Note: this post is the contents of a discarded youtube video I had originnaly posted . I reposted it here because it contains some useful setup info.
This is a test of a simple recording setup. Overall, I'm dissatisfied with the resulting quality. Key problems are frame drops, blurriness, and the video being shifted too much to the right.
The computer is a desktop of reasonable specs. The OS is Trisquel 5 (like Ubuntu 11). The capture hardware is “EasyCap D60” without the plus, reported in lsusb as 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device. From what I read the D60-plus is completely different and far superior then what I have.
I split the RCA video to EasyCap and a TVscreen via a simple RCA adapter. I also plug the audio into the computer's line-in jack via a simple RCA adapter. I record the video in MEncoder and the audio in audacity. To get the video to work I type this command into a terminal window: mplayer tv:// -tv driver=v4l2:norm=NTSC_M:device=/dev/video0:input=0:buffersize=16:noaudio -hardframedrop -vo xv. Then a green frozen screen pops up, and I force exit it by pressing Ctrl+C in the terminal. The second time I execute the command It works. After I do the above warm-up, I press the record button in audacity and type this in the terminal window: mencoder tv:// -tv driver=v4l2:norm=NTSC_M:device=/dev/video0:input=0:buffersize=16:noaudio -ovc copy -o easy.avi.
I let both things run until I'm finished. The raw files was 12.6GB for this video. In audacity I correct the audio DC offset by a 20hz highpass filter. I sync it by manually comparing the time codes to the first ship being destroyed, and deleting the appropriate amount of audio. Finaly I encode the video for youtube: ffmpeg -i video.avi -i audio.wav result.webm
