How to frameserve to Procoder Express ?

[Zetti]

Hi all,

I'll re-encode a M2V stream, as far as I've realized, to avoid deep loss of quality, it'd be better to frameserve to procoder instead of loading the M2V stream directly into it, right ?

But I've realized that, unlike TMPGEnc, Procoder doesn't accept D2V files, is there anything similar I could use, specially as easy as DVD2AVI ?

Thanls,
Zetti

Have you tried Avisynth? I know Procoder 1.5 accepts avisynth scripts as input, but I'm not sure with Procoder Express.

No, thanks, I really don't wanna "touch" the video, just reencode;
I thik I'll follow the traditional DVD2AVI - TMPGEnc indeed;

and why not just load the m2v or vob file directly ? best quality really .

Thanks, have just replied to that;

I am confused, BJ;

As far as I understand, loading a D2V file into any converter would make it look at the "AVI" uncompressed file, as far as I understand frameserving serves to "mark" the AVI frames without actually building an uncompressed AVI file, so it saves time and at the end the converter would be doing an AVi to MPEG2 conversion instead of a MPEG2 to MPEG2 conversion,

Am I wrong ?

Thanks,

Zetti

you are wrong ...

avi first off is just a wrapper for many file types you know you can have a mpeg avi file even ?


since the source is mpeg -- and the target is mpeg .... well the source has to be decompressed no mater what , if you do it by frame serving or by directly loading it .. it is still got to be decompressed at some point ..


it is not just mpeg this is true for -- any type of video file (except raw uncompressed frames or streams) has to be decompressed to be encoded - this goes for qt , avi or whatever ..
even some so called uncompressed formats still have color compression ..

frame serve does not bypass this step .. if it did , you would have no picture

proof of this is to remove the codec needed for decompressing .. if you remove it , frame serving or not , you will have nothing ..

if the frame server did in fact not have to decompress the video - it would have not needed the codec ..

procoder xpress and version 2 use a special method to read mpeg2 files .. vs. how it displays .. info is thier manual .. it is a very good way they are doing it for consistant results.

[Zetti]

Well, BJ, thanks for writing....BUT....if it makes no diference, what is the advantage of frameserving ?

Why sw's like DVD2 AVI do exist ?

Thank you,

Zetti

back in the dark days of mpeg re-encoding .. not many encoders would accept mpeg files (some still dont) or vob files or treat multiple vobs as one file ...


also -- back then -- people were making vcd and sometimes svcd - so resizing was happening , as well as other things .. most encoders didnt do that either ...

dvd2avi is still excellent - and also can display if film or or not frame rate source ..

When I frameserve from VirtualDub, I create a file called 1.vdr
CCE, Mainconcept and others can recognise this and pickup the frameserve.
Will Procoder Express do the same

if you use vfapi wrapper on the vdr file

if you use vfapi wrapper on the vdr file

Sorry you've lost me....How do I use vfapi wrapper on the vdr file

[erratic]

You probably don't have to use vfapi. BJ_M himself has found an easier way. Try it. It certainly works when frameserving from VirtualDub to Procoder 2, but I haven't tried ProCoder Express.

If it doesn't work with Express read this frameserving guide. VFAPI usage is explained in there somewhere.
