I have recorded 30+ tapes on a Sony TRV350 Camcorder. They are recorded in Digital8. I am going to transfer them to my computer via firewire (Sony Vaio). I know how to capture the video, but I don't know how to get the best quality version.
I have already tried PMB (default software on Vaio). There were no capture options as far as I could tell, with the default settings resulting in an .AVI file with DVSD type 2 video.
I then tried AVS Video Recorder. I selected the native format which resulted in a .DV file.
I was going to try WINDV as a third option, but I have read mixed reviews about its functionality with Windows 7, 64bit.
My OBJECTIVES are:
A - archive these Home videos for posterity in the best quality
B - store the videos on my computer for viewing with a server like PLEX.
*PMB gave the option of separating the videos on each tape into different files. I would prefer this if it does not sacrifice quality.
My questions are:
1) what is the native format of Digital8? I have read mention of raw or uncompressed DV, but how can I tell if the video is raw or uncompressed?
2) is either of the two options I already tried going to give me the quality I want? If so, which? If not, what should I use?
3) will I need to convert the files to use with PLEX ?
4) Knowing my objectives, what do you recommend to achieve them?

Hi, welcome to the Forums.

The format on your tapes is already digital, and in DV, and there is no need to go from analog back to digital (ex: VHS), and any conversion is both a waste of time and, in most cases, a loss of quality.
Yes DV is compressed, but that doesn't mean you will get inferior quality using it for your scheme. Using a lossless codec would be much bigger in file size, and not give you any better quality, and using something like MPEG-2 would save on space over DV, but would be considerably lossy given that it requires a conversion (and would reveal many artifacts, such as on camera pans).
It's like taking a DvD, that has native MPEG-2 on it, and converting it to lossless. Not much benefit there, even though MPEG-2 is lossy (and even more compressed). Wouldn't a more optimal transfer be a copy of the MPEG-2 instead? (Not condoning piracy, just being hypothetical.) That's what using DV would be with your tapes - a direct copy.
Your Digital8 tapes will only be as good as the DV video already in them, as the DvD would only be as good as the MPEG-2 on it.
Use DV.

WinDV does just that - takes a direct copy of the DV, and audio, on your tapes and wraps it into an AVI container. No quality lost. I haven't tried other DV/firewire software other than WinDV so wouldn't know other options, but I do recommend you stick with firewire and WinDV if it can work on your system.

Delivery is what you encode to for playback. This could be MPEG-2, H.264, DivX, Xvid, etc. - it doesn't matter as long as you keep the Source. Understand that re-encoding, or de-interlacing, is destructive. However, it doesn't matter much unless it plays on what you want it to and you have a copy of the Source. Options change all the time for playback, maybe even yours will too a few years later, but if you have the DV Source, you will always have the highest quality options.
If PLEX can play the DV directly, great, go ahead and use it. Otherwise encode it to a format that can be playable on it (as long as you keep a separate copy of the Source). You're going to have to check on the formats of your system, or someone else can help here.

With editing, DV is among the best, and any consumer editor worth its salt can handle it properly, including lossless cuts and joins. DV is an intraframe format - edits should be a breeze.
For playback, use whatever is convenient for you, which would be for PLEX. It doesn't matter, as long as you keep the Source.I hate VHS. I always did. -
Thanks. I did mean firewire - I was typing on an Android phone with SwiftKey and it autocorrected to "firmware" ... which I verified when I made the correction and it did the same thing.
I understand about keeping the source. Once I get the pure copy on my computer, I will leave it unchanged - I will always keep that copy no matter what forms I create with it.
I also understand that you are saying DV is the best, and it is the original format that Digital8 uses. However, it can be difficult to know that I have a 1:1 DV copy when the transfer is done. What is a good (free, if possible) program to use to determine what the format of a file is?
I have captured in what appears to be DV based on the file description, but the video on my computer looks jagged/blocky, kinda like an 8-bit video game, but not nearly as bad. I am using VLC Player to play it back, and I am watching it in the minimized window. I thought it may be because my screen resolution is at 1920x1080, but the video is 720x480 (Digital8 native resolution). Is there some other reason for the poor quality?
Also, when playing the video through VLC Player, there is no date/time stamp/metadata, though I know it is supposed to be coded into the original. Is there some way to find it, or get it to show up in the transfer?
Also, can WinDV divide the files by stops in the original recording? Having one long file with months of separate clips can be hard to manage when you want to watch a specific event.Last edited by Slovey; 3rd Jan 2014 at 14:02.

DV timecode is embedded metadata and does not play on screen unless you have software that can do that. Try enosoft dv processor. WinDV will break the file down into clips as it's capturing if you set it to do so.

smrpix - I wasn't looking for the timecode on the screen. In VLC Player under "media information", you have the option to see the metadata as well as the format and other info. No metadata shows up. According to VLC, the file is DV, but there is no metadata that I can find. I didn't know if it was embedded in such a way that a player has to be coded specifically to read it.
I only need to see the timecode/datestamp so I can label the file accordingly. -

Don't forget that when you are playing the transferred (not captured if it is DV-AVI as it is just that, a bit for bit transfer of the digital data from the tape to the hard drive) footage is that what is recorded on the tape is interlaced and not ideal for viewing on a computer. If you were to watch it on a TV it would look a lot less blocky. Some players handle interlaced footage better than others too.

I would think Richard_G's post has interchanged the word "transferred" with "captured" maybe accidentally. Just an assumption.
There are theoretical definitions for "transfer", "capture", "encode", "conversion", etc, but in common language much depends on context.
Or maybe he thought you captured it into a different format (other than DV)?
Or maybe he thought you thought that the interlacing (the "raking" effect) from the DV video was a form of bad quality, which you don't see on other displays that handle it differently.
Would be valid points, but maybe he'll explain more.Last edited by PuzZLeR; 5th Jan 2014 at 02:49.

Doesn't Windows Media Player play it just fine? It does here (Windows 7).
If it works, use WinDV. I do. Use something else if you get lost audio, or dropped frames at any unrecorded breaks in the footage.
I used to use WinDV to split by scene, but then I decided to check for errors before splitting.
Now I capture (which in the context of DV is just a transfer) to one whole file first, then use this to check for errors...

...then use this to split into scenes...

Hope this helps.
