TUTORIAL: From miniDV to Vimeo in High Quality on Vimeo . best 4Moorhens2 Eugenia-- Introduction --It seems that a number of Vimeo users are confused about aspect ratios and how to eliminate jaggies, so I put together this tutorial for you. With this guide, you will be able to export a clip from any miniDV camera in DVD high quality, that will get the HD treatment here on Vimeo, without your footage having to be HD. Here's a sample of the quality you will get from your miniDV PAL/NTSC non-HD camera if you export the right way for Vimeo: vimeo.com/411905Please note however, that this high quality re-encoding for non-HD footage feature might disappear from Vimeo in the future (your existing videos should be unaffected if that's the case though). baixar dvd shrink em portugues gratis. Regardless, that's the correct way of exporting widescreen miniDV footage for the web/devices in full quality, so it's good to know anyway.-- Method --1. Make sure you set up your camera to shoot in widescreen. The high quality re-encoding at Vimeo is only possible for widescreen miniDV footage.2. Import your footage to your PC with the video editor of your choice. You can now choose to either edit the footage, or just use a single unedited scene in which case go to step #3. If you choose to edit the footage first, make sure you export from your video editor in .avi DV widescreen interlaced mode, so quality loss remains minimal. Most video editors support exporting back to the same DV codec, and if not, use another intermediate lossless codec to export. Do not export in a lossy codec, make sure it's DV AVI or an intermediate lossless one (e.g. Huffyuv).3. Download and install the freeware open source Handbrake utility: handbrake.fr/?article=download4. Then, load your file to convert on Handbrake, and make everything look like this: eugenia.gnomefiles.org/images/handbrake.png (use 872x480 resolution, 2500 kbps bitrate, the rest as in the screenshot)4a. *IF* your camera is a PAL 16:9 camera, you can try exporting in 1280x720 at around 5000 kbps bitrate instead of the 872x480, 2500kbps suggestions above. But that's only if you shot in widescreen PAL. Resizing to 720p an NTSC widescreen or a PAL/NTSC 4:3 signal is not a good idea.5. That's it, after a while (depending on the speed of your PC), you will have an .mp4 file, ready to be uploaded to Vimeo. When it's up, it should have the HD treatment and look all fabulous.-- Some important notes --* This kind of export will create DVD-quality files that are playable as-is on the XBoX360 and Sony PS3! It should be playable on the AppleTV too, but I don't have one to test.* If you are proficient in using your video editor's exporting dialogs with similar settings we used here, then there's no reason to use Handbrake. However, most people can't do that, which why I wrote this tutorial, using a single utility for all cases. If you feel adventurous though, or if you are using a Mac, you can follow my other, HD, tutorials here vimeo.com/forums/topic:3671 and follow them exactly, except for 2-3 changes you will have to make to reflect your non-HD source footage: 872x480 size instead of 1280x720, 2.5 mbps instead of 5mbps of bitrate, and the right frame rate each time (29.97 for NTSC, 25 for PAL).* I suggested the same exporting resolution (872x480) for both PAL and NTSC miniDV footage. In reality, widescreen PAL can go up to 1048x576, but that's quite some over-stretching over the original 720x576 recorded frame size and so a resize down to 872x480 can be beneficial in terms of quality.* For those who are confused why we don't export at 720x480 (NTSC) or 720x576 (PAL), it's because in order to get widescreen in these resolutions, you have to set the 16:9 flag in the internal format of these videos. Problem is, Vimeo and many other players usually don't respect these flags, and so your videos come out as 4:3. In order to go around this limitation, we export in aspect ratio 1.0000 (instead of 1.2121 for NTSC and 1.4568 for PAL), and so the 872x480 resolution is based on that aspect ratio. It's ok if you don't understand what I am talking about here, just trust the results.* If you do not own a widescreen DV camera, in order to export with the right 4:3 aspect ratio you need to do the following: export at 768x576 for PAL, or at 656x480 for NTSC (at around 2000 mbps instead of 2500 shown in the Handbrake screenshot). You won't get the HD treatment at these 4:3 resolutions, but these are the right aspect ratio 1.000 resolutions you should be exporting for web usage from 4:3 miniDV.Eugenia, I've tried using Super to convert HD .flv files to .avi which it does very well, however with it installed on my pc (windows xp sp2) it causes Windows Media Player 11 to freeze and crash when I try to play mpeg-2 files - mpeg-1, .avi, wmv etc. are ok. Probably a conflict with my Cyberlink Video/SP Decoder?I have installed/uninstalled Super twice and still the same problem with WMA, any ideas? No problems with Cyberlink PowerDVD when Super is installed - strange!Also thanks for your above advice about rendering video files for the vimeo HD reatment for PAL 720x576 (16:9) mpeg-2's I use VirtualDubMod to resize to 880x480 and the Xvid 1.1.0 codec to compress to 3000 kbps together with Lame mp3. I have uploaded to vimeo a .avi test video, using these settings, and it looked good in .flvAll the best, 4Moorhens2.Eugenia,I'm still having problems with SUPER and WMP, i.e. playback of mpeg-2 files on WMP with Super installed, maybe the latest version of SUPER (Feb 5 2008) has a few bugs - could you possibly link me to an earlier version?Its not a big deal, because I prefer VirtualDubMod, but Super can convert HD .flv files to other formats and that is very useful - VirtualDubMod doesn't support them and Prism, which converts non-HD .flv's, always says no thanks! after converting the first few megabytes of a HD .flv.All the best, 4Moorhens2.Hi Eugenia, thanks for the reply.How do you think vimeo could improve the conversion to 24 fps .flv?With VirtualDubMod - e.g. mpeg-2 25 fps to Xvid 24 fps conversions - if one uses Source Rate Adjustment then there are noticable dropped frames, but with Frame Rate Conversion subject movement is much smoother although keeping audio in sync can be a problem.Is it a similar thing with your Flash converters, i.e. the choice of dropped frames or out of sync audio?Also, in the past, I have downloaded 25 fps .flv's from other sites - perhaps in the future vimeo may be able to to maintain the uploaded video's frame rate: be it 25 29.97 30 etc.....Cheers, 4Moorhens2Hello Eugenia, I was wondering if you could help me out.I uploaded a movie exported from Adobe Premiere baixar dvd shrink em portugues gratis. Since it is a 16:9 instead of widing resolution I decided to lower height in order to have square pixel with smaller file size.The problem is that I export video in 720x405 and Vimeo turns it to 720x406 which will put a black line at the bottom. If I try to export video from Premiere with that settings Premiere will put black lines. My 720x405 is clean...Why is vimeo messing my dimensions? thanks!vimeo.com/719586The black bars will have to be vertical AND horizontal. And this makes up for a quite ugly picture IMO. You will have to export at 1280x720, with black bars left and right and up and down, and in the middle have a 1:1 video resolution depending on how you shot:PAL 4:3 is 768x576 (it is not 720x576 after you make the aspect ratio 1.000)PAL 16:9 is 1048x576NTSC 4:3 is 656x480 (it is not 720x480 after you make the aspect ratio 1.000)NTSC 16:9 is 874x480I do not recommend resizing a miniDV resolution to bigger than its native resolution because this has a toll on the quality.Just tried out your suggestions at home: resized to 1280x720 (Lancros3) and compressed to 4000 kbps Xvid with VirtualDubMod plus Lame mp3 48 kHz 128 kbps, 26 MB total, duration 54 seconds.The result shows no noticable loss of quality over the orginal, but video files at that spec would be very large for uploading - maybe around 30 MB per minute of footage.I wont upload anything like that just now, perhaps we can wait for any developments on the 1048x576, 720x576 or 720x480 DVD quality HD request... a slide show video using JPEG's at a low bit rate, of say 1000 kbps, at 1280x720 still seems to be a possibility...Eugenia, I've just downloaded the latest version of SUPER v2008.build.32(Jul.8,2008) which has some additional AAC features that were not available in the March 2008 version that I was previously using: provision for 6 channel audio and various new AAC settings from the ...Output Audio Codec drop-down menu - I have found that AAC LC (low complexity) works well at 44100 Hz, 128 kbps, 2 Channels.It will still not deinterlace mpeg-2's, in fact it appears to struggle slightly to encode them to H.264 on my machine, but it handles an imported progressive or deinterlaced mpeg-2 just fine.Thanks for your continued and valuable advice, 4Moorhens2.HI Eugenia. (excuse my lenguage)Your tutorials are incredibles! Awesome!I´m from Argentina, and now i´m encoding from DVpal to HD with the program you recomend: SUPER. Excelent!Now i want to know if with SUPER can i encode an HDV video (1080 x 1440, 50i, of Sony Z1) to HD for vimeo. And how?Because i´ve Windows, so with PREMIERE it make me a TOO HEAVY video (i read you tutorial for this.)I think this program SUPER is better and easyer for encode than Premiere media encoder.Can you help me to do this with the SUPER?Thanks a lot! You are great!Ok, thank you for the answer. So it really depends on situation?For example if I export from Premiere in 720x576 with 1.4333 (pure 16x9) it means that I should use 848x480 or 1024x576.(of course if the input to Premiere was in pure 16:9)Same for encoding from PAL DVD.Capturing from HV20 will also lead to real 16x9 (1280x720) so it should be treated as 848x480?In other words one should keep an eye on the source of footage to choose right resolution for square pixels rather than on settings of NLE?People with deinterlacing issues. Just feed the source first through avisynth.install:free-codecs.com/download/AviSynth.htmfree-codecs.com/download/Helix_YUV_Codecs.htmdownload these plugins:neuron2.net/decomb/decombnewavisynth.org.ru/yadif/yadifUse this script:#Loadplugin(decomb.dll)Loadcplugin(yadif.dll)avifilesource(your.avi,pixel_type=YV12,fourcc=dvsd)#Fielddeinterlace(blend=false)Yadif(mode=1)for some sources i prefer fielddeinterlace (= decomb filter) but for most others yadif. Make sure to fix the correct path, watch the C in loadCplugin for yadif, note the # which disables the code, and copy/paste this in an nameyour.avs file.If you do everything right you can open this in super or any other encoder and encode your footage as a nice progressive file. I have been doing this for years and started doing with super when i found out the build in deinterlacer does not work.Hello Eugenia, I've read extensively through this thread and also through this one: vimeo.com/forums/topic:3671 but still can't find a solution.I have a vid of the following settings: DVCPRO50 - PAL, 720 x 576 (1024 x 576).I've exported various versions, with a bitrate varying from 3000 to 5000 kbps, yet the quality turns out to be really poor on Vimeo.My latest compression attempt was: H.264, 1048 x 576, 5384.82 kbits/s. I followed your suggestion above to export these dimensions.Could you let me know if I'm missing anything?thank youHi Eugenia, I found this sticky thread like you suggested.Sorry for not being able to unravel this myself.In the final paragraph of your tutorial above, I see you say if one shoots without a widescreen DV camera, (like mine which is a DVX100B), then I need to export at 656 x 480 in order to achieve a 4:3 aspect ratio.I tried this and uploaded to Vimeo as a second test, but I can't see any difference between the one I originally exported at 640 x 480 and this second test.In both cases, the image is squashed vertically. Shouldn't the horizontal number be less than 640 so the image will grow vertically?By the by, I'm using Adobe Premiere Elements.Tanks!
