Great blog. I really liked it. I have also created a lens in same niche. This is my first time, hope u guys like it. Here’s a brief intro: In your search for some top gambling strategies you’ve probably come across various systems, but the bottom line is - the odds are stacked in the casino’s favour. The only real system that overcomes this is card counting at blackjack, which is illegal. However things have now changed…For nearly 10 years a group of serious businessmen in a dedicated research laboratory did in depth research into highly advanced mind power techniques, including some incredible top gambling strategies. http://casinoonesite.com

I have tried to import a file with an extension of .MP4 into xpress 4.0 to convert it to mpeg2 (Gspot tells me it's a H.264/MPEG-4 AVC file) but when I import it, it's jerky and freezes about 30 seconds in. The latest version of quicktime also does this, but it plays fine in cyberlink powerdvd and convertXtodvd converts it fine. I have the latest ffdshow installed, is there a way to change what codec xpress 4.0 wants to use for this file (it wants to use quicktime, but I want to try ffdshow)

Any help will be appreciated

What is your PC spec? If your file is HD then your PC + TXP4 might not be able to keep up so it gets jerky or pauses for a long time if you jump the slider.

With that aside, how does the output MPEG-2 file look? is it normal?

You could try going into Option > Preferences > File Input > disable Quicktime file reader and MPEG file reader then enable DirectShow if you want to use external decoder.

Go to Options...Preferences...Input/output format list...File input plugin and turn off the Quicktime file reader plugin. It's buggy. Be sure that your Direct show file reader is checked. When you are in source stage and add file, you will need to open the "Files of Type" dropdown menu and click on All Files (*.*). Ffdshow will work here. You may need Haali Media splitter for the MPG4. I have Ffdshow and Haali Media splitter loaded and this works.

I don't know if 4.0 Express is coded for 4 processors. That could be the problem, but someone smarter than myself would have to answer that one. See the previous forum post that I started on getting 4.0 Express to use both of the cores on my E6750 dual core processor. Through some trial and error I was able to get 4.0 Express to use both of the cores on my dual core processor. Support for dual or quad core in 4.0 Express might be hardware or software limited depending on your motherboard and processor or what type of file input and output you are trying to do.

How much do you want TXP4 to use? 50% I think is more than enough for a Quad core, if you want it to use 100% then that may fry your chip in a couple hours of continuous usage. A majority of software are optimized and sometimes managed by windows not to use 100%.

nTekka - That has to be the stupidest comment that I've ever seen and is 100% completely untrue. Running your CPU at 100% utilization does NOT (and never has) decreased the lifetime.

Next time, please don't answer questions that you're not qualified to answer.

I have the same problem with my quad cpu Opteron system. I can't ever get more than 50 to 60% CPU utilization accross 4 single core cpus. I've tried setting priority to high for the process and eliminating page file usage and its the same. I've installed all the cpu and chipset updates from AMD as well. Maybe TMPGENC is just not optimized for multicpu systems?

For some reason I thought that 4.0 Express could utilize both cores of a dual core CPU system while encoding. I'm encoding VOB files to MP4 and it only uses one core of the CPU. I have all of the usual SSE and Core2Duo / Extreme options checked under CPU options. I'm just wondering if 4.0 Express is written to use both cores or not.

Changing the virtual memory size for Windows to zero seems to have unlocked 4.0 Express to use some of the second core on my processor. Encodes are going about %30 faster now and 4.0 Express is consistently using all of my first processor and half of my second processor. Interesting. Swapping data between RAM and virtual memory on the hard drive must have been hamstringing 4.0 Express for some reason. FYI: I have 3 GB of RAM in my system.

Thx for the info, I wonder if this only affects MP4 output? I have had similar issue with WMV output where only 1 core was being utilize. I will try your method and hope it boosts my performance. 4 GB Dual channel RAM on my Win XP.

For some reason 4.0 Express doesn't always utilize both cores when I start the encode. If this happens I then save the project file, close the program, open it back up and restart the encode and it usually uses both cores. Weird. I think that every time I have had it use both cores I have had the project file saved before I encode. But it is so much faster and worth a few seconds of opening and closing to take an hour off of a 4 hour encode by getting both cores into use.

Strange.
Here since version 4.3.1.222 everything is fine.

Both cores used, 100% each on 1st pass
of straight transcoding from WMV to MPEG2,
95-98% each on 2nd pass.

Of course lower when I export from Non Linear Editor
with various filters applied (EditStudioPro 5.0.1),
because this NLE has not yet been optimised for dual-core CPUs.

In TE4XP give 9000MB temporary space to use results from 1st pass.
The second pass is then definitely faster than the first one.

The previous version also used both cores of my T7600G OC@3.16GHz,
but each only up to 70& while encoding from DV-AVI to MPEG2.
So definitely something seems to have improved.

Emulgator, Since you are encoding to MPEG2 I'm guessing you'd get better use of both cores than for an MP4 encode. MP4 is fairly new technology, but programmers have had much more time to get MPEG2 figured out and optimized. That being said, I'm glad to hear that MPEG2 uses both cores at almost %100 with no problem. After I get done backing up my movies to MP4 I might transcode them to MPEG2 for better stability with media servers and video players that like slightly older file formats.

I'm having a framerate issue when converting 1280x720 MKV files to 1280x720 WMV. The MKV file is 23.976 fps, and when I convert it to an MKV at the same framerate, the playback seems slightly jerky. I've tried changing the de-interlacing settings, but nothing seems to work. Any ideas?

Might want to check your MKV decoder, see if theres any settings for playback. Is there any jerkiness when you preview it before encoding? It also might need a 3:2 pulldown to be 29.97fps.

Just chane the frames to 29.97 on the first page and then output it as a progressive file. Jerkiness goes away...

Hi, I was hoping someone here could point me in the right direction to help with a newly-developed problem I am having with TMPGExp 4.0. I had it working perfectly on my existing system (P4 2.53, 512mb crucial RAM, Gigabyte mobo) for h.264 encoding, frameserving an HD file from PPro CS3. I'm using XP Pro 64 bit.

But I've since upgraded the CPU to Q6600, mobo to P5K and RAM to 2gb Samsung DDR-800. All programs work ok after the upgrade, and TMPGEnc does also up to a point - when I get to the Format window, and choose "settings" to change/modify the encoding settings, it always crashes. I thought at first I had not installed all codecs needed on the new machine, but they are all there. Strange thing I found is that it WILL take my encoding presets saved before (eg h.264, high quality 1280x720), but still, every time I try to go into 'settings' to change anything about encoding, it crashes.

It only does this on the "quictime movie" encoding type, if I go to encode MPEG-2 for example, that works ok and I can change the parameters witout any problems. This is a strange one, anybody have any ideas? I don't think it's the new RAM as I can change other settings ok.

Thanks,
Patrick

You might want to check your external codec, Quicktime or other, might be corrupted. Close down any iTunes, iPod, Quicktime, or other quicktime h.264 related services/processes. Do you have XviD(H.264) installed?

Re-install Quicktime to see if that will help, most likely it is some other software that is causing TXP4 to crash.

Have both TMPGEnc 4.0, and DVD Author and I can't figure out a way to simply cut commercials out of a recorded TV show without having to recode the whole MPEG2 stream. Any help would be greatly appreciated.

Right now TXP4 needs to re-encode everything even if you don't edit anything. If you want to do edits without re-encoding or minimal encode then try their TMPGEnc MPEG Editor 2. Its the only encoding software that uses their smart rendering. Hopefully the next Xpress version will implement this.

Thanks nTekka, I feared as much. Can't figure out why they would drop this useful feature from v2 on a v4 of the product. Grrr.

I simply want to express my gratitude to the makers of TMPGenc and their generous free use of same. It has enabled me to create a dvd of an 8mm film shot 37 years ago.

Thank you very much.

First, I just wanted to thank you, nTekka, for your help in the past!

I have a couple of Matroska, MPEG-4 AVC videos, I'd like to convert to mpeg-2.
I was under the impression that tx4 could do this, but when I try to open with tx4, I get the error: "Cannot open file."
The file opens with all of my players, so all the codecs are installed... the highest priority to CoreAVC.

Is it possible to do this conversion?
If so, how do I configure tx4 to read it?

Any help appreciated... thanks!!!!

TXP4 can convert it, you will need some decoder first. Try K-Lite codec pack then open up TXP4 Options > Preferences > File input > uncheck AVI file reader and enable DirectShow file reader.

This should work, I used to do this for MKV and FLV before TXP4 supported FLV import.

Can the newest version of TMPEG make FLV files?

No the newest version can only import FLV files, it can't encode (create) FLV files. But TMPG might add it if they already took the steps of making it a supported input format, the output should be coming along anytime now.

I am trying to create MP4 playable on my PSP with TMPEG 4.0 (Trial)
The source is MJPEG, 15fps, 320x240.
I tried using ISO MPEG4, Portable Game console as container and several different settings (level 2 and 3, 15 and 29,97 fps, different bit-rates) but always the PSP tells me the format is unsupported.
Am I doing something wrong or TMPEG is unable to output this format?
I've looked everywhere (this and other forums, FAQs) but haven't find an answer yet, and my purchase decision relies heavily on being able to create PSP video.
Can someone help me?

The PS3 is somewhat related to the PSP, so I'll share what I've learned. For me the PS3 will only accept MP4's that use AVC, not the ISO setting. Try the AVC MPEG4 with the portable game console container, main profile, at level 2 or 3, and your original 15 frames per second. If the main profile encode doesn't work then you could try changing to the baseline profile.

If you want some somewhat convoluted but helpful reading on what the PSP can handle for MP4 then go here: http://www.pspvideo9.com/forums/viewtopic.php?t=4

Fuzz54 is probably right about the format. AVC also gives you a better quality and bitrate higher than 768kbps. Of course AVC format will also make your file size larger than ISO encodes. If you stick with ISO, then try changing the bitrate to CBR or VBR and setting the Quantization mode to MPEG instead of H.263. That might work.
