PC Graphics Card Upgrade Help Please

[muusicman]

Then use a program like AviDemux to trim a short piece of one of your long recordings. Set Video and Audio output to COPY. Set the Output Format the same as your source (MP4, TS, ?). Use the A/B markers to select a region, then File -> Save. Upload the resulting file to this site. Or some other file transfer site. Not to a video sharing site like youtube.

Oh, and upload a short video that doesn't have the problem. So we have something to compare it too.

If I upgrade my graphics card… what are the odds my recording quality will improve? Will the jittery video effect that just started end?

Probably not.

Will the jittery video effect that just started end?

Probably not.

Probably not.

Why is that?

Your graphics card has nothing to do with capturing the video.

Oh. Ok interesting. What else might it be? I’m assuming it could be lots of things. How could I go about checking and possibly upgrading whatever needs to be upgraded?

What I find odd is that when I first start recording it does great. The issue is the longer I record. That’s when the issue comes in. Say the first 30 minutes are fine. Once it gets into 45 minutes to an hour in that’s when I start noticing the stuttering. When I recorded via analog it never messed up. Maybe once in a while it might stutter once. The very day I began using all HDMI is when it began doing it as I described before. Like one day with analog it was fine. Next day using HDMI not fine. Makes me think it’s perhaps the HDMI splitter I’m using.

... What else might it be?

That's what we are trying to figure out. You're not helping at all by not uploading the sample clips that were asked for six days ago. That's the first step in figuring out what's going on. You're just wasting our time with all your useless speculation.

Your splitter is probably not the problem.

Video cards and CPUs are not the only things that can overheat. Capture devices can overheat too, especially those that contain hardware encoder chips like the Hauppauge HD-PVR 2 devices do. 1080p is the upper limit of what your capture device can encode. Capturing component video could be less of a stresser because many devices, including DirecTV satellite receivers, can output 1080i over their component video connections but not 1080p.

... but please upload the video that jagabo asked for to eliminate other possibilities.

Yes, that's what I'm suspecting too.

[muusicman]

I’m thinking maybe once I get a new capture device or a new graphics card it’ll work better.

I’ve now run into yet another new issue. I hooked my Blu-Ray Player up to my HDMI Switcher and as I’ve said I have an HDMI Splitter in the loop too. My HDMI Splitter allows me to bypass HDCP. Some games don’t capture if I don’t have one. Anyway, I tried to hook my Blu Ray into the Switcher now too but for some reason it won’t show on my capture software. Everything else works. 🤷🏻*♂️

You probably will need a new capture card if you insist on capturing 1080p video. A new graphics card can't do anything to improve the HD-PVR 2's captures.

[muusicman]

But I’m not sure if the stuttering issue is due to the capture card or the graphics card.

There is an easy enough way to tell: open your captures in a player that allows you to STEP through the video, frame by frame. If it was captured properly, what you will see should be a smooth progression of still frames - because the display card is not needing to display at the stated framerate, but just show still frames at your set refreshrate. If it shows discontinuity or jerks or shifts in the frames, the capture card & your system is clearly at fault.

You can also test your display card, by just downloading known good reference clips from various sources (possibly including here, as I believe some have provided in the past). Make sure it matches the stated rez, framerate, and codec & bitrates (throughput) that your system is supposed to support (hopefully also matching your display's refresh rate) . If it plays smoothly, your display card is fine. Most decent, recent ones are, because compressed video playback usually doesn't tax your system all that much - it is the extended screens, screen sizes & framerates, and the 3d/gaming rendering capability that shows your display cards' strengths and weaknesses.

The combination of your graphics card plus your CPU is more than good enough for playing even 1080p60 H.264 video smoothly, unless there are defects in the video itself.

[muusicman]

I must apologize. I don’t understand what you’re saying.

I can help you with the first part of Scott's post. MPC-BE is one of several free software video players that has a control button that permits users to step forward frame-by-frame through their video. (MPC-BE has no equivalent control to step backward frame-by-frame.)

Download and install MPC-BE. Open a video then pause the video. Move the cursor to the row of buttons at the bottom of the window. Click on the fifth button from the left to advance one frame. (See picture)
