How to protect frame drops while converting AVI to MKV?

[ConverterCrazy]

I captured streaming video as AVI file using NCH Debut(Trial version).

The video plays a little jerky and video/audio is of poor quality. But the 19m21s AVI file size is huge - 4.9GB!

Converting with various converters have failed. AVIDEMUX converts to MKV but loses many frames in the process. While saving shows 0-1fps!

Converted file is more jerky.

What can be done?

The video is topical and thus important for me.

Any help will be appreciated.

Thanks

The frame drops are in the original capture.

Thanks.

So, I have to recapture the video?

Yes.

Also, record the result to a secondary hard disk, and use UNcompressed video and UNcompressed audio,
LATER you can edit and shrink both.

If that capture software doesn't offer you those options, then you'd better drop it.

Thanks.

Will do.

If the OP's profile is up to date he won't be able to capture uncompressed video. His hard drive isn't fast enough.

Use a fast lossless compression codec like HuffYUV and capture as YUY2 (or some other YUV 4:2:2 format), not RGB.
