Script to reencode all files in a directory
Hello. I usually reencode many video files with this ffmpeg command or similar

Code:
ffmpeg -y -i -c:a copy -vf scale=720:-2 -c:v mpeg4 -vtag xvid -b:v 969k -r 25 -pass 1 -an -f avi /dev/null && ffmpeg -i  -c:a libmp3lame -b:a 48k -ac 1 -vf scale=720:-2,subtitles=1.srt:force_style='Fontsize=20' -c:v mpeg4 -vtag xvid -b:v 969k -r 25 -pass 2 /.avi

So I would like to insert the parameters of this ffmpeg command on a script that reencodes all the videos on a certain directory. I tried to adapt a script that I found for it

Code:
for f in $(find -type f -name *.mkv); do ffmpeg -n -y -i "$f.mkv" -vf scale=720:-2 -c:v mpeg4 -vtag xvid -b:v 969k -r 25 -pass 1 -an -f avi /dev/null && ffmpeg -n -i "$f" -c:a libmp3lame -b:a 48k -ac 1 -vf scale=720:-2,subtitles="$f.srt":force_style='Fontsize=20' -c:v mpeg4 -vtag xvid -b:v 969k -r 25 -pass 2  ".$f.avi" ; done

However, when I try to run this script. it says that cannot find such file or directory. This happens because its treating every word separated by a blank space of the file's name as a file on its own.

So how can I solve this question. Also warns about any possible errors that might arise are welcome. Thank you

avimerge

avimerge(1)						      General Commands Manual						       avimerge(1)

NAME

       avimerge - merge several AVI-files into one

SYNOPSIS

       avimerge -o name -i file1 [ file2 [ ... ] ] [ -p file ] [ -a num ] [ -A num ] [ -b num ] [ -c ] [ -f commentfile ] [ -x indexfile ]

COPYRIGHT

       avimerge is Copyright (C) by Thomas Oestreich.

DESCRIPTION

       avimerge is a  versatile tool.  It can contatenate several AVI files into one. It can also be used to fix an index of a broken file and can
       also replace audio tracks or muxes new ones. It can read raw AC3 and MP3 files for multplexing.

OPTIONS

       -o name
	      Specify the name of the output file.

       -i file
	      Specify the name(s) of the input file(s) to merge into the output file.

       -p file
	      Specify the name of the audio file to multiplex into the output file. The type of file can be either another AVI file or an MP3 or
	      AC3 file.

       -b num Specify if avimerge should write an VBR mp3 header into the AVI file. Default is dependent on the input file (and usually correct).
	      num is either 1 or 0.

       -c     Drop video frames in case audio is missing [off]
	      Only when merging multiple AVI files. Some AVI files run a little bit (usually for one or two video frames) short on audio. This
	      means avimerge cannot keep up sync when concatinating them. The files play fine when played individually but not when merged because
	      audio from the new file gets played back with video from the old file.  avimerge will print a message like

		No audiodata left for track 0->0 (59950.25=59950.25) continuing ..

	      When you turn on the -c option, the video which is too much will be dropped.

       -f commentfile
	      Read AVI tombstone data for header comments from commentfile. See /docs/avi_comments.txt for a sample.

       -x indexfile
	      Read the AVI index from indexfile.  See aviindex(1) for information on how to create such a file.

       -a num Specify the number of the audio track you want to use from the input file.

       -A num Specify the number of the audio track you want to use in the output file. If you specify an existing track number, the track will be
	      replaced. If omitted, the next free slot will be used.

EXAMPLES

       The command

       avimerge -o big.avi -i my_file1.avi my_file2.avi my_file3.avi

       merges the three input files my_file[123].avi into one big AVI-file big.avi.

       avimerge -o out.avi -i in.avi -p audio2.avi -a 1

       merges track number 1 form in.avi to the next free track number in out.avi. You can create audio-only AVI-files using

       transcode -i song.mp3 -x null,mp3 -g 0x0 -y raw -a 1 -o audio2.avi -u 50

       The command

       avimerge -o out.avi -i in.avi -p sound.mp3

       merges the file sound.mp3 as an additional audio track into out.avi.
