QT 7 Public Preview

H.264 Hi-def clips

Previous H.264 benchmark thread

Odd. Just installed the QT7 preview. The h.264 files I encoded with Moonlight OneClick compressor don't playback in QT7

Anyhow, the BBC clip actually plays worse with QT7 than with the Moonlight/Elecard MPEG2 player. I got 10FPS before. But with QT7, I can only get 5FPS. CPU utilization jumped from 60% to 98% also.

OK but how do you download these clips. when I move the mouse cursor over 480/720/1080 blue boxes, nothign happens. I have a feeling none of these clips work for windows.

Did you click the boxes?

(also, Serenity 1080p has the downloadable .zip on the right)

Err... Click on the boxes. I get about 12 fps with my P4 1.6 (with PC133 RAM), with Serenity 480p.

Yeah, but Moonlight doesn't play in real time, does it? With my 12 fps on my P4 1.6, I am getting real time playback (with dropped frames).

I was getting no dropped frames on some material on my Celeron 1.4 with the Moonlight player, but not at real time speed. Talk about a strange way to play video.

Yes. Nothing happens.

Such BS! I click on these 480p, 720p, 1080p, and not a damn thing happens! I can't even right-click to open the link.

How do you know your FPS?

I was able to run multiple 720p without issue.. The Batman Begins in 1080p ran fine, couldnt tell the framerate though..

The aspect ratio is a little messed up. Steve is distorted.

For those of you who get nothing when you click 480p, 720p, etc., make sure you open QT7 at least once (i.e. go to Start->All Programs, etc.). I had the same result on my limited user account I use for surfing until I actually logged on and opened QT itself.

That works for all of the 480/720 but neither CTRL + i or Movie Info don't work with 1080i/p

Dangit, my Quicktime Pro registration will not activate QT7.

Serenity in 480p I get 24fps constant, and in 720p I get 12-24fps. I can't find the 1020p download link, which is weird because I could have sworn I saw it before.

The BBC clip is wierd on my machine too. It plays at only 12fps, but my CPU usage is 64%. What's wrong with this garbage software. The other clips fare better but also sacrifice some FPS for CPU time, but not so much. I even set it to high priority but it didn't make a difference.

Oddd.. Mine gets pegged around 98-100%

Some of the 480p clips only take 40-50% though..

Maybe the final release will help things out a bit..

QT 7 intentionally sacrifices fps for playback stability. From what I have been told, 12 fps is a LOT easier than 15 fps, not just because of the frame rate, but because of the way the files are encoded. Thus, a lot of machines would hover near the 12 fps frame rate instead of chancing 18 fps and getting a sound dropout or something.

I in fact much prefer this. On my Celeron 1.4 Tualatin with the Moonlight player, I can get some clips playing with NO dropped frames whatsoever, except that it takes 50% longer to play the video. Basically, it plays in slow motion, averaging out to 15 fps, with the sound cutting out. That is completely useless for video playback IMO. I would much rather it just play correctly at 12 fps.

I get about 10-18fps in Serenity at 1080p. I wish I had a screen to match that resolution...would be nice.

I see what you mean as there were jumps into the 70-80% range on occasion. I guess it keeps it at 12fps (exactly half of 24fps which is the full frame rate for that file) instead of trying for 15fps or 18fps and suffering from a hard drop when the CPU hits 100%.

I think that it plays better in Zoomplayer personally though. I can't measure the frame rate but it looks smoother in left to right pans. I don't what it is doing differently if there even is a real (as opposed to perceived) difference.

EDIT: I just remembered that when I set it to realtime priority, it increased the frame rate to around 18fps, but the sound would stutter once in a while.

Bump so we dont get more topics on the same thing.

Makes no difference. People don't browse other topics even it this was at the top before creating their own duplicate topic.
