Video Formats¶
In choosing a video format, I went through a video format comparison and evaluation process to figure out what was best for me.
(If you want to see what settings I use to convert videos, check out the Handbrake page.)
Below is the current video format information; if you’re interested in why I chose them, check out the video format comparison.
H.265 Video / AAC + Passthrough Audio / MKV Container¶
As part of my switch to Plex for my media center server software, I also switched away from VIDEO_TS video format to individual movie files using:
H.265 video codec
AAC audio for the primary track codec
Native (AC3, DTS, etc.) audio for a secondary passthrough track
MKV container
I chose this format for three reasons:
Forward compatibility: While MP4/H.264/AAC is more compatible with my devices natively, as times change and tech updates, MKV is a more flexible format.
Video quality vs. file size balance: H.265 video, while slightly less compatible, has much better compression than H.264.
Audio quality: MKV supports any audio format, but a standard AAC track along with a secondary “passthrough” track with the original, unchanged audio for full surround is a sweet spot.
I use MakeMKV for ripping content from discs.
I use Handbrake to convert the ripped disc content into the target format. The Handbrake page shows the custom settings I use for video conversion.
Something I did notice as I moved away from VIDEO_TS into a new, “standalone file” sort of format, is that audio/video sync sometimes got off somewhere so lip sync was visibly bad. Sometimes this is due to the source material being bad already; other times it had to do with frame rate issues. I talk more about lip sync on the Handbrake page.
I will say that, from a container perspective, subtitles is an area where MKV definitely outshines MP4 - MKV allows multiple subtitle tracks, just like a regular disc; MP4 only gives you one, and whichever one you choose is “permanently turned on.” I talk more about how I handle subtitles on the Handbrake page.
I gathered some general statistics after I finished the mass conversion of all of my media using Handbrake that may help you gauge how much space you need. This is using the settings outlined on the Handbrake page. Note this was with MP4/H.264 compression - I’ve since moved to MKV/M.265.

VIDEO_TS Disc Image¶
VIDEO_TS isn’t really a “format” in the classic sense.
When you use a tool like DVDFab HD Decrypter to rip the content from a disc onto a hard drive and you want a full disc image - no compression or conversion - you have two choices. You can either get a literal byte-for-byte image in .iso format or you can get the files from the disc in their native directory structure.
If you choose the files in their directory structure, the directory that comes out is called VIDEO_TS. Inside that are a bunch of files with the extension .vob that are, basically, MPEG-2 video files.
I used VIDEO_TS format originally in combination with XBMC to both back up my movies and serve them at their original, unchanged fidelity.
However, MPEG-2 video is poor compression and eats up space. Also, you have to use a smarter media front-end like XBMC to play a disc image in VIDEO_TS format because it means the front-end must emulate a DVD player. Thus - it’s far less portable than other formats.
When my media center goals changed to go for more portability, I moved away from VIDEO_TS.
AVCHD / MTS / M2TS¶
I first encountered this format when I bought an HD camcorder. At that point it was sort of difficult to deal with - not much would play it directly and I spent some time trying to figure out how best to store it as something more compatible.
As it turns out, this is the same format in which Blu-ray discs are stored. More things play the format natively now, but I still end up converting these files (from my Blu-ray discs and my camera) into MP4 files. Handbrake is the way to go for conversion here.
For home movie editing in this format, I use Sony Vegas. I save my edited movies as MP4.
