Hi all, I posted a long time ago on this forum when first starting out but was delayed for a while. I've recently been able to return to my capture work so I come to you with a new question. My setup is as follows:
Playback: Sony ccd-trv65 via S-video and red/white stereo cables for audio
Capture card: ATI TV Wonder 600 USB
TBC: AVT-8710
Operating System: Windows 7
Capture Software:
Virtualdub
I'm attempting to capture standard hi-8 tapes that were originally recorded on the device I'm playing the video back with. The sony camcorder is wired into the TBC via s-video, and the the TBC is wired into the capture card with s-video as well (and the stereo audio is being fed directly from the camcorder to the capture card).
In
Virtualdub I configure the following settings:
Capture Pin: Output size is set to 720x480. YUY2 color space/compression, encoding is NTSC
Capture Timing: Resync is turned off as I'm told with TBC this shouldn't be necessary, and drop frames is enabled because I'm told this really only just hides when frames are dropped.
I ensure that the captured video device is correct and the audio is the capture source.
When I press F6 to begin capturing the playback, I notice that the average FPS I get hovers around 17-18fps. And when playing back the captured file, the video is jittery, and the audio quickly desyncs.
However when I change the output size in capture pin settings to 352x480 and run everything the same, the capture is a rock solid 29.97fps with no frame loss, and the video looks great. The problem is, my understanding is I should be able to capture the output at a higher resolution? At least from what I've read online. Additionally, although the 352x480 actually runs in sync, the aspect ratio is totally messed up, with the capture appearing more vertical than anything (obviously).
I guess I'm trying to figure out what the problem is with my capture setup. Is this something I can resolve in virtual dub with some different settings? Is my laptop limited that it can't record the higher resolution output at the standard 29.97 fps? Is it my capture card?
Any ideas would be greatly appreciated. Thank you.
