Convert DV files to ????

[Ghitulescu]

Ahhh still got the original PAL DV - and for now I've transcoded to MPEG-2 @ 15Mbps CBR / I-Frames only with TMPGenc.....

You finally got the solution.

[2Bdecided]

If you want to encode MPEG-2, there are plenty of other tools that will avoid TMPGenc's limitations.What's drag-and-drop-able or batch-able from DV AVI to MPEG-2? No intermediate stages or mouse clicks.

(Free would be good).

Cheers,
David.

you would write a batch file that would:
1.
a. make temporary avisynth for dv avi files
b. determine if the dv is either 4:3 or 16:9 (mediainfo)
c. send all that to the hcenc with some correct encoding parameters (i think you can stuff everthing to the command line with later versions of hcenc, so no ini files needed)
d. convert audio and mux with video
or

2.
a. use mencoder to do the job
or

3. (payware)
a. use something like procoder

AFAICT 2 isn't much easier than 1!

...and my .BAT scripting skills certainly aren't good enough for 1.

Cheers,
David.

i can give it a try tommorow maybe, what kind of audio is prefered? pcm?

[2Bdecided]

mp2 for me, but YMMV OP.

[Ghitulescu]

For an amateur made footage, there is no sensible difference between MP2 and LPCM. If you plan to rework the footage later, use LPCM, if not use MP2 (or AC3 if you're American ;)).

known issues:
.soundout plugin will cry if it can't find an audio file (needs unnecessary user intervention), this could be solved by finding better soundout defaults or maybe checking the file ifsound=true before that...
.stereo 48kHz input is expected
.mediainfo DAR detection may fail (not tested that much & the code is pretty dumb)
.only tested with PAL DV footage

HCencDVauto_tcm.bat
for /f "delims=++" %%i in (%1) DO HCencDVauto.bat %%i

usage:
a. drop all dependencies somewhere on the system path
b. config the hcenc path
c. test from cli,
HCencDVauto file.avi
d. make sure HCencDVauto.bat is also somewhere on the system path
e. attach HCencDVauto_tcm.bat to total commander, like so (edit start menu or make a button):
Command: T:\path\HCencDVauto_tcm.bat
Parameters: %L
you can now select avi files in any pane and click the button/menu entry you just did to start the process (this will only work on multiple files, can't browse over dirs)
