you select C you select settings to work both search and compose on CPU with the same abstract performance level. Thus settings are a little easiest than G.

This seemed to work Around 72% cpu usage

Good! Does option GPU-acceleration enabled in SVP tray menu?

the svp index stable. Also to note my monitor is 75hz and the framerate is 75 fps.

That's good! Nice to see. smile
Do you satisfied with the result?

Re: For a 1280x720 video, issues with getting smooth video

Yes the gpu acceleration option is enabled. Yes, I think results are satisfactory thanks for your help smile
