In a bit of bad timing for the passing of Aperture, I've used it to create a 17-minute slide show for a wedding rehearsal dinner. Then I exported it as a 1080p HD movie that I can play at the dinner, creating a roughly 7 GB .mov file. Since I aim to use a video projector during the dinner, it will be blown up pretty large so Im definitely looking for the best HD quality I can achieve. I live almost 1,000 miles from where Ill need to connect to a projector, so my goal is actually to arrive with multiple options for playback, since I know from experience I cant count on any particular one to work. One of my options is to use Toast to burn the movie as a 1080p HD video to a DVD (not a Blu-ray disc since I dont have a Blu-ray burner). When I do this, however, Toast displays the DVD size as around 2 GB. I am able to play this in my Blu-ray player and get 1080p playback on my TV. It's definitely watchable, although the colors suffer a bit. My question is: Why is the output file so much smaller than the 1080p file exported by Aperture? Is this something I should worry about? Let me elaborate a bit. First, Im using Toasts High-Def/Blu-ray Disc Plug-in, with which, according to Roxio, you can burn high-def video content on standard DVD discs and play them back on your set-top Blu-ray Disc player! When I start Toast, I have the video tab selected, the format set to Blu-ray video, the media set to Blu-ray disc, and the quality set to best. When I drag my 17-minute, 7 GB movie file onto the Toast Window Toast shows me that it will consume 3 GB of the 23.3 GB available on a Blu-ray disc. If I keep everything the same, initiate the burn, and insert a DVD-R, the size changes to just under 2 GB (plenty of room to spare), and the burn is successful. When I insert the disc into my Blu-ray player, it appears as a DVD-R AVCHD disc and plays as 1080/60p MPEG ranging from 14 or so to 17 Mbps. As far as I can tell, Im getting full HD, however, even when Toast thinks everything will be Blu-ray, the size drops from 7 GB to 3 GB, which concerns me, and then once Toast realizes Im actually using DVD media, the size drops by yet another GB. My challenge may be to reduce the amount of compression to achieve better color resolution, but maybe a DVD has an upper limit on the Mbps it can deliver. An additional approach is via HDMI from an iPad, using Apple's HDMI adaptor. This is an appealing approach, since I have an iPad Air from early 2014. One question is the quality. Amazons reviews contain a lot of complaints about the loss of quality and resolution through the adaptor, although most of them seem to be using it with iPads older than mine. Another question is what is the best way to get the movie onto the iPad? iTunes sync? What app should I use to play it? Has anyone had any experience, good or bad, using this approach? Any other gotchas? So far these seem to be my alternatives: a) burn HD to DVD using AVCHD b) use an iPad and HDMI adapter c) use a flash drive (assuming the projector has a USB port and can play the format of the file it contains) d) bring a laptop and use HDMI e) get a Blu-ray burner and media and find a Blu-ray player locally Any other suggestions?
