Last year I offered to lend my DV deck to a friend. He told me he already had it.
I work in Manhattan, USA, but at night I cross the waters to sleep in Brooklyn, USA.

Also, post production is not an afterthought!

Must be what happened to mine, too. I vaguely recall lending it to a family friend to make DVDs of some home movies. I don't think I ever got it back.

From memory it should be identified as type .DV. If you rename it to .MPG or .MP2 you may have more luck. It may also work better for you if you link to it rather than transcode or copy.

If you can avoid unnecessary conversions it's a good idea. Renaming it to to .MPG should work. Try it with a copy of one file and see how you go.

I have used DVgrab to capture the video and then import them into lighworks. I haven't done this in 3 or 4 years, I think the output from dvgrab should be MT2 or something like that not .dv

There have been several issues reported by others over the time related to .dv files.

Although Digital Video should be standardized (somehow) there are different variants and it’s mainly a tape based format. There seems to be capturing software which produces formats not properly readable by Lightworks.

If renaming to MPG shouldn’t fix your problem, I’d strongly recommend converting DV with third party software (e.g. FFmpeg) to something properly supported. For further advice a Mediainfo report would be needed. Please see: www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=66072&Itemid=81

Or, maybe better: A short piece of a captured video downloadable at a file hoster of your choice.

I've a number of DV projects, but they have .avi or .MXF extensions.

DV comes to us in various containers (standardized or not). If the stream itself is the cause of the problem renaming won't help, remuxing may help sometimes, re-encoding will help most likely (if the transcoder used can demux and decode the stream properly, which isn't guaranteed).

I have some file from a Panasonic dating back to 2008. I use dvgrab to transfer them from the camera to the hard drive. You can use any of the following
dvgrab -a -f avi -opendml -timestamp Capture_Tape_1_ 
dvgrab -a -f mov -opendml -timestamp Capture_Tape_1_ 
dvgrab -a -f dv2 -opendml -timestamp Capture_Tape_1_

My case they were grabed as MOV; you have the choice of MOV, AVI or dv2. I am not sure if dv2 is importable.
Drag and drop will not work; but import does. and there is no problem.

So download dvgrab and try it.




My bad, I guess this Program is of no use to me, as I went back to the download page and downloaded a PDF and it says under the Windows are, that they removed firewire, so with no drag and drop or capture from firewire, this program is useless to me. I am going to uninstall it and be done with ya all

You should be able to re-wrap DV video to dvcpro and transcode the audio into PCM, into a mov container using ffmpeg. No video transcoding necessary. Lightworks can easily import this format.

Khaver: Just wondering if you can link me to a handy reference page listing the most often used FFMPEG command lines for converting/re-wrapping video.

I know this is an old thread, but like the original poster, I've also recently found myself wanting to import a bunch of old Mini DV tapes into Lightworks, and it seems to me that the best solution so far has been to use KINO (via Ubuntu) to produce .dv files, and then in turn to convert these files into something that LWKS can read. Tried jwrl's suggestion of changing the suffix of the files to .MPG, but alas, no love. So now I'm interested in re-wrapping the files using FFMPEG, as Khaver has suggested. Have heard so many good things about FFMPEG, but unfortunately, I'm a total newb at negotiating command-line apps. Can anyone help me with a simple command line to, as Khaver suggests, rewrap a .dv file to .dvcpro and transcode the audio into PCM, into a .mov container?

BTW: Have learned how to use <<ffmpeg -hide_banner -i capture004.dv 004.mov>> to do a simple conversion of a .dv file to .mov. Is this essentially the same thing as rewrapping, or should I be doing something else?

Khaver: Found a simple Youtube primer on FFMPEG, and I think I've figured it out. Used <<ffmpeg -hide_banner -i capture004.dv -c:v copy -c:a copy capture004.mov>> just to switch containers, which seemed to do the trick. Is this sufficient, or should I actually change the video codec to dvcpro in addition to merely changing the container? If so, then do you happen to know the suffix for the dvcpro codec? If I get that, I guess I can just try something like <<ffmpeg -hide_banner -i capture004.dv -c:v dvcpro -c:a PCM capture004.mov>> Right?

Okay, so now a quick LWKS question: Once I use FFMPEG to convert or rewrap my original .dv file, should I transcode it when importing, or is "create link" sufficient?

Stupid questions, I'm sure, but much of this seems above my pay-grade, I'm afraid. But I think I'm getting the hang of it.

<<ffmpeg -hide_banner -i capture004.dv -c:v copy -c:a copy capture004.mov>>

That's the one to use. I believe just re-wrapping to mov changes the codec designation to dvcpro. "Create link" or "Copy local" is sufficient.

Very cool. Thanks much. Now, if I could just find a way to batch-convert the 100+ .dv clips that Kino spit out during the conversion process, that'd be something. : )

Hello,

Here you'll find the bash script I use: www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=121996&limit=15&limitstart=105&Itemid=81#196204

Edit: I merged your command line and my shell script. Assuming that you use it to remux .dv to .mov format, with your command line integrated, log files disabled, and destinations folder set to 'Remux', it looks like this.

#!/bin/bash
shopt -s nullglob nocaseglob
folder="Remux"
mkdir -p $folder
for name in *.dv; do
# FFREPORT="level=32:file=$folder/${name%.*}.log" \
ffmpeg -hide_banner -i "$name" -c:v copy -c:a copy -y "$folder/${name%.*}.mov"
done

The attached script assumes that ffmpeg is executable from the bash shell and, it needs flagging as executable after placing it into an executable path on your system. A good place for locally used bash scripts is ~/bin: askubuntu.com/questions/322772/how-do-i-add-an-executable-to-my-search-pathdv

By the way, that should be so fast with your 100+ clips that I doubt that there will be enough time to drink a cup of coffee until it's finished.

Yes, very nice. Thanks so much for doing this, hugly. This should save me a lot of time. I've said it before and I'll say it again: This is hands-down the best forum on the Web. Always helpful. Always informative. Everyone here is great. So appreciative of this community.
