What program can batch convert video

Hello,

I have many video files that I'm trying to convert from *** to .mp4

Currently I'm using Handbrake which does a good job but getting it started is very tedious. In Handbrake I need to confirm and add to queue all of the files. When there are over 200 files at a time it takes way too long. If there is a way to not confirm all of the files please let me know.

What program can I use to just add a folder and have it automatically add all of the files to my queue?

Any suggestions?

Hi,

I'd go with the humble ffmpeg - it's my main work horse for this...

Wellness!

Handbreak can be used from the command line.

Code:

$ cd folder

$ for file in *;do handbrakecommand "$file" ;done

Tnx arizonagroovejet! I adapted this for ffmpeg:

Quote:

for file in *; do ffmpeg -i $file $file.mp4;done

and that works like a train!

Thanks!!!

Hello,

I'm trying this:

and getting this error:

Is my input wrong? I want to convert all of the files from the Mash directory to the MashHighProfile directory. I'll worry about the correct setting for the device later. First I want to be able to get it started.

i wouldnt use filenames with spaces...
else escape the spaces or put quotes around the filename.

not quite sure what you want for the input or putput filenames...

try this as a quick test:

Code:

ffmpeg -i input.avi -b 64k output.avi

Putting all the videos in the argument line won't convert them individually.
You would do that to append videos (ie cat'ing files together) or have more than one video stream.
There are a large number of presets for libx264 in the /usr/share/ffmpeg/ directory. You want to include
options to control the size, aspect & quality of your output. The generic options will give you a very
low bitrate small sized video as a result.

Experiment with the options until you get the result you want for your device. Then you can create a script that uses those options in ~/bin/
and if you have several videos to convert, you can call the script in a loop.

Bonus example:

Code:

Here is the ~/bin/vid2sansap2 script I use to transcode videos for my Sansa P2 player:

#!/bin/bash

videoin="$1"

videoout="${videoin%.*}.svi"

if [ -f "$videoin" ]; then

    mencoder -vf scale=480:272 -ofps 29.97 -ffourcc XVID \

            -oac mp3lame -lameopts cbr:br=128 \

            -ovc xvid \

            -xvidencopts max_bframes=0:quant_type=mpeg:bitrate=1024 \

            -af resample=44100 \

            "$videoin" \

            -o "$videoout" 

fi

It uses mencoder instead of ffmpeg. For 4x3 aspect ratio video I use "-vf scale=360:270" instead.
It's easy to include the script in a loop to transcode multiple videos.

Thank you

I'll try both ways later this week.

Hope I can get it to work soon.
