1452875	2018-08-19 09:13:00	Hi team I'm in the early stages of planning a new PC and am keenly looking at the prospective specs and features required to accomplish the most demanding tasks. It will be used as a home based PC for web browsing, local security CCTV etc The most demanding task would be Motorsport video. What are the things to consider when designing a system for smooth video playback? My current PC is showing its' age with somewhat perceptible jerky movement of race vehicles across the screen, like it hasn't sufficient FPS or is it a PC resources or resolution problem? What's readily achievable for best definition and all round finest user experience? I'd quite like to assemble the machine as I have done in the past. My current machine is M4A78Pro, 6gig ram, on board graphics, 24" LG monitor. What other details have I left out? Please comment. Thanks.	Tbird650 (6754)

Is it streaming vid, playing saved vids (editing vids ?) . What res are the vids ? Almost anything should be powerfull enough to play 'normal" vids . If its streaming , the issues/bottlenecks will be internet not the PC .	1101 (13337)
1452877	2018-08-19 22:45:00	Thanks. Streaming is so often an exercise in frustration because the feed isn't fast enough over my VDSL. I was upgraded recently with faster speed but still video so often doesn't play well. Better user experience by far is to play from my HDD. I'm given files. Typically they are MKV or MP4. I think I've worked out 720p plays better than 1080p but this might be my system limitation. With my proposed system upgrade I want to be able to play anything that turns up without jittering. Studying some of the video files I have now, they range between 25 and 50FPS. Resolutions 1280 x 720 or 1920 x 1080 seem typical. I think motorsport or perhaps most any sport where rapid movement is common, the jitter makes images blurry or frames become jumpy. I recall talk of certain video formats were favoured for sports because of this. I would think gamers would know what I mean so I probably need a gaming quality video card? BTW, my motherboard is something like 8+ years old and in addition there's no proper drivers for Windows 10. It needs updating. I want to study the possible upgrade options long before I'm forced to. If it tips over I don't want to throw money at it. Rather I start the upgrade process now. Thanks.	Tbird650 (6754)
1452878	2018-08-19 23:12:00	My system is just as old & I dont have issues that that. I did upgrade the vid card though . I can even stream vid on my very dodgy ADSL (5Mbs download speed, its really bad) . Any stuttering I get streaming is 100% internet caused (either internet lag or issue at the other end :ie the company streaming ) Chances are the issue is where/what you are streaming from , and the quality of the pre-recorded files you are playing . Garbage in garbage out sort of thing. Download a high quality 1080 test vid (a high quality test vid) & try that Almost any decent PC should be enough for that sort of thing I'd imagine	1101 (13337)
1452879	2018-08-20 00:28:00	To be thorough I rechecked by downloading a 1080p trailer. It played well as I expected it would. It's a far cry from a demanding motorsport race though. Example. Frame capture from a high speed motorcycle race. It can be seen that as the bikes approach they are in focus but as they tip across the frame from left to right, they become exceedingly blurry. Often the jittery-ness can be quite obvious to the viewer. If however the camera follows the bike, it will stay clear. As always these rapid movements create the problem. In motorsport races they are typically from right to left or left to right. 9010 This aspect in particular is what I'd like to improve or minimise. It may be that I need extremely high def video to begin with and extremely high spec equipment to play it. What I need to understand is what gives the best user experience to begin with. Is it high FPS. Is it resolution plus the power to drive it? Are certain video formats better suited? etc. Thanks!	Tbird650 (6754)
1452880	2018-08-20 01:56:00	Looks more like a focus limitation with the camera lens or high speed blur due to shutter speed. No amount of upgrading at your end will make a difference to those. I recommend taking the video file to a friend who has a gaming GPU in their system and try playing it on that to see if upgrading will make any difference.	KarameaDave (15222)
1452881	2018-08-20 02:15:00	Looks more like a focus limitation with the camera lens or high speed blur due to shutter speed. yep, garbage in, garbage out. :) then add in vid compression issues/artifacts, issues from frame rate of recording. Then if streamed, add even more compression & lowered quality. If the file is downloaded, add more compression to keep it within a reasonable size limit : Some free download sites will auto compress (lossy) vid files even more , noticably reducing quality. No matter what you upgrade, you cant improve on limitations of the actual recording or limitations of streamed media. Ask the drivers to slow down, to match the speed of the cameras in use.	1101 (13337)
1452882	2018-08-20 03:02:00	Thanks guys. I tend to think I'd need to get better quality video AND upgrade the system. It's just that I don't know enough about it. Am I asking the impossible? Could the best video in the world look like the sample?? In ten years time we'll be looking back and saying look what we used to have to put up with... and we thought it was normal.!! Good thought on taking video to a gamer. I could take a variety of formats to trial. Nephew is a gamer. Typical size for a race might be a gig, some more some less. Once I got a 10gig race but I couldn't see any benefit to quality. I wondered where the point was. The extra gigs did seemingly nothing.	Tbird650 (6754)
1452883	2018-08-20 03:54:00	tomshardware.com Search for both the GPU and CPU hierarchy. Ranks them in order of performance.	piroska (17583)
1452884	2018-08-20 09:42:00	The main thing with video playback is to have hardware support for decoding any codecs you might encounter. If you manage that you need very little CPU power to ensure smooth playback The best way to ensure that is to have a current model CPU or graphics card. For example 10 bit H265 is starting to become popular and will not play back on older i5s which seem like they should have plenty of power. My experimenting when I encountered one of these files showed me a 7 series intel CPU with the latest driver would play it back easily on a low power i3 (intel NUC) but a 2 or 3 series i5 which is theoretically much more powerful could not (desktop CPUs vs 10W mobile i3) If the integrated graphics won't do the job a current model GPU will often do the trick, something like a 1030 will play almost anything.	dugimodo (138)
