comment How to Convert All The .MOV Videos To .MP4 in folder
You must be a conspiracy theorist. The qscale option uses the MPEG* linear quantizer scale which is used by several encoders including mpeg4, flv, mjpeg, msmpeg*, mpeg1video, mpeg2video, etc. Not by libx264. I did not say that ffmpeg or avconv ignores the option, but that libx264 does (as it should). You can test with and without the -qscale 1 option: avconv -v error -i input -an -c:v libx264 -qscale 1 -f md5 -. Does the MD5 sum change?

comment How to Convert All The .MOV Videos To .MP4 in folder
If -qscale is doing something then you're probably using the encoder mpeg4 instead of libx264 which will output MPEG-4 Part 2 video instead of H.264 video. libx264 is used unless it is not available, so mpeg4 becomes the fallback.

comment How to Convert All The .MOV Videos To .MP4 in folder
-sameq does not mean "same quality", and anyway it has been removed ages ago. -qscale is ignored by the encoder libx264 (at least with ffmpeg). If the mov inputs contains compatible streams then you can stream copy (re-mux) instead of re-encode with -c copy. FFmpeg is available as of 15.04, and Debian has decided to drop Libav for FFmpeg.

comment Joining MP3's via commandline with background track
No need for the extra step to convert the m4a to mp3 if you're using ffmpeg. Please show the complete console output of ffmpeg -i Audio1 -i Audio2.

@DominicIsaiah Please provide a pastebin link showing your command and the complete console output. What player did you use? Can you provide the input file?

@DominicIsaiah I updated the example to include the Desktop in the path to the input. See Ubuntu Wiki: Using the Terminal - File & Directory Commands for more info.

comment avconv uses only the first image in directory
Try a build from the link I provided. Just download, extract, then run. Navigate to the directory containing the ffmpeg binary, then run ./ffmpeg .... The real ffmpeg returned to Ubuntu in 15.04. The long absence was due to the maneuverings of the package maintainer who aligned himself with Libav and switched Ubuntu to this fork. It provides avconv and the counterfeit "ffmpeg" in earlier Ubuntu releases.

comment avconv uses only the first image in directory
Does a recent static build of ffmpeg exhibit the same behavior?

comment AAC to AC3 avconv failing on some Files
Your input Film.mkv appears to already contain ac3 audio. Why are you using ac3_fixed (fixed point) instead of ac3 (floating point)? At least with ffmpeg the floating point ac3 encoder will provide better quality. I'm not sure about avconv: I don't use it (does anyone?).

comment FFmpeg use AAC encoder
As for -qscale with no stream specifier, using it with a non-ancient ffmpeg build will result in various messages: Please use -q:a or -q:v, -qscale is ambiguous and [libx264] -qscale is ignored, -crf is recommended. For aac it is ignored as well. This can be confirmed by using the md5 muxer.
