Proprietary format

Hi,

I am looking for a good but not too expensive solution for analog video capture (Hi8). After fooling around with a G400 + RRG card for the past several weeks, I was looking for another possibility and came across the DV.Now AV card. From what I have read so far, it almost looks too good to be true. Hardly any complaints, and a "final" solution in sight (Premiere 6; no audio problem).

What worries me, however, is the proprietary format used for capture. It seems, and please correct me if I am wrong, that this format is useless outside the FAST software that comes with the card. Is that true, or can the captured file be used elsewhere, i.e. with the Windows Media Player, etc.

How good is the scene detection? Are these individual scenes available as separate clips, or only as part of the whole captured file?

Thanks for any comments.

The DV Now.AV captures files in the FastDV codec using the .dif extension. This seems to be some sort of Quicktime codec as the files can be read using Quicktime. It's partially true that they are a propreitary format, but they can be edited and used in Premiere. You can also output the files from Premiere in whatever standard format you choose such as .avi, .mov, .mpg. Therefore the whole "propreitary" thing is a non-issue.

Mike is absolutely right about FAST DV format - it can be played in Quicktime Player but not in Windows Media Player.

The scene detection works as follows:
It rewinds the tape to the beginning and then plays it from beginning to end, detecting every point at which the camcorder was stopped and started during recording. These points are treated as scene changes.

At this point the video in not being captured - the clips are just being logged. The log of each clip/scene shows the first and last frame and the timecode information. You then select which of these logged clips/scenes you want to capture and then just batch capture them.

If I understand you correctly, this works only for digital cameras, or do analog (Hi8) tapes also provide the necessary information?

This feature is only for batch capturing, i.e. it does not actually create separate clips for each scene?

Yes, the scene detection only works with DV capture. The analogue connections cannot carry the timecode or device control like Firewire can.

The scene detection feature only logs the scenes it detects and you then have to batch capture the ones you want. It does not capture the footage at the time of scene detection.

Scene detection that creates separate clips is very important to me, and I am surprised that it is so hard to find software that does it.

Are you aware of any software that does scene detection, either during analog capture or afterwards using the captured file?

There is a number of programs that do what you want, but all of them, I think, only work on DV and with cards that produce standard avi files.

Possibly the best example is Scenalyzer at:

Alternatives (which do work with analogue but not in the way you want, I think)
include AVI_IO - by Markus Zingg

and Thuyen Nguyen's ReelCap at: http://www.reelware.com

The feature you require, Scan Tape that captures as it detects scenes, is something that we have been asked for before. It is on the 'wish list' for future versions of the software. However, do not expect it very soon - it will not be in the next software version, 1.6, but may be included in a version after that.
