intensity pro Issue

[Joe Beckwith]

Yeah I’ve always used VirtualDub when recording. I’ve tried Media Express and didn’t like it.

I tried doing what you said but no matter what the audio is messed up. Some settings make it lag way ahead of the video and it’s all sped up, and some settings make it lag ahead but it’s slowed down.

I’m hoping it’s just a computer specs problem and that it will be solved by upgrading my computer, but I don’t know.

Valentin gave all good suggestions but if you’re still encountering issues then we’ll try other things.

If you’re still getting dropped frames, then I think that should be addressed first. Because when I was having problems I made sure to fix that first. Once that was fixed everything else fell into place.

So make sure Capture->Hide display on capture is enabled to save PCI bandwidth and unchecking Audio->Enable audio capturing. If you’re still getting dropped frames with this settings then you’re system is having trouble just recording video. So a new system would at least help that.

If not then we can start checking your audio settings since that might be what’s causing the dropped frames.

Here are the results I’m getting when I try those settings. No frames dropped but lots of frames inserted at 60fps.

It looks fine when I play it back… like it doesn’t skip around or anything. When I tried to capture with Media Express I always used to get the message that said “..dropped frames… try another setting”.

Just to add to the above… it seems to start off synced fine, and then becomes unsynced the more I record.

Sorry to continually add to this post, but I haven’t yet discovered an edit button.

I’m doing more testing, and I decided to try a different audio source. I’ve discovered that by using the “Line In” source instead of capturing from HDMI audio, my problem is solved. Only new problem is that I’m using a lousy audio cable and the sound (while now in perfect sync), is obnoxiously loud.

New question: Is there a way to capture audio from the Red & White RCA cables from my xbox by using the component adapter that came with the BMP (while capturing HDMI video)?

[Rodney Relosa]

Sorry couldn’t get back to your feedback. I was waiting to get home to try out my setup to compare with your capture data.

But I’m glad you solved your problem.

I won’t be able to help with your other question because I have a 1st gen 360 with no HDMI output.

This thread is kind of abandoned by now but I noticed that you fixed your problem with getting a black screen sometimes Valentin? I’m wondering how you fixed this because the only solution I have found to fixing it is turning my computer off, reseating my card, then turning my computer back on. This happens every time I turn my computer on without first reseating it.

As for Joe’s question, there is a setting in the black magic control panel for HDMI input and Analog RCA audio. This will allow you to use HDMI for video input as well as the red and white plugs on the component adapter for audio.

Also, your problem with the audio being too loud is because you probably have your input volume on your line-in set too high. I found that when I am using my line-in to record game footage I have to set it to record at about 1/2 to 3/4 volume.

As for your other problem with the out of sync audio; I recently encountered that problem when recording with Blackmagic Media Express, but was able to recover my footage with VirtualDub. The reason that happens is because your game is outputting 30fps but you’re trying to record 60fps. When this happens your computer records the 30fps but your video gets tagged as being 60 fps. When the video is played back, it will play at double the speed because it is trying to play 60 frames of the footage every second when you recorded only 30 frames every second, but the audio will be the right speed. When you playback the video at 30fps, you get what you showed in your video links: the video is slowed down to 30 fps (half speed), but the audio is also slowed down equally as much, making it out of sync and lower in tone.

I hope this helps you further optimize your setup.

Hey Sean,
I’m still following new posts on the thread.
I must admit i didn’t fix the black screen issue, and i have to do exactly the same than you each time i start mon computer.
My point is the card is a little too short to get to the PCIE port, my ATX case might be the problem, but frankly, i don’t feel like changing it just for a capture card.
Anyway, i’m getting used to it since i don’t use the card too often, but still, to have it start nicely without having to unplug it each time would be better.
nice work for explaining the 60/30fps issue, that makes so much sense, i can tell some friends with the same card how to fix the problem now, many thanks.
Valentin.

The only solution I have found to fix the black screen problem is exactly what you said: to shut off computer and reset the card.

Sometimes I get a black screen at first but switching between “playback” and “capture” a few times usually solves it. If that doesn’t work then yes, I have to reset the card.

And thank you for the explanation to the 30/60 fps issue.
