    AFAIK, the AVI container was never capable of handling variable framerate. So the indexing of the video for that container is likely different. I am not sure about your questions on audio. I have never done anything other than transcode the audio between formats. I have never dealt with stretching or compressing duration. I know that you have to deal with the pitch change then, but I don't know a lot about it other than what I have read on sites like videohelp.com or doom9.org. From reading, it seems like a non-trivial exercise.

    Obviously since I am using SD video, all of what has been said, does not apply to me. But thanks for the reply sanjonny.

    So yeah, I have downloaded VideoRedo and pointed KMTTG to where the executable is. KMTTG calls it when the vrj file is ready, but can't process it, asking instead for an mpg or .tivo file. I need to read some more on that.

    So I went back and just transcoded to an mp4 file, and ended up from a 1GB TIVO file to a 400 MB file as an mp4 file. I like that kind of reduction (obviously it stripped the commercials using Ad Cut and Ad Detect). So from an 1 hour file I ended up with just a 37 minute episode. THAT IS archivable. It sounds to me like it is. I'd rather keep the titles, and I don't know why it cut those, but... I just need to see if I can get VideoRedo to work.

    I have no Sync issues. I need to understand the profiles you speak of in ff_mpeg. So what am I doing when I encode using ff_mpeg, and then using ff_mpeg, decode > (Did that describe it?) Not handbrake profiles, but ff profiles. But are you saying that handbrake handles "batch files"? I USED TO right "batch files" in a previous LIFE, so that would be up my alley. Where do you place them? Also, forgive me if I incorrectly say encoding instead of container.

    I am just trying to save size, and trying to reduce the size of my archive.

    AVI, xvid and mp4 transfer SO MUCH faster using pyTiVo though....

    I mean, like I said, I've done this a bit. I've saved some stuff on DVDs using Roxio 9.

    I also have a hacked DVD player that will play ANYTHING. But that's not the point.

    Digital storage is dirt cheap, and I envision my storing of these programs for a temporary amount of time, unless it's a movie....

    One last question, what wrapper is better for reduced size, and to maintain the subtitles?

    Hercules67 -

    I use the hb_tivo_hd_crf but I changed the default quality from 21 to 24 to reduce the file size even more and don't feel like I loose video quality. I ran tests on one show from a quality of 20 - 26 to see what I liked/didn't.

    If you don't care about cutting commercials out I have my Auto Transfers setup and love it as once set up you don't have to do much with it. I ran into an issue with one show where it wouldn't transfer as there was a spot in the show that would freeze up but other than that not too bad.

    So with my above setting a 1/2 hr HD show went from 3.24 gb to 744mb.
    An hour show goes from like 7.7gb to 1.173 gb.
    I would really like a way to cut the commercials out with no work but no go. I have some kids show that work great with just comskip but other than that it is more of a manual thing to be safe.

    A typical 1 hour long program is approximately 46 minute of program content minus commercials. AdCut may have over extracted some content which it thinks is commercials.

    Personally, I let VRD detect the commercials and I can go through them manually and verify/delete them. VRD lets you jump from 1 'detected' marker to another. Pressing F5/F6 jumps to Prev/Next marker.

    Where do I get t2extract?

    PS. Thanks "cburbs", I'll try that profile....

    PS.2 My video drive has been set-up and working. My only limitation now is processing power on video files.

    Yes processing power makes a huge difference - I believe you are talking about video conversion here. If so I did a comparison on a few files. See below. I also have now jumped from a 4 core to a six core processor and that cuts the decoding time almost in half again.

    did a 5 minute test file a while back on 4 different machines for a handbrake encode –

    MSI Atom 1.6 – 2gb
    encoding job completed: 01:34:30

    Asus Pentium 4 2.8 – 2gb
    encoding job completed: 01:03:26

    HP laptop Pentium DualCore- 1.72 – 2g
    encoding job completed: 00:35:52

    AMD Quad Core 260 – 4gb
    encoding job completed: 00:09:54
    ====================================
    2.19gb file test
    AMD X4
    >> ENCODING WITH PROFILE 'hb_high_profile'
    encoding job completed: 1:22:20

    AMD X6

    >> ENCODING WITH PROFILE 'hb_high_profile'

    I have mine setup to pull certain shows off, convert them and then save them to my network. With videoredo could I edit out the commercials on the MKV files afterwards to save some more size on my network?

    First, you would do better to encode to a MP4 container than mkv as the former is directly compatible with tivo and can be pushed without transcoding again.

    Second, you should edit the commercials / verify the ad cut points before the file is encoded to mp4, not after.

    I usually let kmttg download and decrypt, do quickscan and run the ad scan. Saving the mpg and vrf files.

    When I have time, I load each vrf file in VR, check or modify the edits and then use VR to finish the files. VAP as an add on can automate the saving of the edited mpg and finish the conversions if you have tv suite. I use megui to complete the encode after the mpg files are complete as I prefere its capabilities over that of tv suite.

    I guess that's the part I still don't understand how to do. Can you explain or point me to a post that does? Thanks jcthorne.

    I wizzed through a bunch of steps in that posting in a quick summery. Starting from the using kmttg to download, how far are you able to get? Lets look at this one step at a time as I do no know of a complete guide posted anywhere for all the steps. Its not hard though. Let us know and myself and others here will give you a hand. One step at a time, doing it all at once just confuses things.

    Thanks jcthorne - you can send me a private message if you so feel inclined. I am slowly digesting 117 pages of the Forum.

    I am trying to understand, the different "Encoding Profiles" KMTTG has available on offer for me (keep in mind, I don't have a a TiVo Premiere yet, and I understand the differences in transferring stuff to iPods, Zune, etc...). Why HB (Handbrake) vs. FF (FF_MPEG)? And the individual profiles. And how do you change the frame rate as suggested from 21 to 24? For STD definition video which is for my use, which one is best, keeping in mind, I am not creating some great video archive.

    I have successfully transcoded with both, and by mistake using the HD encoding as well. I can't seem to get VideoRedo to work, and I definitely can't get CCExtract to work. Keep experimenting.

    Time to install a new update.

    Thanks moyekj for a great program :up: even though I am late to the party.

    For me Encoding was experimental and chosen in the end on what I liked and what worked in my multiple setup I have. I know I dug at this for a while to.
    Someone at one time posted that they liked the following - "I recommend using ff_tivo_sd for SD sources and ff_tivo_hd for HD sources."

    I actually ran a test a while back on a half hour show and did the following encodes:
    ff_h264_highrate
    ff_tivo_hd
    hb_tivo_hd
    hb_tivo_hd_crf

    In the end I liked the hb_tivo_hd_crf though mine is changed up in the settings a little to my likings and my setup.
    I store the shows so that they can be played on multiple devices in my household - Tivo/Oppo/WDTV Live Plus. I chose MKV because that is what my Oppo can read.

    This is where I get hung-up also.

    Also, I *like* to additionally change files to .avi (smaller footprint). Which of the three files offers itself-up for this conversion better? --

    1. mpg Output Directory (that's first pass transcoded ,from .tivo --> .mpg, right?)
    2. .mpg Cut Directory (that's the one w/o commercials, right?)
    3. Encode Output Directory (what is this file then?)

    Avi.net recognizes (#1) but not (#2) and (#3). What processing steps am I missing?

    I probably sound like a complete noob... Trust me, I am reading everything I can, and I have programming experience (but not in Java ** some Perl). I am just now learning this video stuff, and I've come a long way from what I knew.

    Ok on that part
    1) yes
    2) Correct as long as you have it setup/working correctly
    3) This is your final file output - say you select ff_tivo_hd as your encoding profile this is where the final file will be saved.

    I am not sure what you mean on your *.avi question.

    Because MPEG2 files are easier to edit and scan for commercials. Now that VideoRedo can handle H.264 video, it probably doesn't matter too much*.

    My workflow is basically identical to what jcthorne does.

    * VRD needs to be fed constant framerate video. VRD will not usually accept Handbrake transcoded video because Handbrake likes to output variable framerate H.264 files. That in itself might be the most important reason for you to edit beforehand. :)
