transcode mistake

[sden1]

I'm trying to save online streams to HDD.
"C:\Program Files\VideoLAN\VLC\vlc.exe" https://www.youtube.com/watch?v=VIDEO_ID --sout=#transcode{vcodec=h264,vb=4000,acodec=mp4a,ab=192,scale=1,channels=2,deinterlace}:gather:std{access=file,mux=mp4,dst=D:\temp\vlcStream.mp4} --sout-keep

When I execute this, video turns out to be small, I want video to have source width\height;
Also, after a second of playing, video output stops and shows static picture instead while audio is playing just fine.
When i type mux=ps instead of mux=mp4 problem solves, but image is pixelated with squares, I don't want to increase bitrate.

I think this happens because of initial low stream quality when I open any stream. After 5 seconds will pass window resize and show actual stream quality, but what can I do with this? I tried muxer caching and network caching, but it looks like those do nothing.
