FLV to DVD

[JWest]

Hey everybody.

I'm having trouble burning my FLV converted file to DVD-R. I converted the FLV file to DVD Video NTSC movie (.mpg) with Any Video Converter. It converted fine and burned fine, but the quality isn't good. The video quality is bad because the converter made the FLV file at 320x240 into 720x480, and it won't let me change the video size. Also, the audio is off like a Japanese Godzilla movie.

Can anyone give me any tips to fix these problems?
Should I use a different converter?
What should I do?

Thanks!

1) use flvextract to separate the flv into avi and mp3.

2) then convert to mp3 to wav using eg. winamp's discwriter plugin.

3)load the avi and wav into your video conversion application.
avisynth and virtualdub are fine.

steps 1) and 2) are necessary to maintain A/V sync.
(at least according to my findings)

The FLV video file is 320x240. Can I make it bigger in VirtualDub without distorting the video and hurting the video quality?

When I try viewing the video file after using FLV Extract, nothing shows up. What is going on?

Please note that upsizing such video does NOT distort the video. It will just make present flaws much more visible.

You can suppress them using AVISynth with some decent filter chains like I did recently:

But it is not trivial to set up these filters.

EDIT: you have to install an FLV-Decoder.
ffdshow can decode FLV/H.263.

If using AviSynth at all, then DirectShowSource's convertfps=true parameter *should* keep the audio in sync. Always has for me - the only issue is if the original source is out of sync, something that does tend to be common with sources from sites like YouTube that originally had some other framerate which ended up changing during the upload process or whatever.

Also, 352x240 is a valid DVD resolution (as is 352x288). I usually make an encode of my own video projects at 2000kbps MPEG-2 and 352x240 in addition to the standard res encodes I do. The quality is roughly similar to what you'd get from a Video CD (albeit cleaner, although this does depend on what the original source looks like). An FLV source would probably mean even less subjective quality in that comparison. The end result also depends on what kind of TV you're watching it on.
