Convert AVI to FLV movies

[Skirner]

I missing some .FLV movies for my handpicked Sega Genesis collection.

But i have the missing ones in .AVI

Tried a converter but it becamed all messed up in Hyperspin. The movie was way to big on screen and the top was the onlything visible of the movie in HS.

And the converter added some shitty scrolltext in the movie.

Any Suggestions?

The games im missing FLV's for:

Lotus II RECS

Quack Shot Starring Donald Duck

Streets of Rage

Sub-Terrania

Tale Spin

Truxton

Wolf Child

Ys III - Wanderers from Ys

Zool

Premium Member, (waiting for Circo to update my profile)

I use IMTooFLV (shareware) to do Hyperspin AVI to FLV it does single and batch conversions. You can tweak bitrate, size, etc. Only 2 things - 1) It has a nag screen for registration. 2) It only will convert the first 3 minutes of your source. These don't affect this great program.

[Skirner]

Thanks, will try it out

I tried IMTooFLV and it keeps failing at the very end trying to convert the N64 AVI snaps to FLV. Have you tried to convert any of these?

You should be able to use AviDemux and a batch script to do the conversion.

Edit as needed...namely the CBR value...and of course the paths to the different folders and executable's.

@echo off
set Old_Dir=C:\Video Capture\Raw
set FLV_Dir=%old_dir%\FLV
set Run_App=C:\Program Files\Avidemux 2.5\avidemux2_cli.exe

if NOT exist "%FLV_Dir%" ( mkdir "%FLV_Dir%" )

for %%a in ("%old_dir%\*.avi") do (
	echo Converting: %%a to FLV
	"%Run_App%" --nogui --load "%%a" --audio-codec COPY --video-codec FLV1 --video-conf cbr=1500 --output-format FLV --save "%FLV_Dir%\%%~na.flv" --quit
)

I always just do a batch decode to uncompressed using virtual dub, then convert them to flv with adobe media encoder. Two batch runs and I am done.

[Nologic]

hmm I'm not seeing any benefit creating an uncompressed version...which is still going to be damaged already from the original encoding...unless AME doesn't like Xvid?

Plus this is just one batch run.

Xvid is not it's favorite.

If like me, you're not running a fairly new cpu, the 640x480 flash vids won't be smooth. You can resize them to 320x240, on a CGA tube, you won't tell the difference anyways. I use mencoder instead because avidemux don't have command line options for filters, and the API looks like a pain to learn.

just run this script in the directory where your avi files are.

#!/bin/bash


for avifile in *.avi ; do

        flvfile=`echo $avifile | sed 's/.avi$/.flv/'`

	if [ -f $flvfile ] ; then 
		echo "$flvfile already exists, skip..."
	else

		if file $avifile | grep -q "640 x 480"  ; then
			EXTRA_OPTS="-vf scale=320:240"
		else
			EXTRA_OPTS=
		fi

		mencoder $avifile \
         		-of lavf \
         		-ovc lavc \
         		-lavcopts vcodec=flv:vbitrate=1500 \
         		-oac mp3lame \
         		-lameopts abr:br=32 \
         		-srate 22050 \
         		$EXTRA_OPTS -o  $flvfile
	fi

done

hope that helps someone !

[Nologic]

codecrank thanks for the contribution...question thou are you running that in linux as I'm seeing bash and grep mentioned in the script?

Oh and mencoder is an excellent application.

[codecrank]

yeah I'm running it on linux, which I primarely use. ( my 2.6 Ghz core 2 duo can transcode a lot faster than my 2.3 ghz p4 running hyperspin )

you could adapt one of the batch files above to use mencoder with the options used my scripts.

mencoder is a great app in deed, just very cryptic, so I thought I'd spare someone from wasting an hour looking for the correct options.

[Nologic]

Thats cool, oh have you tried any of that new KMS support thats just gone in? I don't run Linux but certainly enjoy keeping track of its development.

Yeah Memcoder's CLI interface is very extensive while being very impressive.

So you are looking for something like this:

@echo off
set Old_Dir=C:\FLV
set RSZ_Dir=%old_dir%\RSZ
set Run_App=C:\Program Files\mencoder\mencoder.exe

if NOT exist "%RSZ_Dir%" ( mkdir "%RSZ_Dir%" )

for %%a in ("%old_dir%\*.flv") do (
	echo Converting: %%a to Resizing
	"%Run_App%" "%%a" -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=1500 -oac mp3lame -lameopts abr:br=32 -srate 22050 -vf scale=320:240 -o "%RSZ_Dir%\%%~na.flv"
)

I run nvidia's proprietary driver, no KMS possible for it yet due to lack of docs from nvidia. Works on Ati and intel video chips.

I work closely with cutting edge linux application programmers, it's about time some a serious video susbsystem overhaul on linux. As a sysadmin, I find X's network/client design very useful, but it lacks behind windows and OSX in the graphic department... and we considered switching to windows or macs for our high end graphic apps. But overall OS stability and versatility won

So I hope I'm not shooting myself in the foot by choosing windows for my mame cabinet. it's my first one. I already have a feeling it's not going to be the only one...

[Nologic]

Oh more than likely you'll be fine with windows.

Oh my revision of your script for windows doesn't test the resolution of the video...but I could certainly add support for that...but the script would have to be redone in AutoIt. Course if thats done...I could add recursive searching and converting...if you have the extra room on your HDD and what a near effortless batch process.

[codecrank]

I put that check in there because otherwise, videos of games with a vertical screen layout ( ex 1941 ) would get all squished if resized to 320x240

[Nologic]

Well so far I'm not finding a way to grab the resolution directly with AutoIt...hopefully there is an option somewhere in Memcoder to write resolution to stdout...at which point I can do something...other wise I'm coming up short right now.

Update 1:

Okay I found the following:

mencoder.exe "<Path>\<File>" -lavdopts vstats -o lavf

Which gave me the following:

No audio encoder (-oac) selected. Select one (see -oac help) or use -nosound.

Exiting...

If you can find something cleaner it would be most welcome, but I can work from this.

Update 2:

I've attached an AutoIt script that will do the same thing as your prior script, with the exception of doing recursive file search of sub folders...so keep that in mind or edit the script so that recursion is set to false.

This is source code rather than a executable...as I really didn't feel like making a GUI for it. So you'll need to have AutoIt installed on the system you wish to run it on...and you'll have to edit the path variable to where the Memcoder executable is...once saved simply double click on the script and it will execute bringing up a Select Folder dialog...once you have selected your folder, the script will run quietly in the system tray till its done at which point it will display a messagebox telling such.
