I guess x264 is ok, these days ? (decodable by Quicktime or WMP browser plugin ?) With all these codecs I'd also be interested, what is the best to find being supported on the web-browsers. I asked on Usenet several times but got no reply. )Īlso it is pretty difficult to get information on encoding for Webcasts. But it may be even better if some Pro does it right. What I have found to be quite ok for Webcasts is a little profile I did with PSP9Video. Of course I can do this myself, but I know zero-nada-nothing about all the things behind the scenes and have zero experience. * and maybe something, that is best choice for later encoding into Flash Video (FLV) * Screencast (like Webcast, may be similare to Cartoon/Anime ?) * Webcast (very low size with maximum quality, only a face, moving sparingly, but needs details in the face, audio can be as low as 11KHz/8bit mono) What I would like to see is a profile for different publishing tasks, like and would anyone give me pros and cons for it since I only see references to ABR in all the guides/posts? So I guess my actual question should have been 'Does anyone use the Constant Quality setting in MeGUI?' (especially for iPod Encoding). I saw a couple of references to using -2pass to 'optimize' the file size, so I thought I'd try it since the documentation says that 1-pass encouding can have 'unpredictable' results on file sizes. I haven't seen any threads talking about using the Constant Quality setting, which is what I want, not a constant bitrate/filesize. All the guides referece ABR and setting a desired bitrate as you described above. obviously before encoding.Īctually, I did read the guide (Berrinam's) and 2 others specific to iPod encoding, so maybe I'm just not understanding things correctly. I think you didnt read the megui guide.įirst of all you need to use the bitrate calculator (to set your desired filesize) or manually configure the profile to set your desired bitrate. Isn't it possible to speed up the first pass? Kinda like the turbo option in xvid? I know it's written somewhere what options are safe to be dropped during the first pass. Very important!!! DO NOT USE -thread 2 (or more) because PSP somehow doesn't want to open movies after this. You can also use -analyse all and -bframes 5 :) X264.exe "c:\video.avs" -pass 2 -bitrate 384 -stats ".stats" -level 2.1 -ref 2 -mixed-refs -no-fast-pskip -bframes 5 -b-rdo -bime -weightb -direct auto -subme 6 -trellis 1 -analyse all -me umh -thread-input -progress -no-psnr -output "c:\video.mp4" "c:\video.avs"Īs you can see -level 2.1 is required. X264.exe "c:\video.avs" -pass 1 -bitrate 384 -stats ".stats" -level 2.1 -ref 2 -mixed-refs -no-fast-pskip -bframes 5 -b-rdo -bime -weightb -direct auto -subme 6 -trellis 1 -analyse all -me umh -thread-input -progress -no-psnr -output "c:\video.mp4" "c:\video.avs" PSP profile requires update!!! Below settings which work on my PSP 3.02. If you're testing with a 60 second file or something you'll probably get a working file without NiceFPS but when you move onto a full size (30min, 1 hr, etc) you might run into problems, NiceFPS shouldn't slow things down and is a nice backup just in case so you don't waste encoding twice to get it working. bit rate up to 1500kbps (as far as I know, I have gone as high as 1200 and as low as 800) and I can say that auto two pass and auto three pass work.Įdit: Might I add that I also need to use NiceFPS AviSynth plugin with these files to get them to work in Quicktime or iTunes. Once you get the hang of working with files using those settings you can change the avg. Mux these two files using NicMP4Box v1.0, it has a hack which will let you make 640 pixel files that work on the iPod. For audio you need to downmix to two channels and make sure it's constant bit rate 160kbps or less (I use 128kbit so try using that first) and ACC-LC setting. I have encoded iPod videos using MeGUI with Shark's 5.5G profile output set to mp4. Using Sharks 5.5G profile without changing ANYTHING should work fine.
