MVP and AVIs

[Spartan]

I reduce by size. So a full lenth movie I try to get down to 1CD or so. In case I want to back it up later. For a 1hr of tv I use 1/2 CD and a Half hour TV I use 1/4 CD.

It seems to fit about right. Quality looks good but this was before I started to force the FPS and resolution. I'm not sure what effect that will have on my next convert. I'll let you know. I'm going re-convert the Increadables tonight and compare it to my previous AVI. I expect that if you force the fps and the resolution the only other place it can shrink file size is the quality. I hope it doesn't go down too much, or I'll have to start making bigger AVI's.

Good to know -- I'll try one of those settings.

So last night, I encoded an episode of Bob the Builder (1/2 hour episode) at 75% as mentioned above and the avi actually came out larger than the source mpeg (I also set the output audio type to MP3 @ 128kbps VBR):

Code:

04/30/2005  08:02 AM       992,288,704 Bob the Builder_20050430_07300800.mpg
08/25/2005  12:48 AM     1,119,367,168 Bob the Builder_20050430_07300800_agk.avi

Wierd, eh? :confused: I'll start encoding it again at 1/4 CD size.

By the way, that avi works great on my MVP -- thanks for the tips!

Yeah I have had that problem with other encodeing. Not with AutoGK but other programs. Glad to hear everthing works. Did you force the resolution and FPS? I'm not sure what effect changing both was going to have. It might need to drop the resolution to meet the size requirement. I wont be able to do any tests until later.

What's the age range for Bob the Builder anyway? My son is 2 and like Thomas and Friends. I have never seen Bob the Builder.

Ok, the second encoding has finished and it came out at 178KB @ 352 x 272 & 123kbps. (The other AVI was 1.1G @ 720 x 560 & 224kbps). I won't be able to test the smaller AVI on the MVP until I get home from work.

I have identical twin 3 year old boys (turned 3 last April), and they love Bob. He comes on right before Thomas on my PBS channel on Saturdays (at least I think it is -- I can't remember b/c gbpvr remembers for me!) They're not big Thomas fans but will watch him every once in a while. I think it depends on their moods.

Thats much smaller. Let me know what it looks like

3 year old Twins huh? When do you have time for GBPVR?

Darn good Q!. I have a 2 yr old son and a 10 mth old daughter and they keep me very very busy, so GBPVR setup has taken a while to get where I am. Doesn't help when the HD packs in the middle of all this either.... :confused:

Well, I haven't got a chance yet to test out that small enconding -- maybe tomorrow.....

Bu Sub... Isn't there something that could be done about that framerate issue? I mean, what's the point of having to transcode so many files before it can be seen. You might as well just transcode it straight to mpeg, right?

Unfortunately frame-rate conversion is not something that ffdshow can do, but perhaps if an additional filter is pushed in the graph that takes care of this, the entire frame-rate issue could be resolved...

Nothing easy that I know of. I dont do AVI playback on my MVP, so its not something I want to focus much time on.

Exactly, then you'll have much more control over the process, rather than trying to do it in real time which is always like to have one problem or another.

Actually, it could be quite easy if you use Avisynth. Just generate a little AVS-script of 2 lines and then create the graph based on the AVS instead of the AVI. The AVS script could look like this:

Code:

AVISource("c:\the matrix.avi")
ChangeFPS(25)

Above is obviously for PAL settings, for NTSC settings it should be:

Code:

AVISource("c:\the matrix.avi")
ChangeFPS(29.97)

I actually intended to generate these scripts for each non-PAL video file and open the AVS instead, but unfortunately GBPVR doesn't see the AVS files and I haven't really been able to test then. I did check whether AVS files are directshow compatible through graphedit. I noticed that I can succesfully "render media file" when I point at the AVS.

Well Sub, I hope this suggestion would work, but can imagine that this is not really your priority. I noticed in other threads too that the AVI rendering doesn't really have your priority. Thanks anyway for a great product!

ffdshow/ffvfw has the Make_Avis tool that allows Avisynth scripts to be seen as .avis by apps that cannot read .avs directly.
