Hi - I've been capturing TV shows and home video for the past couple of months using an AIW Radeon card and LOTS of help from the FAQs etc on this site
I am having a particular prob in cutting MPEG1 clips with TMPGenc though. I doubt this problem is unique but I haven't been able to find it on any searches, so please help...
I've done a fair number of captures in MPEG1 format - with bitrate set at 1.89 kbit/s. Using Merge&cut in TMPGenc, if I cut a section from the middle of the file, then the output I get starts at a position earlier than I selected and also ends earlier than I selected. Checking the timings more closely, the actual cut positions are out by around 0.9 sec/min. So now I have to find the time where I want to cut, multiply that (in secs) by 1.015, then move the pointer over to that position to make the start or end point. This does give me more or less what I want, but it is quite inaccuarate - i.e. you can't be accurate to a single frame, but it is never out by more than a second.
This is getting to be a real pain. Do I need to tweak some settings somewhere? Are not all bitrates supported by TMPenc???
Thanks,
Alan

Maybe a bit more info would help here...
I'm using a 1.4MHz Athlon setup under Win ME
My TMPGenc is v2.01.30.116
I get the same trouble with MPEG-1 clips captured using VCD 2.0 compliant settings (a al Stinky). BUT I just tested the MPEG-1 .DAT file from commercial VCD, and that cuts perfectly. Curious...
Any help would be very gratefully received
Thanks,
Alan

I tried using tmpgenc as an editor and i found it to suck goats--i always got that out of sync problem and then would have to go and re-synch it --not hard but pain in the ass--there is alot of info in here if you want to do it that way. I just started using vcd cutter and it works fantastic on mpeg1 movies but i haven't tried it yet with mpg2 or anything else yet--you can either buy it from these guys in japan or (like most people) you google search it and find somene that has posted the whole version. It edits real quick and doesn't need hours to re-encode everyhting. Have fun

The TMPGEnc cutter seems to be a fickle thing.
I've literally cut hundreds of VCD compliant MPEGs (usually encoded with Panasonic) and I always get frame accurate cuts and never have A/V sync problems...
It seems that TMPGEnc has difficulty cutting MPEG-1 files from specific sources/encoders. If you've had problems with TMPGEnc as an MPEG-1 cutter (A/V sync problems, location accuracy problems) please post on exactly how your encoded your MPEG-1.

Here's my stats:
PIII 667
512MB
40GB 5400 Maxtor
ATI 64MB DDR Radeon VIVO
I have captured (so far--as I'm still new to this game)
Mpeg-1 @ VCD compliant stats (no variation whatsoever)
Results:
Good capture (considering vcd quality) and no sync problems and so few dropped frames that I'm thinking there weren't any (I'm not sure how to check really) When i try to use tmpgenc or media studio 6, I get synch problems AFTER editing. No problems with vcd cutter. -
Well I think the sync problems are not setting the stream settings before cutting it in half so its saving it as an mpeg systemstream instead of vcd stream but as far as the when I cut it being any secs off Im running 1gig athlon and I havent had these problems I am curious though whats causing it for you but you maybe right it maybe the stream settings what a minute if your capturing at 1189 bitrate for vcd tmpgnec's vcd stream is 1150 so that maybe your problem let me know what you find out

Thanks for your help guys.
This is what I've been using:
ATI AIW Radeon 32MB with latest official drivers
Athlon 1.4 / Win ME/ 40GB 7200 HD
MMC 7.1
Burning (X)VCD with Nero
Input: composite video (PAL) from camcorder or digital TV
Not sure if it makes any difference but my MMC is the TV Wonder version - downloaded it by mistake and it worked. Tried the proper AIW version later but it kept crashing with the "Pause Live TV" option, so I went back to the TV Wonder version (didn't like having the self-destruct buttons so close to record!). Everything "seems" to be working now - it took me a long time to get here so I don't want to tinker too much with it now...
I have followed Stinky's instructions and used the registry tool to set captures to VCD 2.0 compliant settings. Most of my captures are on this, or with variations in bitrate (e.g. 1890 as I said before).
When using TMPGenc, the Merge&Cut is set on MPEG-1 (automatic). Maybe I should be using the VCD setting? The 0.9 second per minute "offset" seems to be independent of bitrate (that's video bitrate - not sure about audio...). I have had occasional sync problems, only but very rarely.
I'll keep trying and tweak as many settings as possible - will let you know if I figure out what's wrong. May also check out VCD Cutter as well...
Thanks again

I've now tried using VCD Cutter with my problem MPEG-1 files...
1. It cuts in the right place with 1.15 and 1.89 kbit/sec files.
2. Audio in the produced clip is fine and in sync.
3. BUT the video in the clip stutters really badly at the start. It gets back to normal getting near the end of the clip though.
There is clearly something very non-standard about the files I'm creating....
Cheers,

Yah, i had that problem at first--check your version of VCD cutter (i think 4.04 is the latest). Once I got that and then multiplexed it through tmpgenc, all worked fine--you would think that after landing on the moon and sending probes to outer space, video editing would be a little easier??
let me know if you need a keygen to access full vcdcutter. -
Just curious, what are youre settings capturing (resolution, bitrate) and what kind of quality are you getting? I did the white book VCD 352x240 at 1.15 kbits/sec and i thought the quality sucked--lots of blocks etc--I then upped the bitrate and got good quality. Any tips on reducing the filesize while maintaining quality are always appreciated

Menace - Thanks but I'm already trying out a current version (4.04) of VCD Cutter. I'm not sure how to multiplex it through TMPGEnc (need to check out more of the FAQs) but I was looking for a simple method - just select the start and end points of the clip I want and press a button to make it. Sounds easy in principle but not in reality as you point out!
My MPEG-1 captures are made at 352x288 (PAL), 25 fps, 1.15 kbits/sec, or whatever - the suggested PAL version of VCD 2.0. Motion estimation is at 100%, VCD bit set (using Stinky's tool) and VBR off. The quality is just about OK but certainly quite blocky at times. For better results I like to go above 1.3 kbit/sec if poss. The 1.89 caps look pretty good on my DVD player, but I'm no perfectionist -
We have a solution (well it worked last night - hopefully will work again!)...
As I already said, I noticed that clips I make using TMPGenc from my original MPEG-1 files are cut in the wrong position, BUT (as I discovered last night) if I load those clips back into TMPGenc, it cuts precisely in the positions that I select - no problems.
So my solution is to capture excess video in the first place. Then trim it a bit with TMPGenc - the trimmed file can then be loaded back in and I can cut that just like everybody else can. End of story.
Thanks for all the suggestions
Alan
