ffmpeg ntsc-dvd 30000div1001

10moy2014

i threw a video at ubuntu's bombomo to make a dvd and the default results were horrible. When i tried to play it on a dvd player the video kept stuttering and played real choppy.

bombono-dvd uses avconv ffmpegs replacement but some one forgot to tell bombono and ffmpeg to use the correct frame rate [-r 30000/1001].

since the frame rate in avconv was wrong the videos played poorly on a dvd player when burned to dvd.but worked okay on my computer. the only way to really test things was to burn a copy.

In part_3:i used [-qscale 3] to get the video small enough to fit a dvd. and the quality was not that bad for a standerd def tv.

the qblur settings and other settings are because the original source video was a mp4 before i turned it into a avi and then finaly a mpeg2 for a dvd. the blur settings i think are something i have seen in avidemux.

give avconv and bombono a try to make a dvd. ymmv. i like the gui of bombono dvd. your milage may verry.

bombono dvd has a better looking gui than DVDstyler

"dynamic band in decibels" is meaningless.
I think you may dynamic range in dB. I don't recall the actual numbers,
but for mono FM is is about 60-70 dB with a fairly good signal.
Stereo drops it to about 50 dB

+1 But the SOX command for compression can require a bit of fiddling, but once you find a config that works in your environment, it rarely needs further tinkering ...

Wow, after viewing those graphs you seem to have really nailed it nibus! Would you mind detailing some of the parameters you use?

7ek

I use this template:


sox.exe "%INPUT%" "%INPUT%_%DRC%db.wav" compand 0.3,1 5:-80,-79,-%DRC% -%LIMIT% -90 0.2

Where the variables are defined by the batch file. DRC is the dynamic range,
meaning the smaller the number the more compression is applied
(everything is squeezed into a certain amount of db) and
the limit specifies how much headroom to give sox.
The more headroom the less dynamic range,
but also you have to be careful with too little headroom because of clipping.
I spent a long time tweaking these settings to avoid too much pumping,
but it's still there on higher settings.

Here are the ranges that I have set in my script, from light to heavy:

1 - 54db Range / 3db Limit
2 - 50db Range / 4db Limit
3 - 46db Range / 5db Limit
4 - 42db Range / 6db Limit
5 - 38db Range / 7db Limit
6 - 34db Range / 8db Limit

#4 and 5 work good for action movies, and #2 and 3 work good for dramas or comedies
(generally).

However, sox is only the first part of the process. After sox I send the output
to WaveBooster which boosts it even more.

Here is the whole package if you want to try it out:
http://www.mediafire.com/?lkhrr97p94s4izp

Couple issues: you need to make sure the file you drag into
the command window doesn't have any spaces in it's file path.
Also, WaveBooster only supports 16bit, 44100hz wavs, so in eac3to you need to specify:

-down16, -resampleTo44100
