avi file with 119.875fps. Can i change this?

[meccaho]

I am using tmpgenc xpress to convert video and then other programs to burn to dvd.

Anyway, i have an avi file that shows it has 119.875fps. It won't encode correctly, the video freezes like 2 mins in but the audio keeps going normally.

I'm using ntsc format and it is a 640x480 video. Is there any programs to let me change the framerate to 23fps so i can convert correctly?

thx.

[Baldrick]

are you sure it is 119fps? check with gspot.

[meccaho]

yes...gspot says 119.875 as well.

I had already checked with mediainfo and tmpgenc xpress shows it as that too.

Open it in virtualdub. Use the file info option on the file menu to get the number of frames in the video. Use the length of the audio (time) to get the correct playing time. Now calculate the correct framerate using those figures. Then change the framerate from the video menu and save out a new copy using direct stream copy.

Hope fully you will now have a working avi file.

[meccaho]

ok....in the video tab, where do i change the framerate to what i want it at?

Under source rate adjustment, or under framerate conversion? I can do it both places...which one do i want?

Also, where do i get the option to save out a direct stream copy?

When i click on file, the save options i have are:

save as avi
save as old format avi
save segmented avi
save striped avi

But each time i choose one, all i have is the option to change the save as name, no other option to save as direct stream copy.

[meccaho]

ok...instead of virtualdub, i used virtualdubmod, which gave me the option of saving as direct stream copy.

After i saved it, the video was WAY too choppy. seemed like 1fps after the conversion. Unwatchably choppy.

I don't know what to do next, any suggestions?

[meccaho]

Ok, i figured it out...i encoded with tmpgenc plus, not xpress, and had the framerate change to 29fps.

Worked like a charm.

Was the source anime? Because sometimes such sources are a mix or 29.97fps, 23.976fps and 30 fps so for avi which is CFR they are converted to ~120fps.

[meccaho]

yes, it was anime....was there an easier way for me to change it to 23.976 or 29.whatever it is?

Hi-

was there an easier way for me to change it to 23.976 or 29.whatever it is?

You can probably do it quickly with no reencoding necessary. Open it in VDubMod and ignore the message it may give you about Improper MP3 (if that's what the audio is). Set Video and Audio both for Direct Stream Copy. Then go Video->Frame Rate->Frame Rate Conversion->Decimate By. Then set that for 4 for 29.97fps. Then go File->Save As... and give it a new name. If that works out OK, you then might try decimating by 5 to give you 23.976fps.

As celtic_druid said, these are 119.875 because they often contain a mix of 23.976 and 29.97, so making it 23.976fps may or may not make the 29.97fps parts play choppy. Often the Opening songs these days are 29.97, usually progressive. Be that as it may, I still prefer to make them 23.976fps. You'll have to try it for yourself. In any event making the 23.976 parts (which will be the vast majority of the episodes) play at 29.97fps will also make them stutter.

[celtic_druid]

Best way is to put it in mkv, leaving each section the original framerate. Really depends if you want standalone support, etc. though.

The decimating doesn't work for me. It just makes the video choppy and looks like its playing 1fps like the guy said above.

Is there any other way or a reason why it's not working???

[manono]

...a reason why it's not working???

It might have B-Frames, which will mess up the playback after decimation. GSpot should tell you that.

Is there any other way

You'll have to reencode, which I think you were trying to avoid. There are lots of ways to get it down to either 23.976fps or 29.97fps during a reencode. One way for 29.97fps using the Decomb Plugin for AviSynth would be:

Decimate(2).Decimate(2)

If you want 23.976fps, then:

Decimate(2).Decimate(2).Decimate(5)

A much faster way using SmartDecimate/TDeint to 23.976fps:

B=Tdeint(Mode=1)
SmartDecimate(24,240,B)
