![]() 25 years ago they could do either 720p or 1080i, and there were proponents for either system.ĮBU technical director Phil Laven said, “Tests have shown that viewers see little difference between uncompressed 720p and 1080i pictures, but prefer 720p on compressed signals,” pointing out that for the foreseeable future viewers will never see uncompressed pictures at home. Honestly 720 vertical should have never existed and serves no purpose now since TV's and monitors have to resize to 1080 on the fly anyway. Or use a dedicated Windows 7 PC with this card. I guess we need to open more tickets with Corel to get the driver completely fixed again. If you're getting a lot more inserted frames than that you might not have the updated driver working yet and are still suffering from the worst effects of whatever Windows update broke this driver. If you look at a captured video frame by frame you can see the inserted frame. The imperfect part is it works normally *except* you get one inserted/null (duplicated) frame approximately ever 5 seconds. Did anyone ever fix the frame drop glitch? My memory is a little fuzzy but are you talking about dropped frames or inserted/null frames? The updated driver is not perfect but it improves the situation a lot. There seems to be some often frame drops in the preview & captured video. i really dont know what to do.ĮDIT: I know have the Device setup (with the updated driver provided earlier in the thread by "Buurazu"), and working great in terms of picture quality, but not so great on the fps. I know it is not recommended to use a VM to capture, but if I increased the memory to 8 GB and got a lossless codec to work, is it possible this setup would work? If so what lossless codec is likely to work on WinXP? I tried increasing the memory to 8 GB and it didn't help.īut why are they still selling this, if it doesnt even work for windows 10? I tried downloading numerous patches, with no luck. I know it is not recommended to use a VM to capture, but if I increased the memory to 8 GB and got a lossless codec to work, is it possible this setup would work? If so what lossless codec is likely to work on WinXP? In fact it only showed a single option, (Uncompressed RGB/YcBcR IIRC). I tried to install UTvideo 23.0.0 codec and while it seemed like it installed successfully, VirtualDub did not show it. VirtualDub2 would not show video when I selected the DVC100 as source. The VM only has 1 GB of memory currently. ![]() Gotcha.Īnother question for anyone reading, I was able to use a Windows XP VM on VMware Workstation 15 to capture about 30 seconds of good video with VirtualDub (1 not 2) before it started inserting and dropping frames a lot. In any case 720 means nothing to me, I don't have native panels to display it and I don't have videos shot at that resolution. I don't remember but there was some talk about it here, Either the frame rate or the quality of compression that 1080p and up uses a different codec or something that makes the video quality look better vs 720p. He says YouTube will only preserve 60fps if the video is at least 720p so you have to increase the resolution and when he does that he corrects the aspect ratio by not doing a 1:1 increase. Also, ALWAYS RESIZE *AFTER* DEINTERLACING. If you do it yourself, you get better results. This is because some drivers actually only support 720x480 and resize themselves, usually with a lower-quality algorithm. Shouldn't I capture in 640x480?Ī: No, you should capture at 720x480 and then resize to 640x480 after deinterlacing. Q: 720x480 doesn't always look right in players. In the description he says you can resize it after you capture it: "The typical digital representation of NTSC analog video is this slightly strange aspect ratio of 720x480" I've been capturing at 720x480 based on the instructions in this tutorial video: If your capture card can't capture in resolutions like 352x480 or 512x384, use VirtualDub to do it by choosing the option "set custom format" under the "video" menu. At last, if you want to make a VCD compliant video stream (which MUST be 352x240 at 29.967fps), capture at 352x480 at 29.967fps (this way you get both fields), and then resize it to 352x240 using VirtualDub with the "precise bicubic" filter on. ![]() Now, if you don't need such perfection, or your system can't keep that up, use 512x384 at 29.967 and the result will look quite as good as 640x480. However, Some would say that such a high resolution for a VHS source is a waste of time and space, but I suggest: if you like things perfect, try that resolution. You can do that with software like Adobe Premiere or VirtualDub. If you want your capture to look just like the VHS source (unfortunately it can't look any better), capture at 640x480 at 29.967fps, and then DEINTERLACE it.
