Don't worry jorel,

I have a Macintosh PowerPC running Mac OS X 10.2.6 on my left with it's monitor, and my Pentium 1.6Ghz Running XP on front of me with it's monitor. Make a mental note: Mac monitor on the left, PC monitor on front of me :!: Both keyboards are in front of me, side by side. I usually use the Mac to browse (because OS X just doesn't crash at all :!: ), and use the PC to encode and do video stuff.
Many, and I mean MANY times a day, I'm writing at the Mac keyboard 8O, and looking at my PC's monitor, and shouting all kinds of bad words thinking my machine is locked up, when indeed I'm looking at the wrong monitor :lol:
Same thing the other way around too :mrgreen: Eventually, I'll get fed up, and I'll move the Mac keyboard to the left, where it's supposed to be :wink:
So my friend, if you're pressing F1 without a keyboard, you're fine :mrgreen:

Edting time?
 
Kwag...

I have been using the MPEG-VCR to cut commercials out of a regular 30 minute broadcast program.

I was using TMPGEnc to do the same (using the Cut editing under the ADVANCED, SOURCE RANGE options).

It seems like the total editing time is more using MPEG-VCR. The original file is usually 1.2-1.3 GB. Saving the non-commercial piece back takes longer than it does to just cut the commercials in TMPGEnc. Also, you do not end up with and original (1.2GB), a 2nd file without commercials (800MB) and the final MPEG1 file (150-300MB).

What is the advantage to the MPEG-VCR step. It works nice but almost exactly as TMPGEnc's editing interface.

Grantman

The primary advantage is the sync issue. In TMPEG, when you try to edit MPEG-1 VBR, the cutting points are incorrect some times. You must have noticed that if you scroll to some point in TMPEG in the Cut&Merge, and click on the play icon, sometimes it takes forever to sync and start playing. At least that's the way it worked the last time I tried it. Haven't tried it on the latest version of TMPEG. But on MPEG-VCR, it syncs fairly quickly, compared to TMPEG. I also had problems in the past when cutting with TMPEG. The cut points were not exactly where I had selected them.

Sorry it took me awhile to catch up on this. I usually do my captures from TV in avi and go from that point.

On the comment with Trim and avisynth. The way I get the audio (WAV) file, is to load the avisynth script into virtualdub and save the audio file in wav format. It's an extra step, but it gives me a wav file that sync's up to the audio with the commercial cuts in the right place.

Kwag... you are correct again!
 
I think the latest version of TMPGEnc does fix the weird sync issues. I have been able to cut out commercials perfectly... and the spots are right where they should be?

But...

MPEG VCR ultimately ends up being a better tool. Even with the sync fixed... it takes too long in TMPGEnc. Also, the cuts are only in the TMPGEnc project file and are easily lost.

Now, I take my ReplayTV files on to my PC. A 30 minute TV show is 1.2GB. I immediately cut the commercials in MPEG VCR. I queue up 5-10 shows and save. Then I delete the original files.

That has been saving me 33% file size on files I have not encoded yet. Also, it gives me a chance to work with the content before I am too far into the encoding process. It is a bunk file (wrong episode or something with visual glitches)... I find out sooner. Also... I think there are some clips that are easier to see Interlace lines if you are viewing them in MPEG VCR. That is how I figured out The Simpsons are Telecined. It was not as obvious in VirtualDub.

Thanks...

Each time it looks like a Swiss Army Knife is available (i.e. TMPGEnc) is becomes obvious that each process needs a specific tool.

You can't argue with the results!

Hi Grantman,

I'm looking into getting a ReplayTV :)
Could you cut and post somewhere a small ~10MB or so captured sample from the machine :?:
I would like to see the MPEG-2 captured quality :!:

Thanks,

Never mind GrantMan. I bought one :mrgreen:
