For VHS, the signal will be kept highest quality if you connect via s-video, so yes, you should use an s-video cable if your VCR has an s-video output. Depending on how good your VCR is, you may get a significant improvement from a better deck. Quality of the read heads on various VCRs can vary a fair bit and while the majority of the difference was in ...

mini DV is already digital format. The bitrate is 25Mbps. So, 1 hour occupies approximately 11 Gigabytes

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 you'll need a device to convert the analogue signal into digital code. There is a big range of these devices, from cheap USB dongles on ebay like this to ...

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 (according to digital test equipment manufacturer Kramer). Multiplied by a 24 fps refresh rate, this results in 74,250,000 pixels / second. Multiplied by 10 bits ...

Don't trust any hard drive to be reliable! Always backup your footage, you can not trust any HDD, doesn't matter how reputable the manufacturer is. There are always monday batches. HDDs WILL fail at some point, so ALWAYS make backups. Bear in mind that you might find a RAID solution nice to use but that's not a real backup, backup drives are disconnected and ...

It is approximately 11GB per hour, though I do tend to round up a bit when I make my calculations. Digital Rebellion has a handy Video Space Calculator on their website (also available as an iOS app). You can select the format, frame rate, and video length.

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 to look smooth, even in slo-mo, then deinterlace 640x480i60 -> 640x480p60. If you really need small files, you can drop every other frame of the deinterlaced ...

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 GB = 27 Terabytes. So you need to consider a 50 TB storage system (including redundancy and overhead) and a tape backup system as well (LTO-6 has an uncompressed ...

The answer to this question will depend on your priorities to some extent — what sort of quality are you looking for in the transfer, how important the content of the tapes are to you / the world, what sort of budget you have, how much time you want to spend on the project — as well as other variables such as what condition are the tapes are in, and whether ...

Personally, I use a 12 TB RAID array composed of 5 3TB drives. If any one of them fails, I don't lose any data, but if 2 or more fail at the same time, I am up a creak. Other plans can consist of RAID 6, which allows for 2 drives to fail, but at the cost of two drives worth of storage capacity rather than one (so 5 3TB drives would only give you 9TB of ...

There are lots of things to consider before committing to an operation of this size, but there is also an imperative to act quickly. Given that it's SP Betacam and Umatic the tapes are probably beginning to reach the end of their playable life. In a decade they may all be paperweights. A good place to start is the U.S. Federal Agencies Digitization ...

Audio drift can have a couple of causes, dropped frames (which a TBC can help with), and unstable clocks, where the audio isn't recorded at quite the precise rate it should be, causing drift, as Michael correctly pointed out. Dropped frames caused by tape dropouts are a problem if the device skips a frame, without skipping the corresponding frame of audio. A ...

No, a TBC won't solve an audio-video sync problem. Most likely the sync problem is coming from a shortcut in the capture device or driver that samples the audio and video with separate and/or unstable clocks. A TBC built into a "prosumer" VTR like the one in your link will give you slightly better video quality. So would using the S-Video out ...

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 possible to make the file play back properly without re-encoding by changing the metadata. The free, open-source tool ffmpeg can do it. This would be the command ...

In reality, I think the other forum was a good place to ask. But people there tend to vote to close the moment they see the word "video" :o) It is a bit complex to answer. And old movie could probably not have a sharp focus because of the lens, or the grain of the film. Probably there are inconsistencies in the filming across all the movie. Even today some ...

Difficult to reply without knowing if you aiming for a full lossless codec or a lossy one can go too. You talk of H264, but this codec can also be used in a lossless way. If it was for me, and storage doesn't matter I would go for a true (pixel per pixel) lossless codec. Here, excluding some other "good but insane storage hungry" lossless codecs your ...

Even with a floppy drive, you may be SOL -- it's likely the drivers won't work in your current OS. You might have to fire up a virtual machine with an older OS. If the video is analog, consider a USB video capture device. Here's a whole page of them, or search for "USB video capture".

For that kind of quantity, you probably want to look in to a robotic solution that can load and transfer tapes unattended in to a cataloged system. Doing a quick search showed SAMMA as one promising option. I don't have any direct experience with this particular kind of problem, but I can't imagine that manual tape loading or buying an entire robotic ...
