    You're right: 2.40:1; I mispoke.  What settings should I adjust here for this aspect ratio?

    In most cases you will not really see any difference in the aspect ratio. However, if you are a perfectionist and willing to trade off encoding/decoding efficiency for a more precise aspect ratio setting, then before switching to the "Custom" pop-up:

    a) Decrease the Modus setting to "4"

    b) Click on "Width" change button until anamorphic Width x Height settings are 1280x532

    c) Switch to the "Custom" pop-up

    d) Now decrease the anamorphic Width setting to "1024"

     

    Main Video screen should now indicate a 1024x532 anamorphic encode with a display of 1280x532 giving you a more precise aspect ratio of 2.406015:1 at the expense of efficiency/time required for encoding/decoding the data.

     

     

    And I am still confused about which default to start from and then add your suggestions above...

    I start with a "custom" preset. Actually, I have several:

    TV2 (Basic ATV2 preset modified with slightly increased quality with minimum video noise settings for old B&W DVDs)

    TV2+ (Basic ATV2 preset with increased quality, motion prediction 32 and no decimate settings for modern color action DVDs)

    TV2++ (Basic ATV2 preset with increased quality, motion prediction 48 and no decimate settings for BDs)

     

    I.e., TV2++ refers primarily to settings depicted in the "Advanced" settings image and to Constant Quality setting of 16 in "Video" Tab main screen image. I posted the images so you would know exactly what settings were used and could enter any changes as needed. I then stated the changes to the images that I would use for maximum compatibility with iPhone 4s, iPad2, iPad3, TV2, and TV3 devices currently in use. I only create one file for all devices since I have about 1,000 movies and 250 TV shows with thousands of episodes on my RAID drive at this time. (I.e. except for BD 3D discs, my entire video library which partially fills one bedroom upstairs, is backed up on my computer system for daily use while the original discs act as my archival copies for use if/when needed again. This arrangement protects my library from damage by visiting grandchildren and a wife who tends to think of my discs more as coasters for drinks than collectable media spanning 80 years of film and TV history.)

    It appears to say: "ATV2++" so does that mean you started with ATV2 and then made these changes?

    The other way around. Basically, I modified my settings to create the settings posted in the images and am now telling you how to modify them back to the "best" settings for my use. "Best" is a relative term and what is best for me may not be best for your purposes. That is why I told Thomas to run his own test to determine what worked best for him on his system. More over, compressing data is more of an art that a science. Each video should be treated as being unique if you are trying to get the highest quality results. Many of my videos have been recompressed several times starting with 320x240 files for my original iPod Classic 5th gen device and moving upwards with each revision by Apple providing higher resolutions and playback standards for revised and new devices.

    What no MPEG-1 VCD's?

     

    Any classic TV that is collectible?

    Making or buying? Never really purchased any VCDs. Started out collecting tapes and moved on to replacing them with DVDs. From there I switched to BDs and am now adding BD 3D content to my library. Unfortunately, the TV is not BD 3D display compatible which is why I they're the only form of media I currently view from the original disc at this time.

    Have any rare ones that are not generally available on home video/DVD?

     

    My AppleTV3 just arrived!!! 

     

    YES: I both purchased and burned VCD's in the old days! Then started burning my collectable VHS' and Laserdisc's to DVD...

    Everything I have is available to the public/was purchased on the open market. The problem is that many of the things I want are in the "lost" category— missing episodes of Doctor Who, Tomb Corbett, Rocky Jones and similar TV shows, as well as, "lost" Charlie Chan movies, "lost" Little Rascals shorts, etc.

    The good news is I have ordered the converter box so I will be using the Toslink cable starting Friday!  I didn't realize how big of a difference that would make.  Wish I knew sooner.  Are you saying in videos where you used the Toslink, these sync problems do not happen?  I wish I knew that sooner.  Should I still do the test since I will be doing it the other way soon?

    Confused as to what you mean by "the converter box" here. Thought Michael had said you were using the Hauppauge 1212 PVR for capture. Even re-wired my unit for direct component/Toslink connection and by-pass the Fury III so as to better simulate what I thought was your work flow.

     

    Main reason for using Toslink for me is to capture AC3 DD5.1 content when available. (I.e., while much of the content from my sat receiver is two channel mono or stereo, "prime time" shows frequently contain AC3 DD5.1 content.)

     

    As to the prevention of sync problems, that depends on your work flow. Most of the ones I employ contain an audio resampling operation. For instasnce, VoltiacHD turnes the M2TS file into separate audio (AC3) and video (MPV) elementary streams. This audio file is then converted to a re-sampled WAV file. The WAV audio and the MPV video are then combined in a temporary file which is probably AIC/Uncompressed since its size is the same as the final output file if I use the the VoltiacHD "Convert" pre-set option. In any case, this temporary file is what is used internally to convert content to other formats such as TV targeted content and is why using VoltiacHD takes so long to convert files. (The experimental  "Faster Conversions" option bypasses some of the steps to perform faster conversions but is probably also why this option is not compatible with some conversions.)

     

    As to your own sync problems, I think they may be caused because the source file used for editing contains independent VRB video and VRB audio components. When you cut a fixed number of video frames from this file, it removes the same number of audio frames but they may or may not correspond to the specific video frames removed. That would explain why the sync only changes following an edit but remain consistently "out of sync" until the next edit. You might be able to confirm this by the "CBR test" recommended. Whether or not you perform the test is up to you, but if you do run the test, I would appreciate feedback since I am falling behind running other tests having a higher priority at the moment.

     

    I do have the Hauppauge, but I have been using the regular audio cables to capture video because the new DirecTV Box does not have a Toslink connection on it.  Until I started speaking with you and Michael, I Had no clue there was such a difference.

     

     

    Okay, my turn to go "WOW!" File is a 720p60 Main Profile at Level 3.2 which is playable on the TV3. What I am excited about, is the fact that the file also plays on my TV2 devices which I had not expected. Basically, by capturing the source file as a 720p60 clip and processing it in HandBrake, you lowered the level to one that is playable at the current 59.94 frame rate. You could also have reduced the frame rate at the same time in Handbrake but this may introduce other problems commonly associated with changes in frame rate. As to random "stutter," I did not really see any when viewing in the "True Motion" mode on my HDTV, but this may simply be due to random dropped frames by the TV3 player. Basically, you are riding the playback limit here for the TV2/3 devices and I would consider this normal playback and probably provides superior playback consistency as compared to my clips with lowered frame rates. By using HandBrake first to make the files TV2/3 playback compatible, they can then be edited in MPEG Streamclip, saved in their current edited form, and played via the TV device as is. I tried the same thing with VoltiacHD using the built-in "Faster Conversions" preset but the problem with that work flow is the output was reduced to 960x540 for compatibility with all TV models even though the conversion ratio was reduced to about 1.5:1 (90 minutes for a 60 minute clip). I did have one complaint, however. Not sure if the problem was caused but the way you connected your RCA line or the result of your work flow, you you only had one active channel of audio in the GH05102012.mp4 clip.

     

     

    That is because I do no have the Toslink converter box setup yet. This is now what I ordered after some confusion: http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10423&cs_id=1042302 &p_id=2947&seq=1&format=2

     

    Is there a difference between editing in Streamclip and Quicktime?  I never knew it was possible and was wondering if I should attempt giving it a shot in there?  Oh, another reason I think I may have seen that flicker was because I did not have the Streaming option checked when I converted in Handbrake.  Could that be?

     

     

     

    Are you also in the South Jersey area? If so, are you a member of a local MUG (Mac User Group). I belong to SJAUG (South Jersey Apple User Group) northern division. We normally meet at Medford Leas on the 4th Saturday of each month if you are in the are and interested in attending. Also, if interested, here is a link to a copy of last month's newsletter:

    I am actually in Central Jersey, Hillsborough to be exact.  I had no clue such a group existed.  I would be very interested as I've only been full time Mac for about a year and have so much to learn.  I still can't figure out why I can't sort things easier, I could swear I use to be able to click on a column to sort by it but for some reason that doesn't work.

    Hey Jon:

     

    After two days of missing UPS (Apple always wants a signature and I forgot to leave it posted on the 2nd day), I was home all day Friday AND posted my signature just in case.

     

    Luckily I kept refreshing the UPS Tracking page and at 5:29pm (after being Out For Delivery since 6:44am), they posted Will Call at Office.  I called UPS at 5:49pm and they acknowledged the error and contacted the truck driver, who delivered my AppleTV3 about 30 mins later.  Glad I caught him...

     

    So, I was hoping that the AppleTV3 would play the raw output of the Hauppauge HDPVR-1212 without any transcoding, but with a simple container conversion to MP4.  Of course with only an AC3 audio track, I would have to listen to audio through my Samsung Home Theater (with no corresponding 2 track AAC file for compatibility with for example my Panny 42" Plasma - although since the HDMI cable should be passing the digital AC3 track, maybe there is a way I can get it to play on the HDTV, as well). 

     

    Later on, I'll start experimenting with possibilities of video passthru and audio conversion to AAC, so that I can quickly get a file that will play on the ATV3 without the delay of video transcoding.  Here are my results:

     

    My 720p file plays flawlessly, looks great and sounds great.

     

    The 1080i will not load into iTunes, so of course it will not play on the ATV3.

     

    Here are two analysies of each file.  Can you figure out why the 1080i will not load into iTunes?  Maybe I can make an adjustment that will allow the file to load:

    My 720p file plays flawlessly, looks great and sounds great.

     

    The 1080i will not load into iTunes, so of course it will not play on the ATV3.

    Rather than repeating what I have previously said, here is a chart depicting property limitations by Level:

     

    Screen Shot 2012-05-19 at 5.38.51 PM.png

    As you can see, High Profile Level 4.0 supports playback of 1280x720 playback at up to 68.3 fps but does not support 1920x1080 playback above 30.1 fps.

    I see, this chart is terrific: thank you!

     

    I guess I am forced to transcode, but as long as I have to do that maybe I can experiment on converting 1080i@59.94 to 1080p@29.97

    I guess I am forced to transcode, but as long as I have to do that maybe I can experiment on converting 1080i@59.94 to 1080p@29.97

    Setting the "Deinterlace" option for transcoding of your raw captures should reduce 1080i60 (59.94 fps) content to 1080p30 (29.94 fps) but may produce combing. Using the "Detelecine" option on your raw 1080i60 (59.94 fps) captures should reduce the content to 1080p24 (23.976 fps) but may produce skipped/dropped frames depending on how the content was originally telecined for distribution. Capturing in 720p60 (59.94) mode and not transcoding may produce smoothest playback as long as file container type is iTunes/mobile device compatible.

    That is good advice.  The HDCapture software for the Hauppauge has the MP4 container conversion option built in.

     

    It would be nice to figure out a way to add a 2 channel AAC track to the raw 720p@59.94 with AC3.  VisualHub (a legacy Macintosh wrapper for ffmpegx) has a video passthru option, but that program is a bit long in the tooth these days.  Handbrake, as far as I know, has no passthru option.

    Not sure if you saw my last post?

     

    Anyway, I am now setup to capture with the digital toslink.  Anything different I need to know while capturing?  I mainly capture from TV, 720p or 1080i.  I don't really do movies.

    As previously stated, my advice would be to try the various proosible work flows and decide for yourself which is the best for you.

     

    1) You can export the original capture to a 720p60 MP4 file container with H.264/AAC conpressed data using the software Michael mentioned, edit in MPEG Streamclip, and save the edited content using the "Save As..." option which does not recompress the data further. This would likely be the fastest work flow.

     

    2) You can export the source M2TS capture file (either 720p60 or 1080i60) using Handbrake and convert the file to an TV3 compatible file (720p30, 720p24, 1080p30 or 1080p24) st the same time, edit in MPEG Streamclip, and save the edited content using the "Save As..." option which does not recompress the data further.

     

    Both work flows have advantages and drawbacks which is why you should evaluate both work flows to see which best suits your needs and is acceptable with regard to the final output. Specific settings have already been discussed sot what you need to concentrate on is which work flow provide the size file you want with the playback quaility you can accept. Also remember that there is "no one shoe fits all" here if you are trying to get the best quality in the smallest package. Settings may have to be varied depencing on the quality of the captured source content and project requirements.

    This is what I did in the sample you saw.  I will post the settings I use to be sure they are right.  I have no clue what any of them mean, lol.  Gets so confusing.  Wish there was just a AppleTV3 preset.

Specific settings have already been discussed sot what you need to concentrate on is which work flow provide the size file you want with the playback quaility you can accept. Also remember that there is "no one shoe fits all" here if you are trying to get the best quality in the smallest package. Settings may have to be varied depencing on the quality of the captured source content and project requirements.

     

    I'm not really worried too much about file size, I just like to keep as much file quality as possible.  I wish I know how Apple makes the videos they have on iTunes!
