Should you have no other test file to test the batch conversion on, I recommend duplicating the above file with slightly different names and, having finished this, dragging the whole bunch of files to the app – it'll also prove unattended batch (mass-conversion) mode works as intended. The file has, being an unaltered, original DVD rip, an MPEG-2 video track you'll need to convert to the iOS- / Apple TV- (and storage-)friendly H.264. Say we need to preserve all the additional tracks of THIS direct DVD rip file (also linked to in THIS DVD ripping tutorial). Start the app and drag-and-drop the set of files you'd like to convert. (With its bother, MP4Tools, you don't need to do the same – there, it's the beta that you should use for most purposes.)
#Mp4tools failed license#
To mass-convert files to MKV, you'll need to purchase a license for the app and, assuming you do want to reencode the video track, download the regular (non-beta) version of the app.
#Mp4tools failed mp4#
(Actually, the main difference between the two is that MP4Tools creates / changes MP4 files while MKVTools MKV files when converting, from any kind of other file type.) Its brother, MKVTools ( homepage), has the same user interface and very similar capabilities. MP4Tools is one of the video handler apps I recommend the most for, among other things, remuxing MKV's to MP4's, joining more than one MP4's into just one target MP4 and the like. Therefore, we'll need to stick with the commercial (but still very cheap) MKVTools for mass conversions. Note that, unfortunately, HandBrakeBatch (as opposed to HandBrake), the most recommended tool for mass (batch-mode) MP4 / M4V audio/subtrack preserving (see section 2.2 below) can't output to MKV files, only mp4/m4v ones. It essentially instructs FFmpeg to add the “ m2ts” extension to the original filename of the input file to save the converted file to.Ģ, Batch converting any files to MP4 / M4V / MKV's with preserving all (subtitle / audio) tracksĪlso at MacRumors, I've been asked (post HERE and HERE) to explain how one can easily fix a well-known problem of HandBrake: for input files with more than one audio/subtitle track, the need to manually add every single (with DVD's, the original bitmap VobSub) subtitle and every single audio track to the target, converted MKV and MP4 / M4V files while, say, converting the video track from MPEG-2 to H.264. The second dynamic parameter set by the loop is "$f.m2ts". It's passed two dynamic parameters: first, the input filename itself (as was the case with Project-X), "$f", right after the input flag ( -i). Here, the FFmpeg executable is in the “ Contents/Resources/” directory of the “ Video Container Switcher.app” discussed in the above discussion thread. (Originally published HERE note that you can easily check out the context of the posts I link to by clicking the first “ discussion thread” link in the “ You are viewing a single post from a discussion thread on MacRumors Forums.” title above each post.) An example of invoking FFmpeg for a quick remux (container change) with forcing (see the switch “ -bsf h264_mp4toannexb”) FFmpeg to add a keyframe before each converted H.264 stream to make it 100% compatible with the m2ts container:įor f in *.mkv do Video\ Container\ Switcher.app/Contents/Resources/ffmpeg -i "$f" -acodec copy -vcodec copy -bsf h264_mp4toannexb "$f.m2ts" done The (varying) parameter passed to the java interpreter is in “ "$f"”: it simply passes the just-iterated filename to the java executable.īased on this explanation, it's very easy to generalize this to even supply output filenames to apps that, say, require an explicitly given output filename (the above command only required an input one) to write their output to. ts extension (this is what the “ for f in *.ts do … done” part is for) and for each of them, it executes the middle part of the command, java -jar ProjectX.jar. Just enter the following at the (OS X or any kind of Unix / Linux) command line to mass-process TS files:įor f in *.ts do java -jar ProjectX.jar "$f" done
#Mp4tools failed update#
With the excellent DVB TS recording processor Project-X, I've already shown (see the update at ) you how you can quickly and easily extract the subtitle tracks from several TS files at once.
Should you want to mass-convert / mass-process a bunch of files in, say, a directory or of the same type, batch files can be of tremendous help. Some of the video converters (for example, Project-X or FFmpeg) (also) have a command-line interface (CLI). In the article below, I present you them all in an edited, more verbose format.ġ, Using batch files (or looping commands) with command-line applications
At MacRumors, I've published a lot of tips on mass converting videos to make one's life much easier when mass-converting several videos at a time.
