[videoblogging] Re: DV to iPod (320x240) dilemna
Its a sad joke that Apple still havent fixed this ( I was hoping QT7.0.4 fixed it but just tried and no, still doesnt take account of rectangular pixels). When this problem was first discussed here, I got it as wrong as Apple (mind mess over rectangualr pixels), but its inexcusable that they havent sorted it out yet, all these years I heard how Apple were better for video and then they make a mistake like this. Regarding why your workarounds havent worked: When you tried going to 640x480 first, you then tried exporting the 640x480 version using the 'export to ipod (320x240)'? And this fixed the 320x213 issue but the video quality wasnt as good? Strange, as I wouldnt have expected pre-reducing to 640x480 to affect the quality of the final m4v file, unles the 640x480 resizing hasnt been done properly (eg interlacing issues) or Apple ahve something strange going on with the ipod export resize filters. As far as what the nearest manual settings are for achieving the same as apples ipod export option, its possible apple have done some special tweaks to that mode, but its possible to get nearly the same manually: Export to mpeg4 Video type: H264 bitrate: about 700kbits/sec frame rate same as source Key frame: dunno, experiment press 'video options' button: Untick Main, tick Baseline Choose Best quality or Faster Encode (see below)* Audio: AAC-LC (Music) 128 kbps rest of audio settings probably dont matter much *Apple made some ipod export changes with qt7.0.4 compared to 7.0.3. Based on encoding times, I believe QT7.0.3 ipod export used multi-pass mode (so better quality) but Apple were getting stick for how slow the export was, so in QT7.0.4 theyve changed it to Single-Pass to stop encoding times being too depressing. Take your pick. Hoe that helps a little, if you are on a Mac then consider trying alternative encoders like iSquint to see if you prefer the quality, if you are on Windows there are other options too.

Re: [videoblogging] Re: DV to iPod (320x240) dilemna
I've tried this one a number of times, but it just does not compare in sharpness, and size to the auto export to iPod (320x240). But this may all be mute, if in fact that 7.0.4 does not do a multi-pass. I have not tried it yet, but I have a sneaky feeling that the quality will drop with the single pass. Which means getting back to 7.0.3 somehow. Thanks Steve, you always come through... Chris ps I have yet to try iSquint, or Divx for that matter.

you cant do multi pass with the videora converter.
