At high resolution, or if I wanted to grab a frame, the H.264 looks more detailed. Which is better? That's a really tough call. The H.264 image showed artifacts in dark shadows whereas the m2v image showed nice deep smooth blacks without banding. Colors were more saturated and overall the image showed more contrast. But the m2v image (viewed in QT) had some advantages too. There is definitely more fine detail, for instance in tree leaves and fabric textures.
It was interesting: My first impression was that the H.264 image (veiwed in VLC) was superior. I compared a few frames with my m2v files encoded at the same bitrate. It didn't play well in VLC either but I was able to see images. The 434 Mb file that appeared in my Documents/Roxio Converted Items folder had a ".264" extension and wouldn't open in Quicktime. It worked! I had Toast encode to MPEG-4 at 14 and 17 avg and max bitrates. But even m2v at the higher bitrate is a big improvement. Now if I could just get this working with an encode to H.264, all would be great. Is there really NO avc (mp4, H.264) file that won't trigger a re-encode in Toast? Edited Apby WayneH Gosh I wish there was a way to do this as avc instead of m2v, as this would simulate doubling the bitrate again. That is, after all, why they invented Blu-ray. If it really gives me something "twice" as good, it'll look fantastic! I believe the red laser technology of a DVD cannot exceed ~18Mbps. and max bitrates in Toast to 14 and 17 and see if that gives a better result. So I think in reality there is little improvement here - there is a bit better detail resolution coming at the expense of something else. The file size is actually ~1% under the m2v file produced at DVD resolution. The bad news is no surprise: Toast encoded to a higher resolution but the average bitrate is still 8.0, and that's how the m2v plays in Quicktime. Woot woot! I didn't burn a disk, but I'm pretty sure it would have worked as desired. Woot! I started a burn and Toast went straight to multiplexing. When dragged back into Toast, the ac3 sound file was requested. And now, because Toast was set to "Blu-Ray video" instead of "DVD-Video" tried earlier, the m2v file is 1440x1080 (actually 1440x810 16:9). m2v file from my iMovie AIC-export file and put the m2v file into my Documents/ Roxio Converted Items folder. Set to "Blu-ray Video", Toast produced a. As I said, this is beyond something I've tried.īrilliant, that did indeed work. Presuming Toast uses the converted items folder for its temporary location when converting video your. If that's not the case you can go to the custom encoder settings window and choose MPEG 2 as the format for your HD video. First, your existing video may already meet the Blu-ray specs in which case it wouldn't need to be re-encoded. However, if you have the Blu-ray plugin and choose a Blu-ray disc project, there may be a couple ways to get what you want. This bypasses Toast's encoding and multiplexing, but it requires an Intel Mac. Do I need to compromise on video quality in order to perform this trick to get DD 5.1? I've read that some folks have been able to use tsMuxeR to put ac3 audio together with HD video into a m2ts stream. (Most people might guess it was - it's very good.) I've been trying to use Compressor 2.3.1 to create an HD m2v file. It looks way better than anything I ever did with my SD camcorder, which was pretty good, but it's not HD. I just now followed your procedure and it works! I've got a cool 5.1 surround track with my video.īUT, that m2v file is only DVD SD quality. I was struggling with getting an m2v that would work without triggering re-encoding in Toast, and I never dreamed of using Toast itself to create it. Thanks a ton for this detailed procedure. Prepare the menu the way you want and burn your DVD with 5.1 audio. ac3 file extracted using QuickTime 7 Pro.
Toast should ask you for a matching audio file. Now remove the h.264 video from the Toast Video window and add the. m2v file outside of the Converted Items folder. Instead, go to the Roxio Converted Items folder in your Documents folder. This is done by adding your h.264 video to Toast's Video window with DVD Video as the setting and choosing Save as Disc Image.
I'm pretty sure this can be done using QuickTime 7 Pro. One step is to remove the 5.1 audio track from the h.264 video so it is a standalone. In order to keep the 5.1 Dolby track you need to do several steps. The reason you are getting no audio is I suspect you do not have the perian codec installed.
What it will do is re-encode the 5.1 track to 2.0. Toast won't retain a 5.1 Dolby audio track when it is required to re-encode the video. Another current topic is discussing this as well.
