i have found big data spikes per FRAME in CBR mode with TMPGEnc, which is a shame as its generally brilliant. Does anyone know how to alter the data load across frames or smooth out these spikes?
per second data rate is fine.

i am encoding MPEG1 for some networking project which is less tolerant. The spikes are up to 66 Kbytes per frame when encoding at 1600 Kbits/sec. It is loading up 1 frame of the 25 with a third of the data (66Kbytes) when an average should be 64Kbits. Up to 50Kbytes per frame would be ok but 66 is just too big.
Any ideas appreciated!
Thanks.
Hmm... i have a problem that could have the same root-cause.
If i play a VCD encoded with TMPGEnc (standard VCD-PAL-template) on a DVD-player, then sometimes the video jumps. It looks like one frame is missing and the player then simply repeats the old frame.
These jumps are always on the exact same place in the video.
If the datarate of one frame is way to high, then this could be the cause.
If i change encoding to better quality, then the place where these jumps occure do change, but they are still in.
I looked into the file with Bitrate-viewer... but i could NOT see big datarate-spikes.
lu: With which tool did you detect the datarate-spikes?
a friend of mine can work it out but i don't actually have a tool. I have been looking for one as well but no joy. If I find one i'll let you know.
It would be really cool if we could work this out!

To make sure that we have the same problem i could encode a short part of movie, check, that this part has this problem, and send you the mpg-file.
Could your friend then check, if there is such a spice in?
Or maybe you can ask him which tool he uses?
I used the bitrate-viewer, and with this i could not detect a spice.
I've tried using TMPGEnc 2.53.35.130 to split a large MPEG2 file into 3 sections, using the Merge & Cut MPEG tool. While the split is successful, the video overruns past the end of the first two selected sections by about 30 seconds. The audio stops where it should. Sync between both is fine.
When making vcds with TMPGENc I get some audio problems, namely there's a lot of hissing and buzzing at higher fequencies, eg. female voices.
I know the source audio file is fine
Any reason for this problem, settings that might help?
Thanks

rip the audio first, before encoding to vcd mpg, and use the correct bitrate
use virtual dub (freeware) goto vcdhelp.com
open the original divx file
goto to file > file information
note the framerate for encoding later
goto audio > full processing mode (select this)
goto audio > conversion... and select 44100hz
goto audio > compression... make sure no compression PCM is selected
goto file >save wav name the file and wait a few minutes
after encoding's finished open video file in tmpgenc and open the wav file you just created as the audio source file
you can now encode and select the range, etc, as you normally would
i hope this helps
happy converting :o)
Hi,
I am having quality problems when I use the DirectShow Multimedia File Reader (VFAPI)
The VCD movie that is created using this reader, results in a movie with a lot of jumps when any kind of motion is involved.
When I use the other 2 readers (AVI2-OpenDML, AVI-VFW) there are some jumps in the resulting movie also but the result is much smoother compared to directshow.
I am very new at using this program, but I have a question concerning the quality of the resulting MPEG1 video I've been getting.
Basically, I have a whole bunch of downloaded Divx-encoded AVI videos (NTSC). All I need to do is convert them from AVI format to VCD (MPEG1) format, and then (later) burn them. I've been able to do the conversions, and I've also had success burning them with Nero.
The only thing I'm wondering about is that the quality of the resulting video tends to be lower than that of the original one. I've messed around with various options without getting any better result.
The input videos are either full-screen or wide-screen, but I prefer keeping the black bands on the top and bottom of wide-screen videos. I've tried all of the settings of "Motion Search Precision", I've changed around the "Video Source" and "Field Order", and also changed the "Source Aspect Ratio" and "Video arrange Method", but the quality doesn't improve.
The only other thing which I had to change early on was to increase the priority of the "DirectShow Multimedia File Reader" under the "VFAPI plug-in" tab in the "Environment" section because certain files were "unsupported". Doing so fixed that problem.
The thing is, the resulting video doesn't look horrible - I'd say it's about 90-95% of the original one in terms of quality. I was just wondering if that was normal.
Any help/advice any of you can offer would be greatly appreciated.
Also ... don't forget that the standard resolution bitrate of VCD (1150) will give rise to a blocky effect. The way to counter this is to up the bitrate and/or the res. This means in effect that you are creating a non-standard VCD - an XVCD
I'm trying to merge 2 mpg2 files so I can author the mpg file. both are the same specs. I open up TMPG2.53 and select mpg tools merge and add my mpgs...
1.)000.mpg[3.72gb] and 2.)001.mpg[222mb]Now I run the program to merg the two...it stops at 10% and says out of memory. What does that mean and how do I fix it.
My sytem consist of:
Windows 2000
P3-1ghz
768mb PC133 ram
40gig HD for video files
20gig HD for operating system
my windows paging file is 8095mb for all my drives
What difference does the audio 'Sampling Rate' make when Encoding mpeg-1 for playing on a DVD player. Does it have to be set to a certain value for NTSC COMPATABILITY or is this just a quality thing? I just burned a video to disk and the sound was there for the first 30 sec. then nothing for the rest of the video, but when I play the same mpeg (from file) on my computer the sound is perfect?!?
Actually I just realized that the sound disappears only when i skip ahead (fast forward) on my DVD player. Then the sound completely disappears for the rest of the video. I've been having this problem alot when I burn them, but I just realized this fact. Is it a possibility that it's from using the cheap burning software I got with my burner?
I can convert the video of any SVCD(.m2v) into VCD file ok. The thing is, there is no audio when I play. What do I have to do in order to get the audio to be in the final VCD without separately getting just the audio. ?
I purchased the s/n to register but I just noticed there is no splash screen. I have uninstalled and installed several times and it still wont come up to register. is there a reg key I am missing? hummm.
First of all, this is wrong place to post such matter.
I have purchased the Plus version, so I know you have received E-mail
which include serial number. The E-mail message tells everything.
You should read that, then you will know what to do for sure.
As I said I am trying to convert avi to vcd using tmpgenc...and would like to know
1) If I use no margins is it guarenteed that it will come out fullscreen as the preview as well as media player doesn't reflect this.
2) Can I use the crop filter and still get proper fullscreen?
3) How can you tell what source aspect ratio to use ...and what happens if you choose the wrong one.
I am needing some direction as I don't want to keep wasting cd's to find out its not what I intended it to be.
Thanks
Jules
I have been wondering about the Wizard's settings when loading my 7.3gb NTSC Video movie. The Wizard checks my AVI and sets as follows:
* CBR (normally, I use 2-Pass VBR (new) and sets ave and min)
* Full Screen (should this be Full Screen (keep aspect ratio?) I use Full Screen
* 4:3 525 (NTSC 704x480) (should this be 1:1 VGA? but I never us it)
* Bit Rate: 2520 (normally, I use smaller to maintain compliance)
* Motion Search Estimate (isn't this just for 2-Pass VBR and can it cause blocky picture on TV?)
* Stereo 44K (can't I use 22K and still maintain good enough audio?)
* MP@ML (isn't this DVD setting?)
* No motion search for still picture (can this cause blocky picture... my experience?)
I use Pinnacle Studio 7.13.5 to edit then encode my DV to AVI, then TMPGEnc to MPEG2 (480x480). Then, I burn to CD using NERO 5.580. Most of the time, they play very good on my Hitachi 505 stand-alone DVD player and A/V surround system. I use Win XP (Home) on my P4 with 2 separate drives.
Thanks for the tips on the TMPGEnc settings. I will try it to convert my Studio-7 AVI to MPEG-2. I have attempts various setting sin method last week, and my MPEG-2 got a lot of jitters around the image edges especially when the object is in motion. So I tried Nero to create my SVCD disk directly from Studio-7 AVI files and It worked for me with pretty good quality.
If you decide to try Nero please let me know your observation about the pic quality: Nero vs TMPGEnc. Thanks.
