hi you all,

i did more testing (kvcdx3) with my problems and here is what i have found...

1- finally it worked with tmpgenc & bbmpeg...for tmpgenc i set cq at 60 and did not have an illegal floating point message...it gave me a file of 500 mg app....no message from bbmpeg also with this rate (it was able to write to output file)...so those settings worked finally...

2- retried everything with cq at 70 with tmpgenc and it worked again no error message but when muxing with bbmpeg it stopped at 98%...it was not able to go at 100%...can i use this file anyway...

3- tried with my real cq value (75,53)...ok with tmpgenc no error but bbmpeg is stopping at 82% with the same message...unable to write to output file...

4- tried also tmpgenc with cq value of 80 or higher and it is always giving me the illegal floating error message...

5- am i losing to much quality with a low cq value for that template (kvcdx3) or is it better for me to use only the 352 x 240 which is working?

6- since a low cq (60) value is working for me for kvcdx3, are there other settings that we could use to improve the quality or will i have better results with another template???

thx

big

Hi big,

Are these errors on the same movie (source), or can you reproduce the same errors on other sources

Have you tried getting rid of your current CODEC and installing another CODEC. Maybe XviD? What is your currenc avi CODEC

Hold on . When you meant avi, does this mean that you are capturing with MJPEG
If this is the case, have you tried capturing with the Huffy CODEC, and then processing that

Give the Huffy codec a try

No. But remember that your captured MJPEG avi's must me viewed with MJPEG CODEC. You can't read MJPEGs captures with the Huffy codec.
Now you can do some test captures with the Huffy codec and then process them with the .avs script. Huffy and MJPEG are not compatible.

Yes I believe that is the latest. You download the files and then "Right click" on the huffyuv.inf and "Install".
After that, if you use VirtualDub, etc., to capture, you'll see the new codec installed on VIDEO compression options.

Now you can do a capture with the Huffy codec selected instead of MJPEG.

you mean that i load my script in vdub and choose huffy in the options?

because to avoid illegal floating point in tmpgenc, i startred frameserver in vdub, save .vdr and load the .vdr in tmpgenc...

excuse my dumb dumb questions...
