OLD HAUPPAUGE HD PVR SOFTWARE 1080P
as for my personal stream settings,I have OBS scale from my base res of 1080 down to 720 (I do this in video settings, so i can use a downscale filter, not in output settings) and set my FPS to 30 (personal preference for my steam, less frames = less pixels because the encoder has more time for each frame) and I have no problems as long as i do all of that Top 10 Best pc pvr software Reviews HAUPPAUGE HD PVR Pro 60 HD 4K in/Out 1080P 60fps Capture and Streaming PC Connected and Stand Alone for Zoom Skype YouTube Live and Twitch 1684 179. as for the stuttering, at least in windows 10, there seems to be an issue capping the HD PVR 2 video footage when a game is running in fullscreen windowed mode, so make sure your in exclusive fullscreen, that makes the stutter lessen/go away.
let it use the default settings, and it should default to 1080/highest FPS. Ive been using PVR-250 for years and its quality is enough for old tapes. As usuallyquiet said it must be PAL model for my country. The PAL version would probably be far more useful than the NTSC version for VHS video capture in Turkey. Make sure to NOT use custom resolution in the properties panel for the HDPVR2. The Hauppauge WinTV PVR-250 has distinct PAL and NTSC versions.
