If it’s 320x240 video then you might get away with medium setting. The setting High correpsonds to 768k video. Use the slider instead as this looks like it uses variable bitrate encoding (VBR), which gives better quality - I’m not 100% sure if that’s the reason but the slider gives noticeably better quality. When you do this in Quicktime, don’t set the bitrate manually though because this seems to use constant bitrate encoding (CBR). I used that on the elephants dream trailer to get it down to 7MB and it was just over a minute long and around 640x360. For dvd quality, 768kbps is the generally accepted cut off point for loss in quality with mpeg-4. Mjpeg is more an offline format and it is similar to dv as it doesn’t use inter-frame dependency so you can scrub through the movie forward and back very quickly.įor online formats, I recently prefer H264 because of the quality/file size ratio. I load a PNG image sequence directly into Quicktime and export as a Quicktime movie using either H264, mpeg-4 or Mjpeg/photo-jpeg. What you need to do is adjust the bitrate of your video. What I would say is don’t reduce the resolution of your movie. I think Quicktime is still better though as it gives you a lot of tools and info about the movie. There are free tools that let you encode so you don’t have to buy it such as QTCoffee and QTamateur, which just do a similar thing to Blender and call the free built-in Quicktime libraries. I agree that Quicktime is a very handy tool to have. Thanks again, I’ll have to go shopping I guess Is still need to be able to add the audio track then re-output so it’s gonna be QT-Pro or something. The sequencer recompiles into video in a matter of minutes so you can play with a range of format outputs working with original quality images as the starting point every time (actually, I might even try that tomorrow!). With images you just restart, render one image and there you have it. If you render direct to video (I do for tests and short anims) then if something crashes on the very last frame, you lose the whole render. The major one being that if the system or Blender crashes halfway through the three hour render (and that’s not a big render in the scheme of things), you don’t lose everything. Masterhoshi Rendering to images is actually recommended for a host of reasons for bigger animations. Does it allow any manipulation of the audio, like shifting it around for sync? Can multiple video tracks be added and can any effects be added (fade in/out, cross-fade etc)? Is the transcoder a GUI app or command line? Any link for it?īischofftep I want to read a bit more about using QT Pro though it’s looking like the best solution. I looked for VLC transcoder but all i find is VLC Player. It’s very buggy with some features (add audio) just not working. Kattkieru Yes, I’ve read so many amazing things about ffmpegx but to date I’ve found it completely useless for anything at all. Even if it was, I’d still have to post-process to add the audio and would be where I’m at now. Rocketman: As far as I know (looking at Xvid site) Xvid is not for Mac and AVI codec is not an option in Blendermac. It’s looking like QT-Pro is the most viable answer. I just want to get my Blender output combined with audio then output to an acceptable size. I really could use some pointers on producing an acceptable, sharable output of modest size on anything that will work reliably and relatively easily in OSX Panther (10.3.9). (The “simply drop a file, choose a format then press go” thing never works - ever.) The whole interface and barely explained variety of options leaves me feeling somewhat inadequate. I either get a video file with no audio track or the encoding fails for any of a host of reasons, none of which mean anything to an ignoramus like me. I have a copy of ffmpegx (OS X GUI for ffmpeg) but quite frankly, it just doesn’t work. I’ve reduced the image size to 180x320px but it’s still too big. I’ve tried a variety of compression options using Quicktime output but can’t get the file below 29Mb even on low quality (There a re more to try but it’s getting frustrating now). The inbulit AVI output option insists on a standard image ratio which might be okay except I rendered a tall thin video, not a short wide one None of the available options in HyperEngine seem to solve the filesize dilemma satisfactorily. This leaves me with a 70Mb file and this is where things get depressing (again - I knew it would happen) I took this video into HyperEngine AV to combine with the audio track and output to MOV again. I rendered to PNG files, then re-rendered to Quicktime from the Sequencer. I’ve finally produced something resembling a complete animation (a little over a minute) and despite a few weird artifacts it’s quite acceptable.
