DVD to FLV?

[Wes Ide]

Hi all!

Short version: What's the best way to go from DVD to FLV?

Long detailed version:

I've been given the task of converting 12 DVDs of 45-60 minute presentations into FLV formats for a web player. I searched this site's guides for that conversion type and found this tutorial here.

However, the tutorial featured a MPG to FLV conversion and I did not see any method of direct from DVD IFOs to FLV.

Well, then I found AVS Video Converter and copied the largest IFO from each DVD to my hard drive (renaming them) and converted to AVI. The first one alone took an hour. When it was done and I previewed it, it had video but no audio. Wow! So I tried it again to convert IFO to MPG. This time I just did about a minute's worth of conversion, cancelling it and then watching the resulting video portion. Still no audio! Same thing again with WMV, it had audio and video. Sadly, it also took twice as long (two hours per each 45-60 minute DVD IFO).

My next step was going to be to convert from WMV to FLV - but wait! Turns out I messed up a bit...

Each DVD had a large IFO and then a secondary IFO of smaller size. I basically ignored this second IFO. But, when I previewed the WMV from my work, I realized it was ending prematurely as a result of my ignorance. So I grabbed all the smaller IFOs from each DVD as well and converted each to WMV as well with AVS Video Converter. Then I joined them with a WMV Joiner program. However, when I previewed it, I saw that, while the video remained consistent, there was a very brief hiccup of silence at the join spot. I used a different WMV joiner program but the same thing happened there, too.


So now I'm completely confused. Sure, I can join all these WMVs and have the hiccup of silence, but I really don't want that. Is there a method or converting a DVD (with both IFOs joining together) into FLV, either directly or by way of another video format (that will result in a fluid result devoid of problems where the two IFOs join)? How so? And is there a way to use my already-created WMVs and join them without the hiccup so I can then convert them to FLV, or do I need to start from scratch?

Thank you very much in advance!

Xvid4psp and avidemux can convert directly from dvd to flv. In xvid4psp choose to open the dvd and avidemux just choose the first main vob(usually VTS_01_1.vob).

And you can also convert to mp4 h264 video, see https://forum.videohelp.com/topic355179.html .

An IFO is a DVD-Video information file, it does not contain audio/visual material You're using the wrong terms.

Extract the video using DVD Decrypter (see guide at digitalFAQ.com for this). Once you have the streams, demux the audio and video. You'll need to re-encode AC3 audio to WAV or something like high-bitrate MP3 or MP2, for most FLV encoders to understand it.

Drop your video and audio into Adobe Premiere CS3 or CS4, and then export to FLV.

Baldrick's suggestions work too, although I don't consider those programs to create high quality FLV. Then again, I operate professionally, I've got higher standards than typical consumers/enthusiasts.

Just use h264 in mp4 if you want high quality.
