If you're happy using the Terminal, then you could try the following command loop: for f in *.flac; do ffmpeg -i "$f" -vf "crop=((in_w/2)*2):((in_h/2)*2)" -c:a alac "${f%.flac}.m4a"; done This will simply cycle through all the .flac files sitting in the current directory and convert them all to .alac until they're all done. I can confirm that this works ...

X Lossless Decoder (XLD) is a great prefect lossless ripping and batch conversion tool for the Mac. I've heard great things about getting perfect lossless rips using Exact Audio Copy (EAC) on Windows, though I'm not sure if it supports conversion.

Look at ffmpeg. It will run on just about anything and should do what you want, although it might depend on what your source actually is Something like this should work : ffmpeg -i sourcefile.avi -f image2 'img-%03d.jpeg' (see the image2 section for full reference)

For a good GUI based on libavcodec (which a ffmpeg library), take a look at handbrake. Might be a bit too detailed for a very "simple" user, but with some effort it's manegable. It also supports saving of presets, so you can set it up for easy use.

-profile baseline seems to work for me, using libx264. I use the libx264 presets - for example "slow" gives me the options listed below. there's fast, slow, veryslow and placebo (might be more, can't remember). stib$ ffmbc -i test.mov -vcodec libx264 -preset slow -profile baseline -acodec libfaac -ab 96k -crf 19 test.mp4 ... [libx264 @ 0x101858c00] profile ...

Note: This is for recent FFmpeg, not FFmbc, which doesn't use the same option syntax (yet) You need to use the -profile:v option, which has been introduced in FFmpeg 0.9 (afaik) and is now standard in 1.0. ffmpeg -i input.mp4 -c:v libx264 -preset fast -profile:v baseline out.mov Why? -profile was used (and prioritized) for AAC encoding. It's simply ...

if you want convert everything flac file in folders and subfolders recursively add the /r to the for loop command like so: for /r %%a in (".flac") do ffmpeg -i "%%a" -acodec alac "%%a.m4a" -map_metadata input.flac:output.m4a The only problem i have with this is that filenames come out like output.flac.m4a I have no idea how to fix that at the end, but ...

1) If you're not going to deinterlace it then stick to the source's field order. 2) I wouldn't bother with the two pass encoding (if indeed it even does anything) - dnxhd will only encode at certain specific fixed bit rates anyway so you're actually pretty constrained for options. 3) You'll see some softening, but it's unavoidable. ffmbc's filtering is ok ...

You could create a droplet in compressor. Unfortunately, your options for destination folder are limited by this method to either source, desktop, cluster storage, or your movie folder. Since you don't want your watch folder endlessly copying movies, "source" is a bad choice, and you probably don't have cluster storage, so as long as you're ok with your ...

I do this all the time for local user groups and I'm yet to find a "plug and play/set and forget" solution. To do the recordings at a professional quality, you need some sort of skill and training, otherwise it will look amateur. If all you want to record is the person talking, and not what's on their screen, it's relatively easy: buy a wireless lapel mic ...

The JPEG 2000 codec in FFMPEG is still experimental. To use it you would have to compile FFMPEG by yourself with a special option enabled. But you could use OpenDCP, which has it's documentation here. It needs TIFF images and WAV files as input, that you can produce with FFMPEG. The resulting MXF can be tested with the easyDCP player. OpenDCP is available ...

I went to the FFmpeg site to download the latest ffmpeg Win32 from 11/20/2012. You may need 7zip to extract the EXEs and place them in a path that is recognized. Still can't figure out how to recursively run the command. I've tried using an old DOS command called sweep and also forfiles -s -c but neither work correctly. I ended up generating a list of ...

XRECODE does a great job of batch conversion. I'm pretty sure it is just a front end for ffmpeg. It keeps your tags and embedded images (for most formats - see this answer for exceptions) during conversion. The current version has a non-expiring fully functional trial (complete with nag screen), but you can download the previous version for free. I ...

There are a wide range of applications for Windows and for OSX - you could try Audio Transcoder or Max or a range of others (google will find many) Or you could convert FLAC to WAV and then let iTunes do the rest
