Stream Recording with VLC - Black frames problem

[Kittciokas]

I record videos with VLC quite often from my ISP's IPTV streams. But i have problem - black frames, which takes too much screen:

How can i record a stream without black frames? Or at least crop them after recording without reencoding?

Are you sure it contains black borders? And it's not just a setting in vlc to keep original size or something.
Try play with mpchc and see how it looks like or open in an editor like avidemux.

Where i can check in VLC settings if it's set to keep original size? Well, i upload those videos to YouTube and those black frames remains:

So when YouTube processes that video, it processes those black frames too, so it makes the quality of the video worse.

Can you explain how to use avidemux to cut those frames off? I tried Tools > Scan for Black Frames, it makes a little file on Desktop without extension and i don't know what to do afterwards.

Use the crop filter in avidemux, under video change to a video codec like mpeg4 avc, click filters, add the crop filter, adjust settings. Change format to mp4. Last save as a new video mp4.

I don't want to encode/transcode/convert (don't know which term to use) video, it impacts quality quite noticeably. And it needs too much time, and it's very important to me to make video ready as soon as possible. Is there any other way without encoding/transcoding/converting? I want it to be original quality, preferably .ts video, as the source is.

Try something like Stream Transport which might be able to capture the video stream as-is.

I record stream through UDP protocol, not through website, so it doesn't work for me.
