What's your average FPS during Blu-ray rip to Apple TV 2 in Handbrake?

    I'm just curious as to what FPS folks are getting when converting a Blu-ray-sourced MKV file using the Apple TV 2 preset in Handbrake. I'm getting anywhere from 17 to 22 FPS depending on what else I'm using my computer for at the time. I do have the decomb switch set, so that may be slowing me down a bit.

    I'm not sure if bd differ from DVD but my DVDs are typically averaging 45 fps, some go as high as 60 fps

    That's apple tv 2 preset with an rf of 19.

    I find that the fps depends on the disc and even perfect looking DVDs in a boxset can vary, some rip twice as fast as others.

    Sorry re read it and you are interested in MKV conversion so the above probably isn't helpful at all. I will leave it anyway

    Decomb will slow HandBrake down a bit, and there is probably no need for it with any material from a Blu-ray.

    I don't have my FPS info handy right now, but my Blu-ray to 720p m4v transcodes usually run at about real time (90 minutes for a 90 minute movie) on my quad core, 3 GHz Athlon-II "compute server". DVD conversions usually go at about 2X real time for me. (Both with unmodified AppleTV 2 preset.)

    What kind of machine are you running the transcodes on and how long do they take to complete?

    Right. Blu Rays and most modern (non-TV show) DVDs are not interlaced, so no decombing is required.


    Encoding Blu Ray to 720p for my ATVs will run at anywhere between 20-30fps, depending on the amount of on-screen action/detail. Encoding for iPhone 4 (544p) will run into the 70s on occasion.

    (See my sig. line for equipment)

    LOLOLOLOLOLOLOL sorry but at the moment I'm ripping a BluRay at about 6fps. So yes their is a difference between a 720x480 MPEG-2 DVD and a 1920x1080 BluRay/rip...big difference ;)

    I was referring to FPS differences not resolution.

    I've never ripped a BD disc and i have no idea what the read speeds are on drives or what decoding is needed.

    Obviously this varies dramatically depending on your hardware. I do my encoding on a quad-core AMD machine and average about 20 to 22fps doing said encodes. DVDs are blistering fast - but who uses those as a source any more?

    On my trusty old MacBook (late 2008) the same process is dreadfully painful at about 7 or 8fps tops. And enough heat to fry some eggs and bacon :D

    Mine isn't blue-ray but I figured it was still pretty good?

    Uh well resolution can make a big difference in FPS. I can rip a 2 hour DVD in less than an hour on my MBP...a 1.5hour BluRay on the other hand might take 4-5 hours if I'm lucky and not using 2-pass encoding. Just something to keep in mind.

    I just did some comparisons before the holidays on my core duo 2 mini server and my new i5 mini desktop and also my 24 inch imac with MKV 1080p blue ray rips. I was very surprised how much faster the i5 did over the core duo's. it was almost twice as fast. I was using the straight apple tv 2 preset and not changing anything. the core duo's were running between 7-9 fps, and the i5 was 15-18 fps.

    I guess I need to test out the no decombing and see whereIi get.
