Unusual encoding times?

hey kids,
I recently had to take 5.5 hours of DV NTSC footage and transfer it to DVD for a client. I thought that I could break it up into 2 DVD's at 2.75 hours each but the final mpeg2 files were too large for 1 DVD (6.7 Gigs). I had to divide up the clips again to fit 1.25 hours on each DVD (roughly). Which was fine for the client but the encoding ended up taking 5.5 hours each 1.25 hour clip. I'm on an old dual 1.8 G5 with 2.5 gigs of ram. I also encoded the media all on the same drive. These encoding times seem really long and I didn't expect them and neither did my client. Is this really normal?
Let me know if you need more info.
Thanks

Encoding on Macs is slow. Depending on settings used for encoding it can be really slow. Putting media on drives other than the system drive helps speed things along (and target for the encoded files on another drive can also help.)
5.5 Hours for 1.25 does not sound that far off the mark. Have not done recent speed tests (usually I set things up to encode overnight, just part of the workflow for me now when using the Mac to encode) but when I use bitVice the first pass is about 4-6 times realtime the first time through and from .2-.3 Realtime the second time through depending on the footage (Dual Processor G5 2 ghz). My MacBook Pro seems a bit quicker, but have not really timed in.
As an aside (and for future reference) I also run Paralells on the MacBook Pro and use CinemaCraft (Light Version, $50 or so) and get between 1.5-2x real time speed on each pass.
As to why Macs are so slow, got me. If PCs can get encoding going that quick on software, figured the Macs could also. Perhaps someone else knows some more of the details and/or perhaps the new Intel Chips will open up speed more.

  • Video Encoding Time

    My original video source is 1280x688, 2600 kbps bit rate and I wanted to convert it to Ipad maximum 1024x768 resolution. I used WinX HD Video Converter which has options to use ipad output.. It took 24 minutes just to convert 5 mins of the 90 minutes source... meaning, it would take over 7 hours just to convert a video source to ipad maximum resolution (lowering it would produce low quality video and you got an ipad to avail of its increased resolution). My output setting is 1000 kbps, video frame rate 29.97 and resolution 1024x768. Audio output is 128kbps, 44100 Hz. My computer is Core 2 duo 1.8 Ghz. How about you. What kind of computer do you use and how long is the encoding time? What settings do you use and most important.. what is the maximum video setting possible in the Ipad that can play it nicely or optimumly?

    I have a turbo264hd, use hadbrake, videomonkey.
    If it's hi def, I go with the turbohd.
    Try setting to 960x540.
    Good middle ground for high def stuff. You get no benefit on a 10" screen watching high def over a lower resolution with decent bit rate.

  • Canon AVCHD 30p vs. 60i, encoding times?

    I just picked up a new Canon HF-M41 video camera and am presented with the dilema of shooting in either 60i or 30p AVCHD. On this camera, the 30p is 'recorded' at 60i but saved as 30p.
    I am literally stuck on the frame rate selection screen of the camera, not certain which frame rate I should go with.
    I do most of my publishing to YouTube and to DVD. It seems like 30p would be a better format for me to work with natively on the camera, but I'm not sure how Premiere handles 30p from Canon. Since the video has been shot 60i and then wrapped as 30p, has anyone had enough experience with this to tell me if Premiere does a good job of handling this kind of video?
    Alternatively, if I stick with 60i that will allow me to burn blu-ray video in the future. I definitely like that idea. But, if I take 60i video into premier, edit it, then encode it as 29.97 progressive for YouTube what kind of extra encoding time would I be looking at? Twice as long as it would take to encode 30p from the camera? What does THIS video look like? Would it look better or about the same as having done the same process with PF30 shot on the camera itself.
    I'm sure many of you have already figured out the best frame rate (60i or PF30) on Canon camcorders when it comes to working in Premiere. If you have any advice please let me know.

    I don't like the idea of locking myself out of future Blu-ray authoring (or needing a conversion to make it work).  If it were me, I'd stick to shooting HD at Blu-ray legal specs.  At 1080, that means 24p or 30i only.

  • Long encoding times for footage captured with BMD H.264 Pro Recorder

    Hi there,
    I'm experiencing very long render times when encoding footage captured with the BMD H.264 Pro Recorder. Watching it encode (either through Premiere CS6, or AME) it looks like the encoding stops for periods of time. With other footage I can encode a 50 minute project in about 15-20 minutes, encoding with footage from the Pro Recorder is almost 1:1 in terms of project length/encode time.
    The Pro Recorder uses QuickTime for H.264 captures, so don't know if that is causing issues. Don't seem to have the same issue with other H.264 formats.
    System Info:
    Windows 8 Enterprise (RTM)
    HP Z820 with dual hexcore processors, 32GB RAM
    Quadro 2000 plus Tesla for Maximus configuration
    All latest updates have been installed (yesterday)
    MPE is enabled for project
    Also tested on a Z800 with Windows 7 and got same results
    Editing the footage is fast and playback through timeline looks great. Anyone have a suggestion?
    Thanks,
    Jeff

    QuickTime is still a 32 bit process and the 64 bit PP has to use a sort of "band-aid" to make QuickTime files work right.  It's possible that might slow things down.

  • H.264 encoding time saver

    I don't know if this has been discussed elsewhere, and I don't know if everyone reading this will go, "well duh!" but I discovered something last week that made a big difference in how long it takes my system to encode H.264 files.
    I have a lot of clients who want their videos on YouTube, which is why I create a lot of H.264 files.  Usually, in my Media Encoder H.264 settings, I select the YouTube SD preset (all my video is SD), which works very well.  But by making a simple tweak to the preset values, I cut the encoding time in better than half.  The preset has a frame rate value of 30 FPS.  Changing that value to match my video (29.97 FPS) made all the difference in the world.
    I have a 3:12 project that consists of simple cuts.  No transitions and no effects.  With the standard YouTube H.264 preset, this took 5:12 to encode.  By changing the frame rate to 29.97, the encoding only took 2:11!
    J. D.

    thanks for info !  Usually it is kinda normal that the workflow is just like you said...your project settings match the video "source" material. and the export matches the project settings ( as much as possible, as of course some things change ( size of frame ...maybe you have to go to interlaced or progressive etc) ..but generally frame rate is kept the same....
    once you get your settings good ( adjusting the default preset values ) you can then "save" that as your own new preset...customized...and then you dont have to keep changing it...you could label it MYH264-YOUTUBE-SD...or something ...

  • Adobe Media Encoder - Encoding Time Matrix?

    Does someone have an encoding time matrix comparing the encoding times for various MPEG2-DVD presets. I know it depends on the source foot and CPU speed, but I am trying to determine relative ball park estimates. I am especially interested in how the quality setting effects encoding time. Thanks in advance.

    I don't think you can create such a thing for the general populace. There are just too many variables.
    You can take a 1 minute segment and export at various settings on your computer to get such a chart, but that will apply only to you with that material.

  • ? Encoding time on Intel iMacs

    Would appreciate any feedback on encoding times on the new Intel iMacs.
    Thanks

    Well, it seems very fast to me. I'm burning a DVD right now, and a one-slide menu is taking it only about 2.5 minutes to complete. On my Powerbook G4, it seemed to take forever.
    I have a one-minute iMovie project I'm burning to DVD and it encoded that one-minute file in about 1.5 minutes, so this gives you an idea it is very fast. No more waiting!

  • How to capture to minimize encoding time?

    I'm capturing video from some old family VHS tapes before all of our VCRs die. I'd like to put the captured video on a playable DVD. My first one has been encoding for about 24 hours, which seems longer than it ought to be.
    The video is coming in from a Canopus ADVC-100 converter box over FireWire into the Mac. I've been using QT Pro to capture.
    Are there any capture settings or other methods that would give a significant reduction in iDVD encoding time?
    Thanks in advance!

    You must be a very patient person...... But why not do what i did? .... since I had over fifty Mini DV, VHS, and SVHS T120 tapes to quickly burn to DVD-R. I bought one of these:
    DVD Recorder with Digital inputs
    Went to Fry's Electronics here in San Marcos, CA and purchased a Daewoo DVR07 DVD-Player / Recorder (I think I paid under $80 after rebates) with FW inputs and connected the minidv camcorder directly to the recorder or VCR which then records in real time. No long waiting for encoding to take place. Does it on the fly complete with Menu, interval chapters, etc. which you set with the remote and it even records in sessions as opposed to write at once.
    It's much faster and it actually looks pretty good (but it does not have all the fancy menus and higher quality / pro settings you'll find in iDvd'08).

  • Varying (lenghty) encoding times :(

    Hello
    I have a question which has been annoying me for some time.
    When I encode a given project in DVD Studio Pro (first choosing "build" then "format") I've experienced varying encoding times, from a couple of hours to 7 or even 9 hours for the exact same project and also using the same computer.
    It is definately not fun for me, as a film student to sit at my school for an entire night, not knowing if my project will be finished in another hour or 4. And now I have experienced this on 3 projects altogether.
    The DVD SP project consists of rougly 80 minuts material, in 10 tracks (subtitled in FCP and not plus chapters), and having 2 simple menu pages. the project fill ca. 4,4 GB in total.
    On another note; I've noticed that the size of the FCP Quicktime files varies greatly in size, depending on if I choose "DV Pal Anamorphic" or "last setting" (or something) in the export to Quicktime window. Why is that so? Is theother setting a default setting or the previous setting which mysteriously compresses the files more??
    On the computerscreen or a small television, I cannot see a difference in quality... And obviously a DVD SP project which has a smaller total size, takes shorter time to encode.
    ANY help will be appreciated, it would be really great to know a way to keep the encoding times down to 3 hours or so
    Kind Regards!
    Natasha

    If you are using DVD SP to build and encode the times can vary depedning on how you set the rates for the project to encode (if you changed them) whether some of the assets are already encoded (in other words there is background encoding going on or just on the build) and whether you have built the DVD before so some of the encoding for some of the sections may be done. Also where you have exported the movie to (internal drive, a seperate drive etc.) can also change the speed.
    As an aside you are best off encoding outside of DVD SP and make the audio AC3. You can set up Compressor and get alot better idea of how long it takes to encode, and make sure the assets being encoded are not on the system drive and the target for encoding is also on another drive. Again depending on the settings in Compressor it can take a long time, especially with frame controls, but using some of the presets and/or not using the frame controls and it can be fast.

  • Premiere Pro CS3 to Encore encoding time.

    Hi everyone, I have a move timeline, and its about 1h 30m long, and I'm just trying to burn it to disc to play in my DvD player. Currently it is an AVI file. I understand that to do this with Adobe, i have imported the AVI file to my timeline in Premiere Pro and then I must export to Encore, direct to disk, no menus. I've got all this working however the encoding time is enormous, 30+ hours, for such a simple movie should not be right, I was wondering if there are other faster options? Im running a 2.66 Ghz 1.5 gb Ram windows xp computer.

    > Currently it is an AVI file.
    Why not put the AVI straight into Encore, bypassing Premiere altogether?
    For 1h 30min a long encoding time is normal, your CPU is not the greatest which is why it takes long to encode.
    Encoding is CPU intensive. Premiere CS3 takes advantage of more cores, trust me it works.

  • Rough percentage increase of encoding times of 1080p versus 720p..?

    Does this also apply to downconverting from 1080p to 720p or is that a bit less than a 1080p to 1080p conversion?
    My main question is.... what's the rough time percentage difference of 1080p to 1080p versus 720p to 720p in terms of encoding time?
    Assuming the same settings.

    About the same percentage as a lap on the Hockenheim Ring with a Formula 1 and a GP2 car. So, plus or minus 200%. Choose what you like.
    BTW, what do you think about the American politics, and if yes, why not?

  • New iMac movie encoding times?

    Thinking about getting a new 20" iMac, but am wondering what is the typical encoding time for a movie using iDVD 6? Right now I'm using iDVD 4 and a PM dual 1ghz G4, and encoding takes about 4-6 hours for a one hour movie.
    Hopefully this is much faster on a Core 2 Duo iMac, or should I consider a low end Mac Pro (or wait and decide on Tuesday, 9/12?)
    TIA

    Very interesting results, thanks for that. So, I imagine a 20" 2.16ghz iMac might be about 4-5% faster than the 17" 2.0 iMac. This looks like the 20" iMac is 10% slower than a Mac Pro but costs albut 60% less!
    I was leaning towards a Mac Pro, as I thought it was overkill for my needs, and these results seem to validate that thinking to some degree. The only downside to the iMac is this will probably be the last upgrade to this motherboard, as the next will be Conroe or some variant which is not drop in like Merom.
    Hopefully a 'mini tower' will come soon and I can get the best of both, price and power. If not, then I've got to decide iMac or Mac Pro.

  • Will encode in bundle increase the encoding time ?

    Hi there,
    I have this project which is 18 minutes long and encode in Apple 1080p 1920 x 1080 25fps, computer mp4 file.
    Since I have this phobia of having Error -50 pops up at me, I decided to encode them in 8 parts and re-essemble the 8 parts and encode the 8 parts into 1 file.
    QUESTION 1:
    Why does 10.0.6 took so long to encode ? about 2.5 hours.
    A similar 18 minutes file only took me under an hour to encode (ie encode at firts go without encoding in parts) to encode in 10.0.4.
    But, in 10.0.6, even with already one round of encoding into 8 parts, why is it taking such a long time ?
    QUESTION 2:
    Another question is if I do a bundle encode to include the same Apple 1080p plus vimeo plus facebook, will the encoding time remains at 2.5 hours or will it increase due to more destinations ?
    Thanks

    I don't understand this – splitting it into 8 parts, etc. If you're getting an Error-50, you  may have problematic media. What are your original clips?
    Q1) Unless you have an extremely complex project with loads of composited clips, effects and graphics, it's a pretty long export time.  Maybe it has something to do with the eight parts?
    Q2)  To make different versions requires more time.

  • Excess iMovie encoding time

    With my recent iMovie Project located on my 300GB firewire Seagate external drive it took over 9 hours to encode a 37 minute DVD to get ready for burning. This seems excessive. Does using an external disk drive for iMovie Projects slow down encoding? Using the internal hard disk with the same machine it took over 6 hours to encode a28 minute iMovie.Does anyone have any comments or advice?
    Thanks, Bill macatoo

    Macatoo,
    The speed of your iMac's processor is the real determining factor for encoding speed and not the fact that the project resides on an external drive.
    The encoding times you are experiencing may quite possibly be normal.
    I assume you are using iDVD so you might also try posting in the iDVD discussion area.

  • Encode time log?

    Hi all:
    I am doing some benchmarking with Premiere Pro CS 5.5 and need to keep track of the encode times. Is there a place to look for a log, or some other option that will tell me how long the previous encode took?
    Thanks!

    Thank you both so much!
    My biggest issue is that I exporting straight from within Premiere (Export > Media) rather than adding to the queue. This will make the benchmarking I need to do a lot less tedious :-)
    Thanks again!
