    These are raw output files from the Hauppauge HDPVR-1212 and not run through HandBrake yet.  As you can see from the detailed file analysis above, it is 1080i.  I expected it to be 59.97 but was surprised to see it as 29.97.  Maybe MediaInfo Mac analyzed it wrong...

     

    I am sending you the sample file uploaded to YouSendIt.  You will receive an email with a download link.

     

    NOTE: the software has the ability to change the file from the m2ts container to mp4, which is how Tom uses the file in Streamclip.

    How do I set the Main or High Profile or Level 4 encodings? 

    "Context adaptive" means the encoder sets the Profile and Level as needed to meet the standards required for the encoded frame size and frame rate. In this case, a 1920x1080 frame requires 8,000 macoblocks which automatically forces the Level to 4.0 at a minimum and a video data rate of 20 Mbps or less at 30 fps or less would only require the Main Profile. If I want to use a lower Level like 3.2, I would encode the content anamorphically using a 1536x1080 encode matrix set to playback with 1920x1080 display screen.

    Converting the file to mp4 and opening it in QuickTime confirms that it is 59.94; so the file analyzer must be making the mistake...

    So selecting Context adaptive is all I need to do if I understand you correct?

    There is nothing to select. The application automatically sets the profile and level correctly if you simply enter the settings stated in my first response and remember to limit the data rate this time around.

    OK!  Can I post a screen shot of my settings for you to doublecheck?

    As previously stated, I normally use the iTunes window to pre-set the TV 1280x720 option for this window and then increase the 1280x720 (HDTV 720p) option to 1920x1080 (HDTV 1080i) before setting the "Deinterlace option. Also as previously indicated by not mentioning it, I do not set the Multipass option and do not overdrive the quality setting at 100%. These last two options may triple or quadruple your encoding time. So if you are complaining about extra long encode times, your wounds are self-inflicted.

    OK, here is a new set.  I did click the iTunes box and have the selected as demonstrated below.

    Oops, Deinterlaced should be selected below as well.

    Maybe like this?...

    Would this then result in 1080p?

     

    What about the frame rate?  Will the AppleTV3 play 59.94 fps?

    Are you going to now select the 1920x1080 (HDTV 1080i) option, select the Deinterlace option, increase the video data rate to 12 Mbps, and change the audio sample rate from "Auto" to 48.0 KHz @ 256 Kbps?

    Like this?  What about frame rate?

    I would still increase the video data to about 12 Mbps if the source file quality is worth it to preserve detail and up the audio to 48.0 KHz at 256 Kbps is the source audio is worth it. The idea here is retain as much of the source content as prossible but it the source data is already below these levels, then it can be a wast of file space.

     

    P.S.

    Alternative work flow did not working. VLC re-wraps not liked by either QT or MPEG Streamclip. Have created a "custom" encoded test file in HandBrake which looked okay in QT test playback but have not yet tested it via TV3 playback...

    Tom wants to edit out commercials in MPEG Streamclip.

     

    He cranks his source up to full data rate available on the Hauppauge which is about 17!

     

    Audio encoding is usually AC3 passthrough from source - from the file analysis that I posted earlier, it looks like 48KHz at 384Kbps.
