WMV is not lossless. As all distribution formats, it's highly compressed. An AVI file can of course be uncompressed, but on the Mac version of AE, AVI is only available as a Quicktime export component (ie, it appears in File > Export) which is really not a recommended path to export video files from After Effects. Same for Flip4Mac. So, yes, exporting a ...

VLC is usually quite slow to update their version of ffmpeg. A recent build of mpv should do well. It's been playing h.265 for me since well before this question was asked. Also note that Adam's answer is not quite right. x265 is an encoder, and doesn't include a decoder. FFMpeg's hevc decoder (in libavcodec, aka lavc) is the main Free Software ...

Upscaling at playback time is done by graphics hardware, not the CPU, so your assumption turns out to be false. Good software players will feed the video through high-quality hardware scaling (e.g. mpv's opengl-hq video-out). HW upscaling might still default to bilinear, though, so it's worth thinking about this. Upscaling before encode spreads the detail ...

This depends on how much resources you are willing to invest into upscaling content. The default setting for libswscale in VLC seems to be bicubic, if you intend to use more sophisticated resizing filters and a particular target resolution then you should upscale the video during encode this way you also don't have to rely on the capabilities and customizing ...

I think MeGUI is supposed to be a good front-end for x264 encoding. (x264 is the same h.264 encoder that VLC uses.) I don't know anything about powerdirector, so all I can say is that x264 is the best h.264 encoder (best quality vs. bitrate vs. cpu time tradeoff), and it's free. It's what you should use to make files for upload to youtube. (Use lots of ...

AVCHD appears to just be h.264 with some constraints. Mainly on framerate and resolution. It looks from the wikipedia page that early versions mostly favoured interlaced encoding, unless you drop down to 720p. The wiki page doesn't say, but I assume it's H.264 4:2:0 8-bit, not Hi10 profile or something. I also have no idea what quality the hardware ...

Yes, some encoders allow changing parameters (like target quality or bitrate, or psychovisual tuning options (x264's aq and psy-rd options). x264, the stand-alone command-line frontend for the library, has a --zones parameter to give more bitrate to some parts of the video. So you could for example reduce the quality for the credits. The actual x264 ...

You focus on quality in your question, so the answer is clear: ProRes (in various flavors) offers superior quality. There are other reasons you might choose AVCHD, but they don't relate to quality. AVCHD is generally speaking a distribution format, while ProRes is more an acquisition and intermediate format (it uses all I-frames). ProRes also comes in a ...
