Can I digitalize a video with a RCA-Jack adapter?

Is it possible to capture video signal waveform as audio for video replay?
The short answer to your question is "no". The sample rate of video is typically measured in MHz or GHz. If you have a 1080p24 signal at 8 bits per pixel, the actual frame is 2750 x 1125 pixels (...

Does digitizing Super 8 film at 4K resolution make any sense?

What's wrong with this MP4 file? Is the pixel aspect ratio wrong?
