Frames drop 20 at time.

[ShawnT]

Hello all,

Maybe this has been asked before but I can't find the answer.

I am using Virtual VCR to record programs from my tuner card.

I am running a celron 500mhz. 512 ram, and a 3d sound card. I know not top noch, but that what I have for now.

Well here is the problem.

I am recording shows from my tuner card ati all in wonder.
And I see that 20 frams drops at a time. The sound is fine on play back, but as the movie runs longer the sound falls behind.

And the video gets a bit choppy. Mybe my cpu for the video. Not realy woried about that part. I would like to get the frame rates up and sound to stay in sink.

Any help would be nice.

Oh and I know this is another topic but just wanted to thank Enchanter for pointing me to Virtualdub and DivX.

need to know what speed your hard drive runs at and what compression and video specs you are recording at.

[ShawnT]

I am using an western digital 10 gig drive on winXP Pro.

At this point I am not compressing the sound or video.

320 x 240

RGB24

Fram rate 30.00

Just testing to see what I can get and how.

Any sugestions dodge?



Thanks.

I`d recommend using some sort of compression also if your hard drive is fragmented that could cause frames to drop.

[ShawnT]

What compression would you recomend? I am still new to all this. Just been playing around with avi and divx for about a mounth.

Thanks

Using ANY video compression "on the fly" will only cause your already overtaxed system to drop still more frames. Try using a lossless codec, such as HuffyUV...

[ShawnT]

Thanks I will try out Huffyuv. I will let you know the results.

Well I have tried the Huffyuv codec, It does compress on the fly, but I still have the problem with the sound.

Weather I use compression or not the sound is still off. Sound is faster than video.

I have used resample sound on virtual vcr, but that does not help.

Any thoughts?

Thanks,

ShawnT

A) If the difference between audio and video is constant throughout the video:

Load the file into VirtualDub or NanDub.
Set BOTH "Video" and "Audio" to "Direct Stream Copy".
From the "Audio" dropdown menu, select "Interleaving"
Under "Audio skew correction", set an appropriate number of milleseconds (positive or negative) in the box labelled "Delay audio track by"
Save with a new filename

B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select framerate - and select "Change so video and audio durations match"

Let us know of your success ;>}
