> What does your script do in MPEGStreamclip, besides the export? I noticed that it does some sort of cropping. I was just curious about that. It it because, occasionally, videos from the replay have that little static line at the top of the screen?
Firstly, I picked MPEG Streamclip because it was the only application that didn't drop the audio when transcoding (i.e. converting muxed-MPEG2 to H.264). FFMpegX, VLC, and QuickTime dropped the audio, as did every other application I could find. I wanted to make ReplayToGo independent of needing the MPEG-2 Playback Component, but only MPEG Streamclip would work and that requires the MPEG-2 plugin.
On my Replay (45xx), the video was surrounded by a black frame on three sides. Since I wanted to have as much as the content as possible, cropped off the black pixels on each side. This can be adjusted however if it is different with different Replay generations. Simply open /Applications/AppleScript/Script Editor, then open the ReplayToGo.app file (it is a simple AppleScript).
> How about an option to use MPEG4 at a higher resolution. I don't mind sacrificing size for quality. Something like 544x408 would be within the 480x480 max resolution for MPEG4, but show up much better on a TV than the 320x240 h.264 file.
I tried this (and FYI the max resolution for a 4:3 aspect ratio is 512x384 while maintaining the 'must be divisible by 16' MPEG-4 rule) and I found that the quality of H.264 at 320x240 at 700 kbps is better than MPEG-4 at 512x384 at 1325 kbps. The MPEG-4 just seemed to smear and pixelate more than H.264.
I hope that eventually, the iPod will decode a higher resolution of H.264.
That being said, it is possible to change the ReplayToGo script to MPEG-4 and a higher resolution, if desired. This is my first attempt at GUI scripting (since MPEG Streamclip isn't scriptable) so it may or may not be easy to do this.
> To me, the current weak spot of the video iPod is the low resolution when plugged into a TV.
I completely agree! Come on Apple, give us an iPod worthy of "This (2005) is the year of Hi-Def".
> I realize that part of this limitation is dictated to the currently small drive sizes available (30 and 60 gb currently).
The current generation of iPods are limited by it's video-decryption chipset. (AFAIK)
> Well, using MPEG4, you can get 480x480 and if you are ripping something that is in widescreen format, that means that you don't have to reduce the size. The following resolutions will fit on your iPod and look great on your TV.
ReplayToGo is designed to move videos from a ReplayTV to and iPod. Since most of the content that comes off the Replay is in a 4:3 aspect ratio, I won't be changing it for widescreen content. It just wouldn't make sense.
I want to encourage everyone to open this script up and modify it for your own needs, however. It is only an AppleScript which anyone should be able to read and modify if you want to. It has a couple of really useful sub-routines that can be changed for use in all kinds of different scripts.
