Ok fellas here is my problem we just started using the recorder listed below, it records in Mpeg4 to either a thumb drive, Compact Flash card or a smaller internal HDD. On the card or thumb drive it shows up as an AVI, on playback on a computer it works fine as long as you have the proper codec. But when I put it to DVD for evidence it takes freaking forever to burn it using windows DVD maker. What I need is a cheap (free) program that I can both trim the video to what I want to put on a DVD and burn to DVD without it taking 45 minutes to burn an 1 1/2 worth of video. Any help from the Guru pool would be greatly appreciated.

evidence?
abby or mcgee from ncis can help you.








Without access to the video. I'd say you have a mpeg4 stream inside the avi container.



Avidemux can trim and append mpeg files together.  I use it when I make dvds from youtube videos.



I use DVDStyler to make the DVD image from the mpeg files.



and I use imgburn to burn the iso to the dvd. (dvdstyler can do that, but I use imgburn)





It is clunky, but it is cheap.

I'm no legal expert, but if I were a defense attorney, and I could show that you altered the evidence?



I'm just saying...

how about copying it to dvd (instead of transcoding it) and playing back on a laptop/computer in court? this escapes both the speed issue and the "you tampered with it" issue

well the problem is getting the courts to accept another format. We had the same problem when we recorded on Mini-DV we had to dub it to VHS and finally got them to get DVD capability. For the mini-DV we plugged directly into a DVD burner and dubbed it with no problems. I'm not really worried about the "you screwed with the video" aspect. If that were an issue just about every LEO agency in America would have a problem with Digital Photos. We are covered as long as we can testify that it is a true and accurate representation of the video we shot.

could you post an example video somewhere I could download it? Alternatively, if you can make one < 10 megs and like 10s long, email it to me - [email protected]

I'm looking for some editing software to cut a clip.

the thing is, I don't want a cut clip - I want an original file. Anything you cut will be (by nature) edited by the program you cut it with.

You can use a service like drop.io to send a larger file, if you like. This will take up to 100 megs.

so I was able to convert it to .wmv using Live Movie Maker Beta. VLC can also play it, no problem.

VLC reports:
stream 0
Codec: DX50
Language:
Type: Video
Resolution: 720x480
Frame rate: 29.97

Stream 1
Codec: araw
Language:
Type: Audio
Channels: 1
Sample rate: 32000 Hz
Bits per sample: 16
Bitrate: 512 kb/s

This means the original encoding is DivX 5.0. Here's the DivX site.

I had to download the codec from divx to play the file and when I play the video on my computer it plays in media player without a problem. would it be easier to comvert to wmv an then burn to dvd?

what's the goal here? to end up with DVDs that will play on a certain DVD player?
2/11/2009 8:07:13 PM EDT

Yes to play on a standard dvd. I can get it to dvd but the problem is the time it takes to get it in that format it takes an hour to burn a disk that is 45 minutes long (approx).

What I really need to know is if this is something I have to live with or is there a program that will do it quicker.

well, that probably isn't quite right. Firstly, it has to transcode from DX50 to MPEG2, then it has to burn.

You could check to see if your county/whatever has divx capable dvd players. You may laugh, but many of the cheapest dvd players out there will play divx natively. I'm talking the $20 wal-mart specials.

For the next part... I'm working on it. :)

I wasn't sure on the whole Divx thing we have a 300.00 dvd burner that won't play em so figured I had to go to the standard dvd. I will have to look into that. Oh by the way did I mention you are da man.

1) transcoding is a function of CPU speed. The faster your CPU, the faster the transcode.
2) burning is a function of your burner speed, media type, and CPU on the machine you're burning.

for me, I burn at about 8x - if I have to transcode first, it drops to about 2x.

So, just to make this public:
I used this guide using this software to convert this video into DVD format. On my computer, it ran about 2x for the transcode - so a 20 minute video will take 10 minutes to transcode.

I ended up with a DVD filesystem in some directory. You can use any of numerous burning software to straight copy the files over to the DVD and burn it. If your burner came with something, let's hear the name of the software so we can work on a step-by-step to get it up and running.

one could ffmpeg the video to the dvd format.





I'm a fan of ffmpeg

btw, till something more reliable comes along.



edit: audio looks to be uncompressed mono with a fairly good quality.
