so need to convert/encode/whatever it is, for each video? and then delete the original file? i dont want that. i dont want 2 copies of similar movie either.
and i find it hard to believe u can convert/encode/whatever 56gb mkv under 30min. unless u use high end pc, which i dont have.
Seems like a lot of ppl misinformed
lets get into some jargons first. AVI, MKV,MP4,M4V,MOV,FLV,F4V etc..
for windows terms its called file extensions. In video/audio we call them containers. Containers is like a arrangement or format etc. Same concept.. doc.. docx..txt..etc. if u look at them in hex. u will find what u type. but u will find other arrangement, font settings etc for certain program to transcode it to a form of display u want.
so ok lets talk about h.264 video codec. Y cause its the most encoded format. All blueray runs a h.264 compression. so it is quite native. the question is just the baseline , high profile etc. All this is to reduce the file size to maintain some amount of high quality.
its so widely supported than even cctv DVR's, Online streaming sites etc all use it.
ok and which is the most popular codec for h.264 is mpeg-4 level 10 called AVC. Advance Video Codec. It has many options like cabac, b frame, etc etc to inrease the quality and maintaining low size.
ok so which encodes we should download. Of course the most popular and normally its the first encode. MKV's.
As i said all the DVR's are using h.264 also nowadays. When u see series etc. It comes into MKV first. and then only AVI container.
MKV has a lot of benefits. So does M4V. Only con i can find so far with M4V container is
MKV supports multi audio like TRUEhd, DTS, Dolby Digital, MP3,AAC
M4V supports only AAC, Dolby Digital.
M4V is Apple patent tech. Ok y only those two audio's. Cause its fast and easy for streaming. So they are looking beyond just watching it on a ipad or apple tv.
so in a mkv. Video is AVC. ( So just copy it)
Audio is normall DTS,TrueHD or Dolby Digital (AC-3). ( btw most series are in either DTS or AC-3 Dolby Digital. Just have to make it to AC-3 Passthrough)
So u just need to reencode this.
Also another con m4v. MKV afaik supports High-10p h.264. Quality on this is excellent and smaller size. This should be standard soon as its becoming more and more popular.Currently mainly used in animes. m4v has issues with playback on this but thats more of a hardware or quicktime software limitation.
So on a 50gb rip a dts audio or truehd for example is around 5k bitrate only.
a norm 10gb rip is around 1536bit on dts.
Thats y it doenst take that long. Y some computers are slow. Cause of the HDD speed. Say a Western Digital Black. It read and writes say 120mb/s. for a 10gb file to take out the video codec and then put back say 8gb on that..takes about 2 min 30 sec. Say on a raid ssd sata 3 setup. Thats just like 16secs. So most of the time transfering files to native formats etc and then putting back all the codec together into the m4v container is the one that takes most of the time.
whats the different with mp4 and m4v. m4v can support second level metatag, multi audio, multi subs,chapters
Again remember it just a container. A way of arrangement and coding for a software to read.
btw for subs. its damn stupid. Apple prevents most norm encode by just changing the hex handler for subs to sbtl. Only then it can read it. No idea y they did this. Maybe trying to be different. If they didnt. Most would find it damn easy to install subs
Oh yeah another con. mkv supports multi format subs. M4v only supports GPAC. for those who know subs. Basic of all subs is the srt format. The other formats has higher support etc like fonts , color etc. GPAC is like a XML format of srt which just tells the position etc on the video. Y this is a big con. BD's rips are normally in PGS.
try the easiest of them all. Avidemux. Just set video to copy ,Audio to AAC-aften choose stereo. and choose container mp4. try a mkv file. See how fast that takes.
Added on August 10, 2012, 12:08 am After reading this Please Show ure middle finger to all the paid apps who says need to reencode nonsensebtw hence y handbrake is mainly primary for dvd encodes only.
y again cause dvd's are not h.264 native and is limited by 480p. When u change it to a advance codec like h.264 compression u can get near dvd quality at 1/8th the dvd file size. or even divx which also is a mpeg-4 but again not as advance as a h.264 on compression tech. so thats y most dvdrips are in avi container using divx or xvid codec.
if u guys start doing this. U will realize how fast m4v is and how great the ipad video player is. Its damn good and plays damn high quality AVC that most androids has a lot of issues with.
