TMPGEnc thinks I have 739105 frames!

Postby Phade » Thu Oct 03, 2002 6:26 pm

Hey,

I'm using TMPGEnc to recompress my Material Girl video (now that have the uncompressed source again and a guide this time). I'm on the Inverse Telecine step and it says that I have 739105 frames in my movie, which seems to be excessive. It seems to be going throught them just fine, but it will be sometime tomorrow before I can check the results. The video plays fine as is, though.

What's the problem and is there a way to get the normal frame rate back so that it will process faster?

Thanks in advance! ^_^

hmm.. according to that the video would be 6.8 some hours long :shock:
erm.. howsabout using decomb instead of tmpg to do the ivtc. If you aren't already feeding TMPG an avisynth script, all you have to do is make a new script saying

AVIsource("pathtoMaterialGirl/Materialgirl.avi")
LoadPlugin("pathtoDecomb/Decomb.dll")
Telecide(Guide=1,Gthresh=40,Threshold=20,Chroma=True,dthreshold=10,Post=true)
Decimate(cycle=5)

and load that into tmpg as well as the audio from the avi

if you need decomb you can get it at http://www.doom9.org/software2.htm#filters

and if you dont have avisynth, it should be somewhere around there as well

er.. unless its not interlaced, then you dont need to ivtc at all 8)

Hey,

I've figured out the cause, but I don't know th solution. The cause is the quicktime reader for TMPGEnc. There seems to be a bug in it that, under the conditions that I have it running (however odd they may be, but they seem to be normal to me), makes TMPGEnc think there are exactly 100x the number of frames that there really are. Hmmm...

I get the same problem trying to use Quicktime files in TMPGEnc. Here's some information:

Code: Select all
 
[tcprobe] Apple QuickTime movie file
[probe_mov.c] codec=twos
[tcprobe] summary for test-tmpg.mov, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
       frame rate: -f 23.976 [25.000] frc=1 (*)
      audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x1 [0x2000] (*)
           length: 152 frames, frame_time=41 msec


Tried running Quicktime files using v308, v408, yuv2, and RGB (above). All contained interlaced video. qtreader only understood the last format (oddly enough, all of them are standard QT codecs...oh well), and the IVTC filter (actually, any filter I tried) told me that I had 152,576 frames in the file. Timebase of the preview bar: 19,200 fps.

Oddly enough, the encoding process itself doesn't seem to have a problem recognizing that there are 152 and not 152,576 frames in this file. It's the filters.

Hmm.

Hey All,

Ok, I got it to work, but it was a long strange trip to get it there. First, there was the bug in the Quicktime reader plugin that made TMPGEnc think there was 100x the number of frames that there really was (as stated above).

I then found a tool called RAD Video Tools that could convert QT to anything else. I had it dump an uncompressed AVI out, but the resulting 4G file was unreadable by everything, even VirtualDub. So much for that idea.

I got opened the clip in Quicktime and exported it as an uncompressed AVI. The resulting 4.8G file was not readable by anything, but VirtualDub could open it and "recover" the missing parts to the file. I had VirtualDub then reoutput the file using Huffyuv. That resulted in a 5.1G file (what's up with that?). This really big (?) file was readable fully by TMPGEnc.

So the recompression is commencing (in fact, TMPG is running the force field detection as I type).

Thanks again and have fun!! ^_^

Hey,

The reason I had to use Quictime at the time was because I was using a Matrox G400-TV and Avid Cinema. It uses a hartware MJPEG codec to do its stuff. If I exported as AVI, the only place I could play the video was on the machine with the G400-TV. But if I exported using Quicktime, the video could be played anywhere without the additional hartware. So, I went for the highest playback compatability (playback everywhere was a better idea than playback only on a machine that I was replacing the video card on anyway).

Thanks again for your help and have fun!! ^_^

I think Gx00-TV AVIs can be loaded in VirtualDub on a machine without the Gx00-TV card since it has built-in MJPEG routines, but I'd have to check.

Hey Dokidoki,

Yeah, I finally figured that out, but I didn't know that way back then. All I knew then was that the QT source could be played elsewhere.

Now if they only made the DV500 for laptop... :D
