Hey All,

I'm about to encode some Bo Selecta captures I made for my SPV. What's everyones thoughts on which media app to use? PocketTV? PocketMVP?

Is mpeg worth the increased file size? What's the benefits?

Hey All,

Which MPEG...1, 2, 4? For that matter which DIVX (about 20 variations)?

My opinion:

Mpeg = Fast, bad image quality, large files!

DivX = Fast, stable & small files!

Definately DIVX!

Pocket MVP is the best all round player - video & audio. & with the virtualdub settings from Clint Eastman, the whole package works a treat for encoding videos.

Terwin, whichever mpeg version that PocketTV works best at. DivX would be 5.0.2, the version that PocketMVP (Seems to be called PocketDivX now) uses.

I've tried PocketTV briefly, but never encoded anything of my own. I've been using Clint Eastmans VirtualDub settings for DivX so far, but I don't think much of the frame rate I seem to get often. Just seems a little jerky for some things.

hehe not this old debate again.

DiVX all the way!

Err, perhaps I'm missing something quite large, but I can play mpegs at 20+fps on my SPV, and I've not got anywhere near that close with Divx.

Yeah the picture quality is slighty better with Divx (less blocky) but 8fps!!?

It seems pocket tv plays mpegs quite a bit better than pocketmvp.

Let me know what you think.. cheers

With out going into precise frame rates as Richie M said, this had been discussed before.

as you say mpeg = blocky picture = higher frame rate

Divx = better quality picture = lower frame rate

I know what I use and on a small screen do you need a high frame rate? Without

looking very close, with a decent divx conversion can you really notice a great difference?

Guest markdotpeters5

All down to personal preference then I guess. I'll stick with mpeg for now.

here's hoping my next smartphone will have enough guts to push a Divx at 24fps :)

is it me??? do i have a superfast spv.... NO

please try this divx on mvp and tell me if its slow....

i think you can get 20+ fps (ie like pockettv) with divx.

my big problem with divx is stereo at the same speed

i encoded this using my own setting, on vdubmod 1.5.4.1 with the new divx manchini (beta) codec.

the manchini is SLOW on max settings so i recommend not to use it. (like this took 8 mins to do)

5.02 is the most compatable version

i use pocketmvp 3e

ohh it wont let me attach.

anyone got some space, or can email it out to some.

I love these debates!!

I say Betamax is best!!

I get "This file contains an incompatible audio format" on that AVI in the DivX player. Has anyone got any suggestions how to fix it?

Guest markdotpeters5

Quite impressive that clip. smoothest Divx i've seen myself. any chance you could export your settings for me to play with?

cheers

these are the settings for vdubmod

if you want to have a go yourself (with any version of vdub) to find your fav settings:

1. open file with vdub

2. go to the filters page (on the video tab)

3. add rotate (not rotate2) option right 90 deg

4. add resize (i use 164w x 220h) on the mode i use lanzos3 but that preferance

5. close filters and open stream list in streams

6. right click and choose full processing mode, them right click again and choose compression. i use divx mpeg layer-3 at 16kBits 11025 Hz Mono. ok it all

7. choose compression from video.

8. choose your installed divx codec and configure it for around 100 kbps

thats it

i've no idea what's up here, but using those settings, I get a horribly jerky video.

I've matched the framerate, the resizing options, everything, and it's awfully jerky.

Odd eh?!

My opinion:

Mpeg = Fast, bad image quality, large files!

DivX = Fast, stable & small files!

Our opinion:

Mpeg = MPEG-1. Easy to decode by software-only, good image quality (if encoded with the appropriate resolution, bitrate and other parameters), reasonnably small files. Many excellent tools available for encoding (free and commercial).

DivX = based on MPEG-4 and MP3, which uses more advanced compression, also more complex. Harder to decode by software (hardware acceleration recommended), good image quality (if encoded with the appropriate resolution, bitrate and other parameters), files should be about 20-30% smaller than MPEG-1 files for comparable audio and video quality. Not a large choice of tools available for encoding.

Check a few MPEG files optimized for Smartphones, and you'll see that the files are reasonnably small and the quality is good:

http://www.pockettv.com/mpg/sp/officexp-sps.mpg (30s, 400KB)

http://www.pockettv.com/mpg/sp/mikes_new_car_sps.mpg (1min 11s, 1.1MB)

http://www.pockettv.com/mpg/sp/405themovie-sps.mpg (3min, 2.7MB)

To make those files, we used TMPGEnc with the templates available here:

PocketTV Classic is free from http://www.pockettv.com

I have to agree, although you obviously have a conflict of interest :)

Since SD cards are so cheap, I think I'll stick with mpeg for now.

Slightly off topic, but does anyone know if the SPV has a limit to the size of SD card it can support?

cheers

I shouldn't have an upper limit. SD cards are designed to handle that...it's not like a normal storage device that's memory addressed. IIRC that is.

Price on the other hand is the real limit. You can get 4 256 cards for the price of a 512 last I checked.

Guest markdotpeters5

Yeah, but it's all about convenience. Ebuyer are doing a 512mb card for just over £100.

We're going a tad off topic here :)
