1280x720 MPEG4 Problem

[fmharr]

I have been trying the new Showsqueeze and it never completes (1280x720p).

It (1 hour 1080i show) has been running at 100% cpu for 18 hours with no errors in the log.

I have tried several other files and none of them completed either (I terminated them after 9 hours).

I did have one complete with the default (Intelligent Quality Selection = Yes) but it still took 7 hours an the quality was poor on my 1080p 52" HDTV.

Anyone having success with the 1280x720p MPEG-4 Showsqueeze???

OK, they finally finished after 27 hours.

The only errors in the log is that they failed to write the metadata at the end on both.

A check of the video folder shows that both mp4 files are zero byte files.

Also noticed that both were tryig to run at the same time. This should not happen on my single cpu/ single core system. I have now set the webui setting from auto to single core mode. (this is a new feature of this build).

I did another test

1 Reorded 6 min of the Today show in 1080i.
2. Showsquezed using 1280x720p mpeg-4.
3. It took 61 min to complete the showsqueeze job (not including smartchapters).

It did complete this time and the video was almost as good as the orignal.

But an hour for a 6 min video????? That equates to 10 hours for a 1 hour show!

Now I reliaze that my system is not the fastest (A64 2800+ 2gig) but come on!

I am updating my system to a faster cpu/mobo (maybe a dual core) , but until I do this feature is unusable on my system.

I suspect that the previous failed attempt my have had something to do with BTV failing to detect that my system is a single cpu/core.

Also of note that playing back the mpeg-4 video sucked so much cpu power that any remote or keyboard events took upto 30 seconds or more to take effect. Video was still smooth. I tested with both Snapstream decoder and nVidia decoder and there was no differance.

Your system just isn't fast enough for 720p H.264.

what speed/configuration is good for 1080i rez H.264. encode/decode

can't record it yet but i will want to in the future if possible.

the fastest system i have is a 2.9 ghz(thinking of using my 1.9ghz system as a link machine.)

What are the system requirements for 720? Also, as Jkirk asks, what is the system requirements for 1080?

Also, does H.264 keep AC3? If not, it would be nice Divx or H.264 or both have the option to keep AC3. Not have'n 5.1 for HD just don't do it.

Doing compression is already CPU intensive, but once you add rescalling, no wonder it takes 10 times longer than the file's duration... You should try a test from a show on Fox or such, to have some material already in 1280x720p...

Are any of the settings able to retain the original resolution and audio, only compressing the video? There was the option about retaining the 1:1 pixel mapping, but that could be something else, to match the display's resolution?

[fmharr]

I guess it is time to upgrade my mobo/cpu/video.

I was going to upgrade to a 3700 or 4000 A64 but I thing even that will not be good enough.

I will have to look into a core 2 intel board.

OK,

I have acquired the following:

ABIT AN8-32X
A64 X2 4800+
2 gig PC3200 memory
PNY 7300GT 256mem PCI Express

Does this have the power for 720p H.264 ???

It would be great if there were a built in encoding/showsqueeze option that would keep the audio for HD shows (DD) and also keep good detail and compression.

To answer my own question: Yes

The showsqueeze that was taking 24+ hours now takes less than 5 hours and playback of MPEG-4 videos is now very smooth.

The only drawback with this system is I had to give up one of my PVR-150's because The motherboard only has 2 PCI slots. But since I added the HDHomerun, I don't need the 150 anyway.

I know this is not built in, but consider the AutoXvid plug-in. It can be configured to keep HD audio and the resolution of the video can be set.

hmm no response yet.

the world may never know the minimum specs.

Don't know, but mine (dual core A64 4800+) does not break a swet with 1440x1080 or 1280x720p.

that is nice to know.
