How to Capture Frame Data …With a capture card –
This isn’t an extremely comprehensive guide on how to capture frame data…But it should do
Step 1 –
Get a capture card that can capture 29.7 interlaced www.zachd.com/mvc2/encode has my other guide for capturing video…Anyways, you’re going to need a capture card that can capture full frames (from DC). So that way when you deinterlace the video it will be 59.94fp/s… So once you have that kind of capture card you have to set the right settings which are usually something along the lines of 720X480 video @ 29.7FPS (with the appropriate field order, hehe). So, just capture something like Cable doing a CR.LP.
Step 2 –
Deinterlace your video with TMPGENC or something that can deinterlace both fields at the same time. TMPGENC is the only one I know (I’m sure there are more out there though). Anyways, with TMPGENC you would go to the Advanced Tab (once you’ve imported your video) and then double-click the “Deinterlace” checkbox to open up the settings window. At the settings window you will see the video and beneath that you will see the options it gives you to deinterlace. Choose the 3rd one from the bottom which is Even-Odd Field (adaptation). Before outputting your video go to the “Video” tab and make sure that it says 59.94FPS. Then export your video wherever
Step 3 –
One you’ve exported your video open it with Windows Media Player or something that can play one frame at a time. With WMP you would go to ‘View -> Enhancements -> Play Speed Settings’. So with that you can just view one frame at a time…So there, that’s how you find frame data…To check, just look at Joo’s frame data. Also here is a video of 59.94fps http://www.zachd.com/mvc2/encode/59….-Odd-Field.mpg <~ just count the frames from that video if you want to see how some things are.
Problems that might come up when you’re trying to do this… –
- Problem: Your source is progressive/already deinterlaced
- Solution: Make sure the frame size is 720X480…I don’t know if it works with 640X480 but it really doesn’t matter since you’re not going to capture lengthy video.
- Problem: When you deinterlace your video it plays back VERY STRANGELY (one frame then the previous…)
- Solution: When you deinterlace you have to specify the field order, depending on your capture card it can be lower field first or top field first…TMPGENC can be told which ones to look at first.
Those are the only problems that I know of when trying to find frame data.
I think if you have all the settings right you can capture frame data with the emulated version of the game… Although I’ve never been able to do that so I don’t know how to help anyone with that. =-\
If I recall correctly, the DC runs at 60fps but because of the NTSC or PAL settings we never get to see the complete 60. I’m not 100% sure on that, but I have found the same numbers for the game as Joo has and I trust his numbers (+ they make sense).
