How to digitise old NTSC home videos for highest quality (with PAL player)?

As far as deinterlacing: With a good deinterlacer (QTGMC, or at least ffmpeg's yadif=3,mcdeint=2), you can get smooth video at 60000/1001 (NTSC) fps. If your source has quick motions that you'd like ...

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

The cable in the picture is an analogue cable, so it's getting an analogue signal from your camera. It's just a cable, so the signal at one end is exactly(ish) the same as the other. To digitise it ...

Converting from 3/4" video to digital.

Assuming DVD quality would be enough, you may consider archiving 720p mpeg-4 files with a bitrate of 2 Mbits, which would equate roughly to 1 hour = 1 GB data. That would mean 27,000 hours = 27,000 ...

What causes audio sync drift when digitizing VHS?

Why would MP4 compression show up as noise because of a low bitrate when digitizing a Super 8 film reel to digital?

I don't own this scanner, but looking at the specs, it appears to record in MJPEG mode, scanning one frame at a time. The MJPEG codec records each frame of video as a JPEG image. So each frame is ...

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

Calling super-8 720p is confusing. There are no rows of pixels, only grains of emulsion, scattered in a random pattern on the base. That said, film does have an upper bound on its resolving power, in ...

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

You are correct. The pixel aspect ratio is wrong. DV has a fixed horizontal resolution, but can display 16:9 frames by stretching out the pixels. The display resolution is set in metadata, so it is ...
